Effects of Intelligent Information Systems on Visual Search Characteristics of Pilots
To investigate the visual search characteristics of pilots'use of intelligent information systems,a comparison experiment was designed with the level of information systems(interactive system and electronic manuals)as independent variables and visual search characteristics(visual search characteristics and performance levels)as dependent variables.The eye-tracking data of each human-computer interaction interface that 20 airline pilots paid attention to in the simulator experiment scenarios were recorded.According to statistical analysis and the evaluation model of visual search performance,these pilots'visual search characteristics and performance levels could be presented.The results show that there are significant differences in the visual search characteristics of the two groups of pilots,such as the total fixation duration,the percentage of the total fixation duration,and numbers of fixation.With the improvement of the intelligence level of the information system,the visual search performance level of pilots in the scenarios of engine failure and flap locked effectively improves and the workload decreases.Thus,it is verified that the improvement of the intelligence level of the information system can have a positive effect on the pilot's work performance in complex scenarios,and can provide theoretical references for the design,optimization and iteration of the cockpit human-computer interaction interface to ensure flight safety.
