Can users react toward an on-screen agent as if they are reacting toward a robotic agent?

Our former study showed that users tended not to react to an on-screen agent's invitation of a Shiritori game (a last and first game), but did to a robotic agent. Thus, the purpose of this study was to investigate the contributing factors that could make the users react toward an on-screen agent as if they were reacting toward a robotic agent. The results showed that the participants who first accepted the invitation of a robotic agent that was assigned an attractive character reacted toward the on-screen agents as if they were reacting to the robotic one.
