Real-time virtual hand controlling using OpenSceneGraph

Abstract

Recent decades have witnessed a dramatic increase in the popularity of virtual hand. And virtual hand interactions play an important role in the virtual reality like virtual assembly. In order to real-time control the virtual hand in the virtual environment. We firstly present the creation of virtual hand, including the polygonal modeling, the structuring of the database hierarchy and creation of degree of freedom (DOF) nodes. And also we demonstrate an approach for realtime control of virtual hand using OpenSceneGraph (OSG) by finding and manipulating DOF nodes and updating scenes using callback functions techniques. The driving data comes from the data glove collected. And the result shows that our virtual hand model has good kinematics properties and the real-time control proves successful.
