Abstract

<p>Discussion capability is important for humans and robots. We have previously developed a discussion system where two robots showed a user discussions about topics with two main claims by using an argumentation structure. However, a method of developing discussion that changes the user's opinion and the effect of robots’ appearances were unclear. In this study, we investigate the effects of discussion development and robots' appearances on user’s understanding. Field experiments were conducted for one month in an exhibition. The results obtained from 2925 conversations suggest that showing interactions where the robot with the opposite stance of the user agreed with another robot with the same stance improved the user's understanding. It is also suggested that when small humanoid robots rather than android robots with the same stance disagreed with another robot with the opposite stance, the user increases the confidence of the opinion.</p>
