positional tracking

VR systems with support for positional tracking, like the Rift or Vive, detect the position of the system relative to the world around it. This is done with the help of sensors, which record signals from the headset or other VR equipment as it moves within a defined space, allowing the motion of the user to be reflected in the virtual world. Positional tracking allows the user to experience the full 6DoF, which makes true immersion possible.
