抄録

This paper proposes contactless touch screen with tactile sensation. Users can interact with the screen without actual touch and feel tactile feedback. The device is composed of a screen, visual projectors, sensors for finger motion detection and airborne ultrasound phased array, which displays tactile sensation. The important component of the system is a screen that scatters projected image and transmits ultrasound. The screen has another potential for cutting off air flow, which makes tactile images unclear. We show the design of the screen and examine the effectiveness through simulations and experiments. After that, we construct the contactless touch screen systems and examine position recognition test under the support of tactile sensation.
