The Future of the CAVE - Electronic Visualization Laboratory ...

focuses on future room-scale VR systems. There is much literature noting the benefits of large
displays that helps justify this focus; for example, see [Tan03, 06, Yost07].)
Someday, high-resolution 3m-by-3m 4K-resolution panel displays formed into a ceiling,
positioned vertically as walls, and tough enough to walk on, may allow CAVEs to be built in just
about any enclosed workspace, given suitable ventilation and provision for safe ingress and
egress. Today, however, a 6-sided cubic-format CAVE presents many challenges to a panel-based
implementation. As a result, less than totally surrounding panel-based systems have been
developed and installed by the authors to offer significant and usable VR imagery, given the
current technological limitations. Someday a perfect technology may emerge, such as seamless,
lightweight, high-resolution fabric or painted-on wall, floor, and ceiling coverings. Of course,
software for control and content will always be a challenge, and that is worthwhile for researchers
and developers to address while anticipating hardware advances.
The CAVE was envisioned from the outset as a device to enable distance collaboration among
viewers immersed in shared computer-generated scenes – a kind of 3D telephone booth
[Korab95, DeFanti96, Lehner97, Leigh97a, 97b, 98, 07, Johnson98, Stevens99, Park00], a
technique called tele-immersion. Much work has gone into building and optimizing ultra-highspeed
computer networks suitable for sharing Gigabits/second (Gb/s) of information across a city,
region, nation, and indeed, the world [DeFanti96, Leigh96a, 96b, 97c, Brown99, Jeong06,
Smarr06]. In fact, scientists, engineers and artists in universities, museums, and commercial
manufacturing routinely use CAVEs and variants in this manner [Pape98, Lehner97, Kooima09,
Smith00]. Today, unique forms of tele-immersion are facilitated by a 10Gb/s network link
between KAUST, EVL, and Calit2 via Amsterdam as an extension of the Global Lambda
Integrated Facility [GLIF].
