This paper describes the capability of a pin-typed tactile display to present virtual striped textures. Each pin of the tactile display was driven by a bimorph PZT ceramic actuator; the stroke of the pin was about 1 mm. The size of the pin-array was 8-by-8; the pin-array typed tactile display was mounted on a mouse. Two display pads were produced; one's pitch of tactile pins was 1 mm; the other's was 1.8 mm. In order to evaluate presentation capabilities of the tactile display, the authors conducted a series of psychophysical experiments. In the experiments seven human subjects adjusted a crossing angle of a comparison texture to be equivalent to a standard texture. From the experimental results, it was found that the pitch of 1.8 mm was enough to present the striped textures, and that the pin stroke being larger than 250 μm at least was need to present them.
