Abstract

In this paper, we present an experiment where two human subjects are given a team-building task to solve together with a robot. The setting requires that the speakers ' attention is partly directed towards objects on the table between them, as well as to each other, in order to coordinate turn-taking. The symmetrical setup allows us to compare human-human and human-robot turn-taking behaviour in the same interactional setting. The analysis centres around the interlocutors ’ attention (as measured by head pose) and gap length between turns, depending on the pragmatic function of the utterances.
