Emotional Engineering, Vol. 9: Move Ahead Toward Self-Satisfying Society (SSS), 開始ページ:91, 終了ページ:111, 2022年01月
Emotional responses to color stimuli are referred to as color emotions. The current study reveals the relationships between color rendering properties and color emotions pertaining to facial skin colors, by using a light system that controlled the color rendering property. This study summarizes two previous studies. The first study examined color emotions toward facial skin color under various color rendering prop-erties. The second study assessed the relationships between color emotions using an average face irradiated by various illuminants with different color rendering prop-erties. Based on the models of the relationship between color emotions and color rendering properties obtained through these studies, a comparison of skin color itself and color emotions toward facial skin color are discussed. Specifically, the results suggest that color shifts in the red and green directions have different effects on the impressions of single colors and average faces.

Herein, we developed a machine-learning-based multivariate gait feedback training system to address the recent increase in the number of people requiring nursing care. Our system considers the physical differences of trainees in order to provide effective gait training and to reduce the burden on caregivers and physical therapists. We focused on “stumbling” as a target of training and examined the immediate effects of this training system and evaluated the effects of one training session in terms of the thumb-to-ground distance, joint angle, and floor reaction force. As a result of the experiment, participants’ thumb-to-ground distance increased significantly, indicating the effect of training on stumbling. In addition, the results showed that each part of the body and the timing of the trainee’s gait can be adjusted to satisfy the important criteria that determine the ideal thumb-to-ground distance and that each individual has freedom of flexibility in other areas.

In recent years, as bicycle delivery services and shared bicycles have become popular, an increase in the simultaneous use of bicycles and smartphones has been observed. Thus, collisions of pedestrians and cars have increased, becoming a social problem. The cause of this problem is considered to be the reduced attention span caused by gazing at a smartphone, which requires the development of a safe driving support system to prevent accidents. In this study, as a preliminary step toward the development of a system, we first examined the effects of looking at a smartphone on the attention span of bicyclists. The results indicated that looking at a smartphone reduced subjective attention, but there was no correlation between the distance between the appearance of a pedestrian and the collision.

In recent years, conversations over the screen with the face visible have become useful for meetings and lectures. If the listener does not seem to respond, the speaker’s ease of speaking may change depending on the presence or absence of entrainment. We also confirmed entrainment depending on the presence or absence of the listener’s reaction. While the speaker was speaking, we obtained fingertip plethysmographs and cerebral blood flow for each of the listeners and speakers. From the results of this experiment, synchronization of brain activation was observed at specific sites depending on the response of the listener and the type of conversation. Many entrainments were observed in the heart rate variability during face-to-face conversation and the nodding response. From the above results, it can be concluded that the occurrence of entrainment depends on the type of conversation and the response of the listener.

Recently, a path navigation system for visually impaired persons was developed that provides direction using three-dimensional (3D) audio. However, the path navigation system only provides the directions to a destination—the person cannot perceive either the shape of the room or the obstacles. Therefore, we investigated the effectiveness of 3D audio in spatial perception under visual restrictions. We conducted a spatial perception experiment and a walking experiment to confirm how accurately people can perceive spatial information by moving a sound source using 3D audio. In these experiments, we developed a mixed-reality application to provide spatial information in a virtual environment. A noise sound was presented and moved along the shape of the virtual room. The experimental results suggest that people can perceive spatial information and walk around the room by moving a sound source along the shape of the room.

Several training methods have been developed to acquire motion information during real-time walking; these methods also feed the information back to the trainee. Trainees adjust their gait to ensure that the measured value approaches the target value, which may not always be suitable for each trainee. Therefore, we aim to develop a gait feedback training system that considers individual differences, classifies the gait of the trainee, and identifies adjustments for body parts and timing. A convolutional neural network (CNN) has a feature extraction function and is robust in terms of each feature position; therefore, it can be used to classify a gait as ideal or non-ideal. Additionally, when the gradient-weighted class activation mapping (Grad-CAM) is applied to the gait classification model, the output measures the influence degree contributed by the trainee's each body part to the classification results. Thus, the trainee can visually determine the body parts that need to be adjusted through the use of the output. In this study, we focused on gaits related to stumbling. We measured the kinematics and kinetics data for participants and generated multivariate gait data, which were labeled as “gait rarely associated with stumbling” class or “gait frequently associated with stumbling” class using clustering with dynamic time warping. Next, the multichannel deep CNN (MC-DCNN) was used to learn the gait using the multivariate gait data and the corresponding classes. Finally, the data for verification were input into the MC-DCNN model, and we visualized the influence degrees of each place of the multivariate gait data for classification using GradCAM. The MC-DCNN model classified gaits with a high accuracy of 97.64±0.40%, and it learned the features that determine the thumb-to-ground distance. The output of the Grad-CAM indicated body parts, timing, and the relative strength of features that have an important effect on the thumb-to-ground distance.

Emotional responses to color stimuli are referred to as color emotions, and relationships between color attributes and them have been discussed in past studies. In the current study, we reveal relationships between color rendering properties and color emotions pertain to face colors by using of a light system controlling color rendering property. The system we developed in the previous study has four color (red, green, blue, and yellow) LEDs to enrich color rendering property. This study provides a comprehensive discussion of color rendering properties and color preference to average face by summarizing past two studies. The first study examined color emotions against skin color under various color rendering properties. As a result, we confirmed that the color rendering property certainly affects color emotions, and we obtained regression models to represent color emotions by color rendering properties. The second study assessed relationships between color emotions against averaged face irradiated by various illuminants with different color rendering properties. As a result, we confirmed that the color rendering property certainly affects color preference, and we obtained regression models to represent color emotions by color rendering properties. Based on the model of the relationship between color emotions and color rendering properties obtained through these two studies, a comparison of skin color itself and color emotions as a face color is discussed. Specifically, the results suggest that color shifts in the red and green directions have different effects on the impressions of single colors and average faces.

Several training methods have been developed to obtain motion information during real-time walking and feed it back to trainees who adjust their gait to ensure that the measured gait parameters approach target value, which may not always be suitable for every trainee owing to physical differences between individuals. This paper proposes a method of setting this target value considering these physical differences and discusses the usefulness of the gait training method, wherein a multichannel deep convolutional neural network (MC-DCNN) gait classification model constructed by learning ideal or non-ideal gait features beforehand is used for trainee gait classification. Activation maximization is applied to the MC-DCNN model; data wherein the ideal walking features are activated are generated based on trainee gait data. However, the amounts of features to be activated to generate a possible and natural gait are restricted. The original trainee gait, beyond individual physical differences, and gait data generated based on the original gait data seem to yield the target value considering the physical differences among individuals. This study focused on gait related to stumbling. To verify its usefulness, a multivariate gait dataset consisting of kinematic and kinetic indices labeled as “gait rarely associated with stumbling” or “gait frequently associated with stumbling” was divided into a training set, validation set, and test set. The MC-DCNN model learned gait features for multivariate gait data classification in the training set. It classified the gait with 96.04±0.12% accuracy against the validation set. Finally, by applying the proposed method to the multivariate gait data contained in the test set, we generated multivariate gait data classified as “gait rarely associated with stumbling” based on the input data. In addition, the generated multivariate gait data include motion that increases the thumb-to-ground distance and describe possible and natural gait considering the physical differences among individuals.

In recent years, the concept of value co-creation, which has expanded from value creation, has become widespread. Value co-creation is considered as a process of interaction between the provider's offering of a service and the recipient's consumption of the service. If receivers perceive positive emotions as a kind of value, the process of recognizing their value creation is a matter of Kansei or Kansei engineering. In this study, we attempted to describe an ontology in relation to Kansei value creation. Specifically, we conceptualized value creation and value capture as a type of design model, and specified the relationship between them and the design elements that compose the design model.

A head-mounted display with a head-tracking function enables the user to observe all directions of the field of view in response to the movement of the head, which results in a highly immersive image presentation. It is considered that an automobile driving simulator using this technology can reproduce more realistic driving behaviors without any discomfort than a conventional simulator that presents images on a planar display. In this study, we analyzed the effects of changes in driving posture on pedal operation, focusing on the accelerator and brake pedal operations.

There are two mechanisms of visual attention, which have different developmental processes. One is passive bottom-up attention and the other is active top-down attention. LED guide lights attract attention by the movement of light. Although such a bottom-up attention-grabbing display is intuitive, it has a disadvantage for constant use. In this study, we focused on the attention-inducing effect of the motion illusion to induce the illusion of motion in still images. The purpose of this study was to propose a display with high attention-getting effect by incorporating optical illusions. In this study, we used an illusory image of moving gratings to give the illusion of motion by placing black and white gratings in front of a gray background. To investigate the attention-inducing effects of illusory images, we conducted a visual search task with stimuli of illusory images that were not related to the task. In the visual search task, we tested whether the target in the upright disturbance was tilted to the left or right. As a result, we found that the optical illusion reduced the reaction time when guiding attention to the target. In addition, we measured the number of eye movements during the task and analyzed the number of gazes by using a gaze-measuring device. As a result, we found that the number of gazes decreased when the illusion induced the target's attention. The results suggest that the motion-induced optical illusion induces visual attention.

Various driver states are predicted during autonomous driving. Therefore, it is necessary to present information that can flexibly respond to behavior during autonomous driving. At that time, driver state estimation technology becomes important. In this research, we focused on the seat pressure sheet that can acquire the information only by sitting down. we measured seat pressure distribution using a driving simulator, and predicted driving behavior using a convolutional neural network. In this research, we predicted five driver states: "Forward gaze", "Cell phone use", "Distract (right)", "Sleeping", and "Distract (left)”. As a result, it was possible to predict with an accuracy of 78.8% in inter participant evaluation and 97.3% in overall evaluation.

The purpose of this study is to assess the interaction between walking and emotion variation. Two-dimension walking condition map and the two-dimension emotion map were used to understand their relation. According to the tendency of the changing walking gait in response to the emotion variation, we found that two factors can be influenced by each other. Therefore, by using this relation, we proposed an evaluation method for the user obtaining a better rehabilitation effect while using the assistive device. We recommended that the patient should walk comfortably through following the personal walking limitation, they thus can freely two-way control the emotion and walking while using an assistive device. To conclude, our proposed evaluation method can be employed for various assistive devices.

Light-emitting diodes (LEDs) are commonly used to backlight text indicators in vehicles, among other uses. It is desirable that such text indicators are both easily legible and have low fatigue-inducing qualities. Suitable spectral distributions for text presentation in vehicles have not yet been clarified. This study examined the legibility and fatigue experienced by participants when reading sentences presented through backlight emission for 10 min in a dark room. The backlight indicators employed both colored and white LEDs. The participants were asked to answer questionnaires to evaluate the LEDs’ legibility and fatigue. Moreover, the participants’ critical fusion frequency and brain activity were measured to objectively evaluate fatigue. The questionnaire results show that all of the colored backlighting displayed an almost equal legibility. The overall results suggest that participants were most (least) fatigued when viewing text illuminated by high color-rending (greenish white backlighting). Thus, fatigue can be reduced by using LEDs with different spectral distributions.

Fragrance influences the psychophysiological state of a person; the volume of fingertip plethysmography is consequently affected by the aspiration of aroma. In this study, stimulation threshold at the time of aroma suction and emotional change around the discrimination threshold were evaluated by analyzing both a questionnaire and fingertip plethysmograph measurement. We built a fragrance generator to confirm the stimulus threshold, discrimination threshold, and acclimatization time of smell. Participants were asked to take a subjective evaluation of aroma intensity, comfortableness (comfort/discomfort), and aroma frequency in real time. The results confirmed the chaotic nature of the time series data of the fingertip plethysmographs. Moreover, the fingertip plethysmographs fluctuated when the participants responded that it did not smell in the subjective evaluation and when the maximum Lyapunov exponent increased, as the aroma fluctuation of the fingertip plethysmographs enlarged, corresponding to the uncomfortable values of the subjective evaluation.

Recently, virtual reality (VR) has become a readily available technology owing to its compatibility with many devices and applications, such as head-mounted displays (HMDs). It is easy to experience an immersive virtual space by using an HMD. Generally, three-dimensional (3D) videos are considered to provide more realistic depictions compared to two-dimensional (2D) videos. Specifically, even for the same video, the influence on the viewer differs between the two viewing methods. However, depending on the type of emotion invoked in the person by the image, the realism is not necessarily important, so 3D is not always a more useful viewing method. We prepared similar 2D and 3D images and conducted experiments by measuring cerebral blood flow, sweating, heart rate variability, and conducting a questionnaire survey. Then, in the image providing soothing, it was found that 3D expression tended not to be favored.

