PROBLEM TO BE SOLVED: To solve the problem of a conventional visual sense assisting appliance incapable of sufficiently proving the effect of walking assist. SOLUTION: A foot detector 1 is so formed that ultrasonic road surface height sensors 4 and 14 measuring the road surface heights HR and HL from the soles to the road surface and ultrasonic obstacle distance sensors 5 and 15 measuring the obstacle distances DR and DL to the front obstacle are mounted on sensor parts 3 and 13 of the left/right shoes, respectively, and the left/right road surface heights HR and HL are exchanged via high frequency current from pushing electrodes 6 and 16 through the human body. The information is processed by circuits 9 and 19, and the road surface height and the obstacle distance are sensed to a person by intermittent periods of tapping devices 10 and 20 intermittently and lightly tapping the left/right of the feet 11. When the road surface height sensor 4 senses the raising of the right foot, a succession action is started. This device allows the raised foot to recognize the obstacle distance of the foot by tapping and allows the other grounding pivot foot to recognize the road surface height by the tapping so that the person can safely walk while recognizing the state around the feet. |
