Title:


    HORN: The Hapt-Optic Reconstruction

Description:


    In this paper we propose a system that superposes a haptic sensation on a mid-air floating image based on ultrasonic standing waves. Conventional approaches of using airborne traveling ultrasounds could only apply weak pressure to the finger surface from a certain angle and thus a limited haptic sensation. Also, the ultrasounds generated air flow as a side-effect [Hoshi et al. 2009].

    Here, the use of focused standing waves generated by the system shown in Figure 1 enables creating spatially varying acoustic pressures in all directions. In addition, this method suppresses the air flow. Such standing waves are employed to realize an elastic haptic feedback and to offer a rich haptic experience. Combined with ultrasonic beam steering and floating images, this system can display a virtual spherical gadget that is “pinchable” and “movable.” Thus, an intuitive human-computer interaction can be offered.
