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.This multimodal emotion database is produced and should be used for research purposes only.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, 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，同步采集多模态数据。所有刺激素材总时长为8分50秒，素材均为从网络遴选的短视频片段，用于诱发特定情感。每个视频片段之间会展示20秒的灰色画面，以供参与者休息。尽管预设每个视频片段可诱发独特的情感状态，进而可直接生成对应情感标签，但实际场景中，同一素材可能会引发不同参与者产生差异化的情感体验。因此，在每一轮实验结束后，参与者需额外标注观看片段时实际感受到的情感状态。最终通过标注得到三类情感："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，分辨率为640×480，帧率为30帧每秒（frames per second, fps）。参与者的脑电图（Electroencephalogram, EEG）数据通过ENOBIO 8通道无线脑电图设备采集，该设备的时间分辨率为500Hz。我们对脑电图数据进行了0至75Hz的频域滤波，并对每个数据窗口执行基线减法处理。外周生理数据方面，采用蓝牙供电的EMPATICA E4腕带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。若对本数据库包含的数据存在任何疑问，请联系Yucel Cimtay博士（邮箱：[e-mail]）
