Supporting Multiple Users in Single-Stereo-Pair Immersive Virtual Reality Environments
Jonathan Marbach
Computer Science PhD Candidate

Immersive Virtual Reality projection systems, often known as CAVEs, are large enough to support multiple concurrent users, yet most have been designed to present a single stereographic image to a single, motion-tracked user. Previous efforts to accommodate multiple users have focused on providing multiple stereo pairs through increasingly complex and costly projection hardware. Some prior work in producing a single stereo image pair for multiple users does exist, but it is not well suited to the cube-like shape of many virtual reality systems. This work proposes novel rendering techniques which attempt to improve the user experience for pairs or small groups of co-located users in single-stereo-pair projection systems. Several techniques are evaluated in a human-subjects experiment, the results of which show that presenting views from the mean head position, with or without per-user stereo-pairs, improves the user experience by significantly increasing a user's sense of presence and by decreasing the incidence of simulator sickness.
