3-D Monitor From Deep Video Imaging 202

Posted by timothy from the that's-U.S.-dollars dept.
Silver A writes: "Deep Video Imaging Ltd. has available monitors with real, physical depth, and touchscreen capability. Unfortunately, it's only 800 x 600 x 2 so far. The base model is only $8765.00 for US and Canadian customers. This looks really cool, but I'd like to know if they plan to go to more than 2 planes, and if they support X." Or, on the other hand, if X will support them. These may have limited utility as is, but undeniably cool.

  • This seems cool, but there have got to be better ways to do 3D.

    Take the IMAX thing a bit further. Instead of projectiong two images with different polarizations, project two images directly onto your retinas. This would give true 3D, and it seems easier than their method.

    Probably be hell to program graphics for.
  • Since LCDs absorb light (rather than emit light) it is impossible to have a lit pixel behind a black area. This rules out using stacked LCDs.

  • I hit the link off Post #42, which seems to be the first in this story

    A quick look at the posters BIO [slashdot.org] shows hew posted 3 similar comments within 10 minutes of eachother into different stories

    since the script or whatever on the linked site causes a direct post back to the originating story, I figure this is the guy

    dunno what to do about it. I COULD BE WRONG - PLEASE DONT WITCHUNT. But it seems likely?
  • First of all, I'm really suprised by the number of people that click on my link and that use Win32 plateforms. Is it because most readers of Slashdot are Windows users or because Windows users are prone to click where somebody says they should not.
    Please stop to click on "retry".
    Sorry for the noise on this forum.
    I demonstrate this bug in a none agressive way, correct your sites guys, some will not !
    Click on "more" if you want more explanations on the bug, it's safe.
  • Then again, we should thank him/her/it for their hidden warning:

  • A pair of lasers hitting the back of my retinas are cool, relatively cheap, and portable.

    Stacks of LCDs are lame, really expensive, and immovable.

  • I'm curious if . . . it would be possible to do . . . with video the same thing that stereo speakers have done for sound.

    The two reasons why you can use two speakers to simulate sound from points other than the speakers are
    1) A speaker in each ear, so you can manipulate the data going to each ear and
    2) The sound moves, and by exploiting the delay involved in the sound going from the speaker to your ear, you can create these effects.

    You can do the same with displays by:
    1) Having a display for each eye (which is currently the best bid on stereo vision) through head displays, or other eye type filters (LCD shutters, polarized lenses, etc)
    2) Moving the display or display surface. If you move an LCD display in and out then you can simulate having infinite planes of display. (I've thought about this in quite a bit of depth. The main issue here is reliability of a large mechanical system including wear, sound and vibration issues)

    If you could cause the speed of light to slow down to about the speed of sound, then it is theoretically feasable that one could sit in a mirrored room and generate 3D holograms without special headgear. Einstein! Where are you!? (Said like, "Scooby-doo, where are you?")

  • Ummm... according to your logic, if something is layered it only gets a half dimension, then the screen would only be 1.5D, since it's basically layered in each dimension. It's just that two of the dimensions have high enough resolution that it is difficult (not impossible) to tell that it is not continuous. As it stands, layering, or pixellating, depending on what angle you view it from, seems to be well regarded as a full dimension. So, it seems to me that this system is in fact 3D, even though it gets very poor resolution in one dimension.

  • On Win2k (work) MSIE5.5 ALL scripting, Active X an dcookies set to PROMPT (jscript, cookies)or DISABLE (active X, any other scripting, Java)

    that page ran a REDIRECT in my browser window, sending me back to /. 's post confirmation screen w/ all the correct URLs.and I naively presumed your couldnt do a Jscript REDIRECT with my security settings

    so maybe its NOT just a slashdot bug BUT also a real bad SECURITY BREACH, MAYBE IN THE ECMA SCRIPT MODEL ?? as its in in M$ and a whole lot else

    has anyone contacted the author or poseted the explanation here yet?

    *not* redundant yet

  • Awhile back I was at a science museum (in Seattle I think) where they had a Sun workstaion that had a 3-d mouse and this pair of 3d glasses (I think they used polarized light or a LCD flashing on and off very quickly for each eye) It worked pretty well, except that it gave me a headache after awile.

