Variation of Tactile Feelings of Focused Ultrasound: Modulation Frequency and Hand Movement


Ultrasound-based aerial haptic feedback has been studied these days. Studies on this technology mostly focused on producing contact sensation in air and investigating the characteristics of human tactile sensation. There are a few reports on the quality or metaphor of the produced tactile feelings. For example, 100-Hz or 200-Hz modulated ultrasonic stimulation was expressed as “electrostimulation,” “a stream of air,” and “a small soft-haired blush” in the previous report. Synthesizing realistic tactile feelings, such as recorded from real blanket, is still remaining a difficult technological issue because of controlling hundreds of ultrasonic transducers. In this paper, two interesting phenomena are reported which were found through demonstrations/exhibitions with the current ultrasonic device. One is frequency-dependent size sensation, and the other is movement excited virtual sphere. In this workshop, you can touch and feel these sensations.
