The main elements of the system design are a 3D representation of each space and a multi-display physical setup. The 3D image-based representation of a space is composed of an aggregate of live video feeds acquired from multiple viewpoints and rendered in a graphical visualization resembling a 3D collage. Its navigation controls allow users to transition among the remote views, while maintaining a sense of how the images relate in 3D space. Additionally, the system uses a configurable set of displays to portray always-on visual connections with a remote site integrated into the local physical environment. The evaluation investigates to what extent the system improves users' understanding of the layout of a remote space.","abstract_html":"uCom enables remote users to be visually aware of each other using "spatial displays" - live views of a remote space assembled according to an estimate of the remote space's layout.
