Tracking Deictic Gestures over Large Interactive Surfaces
In a collaborative environment, non-verbal communication elements carry important contents. These contents are partially or completely lost in remote collaboration. This paper presents a system to address this issue by tracking pointing gestures, the main non-verbal communication element prevalent in such meetings. The setup employs a touchscreen tabletop computer system for representing the visual content of the meeting, together with three motion trackers for tracking the pointing gestures.
