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. 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 in press button. 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.
