Arm7 Based Electronic Travel Aid System for Blind People Navigation and Monitoring
This paper is intended to provide overall measures –object detection and real time assistance via Global Positioning System(GPS).This paper aims at the development of an Electronic Travelling Aid (ETA) kit to help the blind people to find obstacle free path. This ETA is fixed to the stick of the blind people. When the object is detected near to the blinds’ stick it alerts them with the help of vibratory circuit (speakers or head phones). The system consists of ultrasonic sensor, Sonar sensor, GPS Module, GSM Module and vibratory circuit (speakers or head phones). The location of the blind is found using Global System for Mobile communications (GSM) and Global Position System (GPS).
