This paper presents a model that provides adaptive and evolutive interaction between a human and a virtual agent. After introducing the theoretical justifications, the aliveness metaphor and the notion of coupling are presented. Then, we propose a formalization of the model that relies on the temporal evolution of the coupling between participants and the existence of phases during the interaction. An example on a fitness exergame is provided and some illustrations show the behavior of the model during an interaction. A video complements this example.
