| Research Abstract |
This virtual object handling system can be used for applications of interactive 3D modeling such as industrial design and field of art. For realizing direct handling of virtual object with high accuracy and really existing sensation, a special type of stylus was developed. The grip of stylus is mounted on the driving mechanism, however, the pointed end is a virtual object displayed as if united with the grip. A fast eyes positions measuring system using PSD and special graphics processor were developed for display of realistic motion parallax. This virtual pointed end enables not only direct handling, but also real time touch decision using graphics hardware. So it enables transmission of the sense of touch from virtual object by controlling the grip supporting mechanism.
