Collaborative View Configurations for Multi-user Interaction with a Wall-size Display.

This paper explores the effects of different collaborative view configuration on face-to-face collaboration using a wall-size display and the relationship between view configuration and multi-user interaction. Three different view configurations (shared view, split screen, and split screen with navigation information) for multi-user collaboration with a wall-size display were introduced and evaluated in a user study. From the experiment results several insights for designing a virtual environment with a wall-size display were discussed. The shared view configuration does not disturb collaboration despite control conflict and can provide an effective collaboration. The split screen view configuration can provide independent collaboration while it can take users' attention. The navigation information can reduce the interaction required for the navigational task while an overall interaction performance may not increase.
