The Tactile Display which Presents Shear Deformation on Human Finger.

This paper proposes a tactile display for presenting shear deformation to the skin of the human finger. Human can get much information from the sense of tactile. Using this information, human can perform dexterous manipulation. It is thought that this information is based on the skin deformation, so we aim to present the skin deformation. For the tactile display that can present skin deformation, we fabricated the three dimensional moving stage that is driven by the hydraulic pressure. We performed experiments to present shear deformation using this display system. From this experiment, it is clear that the deformation speed influences on the perception of the skin deformation. For presenting different deformation under the condition of same normal pressure, we use an air pad that can vacuum air. Using this air pad and the hydraulic display system, we performed experiments to present shear deformation using air vacuum. From this experiment, we. can present large deformation under the condition of same normal pressure.
