Noncontact Haptic Interface Using Ultrasound

Part of the Lecture Notes in Computer Science book series (LNCS, volume 6851)


The current haptic technologies in 1-to-1 teleoperations, mobile communications, and computer games have already moved into a phase of practical use. One of the next attractive challenges is haptic assistance to unspecified people in public spaces. The potential demands for haptic assistance include alarming and guiding people, delivering knowledge and experiences, collecting people’s intentions, and offering entertainment in public spaces. We need a technological leap from the conventional mechanical methods to enable ordinary people to enjoy public haptic assistance without special devices held in their hands. In this keynote speech, a non-contact tactile display using airborne ultrasound is introduced as a solution. Radiant pressure by convergent ultrasound beams produces tactile sensations on bare skin. It is even possible to apply haptic stimulations to people moving around in an open space. Combining the tactile display with 3D images realizes programmable 3D interfaces with tactile responses. The basic principle, characteristics, and limitations are explained. Also, the future of noncontact haptics, including remote haptic sensing and haptic sharing, will be discussed.
