This paper investigates how users respond to emotional expressions displayed by an embodied agent. In a between-subjects experiment (N = 50) an emotionally expressive agent (simulating the role of a nutritional coach) was perceived as significantly more likeable and caring than an unemotional version. Feedback from participants also revealed detailed insights into their perceptions of the agents and highlighted a strong preference for the emotionally expressive version. Design implications for embodied agents are discussed and future research areas identified.
