ABSTRACT: While there have been dramatic increases in the use of digital technologies for the storage and processing of information, the affordances of paper have ensured its retention as a key information medium. Recent developments in digitally augmented paper provide the potential to embed active links within printed documents, thereby turning paper into an interactive medium. In this paper, we address the issues of information granularity and semantics that arise in integrating paper as a first-class interactive information medium in hypermedia systems and show that the information server is vital in realising the true potential of this vision. Further, we discuss the authoring issues of cross-media information environments and the forms of tools required to support the various categories of authoring activity.

  7. 7. Problems of Printed Information Coarse granularity of available links to digital media (symbols) sections of text linked to video/CD good to have finer units of granularity Missing link context in printed media impossible to resolve links back to printed paper (unidirectional linking) Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland

Paper++ Document Encoding Use inductive ink to print a grid of invisible position information on paper page number, x and y positions Use RFID tags (Radio Frequency Identification) for document identification Global Information Systems Group Department of Computer Science Information: ETH Zurich, Switzerland (DocID, pageNo, x, y)
