We introduce a simple technique that enables robust multi-touch sensing at a minimum of engineering effort and expense. It relies on frustrated total internal reflection (FTIR), a technique familiar to the biometrics community where it is used for fingerprint image acquisition. It acquires true touch information at high spatial and temporal resolutions, and is scalable to very large installations.

And about "Apple's new monitor", that's just speculation.

While touch sensing is commonplace for single points of contact, multi-touch sensing enables a user to interact with a system with more than one finger at a time, as in chording and bi-manual operations. Such sensing devices are inherently also able to accommodate multiple users simultaneously, which is especially useful for larger interaction scenarios such as interactive walls and tabletops.
Since developing the FTIR (frustrated total internal reflection) sensing technique, we've been experimenting with a wide variety of application scenarios and interaction modalities that utilize multi-touch input information. These go far beyond the typical "poking" actions you get with your usual touchscreen, or the gross gesturing found in video-based interactive interfaces. It is a rich area for research, and we are extremely excited by its potential for advances in efficiency, usability, and intuitiveness. It's also just so much fun!
Our approach is force-sensing, and provides unprecedented resolution and scalability, allowing us to create sophisticated multi-point widgets for applications large enough to accomodate both hands and multiple users.
Yes, yes I'm back.
Somewhat.

only thing that boggles me is who wrote all those programs to do all that stuff? To me it just seems like animation mixed with good timing. I can see it might be functional since it's just a touch screen that can sense more then one point.

The apps are already there, they just added an interface to allow the screen to communicate with the program.
Sort of like writing drivers for a certain joystick to function with a flight-sim, or similar.
The point being that although the technology is nice.. its not *THAT* good. The applications shown in the video make it seem like an utterly new technology, but in reality the only change is that this is a pressure sensitive and multi touch screen.. rather than a normal touch screen.
The applications involved will make it special. They exist already? Mmm.. I dont know how true that statement is..

Of course, I was more talking about the image manipulation and design type applications seen. From what I know (and of course I could be very wrong) nothing like that is currently avalible and I really feel it would be just as useful an application using only a mouse.
Are just two examples of attempted "3d" desktop environments which seemed to be exactly what was going on in the show reel.. Either way, the technology alone would be good, but it needs an entire OS (or shell) to support it.. this wont be comming out anytime sure thats for sure, but it would be great to see MACOSX taking this on in the future.
It would be perfect for education in a class room by letting kids get hands on with things without actually touching them. Maybe for models of forts they could explore or attack.
I think this is sick. I'd much rather have say a big (but really flat and light) monitor that i can sit on my lap/use anywhere in my house and play games or browse the internet or whatever.
Kinda like the star trek touch system computing they have. Fuckin sick. So much simpiler and neat.
Yes, Im obsessed with some of the technology they have on star trek...the data pads and tricorders are fuckin badass, no matter what u think of star trek

Fuck you guys....Star Trek is the shit Only Star Trek: The Next Generation and Star Trek: Voyager tho - Deep space nine and enterprise fuckin suck...the original star trek sucks to, never liked Kirk
Badass shows...smoke a big spliff and trip out to quantum mechanics, pulsar shit... wicked.
