Pilot Cognitive Workload & Heart-Rate Variability

A physiologically grounded autonomic-nervous-system model: raise a pilot's cognitive workload and change the breathing rate to watch heart-rate variability shift, rendered live as a 3D Poincaré plot with SD1/SD2 ellipse, RMSSD and LF/HF readouts.

This simulator models the autonomic nervous system signature that neuroergonomic pilot-training research monitors in real time: beat-to-beat RR intervals generated from a workload-dependent superposition of a ~0.1 Hz low-frequency (baroreflex/Mayer-wave) rhythm and a respiration-locked high-frequency rhythm. Raise cognitive workload and the mean heart rate climbs while vagally-mediated high-frequency variability collapses — the same sympathovagal shift used to infer pilot stress from cockpit biometrics. Every beat is plotted live on a 3D Poincaré plot with its SD1/SD2 ellipse, alongside RMSSD, heart rate and SD2/SD1 readouts, so the abstract "workload → reduced HRV" relationship becomes something you can watch happen, beat by beat.
