ミニマルな聞き手性を備えたマイク型ロブジェクト〈Whimbo〉の提案

抄録

The field of Human-Robot Interaction (HRI) has begun to consider “robjects”, interactive robotic artifacts the design of which is based on objects rather than living creatures. We build a microphone-shaped robject “Whimbo” that expresses the minimal hearership to a speaker and listens to a speaker’s one-sided speech. The minimal hearership does not use of verbal behavior, but is expressed through body movements, which are nonverbal behaviors. We believe that this minimal hearership allows users can disclose their concerns and frustrations, which are difficult to speak to a human. In this paper, we prepared three conditions of “Whimbo” with different expressions of the hearership as a robject listener and conducted the experiment to evaluate examinee’s impressions, for example, ease of speaking and interest in speaking.
