Telepointer Motion Prediction in Real-Time Internet-Based Collaborative Graphics Editing Systems

Tracing the movement of telepointer is one of the most efficient ways to aware remote collaborators´ drawing actions in real-time Internet based collaborative graphics editing systems. However, delay jitter may occur, which will make the presence of telepointer jumpy and lead to semantic misunderstanding or operation conflicting in collaboration. This paper presents a novel algorithm that predicts the moving track of telepointer based on historical movement cases. The algorithm is tested in our prototype system and is proved that it can limit the negative impact of jitter and provide collaborators with smooth and accurate telepointer motion awareness information
