Projected UI: a sixth sense?

Pattie Maes speaking at TED about some emerging UI tech that looks freaky cool.

Here's the image that made the audience burst into applause:

Yeah, way cool.

Full integration with the products shown in the demo is a pretty big question mark. You wonder if the tech could display its information from scanning existing bar codes, or if they would need some other standard to hook into - but still.

Wild.
