GPS BASED BLIND NAVIGATION SYSTEM FOR INDOOR



project center in Tirunelveli 


Objective of this project is helping the blind/old persons travelling easy and illiterate people as well as pedestrian people using an interactive embedded Wireless Sensor Networks. The term blindness refers to the people who have no vision at all or people who have less vision. Most of the blind people take support from guide dogs to walk. We are explaining about the GPS and voice navigation system for blind people.
In this blind people issues the commands and then receive the response using audio signals. GPS receiver is used to receive the values of the latitude and longitude continuously. With the advancement in technology usage of voice recognition is easier to send commands regarding directions to the blind people. As an application of this GPS technology here GPS based voice alert system for the blind persons are very useful, compact and simple system to handle. Today the increase in traffic cause pedestrian to the road harder. The thing is worse if a blind need to cross the road. There are many technologies developing rapidly, but for physically challenged there is not greater development. This project is developed to make the blinds cross the road safely. It consists of a micro controller and Voice controller to show the status of the signal through voice and GPS. This project is very useful for blind people in order to find the traffic signal during their travel. By using this project blind people can walk without human help.
