Advanced voice based blind stick with voice announcement of obstacle distance

Abstract:

The main aim of this project is to assist the blind persons without the need of another person. It is well known that the blind people carry a hand stick with them whenever they need a support. Sometimes even when they use this stick, there is no guarantee that the blind persons are safe and secured in reaching their destinations. There may be an obstacle in their path but is not encountered by the person with the help of the stick. Thus, the people may be injured if the obstacle is big enough or dangerous. Thus, a design has been developed to assist the blind and provide them a clear path.

Now a day’s so many useful technologies are coming out to make our life style more comfort, luxurious and secure. In this project we use ultrasonic module to detect the object and ARM7 micro controller to play distance through voice alert.
