A system determines a location of a sighting apparatus for a weapon simulator in three-dimensional space using a three-dimensional positional tracking system. Upon placement of a virtual reality (VR) head mounted display (HMD) in proximity to the sighting apparatus for the weapon simulator, the system determines a location of the VR HMD in three-dimensional space using the tracking system. The system then analyzes the relationship between the locations of the virtual trainer and the VR HMD, and upon determining that the VR HMD is properly positioned in relation to the virtual trainer, the system locks a visual feed to the VR HMD.
