  We propose a focusing method of intense midair ultrasound out of ultrasonic emission from a single flexurally vibrating plate partially covered with a purposely designed amplitude mask. Many applications relying on nonlinear acoustic effects, such as radiation force employed in acoustic levitation, have been devised. For those applications, focused intense airborne ultrasound is conventionally formed using phased arrays of transducers or sound sources with specific fabricated shapes. However, the former strategies are costly, and the latter may require minute three-dimensional fabrication processes, which both hinder their utilization, especially in constructing a large ultrasound-emitting aperture. Our method offers a possible solution for this, where the amplitude masks are designed depending on the positions of nodes and antinodes of the vibrating plate. We experimentally demonstrate the successful formation of midair ultrasound focus at a desired position, which is localized in a region whose diameter is less than a few wavelengths. Our method only requires a monolithic plate, a driving transducer under the plate, and an amplitude mask fabricated out of laser machining of an acrylic plate. Magnification of the spatial scale of ultrasound apertures based on our method is much more readily and affordably achieved than conventional methods, leading to new midair ultrasound applications with the whole-room workspace.

  In this paper, we propose an image and tactile presentation system for quickly moving objects, high-speed dynamic information environment, and a calibration method between a camera and Airborne Ultrasound Tactile Display(AUTD), which can present tactile sensation noncontactly as focused ultrasound. We realize one example of high-speed dynamic information environment that even if an object is moving, we can use the object as a tool for human interfaces without delay by combining a high-speed gaze controller by rotational mirrors. An accuracy of position, however, is not sufficient against difference threshold between images and tactile sensation because of mainly error of position between AUTD and camera. We calibrate the AUTD-camera system by visualizing the invisible focal position using Frustrated Total Internal Reflection(FTIR). Experimental results show that estimation accuracy is better than the threshold.

• Manual Character Transmission by Presenting Trajectories of 7mm-high Letters in One Second　　　　　　　　　　　　　　　
  Keisuke Hasegawa; Tatsuma Sakurai; Yasutoshi Makino; Hiroyuki Shinoda
  24 Mar. 2015
  In this paper, we report a method of intuitively transmitting symbolic
  information to untrained users via only their hands without using any visual or
  auditory cues. Our simple concept is presenting three-dimensional letter
  trajectories to the user's hand via a stylus which is mechanically manipulated.
  By this simple method, in our experiments, participants were able to read 14
  mm-high lower-case letters displayed at a rate of one letter per second with an
  accuracy rate of 71.9% in their first trials, which was improved to 91.3% after
  a five-minute training period. These results showed small individual
  differences among participants (standard deviation of 12.7% in the first trials
  and 6.7% after training). We also found that this accuracy was still retained
  to a high level (85.1% with SD of 8.2%) even when the letters were reduced to a
  height of 7 mm. Thus, we revealed that sighted adults potentially possess the
  ability to read small letters accurately at normal writing speed using their
  hands.

  <p>We propose a method that enables a data glove to estimate the positions of the wearer's fingers out of the two different measurements, a vision-based marker tracking and an orientation estimation with 9-axis sensors. Since these measurements have inherently different temporal scales, we integrate them using the complementary filtering techniques. In derivation of the proposed estimation algorithm, we introduce a simplified model of finger movements in order to associate the output of 9-axis sensor with the finger positions. We experimentally evaluated the validity of the proposed method. Our method requires only several tiny sensors and electronic components equipped on the glove, which allows the glove to avoid being bulky.</p>

  <p>This paper proposes a pocket-size device that enables users with no prior long-time trainings to intuitively read text letters using only their haptic sense. The device forces the user's finger-tip to trace trajectories of alphabet characters. Vibrotactile stimuli are superposed on fingers so that users can distinguish writing strokes from transient movements of fingers between strokes. The device structure, displayed motions, and experimental results of character reading are shown. The results suggest that the access to symbolic information via haptic modalities would turn into practical applications for people with late blindness or even people with normal vision.</p>

  <p>In this study, we examine a method for guiding the users' hands to a specific region in the air, by utilizing Airborne Ultrasound Tactile Display (AUTD). The AUTD is a device that creates focused airborne ultrasound on the surface of human skin resulting in perceivable vibrotactile stimuli. Measuring the position of a hand in real time, the fabricated system allows users to tactually feel a virtual wall out of focused ultrasound that is accordingly generated. The AUTD is placed on the left side of the workspace yielding rightward radiation force onto the palm of the user. In this paper we particularly discuss the human performance of locating horizontal position displayed by the system, in terms of its accuracy.</p>

  In this paper we propose a method for calculating ultrasound phase and amplitude of transducers in an array which accomplishes the desirable spatial distribution of resulting ultrasound amplitude for generating tactile sensation on human bodies in a remote and non-contact way. Based on the principle of acoustic radiation pressure, a region where the sound pressure is high enough, pushes the surfaces of objects located in it. A three-dimensional ultrasound amplitude distribution can be designed with our calculation method and thus three-dimensionally expanding remote tactile stimuli can be generated. We operated a few numerical simulations to verify the validity of our proposal method.

  The main results of this research are summarized into the three following topics. (1) A construction method of acoustic intensity field that corresponds to acoustic streaming field to generate is established by means of continuous optimization of amplitude distribution with a proper regularization. (2) An arc-shaped intense ultrasound beam is generated by creating series of congregative ultrasound foci that forms the beam. It is verified that the acceleration of air is done in direction of the beam tangent at each line segment of the beam. (3) Binary M-sequence pattern of ultrasound amplitude is generated in the workspace to enable a single monoaural microphone to estimate its self-position. In this framework, the amplitude pattern is spatially scanned so that the microphone position can be retrieved using amplitude signal received by the microphone as a position-dependent positional clue.

  We succeeded in generating a narrow, straight and steerable airflow that is accompanied with ultrasound Bessel beam emitted from a phased array of ultrasound transducers. The cross-sectional area of the flow was observed to be almost comparable to several times of the ultrasound wavelength. Based on this technique, we achieved remote fragrance presentation to a specific user in a personalized fashion, where the scent was transported from the scent source to the user’s nostril via the ultrasound-driven airflows. We also demonstrated that selective transportation of a specific kind of scent out of several sources located close to one another was also possible by our technique. We created a system that offered face-tracking scent that targeted freely moving users wearing no devices.

  This study aimed at conveying symbolic information to human via only haptic modalities based on the “write to read” approach where the users’ hand and fingers were guided along the letter trajectories by external force applied by the mechanical device that we fabricated. As a result, users were able to identify the lower-case alphabets presented by a fabricated desktop system at an accuracy rate of more than 90% without any prior long-time trainings. We also implemented its hand-held version supposed to be used in practical situations, which successfully conveyed the letter trajectories to untrained users. We demonstrated that this method is superior to the conventional ones in the context of intuitiveness.

  Super haptics is haptic human support free from the problems and constraints ascribed to the mechanical contact between the human and haptic stimulators. First in this study, the elementary technology to stimulate a human skin using airborne ultrasound was established. We also developed a sensing technology for remotely measuring the generated force of a human hand. Based on those technologies, we realized novel interface systems: Aerial touch panel in which we can operate floating images with haptic feedback, Haptic-optical clone system that realizes symmetric mutual telexistence in which we can remotely touch each other through realistic 3D images, and a motion navigation system where a hand is navigated by noncontact ultrasound stimulation.
