Abstract

Haptics rendering plays a very important role in improving immersion in virtual world. As humans are more sensitive to small haptic discrepancies than visual ones, good force rendering requires a refresh rate of 500Hz or more. This paper decouples visual and haptic channel by proposing a moving Gaussian process window (MGPW) estimation algorithm to identify the haptic model online. Then a multirate real time display system can be achieved in order to satisfy human´s visual and haptic sensation bandwidth constraints separately. Experimental results verified that the proposed method
