Presentation Transcript

  1. Main lab. representatives • UH : L. Cañamero, D. Polani, R. te Boekhorst • CNRS: J. Nadel, S. Dubal, P. Fossati • U. Cergy Pontoise: P. Gaussier, P. Andry,… • EPFL : A. Billard, S. Calinon • Univ. Portsmouth: K. Bard, S. Vick • ICCS: S. Kollias, K. Karpouzis, A. Raouzaiou • ER: H. Lund • Aldebaran: B. Maisonnier, F. Bardinet

  2. Interdisciplinary work J. Nadel (humans), K. Bard (primates)

  3. Recent humanoid robots (G. Cheng ATR) Cog (R. Brooks MIT) Infanoid(I. KosimaNICT) (see also Y. Kunioshy works, G. Metta ICub…)

  4. How to ground it?

  5. Limitations in imitation systems: • No synchronisation capabilities between agents • Need of an explicit reward or adhoc mechanism to decide if given sequence must be learned • Need of an explicit signal to specify the beginning and the end of the expriment

  6. Imitation and social interactions

  7. Double function of emotions • Meta control (or second order controller) • Communication tool (in a single system!) => Capability to predict the rhythm of the exchange can be used as an internal reward

  8. First example:Learning to recognize facial expressions

  9. Development of facial expression recognition [Boucenna07,08] Videos on: www.etis.ensea.fr/~neurocyber/Videos/ Importance of the empathy Humans do resonate to simple robot heads [Nadel06]

  10. Emotional resonace torobot head Which are the minimal conditions for human resonance? [J. Nadel Team]

  11. [Dubal, Nade]

  12. Second example:using emotional signals for behavior modulation(learning…)

  13. Affective Bonds

  14. Implications for robotics

  15. Emotional value of interactions • Emotional resonance or contagion (bootstrap empathy) • Capability to predict the rhythm of the interaction (associated to a positive reward for ex.) • Imitation games (sharing emotions?)

  16. Rhythm prediction : positive reinforcement Incapability to predict the rhythm: negative reinforcement building of agentivity could be a consequence of first imitations not a prerequisite (developmental perspective) Toward bidirectional interactions
