  • 2A2-O06 All-around Tactile Stimulation by Using Multiple Arrays of Ultrasound Transducers(Tactile and Force Sensing (1))

抄録

A noncontact tactile display is developed in our laboratory, which provides tactile stimulation in midair by utilizing a nonlinear phenomenon of ultrasound; Acoustic radiation pressure. In the previous reports, a single or two arrays of ultrasound transducers are used and the resulting force acts only in one direction. That would limit the application area of the tactile display. In this paper, four arrays are arranged so that a user's hand is surrounded by them. The user can feel sufficient tactile stimulation in any direction owing to this array configuration.
