In usual game theory, it is normally assumed that "all the players see the same game", i.e., they are aware of each other’s strategies and preferences. This assumption is very strong for real life where differences in perception affecting the decision making process seem to be the rule rather the exception. In this paper, we present a hypergame approach as a analyze tool that allows us to analyze such differences in perceptions. In particular, we explain how agents can interact through a third party when they have different views and particularly misperceptions on others game. After that, we show how agents can take advantage of misperceptions. Finally we conclude and present some future work.
