This paper is intended to provide overall measures –object detection and real time assistance via Global Positioning System(GPS) and Global System for Mobile communications (GSM).This project aims Walking safely and confidently without any human assistance in urban or unknown environments is a difficult task for blind people. Visually impaired people generally use either the typical white cane or the guide dog to travel independently. Although the white stick gives a warning about 1m before the obstacle, for a normal walking speed of 1.2 m/s, the time to react is very short (only 1 s).The stick scans the floor and consequently cannot detect certain obstacles (rears of trucks, low branches, etc.).Safety and confidence could be increased using devices that give a signal to find the direction of an obstacle-free path in unfamiliar or change in environments. Electronic travel aids (ETAs) are devices that give off a warning by auditory or/and tactile signals when an obstacle is in the way and allow the user to avoid it. 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).
