Since sometimes blind people collide against high and moving obstacles, we need obstacle-sensing function in front of the blind people. This paper proposes a method of point-to-point distance measurement using ultrasonic for excellent stick in order to detect moving and high obstacles. In this method, we apply ultrasonic wave technique to measure distance to obstacles, since it does not disturb other people. By setting two ultrasonic sensors on the stick, one for transmission and the other for reception, the moving and high obstacles are detected before colliding. Moreover, embedded systems are employed in the system in order to reduce system size and cost, as well as saving energy. In experiments (with wood, concrete, plastic, etc as obstacles), the results reveal distance measurement accuracy 95 % approximately.
