Augmented Reality with Kinect. If you know C/C++ programming, then this book will give you the ability to develop augmented reality applications with Microsoft's Kinect. By the end of the course you will have created a complete game

Rui Wang

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.

Axure RP 6 Prototyping Essentials. Creating highly compelling, interactive prototypes with Axure that will impress and excite decision makers with this book and

Ezra Schwartz

Wireframes, interactive prototypes, and UX specifications are among the fundamental deliverables of every UX project. They are also the most labor and time intensive to produce due to constant changes in business requirements. Given these circumstances, Axure is quickly taking over as the preferred tool for prototyping. However, prototyping in Axure is strikingly different from the conventional method of producing static wireframes and to rapidly develop interactive prototypes in Axure, you'll need to have a good understanding of the tool and its features.Whether you are an individual practitioner or a member of a UX team, a consultant, or an employee, this book will teach you how to use Axure, one of the leading UX tools. You will learn to use Axure for producing top-quality deliverables and tackling the demands of rapid iterative UX projects of any complexity and size, and for any platform and device.Axure RP 6 Prototyping Essentials takes a very pragmatic approach to showing you how to use Axure and produce impressive deliverables while saving labor and time. You may not be in a position to change how projects are scheduled, budgeted, and managed, but you can be more creative and productive by mastering one of the leading UX tools in the market.After an initial introduction to Axure's user interface, terminology, and features, this book walks you through a medium-size UX project: a digital library that sells books, newspapers, and movies. Although some aspects of the prototyping process are simplified for the sake of clarity and efficiency, the demo project is an opportunity to discuss in context and in sequence topics such as addressing business and technical requirements, handling use cases and flow diagrams, low and high fidelity wireframe construction, interactivity, writing annotations, generating detailed UX specifications, and traceability.For the most part, Axure 6 RP Prototyping Essentials can be read in sequence or used as a reference guide.

Backbase 4 RIA Development. Create Enterprise-grade Rich Internet Applications using the Backbase client framework

Ghica van Emde Boas, Sergey Ilinsky

Backbase is a very powerful and complex JavaScript library, with many user interface components to help make web development easier. It allows the development of Rich Internet Applications (RIA) that run within all major browsers but its powers and complexity mean that the choice of component can be overwhelming. Understanding when and how to use the right component might not always be straightforward. This book makes that easier.This is a practical book that teaches you how to use the Backbase Client Framework effectively, with a complete overview and many examples. A core developer of the framework puts the technologies used into a wider perspective of existing web standards and a seasoned software architect explains why XML-based UI definition produces better web applications.The transparent use of AJAX technologies, for example to submit forms, or to retrieve updates for data grids, can be taken for granted with the Backbase framework. Packed with examples, the book shows you how to get the most from the library of UI components, and then extend the library with its own custom language. With this book in hand, it is easy to enable AJAX within your web application. You will be able to use the Backbase framework effectively, from basic applications to complex, custom-defined UI components.This book contains a complete overview of all the UI libraries available within the Backbase framework and shows examples for each element described.The Backbase framework offers an innovative Tag Definition Language (TDL), which allows developers to create new UI components that can be used as XML elements, in the same way as using the built-in GUI library. Using TDL brings considerable development advantages, and this book explains how.Significant attention is also given to architectural aspects of designing a web-application, showing sample applications using a model-view-controller approach.
