Head motions are tracked with six degrees of freedom (6DOF), specifically yaw, pitch, roll, left/right, up/down and forward/back. Tracking is sensitive enough that only small head movements are required so that the user's eyes never leave the screen. Its main function is inexpensive head tracking in computer games and simulations but can also be used for general computer accessibility, in particular hands-free computing.