Fragrance influences the psychophysiological state of a person as the volume of fingertip plethysmogram changes during one’s aspiration of aroma. Recent studies have used aroma in various settings, such as for medical care, relaxation, and productivity-enhancing environments. However, no study has elucidated the kind of behavior shown on the fingertip plethysmograph near the stimulation and discrimination threshold for the sense of smell when the odor intensity of aroma changes. Although our research suggests that emotions can be evaluated using the Lyapunov exponent of chaos analysis, no study has clarified the appropriate method for chaos analysis. Therefore, in this study, we performed a chaotic analysis of fingertip plethysmograms for evaluating emotional changes near the stimulation and discrimination thresholds during aroma inhalation. Results were evaluated using a correlation dimension and Lyapunov exponent. The optimal analysis method was examined thereafter.

At present, visually impaired people have difficulty using mobility support facilities due to their dependence on the surrounding environment, such as sound and snowfall. In addition, people who later became visually impaired may find it difficult to use these facilities. The current study aimed to develop an easy-to-use walking guidance system that uses three-dimensional (3D) sounds, regardless of the surrounding environment, and examined the characteristics of the guidance sounds produced by the 3D sounds. We implemented this system using a head-mounted display capable of generating three-dimensional sound. Participants were asked to walk in a visually restricted environment to either a real guidance sound or a 3D guidance sound with three types of ambient sounds, and their walking trajectory was evaluated. As a result, we found that the 3D guidance sound showed the opposite tendency to deflect from the ambient sound. However, the guidance accuracy of the 3D guidance sound was similar to that of the real guidance sound.

In this study, we aimed to examine the usefulness of gait classification and feature visualization based on multivariate data for the development of a gait feedback training system capable of considering the physical differences among the trainees. The multivariate data considered in this study were the joint angles and the ground reaction forces. In addition, all multivariate gait data were labeled as gait “rarely associated with stumbling” or “frequently associated with stumbling”. A convolutional neural network was used to learn the gait features. Furthermore, the feature parts of the multivariate gait data used for classification were visualized on a heat map created using Grad-CAM. As the results indicate, a heatmap is able to show the feature parts of a gait frequently associated with stumbling, through which the trainee can adjust their gait.

This study aimed to propose a display that incorporates the Fraser-Wilcox illusion with a higher attention effect. Fraser-Wilcox illusion is a type of visual illusion in which a part of a still image appears to be moving. We compared the attention effects of shapes that induce the Fraser-Wilcox illusion and those that do not. As an evaluation method of attention recall effect, the visual discrimination task, which was an experimental technique to measure the characteristics of visual attention, was used. The correlation between the strength of visual illusion and the target reaction time was examined. As a result, a strong negative correlation was observed. The larger the strength of visual illusion, the faster the detection of the target. These results suggest that the Fraser-Wilcox illusion has an alerting effect on visual illusion.

年次大会, 巻:2020, 号:0, 開始ページ:S12103, 2020年In recent years, composers are required to have a high level of understanding of musical equipment due to the diversification of equipment, and researches on musical instruments and timbre understanding support systems have been conducted. Some of the previous studies use the overtones of the instruments as features and support them with illustrations based on principal component analysis, but further investigation of the correspondence with the overtone parameters is needed. In this study, the similarity of the overtone components was calculated using the dynamic time warping method and illustrated by clustering and principal component analysis, and the correspondence between the parameters was discussed in detail. As a result, it was suggested that there may be a correspondence between the visualized figure and the fundamental frequency components in the middle and high frequency range.

年次大会, 巻:2020, 号:0, 開始ページ:S11526, 2020年In this study, we examine influence of difference in estimation method of point of gaze on evaluation of transparency during watching see-through vision. There are the two methods of estimating point of gaze, which are the method that uses the midpoint of the line segment that shows the shortest distance between the two lines of sight in three-dimensional space or the method of estimating it from intersection of two lines of sight on the two-dimensional plane. We compared these methods. As the result, there are significant differences in estimation error of convergence distance and there is relatively small variance in the three-dimensional point-of-gaze estimation methods. This result suggests that the three-dimensional point-of-gaze estimation method is more effective in evaluating transparency.

The olfactory brain that controls olfaction overlaps with the emotional brain that controls emotions, and is thought to have contributed greatly to the development of the emotional brain. Therefore, the sense of smell is considered to be more connected to emotions than other senses, and attention has been focused on manipulating the psychological state to a desirable state by using scent. However, it is thought that there is a gender difference in aroma. According to Oloveira et al., Women have a large number of neurons and neurons in the olfactory bulb, which play the role of receiving olfactory information, and women are superior in the smell separation test (1). Other studies have found that repeated exposure to odors increased olfactory sensitivity only in postpubertal women. From the previous case, it is considered that there is a gender difference in the intensity and type of emotion that occurs even when the same scent is presented. Therefore, in this study, we aimed to clarify the gender difference of psychological changes caused by scents.

This study aims to examine the relationship between visual fatigue and prefrontal cortex (PFC) activity during a backlit text reading task. We conducted a 10 min luminescent sentence reading task in a dark room. Time-course of oxy-Hb in the PFC was measured using a 22-channel wearable near-infrared spectroscope (NIRS). Subjective fatigue was assessed using the "Jikaku-sho shirabe" questionnaire. The critical flicker-fusion frequency (CFF) and LF/HF were assessed as objective index of fatigue and autonomic nervous system. 192 trials consisted of twelve healthy young volunteers and twelve LED treatments were analyzed. In the analysis, a linear non-gaussian acyclic (LiNGAM) model for causal discovery was introduced in addition to the correlation analysis. Our results suggested that the development of visual fatigue and central fatigue is related to the deactivation conditions in the medial PFC and Left PFC.

In the use environment of a mobility scooter, there may be many obstacles that need to be avoided, such as pedestrians on a narrow sidewalk or cars on the edge of the road. These obstacles not only interfere with smooth driving but also induce mental strain on the user such as fear and anxiety, which may cause a decrease in comfort and an accident. The purpose of this study is to estimate physical obstacles in the road environment when driving a mobility scooter from operation information and physiological information of the user obtained during driving. We measured skin conductance, manipulation amount of accelerator, steering torque, and acceleration value in the horizontal plane when driving on a few courses with physical obstacles. We tried to build a machine learning model that estimates the type of physical obstacles in the course based on these time-series data by using a random forest classifier.

日本機械学会論文集, 巻:86, 号:890, 開始ページ:20, 終了ページ:00034-20-00034, 2020年This study aims to examine the benefit of visual fatigue evaluation based on prefrontal cortex (PFC) measurement by near infrared spectroscopy (NIRS), and to evaluate fatigue on various colored LED backlit text. In our method, eight adult participants read a LED backlit text 10 minutes in a dark room. Before and after task, subjective fatigue questionnaire "Jikaku-sho shirabe", subjective visual fatigue questionnaire (SVF), and the critical flicker-fusion frequency (CFF) were measured. The time-course of oxy-Hb in the PFC was measured using a 22-channel NIRS. Heart rate variability (HRV) was measured to access an autonomic nervous system balance. Six types of white LEDs were used for backlighting: general white as a control (W), high color-rendering white (WH), bluish white (WB), reddish white (WR), greenish white (WG), and yellowish white (WY). In our results, correlation analysis suggested that the development of central fatigue is related to deactivated condition in the mPFC, and the development of subjective visual fatigue is related to deactivated condition in the LPFC. In comparison between LED treatments, in WH condition, high subjective central fatigue, CFF decay and LF/HF were revealed, and the PFC inactivated. In WG condition, low subjective central fatigue and CFF decay revealed. Our findings suggested that participants get tired on high color-rendering white LED backlit text, and were less tired in greenish white LED backlit text. Also, NIRS provides benefits in the evaluation of visual fatigue.

Obesity would be a cause of many diseases such as hypertension, dyslipidemia and diabetes. Considering obesity, we examined satiety closely related to energy intake. In this study, we focused on the number of chews and chewing frequency, which are factors of satiety, and analyzed the influence on it. In the experiment, we compared satiety, hunger and masticatory muscle activity among the conditions when participants ate the same amount of food under the condition that the number of chews and the chewing frequency were changed. As a result, the datas of the increase rate of satiety and the masticatory muscle activity showed that participants of low weight and normal weight who consumed foods by chewing many times, and participants of obesity who consumed foods with large masticatory muscle activity for each chew could feel fullness earlier. Using this result, people can reduce the energy intake naturally by feeling fullness early in the diet, and it is expected to improve the eating habits of obese people.

設計工学・システム部門講演会講演論文集, 巻:2019, 号:0, 開始ページ:2404, 終了ページ:2404, 2019年In recent years, new indicators focusing on cognitive activities have been developed for the purpose of improving the accuracy of lie detection tests. It has been pointed out that eye movement is particularly effective. In addition, there have been many reports of lie detection based on gaze movements and blinks. But these indicators are greatly influenced by human intentional control. In this study, we focus on the pupil diameter, which is difficult for humans to control intentionally. we verify whether it can be used a new index of lie detection method. In this experiment, we analyzed changes in pupil diameter when presenting a critical question and a non-critical question in a CIT issue. As a result, when the pupil diameter was dilated at the time of question presentation, the pupil diameter at the time of presentation of the critical question was smaller than that at the time of non-critical question presentation. This is because the cognitive load is suppressed by making the participants unaware of the contents when the critical question is presented. This result suggests that the pupil diameter can be used as a new index in the lie detection method.

設計工学・システム部門講演会講演論文集, 巻:2019, 号:0, 開始ページ:2402, 終了ページ:2402, 2019年When Fragrance influences the psychophysiological state of a person, and consequently the volume of fingertip plethysmography is affected by the aspiration of the aroma. Recently, studies have attempted to employ aroma in various scenarios, such as in smells for medical care, relaxation, environment improvement for productivity enhancement, and others. However, the type of fingertip plethysmograph behavior produced near the stimulation threshold that allows feeling the smell remains unclear, especially near the discrimination threshold, where fragrance intensity changes. In this study, the stimulation threshold at the time of aroma suction and the emotional change around the discrimination threshold are evaluated by analyzing both a questionnaire and fingertip plethysmograph measurement. As human biological systems produce chaotic behaviors such as heart beat rhythms and the plethysmograph, chaotic time series analysis was performed for fingertip plethysmograph measurements. Then, we evaluated psychophysiological responses during aroma suction, using a feature of the chaotic behavior in fingertip plethysmograph. In addition, we analyzed and compared with the conventional method LF / HF. As a result, we confirmed the fluctuation in the fingertip plethysmograph even when the research participants responded that it did not smell in the subjective evaluation. Further, we confirmed the fluctuating tendency of the fingertip plethysmographs when the Largest Lyapunov exponent increased as the aroma hen the maximum Lyapunov exponent increased as the aroma the fluctuation of the fingertip plethysmographs becomes large and corresponds to the uncomfortable values in from the subjective evaluation. In addition, the relaxing effect by smell was confirmed using LF / HF.

We used machine learning to extract features related to cognitive load in any brain region and time domain of oxy-Hb measured by NIRS. We conducted a 5min auditory stroop task. Ten healthy young volunteers participated in this study and performed five repeated experiments. The brain function in the prefrontal cortex was measured using 22ch wearable near-infrared spectroscopy. Cognitive load was assessed using questionnaire surveys NASA-TLX and accuracy. The results of analysis using neural network (NN) and layer-wise relevance propagation (LRP) suggest that around the inferior frontal gyrus (IFG) contain important features for classifying cognitive load, and oxy-Hb in IFG may increase with cognitive load. Our LRP method can extract common features to oxy-Hb within the same group, visualize the effect of cognitive load on individual data.

When we conducted to train models, we calculated model accuracy by 5-fold cross validation in each condition. As a result, the accuracy rate increased as input image size increased in 3 conditions (50×50 px, 100×100 px, 200×200 px). However, the accuracy rate of the model trained by 4 conditions (700×700 px, 800×800 px, 900×900 px, 1000×1000 px) were lower than that trained by other conditions. These results are thought to be caused by setting the kernel size to the same value in all conditions. Therefore, we concluded that it is necessary to determine an appropriate kernel size and stride for each input image size which can extracted features included in the input image when we conduct to generate a model for the purpose of distinguish between cancer cells and normal cells in the large intestine.

