Developments in CAVE Research
The biggest issues that researchers are faced with when it comes to the CAVE are size and cost. Researchers have come up with a derivative of the CAVE system called ImmersaDesk. With the ImmersaDesk, the user looks at one projection screen instead of being completely separated from the outside world, as is the case with the original CAVE. The idea behind the ImmersaDesk is that it is a single screen placed at a 45-degree angle so that the person using the machine has the opportunity to look forward and downward. The screen is 4’ × 5’, so it is wide enough to give the user the width that they need to obtain the proper 3D experience. The 3D images are produced by using the same glasses used in the CAVE. This system uses sonic hand and head tracking, so the system still uses a computer to process the users’ movements.
This system is much more affordable and practical than the original CAVE system for some obvious reasons. First, one does not need to create a "room inside a room". That is to say, one does not need to place the ImmersaDesk inside a pitch-black room large enough to accommodate it. One projector is needed instead of four, and only one projection screen. A computer as expensive or with the same capabilities necessary for the original CAVE is not needed. Another thing that makes the ImmersaDesk attractive is that since it was derived from the original CAVE, it is compatible with all of the CAVE’s software packages, libraries and interfaces.

Famous quotes containing the words developments in, developments, cave and/or research:
“The developments in the North were those loosely embraced in the term modernization and included urbanization, industrialization, and mechanization. While those changes went forward apace, the antebellum South changed comparatively little, clinging to its rural, agricultural, labor-intensive economy and its traditional folk culture.”
—C. Vann Woodward (b. 1908)
“I don’t wanna live in a city where the only cultural advantage is that you can make a right turn on a red light.
Freedom from labor itself is not new; it once belonged among the most firmly established privileges of the few. In this instance, it seems as though scientific progress and technical developments had been only taken advantage of to achieve something about which all former ages dreamed but which none had been able to realize.”
—Hannah Arendt (1906–1975)
“Do you know how poetry started? I always think that it started when a cave boy came running back to the cave, through the tall grass, shouting as he ran, “Wolf, wolf,” and there was no wolf. His baboon-like parents, great sticklers for the truth, gave him a hiding, no doubt, but poetry had been born—the tall story had been born in the tall grass.”
—Vladimir Nabokov (1899–1977)
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
