Multiuser Stereoscopic Projection Techniques for CAVE-Type Virtual Reality Systems


Despite the development of increasingly popular head mounted displays, CAVE-type systems may still be considered one of the most immersive virtual reality systems with many advantages. However, a serious limitation of most CAVE-type systems is the generation of a three-dimensional (3-D) image from the perspective of only one person. This problem is significant because in some applications, the participants must cooperate with each other in the virtual world. This paper presents the adaptation of a one-user CaveAutomaticVirtual Environment (CAVE) installation in the Immersive 3-D Visualization Lab at the Gda´nsk University of Technology to a two-user stereoscopy system. Simultaneous use of two alternative one-user stereoscopies available in the I3DVL (a technique with spectrum separation—Infitec, and active stereo) and a simple electronic circuit have allowed us to transform the one-user stereoscopy CAVE installation to a two-user stereoscopic system. The experiments performed concentrated on several objective measurable parameters. The calculated crosstalk value was low, approximately 1%, which can be considered negligible and shows the proper operation of the proposed technique. Additionally, initial experiments based on the tested two-user application and related to user comfort in the developed two-user stereoscopy are discussed in this paper. However, this topic still needs further research. The proposed solutions are a cheap alternative to adapt the existing one-user CAVE-type systems which support two projection techniques to a two-user system.
