Abstract

This paper investigates the factor influencing the design of vibrotactile sensory substitution system for prosthetic hand. The coin motor is used as the vibrotactile stimulator because of its smaller size and cheaper price. This study is to develop a vibrotactile system to study the possibility for finger localization feedback. Three types of stimulator configurations and three level of vibratory frequency were tested in this study, which are vertical, rounded and u-shape configurations. Seven subjects were participating in the experiment and total of 255 stimuli were given to each subject. The results demonstrate that U-shape configuration and higher vibratory frequency is the best vibrotactile placement for finger localization feedback.
