An optical see-through, augmented reality display was used to study subjects' ability to detect aircraft maneuvering and landing at the Dallas Ft. Worth International airport in an ATC Tower simulation. Subjects monitored the traffic patterns as if from the airport's western control tower. Three binocular fields of view (14 deg, 28 deg and 47 deg) were studied in an independent groups' design to measure the degradation in detection performance associated with the visual field restrictions. In a second experiment the 14 deg and 28 deg fields were presented either with 46% binocular overlap or 100% overlap for separate groups. The near asymptotic results of the first experiment suggest that binocular fields of view much greater than 47% are unlikely to dramatically improve performance; and those of the second experiment suggest that partial binocular overlap is feasible for augmented reality displays such as may be used for ATC tower applications.Ellis, Stephen R. and Adelstein, Bernard D. and Reisman, Ronald J. and Schmidt-Ott, Joelle R. and Gips, Jonathan and Krozel, Jimmy and Cohen, Malcolm (Technical Monitor)Ames Research CenterDISPLAY DEVICES; VISUAL FIELDS; FIELD OF VIEW; AIR TRAFFIC CONTROL; TRAFFIC; TOWERS; SIMULATION; DETECTION; DEGRADATION; AIRPORT TOWERS; AIRCRAFT MANEUVERS; AIRCRAFT DETECTION...
