If you are following my blog you'll notice that I really like Microsoft's XBOX division. In my opinion they are completely different to almost everything else at Microsoft.
And the XBOX division really performs. One of their greatest inventions was Kinect. A consumer camera system that can can track objects (and human skelettons) accurately in 3D space.
At the end your whole body becomes the game controller. Great idea.
The interesting thing now is that Kinect is coming to Windows boxes. My compliments. Great move Microsoft! It has been a while that Microsoft was seen as cool or innovative. But there are some small signs that this might change in the long run. Kinect for Windows is one of those signs.
