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.

Multitouch systems


The word multitouch refers to the ability to distinguish between two or more fingers touching a touch-sensing surface, such as a touch screen or a touch pad. Typical multitouch devices include tablets, mobile phones, pads, and even powerwalls with images projected from their back.

A single touch is usually done by a finger or a pen (stylus). The touch sensor will detect its X/Y coordinates and generate a touch point for user-level applications to use. If the device simultaneously detects and resolves multiple touches, user applications can thus efficiently recognize and handle complex inputs.

Gestures also play an important role in multitouch systems. A gesture is considered as a standardized motion, which can be used distinctly to represent a certain purpose. For example, the "tap" gesture (hit the surface lightly and release) always means to select and start a program on mobile phones, and the "zoom" gesture (move two fingers towards or apart from each other), or sometimes...
