This is a project I have to do for my "virtual environments" laboratories for university, where we have to use a couple of alternative (as in "alternative to mouse and keyboard") input methods. I intend to create a pool game where you can control the play by using PS Move Motion controller and use steroscopic vision.

As of Nov 2011 this is work in progress, but the PS Move Motion Controller communication is working and you can track it using OpenCV/Hough transform.

Feel free to use this project, this is GPL3. I think you may be interested particularly in the MoveThread class which is a sort-of-wrapper for communicating with the motion controller written for Qt.

This project is based on excellent work by Pascal Brisset (http://www.pabr.org/linmctool/linmctool.en.html) and H. Kaufmann (http://code.google.com/p/moveonpc/)
