Claim 16:
17. A surgical system comprising:
a sensor assembly configured to:
identify a first location of a first fiducial marker disposed on a frame of a tracking device, the tracking device configured to be mounted to a patient, wherein the first fiducial marker is configured for use with a surgical navigation system, and
identify a second location of a second fiducial marker associated with an augmented reality marker assembly, the augmented reality marker comprising a plurality of fastening mechanisms, the plurality of fastening mechanisms configured to removably attach the augmented reality marker assembly to the frame such that the augmented reality marker assembly assumes a fixed orientation with respect to the frame, wherein the second fiducial marker is configured for use with an augmented reality system; and

a control system communicably connected to the sensor assembly, the control system configured to:
determine a first three-dimensional orientation of the patient by locating the first fiducial marker via the sensor assembly,
determine a second three-dimensional orientation of the augmented reality marker assembly by locating the second fiducial marker via the sensor assembly, and
determine a relationship between the first three-dimensional orientation and the second three-dimensional orientation according to the fixed orientation of the augmented reality marker assembly relative to the tracking device.
