【 摘 要 】

Problem statement: We revealed the reason behind a haptic illusion called the Velvet Hand Illusion (VHI) by FEM analysis. In VHI, a person rubs his/her hands together on both sides of wires strung through a frame and produces the sensation of rubbing a very smooth and soft surface like velvet. We focus on VHI to determine the specifications of an actuator for a tactile display enhanced by VHI. Approach: A simulated fingertip was modeled under the same contact condition that an actual finger was believed to undergo when under VHI. We collected the simulated responses of a number of SAI afferents, which were responsible for detecting the edges, to relate them to the mechanism of the illusion. Results: Even with a simple model that treats only one finger, we noticed a considerable difference between the responses of a number of SAI receptors compared with that of a fingertip touching wires without the effect of the opposing finger. The SAI responses for the VHI case are less (some receptors
