title = "Study on tactile perception of shape for effective tactile display",
abstract = "The experiment of the shape recognition for a tactile display is carried out and analysed in this paper. The purpose of this research is the development of a tactile stimulator array to represent the obstacle information for the visually impaired to walk safely. 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 and optimal range of the actuating frequency and displacement for the tactile stimulation array, the psychophysical experiment for the threshold of perception and recognition ability of multi-stimulation with some shapes are 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.",
