A head-mounted display system includes an imaging camera for capturing a view
of
a workspace located below the head-mounted display system, the imaging camera positioned
at a downward pitch angle for capturing an image of the workspace. The system further
includes a tracking camera aligned in substantially the same yaw as the imaging
camera, the tracking camera for capturing a tracking image including a marker structure,
and a display which displays a view of the workspace captured by the imaging camera
augmented by a virtual image generated by a processor and registered according
to the tracking image.
