This paper presents a new mechanical pointing device for positional data acquisition. Since human-friendly welfare systems are seriously desired around the world, we have developed a device to aid physically handicapped persons. Our device can be used anywhere and anytime because it is rarely affected by such environmental conditions as light and noise. First, we describe the mechanism of our proposed pointing device, and explain its basic principle of coordinate acquisition. Next, we propose a concrete pointing procedure that indicates a desired object and a calibration method to obtain the accurate coordinates from points pointed at. Then, we show the experimental results of the pointing device and confirm that it can accurately acquire the coordinates of a desired object. Finally, we conclude with the usefulness of the pointing device and indicate future work.
