BIRAFFE2

该数据集名为BIRAFFE2，是情感计算实验的产物，通过多种模态捕捉参与者的情感反应，包括心理生理反应、面部表情以及游戏进程。数据集包含了元数据、生物信号（心电图和皮肤电反应）、加速度计和陀螺仪记录、游戏日志、面部情感描述以及屏幕录制。所有数据均带有Unix时间戳以便同步，并以与参与者相关的多种文件形式进行结构化。该数据集涵盖了102名参与者的数据，共有103名参与者参与实验。其任务是对情感进行分类和识别。

The dataset named BIRAFFE2 is a product of affective computing experiments, which captures participants' emotional responses via multiple modalities including psychophysiological reactions, facial expressions, and game session progress. The dataset contains metadata, biological signals (electrocardiogram and galvanic skin response), accelerometer and gyroscope recordings, game logs, facial emotion annotations, and screen recordings. All data are labeled with Unix timestamps for synchronization, and are structured into multiple file types associated with individual participants. This dataset covers data from 102 participants, while a total of 103 individuals participated in the experiments. The core task of these experiments is emotion classification and recognition.
