Implementing three-party desktop videoconferencing

We describe the implementation and test of a novel three-party desktop videoconferencing system. To allow for gaze and workspace awareness between the participating partners a special quasi-spatial arrangement of cameras and graphical user interface elements is chosen. We informally tested the system setup with a usability evaluation presented at the end of this paper. Our prototypical solution is a customizable off-the-shelf, affordable way of supporting mutual awareness in three-party videoconferencing.
