Abstract

The purpose of this project is to develop the Electronic Travel Aid for the blind people. It will involve the ultrasonic technology to be more useful and reliable compare to the classical cane in order to provide fully automatic obstacle avoidance with audible notification. Developments in embedded systems have opened up a vast area of research and development for affordable and portable assistive devices for the physically challenged. Besides, it is design to consume less power, portable in size and has an acceptable accurate performance in object distance. This project aimed at the design and implementation of a detachable unit which acts to augment the functionality of the existing white cane, to allow knee-above obstacle detection. However, due to its inherent limitation, the classical method does not provide the protection for the body. Consequently, there is no guarantee that’s the presence of obstacle, can be detected by the blind to avoid a collision. The cane developed helps a blind person find way without any difficulty in terms of improving the social life for the blind pedestrian.
