CAVE 기반 가상현실 최신 연구 동향

The CAVE, which was first developed in 1992 at the University of Illinois Electronic Visualization Laboratory in Chicago, is named by using a recursive abbreviation for Cave Automatic Virtual Environment, and refers to an immersive virtual reality environment created by projecting virtual scenes onto the walls of its cube-shaped room. Initially, the walls of CAVE were composed of projection screens, but with the development of display technology, flat panel displays are employed recently. In this environment, a computer-generated virtual three-dimensional space is displayed to the user through the walls. Due to wearing special glasses equipped with a tracking device, the virtual environment shown on the wall displays the three-dimensional scene interactively according to the movement of the user. Moreover, the speakers placed at various angles in the CAVE provide a three-dimensional sound, assisting the three-dimensional presence effectively. In this study, we review the history and recent research trends of CAVE, and explore its future.
