プリンタブルな大型静電触覚ディスプレイにおける基礎特性の検証

抄録

This paper proposes an electrostatic tactile paper with colored ink printed on solid electrodes, and that can express both visual and tactile stimulation. The display was constructed on flexible film, making it easy to fold and store. As a result, it was compact and portable. The display is made up of a flexible film that can be folded for storage. It is also easy to make the display larger. In this paper, we discuss the possibility of using the display to present a tactile sensation of uniform intensity over a large area. We also investigated options for the size of the contact area and examined the effect of size of the colored ink layer on perceptual intensity. The results showed that uniform presentation of tactile stimulation was possible, at least at the A3 size. We also found that sensitivity to the tactile stimulation increased when the whole hand was in contact with the display. Although the presence or absence of the colored ink modulated the intensity of the perception, the thickness of the ink layer had no effect. Our results indicate that it is possible to print vivid graphics using a sufficient amount of ink without worrying about the effect on tactile presentation. In summary, the effectiveness of both visual and tactile presentation using the proposed display was confirmed.
