Jefferson Han's Demonstration of Pressure Sensitive Multitouch

In October of 2008 Jefferson Han (who presented the seminal demonstration of multitouch at TED 2006) and Philip Davidson of Perceptive Pixel, demonstrated some pretty impressive 2D object manipulation on a multitouch surface that can detect pressure.

In this video, presented at the ACM Symposium on User Interface Software and Technology 2008 (UIST 2008), Han (or is it Philip?) shows how pressure can be combined to add a third dimension to multitouch manipulation.

What is really cool about the video demo is not that the multitouch surface can register pressure, but the way in which pressure is used to extend gestures while arranging objects on the screen. The only vendor I know of that offers multitouch with varying pressure sensitivity is Stantum which I wrote about back in February.
