Topical system-technical solution for orientation of the blind and visually impaired

In the paper problems of creating technical means for orientation of the blind and visually impaired are discussed. On the basis of the, interdisciplinary approach a spatial-distributed structure of orientation system that consists of stationary and portable devices has been offered. Stationary devices are placed along the proposed route of movement of a man in places where one need to take decisions, and include an infrared sensor for finding direction of movement and an UHF-transmitter for reporting information about location. The portable device is a radio receiver-decoder for receiving messages and a device for individual voice warning.
