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 once worked in an acoustics lab where people detected tapping and dragging motion using a flat surface (regular table) with a few cheap piezo microphones stuck on it and a computer program.

It's crazy that modern touchscreens use something as complicated, unreliable and expensive as capacitive sensing, when so many simpler approaches exist...
