Abstract:Embodied Conversational Agents (ECAs) are becoming more and more believable.One aspect of believability deals with the generation of realistic nonverbal behaviors when performing a communicative act. The choice of nonverbal behavior to express should depend on the ECA’s identity as well as the context of the conversation. The main goal of this research is to investigate the influence culture has on the choice of nonverbal behavior. An information model will be developed which structures cultural information about communicative behavior. This model will be integrated into a behavior generation framework for ECAs. This framework then makes it possible to generate communicative nonverbal behaviors adapted to an ECA’s identity, cultural roots and contextual factors specifying the conversational setting. The generation of nonverbal behaviors is determined by the communicative functions that need to be performed. The framework has two phases which determine the nonverbal behavior. First a choice will be made what behavior to express when performing a communicative function. This choice will be made using a mapping table converting functions to behaviors. Second, styles can be added to the generated behavior. Styles give additional information about the frequency and expressivity of certain behaviors.
