Abstract

In recent development and research of Virtual Reality applications, much attention has been focused on methods to provide force feedback to the human operator. Haptic plays an important role on lifelike interaction with the generated environment by computer. Whether the force interaction between virtual hand and virt ual objects is modeled accurate or not, is a rather important factor for immersing qualities of virtual environments. Here we give a novel method, which is on the basis of nonlinear contact finite element theory, to model the force interaction between virtual hand and virtual objects. This work,.first, studies the classification of force feedback, they are: force on the tool, force on the skin surface and force on the surface ofreal object, and presents corresponding mathematics model, consequently, models NURBS-based geometric fingertip and force between virtual hand and virtual objects, lists equations of resolving, which are based on nonlinear finite element theory, furthermore, the result of experiment is given with ANSYS. At the end of this paper, future research is also discussed.
