An Operational Model of Joint Attention - Timing of Gaze Patterns in Interactions between Humans and a Virtual Human

Abstract

Joint attention has been identified as a foundational skill in human-human interaction. If virtual humans are to engage in joint attention, they have to meet the expectations of their human interaction partner and provide interactional signals in a natural way. This requires operational models of joint attention with precise information on natural gaze timing. We substantiate our model of the joint attention process by studying human-agent interactions in immersive virtual reality and present results on the timing of referential gaze during the initiation of joint attention.
