Virtual reality (VR) can be defined as interactive computer graphics that provides viewer-centered perspective, large field of view and stereo. Head-mounted displays (HMDs) and BOOMs™ achieve these features with small display screens which move with the viewer, close to the viewer's eyes. Projection-based displays [3, 7], supply these(More)

A room-sized, walk-in virtual reality (VR) display is to a typical computer screen what a supercomputer is to a laptop computer. It is a vastly more complex system to design, house, optimize, make usable, and maintain. 17 years of designing and implementing room-sized ''CAVE'' VR systems have led to significant new advances in visual and audio fidelity.(More)
The Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC) has partnered with dozens of computational scientists and engineers to create visualization and virtual reality (VR) devices and applications for collaborative exploration of scientific and engineering data. Since 1995, our research and development activities have(More)
Researchers at the University of California, San Diego, have created a new, relatively low-cost augmented reality system that enables users to touch the virtual environment they are immersed in. The Heads-Up Virtual Reality device (HUVR) couples a consumer 3D HD flat screen TV with a half-silvered mirror to project any graphic image onto the user's hands(More)
systems generate frame-interleaved video for stereoscopic equipment. Integrating LCD shutter glasses, high-end graphics computers, and large-scale projectors is difficult. This paper identifies problems discovered as part of our VR efforts at the Electronic Visualization Laboratory (EVL) and offers solutions. Common Problems There are four problems commonly(More)
