Braille recognition device by electrotactile

摘要

(purpose);When a blind person tries to write with a braille device, it is desirable that the device be made as small and light as possible and no noise is generated. For this purpose, we devised Braille recognition device by electric stimulation.;(Configuration);Braille is a means by which a visually impaired person recognizes text information such as books and magazines. As a method of generating and recognizing the pattern, there can be adopted a method of generating a projection by a paper or the like, the generation of a mechanical protrusion, a protrusion by a small hole by a mechanical vibrator, or a thermal stimulation method by heat and laser. There is a case where it becomes large-sized, a noise is generated, and it is inconvenient to carry, which may hinder the poisoning. To solve this problem, we devised a method by electric stimulation.
