This simple & lightweight glove will help visually impaired people to sense their surroundings with a quick response rate.

This project is based on Time of Flight sensor. Visually impaired  people generally use stick in outdoor but in indoor condition stick is not convenient specially to detect a obstacle just in front of him or horizontally. This project is not the direct replacement of stick rather it will help blind people to detect object in front of him. Laser sensor is much faster than sonar sensor so its response time is faster. In this project when a obstacle is detected a vibration motor began vibrating by which visually impaired people can understand a obstacle has been detected. A small lithium ion battery has been in this device and user can charge it using any micro usb cable or mobile charger. Power consumption of this device is very low.
