A novel micro-vibration actuator using a shape-memory alloy (SMA) wire is being developed for the presentation of tactile sensations to a human skin. In this study, the SMA wire is arranged two dimensionally to construct a compact Braille display for the blind. The display is driven by electric current pulse for mobile use to present Braille information. The display was evaluated in a school for the blind, and the results are presented in the paper.
