Touch representation device and method for braille reading

The invention relates to a touch representation device and method for braille reading and belongs to the field of machine and man interaction. The device comprises a main control unit, a touch exciting unit and a braille display unit; the main control unit is used for converting texts, numbers characters and the like into a specific 6-point system braille literary form, fusing finger touch position information and sending a command signal to the touch exciting unit; the touch exciting unit is used for receiving the command signal of the main control unit and generating a high pressure exciting signal waveform; the braille display unit is used for positioning the finger touch position and generating a touch action for a finger according to a touch display panel. The common characters of tests, numbers and characters are converted to the specific 6-poitn system literary form, an electrostatic touch representation technology is adopted, the blind can effectively sense the braille signs by changing the friction of the finger touching the panel, and the reading efficiency of the blind is enhanced.
