Yes, it’s official. Microsoft will be releasing the Kinect for Windows SDK soon, after a long rumour which started shortly after the Kinect Hack frenzy. According to Microsoft, “It will be available this spring as a free download, and will give academic researchers and enthusiast access to key pieces of the Kinect system-such as the audio technology, system application programming interfaces and direct control of the Kinect sensor itself.” Commercial licensing details will be made available at some point thereafter.
