Modeling Gaze Mechanisms for Grounding in HRI

Abstract

Grounding is essential in human interaction and crucial for social robots collaborating with humans. Gaze plays versatile roles for establishing, maintaining and repairing the common ground. It is combined with parallel modalities and involved in several processes for behavior generation and recognition. We present a uniform modeling approach focusing on the multi-modal, parallel and bidirectional aspects of gaze and their interleaving with the dialog logic.
