When we rub physical surface with pen or stylus, we can feel tactile sensation through it. The reproducing of such realistic tactile sensation is focused recently and some devices have been developed. On the other hand, many devices proposed only low frequency sensation, that frequency is considered as peak frequency of mechanoreceptor sensitivity. In this research, adding high frequency vibration to tactile sensation indication was proposed. To confirm high frequency vibration on surface acoustic wave (SAW) tactile display, its frequency response was measured. We conducted a psychological test to investigate the perceptual threshold that human can feel on SAW tactile display. We confirmed that human feel the high frequency vibration.
