Next Generation of Holographic Images 183

suman28 writes "Imagine being able to view an image from all sides and have it interact with you. Scenes or images pop-out at you and change on the fly and are viewable in full color. Best of all, you don't need head-gear or any wearable device to make this possible. They are generated by a computer with two cameras that track your eye movement and there is a transparent LCD screen between you and the display that makes the pictures come alive. Though it may be a while before this becomes part of our daily lives, it is interesting to see what the kind of research being done on this. "

      Even though everything is "behind glass", you are still seeing 3D. Afterall, the glass is transparent, it's not like the glass is "producing" the images...

      Besides, driving down the street, you will want some *depth* perception. What's funky are those prescription windshields... Try being a passenger in one those cars. You almost need to be stoned/drunk to survive that without a migrain.
    • You should try driving with one eye closes some time to remove your depth perception. See how well you can avoid those giant orange pyramids in the distance. You certainly need 3d for driving.
    • Not to offend our one-eyed readers, but some of us have this thing called depth perception that does, in fact, make driving a 3d experience.

      People with only one eye still have depth perception - they just don't posess stereo depth perception.

      There are many different cues that contribute to our perception of depth: stereo, perspective, parallax, overlapping objects, shading and shadows and changes in accommodation and convergence of the eyes.

      Those with one eye lack stereo (the strongest cue), but still have a decent amount of depth perception for surviving in the real world. It is only when attempting to use devices that rely soley on stereo to generate a pseudo-3D image that they have problems.

    • I was tihnking the same thing but for regular monitors. They already sell those fruity 3D lcd shutter glasses anyways. So if a monitor refreshes at 85 to 120 Hz, you could theoretically show 2 people different screens at 42.5 to 60 Hz by showing each an interleaved screen that was synced to their glasses. So if you could get Quake, UT, etc... to work with a simpler control device, you could have two or more people play with the same system.

      I don't think the computing power is there though to accomadate running the same program twice on the same computer, although really you are just performing the tasks that the programmed AI would do for a character in the game, so maybe giving more manual control isn't a big deal.

  • Traditional holograms are made from two beams of monochromatic light.

    Using any old He-Ne laser you may have lying around the house, provide the light source.

    The beam from the laser is divided into two paths. One beam is used to illuminate the object; the other is just a reference beam; you could even shine them while watching Baywatch or something as long as you can keep them fairly steady during the bouncing juggly scenes.

    Also, try to find something in the kitchen or basement that has eight segments coated with a high-quality aluminum to provide for reflectivity in steps from 10% to 80% at 45 incidence (use a ruler or tape measure for quick measurements).

    Oh, one more thing -- the laser should be on for about a half-hour to allow it to stabilize. If it's not warmed up enough after that time and doesn't seem to be very bright at all, peek into where the light comes out while it's on to check for any dust specs that may be impacting the light's exit from the device.

    Bottom line -- (cos^2)(theta) dependencies rock!
    • peek into where the light comes out while it's on...

      ...and never see out of that eye again!

Not only will gigantahumongous hard drives be required to hold this data, but extremely large memories, fast processors, and fast video systems will be needed. For a few years now computers have been quite fast enough. The web only needed a certain amount of horsepower, and as much as Microsoft has tried, there really a limit to how bloated and slow IE can be made. The newer chips eat IE for lunch. That's bad news for chipmakers, because it's hard to sell faster computers to customers who are satisfied.

    That new visual, physical interfaces need to be devloped inorder for Games to really become interesting.

    For years now we have been playing games in 2D,(ok sometimes shitty 3D) and a controller with several buttons.

    All that has improved, in all these years is graphics quality, and bigger, more-in-depth games. But we continue to use the same interface to the game, therefore all games can be summed into, push this button to do x, push this button to do Y, or combinations etc.. Games have become boring to me.

    But to get real innovation in games, we need interfaces such as this hologram tech, or forced feedback suits etc.

    When I can manipualte a 3D object(like an apple)with my hands and fingers, and I can feel it, spin it etc. That is when games can become really interesting as escapes from reality.

    I know there are people working on these things, and I know that there are quite a few difficulties but, I think only then will Gaming come into its own, ESPECIALly INTERACTIVE GAMING.

