Implementing a Multiparty Support in a Tour Guide System with an Embodied Conversational Agent

In this project we aim to implement multiparty support in a Tour guide system with an Embodied Conversational Agent (ECA). We studied multiparty dialogue issues and adapted some of them to our system. As the outcome of the project, the first prototype of a tour guide system has been developed. The system can automatically detect presence of humans and invite them to a tour session. During the session, according to the number of users and their positions, ECA uses a gaze model implemented from conversational theory to address a specific user. ECA also reacts to decreased level of attention and tries to keep the interest in the session. Although conversational model in our system is rather simple, we find this work a first step for further system development in the ECA-human multiparty domain. Experiments with such systems can provide useful research studies in the field of interaction between ECA and humans.
