Attentional issues in superimposed flight symbology

Abstract

The mechanisms of the failure to simultaneously process HUD superimposed symbology and the out-the-window view may lie in the many cognitive and perceptual cues that inform the pilot that the HUD, although collimated at infinity, is an instrument on the aircraft. Thus, in relation to the world scene, the HUD forms a perceptually segregated object that has a different frame of reference. Research is being explored to determine the mechanisms in this problem, and to develop advanced designs that maximize the cognitive and perceptual compatibility of the superimposed symbology by integrating the important information into the world scene.
