The six degrees of freedom (6DoF) encompass the natural movement of a person or object in the world, and a 6DoF experience offers twice the freedom of movement of a 3DoF experience. The first three degrees of freedom are rotational movement along an axis which is supported in most VR experiences, and the second three degrees are translational movement along an axis which require a VR system with support for positional tracking like Oculus Rift, HTC Vive or Playstation VR. Specifically, the six degrees of freedom include; yaw (rotating horizontally side-side), pitch (rotating vertically up or down), roll (rotating gaze at an angle), slide or sway (moving left or right), heave (moving up or down), surge (moving forward or backward).