  • The main problem I can see with that is that, as you add more layers, more and more light gets eaten in the sandwiched layers. You can get around that -- a bit -- with a strongeer backlight, but that still leaves you with more heat, and the layers further back will get dimmer, and dimmer and....
    In time, though, we may have a real solution to those issues. I'm sure that they're working on it.

  • Hmmm...

    But you *could* have a black pixel behind a white one. It seems to me that you could use stacked LCDs to get a 3-D effect. You just use white (clear) as the transparent color. It's no different than the real world, where opaque objects obscure our view of other things behind them.

  • One thing you can't really do with hardware layering and mixdown is provide a feeling of space - with this screen you can move your head ever so slightly and get a concept of depth, even if its only minor.

    This could have exciting implications for future GUI design, and if they perfect the manufacturing process to the point where more than 2 planes can be sandwiched (say, 32 or 64?) then we start seeing some really interesting opportunities for GUI design, not to mention the artistic value, which is often inappropriately overlooked in technology.

    Imagine a GUI that gives you a degree of depth inherently without requiring large resources - buttons could have 3d edges that were handled at the hardware level, rather than software - thus making for better resource management, and therefore leading to more efficient GUI performance. This may seem minor, and perhaps it is, but I can see how this would have potential.

    Once we get up to the 64-pixel Z-plane level of production, I can see widgets being designed that use the Z-plane to provide ancilliary info feedback to the user without requiring any more interaction on the users part than to just move their head and look closer.

    I was thinking about this similar "liveliness" aspect of GUI design the other day when playing with http://www.praystation.com/ (excellent web page) - it'd be nice if there were some way to produce a screen that could figure out what you were looking at, perhaps by bouncing something off your retina and doing geometry to get a point of what you're looking at. In the 80's, marketing devices that used lasers to see what you were looking at were used to do market research of TV commercials - it'd be nice to see something like this built into LCD screens, so we could do away with the mouse altogether.

    But the thought I had was that, with something like this, the longer you look at the control the more information it could provide you - bringing a "liveliness" aspect to the control that we don't currently have with the static 2d shapes we call user interfaces right now.

    Having a 3D screen with a 64-layer Z-plane would be another way to add 'liveliness' to an interface... you could for example build a mixing console that provides you with channel insert information, with amplituded represented in depth.

    I'd say 64-layer Z-planes would be the next major step for this company. Get things to that point, and the GUI design world starts to get *really* interesting...

  • If you want a true 3D display, IMHO the most straightforward way to go about it is to start with a lightweight, transparent, double-sided LCD panel, and add an electric motor that causes the panel to rotate about its center about 60 times per second. Presto, a cylindrical volumetric display!

    Might be kind of dangerous, though...

  • I've checked these out a little bit ... they look alot like what one of the UI developers for the original mac told wired he thought that windows would eventually go to ... (only i think that this is a little more literal "3-d" than he'd originally meant :) ... One of these would definately raise the geek-factor in a household significantly.

  • Other way around..
    It's impossible to have a black pixel behind and a lit pixel on top.
    For the techs out there, they simply use a standard (matrox?) video card set at 1600x600 - the left half of the display is underneath and the right half is on top. It makes for some <ahem> interesting mouse navigation.
    I've overheard that their intended market is embedded kiosks - like those automated movie dispenser things or the "virtual tour guide" at the tourist center.

    Essentially, if you ask a web server for a page, the server can send back a redirect, saying "actually, it's over there." Your browser then goes to the new page and asks again. Redirects are useful for a number of purposes; for example, when a web site moves a redirect can be put in to point readers to the new site transparently. (Thus, for example, some people still go to www.eklektix.com/lwn/ to read LWN and it works, even though LWN has not been there for two years).

    Yet the problem here is Slashdot itself... and nothing else... From what it seems, Slashdot figures who is posting simply by looking at the cookie.. and nothing submited from the form..

    Thus the "Security hole" page auto submits to slashdot which reads your cookie and posts a comment under your name..

  • Problem -- Pixel Aperture Ratios (Score:3)

    "I can't get to the site right now, but why couldn't the company make just layers of LCD screens?"

    I imagine this may have something to do with pixel aperture ratios. An active-matrix LCD panel isn't completely transparent--the transistors and other components take up space and occlude part of each pixel. A high-aperture LCD might have as much as 70-80% of each pixel open, but even so you'll eventually loose too much light as you stack up more and more layers.

