Abstract :
In the haptic rendering system that allows the force display of complex deformable objects, the coherence remains difficult because of the different refresh frequencies necessary for real-time haptic display and realistic visual display. In this paper, a time series based predict method is proposed to extrapolate the force computed by the deformable model to go beyond interactively to haptic real-time. The principle of the time series method is introduced, and then a detailed analysis and experimental verification of the approach are described and illustrated. In the experiment, our method is compared with other two extrapolation methods and shows its feasibility.
