Magic Input: A Multi-user Interaction System for SAGE Based Large Tiled-display Environment

In a large tiled-display environment, it is important to support multi-user interaction with juxtaposed applications for collaborative work. Although a few multi-user interaction systems have been developed by researchers, they often require modifications to desktop applications to become simultaneously accessible for multiple users. In this paper, we propose a novel multi-user interaction system for large tiled-display environments which needs no customizations to applications. To enable multiple users to cooperate within one application, three basic interaction strategies are introduced for different situations. Our experiment results show that this system not only enables users to interact with applications smoothly just like what they feel on their desktops but also presents them with more collaborative and immersive experience in a large tiled-display environment.
