Psion (2244) | more than 5 years ago | (#26173409)

Well, that's nice, but the location of the screen is fixed. So you have a really great, 3D display, but it sits on a desk in front of you. Properly configured, VR goggles might give you a lower resolution directly in front of your face, but that resolution can scroll over a much larger area. Look to your left and you see a 640x480 view into a document you're referencing ... face forward and you can return to the new document you're writing ... and to your right is the hot chick stripping on her webcam-- I mean, the 3D model you're making. I agree that I'd rather have higher resolution than 640x480, but a lot can be accomplished with such a small screen size if your head and body movements are factored in.

Re:VR goggles, eh? (1)

mr_mischief (456295) | more than 5 years ago | (#26173683)

640x480 right in front of your face at an extremely small dot pitch offers a pretty nice field of view, too. It's not like this is 640x480 at 22" diagonal three feet away. The pixels are really tiny. Higher resolution might be nice, but it's not as necessary on this size of display.

JWSmythe (446288) | more than 5 years ago | (#26174257)

    He was talking about 3d glasses, if I recall correctly.

    But, for a while I used a pair of Sony Glasstron (PLM-A35) glasses. I had gone out to a worksite that was "suppose" to have a crash cart. They didn't. So I'm sitting there with a dozen servers, no monitor or keyboard, and no way to set the IP's when they finally do provide them.

    We went shopping, and found this crappy little store that had the glasses for like $200, or a 14" LCD screen for $400. This was a while ago. Since we were out of town, "what will fit in my luggage" was actually a big concern.

    It didn't have VGA inputs, so I got a VGA to RCA adapter, and started working. People at the datacenter got a kick out of it. I was sitting on the floor, keyboard in my lap, apparently staring off into space. :) The best part was, it fit nicely in my laptop bag.

    The extra cabling I had to tote around was a little annoying, but I could do an overnight trip with just my laptop bag and not have to check any luggage. This was pre-911. Since then, I have to check a bag just to bring a screwdriver. {sigh}

The model you're linked doesn't specify compatibility, though it does list its inputs:
VGA / SVGA / XVGA Input: Scaled to SVGA (800 x 600)

It 'might' work out of the box like a plug and play monitor but it also may not.

The best way to check on Linux support is to contact the manufacturer of the devices you are looking at.

Custom drivers can be made for linux but it is easier for people to do so with the cooperation of the original developers.

As to how feasible it is to get the Mac-based drivers to work on Ubuntu, you've got me there. I'm not familiar enough with the differences between the two OSes at that level (networking geek, not a programmer).

Nursie (632944) | more than 5 years ago | (#26173185)

There are a whole bunch of solutions for this, I looked at them a while ago, they're really cool.

They either take as input a composite video signal or straight VGA. Should be no problem treating them as a generic display from Linux.

3D is a different proposition. I don't think that's what the original question is about though, even if it is phrased as "VR googles".

fuzzyfuzzyfungus (1223518) | more than 5 years ago | (#26172683)

There are, now that small LCDs have gotten cheap, numerous "display glasses" type products that toss an LCD in front of each eye and have some sort of video input(generally VGA or composite, sometimes both or other). Basic VGA-in display glasses should work exactly like any other monitor on virtually anything. No guarantee that the EDID isn't complete nonsense; but it should basically work.

Any sort of OMG Stereoscopic Vision! drivers, though, will probably be useless in Linux. Those guys [prnewswire.com] claim to support stereoscopic shutter glasses under certain conditions; but seem to be aiming at the Real Serious Workstation market. If you can deal with normal, non-3D glasses, you should have no problems, 3D, possibly not so much.

If you get rid of the cool factor as a prerequisite, I'm sure a bored programmer could take a cheap webcam (or two) and mount them to those tiny VGA display glasses.

I was actually messing around with that idea for a while, unfortunately I was hindered from putting my plans into practice due to the cost of good VR headsets. What I was going for was a setup with three or four small webcams, two regular ones and one or two modified to act as IR cameras, a few IR LEDs to provide illumination when needed and then trying to integrate the whole thing with various pieces of hardware and software. One idea that didn't seem too hard to get working was maps + GPS displayed in 3D, sort of a poor man's Google Earth strapped to your head.

Should be Standard VGA, No? (2, Informative)

camperdave (969942) | more than 5 years ago | (#26172709)

VR goggles are nothing more than miniature displays that are mounted on eyeglass frames, so I doubt there'd be a compatibility issue, per se. You may have to get your hands deep into the xwindows config files to fine tune things, though, because they likely won't be set up already. Apart from that, they should just appear to be a standard VGA display, I would think.

Re:Should be Standard VGA, No? (2, Informative)

N1ck0 (803359) | more than 5 years ago | (#26172923)

Normally dual displays just expand the size of the viewing area from one camera point. To have stereoscopic support 3D images need to have 2 viewing cameras setup, at a slightly different offset; viewing the same object from different angles.

So a dual monitor desktop still has just one perspective, for 3D you need 2.

Its a lot easier to do this with dual displays, as you only really need to modify the camera config in openGL, or your F/X API of choice (of course this is best done in the software itself or via the driver).

