Psychophysiology investigates the causal relationship of physiological changes resulting from psychological states. There are significant challenges with machine learning-based momentary assessments of physiology due to varying data collection methods, physiological differences, data availability and the requirement for expertly annotated data. Advances in wearable technology have significantly increased the scale, sensitivity and accuracy of devices for recording physiological signals…

Introducing WESAD, a Multimodal Dataset for Wearable Stress and Affect Detection

This work introduces WESAD, a new publicly available dataset for wearable stress and affect detection that bridges the gap between previous lab studies on stress and emotions, by containing three different affective states (neutral, stress, amusement).

ECG Pattern Analysis for Emotion Detection

This work brings to the table the ECG signal and presents a thorough analysis of its psychological properties, differentiates for the first time between active and passive arousal, and advocates that there are higher chances of ECG reactivity to emotion when the induction method is active for the subject.

Recognizing Emotions Induced by Affective Sounds through Heart Rate Variability

This paper reports on how emotional states elicited by affective sounds can be effectively recognized by means of estimates of Autonomic Nervous System (ANS) dynamics. Specifically, emotional states

A novel scheme of emotion-specific multilevel dichotomous classification (EMDC) is developed and compared with direct multiclass classification using the pLDA, with improved recognition accuracy of 95 percent and 70 percent for subject-dependent and subject-independent classification, respectively.

DREAMER: A Database for Emotion Recognition Through EEG and ECG Signals From Wireless Low-cost Off-the-Shelf Devices

DREAMER, a multimodal database consisting of electroencephalogram (EEG) and ECG) signals recorded during affect elicitation by means of audio-visual stimuli, indicates the prospects of using low-cost devices for affect recognition applications.

DEAP: A Database for Emotion Analysis ;Using Physiological Signals

A multimodal data set for the analysis of human affective states was presented and a novel method for stimuli selection is proposed using retrieval by affective tags from the website, video highlight detection, and an online assessment tool.

A dataset of continuous affect annotations and physiological signals for emotion analysis

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.

Real-time mental stress detection technique using neural networks towards a wearable health monitor

A real-time stress detection technique is presented which utilizes only a photoplethysmogram (PPG) signal to achieve improved accuracy over multi-signal-based mental stress detection techniques and can be extended to develop a remote healthcare system using wearable sensors.

Automated Affective Computing Based on Bio-Signals Analysis and Deep Learning Approach

The developed DL model is able to classify the emotional state into four classes, derived from the linear combination of valence and arousal, with an overall accuracy of 70% outperforming the 66% accuracy reached by the RF model.
