Vibrotactile Apparent Movement by DC Motors and Voice-coil Tactors

Vibrotactile displays are expected to be effective tools for presenting personal information. We investigate the possibility of showing various kinds of information by making use of tactile apparent movement. As a first step, we observe the occurrence of apparent movement for various values of stimulus duration and stimulus onset asynchrony for two types of tactors: DC motor-based vibrating motors and voice-coil type tactors. The results show the effectiveness of using voice-coil type tactors for presenting information in a short time. Key words: Vibrotactile, apparent movement, vibrator 1
