Making A Video Screen Out Of Thin Air
from the drive-in-movies... dept
AMetamorphosis submitted the following story without a link, forcing me to hunt it down myself. Just a reminder: if you're going to submit a story, please include a link and why you think it's interesting - and not just the text of the article itself. Anyway, Reuters has written up a story about various efforts to create walk-through displays: video screens without the screen. A few weeks back we wrote about a company called HoloTouch that was working on a similar system that also allowed for input via the air. The Reuters article, though, focuses on two other options. One is basically a fog machine that creates a temporary screen out of water vapor. The other sounds like an attempt to create a holographic projection system (the guy even says he was inspired by the holographic display from the movie Star Wars). These all sound pretty cool in terms of getting attention - but it remains to be seen how practical they really are.

Making A Video Screen Out Of Thin Air
I was reading a book a couple months ago called something like "Visual Special Effects Toolkit in C++." In the book (second chapter, I think), an invention was mentioned, although I can't quite recall the name. What the invention does is split a normal screen (such as a TV) and project it into a room. Apparantly, this invention's most famous use is at some theme park here in the U.S. that displays a spinning superman logo. I have actually seen this invention used before in an art gallery. A TV was suspended above a diorama and a angled pane of glass was below it. 3D "people" actually moved around in the diorama scene. I thought this invention would make movies a whole lot cooler. Anyway, sorry I had so little details, but I hope somebody out there knows what I'm talking about.