In order to provide appropriate support, a method that driver behavior prediction has been proposed. In this research, we measured seat pressure distribution and driving information using a driving simulator, and predicted driving behavior using a convolutional neural network. In this research, we predicted five driving behaviors: "Go straight ahead", "Turn right", "Turn left", "right lane change", and "left lane change". As a result, it was possible to predict with an accuracy of 65.4% in inter participant evaluation and 96.4% in overall evaluation.

The main chemical substance in tobacco smoke is nicotine. We decided to build up a model first for nicotine. In this study, we use a newly developing gas analyzer which measures nicotine in real-time. From that nicotine measurement result, analyzes the nicotine behavior with FEM in a simulated space. Then make it learn the parameters of the nicotine behavior model, and using a different modeling and learning algorithm than general multi-agent reinforcement learning, we visualize the nicotine behavior in tobacco smoke through the new achieving model. First, we confirmed the availability of nicotine analysis with the gas analyzer.

年次大会, 巻:2019, 号:0, 開始ページ:S12103P, 2019年The purpose of this study is to clarify feature for discriminating emotion while expressing fake smile. First, we experimented to record face expression in video. The flow of the experiment was following; we first displayed one of emotion-eliciting films, and participant expressed (fake) smile just after watching the film. At the end of the experiment, we let them assess what emotion they felt with two self-report measures. We prepared six emotion-eliciting films in order to record various face expression with various emotion. Then, we obtained face landmark positions from the face on the recorded video using a method proposed by Kazemi et al(1). We focused that eyes and mouth corners move well while smiling, and defined 15 feature values related to that landmarks. Furthermore, we grouped the feature values in emotion scores by clustering. There are significant differences in eye area between happiness and disgust, and in some mouth corners' feature values between happiness and fear as a result of comparison of clusters. we considered these differences resulted from disgust/fear, but negative emotion.

年次大会, 巻:2019, 号:0, 開始ページ:S11114, 2019年The caution making is used in various daily situations as a preventive measure of tumble accident which is one of the labor accidents. The purpose of this study is to propose a display that incorporates the Fraser-Wilcox illusion and has a higher attention effect. Fraser-Wilcox illusion is a type of visual illusion in which a part of a still image appears to be moving. We compare the attention effects of shapes that induce the Fraser-Wilcox illusion and those that do not. As an evaluation method of attention recall effect, the pre-cueing task which was an experimental technique to measure the characteristics of visual attention was used. The correlation between the amount of visual illusion and the target reaction time was examined. As a result, a strong negative correlation was observed. The larger the amount of visual illusion, the faster the detection of the target. These results suggest that the Fraser-Wilcox illusion has an alerting effect on visual illusion.

年次大会, 巻:2019, 号:0, 開始ページ:S11103, 2019年The purpose of this study is to estimate the condition of second-hand goods from images using machine learning methods. Assuming that the condition evaluation of second-hand goods has a relationship with the damage that exists in them, we proposed and verified a method to estimate the condition of second-hand goods based on information of the damage. In this study, we chose men's dress shoes for condition evaluation and chose four types of damage: wrinkles, worn out of heel, dirt on outsole, dirt on inside as damage considered to be related to condition evaluation. (1)We create a CNN model that determines the presence or absence of damage, and (2) create a classification tree model that evaluates the state of the product from information on the presence or absence of damage and (3)We evaluated the condition of second-hand goods by combining two created models. As a result of verification, it was shown that the proposed method could evaluate the condition of used goods.

In this research, we focus on the driver's immersion in typing with a personal computer during automatic driving. We examined changes in driving operation after switching to manual operation when the warning sound is presented under four conditions including two conditions of beep sound and two conditions of presentation voice. The beeper was able to react quickly but it was found to be dangerous for driving operations. In voice presentation, it was suggested that a warning simply presented could not assist appropriately but presenting hazard avoidance instruction enabled quick reaction and assisted in calm driving behavior.

Currently, the visually impaired find it difficult to use mobility support facilities because they depend on ambient environment such as ambient sound and snow cover. Further, people who acquired visual impairment in the later stages of life also find it difficult to use these facilities. Therefore, in this study, we aimed to develop a walking guidance system using 3D sounds that will not be influenced by the surrounding environment and will be easy to use. Further, we verified the induction effect in the blindfold state and the ambient sound. This system was implemented with a head mount display that is capable of producing 3D sound. Under a visual restriction environment, blindfolded participants were asked to walk toward a real or 3D guiding sound with three types of ambient sounds, and then, we measured the walking locus. We found that the 3D sound tends to provide veering tendency opposite of the ambient sound. However, the guiding accuracy of the 3D sound is similar to that of real sound.

There have been several recent attempts to aid car drivers by providing information on internal and external car environments. The optimal amount of information must be determined to avoid confusion. In this study, the "Stroop task" was used for information processing, and the cognitive load was gradually increased by adding information in stages. We designed and conducted two tasks that originate in the "Stroop task"; these two tasks feature significant differences in cognitive load. We also measured brain activity using near-infrared spectroscopy (NIRS) under the assumption that such activity can be used as an index of cognitive load. Both tasks were associated with increased oxy-hemoglobin levels in the prefrontal area, and the task with a higher cognitive load was associated with a more substantial increase in oxy-hemoglobin; this indicates that oxy-hemoglobin levels may be used as an objective index for the evaluation of information-associated cognitive load.

To examine brain areas related to the cognitive load condition during the Stroop task, we proposed a method using a Deep Neural Network (DNN). We acquired cerebral blood flow data in congruent and incongruent tasks by near-infrared spectroscopy (NIRS) equipped with 22 ch. The data were used to train a DNN, and the influence of each factor on the output was evaluated. Our DNN model consists of independent input layers for each channel of NIRS, as well as fully-connected hidden layers and output layers. Our results suggest that the medial prefrontal cortex (focusing on cognition) and the left inferior frontal gyrus (focusing on language processing) were involved in the cognitive load during the Stroop task. These results in the Stroop task were consistent. Therefore, the proposed method's utility was confirmed.

Emotion is an internal and subjective experience that plays a significant role in human life. There are several methods of recognizing emotions in people, the most authentic of which is using physiological signals, as they are beyond one's control and strongly correlated with human emotions. This study aims to develop an emotion recognition system based on three physiological signals, namely, brainwave, heartbeat, and facial muscular activity. It utilizes deep neural network (DNN) and the T method of Mahalanobis-Taguchi system (MTS) to process the multiple physiological signals and further recognize the states of human emotion. As such, nine emotions are effectively recognized on a two-dimensional model through the DNN, then compared against several other algorithms, such as MTS, SVM, Naive Bayes, and K-means, where its superior accuracy is validated. Moreover, although the T method only improves the classification accuracy on the valence state, it rather obtains the intensity of emotion in different states. Furthermore, in this study, the proposed DNN is implemented into a wide range of applications for an accurate understanding of the human emotional states, whereas the T method is utilized to respond to the emotional intensity in different states. Finally, a real-time emotion recognition system is developed with DNN as the classifier; this system can directly monitor the variation of the human emotion through reliable and objective emotion analysis results from the physiological signals. Thus, the method can provide useful treatment effect information for robots or assistive apparatus serving activities of daily living.

The authors' goal is to develop brakes that are more satisfying to users in sensory aspects by explaining the relationship between people's state of mind and a vehicle's physical quantities. However, there are no scales to measure such feeling. In this study, a psychological scale was constructed to measure the affective state of general automobile drivers, for the purpose of clarifying the effects of brake characteristics on the affective state. To construct the affective scale, two experiments were conducted. In the first experiment, a comparison of four types of vehicles was performed and then an interview survey was conducted to collect a broad sample of terms used to evaluate the affective state. From the results, it was hypothesized that the evaluation terms were divided into eight categories. For each hypothesized category, ten evaluation terms were selected from the terms obtained in the interviews, the items of the existing psychological evaluation scale, and the synonym survey results of them. In the second experiment, we evaluated terms we selected to conduct an assessment of 15 types of driving scenarios that were selected from among brake evaluation patterns. Next, we conducted a factor analysis using the assessment results. As a result, the affective states were classified according to seven factors (Well-Being, Anxiety and Surprise, Liveliness, Positive Feelings, Disgust, Boredom, and Concentration), with five items attached to each factor, yielding a total of 35 items. The reliability and the validity of each scale were investigated. Results have shown that the subscales have highly internal consistency and factorial validity.

This chapter presents authors development work on walking assistant exoskeletons for gait training of patients and promotion exercise of the elderly. The first exoskeleton is a whole leg assisting device using a special parallel link mechanism. For gait training of motor palsy patients, a weight bearing lifter was attached, and an impedance control was tuned by using frequency entertainment. For the elderly, a torque controller taken into account the dynamics of both a user and the apparatus with real time acceleration data is developed. The second exoskeleton is a whole body assisting suit was developed by adding arm assistance to the whole leg apparatus. By assisting not only legs but also swinging arms, an increased cerebral activity of all areas can be expected via rehabilitation with the whole body exoskeleton. Finally, we developed a close-fitting type exoskeleton assisting only ankle joint, which leads to a product RE-Gait® in 2016. By utilizing the structure of bi-articular muscle and physiological phenomenon of stretch reflex, the user’s leg can be raised assisting only ankle joint. Experiments with by hemiplegic patients are enclosed, which show that abduct variation of the hip joint is decreased while the stride length is increased by using the device.

In this paper, we evaluated the mental stress recorded against corner entry speed while riding a mobility scooter by measuring skin conductance. A mobility scooter is a four-wheel electric wheelchair with a steering handle. These scooters, known as “Senior Car” are generally sold to the elderly. Some of these scooters have a system that automatically decelerates to approximately 70% of the maximum speed depending on the steering angle at corners. The preset deceleration rate can cause discomfort to the driver. To provide appropriate assistance without any discomfort, evaluating the mental stress of the driver is necessary. Skin conductance (SC) is one method for measuring sweating. It can measure mental sweating related to sympathetic nerve activity. We modified a commercially available mobility scooter to be used as an experimental wheelchair such that it can be controlled using a PC. We measured SC in a task that involved turning right into a corner at a constant speed using an experimental wheelchair and tried to evaluate the mental stress against the corner entry speed. Resultantly, a positive correlation between the amplitude of SC and entry speed was obtained. In addition, we performed a questionnaire to evaluate the ride discomfort after the experimental task. The questionnaire results demonstrate that the evaluation value of the items “No Fear” and “Safety” decreased as the speed increases. This result was consistent with the measurement results of the SC amplitude. From these results, we conclude that fear against corner entry speed could be evaluated using SC.

In recent times, robots such as, service, communication, and cooperative robots, have been developed to assist humans in various tasks. Smooth communication is an important parameter to ensure appropriate assistance by robots. In communication, understanding the comprehension status of the partner leads to an easy-to-understand explanation. However, it is difficult to accurately understand the comprehension status of the partner. The purpose of this study is to clarify the relationship between thinking status and pupil size and blink rate. Word association tasks were conducted, wherein subjects associated a theme from five auditory words. Pupil size and blink rate were measured during the task using gaze measurement. The result showed that pupil size tended to increase during thinking and decrease with association. Decrease in blink rate distribution was observed after presentation of a word, following which a temporary peak occurred before association. However, no change in blink rate was observed after the association. Based on the results of the present study, it was revealed that thinking may be associated with pupil size and blink rate, and it can be suggested that the eye could be an index to evaluate thinking status.

In addition, this study included two groups (Group A and B) of patients who undertook the tasks. Based on the timing and the number of mistakes, it was observed that subjects in group A demonstrated lesser information processing ability than those in group B. The findings of the present study thus indicate that oxy-hemoglobin variation may depend on the information processing ability of the subject.

