ABSTRACT:
A visual sensory aid system for the partially sighted, designed to be worn around the eyes in a manner similar to that of eyeglasses. Light incident to the image source is detected by receptors mounted on the front lens and processed by the electronic circuitry. The resulting signals, representative of the image, are transmitted to monitor areas on an interior lens that extends from beyond the periphery of one eye to beyond the periphery of the other. The right and left images displayed on the monitor areas are reversed at a high frequency in order to simulate a visual stereo effect for depth perception. Areas of the monitors corresponding to blind spots of the eye are electronically inactivated. A feedback system maintains the focal point of the eye in the optimum direction.
