to all (I'm the author of http://www.youtube.com/watch?v=WNTsIut1h98): this is extremely simple and common knowledge, Engadget simply failed in posting that as some kind of revelation. There are even scientific papers on this topic (including some more advanced techniques for recognizing this kind of gesture). In short: it is not comfortable to use this technique for pinch to zoom (is someone reaaally wants to try this, PM me), as the problem is that we have two moving points. However, if we think about using that for one fixed point and one moving point, the usecase can be interesting. Think about this: Where the big circle is an analog stick and buttons are.. well buttons If the pseudo-multitouch it is easy to be able to control the analog stick and SIMULTANEOUSLY discover press of the button. Which would be nice control in the games.
