Abstract

In this paper, virtual manipulation technology is investigated for a class of virtual cockpit system. Firstly, a prototype is constructed for the virtual manipulation process. Then some of the key techniques involved in the virtual manipulation prototype are discussed respectively. These techniques include the tracking and modelling of hand, modelling of virtual objects, modelling of virtual force, motion analysis of virtual object and stable grasp condition, etc. It should be noted that, though the virtual manipulation prototype is developed for virtual cockpit system in this paper, it can also be implemented in other virtual reality systems, in which, hand's interaction with the virtual world is essential and necessary.
