Prototype of a tactile display capable of presenting the material sensations of many materials by winding and unwinding real materials

Abstract

In this paper, we fabricated a prototype of a grasping-type tactile display that can hold 30 kinds of materials and presents material sensation by moving the materials according to the tracing motion. First, we developed a mechanism that can compactly store many materials by winding a tape to which materials are attached on a rotor and feeding the tape out by rotation. Next, we implemented two functions. One is predicting the next material to be touched, the another is moving the material according to the tracing speed of the finger. Finally, we discussed the contents of the evaluation experiment.
