  • Patent number: 4212116
    Abstract: An apparaus to improve the mobility of a visually impaired person comprises first and second exciter systems placed on either side of the person and acting to produce light beams which are received by corresponding first and second receivers, and first and second sound devices each with the corresponding associated receiver to produce a distinctive sound when the light beam is interrupted before getting to the receiver. In a preferred embodiment, the apparatus includes a cane held by the person so that as the cane is moved into the path of the light beam, the light beam is interrupted. The sounds, or lack thereof, which accompany the movement of the person and/or the cane provide an indication to the person whether the cane is being used properly and/or whether the person is walking in a straight line, e.g., between the light beams.
