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.

Basic gesture recognition


The fundamental approach of gesture recognition is to play around with the skeleton's joint points and apply basic logic to perform some action. Basic gesture detection depends on some pre-defined set of conditions, known as the result set. If the performed action is matched with the result set, we can say that the user has performed a certain gesture, otherwise not.

Note

Implementing the basic gestures is relatively easy and straightforward, however, this approach is the fundamental base of building any kind of gesture-controlled application.

In this section, we will learn a few approaches to recognize the basic gestures and will build an application that leverages the basic gesture recognition approach.

Gesture-detection technique

Gesture detection depends on the tracked joints of the human skeleton because we define the condition of gestures based on the joints. Before jumping into further details, let's have a quick look at the representation of skeleton joints.
