Emotion recognition using EEG signals with relative power values and Bayesian network

Abstract: Many researchers use electroencephalograms (EEGs) to study brain activity in the context of seizures, epilepsy, and lie detection. It is desirable to eliminate EEG artifacts to improve signal collection. In this paper, we propose an emotion recognition system for human brain signals using EEG signals. We measure EEG signals relating to emotion, divide them into five frequency ranges on the basis of power spectrum density, and eliminate low frequencies from 0 to 4 Hz to eliminate EEG artifacts. The resulting ca… Show more

“…One approach to analysis and recognition of emotions is to directly assess the activity of the central nervous system, specifically brain electrical activity, and study the changes in this activity as the user experiences different emotional states. Several works exist that are related to emotion recognition from electroencephalogram (EEG) [7,14,10,2]. Furthermore, there are a number of experiments pointing to the fact that physiological activity is not an independent variable in autonomous nervous system patterns but reflects experienced emotional states with consistent correlates [1,17].…”

“…The electrical potentials related to emotion can be projected widely in an intricate pattern across the scalp, and can therefore overlap with potentials evoked by other activities. EEG has been applied for classification of emotions in various contexts [8], [43], [82], [88] and is progressively becoming a portable lightweight technology. Several commercially available EEG sets can be considered for affective gaming: OCZ Nia 1 , Neurosky Mindset 2 , Neurosky Mindwave 3 , Emotiv EPOC 4 .…”
