Nowadays CAD/CAM systems have been spreading and they are frequently used in a field of design and manufacturing. In case the discussion of the model created using the CAD software, conversations including spatial infomation such as "I want this part is more right." are often occured. If you can point the "this part" of the model which exists on real space and virtual space using a pointing device without distinction, it will become more intelligible for a everyone in the discussion. And we call this system which can point a model without distinction of space Universal Pointing system. Then, we use a mouse, FASTRAK and MicroScribe as a device for pointing object. We aim at development for the system which can point a real object or a virtual object that was reflected on the screen etc. using these three devices. Moreover, the technique as, for which an exchange of data is made to a system using TCP/IP-was proposed.
