An interactive whiteboard for immersive telecollaboration

Abstract

In this paper, we present CollaBoard, a collaboration system that gives a higher feeling of presence to the local auditory and to the persons on the remote site. By overlaying the remote life-sized video image atop the shared artifacts on the common whiteboard and by keeping the whiteboard's content editable at both sites, it creates a higher involvement of the remote partners into a collaborative teamwork. All deictic gestures of the remote user are shown in the right context with the shared artifacts on the common whiteboard and thus preserve their meaning. The paper describes the hardware setup, as well as the software implementation and the performed user studies with two identical interconnected system
