A design of cell-based pin-array tactile display

In this paper, we propose cell-based pin-array tactile display which uses cell-based pins that express 2D-shape of character (letter, digit, etc.) in the form of line unlike general pins that offer stimulation of spot form. Human operator recognizes the information of letter or digit by scanning tactile display device's surface freely using skin tissue of user's fingertip. We examined the possibility of practical usage as small tactile display for mobile and wearable environment through implementation of device's simple model and user's test.
