Microsoft have had runaway success with their Kinect for Xbox and within days of launch third-party drivers were developed which enabled the technology to work on Windows. This even surprised Microsoft and in a strange, yet great move, they've released the SDK. With the SDK release comes some very cool things like compatibility with Microsoft's WorldWide Telescope.
The above video shows the program having hand gestures to zoom out of our solar system, swing the cameras view around and it seems quite natural. The demonstration is awesome and makes me want to use Kinect on PC with WorldWide Telescope. The program is cool enough as it is, but hand gestures? Nice one, Microsoft.
