Design of Braille Display System Based on Piezoelectric Actuator Array

Abstract:

According to the situation that conditional Braille book is difficulty in publication and its amount is small. This paper puts forward a tactile display system which can transform content of common e-book to Braille information, and the blind comprehend the text by touching the Braille formed by the tactile display device. This Braille tactile display system extracts Chinese characters by OCR technology. The text recognized is segmented into word blocks according to the rule of Braille word segmentation before transforming to double-phoneme mandarin Braille. It uses dsPIC30F2010 to receive Braille signal and then controls the piezoelectric actuator array to output corresponding displacement.
