Abstract

Haptics is a recent enhancement to virtual environments allowing users to `touch' and feel the simulated objects they interact with. Current commercial products allow tactile feedback through desktop interfaces (such as the FEELItTM mouse or the PHANToMTM arm) and dextrous tactile and force feedback at the fingertips through haptic gloves (such as the CyberTouchTM and the CyberGraspTM). Haptics VR programming requires good physical modeling of user interactions, primarily through collision detection, and of object response, such as surface deformation, hard-contact simulation, slippage, etc. It is at present difficult to simulate complex virtual environments that have a realistic behavior. This task is added by the recent introduction of haptic toolkits (such as GhostTM or VPS). Current technology suffers from a number of limitations, which go beyond the higher product cost of haptic interfaces. These technical drawbacks include the limited workspace of desktop interfaces, the large weight of force feedback gloves, the lack of force feedback to the body, safety concerns, etc. Not to be neglected is the high bandwidth requirement of haptics that is not met by current Internet technology. As a result it is not possible at present to have a large number of remote participants interacting hapticly in a shared virtual space.
