General blind person does not afford to do.
For approach two, be to utilize ultrasonic wave or sound wave to run into the sound that barrier back reflection returns to remove judgement faceThe size of front object and the distance of distance: the eyes of bat are invisible, it is to launch on one's own account ultrasonic wave,After running into barrier above, return to ultrasonic wave, the system of accepting of bat is accepted ultrasonic wave and again according to ultrasonic wave againSize and the distance of echo disturbance in judgement thing far and near. Female of Chinese Central Television's " defeating impossible column "Scholar abandons to her from the little father and mother of losing the sight of both eyes, and is brought up by grandmother, trains for a long time through grandmother, and she can be with soundTonal discrimination barrier, can walk freely, before distinguishing that before the lights two people's height sizes and the position of standing areRear still left and right, she claps the hands or sounds with mouth with hand by controlling oneself, and treats that sound runs into barrier and returnsThe sound returning goes the size of disturbance in judgement thing and the distance of distance. Here it is utilizes the side of ultrasonic wave and sound waveMethod.
For approach three, be applying electronic light sensation device (photo resistance or photodiode, phototriodeDeng), utilize light intensity magnitude that illumination returns on different objects different and produce different light-sensing signals,Become audio signal through oscillator again and deliver to earphone, blind person sends different sound by earphone and removes to distinguish faceThe front size of object and the distance of distance.
