  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.
