Synchronized eye tracking across recording modalities

Interactive figure legend

Eye-camera frames and packaged pupil, corneal-reflection, and eye-ellipse fits share a synchronized time axis. Traces report fit area in camera pixels squared; shaded intervals mark likely blinks. Optional interpolation replaces isolated one-to-four-frame outliers for display only and does not alter the released eye-tracking values.
