In the field of Cognitive Science and Linguistics, it is pointed out that the speakers Grounding process is an essential to build mutual understandings and establish common ground. In our laboratory we are examining what kind of cognitive mechanisms and the interactive process influence the success of grounding. We also analyze how speakers use their nonverbal information’s such as gaze behaviors along with verbal information. These research are carried out by conducting psychological experiments and computational modeling. On analyzing multimodal information, we focus on indicators such as eye-movements and facial expressions.
