Microsoft "Microsoft and Perceptive Pixel Inc. (PPI) today announced that they have entered into a definitive agreement under which Microsoft will acquire PPI, a recognized leader in research, development and production of large-scale, multi-touch display solutions." Yes, Jeff Han is now a Microsoft employee. This demo still amazes me - from 2006. Before the iPhone. Before Android. Before the iPad. Remember that the next time you wind up in a discussion about who supposedly invented what.

I'm not convinced that a microphoned approach would be any more reliable than capacitive sensing. In fact I'd wager it would be far less reliable as it would be subject to outside interference. It's one thing having such a technique work in lab conditions, but when you're at a noisy train station and the phone is in your pocket or trying to detect multi-touch gestures under such environments. Certainly in the for former scenario, you could run the risk of triggering all sorts of false positives. Sure, with enough code you could account for most scenarios, but then you'd create something more complex then detecting the variable voltage change from a persons fingers.
