Microsoft has announced that it will release a non-commercial SDK for Kinect later this spring.

SDK means ‘software development kit’, which will allow academics and “enthusiast communities” to do cool new things with the 360 motion camera. It gives access to “deep Kinect system capabilities”; including audio, system APIs, and direct control of the sensor.

This announcement of the Microsoft Kinect for Windows SDK reflects Microsoft’s desire to unleash the magic of the NUI technology to a broader set of academic researchers and the enthusiasts by empowering them with the tools to create exciting applications with the use of Kinect technology.

Of course, many cool things have already been done without the ‘official’ aid of the SDK.

A commercial version of the SDK, allowing developers to create Kinect-based apps and games for profit, will be released at “an unspecified date”.
