Straight out of Minority Report. I'm sure Nintendo would love to come out w/ something like this. http://mrl.nyu.edu/~jhan/ftirtouch/
Cripes. I don't have Quicktime installed, so when I went to that page QTTASK.EXE was not only launched as a TSR without prompting me, but it was even added to my autorun list in the registry. And I've got my security options set moderately high, too. Might as well be a freaking virus. Anyway, that's a pretty cool video (I think it was posted here a couple weeks ago). I can't wait till we see tablet PCs as small as that thing from Microsoft we were talking about but with touchscreens like this. I'm sure it could have some great uses for gaming, but just for general interaction an all sorts of programs, it'll be pretty great. I'd love to see what Jeff Minter would do with a system having this kind of input. Some of the sequences in that video make me think how cool some sort of Colourspace or Trip-a-Tron thing with actual game elements added (which is more or less what Unity would have been) would be. Some super-abstract music-generated fractal-geometry adventure-happening. God I could love a game like that. ...word is bondage...
Here is a different thread that also talks about it: http://assemblergames.com/forums/showthread.php?t=8701
Neat. Not revolutionary (multi-point touch tech has been arround for a while, but was pulled off in a different way), but fun stuff non the less. Speaking of experimental tech, what ever happened with that one that was posted a year or so ago where a room was mapped and a 3d toy car was imposed over it on a screen, but with the ability to understand how it should interact with the environment (Not sure how to properly explain it)?
