Abstract
In this paper, we develop the basis for a game theoretical analysis of everyday interaction, focusing on the construction of an intersubjective set of action choices. For this purpose, we refer to Schutz's studies of action choice and intersubjectivity, because previous studies demonstrated a similarity between his theory and game theory. Therefore, we showed that the hypergame, a framework that deals with the situation where each actor’s perception differs of misperceptions, lies, or secrets, can represent interaction conforming to Schutz's ideas. This suggests that the game theoretical approach is one effective way to clarify interaction order, especially where there is an asymmetry of perception among actors.
