Most of the existing stress assessment frameworks rely on physiological signals measurements (EEG, ECG, GSR, ST, etc.), which involve direct physical contact with the patient in a medical setup. Present technologies rely on capturing moods and emotions through remote devices (cameras), further processed by computer vision and machine learning techniques. The proposed work describes a method of automatic stress classification where stress information is modeled based on pupil diameter non-intrusive measurements, recorded by an eye tracking remote system. The signal extracted from the pupil Dataset has been processed using the Bag-Of-Words model, with a SVM classification and results have been compared to similar experiments in order to validate the applicability and consistency of the Bag-Of-Words model on stress assessment and classification.
