abstract
We compare user-interaction and performance on a navigation and way finding task across two separate immersive displays: a low-cost, tiled, multi-screen immersive visualization system and a more expensive, continuous screen, immersive visualization facility. The low-cost system is designed with economy in mind and uses off-the-shelf components. It is constructed by arranging LCD displays in a curved tiled layout. The expensive system is a Rockwell-Collins semi-rigid, rear projected, continuous curved screen. With the low cost paradigm, physical seams are introduced into the image where the displays are tiled. In contrast the expensive system presents a continuous image. We hypothesize that the tiled system presents an equivalent visual experience, despite the physical seams introduced by connecting the screens. Both systems were tested through experimentation designed to measure performance in a navigation and way finding task. Experimental results indicate that there are no significant differences in task performance across display type, which means that for navigational tasks of this category, user performance is not impacted by the interrupted image in the tiled display. 2011 ACM.
