Natural head motion for 3D social games

Natural head motion is the key component in Virtual Reality systems where users are immersed via personal eyewear. The advent of webcam tracking technologies made head motion available on every desktop, for any 3D game, calling for revised methods of handling user head motion in new, non-immersive settings. We present several novel techniques of using head motion in 3D social games. We show that head tracking is not only a useful, but also an enabling technology, that creates new means of interaction between players, makes gameplay more personal and game controls more flexible.
