Abstract:
In Human Computer Interaction (HCI), acquisition of physiological signals for emotion recognition is done by emotion researches. Prior to this, one needs to identify the reliability of physiological responses. The aim of this study was to investigate the reliability of physiological responses induced by sadness and disgust using an experiment that was repeated 10 times. Twenty subjects participated in this experiment. For emotion induction, twenty different emotional stimuli were selected in a pilot experiment. Skin Conductance Level (SCL), Skin Conductance Response (SCR), and Heart Rate (HR) were measured before the presentation of stimuli as a baseline and during the presentation of the stimuli as emotional state. The results showed that physiological signals during emotional states for the 10 times the experiment was repeated were stable and reliable compared to the baseline. Our results suggest that physiological signals of sadness and disgust are reliable over time. This means that physiological signals are reliable and useful tools for emotion recognition. These results can be useful in developing an emotion theory, or profiling emotion-specific physiological responses, as well as establishing the basis for an emotion recognition system in HCI.
