Design of Interactive Paper Documents


Rough Guide


PaperProof


Paper-Digital Structural Mapping

 Dual document representation in digital and
physical document spaces


Print-n-Link
 Citations build the basis
for a scientific web of
publications

 Use digital services to
search / retrieve cited
publications

 Automatic authoring


Other iPaper Applications …

PaperWeb Natural History Museum

Lost Cosmonaut (Axel Vogelsang) iTable (Google Earth)


Different Types of Link Authoring
 Manual authoring of links
 Content publishing framework for Interactive Paper
 EdFest brochure – PDF and links generated from
publishing database
 Automatic authoring of links based on document
analysis (PDF)
 Print-n-Link system for scientific publications
 Collaborative authoring based on P2P link sharing

RSL Structural Links


RSL Structural Links …
 Structure over data
 e.g. regular document (chapters, sections, ...)
 reuse of resources  transclusion (Ted Nelson)
 context-dependant structures
 Structure over structures
 structural composition of data and substructures can
be combined


RSL Structural Links …
 Structure over links
 put different navigational links in relation to each other
 e.g. single structural link to define linear order over
set of links  trails and tours


Active Content
 Execute code (services) on the client and server side
