Abstract:
We have made noticeable progress in developing robots and virtual agents; human-like robots and agents are closer than ever to becoming a reality. We want to develop an embodied conversational agent that is regarded as a social partner, not just multimodal interface. However, the mental stance of people when they interact with agents is usually different from when they interact with humans. Therefore, in some cases, it is difficult for people to speculate on an agent’s emotion and it is also difficult for an agent to persuade people. To solve this problem, we focused on "intentional stance". Intentional stance is a mental state in which we think that an interaction partner has intention. We hypothesized that agents could induce the intentional stance by performing goal-oriented actions in human-agent interaction. To investigate the effect of induction of intentional stance, we made two agents: a "trial-and-error agent" that performed goal-oriented actions using multimodal behavior and a "text display agent" that displayed its behavioral intention via text. We conducted an experiment in which two participants played customized tag in virtual reality with one of the agents. The results showed that participants continuously tried to communicate with the trial-and-error agent, which did not respond to the participant's actions except when necessary for performing the task. We found that the participants felt that the agent using multimodal nonverbal behavior was more goal-oriented, more intelligent and understood their intentions more than the agent that displayed text above its head. Thus, we were able to induce the intentional stance by presenting a trial-and-error process using multimodal behavior.
