Current Research Applications

Air Traffic Management Systems

  1. This research involves a wide vareity of methods to aid air traffic controllers with managing multiple dynamic aircraft. Eye tracking data analysis is performed to further understand the cognitive process of controllers as they scan aircraft, then identify and solve conflicts between them. This understanding leads to detailed characterization of scanning strategies and more effective training methods.

    The image above on the left shows a zoomed-in area of a realistic simulation of an air traffic radar display. Each green diamond represents an aircraft, the line projecting out represents its travel direction, and the text is a data tag listing the flight number, altitude, and velocity respectively. The image on the right shows a 1.5 minute eye movement scan of an air traffic controller overlaid on a scenario including 20 aircraft. The circled numbers show the order in which the eye fixations were made and the white lines connecting them are rapid movements between fixations. There are many ways to characterize these scanning startegies including categories such as duration, number of comparisons between aircraft, and search patterns.

  2. The image to the left represents a simulated RADAR display of low altitude Enroute airspace. The Green dot shows the eye fixation location of an ATC. The green lines represent saccades of the eye movement. The image on the right represents the directed weighted network (DWN) representation of the AOI fixation sequence data of the ATC. The size and the colour of the nodes (AOIs) are proportional to the number of times the AOIs are visited and to the amount of eye fixation duration that happened on the AOIs respectively (Red means higher fixation duration yellow means lower fixation duration).

  3. In collaboration with the FAA, we have worked on (1) automating the process of mapping eye tracking data to multiple moving objects, and (2) developing eye tracking data visualization methods.
