Domain-Oriented Conversation with H. C. Andersen
This paper describes the first running prototype of a system for domain-oriented spoken conversation with life-like animated fairy tale author Hans Christian Andersen. Following a brief description of the system architecture, we present our approach to the highly interrelated issues of making Andersen life-like, capable of domain-oriented conversation, and affective. The paper concludes with a brief report on the recently completed first user test

ANGELICA: choice of output modality in an embodied agent
The ANGELICA project addresses the problem of modality choice in information presentation by embodied, human-like agents. The output modalities available to such agents include both language and various nonverba l signals such as pointing and gesturing. For each piece of information to be presented by the agent it must be decided whether it should be expressed using language, a nonverbal signal, or both. In the ANGELICA project a model of the different factors inf luencing this choice will be developed and integrated in a natural language generation system. The application domain is the presentation of route descriptions by an embodied agent in a 3D environment. Evaluation and testing form an integral part of the pr oject. In particular, we will investigate the effect of different modality choices on the effectiveness and naturalness of the generated presentations and on the user's perception of the agent's personality
