摘要

The device (1 ) for guiding a partially-sighted or blind person (X) without contact along a trajectory or route comprises a transmitter (T), comprising two transmitting antennas (A1, A2), adapted to form two electromagnetic barriers (B1. B2) perpendicular to a street plane and separated by an adjustable distance (Z) and also comprises a receiver (R) worn by the person (X) and comprising two alarm devices (Y1, Y2) adapted to generate an alarm when the person (X) gets close to one of said two electromagnetic barriers ( B1, B2).
