A FixationClick Count Signature as a Visual Monitoring Enhancement Feature for Air Traffic Controllers This paper presents an approach to capture the deliberate perception and comprehension behavior of Air Traffic Controllers (ATCOs) by utilizing their eyeball and hand movement. Hence, a new fixationclick count signature, involving ATCOs fixating on aircraftxe2x80x99s track or label, before performing respective commands within a specified operational duration, is derived. 88 onehour real time simulations involving a remote eye tracker and scenarios mimicking actual air traffic were conducted for participants from three expertise levels. Results show that this signature is common amongst all participants for both incoming and outbound aircraft. Furthermore, addition visual attention span is required with increasing commands issued, as a higher fixation count is exhibited with more clicks performed for the onehour duration. This signature could also be used to differentiate the expertise levels of ATCOs, as experts were found to exhibit the most fixation count across all click counts, followed by intermediates and novices.

VisualizationGuided Attention Direction in Dynamic Control Tasks In highpaced applications like air traffic control, disaster management, and medical triage, information is often routed through a central location such as a dispatch or control center. In this work, we introduce a set of colorcoded and gazeaware visualizations designed to simultaneously manage both information priority and user attention. These notifications are unique in that they not only respond to whether or not they have been observed by the user, but they use color to represent the priority of the object to assist processing of other incoming information in the environment. We built both headsup display (HUD)based and insitu information management paradigms and combined these with gaze and color visualizations. In an interactive virtual reality (VR) control center simulation, HUD visualizations slightly reduced unnecessary head movement without sacrificing performance, but were distracting to participants.
