Study of Non-Verbal Behavior in Conversational Agents

Abstract: This paper studies the non-verbal behavior of a conversational agent named Arthur. We propose the development of body movements for this agent, which interacts solely through voice commands, chat, and videos with facial animations. This research aims to analyze users' perceptions regarding the gestures performed by Arthur. This study was conducted with participants who agreed to interact directly or through video with the conversational agent. The main goal is to analyze whether including nonverbal movements alters users' perception so that they feel more comfortable watching the video or interacting in real-time.
