【摘要】：基于电刺激,利用盲人对电脉冲刺激的敏感性,提出了一种盲文点字显示器电路设计方案,并进行了电路实现。经计算机串口输出的盲文信号通过解码电路解码为多路I/O信号,I/O信号控制脉冲发生器产生脉冲触发针灸电极,盲人通过触摸电极有无刺激感觉来识别盲文。
[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，
