This paper presents an approach for tracking paper documents on the desk over time and automatically linking them to the corresponding electronic documents using an overhead video camera. We demonstrate our system in the context of two scenarios, paper tracking and photo sorting. In the paper tracking scenario, the system tracks changes in the stacks of printed documents and books on the desk and builds a complete representation of the spatial structure of the desktop. When users want to find a

The system also provides a remote desktop interface for directly browsing the physical desktop from a remote location. In the photo sorting scenario, users sort printed photographs into physical stacks on the desk. The system automatically recognizes the photographs and organizes the corresponding digital photographs into separate folders according to the physical arrangement. Our framework provides a way to unify the physical and electronic desktops without the need for a specialized physical infrastructure except for a video camera.
