Chapter 9. Building Gesture-controlled Applications

You've learned about the different features of the Kinect for Windows SDK; also you've seen how things work in the Kinect for Windows sensor and how you can interact with the sensor using the Kinect for Windows SDK APIs. We have also explored the Kinect color stream, depth stream, and also skeleton tracking, along with the underlying techniques. However, there is one area that is conspicuous by its absence. Can you guess what it is? It's gestures. Gesture recognition is one of the hallmarks of the Kinect. The amount of innovation and research that has gone into the development of gesture technology is unparalleled. Gestures, in layman's terms, can be described as bodily actions that convey a message. This simple action could be a waving of the hands, moving of wrists, or a complicated action involving multiple body parts. The technology used for identifying gestures and converting them to a form that can be recognized by gesture-based devices...
