Project Name: A Natural-Language Generator for Embodied, Lifelike Conversational Agents

Abbreviation: Angelica

Start date: March 5, 2003

End date: March 5, 2007

Project Description:

Embodied conversational agents are animated computer characters that interact with a user in a face-to-face dialogue, with the purpose of making human-computer interaction more like communication between humans. To make such agents lifelike, they should not only use speech but also display appropriate nonverbal behaviour. The ANGELICA project deals with the combined generation of language and nonverbal signals in information presentation by embodied agents. Based on an analysis of human speaker data, we will formulate a computational model that can decide which modality, or combination of modalities, to use for expressing a given piece of information. Our focus will be on nonverbal signals that are used to indicate an object (by pointing) or to express certain aspects of an object or action (by gesturing). We will also address the influence of these nonverbal signals on the accompanying verbal output. Evaluation and testing form an integral part of the project. The application domain for our research will be the generation of route descriptions, a presentation task in which nonverbal signals play a prominent role. The ANGELICA project is expected to provide an important contribution to research on language generation for embodied conversational agents, which is still a largely unexplored problem.

Project Duration and Funding:

ANGELICA is funded by the NWO (Netherlands Organisation for Scientific Research) in a programme for individual researchers, in this case, specifically, to promote women researchers to the post of assistant professor.