It is important to mesure energy metabolism for human health. Current mainstream activity meters show large inaccuracies in the estimation of energy metabolism for small mothion. In this study, we examined the estimation method of energy metabolism during exercise with small motion by using electromyography and heart rate, both of which are correlated with energy metabolism. We chose wrist curl a type muscular strength training to represent movement with small motion, and considered the flexor carpi radials and biceps brachii as target muscles. Multiple regression analysis was used to estimate energy metabolism; this allowed us to estimate that there is an error of about 25% when estimating total energy metabolism. Although comparison was carried out at ten-second intervals, estimation was difficult because of the large variation of experiment values. This study suggests that total energy metabolism during exercise with small motion can be estimated by using myoelectric potentials and heart rate.

At nursing care sites, patients undergo an exercise regimen as rehabilitation and training for walking disorders. However, it is presumed that their motivation decreases over time because in a nursing home, walking exercises are performed in a closed space and are repetitions of monotonous movements. Therefore, it is necessary to develop a more varied and effective rehabilitation or training method. The purpose of this study is to develop a varied and effective training method wherein the trainee walks while viewing virtual reality (VR) images. Specifically, in the proposed method, the trainee views VR images of walking on a slope, while actually walking on a treadmill, and he/she controls the physical load. In this study, we conducted an experiment using a composed training system with the aim of analyzing the influence of watching VR imagery of walking on a slope on the braking and driving forces while walking on a horizontal treadmill. We improved the VR system to automatically adjust the treadmill speed from the position information of the trainee. Then, comparative experiments of the braking and driving forces were performed for cases of walking while watching images of level and slope grounds. As a result, the walking speed, braking force, and driving force tended to decrease when watching downward slope images compared to watching level ground images. Additionally, the walking speed, braking force, and driving force tended to increase when viewing upward slope images.

Students in many universities, technical colleges, and technical high schools are practicing their cutting skills using general-purpose machining tools. However, there may be insufficient guidance due to the lack of the number of instructors and a limitation on the number of general-purpose machining tools that they can use. In this research, we propose a system to support the learning of cutting skills using a virtual reality head-mounted display. Preparing students to use machining tools require many training sessions, especially for cutting using a general-purpose lathe. A user can experience three types of content: drawing, tools, and the general-purpose lathe. This learning system was provided to seventeen students, and we conducted a questionnaire on its ease of understanding, appearance, enjoyability, intuitiveness, and operability. Resultantly, enjoyability and intuitiveness were highly evaluated. The results suggest that our proposed system can be used as a learning method. To improve the operability of the VR system, we can make use of specialized controllers or additional force presentation devices.

年次大会, 巻:2018, 号:0, 開始ページ:S1210204, 2018年It is generally agreed that the risk of falling increases with age. Falls in elderly individuals decrease their daily life activity level due to physical damage and increase fear of falling again. It is proposed that many elderly falls occur when walking, and in most, the cause is stumbling. Therefore, the aim of this study was to analyze the factors of stumbling during normal walking to prevent falls. Then we determined the thumb-floor distance, the angle of lower limb joints and the ground reaction forces. Furthermore, we calculated the moments of the lower limb joints from the obtained results. And compared these values during normal walking between elderly group and young group. Consequently, a significant positive correlation was found between the maximum value of the longitudinal component of ground reaction force and the maximum value of thumb-floor distance at terminal swing. Furthermore, when the longitudinal component of ground reaction force was the maximum, the hip flection moment of the elderly group was significantly lower than young group. These results showed that the cause of the fall of elderly is that the driving force at terminal stance is weak due to weak hip flexion muscles and that the knee joint is not sufficiently extended at terminal swing.

年次大会, 巻:2018, 号:0, 開始ページ:S1210203, 2018年In recent years, it is required to design a notification sound which is easy to hear even in the daily life sound. It is necessary for the notification sound to use sound of frequency below 2000 Hz that the elderly can hear easily. Therefore, in this research, we aimed to evaluate how the influence on the recognition and impression of the notification sound is caused by the difference in the timbre. In this experiment, the participants heard three kinds of timbre of sine wave, rectangular wave and sawtooth wave. The threshold of listening sound pressure level was measured, and the questionnaire to evaluate impression of notification sound by semantic difference method was conducted. As a result, we found that the sine wave is familiar and does not give much tension or discomfort. In addition, we found that the rectangular wave and the sawtooth wave are less familiar and give a sense of urgency and discomfort. It was suggested that by changing the timbre of the notification sound, it is possible to design a notification sound that the intention is more easily heard and accurately transmitted.

年次大会, 巻:2018, 号:0, 開始ページ:S1210202, 2018年Demand for vital sign measurement systems have been increasing. Non-invasive systems are required that it can monitor health status over a prolonged period. Conventional devices can easily measure pulses. However, as the noise due to perspiration is superimposed on the waveform of the pulse, the peak of the pulse becomes unclear, so it is unsuitable for measurement for a long time. In this study, we devised a pulse measurement method that can deal with the above problem. We obtained the acceleration waveform from the carotid artery skin surface, using the acceleration sensor. These waveforms are pulse waves caused by the expansion and contraction of the carotid artery. By the measurement procedure that they devised, six of ten people were able to be measured the pulse. In addition, it became possible to measure the pulse by other four people straightening the neck and attached the sensor to the appropriate position carefully.

年次大会, 巻:2018, 号:0, 開始ページ:S1110605, 2018年In recent years, various researches on abnormality detection using machine learning have been conducted. However, when an abnormality is detected, it is necessary for engineers to find the cause of the abnormality and deal with it. If it is possible to estimate the cause of the abnormality at the time of detection, engineers can prepare appropriate repair tools and replacement parts. Machine downtime can be shorten by this estimation. In this research, we proposed new method and conducted experiment to verify its usefulness. In the proposal method, we use convolution neural network (CNN) to detect an abnormality and estimation a cause of it. Operating sound and current value were used for input. In the experiment, we chose geared motors as a model of a rotating machinery, and we used proposed method to them. As a result, we got an average accuracy rate of 82.41% on detection of abnormality, and also got average accuracy 67.84% on cause estimation of it. From these results, it was shown that the proposed method is effective for detection of abnormality and cause estimation of it for rotating machinery.

年次大会, 巻:2018, 号:0, 開始ページ:S1110501, 2018年In recent years, it has been said that the number of mastication and mealtime tends to decrease with the spread of fast foods and softening of foods. Decrease in the number of mastication causes many problems such as obesity, shrinkage of the jaw, loss of natural teeth. In this study, we examined a method to increase the number of mastication by changing the subjective texture of food by presenting mastication sound with bone conduction headphones when chewing food, based on a cross-modal. Moreover, we investigated what kind of mastication sound is effective for increasing the number of mastication from the viewpoint of texture. The result showed that there was a possibility of increasing the number of mastication. On the other hand, a certain result was not obtained with regard to the texture, because the texture which has the correlation with the number of mastication was different depending on the food. However, as the result of a questionnaire of the texture, the correlation between the texture of heavy and the number of mastication was found. Therefore, we confirmed the possibility of increasing the number of mastication by controlling the subjective heaviness of food.

年次大会, 巻:2018, 号:0, 開始ページ:S1110104, 2018年In recent years, cognitive support research has been conducted to reducing the number of traffic accidents. There is a possibility of confusing the driver if the cognitive support is not appropriate. Therefore, there is a need for a method to support driver's perception of dangerous objects without hindering normal driving behavior. In this study, we measured driving behavior and cerebral blood flow when moving sound was used as cognitive support. By using the moving sound as the cognitive support, the brake operation at the time of avoiding the danger became moderate. From the results of cerebral blood flow, it was found that information can be transmitted with the same cognitive load as in normal operation. As a result, the possibility that the moving sound can appropriately assist perception of the surroundings of the driver has been shown.

The purpose of the current study is to evaluate fatigue reduction characteristics in LEDs luminescent text display. For this purpose, we construct a model to estimate the participant's fatigue from physiological index. In the experiment, participants read Japanese sentences that were represented by backlight emitting for ten minutes. Brain activity were measured for the physiological index, and fatigue evaluation questionnaire was answered. The luminescent text display was implemented with LEDs of six kinds of white color. We constructed the deep learning model that inputs brain activity, and outputs "fatigue", "no fatigue" or "no change". The output was calculated from fatigue evaluation questionnaire. The model was able to estimate the fatigue with a validation accuracy of 86.4 %. Thus, the model showed the possibility that estimate fatigue based on the brain activity.

In this study, we measured brain activity using near-infrared spectroscopy (NIRS) when a person was feeling discomfort caused by vibrations. We used the variance in oxygenated hemoglobin (oxy-Hb) levels as an evaluation index. Correlation coefficients were derived from the results of brain function measurements and sensibility evaluation of discomfort using a questionnaire. As a result, a high negative correlation was observed between discomfort and both vibration and brain activation around the medial prefrontal cortex, and a high positive correlation was observed between discomfort and both vibration and brain activation around the lateral prefrontal cortex. This suggests the possibility of evaluating discomfort on the basis of brain activation.

In recent times, light-emitting diode (LED) lighting has been widespread in offices and manufacturing buildings, but for assembly operation in manufacturing situations, it has not yet been explored. In this study, we measure color preference and visual fatigue to evaluate LED task lighting for assembly operation. We conducted an experiment to obtain subjective responses to color preference and to measure visual fatigue under LED lighting. The participants were asked to assemble a gearbox model as a task under three different lighting conditions. As a result, lighting with high color temperature was rated with high visibility, fatigability, and low preference. On the other hand, critical fusion frequency, which indicates visual fatigue, was higher in lighting with low color temperature than in lighting with other conditions. This indicates that color preference as a subjective response discords from visual fatigue evaluated by biological information.

With the ongoing development of information and communications technology, it is apparent that computers will be indispensable partners in future human life. In terms of computer information processing, techniques for coordinating human sensitivity and emotional levels are attracting attention and stand in contrast to conventional knowledge information processing. In this chapter, we present an overview of content-oriented research considering knowledge itself and describe an approach to handling knowledge of human sensitivity and emotions using computers. First, we provide an overview of existing content-oriented studies in the field of artificial intelligence (AI). Second, we discuss problems regarding the handling of knowledge of human sensibilities and emotions. Then, we introduce an ontology pertaining to the concept of color emotion as an approach to understanding human sensibilities and emotions. Finally, we describe the applicability of such an ontology to human-computer interactions and for the understanding of human nature through the concept of analysis-by-synthesis.

Journal of Advanced Mechanical Design, Systems and Manufacturing, 巻:11, 号:6, 2017年11月
Due to the growing elderly population in many developed countries like Japan, assistive devices are increasingly needed to overcome the difficulties of their activities of daily living (ADL). The motion of standing up places a particular burden on the ankle and knee joints and connects static motions (e.g., sitting and lying) and kinetic motions (e.g., walking and climbing up/down the stairs). In our previous research, two types of standing-up assistance apparatuses were introduced according to the suitable standing-up motions. However, these devices are bulky and cannot be widely used in practical settings such as bus terminals. Regarding the suitable standing-up motions of the elderly in the previous literature, a standing-up apparatus with a pantograph mechanism is introduced to diminish the size of the mechanism based on three design principles: (1) the trajectory of the user's COG is an arc; (2) the trajectory of the user's hip joint while standing up is a straight line at an angle of 45 [deg] from the horizon; and (3) the user is supported until the knee angle reaches 60 [deg]. Simulations showed that the load on knee and ankle joint is decreased, and user may stand up easily with our proposed apparatus. A prototype of the apparatus that may be installed on various chairs in public was fabricated. Considering that the apparatus may be used in places without electric power supply, the apparatus is made simply with links and a gas spring instead of electric actuators. Experimental measurements of the trajectories of the center of gravity (COG) and hip joints show that the proposed apparatus may help users to stand in a way that minimizes stress on their lower-body joints.

The Proceedings of the JSME international conference on motion and power transmissions, 巻:2017, 開始ページ:12, 終了ページ:2, 2017年A walking assistance apparatus using a torque limiter was developed. We used the servo motor for hobby, it is relatively small, light weight, and included not only a motor and transmission gear, but also a driver and encoder. At first, we controlled the device using angle control method, according to the walking phase along to the mean data of able bodied people while walking. However, when the user stops walking suddenly or walk on outdoor various roads, the final gear was broken frequently. Because the gear was designed to break easily, to defend the motor from the inverse inputting overload torque. Then we developed a torque limiter mechanism in the final gear. This is a traction drive sandwiched a soft material plate between two circular disk. We carried out the experiment to measure the limit torques of eight kinds of the rubber material. In this paper, the results of the experiment were shown.

