This paper describes the capability of a pin-typed tactile display to present virtual textures. Each pin of the tactile display was driven by a bimorph PZT ceramic actuator; the stroke of the pin was about 1mm. The size of the pin-array was 8-by-8; the pin-array typed tactile display was mounted on a mouse. In order to evaluate virtual textures presenting of the display, virtual textures are expressed by an equation of convolution of two-dimensional sinusoidal waves and human subjects adjust one of parameters included in the equation in the psychophysical experiment. In a preparatory experiment, two human subjects adjusted a y-/x-directional wave number ratio. r. Since Δr/r was within from 0.2 to 0.35 where Δr was difference between adjusted and provided wave number rations, and the value of Δr/r was almost same as normal Waber fraction for tactile sensation, the present mouse could display the virtual texture.
