Smart Navigation System for Visually Impaired
Abstract— The life of blind and visually impaired people is very different. They face many challenges when moving in unfamiliar public places. In this paper, we introduce a smart stick system for assisting blind people. The system consists of ultrasonic sensor, proximity sensor, infrared sensor, water detector, GPS and GSM module, buzzer as well as vibratory and audio signal circuits. An obstacle detector is used to help the user to avoid obstacle by sending an audio message. The system design uses GPS and GSM module through which their family members can track their location easily if they are lost.
