Here's some research I found on the subject: Design of a Body-Driven Multiplayer Game System (Sami Laakso and Mikko Laakso)
"So far camera-based user interfaces have been used in various entertainment or education applications, ranging from interactive dance space [Sparacino 2001] to martial arts training [Hämäläinen et al. 2005]. Today there are also several commercial camerabased body-driven game systems available, both complete game systems such as Mandala GX System by Vivid Group [http://www.vividgroup.com/] and home-sized devices such as Eyetoy for Sony PlayStation 2 [http://www.fmod.org/]."; "The software was coded in C++ on a Windows platform. The computer vision component was developed on top of the video-processing platform, EyesWeb Design of a Body-Driven Multiplayer Online Game System ● 7 ACM Computers in Entertainment, Vol. 4, No. 4, October 2006. [http://www.eyesweb.org/], using Intel Integrated erformance Primitives (Intel IPP) [http://www.intel.com/software/products/ipp/], and the Open Source Computer Vision Library http://www.intel.com/technology/computing/opencv/] for additional image processing. The 3D graphics output was obtained by using OpenGL, and audio effects obtained with an F-Mod audio engine [http://www.fmod.org/] and the Simple Direct Media Layer [http://www.libsdl.org/]."; (This is an old project :-) http://www.kickasskungfu.net/en/) Other articles tha might interest you: (Not public so I cannot share with the list.
