Microsoft HoloDesk: when you need to juggle something that isn't there (video)

If you'd thought that OmniTouch and PocketTouch were the end of Microsoft Research's natural user interface projects, think again. It's now released a video of the HoloDesk, a tool that lets you manipulate virtual 3D objects with your bare hands. Looking through a transparent display, the objects react nearly instantly, rolling from a sheet of real paper into a real cup and falling into shadow if you block the virtual light-source. The Cambridge lab that developed the tool sees uses in remote working, collaboration or device prototyping. If you hadn't guessed, there's a hacked Kinect at the heart of HoloDesk's DNA, which makes us wonder how long it'll be before we can use it to play Halo.