    First of all, this should really be labelled 2.5D, not 3D, since it is layered.

    It was only a matter of time until people started coming out with displays such as this. Layering 10 transparent LCDs would be good also.

    The problems is the bandwidth needed to drive such a beast. Imagine 10 layers (not very many at all) and 1024x768x24 at 60Hz. This means you need a graphics card capable of handling over 12Gb/s of data. In comparison, my 1600x1200 monitor only needs 46Mb/s of bandwidth.

    But then, bandwidth is a widespread problem that is getting more attention than other problems. Imagine an HDTV receiver that gets 10 channels synchronized to a 10 layer monitor... 2.5D movies, anyone?

  • Can you mod down all those stupid "auto posts" without killing everyone's Karma? Pretty please?

  • You know, with all these warning replies, one really has to wonder just who is actually still clicking on that stupid link. Not much I can do, though.


    --------------------------------------------
  • You just need to move the monitor 'closer' to the bus. 16x12 requires 46Mb/s in raw form (over the cable to your dumb display) but there sure isn't that much travelling over the system bus, and there ain't that much activly being transferred internally by the video card either! So there has to be a place we could 'snip' off the video card and move outboard to the display. Say after the geometry has been calculated for the frame, it's compared to the last one and sent to the monitor as vectorized meta-data, along with the appropriate bitmaps to paint with. Monitor keeps tabs on the totality of the image in a seperate framebuffer array.

  • Well, you'd need more than 2 planes for that type of thing. Seriously I don't think it will ever get that evolved. If anything games will just be more immersive, but I don't think that any practical differences in the way you play them (ie physically moving around the monitor to look around corners in a FPS) will ever come to pass with 3d monitors. Maybe with VR units.. but not 3d monitors.
  • And remember, whenever you make an Assumption, it only makes an "ASS" out of "U" and "MPTION." Or something. Obviously there are quite a few stupid *nix users here too, and probably a lot of Windoze users who never clicked on the bad link (including me.)

    OTOH, the high Stupid-Windows-Users count here could be explained by the fact that MS employees regularly scan Slashdot for copyright violations.
  • I don't see the point of making physical 3D. Human vision is 2x2D, so instead of 640x480x500 (whatever...) = 153M/update, why not do 640x480x2 directly in the brain? With head movement detection you could even have that moving thing. And while I realize this is expensive, it might be cheaper than to stack, stack, stack the screens. -Kaatunut
  • I must admit that I didn't take the time to look through the whole website but I was just curious. I remember seeing a 3D tv screen while I was on a tour of Universtiy of Manchester, in their 3D labs a couple of years ago. Also, on the BBC, I saw an article about such devices in Japan. They work on the principle of the freznel lense I think. It basically acts as hundreds of round screens on a plane. When you look at each bead, it shows you a slightly different view of pixel than from other angles. The camera works like an insects compound eye. Not yet available but looks promising.
  • I think i was the first to accidentally hit the link. So the guy who posted it is very probably poster number 42 [slashdot.org] and my first thinking about this was in post number 213 [slashdot.org] But we've been all too busy to even call him an agrravating Frog yet (his site is in France) #8~)

    Hey, I tried out Virtual Boy! I didn't buy it, mind you, I rented it. For the first 10 minutes after I started using it I thought it was the coolest thing ever made. Then my eyes began to hurt, but for some reason I kept playing. Then I finally realized that there was something like a total of 4 games for it and they all sucked royally. I also realized that if I used it much longer my eyes would probably start bleeding or something. Anyway, once the novelty wore off it was hard not to realize that Virtual Boy was just a crappy system in many different ways. However, that does not mean this monitor concept is necessarily that bad an idea. I just hope my eyes won't start bleeding if I use it.

  • Actually, I think it is kind of fascinating. I see a number of links -- and not "hot news" links, either -- that show up on memepool and then later mysteriously appear, uncredited, on slashdot. There have been at least two (or perhaps three, depending on how you count) this week alone.

    I think we can all agree that information that is freely shared is good for everyone. It would be nice if the slashdot editors made at least a cursory effort to be aware of whether the links submitted to them are on another weblog. For the record, I personally don't think there's anything wrong with using the link, as long as appropriate credit is given.

    Also for the record, I am a contributor to memepool [memepool.com], and I have found it to take nearly no effort at all to check if leads I am given are currently appearing on another site. If we as members of the slashdot community expect the same level of responsibility from the slashdot editors, I have no doubt they will be able to rise to our expectations.

