3D Display a Little Bit Closer to Reality

arielsebbag writes "According to CNET, Several high-tech companies including Sony and Sanyo have officially unveiled a consortium to create technical and safety standards for bringing three-dimensional displays to desktops, laptops and cell phones. They are probably focusing their efforts on the technology developed by Sharp. It looks like they are actually good to go and hopefully the 3D display will hit the market by 2004."

      These 3-d displays that they are talking about send two different pictures in different directions. In that ways, you get an illusion of parallax so you see depth.

      On a regular moniter, things may be rendered in 3-d, but they are displayed in a flat method. This can be approximated in the real world by closing one eye. With these screens, you get the asme 3-d illusion that you get in a "magic eye", where your brain interprets slight differences in pictures between you two eyes as depth.

      The problems mentioned, such as the fact that it does not know where your eyes are to send the right images to the right places, are being worked on, but eye tracking makes the system much more complicated.

      There are other, more fundemental problems with screens. Among them are that the focus plain is still on the screen, eevn while the sterio says that the image is somewhere else. This can give people headaches.

      No. That was precisely my point. A hologram is a real effect to the point that it has focal planes. In an analog hologram, every piece of information about a light wave, including its direcion and intensity, is saved in a diffraction pattern, that can be read by shining the reference beam again. In a holographic video system, something is causing the exact same diffraction patterns that the holographic plate would have stored.

      The beam is never focused anywhere. It is brought back when the hologram is viewed. The loss of focus planes would come from projecting a focused image on a screen, the first place that happens is your eye. You can focus on the front of a hologram, and the back is out of focus, or visa versa. At my lab they have printed some holograms and messed up the focal planes so they just looked wrong.

      There are two components to how people use the focus cue for depth perception. There is the blur gradient, that is how things in front of and behind your point of focus get blurier. There is also your eye muscles physical accommodation to this depth. Research seems to indicate that the blur gradient is not as important as the eye's accomodative depth. The depth of focus is a really hard thing to simulate on a display. You can try to use a measure of gaze direction, but to stop people from getting uncomfortable the lag needs to be reduced to almost zero. So you effectively need many depth planes you can project onto.

      As for holographic displays, one of the problems with them, or any volumetric display, is that there is no occlusion in the scene. This really limits the quality and usefulness of this method.

And selling them in more volume than anyone else is likely to be at the time, because of their access to all Mac customers.

    And Apple is well positioned for the move on the software side too. They have already re-implemented their entire windowing system in OpenGL. It would be relatively trivial to add 3D window positioning and widgets. (And damn cool in some ways too, there will certainly be some useless eye candy, but some simple obvious things like being able to look behind a window just by moving your head a bit, would by really cool imho).
