In recent years, there has been agreement regarding the notion of involving emotions in HRI. On-line system, that recognized emotional state of the user and respond on it, could benefit effectiveness of HRI. Emotional interaction is the multi-model system that consists of the face, voice/speech expression of emotion and, newly emerging aspect, BEE, which is the subject of the presented study. Our off-line vision-based recognition system recognizes BEE with relatively high recognition rate, taking as input still photos of subjects, picturing basic emotions (Anger, Fear, Sadness, Joy). Based on this algorithm an on-line system, for recognition of BEE and for expression bodily emotional states of the robot, could be developed. Then I will present the study described how BEE are perceived and interpreted. The eye movements of human subjects were recorded while they were observing and recognizing photographs of static body postures expressing basic emotions. We were interested in determining recognition accuracy, response times and eye fixation patterns. For the study human arm movement under influence of basic emotions we selected as of periodic movement the drawing of an ellipse. Both, geometrical and kinematical characteristics of movement have been analyzed, and the correlation between those characteristics (by power -laws) has been evaluated and shown that most of all characteristics are influenced by emotions. Summarizing the talk I will discuss how the presented studies may be applied in HRI.
