What is a CAVE Good For?

ynakai asks: "Today, I had the fortune to be allowed to play with demo applications in a CAVE. This technology is stunning, but what is the killer app? A staffer said that despite the potential use as a teaching tool for medical students, the system is rarely used now except by digital artists (who admittedly create some stunning experiences - try the VRML versions of some). Surely Slashdot can think up better ways to make use of a multimillion dollar room of fully immersive 3D interaction, besides FPS games?"

You would only need to cover the passenger compartment windows with screens.
Of course the animatronic backseat driving mother-inlaw could drive up costs

Then when you finally disconnect (say, after a week) for food or something, people will ask you questions about the news and when you're dumb founded cause you havn't watched tv in a week they can say "have you been living in a cave or what?" and you can say "actually, yes I have!"

Better, yeah probably, but cooler, I dunno. Also, if you were a nerd in charge of coming up with idea for applying this technology, and it was already paid for, why on earth would you give up the best gaming rig on the planet. I'm sure there are a lot of great ideas, but everyone is afraid of losing their UT03K "test lab".

There simply isn't anything about using spreadsheets or word processors today that is enjoyable. They are the epitome of redundancy and boredom.

Taking these to the 3rd dimension and immersive could make the profession of accountant and secretary more attractive to young college graduates.

Re:Spreadsheets and word processing (1)

kabocox (199019) | about 11 years ago | (#7162300)

How would taking charts, graphs, and grids of numbers into 3D make it more attractive? I think a better solution would be for hi resolution 3 or 4 ft LCD screens. It would be "cheaper" implementing it to. How many accountants or secretaries would get a CAVE system? Unless it improved productive like ten fold, not many.

Blantant Plug -- Got a CAVE -- Use Ensight! (2, Interesting)

bats (8748) | about 11 years ago | (#7159077)

My company, CEI, Inc., makes a product called EnSight that's used in CAVE environments. EnSight is a general purpose scientific visualization tool used in a broad variety of fields. Take a look at the pretty pictures on our website [] . Fields include astrophysics, professional motorsports, crash test simulations, industrial production simulation, biomedical, aerospace vehicle design, etc. Really high end visualization happens in a CAVE environment with 3-D goggles and head tracking equipment. This lets you move around through your simulation, look at things from different perspectives and even look from inside out. Most of these things are driven by big SGI boxes, but clustered (read linux) solutions are becoming more viable.

EnSight -- See what you're missing! (Please mod accordingly for cheese content.)

From working with a CAVE enviroment in a research lab for 2 years, I came to the simple conclussion that other than for developing and utilizing some custom 3D (with immersive stereo glasses, head tracking etc.) applications, and showing off your work on a big screen (with 3D of course).

There is a definate wow factor to it that helps in promoting the research, but for the most part it becomes stale fast.

Yeah, I'm with you. I worked in a lab with a CAVE for several years, and I've visited other places with CAVEs. They're mainly good for making gee-whiz demos to impress funding agencies. I have yet to see anyone actually doing real work in a CAVE.

I can think of a lot of answers... (1)

Jerf (17166) | about 11 years ago | (#7159248)

I can think of a lot of answers, but they all involve high market penetration.

Who would have guess that computers would someday be used for Instant Messaging in the 1970's? First computers have to be cheap, then penetrate the market, then get hooked up, then the software be developed, etc. I can imagine immersive setups or MMORPGs or really useful collaboration tools or all kinds of other things that require a lot of people to own the hardware or a lot more bandwidth.

Basically, if you imagine technology as a tree, CAVE is probably a dead-end stub, where a nearby branch will end up taking off and strangling the CAVE approach, probably a branch that has a much lower hardware cost. (Think digital glasses that track movement and virtually project a room; much cheaper, much easier to make useable by the 'common man' since it doesn't eat cubic feet for lunch, easier to make useful intermediate steps.)

