Abstract: A system to assist the guiding of the blind characterized by a modular circuit which is activated by radiation emitted by a circuit worn by the blind person. The stationary modular circuit has a radiation sensor. A trigger with analog digital functions is attached to a microprocessor which has an inlet for an amplifier attached to a speaker which generates spoken transmitted messages. The trigger has outlets connected to a sensitivity adjustment control of the device, and the amplifier carries the control for the adjustment of volume. Included in the same manner are recording and reproduction indicators for signals introduced by the microphone/tape, selectable between possible messages and capable of deactivation. The device is capable of transmission of oral messages after the activation of the circuit by the user.
