A Hybrid Interaction Method with Virtual Hand

In this paper, a novel solution combing heuristic constraints with physical-based method for virtual interaction is proposed. With which, a grasping simulation is divided into three stages including pregrasping, preliminary grasping and stable grasping and the two techniques have been used in different phases. A dexterous virtual hand, consisting of geometric model, kinematics model, collision model and contact force model, is also constructed to be used in this solution. By analyzing the physical structures and perceptual characteristics of human finger, a haptic rendering algorithm is presented to obtain natural and stable virtual interaction.
