Abstract

The ability of pilots to divide their attention between multiple tasks is critical for aviation safety. Eccentricity and saliency are known visual perception factors for attention. The purpose of this thesis was to examine the effects of eccentricity and saliency on the participants’ transitioning behavior, between an aviation fault management task and a flight monitoring task. This investigation was accomplished by a review of an archival eye-tracking dataset. Eccentricity was found to have no effect on the participants’ eye movement transitioning behavior between the two tasks. Saliency did have an effect, however, suggesting that saliency may guide transitions between tasks. Lastly, combining the effects of eccentricity and saliency, participants’ eye movements transitioned farther between tasks when an area was more salient. This furthermore suggests that saliency may guide transitions between tasks and that pilots will transition farther distances if a task is visually salient.
