Developing mobile application to navigate blind people using sensors

The aim of this project is to develop the mobile application that helps to navigate the blind people using different sensors. The sensors used here are temperature sensor, ultrasonic sensor, acceleration sensor to sense the environment. Whenever the user move near a critical position, the sensor network connected to the microcontroller will senses the surrounding of the blind and passes the information to the user. The input will be acquired through voice from the blind users. The application gives response to the user through alerts. The notification will be send to the user only when the threshold value crosses the bound value. The navigation system contains GPS for finding the location. It will give user current location, distance and time calculation to reach the required destination through the voice alert. We propose an application that generate request based on user query to the system which in turn get the result from the different sensors used and send back the response to the user through mobile alerts. Thus the blind user can make independent travel.
