Gives Kinect for Windows developers easy access to the capabilities offered by the Microsoft Kinect device. This SDK is designed for non-commercial purposes only; a commercial version will be available in early 2012.
It includes drivers, rich APIs for raw sensor streams and human motion tracking, installation documents, and resource materials. It provides Kinect capabilities to developers who build applications with C++, C#, or Visual Basic by using Microsoft Visual Studio 2010.
