Operating an aircraft is associated with a large mental workload; however, knowledge of the mental workload of ROV operators is limited. The purpose of this study was to establish a digital system for assessing the mental workload of remotely operated vehicle (ROV) operators using hemodynamic parameters, and compare results of different groups with different experience levels.
Forty-one trainee pilots performed flight tasks once daily for 5 consecutive days in a flight simulation. Forty-five pilots experienced pilots and 68 experienced drivers were also included. Hemodynamic responses were measured by functional near-infrared spectroscopy (fNIRS).
The median duration of peak oxyhemoglobin was 147.13 s (interquartile range [IQR] 21.97, 401.70 s) in the left brain and 180.74 s (IQR 34.37, 432.01 s) in the right brain in the experienced pilot group, and 184.42 s (IQR 3.41, 451.81 s) on day 5 in the left brain and 160.30 s (IQR 2.62, 528.20 s) in the right brain in the trainee group.
Navigation training reduces peak oxyhemoglobin duration, and may potentially be used as a surrogate marker for mental workload of ROV operators. Peak oxyhemoglobin concentration during s task may allow development of a simplified scheme for optimizing flight performance based on the mental workload of a pilot.
操作飞机与较大的心理工作量相关；然而，ROV 操作人员的心理工作量的知识是有限的。本研究的目的是建立一个使用血流动力学参数评估遥控潜水器（ROV）操作人员心理工作量的数字系统，并比较不同经验水平的不同组的结果。
41 名受训飞行员在飞行模拟中每天进行一次飞行任务，连续进行 5 天。还包括 45 名有经验的飞行员和 68 名有经验的驾驶员。血流动力学反应通过功能近红外光谱（fNIRS）测量。
在有经验的飞行员组中，左脑的峰值氧合血红蛋白中位数持续时间为 147.13s（IQR 21.97，401.70s），右脑为 180.74s（IQR 34.37，432.01s），在受训飞行员组中，左脑的中位数持续时间为 184.42s（IQR 3.41，451.81s），右脑为 160.30s（IQR 2.62，528.20s）。
导航训练减少了峰值氧合血红蛋白持续时间，并且可能潜在地用作 ROV 操作人员心理工作量的替代标志物。任务期间的峰值氧合血红蛋白浓度可能允许根据飞行员的心理工作量开发一种优化飞行性能的简化方案。
