Third Eye for Visually Challenged Using Echolocation Technology

The millions of people in the world whose vision is not perfect and they wear glasses. But for those hundreds or thousands who are blind, 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, a wearable prototype is designed using Echolocation Technology which can resolve the problems of the existing methods. Sensors like Ultrasonic Sensors and IR sensors are used for obstacle detection and water detection. All the sensors are interfaced with Arduino UNO for processing purposes. Thus, there is hope for the visually challenged people to traverse without a stick. They can simply wear the designed prototype as a headset or a cap which can work very accurately and the only thing required is some training to use it.
