This paper outlines two very different approaches to using physical paper documents as natural input devices to computers. The DigitalDesk is a computer-enhanced desk that uses a video camera to detect and recognise paper documents, while Xerox's 'Intelligent Paper' is specially produced paper containing invisible marks that uniquely identify each sheet. Both allow the visible contents of the paper to be matched to a corresponding digital document. This, in turn, allows natural actions, such as

The paper describes the basic mechanisms used in the two approaches and looks briefly at some existing and potential applications. It then looks in more detail at a specific application area: allowing printed documents to act as natural interfaces to the additional information found in digital versions encoded according to the Text Encoding Initiative (TEI) guidelines.
