摘要：People with low vision usually use stick to find their way or to face an obstacle in front of them. However, this detection only can be felt as long as the length of the stick from its handle is as far as the reach of the hand. Seeing this limitation, a set of sonar vision was made using sonar sensor, which equipped as a wristwatch and a buckle of a belt. The sonar vision was designed to detect an obstacle for up to 3 meters away. A hundred low vision people already got the benefit of this system, which 84% of them felt that the sonar vision helped them in the navigation. The new design based on the feedback is presented in this paper, which is equipped with GPS for positioning information.
