A Novel Approach to Object Detection and Distance Measurement for Visually Impaired People

This paper describes the implementation of short range Object detection and distance measurement device with sensors for blind people. By using an ultrasonic transducer pair for producing ultrasonic sounds and sensing the reflected sound waves, the obstructions (objects) are detected. Distance measurement is used in a large number of applications such as robotic movement control, vehicle control, blind people walking stick, medical application, etc. Where this paper is focusing on enhancement of blind people walking stick device which help blind people to help themselves in this world. The measured distance data is converted to digital data for the display and sound waves so the user can get the direction of the object and distance between user and object.
