GRETA Team

Description, Members, Publications, Demos

We work on making human-computer interactions more emotion-oriented and social. We develop an interactive embodied conversational agent platform technology. Our methodology is based on the quality and property of humans’ communication. We are interested in improving communicative skills of virtual agents and learning about human behaviour and communication.

Our team is centered on research involving Greta, the embodied conversational agent. The agent is autonomous and expressive. Greta can express her emotional states and intentions through verbal and nonverbal behaviours, and be socially aware. She can endorse different roles, e.g. be a dialog companion, a storyteller, a virtual tutor, an actor in different games.

Greta is part of the SEMAINE platform where she is endowed with the capabilities to recognise emotional states, to process speech and to express verbal and nonverbal behaviours.

In our current projects we develop:

  • synchrony between user and agent or between several agents
  • conversational and listening behaviour (dialog systems, backchanneling, mimicry)
  • emotional and empathic skills of agents
  • expressive humanoid robot
  • social agent
  • multimodal expressive behaviours
  • expressive face and body animation
  • emotional agent in serious game
  • perception of mental states (appraisals, emotions)

We are involved in European projects: NoE SSPNet, FET-OPEN ILHAIRE, Reverie, FP7 ICT VERVE, TARDIS and national French projects: ANR MOCA , DGCIS Avatar 1:1, DGCIS EMMA, ANR GV-Lex, ANR IMMEMO, , ANIPEV and PlaySerious.

We were involved in European projects: CALLAS, SEMAINE, HUMAINE, and national French projects: ANR CECIL, ISCC Apogeste, ANR MyBlog3D, RIAM ACE, RIAM LABIAO, Web2.0 My Presenting Avatar.

Keywords: embodied conversational agent (ECA), emotion, affective computing, multimodal communicative behaviour, synchrony, backchannels, mimicry, humanoid robot, multimodal interfaces
