Abstract:

The vlrtual-hand technology is a promising human-computer interaction technology. In this paper, a virtualhand model is established by the object-orie nted method, and the algorithm of motion-mapping between a human hand and a virtual hand is proposed. Then a virtual-hand prototype system is developed   by using Open Inventor as the software platform and using a data glove and a motion tracker as the input devices. Interaction between a human hand and a  virtual hand can be implemented directly, and some virtual manipulations can be accomplished naturally and efficiently in this prototype system.

Key words: virtualhand, object-oriented, human-computer interaction, motion mapping
