Designs and Algorithms to Map Eye Tracking Data with Dynamic Multielement Moving Objects

Area of interest (AOI) and visual angle accuracy error: The AOI approximates the shape of the object and should be slightly bigger than the original object size considering the visual angle error. The object consists of the aircraft itself (shown as a small diamond shape), the direction indicator (currently flying east), the data block (aircraft ID: UAL 480, altitude: cruising at 28000 ft., computer ID: 781, and speed: 480 knots), and the leader line which points to its corresponding aircraft.
