ELECTRONIC ASSISTIVE AID FOR VISUALLY IMPAIRED PEOPLE USING ARDUINO

ELECTRONICS AND COMMUNICATION ENGINEERING

This paper describes that the with the scope of electronics increasing day by day, the need for utilizing these advanced technologies to make human lives simpler is becoming more and more necessary. The demand for using these technologies to make lives easier for disabled people is also increasing. This has prompted many new areas of research and one of the areas is electronic mobility aid for blind people. There are a few smart systems available in the market which uses electronic sensors mounted on the cane but those systems also have certain disadvantages. The Electronic Guide is a device to assist visually impaired people with obstacle free path-finding. The highlight of the Electronic Guide system is that it provides simplified information on the surrounding environment and deduces priority information without causing information overload. The priority information is provided to the user through audio feedback mechanisms. The proof-of-concept device consists of a Arduino with ultrasonic sensors, infrared sensor, fire sensor, GPS, GSM and a power supply. The evaluation results show that electronic guide is a useful aid in the detection of obstacles, wet floors, and ascending staircases and its performance is better than that of a smartcane.