The Proceedings of the JSME international conference on motion and power transmissions, 巻:2017, 開始ページ:12, 終了ページ:1, 2017年We developed small type of a standing up device for the elderly. We have developed standing up devices; caster walker type and bed wheel chair type. They assist standing up motion, backed on following two conditions. 1) the trajectory of center of gravity of the user is round shape, 2) the trajectory of the hip joint of the user while standing up is straight line. These conditions were found from the data of able bodied elderly people, and the feature of their standing up conditions is to lean forward the upper body. By using these devices, the load of the knee joint decrease, and the user can learn how to stand up easily. However, these devices are bulky and usable scenes are limited. Then we developed small type, which can be used on various chairs. This type assists from sitting posture to the middle phase while standing up. The mechanism is constituted with links and a gas spring, instead of a motor. It is light weight, low cost, and small to be able to attach to the back of a chair. From the calculation, by using this new type, the output torques of the knee and ankle joints decreased.

設計工学, 2017年We developed a new power assistance suit without the need for electricity. This suit is to support care worker's assistance behavior, e.g. lifting-up and holding motion. It is made of only rubber and nylon belts. This suit can assist the equipped person's arms and back with two kinds of equipped belts. One is for the waist, attached from the shoulder to the back of the knee via his/her back. The other is for the arms, attached from equipped person's forearm to the back of the knee via his/her back. To confirm the possibility of this suit, first, we interviewed medical doctors and physical therapists. Their comments were, it is important to adjust the length of each belt for an equipped person adequately, and it is effective for the assistance of motion in a half-sitting posture and in transfer motions between a bed and a wheel chair. Furthermore, we measured the variation of maximum output force and %MVC of the entire body muscles during lifting and holding motions using the suit and not. From the result, by using this suit, the maximum lifting weight of the equipped person was increased by over 8kg, and the arms and back of the equipped person were assisted effectively.

In recent years, with the development of IoT technologies, biological information of users has been easily acquired and accumulated. It is required that user's cognitive or emotional state could be accurately identified from such biological information. Various researches have used machine learning or deep learning however, generalized methods to handle biological data have not been established. In this paper, we propose a more versatile method using convolution neural network of deep learning to extract features from individual biometric information which is multi-channels time-series data representing user’s cognitive. We demonstrate a new method of extraction and distinguishment of features from cerebral blood flow, skin temperature, respiration and skin conductance measured during specific task conditions in the stroop experiment.

Recently, the viewpoint of service has become widespread. In learning domains, service providers have been required to adopt the viewpoint and to provide values co-created by teachers and learners. However, production by a service provider means the generation of potential value, whereas usage by a service receiver implies the generation of real value. That is, a receiver creates value independent of the value generated by a provider. Indeed, value co-creation takes place in a joint sphere where providers and customers interact with each other. Thus, service providers must attempt to generate the potential value through service design and play a role of co-producer of the real value in the interactions between the providers and the receivers. In the current study, we developed an ontology to share the knowledge on value co-creation and the information related to the interactions between the providers and the receivers. In concrete terms, we proposed ontological descriptions of receiver states for sharing knowledge in learning service design, and conceptualized elements of consensus building and value co-creation, according to the conceptual model of value co-creation proposed in a previous study. In addition, concepts pertaining to academic emotions are also described to represent contents of consensus building. Then, we demonstrated instances of a consensus building, which is extracted from conversations during counseling by a teacher (mentor) and a learner. As a result, we obtained a metamodel for co-design processes in the learning service design, and a conceptual framework of the knowledge sharing on learning states including academic emotions by the ontological descriptions.

We proposed a method that promotes walking which uses a two-dimensional emotion map. In this method, a subject listened to a beat sound while walking. The beat was adjusted according to the condition of the subject, based on his/her comfortable walking frequency. Simultaneously, the walking velocity, the stride length, and the heart beat of the subject while walking was measured, and LF/HF was calculated from the result of measured heart beat. Furthermore, we asked them to give information on the condition of their feelings, from pleasant or not by 5 levels in each case of the beat sound. By using these data, a two-dimensional walking condition map and two-dimensional emotion map were made and we found the relation between these two maps. Therefore, according to the emotional condition of the targeted person while walking, this method can promote or restrain walking adequately, only adjusting the beat sound.

In the current study, we formulated ontological descriptions for emotional states of users using motion assistance apparatus. In our previous studies, we developed apparatus that assists the ankle joints of patients in neuro-rehabilitation. Although we have confirmed the apparatus can improve the gait of the patient while walking, we have to capture and manage patients’ emotions as feedback of the usage. The ontological descriptions provide a feasible framework for common understanding while sharing and using this knowledge. In future work, we will develop a subset of this framework for more practical usage, in addition to expanding the descriptions of emotional states. After that, we will assess the validity and utility for design and implementation of software and hardware applications using this subset.

年次大会, 巻:2017, 号:0, 開始ページ:S1150105, 2017年The increase in the aging population is one of the common problems in the world. Many elderly people experience difficulty in standing up from their seats owing to muscular depression. To improve the QOL (Quality of Life) and ADL (Activities of Daily Living) of elderly people, improvement of the traffic environment is necessary. We developed an assistive seat to help elderly people rise from their seats in a bus with fewer loads. We verified the performance of the assistive seat through EMG analysis. In conclusion, the developed assistive bus seat was effective in helping the user to stand up without difficulty.

年次大会, 巻:2017, 号:0, 開始ページ:S1150206, 2017年It is difficult for users of electric wheelchair who suffer from quadriplegia or have compromised motor skills to manipulation of the joystick finely. Also, there is a risk causing a loss of control upon impacts with steps. In this research, we design a system that performs to assist fine control of the speed depending on the height of the step. This system uses a laser range finder to detect the step from remotely, and uses the valuation of human exposure to whole-body vibration in order to estimate discomfort that arose from the step height and step climbing speed. The potential of this system is also verified and manifested to reduce the impact caused by collisions with steps.

年次大会, 巻:2017, 号:0, 開始ページ:S1150205, 2017年Currently, Japan is entering a super aging society, and as the population of elderly people increases, the number of care recipients are also on the rise. The burden on nursing care homes is increasing; specifically, the burden on caregivers in excretion assistance is huge. Therefore, the need to develop nursing care equipment to support such tasks is increasing. In this study, a preliminary investigation was conducted to determine the possibility of excretion time prediction using data from the diet of a care recipient. We requested and obtained meal data and excretion data from experiment collaborators. We attempted to design a system that predicts the excretion time by a process similar to machine learning using a neural network that corresponds to the two sets of data. We can roughly predict the excretion time. The result showed that it is possible to predict the excretion time from the meal record. In the future, we will include details of the food we eat and biological information to improve prediction accuracy.

年次大会, 巻:2017, 号:0, 開始ページ:S1150204, 2017年Sign language is used for communicating with deaf persons. To facilitate the communication between the deaf and the hearing communities, a sign language translator is required. However, sign language varies from country to country. Furthermore, the number of words is increasing as society develops, and as a result, artificial translation has become challenging. Therefore, substantial research has been carried out to recognize and translate sign language by means of computing methods. In this paper, we propose a sign language recognition method that can adapt to video images captured by general-purpose cameras, and not by special input devices such as a depth sensor. According to this method, sign language regions are extracted from moving images by interframe difference image processing, and are recognized by using a convolution neural network (CNN). As a result of the one-person-leave-out cross validation experiment to recognize 30 words, the highest validation accuracy observed was 90.0%. Thus, the proposed method's potential for sign language recognition is manifested.

年次大会, 巻:2017, 号:0, 開始ページ:S1110401, 2017年In this paper, we aimed at obtaining knowledge about the effect of adding a virtual glass frame and additional information to the Virtual Reality(VR) image on VR sickness. The virtual glass frame is an object model imitating a glass frame arranged in the VR space. The frame is arranged to cover the peripheral visual field when viewing a VR image using a head mounted display. We created VR contents such a spin room and carried out comparison experiments between conditions where the virtual glass frame was added to the VR image using a questionnaire and bio-information. It was found that addition of the virtual glass frame to the VR image reduces the occurrence of vection in the peripheral vision and that the evaluation value of VR sickness decreases. Moreover, adding horizontal information to the frame reduces the confusion of vestibular sensation; furthermore, it was found that the evaluation value of VR sickness further decreases.

年次大会, 巻:2017, 号:0, 開始ページ:J1810202, 2017年Automation level 3 of an automobile is an automatic operation in the normal state;, however, the operation is switched to the driver when it is determined that operation of the system is difficult to continue. In previous study, there were cases where automatic operation cannot be smoothly switched from manual operation owing to motion other than driving, or a decrease in arousal level during automatic operation. It is considered that estimating the condition of the driver can support smooth switching. In this study, we estimated the state of the driver while automatic driving using seat surface pressure. Results indicate that the estimation was approximately 100% in the individual evaluation and 78.4% in the overall evaluation using machine learning. This suggests that it is possible to estimate the driver's state while automatic driving.

年次大会, 巻:2017, 号:0, 開始ページ:J1230103, 2017年Recently, some measures to prevent traffic accidents have been introduced; for example, information presentation by a head up display (HUD), vibration at the handle, and sound signals. However, the index to verify these utilities has not been established yet. According to a preceding study, the relationship between brain activity and negative emotion was observed by the near-infrared spectroscopy (NIRS). Moreover, other studies show that mental stress is related to galvanic skin reaction (GSR), respiration (RSP), and blood volume pulse (BVP). In this paper, we considered danger recognition to be associated with negative emotion and mental stress situation, and examined whether the status of danger recognition can be observed by combining bio-information. We observed that danger recognition is correlated to brain activity and GSR. Additionally, the oxy-Hb and GSR were observed to change when recognizing danger. This result suggests that measuring brain activity and GSR can be used to establish whether danger is recognized or not, and the potential of evaluating presence of danger recognition by using bio-information

年次大会, 巻:2017, 号:0, 開始ページ:J1230102, 2017年LEDs are widely used for backlighting of text indicators in vehicles. It is desirable that such text indicators have high legibility and low fatigue-inducing qualities. Suitable spectral distributions for text presentation in vehicles have not yet been clarified. This study examined legibility and fatigue when participants watched various text presentations. Participants read Japanese sentences that were presented by backlight emission, for 10 minutes in a dark room. The backlight indicators employed two color LEDs. The participants were asked to answer questionnaires to evaluate legibility and fatigue. Critical fusion frequency, brain activity and electrocardiogram were measured to evaluate fatigue objectively. Based on the questionnaire results, both colored backlight equal in legibility. Subjective evaluations showed that fatigue is more likely to be caused by high color rending white backlighting. On the other hand, objective evaluations (critical fusion frequency, brain activity and electrocardiogram) showed that fatigue is likely to be caused by high color rending white backlighting.

年次大会, 巻:2017, 号:0, 開始ページ:J1230106, 2017年It is said that music is effective for controlling feelings. For example, we can feel relaxed to listen to slow music. This paper proposes a generation system which composes music by means of a genetic algorithm. The composition which is generated by the system consists of the melody part, the chord part, and the bass part. The system can specify the atmosphere of the generated composition by choosing adjective words; "lightness", "intensity", and "complexity". To reflect the effect of adjective points on atmosphere of generated composition, the system adjusts the parameters of an evaluation function. As a result of a composition generating experiment, similar melodies and rhythms were found in each composition. To evaluate the appropriateness of the function about reflecting the effect of adjective points on atmosphere of generated composition, we conducted a questionnaire investigation. As a result, satisfactory answers are obtained for a specific adjective word.

年次大会, 巻:2017, 号:0, 開始ページ:J1230105, 2017年In recent years, the number of people who suffer from dementia has increased as the aging population increases. Since a standard method for the treatment of dementia has not been developed, there has been an attempt to combine the treatment of dementia with complementary and alternative medicine. Among complementary and alternative medicine methods, music therapy has attracted attention because of its low risk of side effects. Currently, group therapy is the mainstream of music therapy in Japan because of insufficient number of music therapists. As a result, care for individuals has not been sufficient. Therefore, it is necessary to provide pleasant music for each patient that can be automated. For this reason, a music selection system is required, and this system can be realized by measuring emotions using biological information such as brain activity. In this study, we analyzed brain activity while listening to classical music using near infrared spectroscopy. In our experiment, participants listened to four types of music with different characteristics. The results show that the oxy-Hb rises when participants feel uncomfortable, while the oxy-Hb decreases when participants dislike the music. This indicates that emotions and preferences while listening to music can be identified using brain activity.

