A novel interface to present emotional tactile sensation to a palm using air pressure

Abstract

We propose a new tactile interface to present various types of tactile sensation, especially a feeling of "softness". A user holds our interface, containing two speakers, with both hands while the speakers vibrate air between the speakers and palms. The user feels suctioning and pushing sensations to the palms due to the air pressure. By changing the frequency of vibration, the user experiences not only normal vibration but also "soft" feelings like that of liquid, spring-like objects, and living matter.