It is not useless but until there's one in a few million homes the commercial apps aren't going to take off, and fully enclosed environments are just prohibitive in so many ways for so many people. CAVE is a great research project, don't think I'm "knocking" it, but, well, I can't think of any killer app that came from a lab. (Xerox PARC developments subsequently used by Apple don't damage that claim, they re-inforce it; until Apple repackaged it out of a lab environment GUIs were dead. Not to mention GUI isn't really intrinsically a killer app, desktop-publishing was.) Part of the reason is the fact that until we use it, we don't recognize the killer app, and few people if any can guess it in advance (which, incidentally, does mean the Ask Slashdot as asked is basically unanswerable, historically speaking).

Until we have hackers (old sense of the word) hacking on it, the killer app won't happen.

Anonymous Coward | about 11 years ago | (#7159469)

what, that needs to be spelled out any further? I don't think so.

However, why not? Now, remember that Kinkos used to flog (and I guess they still do, but am too lazy to check their website) their videoconferencing facilities, before webcams and voip were as common as they are now.

With a CAVE, you set up across the street a competing shop with a name like, oh, "Kinkies," and flog yours instead. ("Come view our womb imagery. Sugar walls, four of 'em. Have you ever been surrounded by porn? You will.")

walk-through/around (1)

Lish (95509) | about 11 years ago | (#7159559)

I think the "killer app" is being able to walk through a building that is just plans, before construction starts. Or to walk around a large object that is still in plans (eg. a plane or car) to see how it will turn out. Yeah, there's regular 3d render software that you can do this with on a small scale, but to do it life-size is something else. Especially with architectural plans.

Re:walk-through/around (0)

Anonymous Coward | about 11 years ago | (#7180268)

Parent is dead-on. Immersive visualization (such as CAVE) is extremely well suited for the construction industry. Bringing representatives from multiple disciplines together BEFORE building anything, simply to see where certain systems interface/conflict with other systems and to review the overall design - these are both highly valuable experiences. A colleague of mine used a CAVE during the building of the Walt Disney Concert Hall [] with a good deal of success.

In summary: CAVE is ideal for virtual building in the construction industry.

Jonah Hex (651948) | about 11 years ago | (#7160572)

Surely Slashdot can think up better ways to make use of a multimillion dollar room of fully immersive 3D interaction, besides FPS games?
I've never personally used a CAVE, but after looking over some of the reading material and the caveQuake site I can honestly say that I probably wouldn't be able to play FPS's in a CAVE.

The head tracking sounds good at first, until I think of how much twisting and turning I actually put my gun-toting avatars through; if I had to do that with my neck I'd either be in a neck brace or I'd be able to out-headbang Metallica. Maybe if it tracked my eye movements I'd go for controls other than my trusty keyboard and mouse, but I'd rather hit the park for some hacky-sack than to try and play some weird FPS version of Dance Dance Quake.

The other main problem I see with this is it could actually be too immersive for many gamers, perhaps myself included. I'm not especially susceptible to vertigo or motion sickness, however one of the nice things about a single large screen is that it is very immersive while you stay focused but it's also easy to maintain that level while not becoming ill.

Re:CaveQuake (1)

deanj (519759) | about 11 years ago | (#7163189)

Playing CQ is nothing like playing the one sitting down in front of a screen. You re-adjust when you're playing like this. There's no real movement, other than turning (your head or body) and ducking.

I've got motion sickness justa by sitting down in front of the screen and doing just non-stop running, and that was in Doom. You're not any more prone to motion sickness with CQ than you are with a regular screen, as long as you're the one controlling the action in CQ.

adam872 (652411) | about 11 years ago | (#7159931)

The crew I work for makes some pretty flash software for visualising oil and gas reservoirs in 3D in an immersive environment. It's not exactly the same as a CAVE, but we have variously used active/passive stereo and domes in the past to achieve pretty much that same effects (I'm sure it would work in a real CAVE too).

It never ceases to draw the "oohs and ahhs" from customers. The thing is, they actually find it useful, not just as some pretty eye candy. I guess you'd want to for the price of that SGI Onyx and the Barco projection system required to run it.

bill_mcgonigle (4333) | about 11 years ago | (#7159945)

Studying France? Take a class trip to Paris. OK, so that's too expensive, but if you can get the kids to a local CAVE they can get the walking tour and a good feel for the city.

