Perhaps most importantly, SDK version 1.7 will include "Kinect Fusion," Microsoft's at-home 3D modeling solution that allows the Kinect to capture and fabricate real-time 3D models of people and objects. We first saw this technology in action way back in August of 2011, when the concept surfaced as a Microsoft Research project.
Additionally, the new SDK also includes "Kinect Interactions," which adds support for new gestures such as "push-to-press" and "grip-to-pan," as well as "support for smart ways to accommodate multiple users and two-person interactions," according to Engadget.
