Towards computer-supported face-to-face knowledge sharing

Although a lot of systems provide co-located collaboration support, few existing technologies provide support for fluid knowledge sharing. To fluidly share our knowledge in co-located environments, each person's digital experience should be merged and presented on a collaborative display device such as a face-to-face tabletop display. For capturing concrete requirements for such face-to-face fluid knowledge sharing, we built a prototype system that presents merged multi-users' Web browsing histories on a tabletop display. We experimented with our prototype in an exhibition and collected over 100 filled questionnaires and informal observations.
