Paralogue: A remote conversation system using a hand avatar which postures are controlled with electrical muscle stimulation

In this paper, we propose a new method of communication with a remote partner. The system, which we call "Paralogue" (parasitic + dialogue), utilizes the user's arm and a hand as an avatar that represents the remote conversation partner. This method is realized by controlling the movement of the user's arm with electrical muscle stimulations(EMS) and making the user's arm behave as if the remote conversation partner were speaking to the user. Therefore, it is possible to add the physical presence of the remote conversation partner to the situation. This can also be a telepresence system using real human arms. However, unlike many telepresence systems, external actuators and large-sized devices are not required for this system and can be completed by only utilizing physical interaction. In this paper, we present its design and implementation.
