THIRD EYE FOR BLIND PEOPLE BASED ON ARDUINO

Abstract

From the survey by WHO, 39 million people are blind all over the world. the existing methods that merely assist them are not just enough. What they need are alternative methods by which they can navigate with greater comfort, speed, and confidence. 

By taking these into consideration, two usable prototypes have been designed that work with echolocation technology that can solve existing road problems. Ultrasound sensors are used to detect obstructions. The sensors are interconnected with the Arduino for processing purposes. Thus, there is hope for the visually impaired to pass without injury.

Where it works to alert the blind person in the event of an obstacle by giving an audio warning to avoid the obstacle. They can simply use the models that were manufactured such as glasses or a stick that can work very accurately. The only thing required is some training to use as it is easy to manufacture and low cost to be accessible to everyone.
