表面の凹凸と振動，摩擦力に基づく触感提示装置

A tactile display that can control mechanical stimulation to the fingertip is useful for researches on perception mechanisms. In this study, for the analysis of texture sensations, we developed a tactile display that can simulate the vibration and the frictional force derived on the skin when a human slides an object with a fingertip. Besides, the contact surface can be exchanged. It is composed of a vibrator, a voice coil motor, a load cell, a flat plate with different surface geometries, and a monitor. The finger is fixed and a feeling of the movement of the fingertip is compensated with the monitor. Basic evaluation tests showed the reproduction of the vibration and frictional force, inducing different roughness perceptions.
