Abstract :
A cheap guidance system based on AT89C52 microcontroller is developed for facilitating visually impaired people. Ultrasonic sensors are used to calculate distance of the obstacles around the blind person to guide the user towards the available path. Output is in the form of voice which the blind person can hear e.g., right, left etc. In its advance mode, the system will be able to recognize objects using image processing algorithms. Results are presented to show the validity and performance of the system.
