Motion capture is one of the most talked about and misunderstood technologies in computer animation because of its rocketing popularity and ambiguous implementation. In "Understanding Motion Capture for Computer Animation and Video Games, industry insider Alberto Menache tells the complete story of motion capture, examining its technical details as well as its growth as an industry. Menache's narrative voice and in-depth technical discussions allow the reader to not only learn motion capture, but also to understand the reasons behind its successes, failures, and increasing role in blockbuster films, such as "Batman Forever and "Batman and Robin. With its careful balance between technical analysis and industry trends, "Understanding Motion Capture for Computer Animation and Video Games is the first book to explore the controversial art and practice of modern character animation using motion capture.

Just to add the latest thing in mocap from 2008 - Tea Vui Huang's Mocap Phone is a mobile application that enables a suitable Accelerometer-equipped mobile phone to be a limited 2-axis / 3-axis motion capture device that records human / object movements for applications such as 3D animation, movies and games. The data is exported to the de facto Hollywood special effects mocap standard - Vicon C3D, as well as Autodesk FBX, Acclaim AMC & ASF and a direct Maya MEL format.
