UBFC-Phys

The UBFC-Phys dataset is a public multimodal dataset dedicated to psychophysiological studies. 56 participants followed a three-step experience where they lived social stress through a rest task T1, a speech task T2 and an arithmetic task T3. During the experience, the participants were filmed and were wearing a wristband that measured their Blood Volume Pulse (BVP) and ElectroDermal Activity(EDA) signals. Before the experience started and once it finished, the participants filled a form allowing to compute their self-reported anxiety scores. The dataset contains video recordings and BVP / EDA signals of participants measured during the three tasks, as well as their anxiety scores computed before and after the experience sessions.UBFC-Phys数据集是一款专为心理生理学研究打造的公开多模态数据集。56名参与者参与了三步式实验流程，通过休息任务T1、演讲任务T2与算术任务T3依次经受社交应激。实验过程中，参与者被全程录制影像，同时佩戴腕带采集血容量脉冲（Blood Volume Pulse, BVP）与皮肤电活动（ElectroDermal Activity, EDA）信号。实验开始前与结束后，参与者需填写问卷以计算其自我报告的焦虑评分。本数据集涵盖参与者在三项任务期间采集的影像数据、BVP与EDA信号，以及实验前后计算得到的焦虑评分。
