Using an Electroencephalography Brain-Computer Interface for Monitoring Mental Workload During Flight Simulation
Bibliographic record
Abstract
Background: The objective of the present research was to investigate the potential of implementing electroencephalography (EEG) in a passive brain-computer interface for monitoring mental workload during virtual reality flight simulation.Most aviation accidents are related to pilot cognition and a mismatch between task demands and cognitive resources.Realtime neurophysiological monitoring that identifies high-workload mental states offers an effective approach for reducing accidents during flight.Method: Non-pilot participants performed simulated flight operations.Workload was manipulated to represent regular flight scenarios by varying navigational difficulty and performing communication tasks.EEG data was collected and used to classify periods of flight as high or medium workload.Results and implications: A classification rate of 75.9% was obtained which provides promise for future use of EEG brain-computer interfaces in aviation practice.The most informative classification features (Alpha and Beta oscillations) may represent components of working memory which corresponds to predictions from a multiple resource theory approach to experimental design.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
