UBFC-Phys : A Multimodal Dataset For Psychophysiological Studies Of Social Stress

The UBFC-Phys dataset is a public multimodal dataset dedicated to psychophysiological studies. It first aimed at physiological signal analysis during social stress. 56 participants followed a three-step experience that involved a rest task T1, a speech task T2 and an arithmetic task T3. During the experience, the participants were filmed (using the EO-23121C camera by Edmund Optics), and were wearing a wristband (Empatica E4) that measured their Blood Volume Pulse (BVP) and ElectroDermal Activity (EDA) signals. Two levels of difficulties (denoted as test and ctrl) were established and one of them was randomly assigned to each participant. Before the experience started and once it finished, the participants filled a form allowing to compute their self-reported anxiety scores.
