Microsoft today released an updated version of the Kinect for Windows SDK 2.0 public preview which includes more than 200 improvements to the core SDK. It also includes Kinect Fusion tool kit, which provides higher resolution camera tracking and performance. The Kinect for Windows v2 sensor gives developers more of the precision, responsiveness, and intuitive capabilities they need to develop interactive voice and gesture-based applications.
The updated SDK also includes substantial improvements in the tooling, specifically around Visual Gesture Builder (VGB) and Kinect Studio, and it offers 10 new samples (such as Discrete Gestures Basics, Face, and HD Face Basics) to get you coding faster. All of this adds up to a substantially more stable, more feature-rich product that lets you to get serious about finalizing your applications for commercial deployment and, later this year, for availability in the Windows Store.
As you already know the SDK is free and there will be no fees for runtime licenses of commercial applications developed with the SDK.
