Information layout and interaction techniques on an augmented round table

Round tabletop display systems are currently being promoted, but the optimal ways to use these systems to display a large amount of information or how to interact with them have not been considered. This paper describes information presentation and interaction technique for a large number of files on a round tabletop display system. Three layouts are explored on our augmented table system: sequential layout, classification layout, and spiral layout. Users can search and find files by virtually rotating the circular display using a ”hands-on” technique.
