Physiological Markers of Cybersickness in Virtual Reality: Skin Conductance Correlates with Momentary Cybersickness Across Time.

This exploratory study investigates the feasibility of using physiological measures to assess cybersickness during virtual reality (VR) immersion, with a particular focus on within-subject correlations to explore the relationship between the cybersickness self-report and physiological measures. The cybersickness-inducing simulation showed a significant increase in cybersickness self-report, a significant increase in electrodermal activity (EDA) measures, skin conductance level (SCL), and skin conductance response (SCR), although no such difference existed for heart rate beats per minute (BPM). Importantly, a repeated measures correlation analysis revealed a significant positive within-individual relationship between self-reported cybersickness and EDA measures (SCL and SCR). These findings suggest that EDA measures may serve as a valuable continuous physiological measure of cybersickness during VR immersion.
