Overview of this book

Kinect has been a game-changer in the world of motion games and applications since its first release. It has been touted as a controller for Microsoft Xbox but is much more than that. The developer version of Kinect, Kinect for Windows SDK, provides developers with the tools to develop applications that run on Windows. You can use this to develop applications that make interaction with your computer hands-free. This book focuses on developing applications using the Kinect for Windows SDK. It is a complete end to end solution using different features of Kinect for Windows SDK with step by step guidance. The book will also help you develop motion sensitive and speech recognition enabled applications. You will also learn about building application using multiple Kinects.The book begins with explaining the different components of Kinect and then moves into to the setting up the device and getting thedevelopment environment ready. You will be surprised at how quickly the book takes you through the details of Kinect APIs. You will use NUI to use the Kinect for Natural Inputs like skeleton tracking, sensing, speech recognizing. You will capture different types of stream, and images, handle stream event, and capture frame. Kinect device contains a motorized tilt to control sensor angles, you will learn how to adjust it automatically. The last part of the book teaches you how to build application using multiple Kinects and discuss how Kinect can be used to integrate with other devices such as Windows Phone and microcontroller.

Bones – connecting joints


Bones are the visual representation between joints. They don't have any physical presence and that is why we are calling them virtual. The complete hierarchy of a skeleton is composed of a series of bones, which is the connection of all the tracked joints with the joint collection of that skeleton.

The skeleton representation is a hierarchical representation of a bone and each bone in a skeleton hierarchy has a parent joint and a child joint. This also implies that every joint can be a parent and child joint unless it is a leaf joint, such as Head Joint, Hand Joints, and so on. Parent joints are always above child joints in the hierarchy.

For example, consider the Right Leg of a skeleton which consists of Hip Center, Hip Right, Knee Right, Ankle Right, and Foot Right joints. Now for a bone between Hip Center and Hip Right, Hip Center is the parent and Hip Right is the child. Similarly, for another bone between Hip Right and Knee Right, Hip Right is a parent joint...
