Tracking allows the VR or AR system to know where your head (HMD), hands and other body parts (Input Devices) are looking and moving. Tracking is important to accurately render the virtual world to match your physical positions and movements.
Rotational Tracking
Rotational tracking tracks an object's movement in all 3 rotational directions: pitch, yaw, and roll. Rotational tracking is usually performed by IMUs such as accelerometers, gyroscopes and magnetometers.
Positional Tracking
Positional tracking tracks an object's movement in all 3 translational directions: forward/back, up/down, left/right. Positional tracking is usually more difficult than rotational tracking.
