Walk-Thru Virtual Environment

diso writes "Walking through a wall is now really possible. WAVE, a Walk-thru Virtual Environment is a novel, low-cost, and simple method for forming a superior quality physically penetrable fog display. It is a break-through technology, literally! This work has international patents pending. An early prototype was constructed with honeycomb paper as a low-cost laminar airflow generator. When the screen is formed, images can be either rear- or front-projected onto it. Despite of being a very early prototype, the experimental fog screen already proves the operating principle with excellent results."

      The problem with this idea, is that naturally-occuring fog is 3-d (the depth is roughly the same size as the height and width) This 'machine' produces fog which, ideally, is only a centimeter or two thick, and dense enough to reflect light efficently.

      With naturally occuring fog, if you had (for instance) a projector that projects an image of the road into the fog, it would be VERY unreliable as the light would reflect back well in one section, but not be reflected back in another. Yo umay think this is fine, as if no light gets reflected, you can see the road, right? Wrong. It is like watching an old 8mm being projected onto CmdrTaco's fat back, it would be distorted in most areas, and you can't see the part of the screen that shines outside his love handles. With projecting onto natural fog, it's VERY inconsitent. - Try this with a 'Batman' template and a good Maglite flashlight one night in the bathroom (with a hot shower running)

      The other point I wanted to mention, is that the reason airports get shut down and you have a problem is because of the 'reflecting' nature of fog. If, for some miraculous reason, you were to project an image onto the road (or FROM the road in an airplane's case), and it was visible to the driver/pilot, the vehicle you were controling would have to shut ALL forward-pointing lights off, otherwise, the projected image won't show up. If you want proof, then make your own 'walk-thru wall' and shine a bright light at the image you are viewing. What do you see? NOTHING. (except for fog)

    As we all know, a neccesary component of any future society (Star Trek aside) is really crappy display technologies which are "cooler" than they are functional. If it's vertical and transparent, who needs legibility? If they can make this shizit three-dimensional by sacrificing some more resolution and possibly some framerate, we'll have a definite winner.

    Mixed reality and immersive projection technology can use CAVE-like virtual rooms with fog walls, making them effectively "virtual virtual rooms".

    The preceding sentence is effectively unintelligible without immersive technical jargon technology.

    What the fsck is *mixed reality*!? Immersive projection technology is obviously cooked up because *fog screen* is just too mundane. *CAVE-like virual rooms with fog walls*!?! And the topper: *effectively virtual virtual rooms*? Both sides cancel leaving an effective semantic value of null.

    Basically, once you get to the point of being able to project light to any point within the fog ... heck, you've got yourself a working hologram, no? So screw the fog ...

    And, uhm, have you noticed, when driving in fog, that you can't see very far into it? In order to get good image quality on it, it'd have to be pretty thick ... your 3d image would be lost, with you looking for taillights.

  80. Re:hmm how about encasing the thing in plexi glass by vidarh · · Score: 2
    And exactly how would it be different to project on fog trapped between plexiglass and projecting on other types of screens?

    It would stick out just as much as with any other projection technology - the problem with projection is being able to project a clear enough image with high light intensity without ending with a ridiculously deep screen. That problem is exactly the same whether you project on fog, a piece of cloth, or your ass...

  81. they already do it in Italy in an amusement park by kipple · · Score: 2

    it's called Gardaland. They project a story on a 'wall' made by water shot at high-pressure all around. Nothing much.. but the fog was a good idea. I wonder if they can keep the fog in a glass sphere and then use lasers to make certain point inside the sphere (in a 3d plan) to be colored, thus obtaining a hologram.
    Maybe fog can be substituted by a more transparent gas, just to improve definition.

    oh well, just ideas.
