The Extended Window Metaphor

The Extended Window Metaphor is a novel tele-presence approach that extends the window metaphor by combining large high-resolution LCD walls with multi-camera 3D video. We propose to integrate an array of cameras into the bezels of the wall to support flexible camera placement for optimized video acquisition. The users’ 3D video representation combined with the high-resolution LCD wall provides local and remote users with a shared virtual space in an extended life-size window metaphor.

One of our central ideas is the integration of cameras directly into the LCD wall by utilizing the ”unused“ bezel space between individual display panels. Integrating cameras directly into the display wall provides us with a number of interesting new options. We are able to capture free-viewpoint 3D video with multiple cameras that are facing the user directly.
