Why the study?
The study aimed to build a public immersive virtual reality database, collect brainwave signals with a low-cost wearable EEG headset during emotion induction, and evaluate machine learning classifiers for intra- and inter-subject emotion recognition.
A low-cost wearable EEG headset combined with VR stimuli and SVM classification achieved 85.01% accuracy in four-class emotion recognition.
