Abstract
A system is proposed which enables users not only to operate computers by moving their hands in mid-air but also to feel touch feedback on their hands. The system consists of a PC, a markerless hand-tracker for input, and a non-contact tactile display for feedback. The tactile display utilizes ultrasound to produce tactile stimulation from a distance. It is based on a nonlinear phenomenon of ultrasound (acoustic radiation pressure) and the phased array focusing technique. The principles are described and the prototype system is introduced.
