Towards a computational model for first impressions generation

This paper presents a plan towards a computational model of first impressions generation and its integration in an embodied conversational agent (ECA). The goal is to endow an ECA with the ability to manage the impressions elicited in the user by adapting its behaviour in order to impact the interaction. Our approach starts from studying first impressions mechanisms in human-human interaction, with the goal of investigating whether the same processes occur in the interaction with a virtual agent. We present results obtained from the analysis of a corpus of natural human-human interactions, and our future steps intended to build the impression generation and the adaptation modules for the computational model of the agent.
