Navigation System for Blind People Using GPS & GSM Techniques

Abstract

The aim of the project is to provide the navigation information via audible messages and haptic feedback to the visually impaired people helping them to improve their mobility independently. The system with portable self-contained feature that allows the blind people to travel through familiar and unfamiliar environment. The proposed system consists of hardware and software. In this system the Braille capacitive touch screen enables a user friendly communications with the systems. All the operations can be made with this touch screen. The major components are the GPS receiver and path detector used for receiving the current position and finding the current position and finding the shortest path to the destination. The navigation process of the system will start once the user gives the destination as voice command. The system is provided with an emergency button which will trigger an SMS that will send the present location of the user (GPS coordinates) to a remote phone number asking for help, in case emergency. In addition, the device provides user information needed, in audio format, including time, calendar, object colour, alarm, obstacle detection, navigation direction, ambient light and temperature conditions. This project will help the blind people in improving their communication ability and not to depend on none during walking in even unknown areas.
