Monitoring army drivers' workload during off-road missions: an experimental controlled field study

摘要: Abstract We studied the validity of electroencephalographic (EEG) and gaze indices to discriminate task load variations in professional Army drivers while performing real training exercises with a Light Multirole Vehicle non-combat scenarios. Twenty-two non-commissioned officers from Spanish carried out two sets standardized driving exercises, low high maneuver complexity (off-road navigation vs. slalom on dirt road). They performed both without secondary auditory-vocal digit span forward task. Throughout we simultaneously recorded drivers’ EEG activity. also assessed perceived performance. found that neural activation changed exercise complexity. Particularly, signal ratio between Frontal-Theta Parietal-Alpha power spectra, known as workload index, was higher during most complex exercise. This index not affected by dual tasking. Furthermore, level uncertainty position, measured entropy, increased Dual tasking did increase dispersion, but only when less Perceived sensitive Performance vary across exercises. Our results support physiological monitoring training, even extreme environments, is feasible can give objective measurements changes over time minimally invasive fashion.
