Rui Wang‘s book on Augmented Reality with Kinect is a lovely introduction to using the Kinect SDK to create a simple application, which takes the reader through a large amount of information on Kinect in a remarkably short space of time. It holds your hand and walks you, step by step, through the process of creating a “fruit ninja” style game (much beloved of UK Prime Minister David Cameron) and provides detailed and well annotated code samples for you to use.
This short tutorial book is an absolute must for anyone finding their feet with Kinect development, and I would strongly recommend it for any intermediate C++ coder who wants to dip a toe into the world of Natural User Interaction.
Augmented Reality means a lot of different things to a lot of different people, but this is very much in the vein of taking a live video feed and adding CG elements on top. If this is the sort of thing you’re interested in. Be warned however, that it does not cover topics such as AR Markers, which are used a lot in marketing / mobile applications – it is purely focused on the Windows Kinect side of things, at which it does a very good job.
