3-D Monitors From Actual Depth

Klenex writes "True 3-D Visual Effects w/o the use of annoying '3-d' glasses or stereograms. Actual Depth "The Actual Depth monitor is actually two LCD displays stacked on top of each other. The LCD on top displays white transparently, so you can see through to the display beneath it, which is opaque." You need a dual head card or a 2nd video card to drive each display but this seems incredibly cool and it will work with any OS which supports dual monitors w/o any other hardware. Here's TechTV's scoop on the new technology. They even have a link to contact them about a demo in your area.

      The 3D IMAX screen preserves polarization through reflection; the images are generated by two projectors, each with a polarizing filter 90 degrees out of phase. If two stacked LCD displays are polarized 90 degrees out of phase, then the closer display will completely interfere with the farther display. Thus you will see the closer display through one eye and a blank screen through the other.

      On the topic of 3D displays, while I was at GDC I checked out a projected 3D display, just like the IMAX solution. Still expensive. They also had a shutter glasses solution.

    Traditional 3d hardware includes 3d accelerator cards, immersive-display goggles, stereoscopic LCD goggles, crystal-ball type volumetric displays, and the (theoretical) realtime hologram projector. But the problems those devices attempt to solve are almost completely distinct from what the ActualDepth display is meant for. (Well, except that a truely effective hologram projector could emulate any other display technology...)

    The point of ActualDepth is to allow your computer to present you more visual information in the same space. If you run traditional software that's not aware of the special screen layout, you can just use the multi-monitor feature of the OS's gui system (in X11 they call it Xinerama) to assign some windows to the front screen and some to the back. That way you can look at both of them at once, and for instance can read the online manual for a game at the same time you play it full screen, or operate a 3d-modeller in the classic 4-way parellel projection while a textured preview of the object sits on the back display. Anything that you'd do with dual-monitors, you can do with this, but using less physical real estate, and, more importantly, with less time to focus your vision from one to the other. Both screens are centered in your field of view at the same time, so there's no looking back and forth nessecary.

    It's likely that without modifications, your GUI interface will only allow the mouse to switch between screens by you dragging it across one edge of the screens, where it considers them seamed together. That is irritating and unintuitive, so you'd want to use one screen as more of a read-only device, showing useful data but rarely needing interaction.

    Elsewhere, someone asked if this effect can be emulated in software just by alpha-blending on image on top of another. You could try this, but it wouldn't really work. At the points where the foreground image is solid (thick black text), the background will be completely obscured. But with "actual depth" between the displays, the stereo-graphic effect of dual-eyeballs comes into play. Assuming the foreground image is mostly line-art or text and doesn't consist of large regions of solid color, then for every pixel in the background image, at least one of your eyeballs will have an unobstructed line of sight to it. You remain aware of the contents of both displays with no additional perceptual effort.

    The device I tested had a touch screen attached in front, and the window-manager (well, Microsoft Windows(tm)) was configured so that a single-click on a titlebar would shift a window 1024 pixels left or right, effectively toggling it between the front and back displays.

    To begin to recoup some of the enormous pricetag for ActualDepth hardware, though, you'd need to run software that's aware of the display's special characteristics. (The code doesn't need to link any special drivers or new APIs, but it does need to be aware that graphics drawn at (X-1024,Y) will appear floating over (X,Y)).

    Essentially what the application should do is allocate one display for data, and one for meta-data. That is, if you're word-processing a document, the back display should always give a WYSIWYG preview of the output, and the front display should present all the filenames, font names, editing markup (including those automatically-generated spellchecker warning scribbles), section breaks, margin, column boundaries, etc.

    I'd really like to see what user-interface innovations would pop out if the programming public got to play with these monitors for a while, but at the current price, that's just not going to happen.

      The polarized or color-based "passive" 3D glasses are not considered to be good enough for people who wish to do work in 3D.
      Here we go:

      - 3D goggles are only usable by one person at a time. To have multiple people view the same image at the same time you need multiple sets of goggles and multiple computers or one *really fast* computer.

      - You need some type of head-tracking mechanism to track where the user is looking. This is not trivial and introduces some annoying lag into the display

      - Goggles tend to give people headaches after only minutes of use. Some people get nauseous. This is due to the following reasons.

      - The lag in the update of the display introduces some temporal discrepancies that confuses your brain.

      - The images are all *in focus* regardless of the depth. This is not true in real life. Your depth of focus is not infinite. Notice if you stare at an object close to you, the objects far from you will be blurry. When you use 3D goggles your eyes expect objects at different depths to be at different "focal planes". Instead they are all imaged onto a single plane.

      - In a real 3D world your eyes also adjust "in and out" (cross-eyed vs. wall-eyed) to assure that both eyes are "pointing" at the same depth. Since goggles produce an image on a single plane this confuses the eyes when viewing images at different depths.

      - The update rate on goggles is typically less than the minimum of 60Hz we are used to seeing on modern monitors.

    There are several downsides to this technology:

    - It only looks 3D if you are looking at it straight on and standing a certain distance from the display. This makes it difficult for several people to look at at a time.

    - In the case of this display you need a video card that has a dual monitor output and special software to take advantage of the display.
