为了合理地确定飞行员在执行飞行任务时的视觉信息流强度,开发了飞机座舱显示界面仿真模型,以被试的正确反应率和反应时间来评价作业绩效.通过实验和数据分析得到以下结果:所建立的视觉信息流模型中视觉信息流强度曲线符合正态分布.不同的视觉信息量完成任务差异显著,信息量增加到一定程度时辨识变慢,出现错误的几率升高;在相同视觉信息量情况下,夜晚与白天、动态与静态执行任务辨识和绩效差异显著,白天要比夜晚、静态要比动态辨识效率和绩效更好.
In order to reasonably determine the intensity of visual information flow of pilots during the flight mission, a simulation model of the cockpit display interface was developed to evaluate the job performance based on the correct response rate and reaction time of the participants.The following results were obtained through the experiment and data analysis: The visual information flow intensity curve in the established visual information flow model is in accordance with the normal distribution.Different visual information volume achieves significant differences in tasks, and when the amount of information increases to a certain degree, the recognition becomes slow and the probability of errors increases; in the same visual information amount In the case of night and day, task identification and performance of dynamic and static tasks are significantly different. During the day and night, static and dynamic performance are better than dynamic identification.
