Proposal of Tele-touch Using Active Type SAW Tactile Display

DOI

Description

We have already proposed a novel method to provide human tactile sensation using surface acoustic wave (SAW). In this paper, we propose "tele-touch", which realize reproduction of tactile sensation as if to rub remote solid surface. To generate tactile display control parameters, object surface is measured by a fabricated profile scanner. Control parameters are generated from the result. To indicate various texture, we install amplitude modulation for SAW excitation. Demonstration to reproduce the tactile feeling of sample surface with the control parameters and the modulation drive is carried out.
