Mutual Adaptation of Mind Mappings between a Human and a Life-like Agent

Abstract

This paper describes a human-agent interaction in which auser and a life-like agent mutually acquire the other's mind mappingthrough a mutual mind reading game. In these several years, a lot ofstudies have been done on a lifelike agent such as a Micro Soft agent, an interface agent. Through development of various life-like agents, amind like emotion, processing load has been recognized to play animportant role in making them believable to a user. For establishingeffective and natural communication between an agent and a user, theyneed to read the other's mind from expressions and we call the mappingfrom expressions to mind states mind mapping. If an agent and auser don't obtain these mind mappings, they can not utilize behaviorswhich significantly depend on the other's mind. We formalize such mutualmind reading and propose a framework in which a user and a life-likeagent mutually acquire each other's mind mapping. In our framework, auser plays a mutual mind reading game with an agent and they graduallylearn to read the other's mind through the game. Eventually we fullyimplement our framework and make experiments to investigate itseffectiveness.
