“There are multiple smart accessories such as smart glasses, smart watches, etc. available in the market. But all of them are built for us. There is a significant lack of technology to aid the physically challenged.
I wanted to build something that is useful for the visually challenged people. So I designed a low-cost smart glass that can be used to help the visually impaired.
This project uses a few ultrasonic distance sensors, an Arduino Pro Mini, an MP3 player module, and some vibration motors. The circuit board used in this project in the form of a spectacle, which can be worn by a visually impaired person. An Arduino mounted on the spectacle will detect the obstacle with the help of the sensors and notify the user distance and direction of the obstacle through headphones and vibration motors.”
