For those of you who have been with us for a while, you probably remember that Matt, our oldest contributor here at [GAS], has blogged extensively about multi-touch display technologies. I'm sure most of you have already read both of his articles, but if you didn't, go ahead and take a look at them (1, 2), they're very interesting. Unsurprisingly, the technology that was featured in one of these posts is really getting noticed by the world, and Jeff Han, the researcher who invented it, has started a company named "Perceptive Pixel" to pursue its development. Here is a brand new video presenting the company and its technology.







Matt adds: As you can see, this video is an excellent mix of very shiny eye-candy and real-world applications that seriously benefit from the use of a multi-touch interface. It goes way beyond Jeff Han's TED demo in showing the technology's usefulness in collaborative applications on large-format displays.



The news that Han is forming a startup company is very encouraging. One of the things that's been quite worrisome since the iPhone announcement was that Apple would claim a patent on the concept of "multi-touch". Fortunately, the fact that Perceptive Pixel came into existence is a good sign that Apple doesn't own every right on this new and revolutionary idea.