年次大会, 巻:2017, 号:0, 開始ページ:J1230104, 2017年It is argued that, in human communication, the impression of a message is determined by nonverbal information. In this paper, we evaluated the relationship between human sensibility and eye movement. We conducted two kinds of experiments to induce a change in the psychological state. We used pictures of beverages as visual stimuli. A single image was applied in one experiment type, and double images were applied in the other experiment type. We carried out a questionnaire survey regarding the interest level with respect to the displayed image and measured eye movement with a gaze measurement system. The results indicated that the gaze time related to the displayed images with higher interest was longer in the double images experiment type. The number of blinks increased or decreased according to perplexity. The number of saccades increased or decreased in response to the perplexity levels in the double images experiment, and the change of saccades related to the interest in the single image experiment. These results showed that the eye movements have a potential for evaluating the psychological state.

IIP情報・知能・精密機器部門講演会講演論文集, 巻:2016, 号:0, 開始ページ:G, 終了ページ:1-3, 2016年A number of traffic accidents have occurred due to human errors such as inattentive driving and drowsy driving. Sleepiness is considered as one of the causes of these traffic accidents. For this reason, establishment of the sleepiness evaluation method during driving a car has been required. In this paper, we measured changes in cerebral blood flow during driving a car using a portable near-infrared spectroscopy device. The results show that oxygenated hemoglobin tends to decrease with the rise of the sleepiness level evaluated by facial expression and that there are negative correlations between oxygenated hemoglobin and sleepiness level in many trials. This suggests the possibility of sleepiness evaluation of a driver using near-infrared spectroscopy.

年次大会, 巻:2016, 号:0, 開始ページ:S1110203, 2016年In recent years, various driving support system has been developed as traffic accident prevention. However, they are unless transmitted to the intention that led to providing support, there is a possibility that the rather confusing the driver. Therefore, when the adoption of the driving assistance system, consider plenty the human visual attention to contribute significantly to cognition, without disturbing with the normal driving behavior, it is required a method for supporting recognition of the surrounding dangerous object. In this paper, we investigated the reaction time when subjected to experiments using dual task, has been presented a variety of auditory stimuli as lead cue stimuli. As a result, when using auditory stimulation with sound image movement, it tended to the reaction time of the central issue and the peripheral issues becomes earlier were observed. The result showed that the possibility of inducing an attention without considering the driver by using sound image movement as a visual assistance.

年次大会, 巻:2016, 号:0, 開始ページ:S1170402, 2016年In recent years, the number of dementia elderly person has been increasing. Various cognitive rehabilitation is underwent in nursing homes. However, it is difficult for them living far away from their home to undergo cognitive rehabilitation. Therefore, if they undergo cognitive rehabilitation in remote locations, many of them can improve dementia. In this research, we examined cognitive rehabilitation by cooperative between remote locations. When they undergo cognitive rehabilitation in remote locations, improvement of their presence is needed and it is assumed that cooperative operation can improve their presence. We chose a maze done by two persons cooperatively as concrete cooperative operation. In our experiment, firstly we compared brain activity between doing the maze and calculating because calculation is used as cognitive rehabilitation. Secondly we examined the possible of improvement of their presence during doing the maze. The result shows that the maze and calculation caused similar brain activity and cooperative operation improve presence. It reveals effectiveness of cognitive rehabilitation by cooperative between remote locations.

年次大会, 巻:2016, 号:0, 開始ページ:S1170305, 2016年Various walking assistance devices which promote rehabilitation and exercise for elderly have been developed. However, these devices can't support walking for exercise, because many elderly feels fatigue and bored in assisted walking. Therefore, the aim of our current study is to assist not only physically but also mentally elderly walkers to keep up their motivation. Concretely, we propose a walking promotion method that walkers listen to the beat sound adjusted according to their emotions with the ankle support assistance device. In order to confirm the effectiveness of the method, we conducted two experiments. The first experiment has four conditions where walkers have the device assist or not and the beat sound assist or not. As a result, the gait was improved with the device and sound assist where target cadences were adjusted according to their walking cycle. The second experiment has two conditions where walkers assisted sound adjusted according to their emotions or not. As a result, awakening levels perceived by the walkers remarked higher than ones in usual walking. These results showed the effectiveness of the method and possibility of the control of the emotion while walking.

年次大会, 巻:2016, 号:0, 開始ページ:S1170205, 2016年Many traffic accidents in car driving are associated with sleepiness. It is possible to prevent these traffic accidents by detecting sleepiness of the drivers while driving their car and making them pay attention to driving. Since the possibility that cerebral blood flow is related to sleepiness has been suggested, it is assumed that it would be able to evaluate sleepiness by the changes in cerebral blood flow. In this paper, we measured changes in cerebral blood flow during driving a car using a portable near-infrared spectroscopy device. The results show that oxygenated hemoglobin that is included in the cerebral blood flow tends to decrease with the rise of the sleepiness level evaluated by facial expression and that there is the significant difference in mean oxy-Hb between the two sleepiness level. From this vital reaction, it is suggested that the possibility of sleepiness evaluation of a driver using near-infrared spectroscopy and detection of driver's sleepiness at the level that driver's consciousness become low.

年次大会, 巻:2016, 号:0, 開始ページ:J1210104, 2016年In this research paper, we measured brain activities by near-infrared spectroscopy (NIRS) when a person is feeling the discomfort caused by vibration. In particular, we examined the effect on brain activation by the presence or absence of notice sound at the time of the start of vibration. We used a variance of oxygenated hemoglobin (oxy-Hb) as an evaluation index. We observed a difference in tendency of brain activation between the presence and absence of signal which affect participants in a surprising way. High negative correlation was observed between discomfort to vibration and brain activation around the medial prefrontal cortex, when value of surprise at the start of the vibration is small. High positive correlation is observed between discomfort to vibration and brain activation around the prefrontal cortex outer portion, when value of surprise at the start of the vibration is big. Possibility to evaluate the discomfort is suggested on the basis of brain activation which reflects the changes in the psychological state by surprise.

Here, we investigate and discuss the effect of accuracy of imitation for improvement of skills on brain activity. In order to improve the skills, learners combine and accumulate information of the skills through practice. Thus, we used near infrared spectroscopy (NIRS) to investigate brain activity during the process of improvement. Evaluation of the level of knowledge acquisition with monitoring of brain activity can be an indicator of the learner's degree of skill progression.Therefore, our final goal is constructing a new learning model based on brain activity monitoring and improving learning efficiency. We experimented on the assembly operation by imitation learning that assumed work in the manufacturing industries from a previous example. As a result, we showed the possibility of brain activity shift with improvement of the skill. In this article, we targeted task accuracy and investigated whether the brain activity shift is caused by a progress in the task accuracy, act of practice, or some other factor. As a result, we showed a possibility that the trend shift in the right and left dorsolateral prefrontal area and frontal pole was not caused by the simple task accuracy improvement but by the action of practice, which helped subjects store the information.

JOURNAL OF ADVANCED MECHANICAL DESIGN SYSTEMS AND MANUFACTURING, 巻:10, 号:4, 2016年
We developed a new method that can diagnose damage on a gear tooth surface using a laser beam without a rotary encoder. The method procedure is as follows: 1) The tooth bottom, the tooth tip and their two median values are detected using the differential values of the laser reflection data. 2) The gear rotation speed is calculated with these four positions, and interpolated according to the rotation fluctuation. 3) Using the calculated gear rotation speed, the measured data can be converted to the corresponding gear rotation angles. Thus we can diagnose the damage of the gear tooth surface precisely and can easily set up the experimental measurements without being influenced by rotational fluctuation. To confirm the validity of the method, we conducted the diagnosis experiment and we created contour maps to show the diagnosis accuracy variation according to the fluctuations of the amplitude and cycle. Based on these maps, we found that the diagnosis accuracy of the damage size is the same irrespective of the presence or absence of a rotary encoder. The diagnosis accuracy of the damage location without using a rotary encoder is lower than the result obtained using a rotary encoder because we assumed that the detection of the damage start point is delayed using this new method. Furthermore, we defined the limit using the conditions of this method from the sampling theorem; the validity of this definition could also be confirmed from the contour map.

We developed a walking assistance apparatus RE-Gait (R) for not only the elderly but also apoplexy patients, which assist the ankle joint of the equipped person. By only assisting the ankle joint, the equipped person's leg can be raised. To keep up the user's motivation for exercise using this apparatus, it is necessary to assist not only physically but also mentally. Therefore we suggested the new method of promotion walking, using the walking assistance apparatus while listening to the beat sound, which was adjusted according to a two-dimensional emotion map. In this paper, the relation between emotion map and walking condition map is shown.

PROCEEDINGS OF THE ASME INTERNATIONAL MECHANICAL ENGINEERING CONGRESS AND EXPOSITION, 2015, VOL. 11, 2016年
Emotional responses to color stimuli are referred to as color emotions, and relationships between color attributes and them have been discussed in past studies. In the current study, we reveal relationships between color rendering properties and color emotions to provide a light system controlling color emotions along with color rendering property. We developed such a system and conducted two evaluations of the system performance and color emotions under the light generated by the system. The system we developed in the current study has four color (red, green, blue, and yellow) LEDs to enrich color rendering property.In addition, we conducted a subjective assessment to explore relationships between color emotions and color rendering properties. In the assessment, we studied color emotions against facial skin irradiated by various illuminants with different color rendering properties. We prepared sixteen different light conditions and the participants of the study were asked to respond to the stimuli with fifteen Likert scales. As a result, we confirmed that the color rendering property certainly affects color emotions, and we obtained regression models to represent color emotions by color rendering properties. Furthermore, we found that male and female test subjects experience different color emotions based on skin color.

Many studies have been conducted during the last two decades examining learner reactions within e-learning environments. In an effort to assist learners in their scholastic activities, these studies have attempted to understand a learner's mental states by analyzing participants' facial images, eye movements, and other physiological indices and data. To add to this growing body of research, we have been developing the intelligent mentoring system (IMS), which performs automatic mentoring by using an intelligent tutoring system (ITS) to scaffold learning activities and an ontology to provide a specification of learner's models. To identify learner's mental states, the ontology operates on the basis of the theoretical and data-driven knowledge of emotions. In this study, we use statistical models to examine constructs of emotions evaluated in previous psychological studies and then produce a construct of academic boredom. In concrete terms, we develop ontological descriptions of academic boredom that are represented with statistical models. To evaluate the validity and utility of the descriptions, we conduct an experiment to obtain subjective responses regarding learners' academic emotions in their university course and describe them as instances on the basis of the ontological descriptions.

We developed a device that promotes walking which uses a two-dimensional emotion map for the exercise of the elderly. This map was made with two axes, the horizontal axis was pleasant or unpleasant, with the vertical axis being arousal or not, same as the circumplex model of affect (J.A. Russell (1980)). This device has two means to promote walking. One is an ankle joint assistance system, which consists of a servo motor and a controller which can adjust the targeted walking cycle, the targeted angle of the ankle joint, and the sensitivity of the sensors which was attached under the sole. The other is a beat listening system. The beat listening system makes the beat sound, which is decided for the purpose of the user, and based on the walking cycle. The user listens to the beat sound using head phones. By combining and using these two means simultaneously, users can change their gait and emotion, therefore, they can continue to walk for a long time.

This paper discusses human action modeling and its application to a control system that uses the Mahalanobis Taguchi System (MTS). In this study, we define embodied knowledge as being included in tacit knowledge. We also define a set of skills based on experiences and intuitive sense as seen in creating an art, sport, craft, or other skilled task. Embodied knowledge is difficult to express explicitly. As our goals, we analyze embodied knowledge acquisition for human action modeling and apply to a control system by using MTS.
An analysis of embodied knowledge using devices and pattern-recognition techniques to recognize un-explicit knowledge are being developed owing to recent improvements in technology. Embodied knowledge acquisition element of recognition can be represented as a pattern recognition technique. In this paper, we confirm that MTS is an adaptive method for recognizing pattern in human action modeling.
We set up a control model including a controller using the MTS, which is modeled after an internal model of the cerebellum. We apply the controller based on the Recognition Taguchi (RT) method to invert the control of the pendulum. The result indicate that the controller is capable of detecting disturbance.

