Abstract
Our new meeting room, the MR Square, was built as a testing ground of a variety of multimedia user interfaces and applications. The MR Square features mixed-reality technologies such as wide-area trackers and tens of head mount displays, as well as one 200-inch and two 150-inch screens. Participants sit and collaborate in fully wired, retractable seats. The MR Square illustrates how state of the art multimedia technologies can be incorporated into a meeting room.
