Research

Multi-agent system, Human-machine interaction, Emotional dialogue, adaptive execution, analysis of behavior, games.

Postdoc:

The postdoc work targets specifically the emotional dialogue model. It consists in taking into account emotions, personality and the experiment in the interaction between artificial agents and/or artificial agents and human agent.

This work regards DEEP project whose aim is to develop techniques and tools to allow the designers of adventure games to quickly define NPC (Non player character) with emotions, personality and able to take into account the evolution of the scenario during their dialogues with the human player.


PhD work:

Taking into account of the user's behavior in the interactive applications, which include the human user, appears obvious for the formation of a mechanism of fast decision-making and adapted to the situation. It consists in extracting conclusions relating to user's behavior and provides in a real time personal way adequate activities, keeping in mind the expert's advice. Within this framework, we have contributed to the problem of the adaptive execution by observation and analysis of behavior.

The first part of our work is about behavior analysis. We thus defined a formalism based on the observation of the user's behavior. It consists in the observation carried out on the explicit and implicit actions of user. The first one, recovering the user's actions carried out on : mouse, touch screen keyboard. The second one, concern facial expression.

The second part of our work is about execution control of the activities by taking into account of the user's behavior.We have defined a model based on the case-based reasoning that allows the generation of activities answering the description of the user's profile, his behavior and these needs. Our strategy of control consists in launching an episode of reasoning each time that a particular behavior is detected.

The last part of our work is devoted to the presentation of our system developed within the framework of the Autism Project. It is about a system proposing the educational games intended for children with autism. This system constituted a framework of application and validation of our contribution. This application framework reflects significant characteristics of user-adapted interactions according to the perceived behavior, behavior apprehended by various means (answers to the game and expressions facial). Thus, the system in question, based on the multi-agents paradigm, includes the knowledge of therapists, the children profiles and the dynamics of their interactions.

Teaching :

For 4 years I have taught various courses at the Institute of Technology and Department of Computer Science of La Rochelle University for Bachelor's degree and Master students. The main task consists in carried out courses, Tutorials, practical works, and to correct exams and evaluate projects. The courses that I have ensured are regrouped into 4 themes:
  • Network and computing system.
  • Algorithmic and oriented object programming.
  • Interaction and intelligent system.
  • Methodology and usage

Others:

  • Realization of two featurettes (2004 and 2005) within the framework of 5th and 6th festivals organized by the association of PhD students of La Rochelle University. Writing, shooting and editing.
  • Secretary of the association of PhD student of La Rochelle University (2004).
  • Sport (badminton, soccer, swimming)
