手背への振動触覚刺激を用いた情報提示

抄録

With the advancement of information technology, haptic devices are receiving attention over the last few years. However, transmission of detailed information, such as character information, by using haptic devices has not been achieved. Therefore, in order to establish a technique to transfer character informatoin by a tactile feedback, we have developed a haptic feedback system that is capable of presenting vibro-tactile stimulation on dorsum of hand. We examined three key parameters of the vibro-tactile stimulation: position, direction, and time difference, by psychophysics experiments and revealed their effects on the accuracy of information recognition. Finally, we derived an optimum condition between vibrator and skin in a dorsum of hand.
