Abstract
This paper describes a system for virtual object manipulation with a virtual hand. It is necessary that we be able to grasp, move, and release virtual objects with the hand similarly to real ones in order to have experiences in various virtual worlds. Therefore, we developed a new model for object manipulation with a virtual hand. Basic hand actions such as grasping, moving, and releasing are implemented and gravity and inertia are introduced in a simplified way in the proposed model. The objects are naturally moved with interactive rate in a picture generated by the graphics workstation. © 1999 Scripta Technica, Syst Comp Jpn, 30(11): 22–32, 1999
