This paper presents a displaying method of button like click feeling using ultrasonic vibration with amplitude of a few micrometers. Artificial click feeling is displayed by recreating rapid change in force arising from buckling of a mechanical push button utilizing squeeze film effect. First, important factors for displaying click feeling were extracted by analyzing the relationship among force-stroke...
A small tactile display that can be attached to a mobile terminal device or a handheld game controller will enhance user experience in virtual worlds. This paper proposes an ultrasonic vibrator which has a compact mechanism to produce vibratory stimulation on human skin using a pin array driven by a single piezoelectric actuator. Amplitude modulations of the ultrasonic vibration can generate tactile...
In the present study, tactile display of surface texture by use of amplitude modulation of ultrasonic vibration is developed. First, systems are constructed to display artificial tactile sensation using ultrasonic vibrator. Then, sensory evaluation experiments are conducted to confirm that output stimulations in response to hand velocity is effective to realize an artificial tactile sensation. Next,...
