Abstract
This study proposes a noncontact method to provide thermal sensation. It was observed that the plate is heated when slits on a plate are exposed by a high-amplitude ultrasound. There is a possibility to provide thermal sensation remotely by utilizing this phenomenon. Users' motion is not restricted by wires etc. Furthermore, arbitrary positions can be heated because our ultrasonic device has an ability to move a focal point of high-amplitude ultrasound. This paper gives an explanation of this phenomenon and experimental results.
