The technology of embodied conversational agents invirtual worlds provides an attractive way to achievenatural and realistic human-computer interaction if theinteraction designs is handled sensitively.In view of this,we aim at building an embodied tour guide that is able toengage conversationally with system users about galleryexhibits, and capable of behaving according to socialnorms in terms of gesture and facial expression.Theresearch has focused on the attributeds of agent autonomyand believability, not truthfulness.To achieve agentautonomy, we present a three-layered architecturaldesign to ensure appropriate coupling between agent'sperception and action, and to hide the internalmechanism from users.We then work towards agentbelievability: we utilize the notion of schema to supportstructured and coherent verbal behaviors; carefulattention has also been paid to the design of non-verbalagent interactions that help to establish social facts withinthe virtual world.Our discussion focuses on how reasoning, planning and generation of the verbal andnon-verbal behaviors are performed using the schema-basedframework.Finally the agent-user interactions areillustrated with a case study.
