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 数据集为一项面向心理生理学研究的公开多模态数据集。该数据集涉及56名参与者，经历了一个三阶段的过程，通过休息任务T1、演讲任务T2和算术任务T3来体验社会压力。在整个体验过程中，参与者被摄录，并佩戴测量其血容量脉搏（BVP）和皮肤电活动（EDA）信号的腕带。在体验开始前和结束后，参与者填写问卷，以计算其自我报告的焦虑分数。该数据集包含参与者在三个任务期间测量的视频记录和血容量脉搏/皮肤电活动信号，以及体验前后计算出的焦虑分数。
