Previous research show that the remote conversations have a difficulty on showing the presence or attention to the other interlocutors, especially in the situation where the majority of interlocutor share the same place and one or a few interlocutor participate from difference place. This paper proposed "Parappa", a remote video conversation system, for those unbalanced condition by utilizing both physical and virtual approaches to share the nonverbal behaviors of remotely-participating interlocutor. The proposed system is constructed with a rotatable screen which projects the life-size avatar of remote interlocutor.
