The proposed postdoc is part of a research on motivational technologies that help people adopt new behaviors for a healthier lifestyle. More precisely, we consider the methods used in motivational interviews and we study how they can be transferred to computer systems for personalized recommendations based on the user motivational degree and performance. Our system consists of a embodied conversational agent (developed by a private company part of the project, see https://davi.ai/fr/) that aims at motivating users to maintain a good level of physical activity in their everyday life. As an example, we try to increase the feeling of self-efficacy by showing vicarious experiences adapted to the user's profile.
The goal of the postdoc is to design, conduct and analyze the results of several experiments in which elderly people interact with the embodied conversational agent that makes use of different strategies to motivate participants to having physical activity. The system relies on the participant's psychological profile and physical activity data to control the agent's behavior and build a relevant dialogue.
A first experiment will lead to study how motivational interviews with virtual agents can reinforce the feeling of self-efficacy for physical activity. A second, longitudinal experiment will study how the agent's characteristics and the succession of motivational interviews contribute to maintaining a high level of physical activity for the elderly.

Work Context

This postdoc is part of a French National Research Agency project that involves 5 research labs and one company. This research project, entitled COPAINS, aims at developing a system that helps the elderly to have physical activity, using persuasive and motivational technologies that include an embodied conversational agent, adaptation to the user's affective state, multimodal interaction, and computational models of cognition (planing and reasoning).

The host institution, LISN, is part of University Paris-Saclay, France. It regroups 300 researchers, postdoc and PhD students. The CPU team that conducts this project is composed of researchers in psychology and computer science.
