The Role of Body Postures in the Recognition of Emotions in Contextually Rich Scenarios

In this article the role of different categories of postures in the detection, recognition, and interpretation of emotion in contextually rich scenarios, including ironic items, is investigated. Animated scenarios are designed with 3D virtual agents in order to test 3 conditions: In the still condition, the narrative content was accompanied by emotional facial expressions without any body movements; in the idle condition, emotionally neutral body movements were introduced; and in the congruent condition, emotional body postures congruent with the character's facial expressions were displayed. Those conditions were examined by 27 subjects, and their impact on the viewers' attentional and emotional processes was assessed. The results highlight the importance of the contextual information to emotion recognition and irony interpretation. It is also shown that both idle and emotional postures improve the detection of emotional expressions. Moreover, emotional postures increase the perceived intensity of emotions and the realism of the animations.
