Sažetak
In recent years, computer-generated interactive virtual characters, called Embodied Conversational Agents (ECAs), are subjects of considerable ongoing research. Nevertheless, their conversational abilities are mediocre compared to real human behaviors. Among limitations, most of ECAs are incapable of participating in natural conversations in which the number of participants can change dynamically. In the ongoing work we investigate principles of integrating a multi-user support in an ECA system. We present experiments and implementation approach of a prototype system in which a tour guide ECA interacts with one or two users. The system combines different technologies to detect and address the system users and draw their attention. Experimental interaction with the system produces encouraging results. The system can address the user’ s appearance, departure, decreased level of interest and identify his conversational role.
