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.
