The haptic rendering for virtual hand interaction is a hot research issue in the field of virtual reality. Based our previous research, we integrated four aspects of the haptic rendering for virtual hand interaction, which included the contact, static grasp, movement, and collision of virtual hand. We presented a method of contact force rendering of virtual hand based on the human fingers? force characteristics. A physically-based method for generating virtual hand grasp force was proposed to simulate the force of virtual hand static holding objects. Then, we deduced the algorithms to generate the realistic action force of the virtual hand grasping an object and moving in virtual environments. The algorithms were based on the kinematics and dynamics of the robot theory. With the impulse theorem and coefficient of elastic recovery, we further analyzed the collision force rendering with friction for virtual hand interaction in virtual environments. A special series of experimental results showed that the physically-based haptic rendering approaches for the virtual hand interaction were computationally efficient while retaining a well level of realism.
