A method for providing a pilot with information associated with at least one
region
of a field of view visible to the pilot from within a cockpit without requiring
a visual display. The method includes the steps of determining an eye gaze direction
relative to a given frame of reference for at least one eye of the pilot, determining
a reference direction relative to the given frame of reference, comparing the eye
gaze direction with the reference direction, and if the eve gaze direction and
the reference direction are equal to within a given degree of accuracy, generating
audio output audible to the pilot and indicative of information associated with
the reference direction.
