摘要
Disclosed is a haptic simulation system and method for providing real-time haptic interaction in the haptic simulation system which allows a user (avatar) to feel an effect followed by a collision between the avatar and a surrounding virtual object in the form of a real-time haptic interaction through a haptic simulation device while the user performs a computer simulation. The simulation method includes the steps of: (a) operating an avatar within a virtual environment depending on a motion of the user in a haptic device while performing a haptic simulation; (b) perceiving a collision information of when the avatar of the user collides with an object of the virtual environment; (c) computing force/torque on the collision information on the basis of physical dynamics; (d) when the processing time of the step (c) exceeds a prescribed time, computing force/torque on the collision information using an interpolation method instead of the physical dynamics-based processing; and (e) transferring the force/torque values computed in the steps (c) and (d) to the user haptic device to provide the user with the haptic interaction.
