Abstract: In this paper we propose a solution to the simulation of a real time deformable cloth for haptic interaction. The simulated environment consists of a deformable cloth, corners of which can be attached to a number of independent haptic devices through a client server mechanism. The users can feel the tensile force which is acting on the cloth due to its own weight through the haptic interface. A ball with a known mass is also rolled over the simulated cloth so as to effect an external force variation on the cloth. The cloth is modeled using a sufficiently dense mass spring model. A Graphic Processing Unit (GPU) is used at the server to speed up computation of cloth motion to make the computation time comparable with the haptic updation time of 1ms. We also use the environment as a possible gaming platform with several players interacting asynchronously using their respective haptics devices.
