CAVE2 is a system of 72 stereoscopic liquid crystal display panels that encircles the viewer 320 degrees and creates a 3D environment.
CHICAGO — Take a walk through a human brain? Fly over the surface of Mars? Computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality with a wraparound virtual world where a researcher wearing 3D glasses can do all that and more.
In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, conveying a dizzying sense of being able to touch what’s not really there.
As far back as 1950, sci-fi author Ray Bradbury imagined a children’s nursery that could make bedtime stories disturbingly real. “Star Trek” fans might remember the holodeck as the virtual playground where the fictional Enterprise crew relaxed in fantasy worlds.
