Here we introduce a new database called UBFC-Phys that investigates the link between stress and physiological responses.

The UBFC-Phys dataset is a public multimodal dataset, in which 56 participants underwent an experiment with a rigorous protocol inspired by the well-known Trier Social Stress Test (TSST), and was conducted in three stages: a rest, a speech, and arithmetic tasks with different levels of difficulty.

During the experiment, participants were filmed and wore a wristband that measured their blood volume pulse (BVP) and electrodermal activity (EDA) signals. Before the start of the experiment and after the experiment was completed, participants completed a form to calculate their self-reported anxiety scores. The dataset contains participants’ video recordings and BVP / EDA signals measured during the three tasks, as well as their anxiety scores calculated before and after the experimental sessions.
