Microsoft has announced plans to release an official SDK beta and a modified piece of hardware which will allow Kinect to work on its Windows operating system.
Hackers have been using Microsoft's motion-sensing peripheral on the PC for quite a while, but Microsoft has now taken the steps to allow a much broader range of developers to get their hands on it.
The Windows version of the peripheral is said to come with a camera that can focus on objects as close as 50cm and it will come with a much shorter USB cable. It will also come with a tweaked firmware to make it more suitable for PC-centric tasks. The release is planned for early 2012.
