Year: 2025
Type: article
Abstract: Emotion recognition based on electroencephalography (EEG) has gained significant attention due to its potential applications in human–computer interaction, affective computing, and mental health assessment. This study presents a convolutional neural network-based approach to emotion valence prediction model development using 4-channel headband EEG data as well as its evaluation based on computer vision emotion valence recognition. We trained a model on the publicly available FACED and SEED datasets and tested it on a newly collected dataset recorded using a wearable BrainBit headband. The model’s performance is evaluated using both standard train–validation–test splitting and a leave-one-subject-out cross-validation strategy. Additionally, the model is evaluated on computer vision-based emotion recognition system to assess the reliability and consistency of EEG-based emotion prediction. Experimental results demonstrate that the CNN model achieves competitive accuracy in predicting emotion valence from EEG signals, despite the challenges posed by limited channel availability and individual variability. The findings show the usability of compact EEG devices for real-time emotion recognition and their potential integration into adaptive user interfaces and mental health applications.
