Abstract
The application discloses a Braille input system and method based on a triboelectric nanogenerator, and the system comprises a plurality of TENG sensors, which are used for detecting mechanical signals generated by a user during a Braille input operation and converting the mechanical signals into current signals; a signal processing module, which is connected with signal output ends of the plurality of TENG sensors through signal input ends, and is used for performing signal conversion and coding processing on the current signals output by the plurality of TENG sensors to form corresponding characters or character strings; a signal transmission module, which is connected with a signal output end of the signal processing module through a signal input end, and is used for transmitting the characters or character strings to a target terminal; and the target terminal, which is in communication connection with the signal transmission module, and is used for outputting corresponding voice feedback messages according to the received characters or character strings. The application innovatively adopts the TENG sensor as an input device, realizes truly self-driven Braille typing, and can effectively help the blind to input and type on electronic equipment.
