2P1-P01 Pseudo-Haptic Feedback Augmented with Vibrotactile Stimulation Simulating the Geometric Relief(Tactile and Force Sensing(2))

Abstract

Pseudo-haptic feedback is one of the most practical methods for presenting haptic cues without haptic device, in which visual stimuli accompanied with the user's motion generate illusory haptic sensation. The temporal response of the sensation is relatively slow, typically expressed as mass or viscosity. On the other hand, high frequency component of tactile sensation, i.e. vibrotactile feedback is also an important factor of haptic perception, which is quite difficult to present using pseudo-haptic feedback. In this paper, we propose to integrate vibrotactile feedback with pseudo-haptic feedback, so that it could strengthen the perception of pseudo-haptic effects. We demonstrated that the perception of the geometric relief was improved by the integration.
