The fast expansion of wireless networks and mobile devices enables portable devices to join collaborative graphics design conveniently. The limitation of display size and computational power of these embedded devices makes it hard for mobile users to browse large pattern that renewed in real time efficiently. We present a novel user interest region prediction algorithm to forecast user’s intention in the near future. Related experiment was carried out to test the effectiveness of the algorithm. Results show that the algorithm can well predict mobile user’s interest regions. Based on the prediction, only sub-patterns and operations that might be interested to user are issued to the embedded sites. User study results indicate that the proposed approach is effective and the feasibility of the collaborative graphics design system in ubiquitous environment is enhanced.
