Designing Of Navigation System for Blind People Using Gps & Gsm Techniques

Abstract

In this paper the current state of research and development on global positioning systems (GPS)-based navigation systems for the visually impaired. In this project a walking stick has been designed to help the blind person to detect obstacles and navigate towards the destination. The proposed walking stick consists of a microcontroller, infrared sensors, a GPS receiver, label surface detection, a buzzer and a vibrating motor. The detection of obstacles is done by an array of infrared sensors. The GPS receiver has been used for navigation purpose as well GSM will act as a mobile phone which informed about the danger of blind person. In order to make this stick useful for a blind as well as a deaf person a vibrating motor is used to generate vibrations near the handle of the stick to detect the presence of obstacles. This whole setup will be mounted on the cane. Every effort is being made to make this cane cheaper as well as user friendly. As the technology is advancing day to day, the human machine interaction has become a must in our daily life. The primary objective of this work is to permit blind persons to explore autonomously in the outside environment. The proposed work is to use a stick including a GPS Navigator. Now a days a stick are used with some features but in our project we are using GPS module with some other advance features. This work goes for giving the route to blind person by designing a cost effective and more flexible navigation system. The proposed system consists of hardware and software. Here the components we are using are Microcontroller, GPS module, etc. This project will help the blind people in improving their communication ability and not to depend on none during walking in even unknown areas.
