ABSTRACT
Unlike legacy video-conferencing, which connects two nodes each equipped with a camera, recent systems facilitating for video-mediated group communication deal simultaneously with a large number of video streams. This highlights the need for orchestration,, i.e. the intelligent selection of the most adequate camera views to be displayed on each screen. In this paper we present the initial results of a study that evaluates the effects of orchestration on communication within a specific context; that of two remote groups playing a collaborative board game. The results of the experiment indicate that automatic orchestration can provide improvements similar to the ones achieved when live video mixing is performed by human editors.

Improving video-mediated communication with orchestration
Video-mediated communication (VMC) has become a popular communication medium. However, research to date suggests that the inherent constraints of VMC impair effective and efficient communication and task performance. We propose that these negative ...
Impact of seating positions on group video communication
CSCW '08: Proceedings of the 2008 ACM conference on Computer supported cooperative workIn this study, we examine how changes in seating position across different sites affect video-mediated communication. We experimentally investigated the effects of altering seating positions on conversations in four-person group communication, two-by-...
