Augmented Reality with Kinect

Overview of this book

Microsoft Kinect changes the notion of user interface design. It differs from most other user input controllers as it enables users to interact with the program without touching the mouse or a trackpad. It utilizes motion sensing technology and all it needs is a real-time cameras, tracked skeletons, and gestures. Augmented Reality with Kinect will help you get into the world of Microsoft Kinect programming with the C/C++ language. The book will cover the installation, image streaming, skeleton and face tracking, multi-touch cursors and gesture emulation. Finally, you will end up with a complete Kinect-based game. Augmented Reality with Kinect will help you get into the world of Kinect programming, with a few interesting recipes and a relatively complete example. The book will introduce the following topics: the installation and initialization of Kinect applications; capturing color and depth images; obtaining skeleton and face tracking data; emulating multi-touch cursors and gestures; and developing a complete game using Kinect features. The book is divided in such a way so as to ensure that each topic is given the right amount of focus. Beginners will start from the first chapter and build up to developing their own applications.

Choosing image stream types


The Microsoft Kinect SDK supports several types of image streams. In the example from the previous chapter, we started the device with the following options:

DWORD nuiFlags = NUI_INITIALIZE_FLAG_USES_SKELETON | NUI_INITIALIZE_FLAG_USES_COLOR | NUI_INITIALIZE_FLAG_USES_DEPTH;
hr = context->NuiInitialize( nuiFlags );

It can be concluded from the enumeration values that three types of data will be allocated in the current application: the skeleton, the color, and the depth.

The color and depth data are of course necessary here because we are going to make use of them soon. The skeleton data will be first used in Chapter 4, Skeletal Motion and Face Tracking. Besides this, Kinect even provides two more types of data for us to select at the beginning of the application:

  • NUI_INITIALIZE_FLAG_USES_AUDIO: This provides the audio data from the microphone array located at the bottom of the device.

  • NUI_INITIALIZE_FLAG_USES_DEPTH_AND_PLAYER_INDEX: This provides the depth data...
