Abstract:
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 comprising the steps of:(i) determining an eye gaze direction relative to a given frame of reference for at least one eye of the pilot by: (a) employing a helmet-mounted system to derive direction information related to a relative eye gaze direction for at least one eye of the pilot relative to a helmet worn by the pilot, (b) deriving position information related to a position of said helmet within a cockpit, and (c) processing said direction information and said position information to derive said eye gaze direction relative to a frame of reference associate with said cockpit; (ii) determining a reference direction relative to said given frame of reference; (iii) comparing said eye gaze direction with said reference direction; and (iv) if said eye gaze direction and said reference direction are equal to within a given degree of accuracy, generating audio output audible to the pilot and indicative of information associated with said reference direction.
