Simultaneous Presentation of Thermal and Mechanical Stimulation Using High-Intensity Airborne Ultrasound

In this study, we propose a non-contact thermal presentation method using airborne ultrasound. We generate strong sound field directly on the human skin and present a perceivable temperature rise. The proposed method enables simultaneous presentation of mechanical and thermal stimuli. In preliminary experiments, we confirmed that temperature increase of 5.4 ${}^\circ$C occurs at the palm after 5.0 s.