Recently, view point of service has been widespread. In learning domains, service providers have been required to adopt it and to provide values co-created by teachers and learners. The value co-creation takes place in joint sphere where providers and customers make interaction, and the value is subjectively perceived by receivers (learners in learning service). That is, a mental state of leaner is one of possible value in the co-creation. The current study aims to develop a conceptual framework which describes mental states of learners for specifying values in the co-creation. As a result, we proposed ontological descriptions of learning event which consists of a teacher, a learner, learning materials, and a learning action by the learner. In concrete terms, we proposed ontological descriptions for receiver states in a learning activity, on the basis of a conceptual model of value co-creation. The ontological descriptions are useful for sharing knowledge on values perceived by learners to design learning services.

In recent years, the way to alleviate the disease by using of music that is so-called music therapy, has become popular in Japan. The music therapy is a therapeutic pedagogical technique which is carried out towards the recovery of cognitive and emotional disorders by using of music. Due to awareness of health in the super-aging society of Japan, demands for music therapy is increasing. However, it is difficult to appeal a preference of music for patients who have disorder of speech. Therefore, objective measurement method of emotion, like a measurement method of brain activity, is necessary for provision of music that fit each patients. In this paper, we conducted analysis of brain activity by using of Near-infrared spectoroscopy during listening to music. In our experiment, subjects listened to six kinds of music that combined various tempos and keys. The result shows that each combination of keys and tempos caused different brain activity. It reveals that emotions during listening to music can be identified by using of brain activity.

We developed a method which can diagnose damage on a gear tooth surface by using laser beam without a rotary encoder. This method is as follows: 1) The tooth bottom, the tooth tip and their two medians are detected by the differentials of the laser reflection data. 2) The gear rotation speed is calculated with these four positions, and interpolated according to the rotation fluctuation. 3) By using the calculated gear rotation speed, the measured data can be converted corresponding to the gear rotation angle. Thus we diagnose gear tooth surface damage without being influenced by rotational fluctuation. We did diagnosis experiments and we made contour maps show diagnosis accuracy. From these maps, we got the following conclusions: 1) The accuracy of damage diagnosis is the same level regardless of the presence or absence of a rotary encoder. 2) The cycle of rotational fluctuation hardly affects the accuracy. 3) Bigger fluctuation amplitude makes the range accuracy worse, however the position accuracy improves.

Proceedings of the ASME Design Engineering Technical Conference, 巻:1A, 2014年
Air-conditioning equipment is used in various places such as houses, office buildings, and public facilities and is indispensable in modern-day life. Therefore, the energy consumption of air-conditioning equipment accounts for a large percentage of the total energy consumption in the average household. Specifically, it accounts for 26% of the annual energy consumption in ordinary homes and 27% in industry, according to the Annual Energy Report for Japan, which was presented by the Ministry of the Economy, Trade, and Industry, and the Agency for Natural Resources and Energy in 2010. Therefore, it is desirable to reduce energy consumption by reducing the air-conditioning load. The Ministry of the Environment recommends a constant preset temperature of 28°C in summer to decrease energy consumption. However, many people feel uncomfortable in such a thermal environment. Thus, an air-conditioning control to simultaneously suppress energy consumption and maintain human thermal comfort is desired. To develop such a control, an index to accurately evaluate human thermal comfort is needed. When a person feels comfortable or uncomfortable, their prefrontal area, which is involved in thinking and the feeling of emotions, is activated. It is presumed that the measurement of the brain activation reaction of a person will reveal whether the person feels comfortable or uncomfortable in the thermal environment. The evaluation of thermal comfort by means of brain activation reactions will allow one to develop the optimum airconditioning control to maintain human thermal comfort. This paper proposes a method to evaluate thermal comfort via brain signals and ultimately aims to develop an air-conditioning control system utilizing this evaluation method. This paper will describe the measurement procedure of brain activation reactions to indoor-temperature change by using near-infrared spectroscopy and the relationship between thermal comfort and brain activation reaction. This study also investigated the changes in oxyHb levels together with indoor-temperature changes, measured with the NIRS. We measured the changes in the oxyHb levels of the prefrontal area when the temperature increased and decreased. As a result, the oxyHb level in the prefrontal area correlated with the indoor-temperature change, the PMV, and the subjects' declaration of thermal sensation. Conversely, the change in the oxyHb level with the inclusion of wind and a constant indoor temperature significantly differed with that with a varying indoor temperature. Furthermore, the oxyHb change correlated with the PMV and the subject's declaration of thermal sensation. Therefore, the measured oxyHb change may represent the thermal comfort of a person.

Research on brain-machine-interfaces (BMIs) is widespread and rapidly growing in concert with the rapid advances of recent years in brain science and engineering, and systems technologies for interactions between human and machine are of major interest. It is very important for development of BMIs to analysis brain activities. In this paper, we present measurement of brain activation response for weight shifting and center of gravity movement trials using near-infrared spectroscopy (NIRS). We measured their brain activations by NIRS. To evaluate effects of skin blood flow, we used probes with two distinct distances (15mm and 30mm) for NIRS and simultaneously measured skin blood flow. We also measured the position of the center of gravity using the ground reaction meter. The results showed that oxy-Hb changes were influenced by direction of movement. We also found that NIRS signals generally reflected skin blood flow. © 2011 The Japan Society of Mechanical Engineers.

Products fabricated by metal casting are affected by casting design and pouring. In order to design products efficiently, engineers must consider the shape of the pouring gate and the fluidity of metal in the runner. Engineers must envision the shape of the product and the fluidity of the metal in three dimensions. However, this task is difficult, especially for beginners. Therefore, we developed an augmented reality-based training system for metal casting that allows visualization of fluidity. The proposed training system uses simple physical operations to compute and display fluidity in real-time. Visualization of three-dimensional images as well as training on this system is simple. © KSME &

This paper describes a three-legged robot that consists of one actuated leg and two passive legs. The active leg has a knee joint and an ankle joint. The passive legs have no knee joint, although they have a passive ankle joint respectively. The passive leg part and the actuated leg part are linked by a hip part. The robot behavior is passive while the robot is supported by its passive legs and swings the actuated leg part. Generally, in the event that an actuator or a transmitting mechanism fails, robots cannot apply torques to the joint. We therefore took up a walking robot with passive knee joints not only for the energy-efficient walking but also with a view to making ambulation failsafe in case of mechanical failures.

When designing universal design products or their interfaces, it is necessary to have knowledge about the environment in which the target product is going to be used. Product development should consider the interaction between the envisaged product or a demo product with the same functions on the one hand, and the users on the other, as well as observing the everyday activities of typical users, understanding the procedures and methods for using the product and subsequently pinpointing the areas which are problematic or in need of improvement. To evaluate whether the designed product is easy to use, and to improve its usability, it is also essential to record the perceptions of the people, the movement characteristics, the operability, any mental or physical stress, and so on. There is a need for products and environments which are easily applicable to various people and utilizational setups. In this paper, we present the development of a tangible design review system which makes use of virtual reality technology to display a close model of the actual product, making readily available not only visual information but also the perception of volume and weight through the fusion of kinesthetic information, enabling many people to communicate easily while experiencing this virtual reality. Furthermore, the design review of universal design products which makes use of this system will be discussed.

This paper proposes a new virtual reality-based skill transfer and human resource development system for casting design, which is composed of the explicit and tacit knowledge transfer systems using synchronized multimedia and the knowledge internalization system using portable virtual environment. In our proposed system, the education content is displayed in the immersive virtual environment, whereby a trainee may experience work in the virtual site operation. Provided that the trainee has gained explicit and tacit knowledge of casting through the multimedia-based knowledge transfer system, the immersive virtual environment catalyzes the internalization of knowledge and also enables the trainee to gain tacit knowledge before undergoing on-the-job training at a real-time operation site.

Mechatronics systems are hybrid systems, which consist of mechanical system, electronic device, control system, computer software, and so on. For demands of higher precision and function enhancement, mechatronics systems have required parallel operation and cooperative control. This paper proposes a UML (Unified Modeling Language)/Petri net method for modeling and analysis of a mechatronics control system. Based on our UML/Petri nets representation, it is possible to generate the control program automatically. We have conducted simulations and confirmed that the proposed method UML/Petri nets is useful for control system analysis of mechatronics system.

Analytical results are presented for nonlinear vibrations of a timing belt with parametric excitation in tension and meshing impact forces. Galerkin method is employed to the equation of motion. The steady-state responses are calculated using the harmonic balance method. The numerical results yield the following conclusions. The resonant amplitude increases with the increase of pulley speed for constant tension. In the case of variable tension, the resonant peak value varies with rate of variable tension, and increases with increase of tension. Amplitude reduction by means of periodic variation of tension is effective for tension and rate of variable tension.

A number of traffic accidents have occurred due to human errors such as inattentive driving and drowsy driving. Sleepiness is considered as one of the causes of these traffic accidents. For this reason, establishment of the sleepiness evaluation method during driving a car has been required. In this paper, we measured changes in cerebral blood flow during driving a car using a portable near-infrared spectroscopy device. The results show that oxygenated hemoglobin tends to decrease with the rise of the sleepiness level evaluated by facial expression and that there are negative correlations between oxygenated hemoglobin and sleepiness level in many trials. This suggests the possibility of sleepiness evaluation of a driver using near-infrared spectroscopy.

Only attaching a laser sensor in a gear box, we can grasp the size and place of the damage on a gear tooth surface without using a rotary encoder. We confirmed the limit of this method against the velocity fluctuation. Furthermore, to utilize this system in the practical field, we developed a new system which was small, light weight, and low cost. The accuracy between new and conventional system was compared, and we confirmed the results were comparable level.

年次大会, 巻:2016, 号:0, 開始ページ:J1210102, 2016年In recent years, the research in intelligent educational systems has much interest in exploring data from educational settings to understand learners behavior and mental states. Therefore, the means to grasp psychological state of learner has been demanded from a more variety of physiological indicators. In present study, it aims to grasp how the learner approach to the question. By measuring the brain activated by using the multiple-choice questions, this study is to analyze the relationship between confidence and brain activation at the time of answer the question. As a result, in the prefrontal cortex frontal pole vicinity, tended to increase oxyHb when there is high confidence of the answer. In addition, answer time tended to be quick when there is high confidence of the answer. The result shows that it may be able to grasp the state of learner by measuring combination of the change of oxyHb and answer time.

設計工学・システム部門講演会講演論文集, 巻:2016, 号:0, 開始ページ:1101, 終了ページ:1101, 2016年Recently, value creation from view point of service has been widespread. A service process is regarded as a kind of interaction between service providers and receivers. Sharing and managing such the knowledge on human Kansei are of growing significance to providing product's values focused on customers. However, any sufficiently-advanced technologies that realize such knowledge sharing and management have been established. One typical approach is to clarify and systematize concepts as an ontology which is a basis to describe knowledge. In the current study, we discuss a method to develop an ontology describing knowledge on human Kansei and introduce several existing ontologies. The ontology will serve as a useful reference to develop value recognition map and be of assistance to designers.

We developed a walking assistance apparatus which can be used for neuro-rehabilitation of patients. This apparatus assists only the ankle joints of the equipped person and he/she can raise his/her leg by using the stretch reflex to bi-articular muscle. To confirm the effectiveness of the apparatus, we carried out the experiment for the patients of walking with wearing the apparatus, and the angle variation of the ankle was measured. From the results, by using this apparatus, the dorsiflexion and plantarflexion of the ankle joint of the equipped person can increase while walking. Furthermore, to grasp the lifetime limit of the apparatus, we developed the fatigue test apparatus for the power transmission device of the walking assistance apparatus: from the motor to the worm-helical gearbox through the flexible shaft. This apparatus supplies the power with the motor which is the same as the motor which is used in the walking apparatus. As a result, we could define the limit to replace of the flexible shaft according to the condition of the user.

The operational feelings of manual control levers are important to maneuver devices that need manual operations according to user's intentions. In this research, we built and tested a prototype of a manual control input lever of single degree of freedom using a magnetic particle brake in a rotational joint in place of the servo motors. And a one-way clutch is mounted on the rotating shaft so that the resisting torque of the magnetic particle brake is transferred to the lever in a one way. The drag torque was displayed haptically by appropriate actuation of the magnetic particle brake to support the manipulation. In order to assist in deciding the control input, the lever displays the resisting torque against user operations. The purpose of the presented system is to reduce the burden on the operation with respect to the intention of a user. We examine the influence of the resistance torque by psychophysical methods. The results of this research enable control input devices to adapt the ability of movement and preference of the user.

