My research interests revolve around Human(Centred)-Computer Interaction with a strong emphasis on Embodied Conversational Agents (in particular their nonverbal expressivity) and Video Games.

Some projects:

ANR VirtuAlz

This project's objective is to develop of an innovative pedagogical software for healthcare professionals to train them on how to handle daily interactions with Alzheimer patients. Within this project, I co-supervise Amine Benamara's PhD thesis on the elaboration of a computational pathological model of emotions for a virtual patient.

PADME

This project's objective is to investigate how to take into account a user personnality to adapt interactions within a mobile application aimed at promoting physical activities. This project is the PhD thesis of David Rei, whom I co-supervise.


ANR COPAINS

This project's objective is to develop a software assistant able to influence positively the motivation of users towards physical activities for health improvement. Within this project, I investigate the effect of motivational interviewing techniques and principles on a user's self-efficacy when applied in a human-computer interaction.

MIMETIC

This project's objective is to create a tangible interactive device aimed at training children with ASD to perform joint-actions. Within this project, I worked on the tracking of the tangible objects and on the visualization of the children's activities with the system.

ImCasting

This project's objective is to investigate the development of an immersive game environment designed to support the interactive training of motions for Embodied Conversational Agents. Within this project, I co-supervised Miriam Punzi's Master thesis who built and evaluated the first version of the system.
