Multi-touch interfaces are so hot right now. While portable touch screens are being used everywhere from Windows Mobile phones to the Nintendo DS, not much has been done to take them into the home. Also, the fact that traditional touchscreens can only measure a single simultaneous click, while not too much of a limitation up to now, does restrict certain operations and more complex interactions.

Cue Jeff Han’s multitouch system that I blogged about a while ago. You can now watch a very convincing video of Jeff demonstrating the device. The talk was part of TED Talks, and features a extremely excited Han running through a number of applications for the interface, including NASA World Wind, a lava lamp simulation and something that looks exactly like Takeo Igarashi‘s “As-Rigid-As-Possible Curve Editing”.

Other TED talkers include Nicholas Negroponte, and Al Gore talking about Manbearpig.
