Abstract
The study reported in the paper focused on applying a set of affective body gestures extracted from the Geneva Multimodal Emotion Portrayals (GEMEP) dataset to two pedagogical animated agents in an online lecture context and studying the effects of those gestures on subjects’ perception of the agents’ emotions. 131 participants completed an online survey where they watched different animations featuring a female and a male animated agent expressing six emotions (anger, joy, sadness, disgust, fear, and surprise) while delivering a lecture segment. After watching the animations, subjects were asked to identify the agents’ emotions. Findings showed that only one expression of the angry emotion by the female agent was recognized with an acceptable level of accuracy (recognition rate >75%), while the remaining emotions showed low recognition rates ranging from 1.5% to 64%. A mapping of the results on Russel’s Circumplex model of emotion showed that participants’ identification of levels of emotion arousal and valence was slightly more accurate than recognition of emotion quality but still low (recognition rates <75% for 5 out of 6 emotions). Results suggest that hand and arm gestures alone are not sufficient for conveying the agent’s emotion type and the levels of emotion valence and arousal.
