Based on psychology literature on human emotions and the results of previous pilot experiment on emotional static body postures, we have explored the human perceptions of social behavioural and visual believability of a virtual character interacting with human users. The experiment specifically address the issues whether nonverbal expression and feedback from body movement effects users’ feeling, performance and judgments when interact with expressive virtual character. Subjects were examined across three experimental conditions that are detected participants emotional gestures, judge virtual character emotional expressions and interactions between subjects and virtual character. The results indicate that our system could detect subjects’ body movement of natural and intuitive emotional expression. Level of believability for virtual character that expresses selected emotions is high (above 3.40 mean ranks). The results also showed people having more aware of the emotions and the level of believability were increased when interact with virtual character compare to one way communication.
