基于以往的研究显示有用的空间统计检测随机分布的眼睛注视，本研究调查了专业飞行员从事模拟飞行的眼行为。眼球注视的分布被用作心理负荷的间接指标：在模拟飞行的不同阶段（起飞到着陆）记录眼球运动，并使用空间统计算法进行分析。结果表明，敏感性的空间分散指数的变化，心理工作量：较高的出发和降落，较低的爬升和下降，最低的巡航阶段。这一发现提供了额外的证据，固定分布的实用性作为一个实时的测量心理工作量，因此，作为一个触发器的自适应自动化。
Based on previous research showing the usefulness of spatial statistics in detecting randomness in the distribution of eye fixations, this study investigated the ocular behavior of professional pilots engaged in a simulated flight. The distribution of eye fixations was used as an indirect index of mental workload: Eye movements were recorded during the different phases (departure to landing) of a simulated flight and were analyzed using spatial statistics algorithms. Results showed sensitivity of spatial dispersion indices to variations in mental workload: higher during departure and landing, lower during climb and descend, and the lowest during the cruise phase. This finding provides additional evidence of the utility of fixations distribution as a real-time measure of mental workload and, consequently, as a trigger for adaptive automation.