The missing bit of technology would be something that could interpolate between QTVR nodes in a scene, to allow for arbitrary motion. Yeah, that's hard, but there are few motivators as enticing as cool hardware. :)

... for researching the effects of visual-vestibular conflict on human balance. It's basically as good as it gets for researching vision; all the affordable (not to say CAVE isn't expensive) head-mounted displays have too narrow field of view and tend to be cumbersome.

Another application I can think of is exploratory data analysis (or data mining if you prefer). You can have multiple visualizations of a large data set floating around and even go into the data. The thing is that humans are very good a pattern recogniction (though sometimes even when there are none) and CAVE could be used to exploit this in science.

Lots of things (1)

0x0d0a (568518) | about 11 years ago | (#7160677)

It's probably vast overkill, but 3d systems frequently don't lend themselves to 2d visualization that well. Take, say, a building's power system. Sure, you could pop it on someone's computer with a 3d card, but computer input devices aren't anywhere near as nice to use as actually moving over to what you want to look at.

It might be interesting in computer vision -- you can actually produce an environment to desired specifications (or over a gradient of worsening conditions) to test in.

CAVE in Linz (1)

neglige (641101) | about 11 years ago | (#7161214)

The Ars Electronica Center [] in Linz has a CAVE installation [] . I had the chance to use it on a guided tour. Graphic quality was not too great, esp. when compared with todays FPS, but the experience was really cool!

I'd say the main areas of use for a CAVE system are design and construction, for example cars or houses. Anything that needs to been seen with the spatial component but is too expensive to build as a prototype. Just imagine building a house and then having to tear it down again because in the computer room you couldn't place the surround speakers correctly...

Headset better? (1)

DrJAKing (94556) | about 11 years ago | (#7161233)

For a lot of applications headsets are probably better. When I tried the CAVE here I was blown away by the immersion, to the extent that I bashed into the wall. And that's the connundrum at the heart of the thing - if you have something so immersive, that allows you to turn around and look at the virtual environment, many uses you might have for it would involve walking. Effectively you have something halfway between 3 (rotations) and 6 (rotations + translations) degrees of freedom - you *can* translate but not far enough to do much with. A headset with a long wire gives you much more range and you can do walk-around stuff.

Re:Headset better? (1)

cr0sh (43134) | about 11 years ago | (#7177070)

Actually, there exists a walking surface that is essentially a conveyor belt that can move in both directions simultaneously - it was created for DARPA's "dismounted soldier" project (think of two belts overlapped at right angles to each other, and the belts consist of multiple rollers running parallel with the direction of travel of the belt - ie, perpendicular to the end rollers for the belts). The system also had hydraulic rams to change the incline of the "terrain", as well as motors and such to provide feedback and terrain feel changes.

Not perfect, but not a bad system for a CAVE, either...

Another fun thing would be flying! Without a plane, of course, the way Superman or the Flying Nun used to do it. In the spirit of Douglas Adams, you'd start off by throwing yourself at the ground and missing.

It also shouldn't be hard to arrange a walking tour for architecture students through a city that includes hundreds of architecturally significant buildings, from reconstructed versions of Rome's Colloseum and Circus Maximus to the Guggenheim and the World Trade Center.

Other than FPS? Training... Military... (1)

kabocox (199019) | about 11 years ago | (#7162225)

Until the games industry starts branching out into other occupations other than "lone military man behind enemy lines," driver (usually race but they are branching now alittle), pilot, or sports, then you won't find alot of use for it. What we need are games like crime scene detective, archaeologists (other than Indy).

Most outdoor type of work though would be alot cheaper performed outside somewhere. The advantage of a CAVE system is that you could have a standardized model that everyone practices or tests on though. Alot of information can be lost if artifacts aren't recovered and recorded properly. It could help for randomized digs to get proper record keeping pounded into the students heads. Sort of like how CS 1 Professors were trying to pount Hex and Binary math into our heads. Without practice, most skills fade and get lost.
