CATCH : Human-agent social collaboration(s) during collaborative tasks Co-advisors : Catherine Pelachaud (ISIR), Domitile Lourdeaux (UTC), Indira Thouvenin (UTC) The topic of the post-doc focuses on an interaction of a human user with one or more Embodied Conversational Agents to perform a collaborative manipulation task in a virtual environment. The interaction takes place through verbal and non-verbal communication as well as by the manipulation of objects in a virtual environment displayed in a CAVE. The main topic of the post-doc is the consideration of the social attitudes of the agents, at the decision-making level, their impact on the cognitive and nonverbal behavior of the human, and the quality of the interaction as perceived by the human. The originality of the post-doc is to give the human being a strong immersion in the collaboration (during a joint action resolution) with ACAs by the addition of non-verbal behaviors and by taking into account manipulation gesture of the human. A social attitude is a combination of spontaneous assessment of a situation and of strategic intentions (Scherer, 2005). Most computational models have integrated the first aspect by simulating the emotional expressions of agents. Few studies have looked at the impact of social attitudes on decision-making. However, previous works do not consider social attitudes in the resolution of collaborative tasks. The post-doc aims to attack several scientific challenges: Challenge 1: What are the important / essential determinants in social attitudes for collaborative work? Which social interactions to transpose in virtual reality? Challenge 2: How to operationalize these social attitudes in a decision-making engine to represent the non-verbal, verbal and decisional behaviors of embodied conversational agents? Challenge 3: What types of adaptive feedback on social attitudes will affect human's behavior in an immersive virtual environment? Challenge 4: How to define a metric to measure the impact of social attitudes in collaborative work in virtual reality?
