Haptocolne is a new interactive system that can display haptic and optical clone image in mid-air.
This system has two workspaces apart from each other but the two workspace fields are virtually “superimposed” optically and haptically. Each lightfields and forcefields of both ports is cloned and forwarded to other ports.

A thermography camera was found to provide real-time and high spatial resolution measurements. The study revealed two key findings: the visualization of a two-dimensional ultrasonic field using a mesh screen, and the measurement of sound pressure distribution on the surface of hands and fingers.

Abstract: Ultrasound emitted from an array of transducers can produce various tactile sensations by temporally controlling the phase and amplitude of the transducers. However, the controllability in haptic applications has not been well examined. This article clarifies a phase shift of the driving signal causes amplitude fluctuation of emitted ultrasound, even under a constant driving amplitude. We demonstrate theoretically that this problem exists in general resonant systems with various quality factors, and point out that it produces radiation force decrease and audible noise. We also show a method to reduce the fluctuation and quantitatively evaluate the effectiveness. The results provide the measure of the displayed force fluctuation by a fast focus movement and enable silent haptic stimulation.

ABSTRACT: Physically moving real objects via a computational force connects computers and the real world and has been applied to tangible interfaces and mid-air display. Many researchers have controlled only a stationary real object by computational force. On the other hand, controlling a moving object can expand the real space that is controllable by the computer. In this paper, we explore the potential of computational force from the viewpoint of changing the trajectory of a moving object. Changing the trajectory is the primitive model to control a moving object, and it is the technological challenge requiring high-speed measurement and non-contact force with high-spatial resolution. As a proof-of concept, we introduce Hopping-Pong changing the trajectory of a flying Ping-Pong Ball (PPB) using ultrasound force. The result shows that Hopping-Pong changes the trajectory of a PPB 344 mm. We conclude that a computational force is capable of controlling a moving object in the real world. This research contributes to expanding the computationally controlled space with applications for augmented sports, HCI and factory automation.Three-dimensional Interaction Technique Using an Acoustically Manipulated BalloonShinodaLab2019-11-25 | ...Midair Hand Guidance by an Ultrasound Virtual HandrailShinodaLab2019-10-17 | ieeexplore.ieee.org/document/8816123Prediction of Volleyball Trajectory Using Skeletal Motions of Setter PlayerShinodaLab2019-03-18 | dl.acm.org/citation.cfm?id=3311844Ultrasonic Rigid Body LevitationShinodaLab2019-01-24 | Levitation of macroscopic non-spherical rigid bodies larger than the sound wavelength.

X(Cross)-SectionScope is a novel interactive 3D information display that superimposes a cross sectional image in an aerial image of a physical object. Multiple mirrors reproduce a 3D image of the object in the air. You can scope the cross sectional image of the object by inserting a semi-transparent screen into the cloned image.Ultrasonic 3D Haptic Hologram, demo at whc15ShinodaLab2015-07-18 | This demo shows volumetric haptic objects in the air using spatial modulation of ultrasound. The proposed approach produces a spatially standing haptic image using stationary ultrasonic waves that enable users to actively touch 3-dimensional images without depending on vibrotactile stimulation and sensor feedback, which is a completely silent and free of the problems caused by feedback delay and errors.
Note that the attached infrared detector (leapmotion) is not used for ultrasonic control.HaptoMime (full version): Mid-air haptic interaction with a floating virtual screenShinodaLab2014-10-06 | Best Demo Award at ACM UIST'14!
We present HaptoMime, a mid-air interaction system that allows users to touch a floating virtual screen with hands-free tactile feedback. Floating images formed by tailored light beams are inherently lacking in tactile feedback. Here we propose a method to superpose hands-free tactile feedback on such a floating image using ultrasound. By tracking a fingertip with an electronically steerable ultrasonic beam, the fingertip encounters a mechanical force consistent with the floating image. We demonstrate and characterize the proposed transmission scheme and discuss promising applications with an emphasis that it helps us 'pantomime' in mid-air.

Airborne Ultrasound Haptic Field & Aerial 3D Imaging
The use of focused standing waves generated by HORN's surrounding phased-array system enables creation of spatially varying acoustic pressures in all directions. Such spatial variation of acoustic pressure produces a haptic feeling of an elastic surface and offers a rich haptic experience. Combined with ultrasonic beam steering and mid-air floating images generated by numerous micro-corner reflectors (AIP developed by ASUKANET), this system can display a virtual gadget that is “pinchable” and “movable". It offers intuitive human-computer interaction.Visuo-Tactile ProjectorShinodaLab2013-05-14 | Visuo-Tactile Projector is a device which simultaneously projects visual images and tactile stimuli on the surface of human skin.
