Visual Requirements Study for Head-Up Displays

Abstract

An experimental study was conducted to determine the binocular disparity tolerances for pilots viewing dynamic head-up display images against a moving real world background. An existing head-up display simulator, which could generate images with controlled disparities for each eye, was modified to incorporate a background of projected motion pictures taken in flight at low altitudes. Six pilots served as test subjects, three from the Army Aviation School and three from the Naval Air Test Center. The results indicate maximum disparity levels for sustained comfortable viewing of 1.0 milliradian for vertical and convergent horizontal disparities, and 2.5 milliradians for divergent horizontal disparities. These results are the same as those obtained with the display viewed against a static real world background in a preceding study involving a different group of subjects.
