Loughborough University Multimodal Emotion Dataset-2

Loughborough University Multimodal Emotion Database-2 (LUMED-2) is a new multimodal emotion dataset that was created by the researchers of Loughborough University, UK, and Hacettepe University, Turkey, by collecting simultaneous multimodal data from 13 participants (6 females and 7 males) by showing audio-visual stimuli. The total duration of all stimuli is 8 minutes and 50 seconds, which consist of short video clips selected from the web to elicit specific emotions. Between each video clip, in order to let the participants have a rest, a 20-second grey screen was showed. Although it is anticipated that each video clip elicits a distinct emotional state and thus can determine the label of the resulting emotion, in reality the same content might trigger differing emotions for different participants. Therefore, after each session, the participants were additionally asked to label the clips with the felt emotional state while watching them. Three different emotions were resulted from labelling: "sad", "neutral" and "happy". The facial expressions of the participants were captured using a webcam at a resolution of 640x480 and at 30 fps. Participants’ EEG data was captured using an ENOBIO 8-channels wireless EEG device, which has a temporal resolution of 500 Hz. We filtered EEG data for the frequency range [0, 75Hz] and applied baseline subtraction for each window. As for the peripheral physiological data, an EMPATICA E4 Wristband, powered by Bluetooth, was used to record participants’ GSR.<br>This multimodal emotion database is produced and should be used for research purposes only.<br>For any questions related to the data contained in this database, contact Dr Yucel Cimtay ([e-mail])拉夫堡大学多模态情感数据库-2（Loughborough University Multimodal Emotion Database-2，简称LUMED-2）是由英国拉夫堡大学与土耳其哈塞特佩大学的研究者构建的新型多模态情感数据集。该数据集通过向13名参与者（6名女性、7名男性）呈现视听刺激素材，同步采集其多模态生理与行为数据。 所有刺激素材总时长为8分50秒，均为从网络选取的短视频片段，用于诱发特定情感。每段短视频播放完毕后，会呈现20秒的灰屏以让参与者获得休息。 尽管预期每段短视频可诱发明确的情绪状态，从而直接确定对应情感标签，但实际中相同素材可能令不同参与者产生不同的情感体验。因此在每个实验环节结束后，研究者会额外要求参与者对观看过的片段标注自身实际感受到的情绪状态。最终通过标注得到三种情感类别：“悲伤（sad）”、“中性（neutral）”与“快乐（happy）”。 参与者的面部表情通过网络摄像头采集，采集分辨率为640x480，帧率为30 fps。参与者的脑电图（Electroencephalogram, EEG）数据通过ENOBIO 8通道无线脑电设备采集，该设备的时间分辨率为500 Hz。随后对脑电数据进行0~75 Hz频段滤波，并对每个数据窗口进行基线校正。 外周生理数据采集采用蓝牙供电的EMPATICA E4腕带，用于记录参与者的皮肤电反应（Galvanic Skin Response, GSR）。 本多模态情感数据库仅可用于科研用途。 若有关于本数据库中数据的相关疑问，请联系Yucel Cimtay博士（邮箱：[e-mail]）
