Abstract
The purpose of this research is the development of a tactile stimulator array to represent the obstacle information for the visually impaired. As a first step of this research, we investigate the characteristics of tactile stimuli and design the experimental system for the physiological characteristic test based on the investigated results. In order to determine the appropriate/optimal range of the actuating frequency and displacement for the tactile stimulation array, the psychophysical experiment for the perception threshold and recognition ability of multi-stimulation with some shapes were carried out by the estimation of the subject group. As a result the appropriate tactile stimulus intensity and frequency of the tactile stimulation array to recognize arbitrary line shapes effectively are discussed and derived.
