Design and Research of Braille Machine Control System Supported by Human-Computer Interaction

In order to meet the learning needs of the visually impaired patients, based on the tactile psychological and physiological characteristics of the visually impaired patients, this paper designs a braille machine control system. By analyzing the structural and functional principles of the braille machine, the overall flow chart of the control system of the braille machine was established, and the software program of the control system was compiled in combination with the needs of human-computer interaction and the particularity of the operating group, and the control system was used to carry out the braille test. The results showed that: Using the braille text written by the control system, its dot diameter, dot height, dot pitch and square distance are in line with national standards. And the variance of each parameter obtained by calculation is smaller than that of the national braille standard, which verifies the feasibility of the designed braille machine control system.
