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...
Simple grippers with one or two degrees of freedom are commercially available prosthetic hands; these pinch type devices cannot grasp small cylinders and spheres because of their small degree of freedom. This paper presents the design and prototyping of underactuated five-finger prosthetic hand for grasping various objects in daily life. Underactuated mechanism enables the prosthetic hand to move...
This paper presents a hybrid tactile displaying method of realistic texture using ultrasonic vibrator and force display. The aim of this study is to display various realistic tactile senses by controlling multiple factors including roughness, softness and friction sense. First, a tactile displaying system was configured for displaying roughness, softness and friction sense simultaneously by compensating...
