Mutual Learning of Mind Reading between a Human and a Life-like Agent

Abstract. This paper describes a human-agent interaction in which a user and a life-like agent mutually acquire the other’s mind mapping through a mutual mind reading game. In these several years, a lot of studies have been done on a life-like agent such a Micro Soft agent, an interface agent. Through development of various life-like agents, a mind like emotion, processing load has been recognized to play an important role in making them believable to a user. For establishing effective and natural communication between a agent and a user, they need to read the other’s mind from expressions and we call the mapping from expressions to mind states mind mapping. If an agent and a user don’t obtain these mind mappings, they can not utilize behaviors which significantly depend on the other’s mind. We formalize such mutual mind reading and propose a framework in which a user and a life-like agent mutually acquire mind mappings each other. In our framework, a user plays a mutual mind reading game with an agent and they gradually learn to read the other’s mind through the game. Eventually we fully implement our framework and make experiments to investigate its effectiveness.
