In this paper we describe our eye-tracking data collection and preliminary experiments concerning the relation between eyegazing and turn-taking in natural human-human conversations, and how these observations can be extended to multimodal human-machine interactions. We confirm the earlier findings that eye-gaze is important in coordinating turn-taking and information flow in dialogues, but note that in multiparty dialogues also head movement seems to pay a crucial role in signalling the person's intention to take, hold, or yield the turn.
