The design principle and implementation of electronic guide dogs are as follows:

Design Principle: This technology uses infrared rays The sensor captures the infrared signal reflected by the object in front and converts it into an electrical signal for processing. The sensor continuously scans the surrounding environment and transmits the detected object information to the main control system.

Implementation method: After receiving the object information from the infrared sensor, the main control system will send out vibration signals or voice prompts of different frequencies and strengths according to changes in distance and direction. By wearing a special vibrating device or listening to voice prompts, visually impaired people can judge the location and distance of obstacles ahead and respond accordingly.
