Google purposefully took multitouch out of Android on Apple's request.
Um...Apple can %#!@ off. Can't put it any other way really. Touching something at at the same time, ooooh, yeah Linux has had it for a long time, Youtube MPX sometime, it's been all over the place, and it's nothing "special", it's just that it's finally being used in programs. Screw Apple and screw software patents, which this probably has something to do with.
In multi-point touch, each touch is treated as a separate pointer. That's what you see in that video. Multi-touch treats separate touches together as gestures. You know how on a MacBook, you can pinch your fingers together/apart to zoom, running two-fingers across the pad will scroll, three will navigate, etc. With multi-point touch, swiping two fingers down would move two cursors down on the screen, not scroll.
Multi-point touch is undoubtedly awesome, but it's not multi-touch.
I thought I remembered that vid having multi-touch on the map, but it doesn't.
I was also thinking about the Jefferson Han stuff - back in 2006.
Of course that is just an SDK which looks like it actually runs on Windows (Perceptive Pixel) - but I wouldn't be 100% sure.
Half of the earlier FTIR was on Linux, while the other half was done in Flash IIRC.
I also think the progression from resizing a window (as shown in the video) is not such a big leap away from "guestures".
I think that a patent for multi-touch on a specific device (which I'm thinking Apple/MS would do) is totally idiotic.
Multi touch on a wall, is the same as multi-touch on a floor, is the same as multi-touch in your pocket (ignoring the fact you'd have to group the 'multi-touch'es in different sized circles in each).
