【摘要】：基于電刺激,利用盲人對電脈沖刺激的敏感性,提出了一種盲文點(diǎn)字顯示器電路設(shè)計(jì)方案,并進(jìn)行了電路實(shí)現(xiàn)。經(jīng)計(jì)算機(jī)串口輸出的盲文信號通過解碼電路解碼為多路I/O信號,I/O信號控制脈沖發(fā)生器產(chǎn)生脈沖觸發(fā)針灸電極,盲人通過觸摸電極有無刺激感覺來識別盲文。
[Abstract]:Based on electrical stimulation and the sensitivity of blind people to electrical pulse stimulation, a circuit design scheme of Braille dot display is proposed and realized. The Braille signal output through the serial port of the computer is decoded into a multi-channel I 鈮，
