In recent years, tactile display technology in virtual reality and teleoperation is widely studied. However, it is still difficult to display complicated texture of objects in detail. It is particularly difficult to display tactile sensation without relative motion between finger and tactile display. Accordingly, we propose a novel tactile display, which has an ultrasonic vibrator and a movable strip of paper located between finger and the vibrator. The strip of paper provides a relative motion between finger and vibrator, that is, an active touch which is important for human to perceive roughness of an object. Using the tactile display we developed, we clarify the characteristic of tactile perception during active touch.