The alternating left-right eye, or polarizing, glasses are a bit harder to do properly. For those you need to synchronize to the frames coming out of the frame buffers (or else its easy to send the right image to the left eye, and vice versa...and also have all sort of sync problems). Most of these never became very popular in the PC world, most of the support for polarized glasses is found in the SGI realm.

Also, your motivation for wanting this doesn't seem to have anything to do with VR but rather security. If all you want is to prevent people from looking over your shoulder, go out and get one of those security screens for your monitor. They significantly reduce the viewing angle to the point where you can't see anything unless you are sitting directly in front of the screen.

If you're looking simply for security, I think you may not really like the price, inconvenience and eye strain that comes from VR goggles.

The point might be that you can use the goggles to project a running linux system. Yes it would be silly if you are sitting at a desk, but a decent wearable computer with goggles could be quite nice. Eye tracking for HID and what else do you need ?
Network the thing and crowds could be linked together, etc, etc.

Here's some light control grating [edmundoptics.com] material, if they don't make a panel in your size. Two of these rotated at 90 deg. to each other would leave a very narrow viewable window. Not cheap, but not VR-goggley either.

The Clemson VR lab uses (or used, at least) Linux workstations to run provide input to their VR goggles. Compatibility shouldn't be an issue, but you basically have to provide content yourself -- things won't automatically be cool. We didn't even use any kind of support in the drivers -- the goggles were two 640x480 screens, but were treated as a single 1280x480 screen. We just used OpenGL to draw two versions of our scenes from slightly different positions and presented them side-by-side so that they mapped properly onto the goggles.

Note: VR goggles are not actually cool to use. They're remarkably uncomfortable, both for your head and your eyes, and they have terrible resolution.

Since you seem to be knowledgeable about the subject:

Do you know of any VR Goggle with a wide field of view? Everything I see has at most 40 degrees field of view, which would be like looking through a tunnel. I can get a wider field of view by standing near my monitor (Which I do).

For things to be inmersive I would want the display to include my peripheral vision, even if only with very low resolution on the sides. I don't want to feel like I'm wearing swimming goggles.

My personal use for it (together with head/eye tracking) would be to write a window manager where I can hang windows all around me, and where I can switch windows by looking at them. Compiz already renders to the screen with OpenGL from intermediate buffers, extending it to a wider canvas shouldn't be that hard. It's basically being inside the spinning cube (or ring, really). But the low resolution, tunnel vision and now your comfort argument make it an unattractive proposition.

blueg3 (192743) | more than 5 years ago | (#26173807)

I'm mostly familiar with the hardware we had, which also had a narrow field of view. I don't offhand of any goggles that provide a wider field. I suspect from things that I've read and seen demo'd that there are some floating around out there.

Now, head and eye tracking we did a fair bit of. Head tracking works very well. Eye tracking, on the other hand, was quite tricky to get working properly and particularly tricky to calibrate. We had a 3D version of Asteroids where you looked at asteroids to blow them up. Using eye-tracking turns out to be difficult and headache-inducing. If I were to come up with a system similar to yours, I would make window focus based on head tracking rather than eye tracking. At the very least, you need to combine looking at a window with some non-eye action to focus it -- your eyes wander a lot, and the jitter in eye trackers doesn't help.

While I appreciate that VR stuff is both cool and fun, I seriously would not use it as a replacement for a monitor on everyday work. Visualizations that are designed to be used on a VR display, sure, but regular windows running things like Web browsers? You may very well end up half-blind with a splitting headache in a matter of hours.

Some stereo HMDs come in two flavors: one which requires driver support and is usually frame-sequential and the other that has two VGA inputs. The latter model typically costs more and doesn't need any special driver support as long as the computer can produce two outputs, usually left and right half of a wide desktop.

Only some have terrible resolution. As with many technological devices, as resolution increases, price generally does as well.

If they don't look dorky, they make you look like a self important asshole. Or you might get the best of both worlds and look like a dorky, self-important asshole.

Many's the time I wish I had a little more mobility or comfort with my computer.

Even nice headphones get uncomfortable after long periods. I can't imagine bulky goggles are terribly comfortable...

no freaking way (5, Informative)

Speare (84249) | more than 5 years ago | (#26173325)

In my last contract, I worked a VR lab with lots of toys. I have tried everything from $60 to $40,000 head mounted displays. In case you're wondering, the $60 option is an NTSC TV fed into a dimly lit monoscopic visor, while for $40,000 you get an amazing 1280x1024 digital LCD stereoscopic per eye at 90Hz. Nowhere in that range is a device that you can wear to use a GUI or a CLI interface for more than about 40 minutes. Even if your eyeball's diopter requirements are calibrated very carefully, even if your visual acuity is excellent, even if the contrast is good and the font sizes are large and beautiful, you will just not be well-served by reading text on a near-range display for more time than that.

It may be cute in the movies, but there are no options for head mounted displays that will do what you want to do, essentially live in the visor.

Agreed. VR systems have a lot of challenges to address, but the biggest one IMO is the visual part. You've tried out a much broader range of HMDs than I have, but our experiences are very similar.

I was disappointed enough that I've more or less discounted that type of interface until someone comes up with a high-resolution direct feed into the optic nerve or the brain itself. As someone who grew up reading cyberpunk fiction, I cannot stress enough how great that disappointment was.

Outside of true VR, the Cave approach seems like the best one to me, but that won't address the question in TFS because it's not portable or private.
