Emotion Recognition for Human Machine Interaction

Abstract

Emotion Recognition is the process of automatic recognition of human emotions using AI concepts; research have focused on facial expressions and the various techniques. These automatically recognize the emotions using face, speech, body gestures, physiological signals, and brain signals. Later studies have shown that physiological signals, mostly EEG signals, contribute to reflecting true human emotion. Amongst these modalities, EEG technique has been proven to be the best for automatic recognition of human emotions using their linear, nonlinear, and frequency domain features.
