We aimed to develop a tactile display that allows users to actively explore the virtual texture of a surface. We developed a tactile display embedded in an optical mouse that provides a wide range of frequency vibrations to the user's fingertip in response to its movement. We conducted an experiment to confirm the degree of fineness based on a stripe pattern identification task using a trial system. The results showed that the subject could identify a fine spatial resolution up to 0.16 mm width.
