Collaborative Interaction on Large Tabletop Displays

We present an integration of several interface metaphors and interface components that are designed to support users interacting on large tabletop displays. These techniques— RNT, Storage bins, Interface Currents, Sticky Boards, and Sticky Notes—help solving the orientation problem on hori- zontal displays, allow to organize content on the interface in a flexible manner, and provide users with ways to annotate their objects.
