Abstract
In the virtual reality context, the use of haptic rendering as an additional sensory modality significantly improves the degree of realism of virtual worlds. The physical realism of the interaction between the user and the objects of the virtual world is particularly important when dealing with contact or collision between rigid objects as, for example, in assembly tasks. The high frequency rates required for smooth manipulations are often difficult to reach, in particular for rigid bodies simulations. Hence, we propose a new coupling scheme based on a dynamic subset of the virtual world, a localized Haptic Sub-World, running at a higher frequency than the rest of the virtual world. This Sub-World, located around the virtual object manipulated by the user, is synchronized with the virtual world through a dynamic analysis of the interface between the two subsets. Using this coupling scheme in our software environment, we are able to achieve high frequency haptic rendering using sophisticated simulation methods on virtual worlds with a large number of rigid bodies.
