Color stimuli; Global Occurrence Matrix (GOM); Co-Occurrence Matrix (COM); valence; emotions; HRV.
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 Co- Occurrence 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.
