[[Tracking]] allows the [[VR]] or [[AR]] system to know where your head ([[HMD]]), hands and other body parts ([[Input Device]]s) are looking and moving. Tracking is important to accurately render the virtual world to match your physical positions and movements. | [[Tracking]] allows the [[VR]] or [[AR]] system to know where your head ([[HMD]]), hands and other body parts ([[Input Device]]s) are looking and moving.

Tracking can either be 3DOF (rotation only) or 6DOF (position and rotation). Early VR tracking technology in the 1990s used magnetic tracking systems that used either AC magnetics or DC magnetics depending on the provider. | |||
The [[Magic Leap 1]] uses 6DOF magnetic tracking for its controller, but it is poor quality. | |||
