Abstract
An electronic guidance system for visually impaired persons includes a sensor for detecting the proximity and orientation of an approaching object and a microprocessor that is programmed to translate signals from the sensor into audible signals that are projected by directionally oriented speaker components into the user's ears. The system enables the user to determine the proximity, location, movement and identity of the approaching object.
