遠隔存在感を高めるアバターの挙動設計の研究

個性を反映した挙動設計による遠隔人物存在感の向上の試み

A problem in hybrid communication is that the conversation proceeds only with the face-to-face participants due to the lack of the presence of remote participants. In our research, we aimed to improve the presence of remote participants by designing the motion of the avatar robot. We hypothesize that the richness of model evidence for remote participant cognition corresponds to the presence of remote participants. We analyzed the elements of the presence of remote participants and focused on the state of "imposing" as model evidence of the presence of remote participants. We have not found any research so far that mathematically discusses the state of being “imposing” and the behaviors related to that state. Therefore, we mathematically modeled the behavior of imposing speakers by active inference. In our model, the state of being "imposing" corresponds to precision of action policy in active inference. Based on the mathematical model, we designed the behavior of the avatar robot that changes according to the precision. We confirmed the possibility of improving the presence of remote participants by designing the motion of the avatar robot with active inference.
