This paper presents a wearable obstacle avoidance system for blind people to navigate safely using cane and eyeglass methods. In cane method, an ultrasonic sensor is placed in cane which detects the obstacle in the ground level. In eyeglass method, an ultrasonic sensor is used which detects obstacle above the head up to certain angle. The information obtained is informed to users using audio messages and also by sense of feel as vibration in case of born both deaf and blind. These algorithms are implemented using MP Lab and Proteus tools.