    Since home game systems have caught up with arcade hardware at low cost, there isn't a sufficient technology advantage to keep arcade gaming advantageous and afloat.

    Serious holographic displays on arcade machines would be fantastic, and home consoles wouldn't be able to touch it for many years since TV/monitor standards are so slow and entrenched.

    Note: please allow 3+ years for development and adoption, and keep your fingers crossed that arcades still exist then.

    The cameras can easily isolate the viewer's bright pupils, enabling them to track the eyes and adjust the location of the shifting stripes so that they always block the image in a way that sustains the stereoscopic effect.

    Sounds wonderful, but one limitation that jumps immediately to mind is that the 3d effect is limited to a single viewer. I was reminded of the scene in "Minority Report" which shows Tom Cruise watching 3d video of his deceased wife, and then the eerie image distorion of the wife as the camera shifts from Cruise's POV to circle behind the projection.

    • Sounds wonderful, but one limitation that jumps immediately to mind is that the 3d effect is limited to a single viewer.

      Yes, but is this really that much of a limitation? Obviously for most computer work (or play) there is only one user so then it does not matter. In fact, it could even be an advantage, since the guy next to you on the airplane would not realize that you are watching pr0...er, see your sensitive business documents. For other uses, say family video night, you would have to replace one screen with several of these devices. That would not have to be very expensive, especially not compared to getting one of those enormous TVs that everybody has these days.

    • one limitation that jumps immediately to mind is that the 3d effect is limited to a single viewer

      That's only the NYU system and the article says later that they're working on that. The MIT true-holograph system can produce the 3D images for multiple viewers, but is limited by the massive quantities of processing power needed. Meanwhile the NYU system runs on a pc but only gives the effect to one person, though:

      "The group is also working on a system that would simultaneously provide 3-D views to multiple observers, such as a team of surgeons debating the best approach to a difficult procedure or a group of video game players competing on a shared monitor"

    Holograms do more than simply stereoscopic 3D. A hologram encodes the entire wavefront of the image, not just two positions like 3d goggles or other cheesy steroscopic devices.

    This differences is substantial: the amount of information presented to the eye is vastly larger than simple stereoscopic methods. In a simple stereoscopic image, all objects and surfaces appear to be in the same focus plane. Holographic images essentially gain a 3rd axis of resolution by adding a very large number of focus points in 3 space.

    This also allows for true perspective wherein different viewpoints provide different information. You can 'look behind' objects in a hologram, which you cannot do with steroscopic tricks.

    Thus, true holograms provide a qualitativly better experience over existing 3d methods.

      How is the main technique described in the article not a hologram? It specifically involves shining a split laser through a material that contains an interference pattern. The only difference is the interference pattern is created by calculated soundwaves passing through a stack of tellurium-oxide crystals, instead of using film.

  • Just great, bad enough I get pop ups in my browser, the possibility of popup spam on the Wintel box at work, but now I may have to put up with pop up sharks from Jaws XI like poor Marty McFly did in Back to the Future.

    Seriously though, while this is fairly cool, it could also lead to some extremely annoying street advertisements on the sides of buildings. Its bad enough to have billboards everywhere, but now ones which can actively annoy you in 3D? UGH!

    That and maybe all bartenders being replaced by the Max Headroom version of Ronald Reagan.
  • I know I am super late on this, but what the hell...

    This is cool technology, and does have obvious practical uses as outlined in the article. But it will never replace the potentials offered by HMDs (Head Mounted Displays).

    HMDs offer the the one thing you can't get from a 3rd person perspective - immersion. Unfortunately, HMDs still have some serious drawbacks, the greatest of which is the fixed focus. Some HMDs are supposedly focused at "infinity", but they are still fixed focus in that there is no way to create the different levels of focus that the real world offers the eyes - everything is at the same distance. Thus, your eyes do not change focus as they do in the real world, which leads to eye strain. Once this issue is overcome, and issues relating to FOV (field of view) vs. resolution (namely you can't get a big FOV with high resolution yet for any reasonable amount of money - it is always a trade off) are surmounted, the ability to work and play in simulated VEs (virtuals environments) for long periods of time will become a reality.

    That is what I am waiting for...
