Eye gaze and viewpoint in multimodal interaction management

© 2017 Walter de Gruyter GmbH, Berlin/Boston 2017. In this paper, we present an embodiment perspective on viewpoint by exploring the role of eye gaze in face-to-face conversation, in relation to and interaction with other expressive modalities. More specifically, we look into gaze patterns, as well as gaze synchronization with speech, as instruments in the negotiation of participant roles in interaction. In order to obtain fine-grained information on the different modalities under scrutiny, we used the InSight Interaction Corpus (Brône, Geert & Bert Oben. 2015. Insight Interaction: A multimodal and multifocal dialogue corpus. Language Resources and Evaluation 49, 195-214.). This multimodal video corpus consists of two- and three-party interactions (in Dutch), with head-mounted scene cameras and eye-trackers tracking all participants' visual behavior, providing a unique 'speaker-internal' perspective on the conversation. The analysis of interactional sequences from the corpus (dyads and triads) reveals specific patterns of gaze distribution related to the temporal organization of viewpoint in dialogue. Different dialogue acts typically display specific gaze events at crucial points in time, as, e.g., in the case of brief gaze aversion associated with turn-holding, and shared gaze between interlocutors at the critical point of turn-taking. In addition, the data show a strong correlation and temporal synchronization between eye gaze and speech in the realization of specific dialogue acts, as shown by means of a series of cross-recurrence analyses for specific turn-holding mechanisms (e.g., verbal fillers co-occurring with brief moments of gaze aversion).
