Wrist-worn sensor validation for heart rate variability and electrodermal activity detection in a stressful driving environment
Description
The current dataset contributes to assess the accuracy of the Empatica 4 (E4) wristband for the detection of heart rate variability (HRV) and electrodermal activity (EDA) metrics in stress-inducing conditions and growing-risk driving scenarios. Heart Rate Variability (HRV) and ElectroDermal Activity (EDA) signals were recorded over six experimental conditions (i.e., Baseline, Video Clip, Scream, No Risk Driving, Low-Risk Driving, and High-Risk Driving) and by means of two measurement systems: the E4 device and a gold standard system. The raw quality of the physiological signals was enhanced by means of robust semi-automatic reconstruction algorithms. Heart Rate Variability time-domain parameters showed high accuracy in motion-free experimental conditions, while Heart Rate Variability frequency-domain parameters reported sufficient accuracy in almost every experimental condition. Folder 01 contains both HRV and EDA parameters for every experimental condition, according to the Gold Standard measurement system and the Empatica 4 device, in two separate Excel files. Folder 02 contains supplementary material on the assessment of the signals quality. Folder 03 contains the Bland-Altman plot for each HRV and EDA parameter and for each condition (1 .png file per each parameter), and an excel file that resumes the Bland-Altman analyses numerical outcomes.
