By Margaret McRorie,Ian Sneddon,Gary McKeown,Elisabetta Bevacqua,Etienne de Sevin,Catherine Pelachaud
Issue Date:July 2012
pp. 311-322
Convincing conversational agents require a coherent set of behavioral responses that can be interpreted by a human observer as indicative of a personality. This paper discusses the continued development and subsequent evaluation of virtual agents based on ...
Expressive MPEG-4 Facial Animation Using Quadratic Deformation Models

This special issue presents five articles covering a variety of computer graphics and embodied-conversational-agent applications related to digital human faces.
Influences and Embodied Conversational Agents
Found in: Autonomous Agents and Multiagent Systems, International Joint Conference on
By Vincent Maya, Myriam Lamolle, Catherine Pelachaud
Issue Date:July 2004
pp. 1306-1307
We aim at creating an Embodied Conversational Agent (ECA) that would exhibit not only a consistent behavior with her personality and contextual environment factors but also that would be defined as an individual and not as a generic agent. The behavior of ...
Towards a Simulation of Conversations with Expressive Embodied Speakers and Listeners
Found in: Computer Animation and Social Agents, International Conference on
By Thomas Rist, Markus Schmitt, Catherine Pelachaud, Massimo Bilvi
Issue Date:May 2003
pp. 5
In this paper we present some results to model complex interactions among virtual characters that participate in negotiation dialogues as well as our work related to a gaze model that controls the eye behavior of several agents conversing with each other. ...
Formational Parameters and Adaptive Prototype Instantiation for MPEG-4 Compliant Gesture Synthesis
Found in: Computer Animation
By Björn Hartmann, Maurizio Mancini, Catherine Pelachaud
Issue Date:June 2002
pp. 111
This paper introduces Gesture Engine, an animation system that synthesizes human gesturing behaviors from augmented conversation transcripts using a database of high-level gesture definitions. An abstract scripting language to specify hand-arm gestures is ...
A multimodal fuzzy inference system using a continuous facial expression representation for emotion detection
Found in: Proceedings of the 14th ACM international conference on Multimodal interaction (ICMI '12)
By Catherine Pelachaud, Catherine Soladié, Hanan Salam, Nicolas Stoiber, Renaud Séguier
Issue Date:October 2012
pp. 493-500
This paper presents a multimodal fuzzy inference system for emotion detection. The system extracts and merges visual, acoustic and context relevant features. The experiments have been performed as part of the AVEC 2012 challenge. Facial expressions play an...
Towards a smiling ECA: studies on mimicry, timing and types of smiles
Found in: Proceedings of the 2nd international workshop on Social signal processing (SSPW '10)
By Catherine Pelachaud, Elisabetta Bevacqua, Ken Prepin, Magalie Ochs, Radoslaw Niewiadomski
Issue Date:October 2010
pp. 65-70
Smile is one of the most often used nonverbal signals. Depending on when, how and where it is displayed, it may convey various meanings. We believe that introducing the variety of smiles may improve the communicative skills of embodied conversational agent...
Multimodal expressive embodied conversational agents
