<P>PROBLEM TO BE SOLVED: To provide a distance recognition system for a blind or amblyopic person to recognize the surrounding circumstances, which system has functions that (1) the person can sense the distance to an object using a distance sensor, (2) can distinguish between a plurality of distance sensors and (3) can sense a wall that located at an angle with respect to the distance sensor and (4) which has the function of compensating for a walking stick, a seeing eye dog or a navigation guidance system and (5) which is small, lightweight and portable. <P>SOLUTION: The distance recognition system has following characteristics: (1) the person can sense the distance using his or her own ears by converting the distance detected by the distance sensor to a rise or a fall in the sound of an audio frequency; (2) the plurality of distance sensors can be distinguished by using different tones; (3) the wall that is located aslant can be sensed by using three distance sensors 2, 3 and 4 having different attachment angles; (4) the system has a compensating function to understand the surrounding circumstances; and (5)the system uses microsensors fixed to a hair band. <P>COPYRIGHT: (C)2004,JPO |
