  • Patent number: 9917866
    Abstract: A technology for arrangement of interactive content on a large format display is disclosed. A heuristic determines content most likely to be interacted with by a user and rearranges content on the large format display to be closest to the user. For example, a window that was most recently interacted with can be arranged to be closest to a coordinate on the large format display that is closest to a user. Additionally, a display having a substantially “L-shaped” configuration allows for display of collaborative materials and video of remote participants simultaneously, which provides for a more natural interaction for a meeting participant interacting with the collaborative materials.
