This paper examines how eye gaze activities are different in between human-human and human-robot conversations in second language (L2). The results show that the mainly-gazed-at listener gazes more at the speaker and he/she takes more often a floor in L2 conversations than in L1 conversations, whereas the speaker’s eye gaze activity is almost the same in both conversations. The result shows that there is a significant positive correlation between the mainly-gazed-at listener’s gazing ratio and the ratios of mainly-gazed-at listener taking a floor. Comparative analyses of eye gaze activities between human-human and human-robot conversations are also conducted. The results show that the listener gazes more at the speaker in human-robot conversations than in human-human conversations, whereas the robots do not provide the nonverbal information related to the contents of the utterances. These results may show that listeners gaze more at the speaker to show their intention to take a floor in both human-human and human-robot conversations.
