Abstract
The goal of this study is to explore how ocular behavior is different in groups that possessed varying levels of performance in dynamic control tasks with complex visual components. Twenty two university students participated in this study by operating a human-in-the-loop HITL simulator. The participants were asked to identify unknown air tracks and take proper actions to defend a battleship. During the experiment, a head-mounted eye-tracking device was used continuously to record participants' visual attention span regarding the normalized coordinates of their gaze points. In the current study, fixation duration was the main eye-tracking metrics. Air track identification accuracy and the NASA Task Load Index NASA-TLX were also used to measure participants' task performance and overall subjective mental workload.
