In [[VR]] and [[AR]], fiducial markers are used for [[positional tracking]] of [[HMD]]s and [[Input Devices]]. Fiducial markers can be utilized in both [[inside-out tracking]] and [[outside-in tracking]]. In inside-out tracking, markers such as QR codes can be placed in the environment to serve as reference points. In outisde-in tracking, markers such as light-emitting diodes can be placed onto the object so it can be tracked by the external camera(s).
 Tracking systems that do not use fiducial markers are called [[Markerless tracking]].
