This study investigated what effect physical constraints have on the interpretation of demonstrative pronouns when a user navigates a robot. For this investigation, a robot navigation environment called Spondia-II was develope, and an experiment conducted. It is known that the interpretation of demonstrative pronouns requires information about not only the situation (or context) but also the speaker's viewpoint during a dialogue. The results of the experiment suggest that physical constraints do affect the user's viewpoint, especially when a user utters a demonstrative pronoun while navigating the robot. In actual fact, the user alters the use of demonstrative pronouns according to the change in the user's viewpoint. It is also suggested that the user and the robot share the same viewpoint during the physical interaction.
