The Eye Movement Experiment and the Usability Evaluation of the Fighter Cockpit Digital Interface

The relationship between the eye movement experiment and the quantitative evaluation of the visibility and usability of the fighter cockpit digital interface is put forward. After analyzing the data of the eye movement experiment of simulated fighter cockpit digital interface, we can demonstrate that the four kinds of quantitative data of the eye movement which include the pilot's gaze point coordinate, the gaze point number, the pupil frequency and the event time are very sensitive to the visibility and usability evaluation of the cockpit digital interface, and that the figure of gaze point sequence can apply to the usability evaluation of the interface very well. Furthermore, we infer that the eye movement experiment can reveal the pilot's visual process and cognitive activity, which will have a great practical significance to evaluate the usability and optimize the interface.
