Remote Move-Related Operation Awareness in Real-Time Internet-Based Collaborative Graphics Design Systems

Supporting awareness of other cooperators is an idea that holds promise for improving the usability of real-time distributed collaborative graphics design systems. However, network jitter may cause serious problems in providing real-time awareness information such as monitoring the remote motion of objects or the control points of objects in such Internet-based designing system. Halting and jumping presence of remote move-related operations may occur. In this paper, we present novel algorithm and scheme that can improve the move-related operation display performance of accuracy and smoothness. Experiments were carried out to test the effectiveness of the scheme and the algorithm. The results show that by applying effective remote motion prediction and introducing jitter buffer, the usability of the system can be greatly enhanced.
