In this study, a situation-augmented display for unmanned aerial vehicle (UAV) monitoring was designed, and its effects on operator performance and mental workload were examined. The display design was augmented with the knowledge that there is an invariant flight trajectory (formed by the relationship between altitude and velocity) for every flight, from takeoff to landing. 56 participants were randomly assigned to the situation-augmented display or a conventional display condition to work on 4 (number of abnormalities) x 2 (noise level) UAV monitoring tasks three times. Results showed that the effects of situation-augmented display on flight completion time and time to detect abnormalities were robust under various workload conditions, but error rate and perceived mental workload were unaffected by the display type. Results suggest that the UAV monitoring task is extremely difficult, and that display devices providing high-level situation-awareness may improve operator monitoring performance.
在这项研究中，设计了一种用于无人机（UAV）监控的情境增强显示，研究了它对操作人员绩效和心理工作量的影响。该显示设计通过利用以下知识进行了增强：从起飞到降落，每个飞行都有一个不变的飞行轨迹（由高度和速度之间的关系形成）。56 名参与者被随机分配到情境增强显示或传统显示条件下，三次完成 4（异常数量）x2（噪声水平）个 UAV 监控任务。结果表明，在各种工作负荷条件下，情境增强显示对飞行完成时间和检测异常的时间的影响是稳健的，但错误率和感知心理工作量不受显示类型的影响。结果表明，UAV 监控任务极其困难，提供高水平情境感知的显示设备可能会提高操作人员的监控性能。
