In this investigation, we studied the utilty of electric or mechanical stimuli as visual substitutes. We used mechanical and electric stimuli to present characters and colors respectively. For the reduction of learning time and the increase of recognition rate, we devised an apparatus which is connected to a microcomputer and can present Japanese sentences, including Chinese characters, with a 10 × 10 array of 100 vibrators.Color recognition is achieved by using electrical stimuli. Electric stimuli were given with two Ag-AgCl electrodes attached to the root of middle finger. Long pulse (feels warm) stands for red, short pulse (feels cold) stands for blue and a sequence of 10 pulses per second (feels like twitter) stands for green. The current value was 200 μA.<BR>In this investigation, we examined 25 subjects. The recognition rate was 100% for most three color (red, blue and green) .