Layers of flat screen don't look like anything useful or interesting; you'd need hundreds of layers packed very close together to be even moderately useful.

    by Julius X ( 14690 ) on Friday May 19, 2000 @12:35PM (#1060566) Homepage
    I'm curious if using a display such as this, although the display only creates Two Dimensions, if it would be possible to do the same thing with video the same thing that stereo speakers have done for sound.

    With sound, you may only have two speakers(or more) speakers, but using fading effects, you can create the illusion of a sound being anywhere between or even outside the speaker radius.

    Would it be possible to do a similar effect using a 2-Dimensional display monitor? Perhaps the "front" dimension has an image(a mouse pointer for example), and while you move it to the "rear" dimension(since there are only two with this display), the front dimension "fades" the image into the rear dimension, creating the illusion that it has actually passed through space to get there, as if there really were more than two dimensions.

    Undoubtedly, to create the look of two dimensions, what the technology has required was one "transparent" display on top of another regular display, and all it would require would be a fading transparency effect to accomplish such illusions a demonstrated above.

    The possibllities here could be quite intriguing.

  • I was just thinking that for folks who are blind or otherwise visually impared could really use a monitor like this, especially if it were used in a display environment where folks who are also not so handicapped would also be able to use the same device.

    I imagine that there are some braile reading devices already, but this certainly could be used in a manner like that, allowing you to view web pages in braile and even grab images with some false relief so they can enjoy some of the benefits of the web as well. At least this is a very pratcial application for even using a two-height display.

    This could also be useful in applications where you need to have a configurable tactile display, such as the classic bridge controls found in the Star Trek TV series (post TOS). As you are pushing buttons you can change the "feel" of the user interface, and even "vibrate" the buttons to give a tactile response.

    Yeah, I think you could find some customers for something like this, even at the $8800 price tag.

  • A SMOF (Score:2)

    by swm ( 171547 )
    Anyway, I think that the true future of 3d monitors will be something like an Active Holographic Display; i.e. a monitor who's elements can emit different light patterns in different directions. For example, an LCD-type screen that had a mechanism by which one pixel could emit blue light in one direction and green in another. The same concept is what makes holograms work. Surely it couldn't be too hard to make a monitor that does this same kind of thing?

    A SMOF (Small Matter Of Fabrication)

    To make a holographic display, all you need is

    • a screen with a dot pitch smaller than the wave length of light
    • and the pixels have to emit coherent (i.e. laser) light
    • and you have to control the phase at which each pixel emits
    Yeah...that's the ticket: if you control the amplitude and phase of the light emitted at each point on a surface, then you can synthesize any image.

    Computing the required video bandwidth is left as an exercise for the reader.

  • Just attacked the comments page with textutils and got some stats about the people who clicked the link. (I'll post them in a follow-up message). Some interesting points:
    • Amongst clickers, Win2k is already as popular as WinNT.
    • Nearly all of the Windows clickers were IE users.
    • Netscape and IE users were equally likely to post more than once.
    • AC clickers use the same software as logged-in clickers.

    I'd love to know how representative the clickers are of the whole of slashdot. IIRC slashdot's Windows/Linux proportions a year ago were about the same as in these stats, so it's possible.

  • I had a professor who consulted with Nintendo on the Virtual Boy, and his opinion (though he said he'd never directly talked with anyone there about this) was that they were basically working out the kinks so that when multi-color LEDs were available, they'd be able to really quickly put together a viable 3D system. He had a whole bunch of pre-production units in his office, and we got to poke around in them quite a bit. They were pretty crappy as a platform, but mechanically/electronically they were really, really cool. Mark my words- cheap blue LEDs aren't very far away (they are in limited production already in Japan) and when their cost gets reasonable in a few years, Nintendo will come out with Son of VirtualBoy- and it'll blow us all away.

    Pretty easy to answer: The people who want/need it. Not many people have much use for someone who can dunk a basketball from the 3 point line 95% of the time either. On the other hand, the people who do (e.g. NBA teams) are willing to pay a REALLY pretty penny for the ability.

    Similarly when I'm looking for a job. Not everybody needs my skill set, but those who do are willing to pay reasonably well for it :-((But not as much as Jordan gets))-:
