Dedicated stress-benchmark evaluation of EgoHRV

Conduct a dedicated stress-benchmark evaluation to determine whether continuous heart rate variability estimates from egocentric gaze video can support stress-related inference beyond treating heart rate variability as a stress-related autonomic marker.

Background

The paper uses heart rate variability as an established proxy for autonomic stress responses but does not train or evaluate a direct stress-labeling task. Consequently, the demonstrated experiments concern heart rate and heart rate variability estimation and proficiency prediction rather than validated stress recognition. A dedicated benchmark would assess the practical value of the proposed egocentric physiological estimates for stress-aware applications.
