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数据集是一款面向心理生理学研究的公开多模态数据集。共有56名参与者完成了三阶段实验，他们依次经历休息任务T1、演讲任务T2与算术任务T3，以此诱发社交应激。实验过程中，参与者被录制视频，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，参与者填写问卷以计算自我报告的焦虑评分。本数据集包含参与者在三项任务期间采集的视频录像、BVP与EDA信号，以及实验阶段前后计算得到的焦虑评分。
