Abstract
Recent development of advanced visualization technologies enables bringing virtual reality applications to a more cost-effective, scalable, high-resolution tiled display. This paper introduces a novel interactive tiled display framework called LOTUS, which allows designers to easily compose a multi-user interactive virtual environment using XML scripts for the cluster-based tiled display system. LOTUS supports more flexible multi-user interaction within multiple virtual environments on a tiled display through the use of a mobile interface coupled with the tiled display application controller. This paper describes the design and implementation of the LOTUS framework architecture, and its use in constructing various LOTUS applications and user interaction scenarios. It then concludes with suggestions for some improvements.
