1. A man-machine interface in an aerospace craft for conveying a direction of a detected target to a crew of the aerospace craft by a localized sound comprising the steps of:
- (a) obtaining the direction of the detected target;
(b) detecting a crew'"'"'s facial direction;
(c) calculating a direction of the detected target with respect to the crew'"'"'s facial direction from the direction of the detected target and the crew'"'"'s facial direction;
(d) producing the localized sound by localizing a sound used as a sound source in the direction of the detected target with respect to the crew'"'"'s facial direction; and
(e) outputting the localized sound binaurally to the crew by a sound-output device.

Abstract
The direction of a target is determined relative to the facial direction of a crew of an aerospace craft and a localized sound is produced in this direction. This localized sound is then output binaurally to the crew to provide an indication of the location of the target. This use of localized sound allows the crew to rapidly locate targets while reducing eye strain. Pseudo-targets can also be located in a flight simulator.
