Life-Like Characters– …, 2003

Embodied conversational agents provide a promising option for presenting information to users. This contribution revisits a number of past and ongoing systems with animated characters that have been developed at DFKI. While in all systems the purpose of using characters is to convey information to the user, there are significant variations in the style of presentation and the assumed conversational setting. The spectrum of systems include systems that feature a single, TV-style presentation agent, dialogue systems, as well as systems that deploy multiple interactive characters. We also provide a technical view on these systems and sketch the underlying system architectures of each sample system.

Abstract This paper explores the use of fast, simple computer vision techniques to add compelling visual capabilities to social user interfaces. Social interfaces involve the user in natural dialog with animated,“lifelike” characters. However, current systems employ spoken language as the only input modality. Used effectively, vision can greatly enhance the user's experience interacting with these characters. In addition, vision can provide key information to help manage the dialog and to aid the speech recognition process.

International Workshop on Information Presentation and Natural Multimodal Dialogue, 2001

1 Abstract This paper illustrates the architecture of a multimodal believable agent, provided with a personality and a social role, aiming at providing information to users engaging them in a natural conversation. To achieve this aim, we provide our agent with a mind, a dialogue manager and a body: a) the mind, according to the agent's personality, the events occuring and the user dialog move, triggers, if appropriate, an emotion; b) the dialog manager, according to an overall dialog goal and the corresponding plan to be pursued, selects the ...
