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."

      Actually, this has nothing to do with 3d. The only innovation here is that it is a penetrable 2d display.

    How is this different from the water screens that you see at the theme parks such as Disneyworld? (other than the fact that you do not need a lake)

  4. Not all new... by therealmoose · · Score: 4, Interesting

    This is cool, but not terribly new. At many light shows, sprayers/misters work churning out water vapor to provide something for the lasers to hit. I have witnessed several of these, and sometimes a screen is generated to facilitate the production of the light effects. This isn't really that much different, merely on a smaller scale.

      On the other manipulator, they do claim to have patented their novel fog screen dingus, so it would seem that the USPTO disagrees with you.

      Alternatively, a good demonstration of prior art would invalidate their patent.

      Honestly, the "new thing" seems to be the "non-turbulent laminar airflow" used to keep the fog confined and smooth enough to project convincing images on. Basically, it seems like the idea is to blow a smooth, flat stream of air, and then add fog or smoke to the stream. The smoother the stream, the better the image.

      Parting shot: is it a patent violation to disseminate kit ideas? I know that the patent itself needs to describe the invention pretty well, but would it be actionable to put DIY instructions on the web? Cause this is kinda neat, and it looks like it might be doable with honeycomb paper, a hair dryer and a block of dry ice.

  6. Cars and Planes? by ksplatter · · Score: 4, Interesting

    This would be pretty cool if you could add it to a car. When there is a heavy fog to drive through you could project images of the road in front of the driver.

    Fog has also been know to shut down airports for quite some time. If they could project an image of the terrian pilot would be able to take off without a hitch.

    sounds pretty amazing

  8. How cool is this?!? by Cervantes · · Score: 5, Funny

    It's about damn time... think of the applications once it gets out of alpha...

    - use it as a screen in a home theater... minimal exposed hardware, no screens to pull down or cats scratching at the pretty moving lights... woohoo! (downside: sneeze, and you'll have to pause the movie until the turbulence dies down. And Linus help you if you open the windows!)

    - If this could be scaled down, think about the niftiness of laptop screens made with this! You could even scale them to your particular situation. (on the plane in Coach? Have a nice 12" screen. Made it to the hotel in one piece? Crank it up to 12'!)

    - Use this in place of LCD screens for that fancy artwork on your walls... hmm, I wonder if you could rig up to sense movement in the fog field... nifty "Minority Report"esque GUI, here we come!

    - (submitted by co-worker who just happened to walk by) Rig one up in the ladies locker room, and project the wall about two feet from where it actually is. Hide behind fog, enjoy view. Hope they don't have a towel-snapping fight and blow away all your fog...

  12. neato, but necessary? by mugnyte · · Score: 5, Interesting

    First interpretations:

    This technology has a bit to go to achieve commodity-level feasibility. However, its very promising. I would expect to see this in clubs, concerts, and tradeshows.

    This isn't 3D. Its a flat image projected on a water-based screen.

    The drawback continues to be the placement of a projection device and its medium (if not a wall). Here, you have a fog wall and a projection TV device. Until those two converge, we'll all still hope for those "Help Me Obi-Wan" shots.

    Shouldn't there be a way to build a floating image from the interference of two separate light beams? Wherever the beams intersect would be brighter/changed. Hmm.. Maybe only good for vector displays.

  13. Indiana Jones at Disneyland by stefanlasiewski · · Score: 4, Interesting

    There is a ride called "Indiana Jones" at Disneyland. One of the special effects used in the ride is similar to the water screens and to this WAVE.

    In the effect, a machine sprays some fog, and a projector projects an image of "rats crawling up some vines" onto the fog, and your vehicle travels through the projection, which makes it seem like your traveling through a bunch of "rats crawling up some vines".

    It's pretty cool, but only when the air is still enough for you to see the rats. People with rat-phobia can really freak out.

    Other times, air turbulance moves the fog around too much, so all you see is a very distorted image of the rats (Imagine watching a movie on a shredded movie screen).

    This product claims to reduce the turbulance by containing the fog inside a "laminar flow", whatever that means.