In this study, we developed the intuitive remote controlled manipulator system using touch panel display and mouse, and we examined the possibility of the application to the extraction work of the shoot apical meristem of the plant. The shoot apical meristem does not have the infection of the virus in the plant body. Therefore we can get a Virus-free seedling having high production efficiency by culturing this part. This technique is called "mericlone" and is known widely in the agriculture world, but this is hard labor because of precision work with microscope. This system we have developed not only reduce the burden on worker but also provide high precision controlling and space saving. In this study, with LAMP method (loop-mediated isothermal amplification method), we have confirmed that there was no PVX (Potato virus X) in the potato meristem with primordia using our developed manipulator system The newly designed primer set can discriminate the result.

Practical realization of service robots is in demand to compensate for the shrinking workforce due to aging populations. Robotics technologies can help support our aging populations in both social and work environments. We developed a manual control link mechanism using magnetic particle brakes at each joint in place of servo motors. This mechanism can be used to support a positioning action passively. It meets the requirements of safety, low acoustic noise, and high efficiency. In this paper, we describe the design and the dynamics analysis of a prototype mechanism, including the self-weight compensation, which is realized by appropriate driving of the magnetic particle brakes, and the resistance torque display to hold tilted position of the link.

There has been more interest in nursing-care robot in these days. Safety and reliability are required to these equipments. Additionally, low acoustic noise and energy saving performance are expected. In this research, we make a prototype of a link mechanism using magnetic particle brakes at each joint in place of servo motors. The magnetic particle brakes are proportional torque devices. The torque is controlled by varying the excitation current. This mechanism can hold up a target object and support positioning action passively. A dynamics analysis of the prototype is described at first and self weight compensation and force display to support positioning action is realized by appropriate actuation of magnetic particle brakes.

This paper proposes a new virtual reality mediated skill transfer and human resource development system for manufacturing technology and skill, which are composed of the explicit and tacit knowledge transfer systems using synchronized multimedia and the knowledge internalization system using portable virtual environment. In our proposed system, the education content is displayed in the immersive virtual environment, whereby a trainee may experience work in the virtual site operation. Provided that the trainee has gained explicit and tacit knowledge of casting through the multimedia-based knowledge transfer system, the immersive virtual environment catalyzes the internalization of knowledge and also enables the trainee to gain tacit knowledge before undergoing on-the-job training at a real-time operation site.

This paper proposes a concept of initial minimum safety spacing (IMSS) for a robot to avoid the collision with moving obstacles from any direction. A quick intelligent control system based on IMSS to avoid the collision is presented. In the system, the necessary deceleration and steering can be predicted using the fuzzy reasoning, which only needs to input one variable of the collision danger degree judged according to IMSS. So, the membership functions and the fuzzy rules are very simple, the calculation time for the avoidance is reduced. These advantages are verified by the numerical simulation results.

The environment where Japanese industry has been paid with respect is changing tremendously due to the globalization of economics, where Asian countries are undergoing economical and technical development as well as advancing in information technology. For example, in the design of custom-made casting product, a designer who is lack of casting knowledge may not be able to produce a good design. In order to obtain a good design and manufacturing, it is necessary to equip the designer and manufacturer with a support system related to casting design or so called, knowledge transfer and creation system.

巻:44, 号:1, 開始ページ:267, 終了ページ:274, 2001年03月
Based on motion and impact analysis, a theoretical model is presented for optimization of grinding performance of a tumbling ball mill. The motion of ball media in the tumbling ball mill is analyzed. The impact parameters of the ball media caused by the falling motion are deduced. The impact and attrition grindabilities are studied. The grinding performance is expressed as the proportion of grindability of all collisions to that of the collisions of ball media in the are of the shell at a theoretically suitable speed, and is calculated from the point of view of the separation layer. The mathematical model is established and program coding is implemented to optimize grinding performance for the tumbling bail mill. An example of design calculations is given which shows that the grinding performance under the optimized operation parameters is improved significantly.

Recently, industries cannot survive worldwide competition unless they introduce new products with better quality, at lower cost, and with shorter lead time in the production processes. But in the testing process it has not been automated, and the improvement is required. However, it is difficult to attempt the automation for manifold parts in the testing process, and to detect the color uneven area by the simple image processing. Therefore, the inspection is mainly carried out by the visual observation. The automation of the testing process is important thing in view of improvement of the inspection accuracy and shorter lead time. Then, this paper proposes new feature extraction and defects inspection method for slight defects and color uneven area of machine parts by using Wavelet transform. Using this method, the feature extraction filter and defects inspection system for color uneven area of machine parts are developed, and the color uneven area on the black rubber piece is detected. Our experiments have confirmed that the proposed methods are useful for color uneven area defects inspection for machine parts.

It is difficult to drive an actuator using muscular voltage measured by the conventional method, which is based on medical treatment and is not intended to elucidate the movement of an arm. In this paper, we propose a suitable measuring method to elucidate the movement by changing the position of an electrode. We also propose two evaluation values calculated from measured voltage to represent the movement of an arm. Using a fuzzy method based on these values, we can represent the movement of an arm fairly well. We applied this fuzzy method to driving an arm-type actuator, which can reproduce the movement of an arm.

Analytical results are presented for vibration of a wide timing belt under a moving load. The equation of motion is derived from Hamilton's principle, and approximate solutions to the basic equation are obtained using the Galerkin method. The steady-state responses are calculated using the harmonic balance method. Analytical results are presented which show the contributions of moving load position and moving load value to response curves. The response amplitude that varies with the width of timing belt. In the case of variable velocity, the response value shows very complicated behavior with pulley rotation. The response curves of vibration are greatly influenced by the moving load and the velocity.

We have developed a small jumping machine. For such machines, it is difficult to control the direction and velocity of motion by using conventional control devices, since there is not sufficient space to install them. Therefore we must develop another suitable control method. In this report, we investigate the following and movement control method of a small jumping target and elucidate its performance by analyzing graphical data extracted using a CCD camera. We propose a method of creating a virtual eye on the computer display, with which to follow a target. Moreover, we propose a controling method of jumping direction and velocity.

Analytical results are presented for nonlinear vibrations of a wide timing belt with parametric excitation in tension and meshing impact forces. The equation of motion is developed from Hamilton's principle, and approximate solutions to the basic equation are obtained using the Galerkin method. The steady-state responses are calculated using the harmonic balance method. Analytical results are presented which show the contributions of pulley speed and tension to natural frequencies. The resonant amplitude varies with cross section y. In the case of variable tension, the resonant peak value varies with the rates of variable tension, and tension. Amplitude reduction by means of periodic variation of tension is effective for tension and rate of variable tension.

Analytical results are presented for nonlinear vibrations of a timing belt with parametric excitation in tension and meshing impact forces, with application of the Galerkin method to the basic equation. The steady-state responses are calculated using the harmonic balance method. The numerical results yielcl the following conclusions. The resonant amplitude increases with the increase of pully speed for constant tension. In the case of variable tension, the resonant peak value varies with rate of variable tension, and inceases with increase of tension. Amplitude reduction by means of periodic variation of tension is effective for tension and rate of variable tension.

The tension in timing belts is subject to periodic fluctuation. This is brought about by factors such as an eccentric pulley and error of one pitch of the pulley, etc. This paper presents the regions of resonance of a timing belt. The equation of an axially moving timing belt with tension of periodic variation is developed. For theoretical analysis, the perturbation method of multiple scales is used. A study is carried on the instability regions with subharmonic and summonic types of parametric resonance. The effects of various system parameters, such as the timing belt speed and the gyroscopic matrix, upon the instability regions have been studied.

However, the existing control method for the positioning stage may cause delay of phase response or residual vibration when disturbance or overweight acts on the system or stage drives at high speed. In order to obtain the optimum control inputs, it is necessary to grasp the dynamic behaviour of the system precisely. First, this paper deals with the transient response of the positioning stage using the linear graph theory reported in the previous papers. The simulated results of transient response of the positioning stage are compared with the experimental ones, and they are found to be in good agreement. Next, a procedure which can reduce the settling time of positioning is proposed by utilizing this method. As a result, this procedure was able to reduce the settling time by 55%, as compared with only proportional control. 本文を読む・探す CiNii PDF他のリンク1図書館所蔵NII論文ID (NAID)110002380194NII書誌ID (NCID)AN00187463本文言語コードJPN資料種別論文NDL雑誌記事ID0162651700NDL記事分類機械の要素・機構学NDL雑誌分類ZN11(科学技術--機械工学・工業)NDL請求記号Z16-1056収録DBNDL NII-ELS書き出しRefer/BibIX形式BibTex形式タブ区切りテキスト (TSV)

身体的引き込みと対話場の生成メカニズムの解明、およびその対話場生成・制御メカニズムのモデル化を達成するために、【研究1】これまでに開発してきた(Ⅰ)身体的コミュニケーションの合成的解析・理解のための身体的バーチャルコミュニケーションシステム、(Ⅱ)コミュニケーション支援のための音声に基づく身体的インタラクションシステム、(Ⅲ)コミュニケーション場の生成制御のための集団インタラクション・コミュニケーションシステムを研究開発展開し、対話場の生成・制御システムのプロトタイプを構築している。リズム同調を損なうことなく言語的なインタラクションを行うシステムとして、発話内単語の感情極性に基づき反応動作を行う身体引き込みキャラクタシステムや発話単語から生成されたオブジェクトが引き込み反応することで発話を促進するシステム等、各種の身体的引き込みシステムを開発展開し、官能評価及び対話者のインタラクション行動特性解析によりシステムの有効性を示した。また、【研究2】生体計測と脳科学に関する知見に基づく発話と心的状態の関連性の評価から、脳機能計測(NIRS)を用いて対面・画面越しの会話におけるうなずきの有無による身体的引き込み現象の脳賦活解析により、前頭前野における会話時の引き込み現象を分析評価し、条件によって引き込み現象が起こる脳部位が変わることを示した。さらにGiannopulu教授(オーストラリア・ボンド大学)との国際共同研究で、身体的引き込み技術を応用した身体的インタラクション玩具を用いて各国での自閉症児と健常児を対象に生体情報計測および発話行動分析・官能評価し、システムのコミュニケーション効果を実証した。

まず一つ目は、1人の美術専門家にあらかじめ設定した項目に従って児童画を評価してもらいそれを用い機械学習のための教師データの作成を行い、教師データを使用して機械学習モデルを作成した。そのモデル検証のため学習に用いていない児童画を用いた予測値と専門家が評価した値を比較し平均絶対誤差を算出した結果,5段階の評価値において平均絶対誤差は0.606となり、専門家の評価をある程度学習できてはいるが更なる精度の向上手法について調査を今後進めていく。二つ目は、モニターに提示された小学生の児童画の鑑賞絵を絵の専門家,小学校教員,児童絵に行ってもらい,その間の反応を視線計測によって記録した。そのデータを解析し視線が収束する箇所のフラクタル次元数に差異があるかを評価した。その結果学生と絵の専門家の間には絵の見方に違いがあり、小学生は最初に複雑な高フラクタル次元の絵内の事物に先に視線をあて,専門家は美しいとされている中位のフラクタル次元の絵内の事物に最初に視線を集める事がわかった。三つ目の実験として、モニターに提示された児童画の鑑賞と評価を参加者に行ってもらい、その間の反応を、アイトラッカーによって記録した。図工の作品としての評価、美術作品としての評価、好き嫌いの評価の3種類の教示の違いによって、絵画の視覚的特徴に基づくボトムアップな処理と評価の目的に基づくトップダウン処理がどう相互作用するのか調査した。また各参加者に印象評価に関するインタビューも実施した。調査の対象は一般大学生である。教示の違いから生じる差をもとに、実際の教育場面で教師が絵を見取ろうとした際にどう評価するかに関する検討を試みた結果、絵を見る際の視線の動きや各絵に対する評価の得点は教示によって異なることが示唆され、インタビューの結果から、教示の違いによって評価時に意識する内容や評価のしやすさに違いがある可能性が示された。
