A system for tracking a gaze of an operator includes a head-mounted eye tracking
assembly, a head-mounted head tracking assembly and a processing element. The head-mounted
eye tracking assembly comprises a visor having an arcuate shape including a concave
surface and an opposed convex surface. The visor is capable of being disposed such
that at least a portion of the visor is located outside a field of view of the
operator. The head-mounted head tracking sensor is capable of repeatedly determining
a position of the head to thereby track movement of the head. In this regard, each
position of the head is associated with a position of the at least one eye. Thus,
the processing element can repeatedly determine the gaze of the operator, based
upon each position of the head and the associated position of the eyes, thereby
tracking the gaze of the operator.
