Requirements and Building Blocks for Sociable Embodied Agents [chapter]

Stefan Kopp, Kirsten Bergmann, Hendrik Buschmeier, Amir Sadeghipour
2009 Lecture Notes in Computer Science  
To be sociable, embodied interactive agents like virtual characters or humanoid robots need to be able to engage in mutual coordination of behaviors, beliefs, and relationships with their human interlocutors  ...  We present work on probabilistic models for these three requirements with a focus on gestural behavior.  ...  Acknowledgements This research is supported by the Deutsche Forschungsgemeinschaft (DFG) in the Collaborative Research Center 673 "Alignment in Communication" and the Center of Excellence in "Cognitive  ...

Design of a Knowledge-Based Agent as a Social Companion

Leo Wanner, Elisabeth André, Josep Blat, Stamatia Dasiopoulou, Mireia Farrús, Thiago Fraga, Eleni Kamateri, Florian Lingenfelser, Gerard Llorach, Oriol Martínez, Georgios Meditskos, Simon Mille (+8 others)
2017 Procedia Computer Science  
We present work in progress on an intelligent embodied conversation agent that is supposed to act as a social companion with linguistic and emotional competence in the context of basic and health care.  ...  The core of the agent is an ontology-based knowledge model that supports flexible reasoning-driven conversation planning strategies.  ...  Intelligent conversation agents could help in that they could converse, entertain, coach, etc.  ...

THE ROLE OF GESTURE IN DOCUMENT EXPLANATION BY EMBODIED CONVERSATIONAL AGENTS

TIMOTHY BICKMORE, LAURA PFEIFER, LANGXUAN YIN
2008 International Journal of Semantic Computing (IJSC)  
We describe a preliminary computational model of document explanation by an embodied conversational agent, in which appropriate form and location of hand gestures are used by the agent in explaining a  ...  We find that hand gestures, and in particular deictic gestures by the professional at various parts of the document play a major role in explanations of documents with clients in face-to-face settings.  ...  Acknowledgments Thanks to Francisco Crespo and Thomas Brown for their assistance in conducting the evaluation study, to Mary Goodwin for being our expert in the second empirical study, and to our collaborators  ...

Giving interaction a hand

Stefan Kopp
2013 Proceedings of the 15th ACM on International conference on multimodal interaction - ICMI '13  
In this talk I will review approaches and methods applied to this problem and I will argue that such models need to (and can) based on a deeper understanding of what shapes co-speech gesturing in a particular  ...  How can we develop computational models for processing and generating natural speech-gesture behavior, in a flexible, fast and adaptive manner similar to humans?  ...  Another caveat is that gesture processing has been treated detached from approaches to generating speech and gesture in embodied agents, which has received continued research up to present.  ...

Harré and Merleau-Ponty: beyond the absent moving body in embodied social theory

CHARLES R. VARELA
1994 Journal for the Theory of Social Behaviour  
People are personal agents, and while enabled by their natural being, they are empowered by their social being to engage in the conversational practices of their local culture.  ...  This is a practice whereby any such conversation is performatively grounded in (and conventionally, a structuring of) a suitable gestural region of the body.  ...
