Walk-thru Fog Screen

Posted by CowboyNeal on from the you're-soaking-in-it dept.

fluor2 writes "Ever wanted a screen floating in air? Two scientists, Ismo Rakkolainen and Karri Palovuori, both from Tampere University of Technology, Finland have come up with an idea. It is called the Walk-thru Fog Screen. The fog screen, consisting of 'fog' that is blown down from top, and the protective laminar airflow creates a thin and crisp surface, pretty undisturbed by the air in the rest of the room, making it ideal for projector usage. People can walk right through this screen of fog. Their next idea is to use the fog as a touch-screen, making it even more accessible." For a screen one can walk through, the image quality is better than I'd have thought.

    I am not really sure what display use it has in the "real world" but it would make a great cinematic effect.

    Also you could scare folks in amusement park rides making them think they are about to crash into stuff.

    You could also hide behind it and spy on people maybe...

    Who knows...

      In the real world, fog screens tend to make terrible pileups on the highways where the crashes aren't so pretend.

      As far as amusement parks, good luck trying to keep a laminar airflow while a high velocity vehicle whizes by. And forget outdoors, the breeze would carry your image away, that's if you could even see it in the sunlight. Probably more useful in a haunted house ride...life-like ghosts, and cool the airflow and you also get the chill down the back of your neck too.

    This isn't going to be used in business meetings, where projection screens are available anyway. I guess smoke-screens will be used as advertising space: One could use them much closer to or in the way of the customer flow at trade shows, without risking damage to equipment or consumer. For that purpose, a little image unstability may even prove useful as eye-catcher.
