The Cave: Audio Visual Experience Automatic Virtual Environment

June 1992/Vol.35, No.6 | Carolina Cruz-Neira, Daniel J. Sandin, Thomas A. DeFanti, Robert V. Kenyon, John C. Hart
The CAVE (Audio Visual Experience Automatic Virtual Environment) is a novel virtual reality interface designed to enhance user immersion and suspension of disbelief. It consists of a room with walls, ceiling, and floor covered by display screens, creating a 360-degree visual environment. The CAVE overcomes many issues faced by other VR systems, such as limited field of view and viewer-centered perspective, which are crucial for effective visualization. The CAVE's design is based on four main paradigms: Cathode Ray Tube (CRT), Head-Mounted Display (HMD), Binocular Omni-Oriented Monitor (BOOM), and CAVE itself. Each paradigm has its strengths and weaknesses in terms of field of view, panorama, viewer-centered perspective, body representation, and intrusiveness. The CAVE provides a full 360-degree field of view, supports smooth viewer rotation, and allows multiple users to interact in the same environment without significant hardware duplication. The implementation of the CAVE involves complex calculations for viewer-centered perspective projections, deployment of viewer tracking equipment, and synchronization of displays. Challenges include lag in viewer tracking, green channel issues due to phosphor decay, and multiprojector stereo synchronization. Despite these challenges, the CAVE offers superior performance in field of view, visual acuity, and lack of intrusion, making it a promising tool for collaborative visualization. Applications of the CAVE at the SIGGRAPH '92 Showcase include weather visualization, brain surgery planning, fetal development simulations, vector field visualization, fractal exploration, and biological modeling. Further research is needed to address hardware limitations and to quantitatively evaluate the effectiveness of VR interfaces.The CAVE (Audio Visual Experience Automatic Virtual Environment) is a novel virtual reality interface designed to enhance user immersion and suspension of disbelief.
