Ultrasonic Spectacles And Waist Belt For Visually Impaired And Blind Person

Abstract

One of the most common problems faced by physically challenged and disabled people is their day to day activities without any body’s help. They even face the problem to navigate their own house when no one is available in home. Here we are going to develop a navigation system for such people who are really in need of it. It effectively calculates distance of the detected object from the subject and prepares navigation path accordingly avoiding obstacles. It uses speech feedback to aware the subject about the detected obstacle and its distance. This proposed system uses microcontroller based embedded system to process real time data collected using ultrasonic sensor network.
