Presentation investigating whether bicyclists' stress/arousal can be captured using electrodermal activity (EDA) in a VR bicycle simulator. Covers EDA basics, experiment design (5 VR bicycling environments, 380 m each, 89 participants), sensor setup (Shimmer3 GSR+ on inner-wrist, 16 Hz), signal quality issues, preprocessing choices (artefact correction, Gaussian smoothing window=48), post-processing (SCR threshold set to 0.03 μS, standardisation to T-scores), and results showing higher arousal before intersections and no significant differences across environment types in mixed-effects models. Concludes EDA provides granular, real-time arousal data but requires many processing steps and transparent reporting.
