EMOTION RECOGNITION BASED ON UTILIZING OCCURRENCE SEQUENCE OF HEART RATE'S PHASE SPACE POINTS

摘要

In this paper, we have used the color stimuli to define the valence level of subjects by analyzing their heart rate variability (HRV). For this analysis, we have used the novel features, Global Occurrence Matrix (GOM) and Cooccurrence Matrix (COM), and try to distinguish two groups of positive and negative emotions. The results show that cold colors are associated with high valence level and hot colors are in relation with low valence level.
