静電気力触覚ディスプレイを用いた複数指による触図の識別率調査

The purpose of our research is to develop an electrostatic tactile graphics display for visually impaired to read figures. We have evaluated our tactile graphics system that displays a tactile sensation based on a user’s single finger movement. However, the result showed that it was difficult for the user to capture the shapes of figures correctly. In this paper, we proposed an electrostatic tactile graphics display with multi-finger and evaluated how accurately the user can recognize the figures. For our evaluation experiment, we printed four figures with silver nanoparticle ink. The result showed that the user can capture the outline of graphics more correctly with multiple fingers than with a single finger.
