Abstract
We have proposed a tactile display for grasping handle using rotating round slices. This method intends to display pressure from handle and may have the ability to induce proper grasping force intuitively. We cut the handle into thin round slices, and rotate them. Directions of the adjacent rotations are set opposite with each other. The intervals of the slices are set smaller than the resolution of directional stretch sensation (by Ruffini ending). Therefore we cannot perceive the direction of rotation, while we may perceive pure pressure. In this paper, we manufactured a full size handle with rotating round slices, which is grasped by the whole palm. We evaluated relationship between the sensation and rotation parameters, such as frequency and amplitude of the rotation and slice width.
