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.

Sound source localization


The fundamentals of sound source localization are based on identifying the sound source angle and the beam angle, and the response to the changes as well.

Sound source angle

The source angle is the range area that Kinect can listen to and it's valid from +50 to -50 radians. The KinectAudioSource class has the SoundSourceAngle property, which returns the current source angle.

Note

Once we start the Kinect audio source, the SoundSourceAngle property starts updating automatically.

The Kinect source angle is calculated based on the current Kinect camera coordinates, where the x and y axes define the horizontal plane.

You can use the MaxSoundSourceAngle and MinSoundSourceAngle properties of the KinectAudioSource class to get the maximum and minimum values of the sound source angle.

The SDK raises the SoundSourceAngleChanged event if there is any change in the source angle. The SoundSourceAngleChangedEventArgs class contains two properties that return the current source angle...
