Affective component used in this study was based on three
input channels: video capturing for facial expressions
analysis (with Logitech Internet camera and compatible
software solution), self-report based on PAD (Pleasure-
Arousal-Dominance) emotion representation model [22] and
physiological signals recording as a reference (skin
conductance, blood-volume pulse and respiration rate
recorded with ProComp Infiniti hardware coder together
with Biograph software).
