Interactive Systems

Large Displays

V4-Space is the Vancouver Versatile Virtual Reality and Visual Analytics Wall & CAVE, built in 2016. It was funded through an NSERC Research Tools & Instruments grant, with W. Stuerzlinger as principal investigator, B. Riecke, R. Woodbury, and S. DiPaola. V4-Space consists of seven 85" high-end 4k displays in portrait mode, driven by a single Windows computer with two nVidia M5000's. The single contiguous 8m x 2m display shows 15k x 4k pixels at 60Hz, hardware-synchronized.

Large Display Interaction

One aspect of this research focussed on a new kind of laser-based pen input device for large displays that supports multiple simultaneously active users. Our multi-user laser pointer input technology provides a basis for collaborative, shared display groupware for computer supported cooperative work applications. The interactive system was called MULTI (Multi-user laser table interface) and consists of a table and several wall surfaces, enabling collaborative work by teams of 2-10 people with interdisciplinary backgrounds. Another part investigated the performance of various remote pointing devices, including mice.
