A dataset of continuous affect annotations and physiological signals for emotion analysis
AbstractFrom a computational viewpoint, emotions continue to be intriguingly hard to understand. In research, a direct and real time inspection in realistic settings is not possible. Discrete, indirect, post hoc recordings are therefore the norm. As a result, proper emotion assessment remains a problematic issue. The Continuously Annotated Signals of Emotion (CASE) dataset provides a solution as it focusses on real time continuous annotation of emotions, as experienced by the participants, while watching various videos. For this purpose, a novel, intuitive joystick based annotation interface was developed, that allowed for simultaneous reporting of valence and arousal, that are instead often annotated independently. In parallel, eight high quality, synchronized physiological recordings (1000 Hz, 16 bit ADC) were obtained from ECG, BVP, EMG (3x) GSR (or EDA) respiration and skin temperature sensors. The dataset consists of the physiological and annotation data from 30 participants, 15 male and 15 female, who watched several validated video stimuli. The validity of the emotion induction, as exemplified by the annotation and physiological data, is also presented.Measurement(s)electrocardiogram data respiration trait blood flow trait electrodermal activity measurement temperature muscle electrophysiology traitTechnology Type(s)electrocardiography Hall effect measurement system photoplethysmography Galvanic Skin Response skin temperature sensor electromyographyFactor Type(s)sex ageSample Characteristic OrganismHomo sapiens Machine accessible metadata file describing the reported data: https:/doi.org/10.6084/m9.figshare.9891446
