Contribution

It introduces a novel approach for measuring joint attention tailored for wall-sized displays in collaborative settings.

Findings

Effective measurement of joint attention using head gaze data

Insights into collaboration dynamics on large displays

Preliminary validation from user study data

Abstract

To understand and quantify the quality of mixed-presence collaboration around wall-sized displays, robust evaluation methodologies are needed, that are adapted for a room-sized experience and are not perceived as obtrusive. In this paper, we propose our approach for measuring joint attention based on head gaze data. We describe how it has been implemented for a user study on mixed presence collaboration with two wall-sized displays and report on the insights we gained so far from its implementation, with a preliminary focus on the data coming from one particular session.
