GIAnT: Visualizing Group Interaction at Large Wall Displays
summary
GIAnT is an open-source analysis toolkit that visualizes multiuser activity on large interactive walls using synchronized views: a novel timeline visualization (time vs. horizontal position with line width encoding distance from wall), a wall view (gaze heatmap + touch scatter), and a floor view (position heatmap and trajectories). It ingests marker-based tracking, gaze estimates and user-coded touches, lets analysts inspect minutes-to-hours at-a-glance, and is validated by replaying and explaining behaviors in a cooperative game study.
