Tactile display which presents shear deformation on human finger

This paper proposes a new tactile display to present shear deformation to the skin of human finger. For presenting the shear deformation of the finger, we fabricated a three-dimensional moving stage driven by the hydraulic actuators. For presenting different deformation under the condition of the same normal pressure, we used an air suction pad that can suck air. Using this air pad and the hydraulic display system, we performed experiments to present shear deformation. From these experiments, large deformation was achieved under the condition of the same normal pressure.
