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.

Handling a failover scenario using Kinects


One of the very useful scenarios where you can use multiple Kinects is failover. Failover is used to make the system more fault-tolerant by providing automatic switching to a redundant or standby system. Here, we can consider Kinect as a system, if you are building one Kinect application that needs to be run constantly to capture data. It could happen, that one system fails (gets disconnected, power turns off) and your application fails to capture data. In such a situation, you can start the other connected sensor automatically to capture data and turn it off once the first device starts again.

You can easily build this scenario with the knowledge you have gained in this chapter. The StatusChanged event handler is the key here. You can monitor sensor status and once it's getting disconnected or powered off, start the other connected sensor.

The following screenshot shows a failover application built using Kinect sensors, where the primary sensor...
