AB  - BACKGROUND: 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. METHOD: 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). RESULTS: 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. 
      CONCLUSION: 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.
