Walk-thru Fog Screen

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.

Sounds like SeqQuest...

Sounds like the hologram they had in SeaQuest DSV. Not that I ever watched that program of course... ;)

Dupe

This is a dupe from a while back (almost a year ago)... slashdot

Repeat

We already saw this last year.

Applications
The fog screen enables many novel applications indoors. Interesting applications include walk-thru advertisements on shops or malls, or a walk-thru screen in world-class museums, corporate showrooms, trade fairs, theme parks, special events, spas, theatres, science centers, lobbies, etc. We can extend the technology to limited outdoor usage. We will also present some intriguing new concepts later.

The fog screen is silent and non-breakable, which enables safe gaming, exercise or training, and non-supervised public presentations. It also enables the audience to enter and exit rapidly through the walls into, e.g., virtual environments, which may be even sequential. Mixed reality and immersive projection technology could use CAVE-like virtual rooms with fog walls, making them effectively "virtual virtual rooms".

Just like Seaquest

... remember that? They projected a hologram on what look like a stream of vapor from the celing - very clever, even if looks a bit crappy *G*
