Outline

Motivation

Integration of digital and printed

information

information granularity

information semantics

Architecture / information concepts for

Digitally Augmented Paper

Other aspects of cross-media

publishing




The Myth of the Paperless Office

For decades, people have predicted

the office of the future as a paperless

office

documents generated, published and

distributed electronically

documents read electronically

What has happened to this

imminent revolution?




Paper++

Enriching the use of

paper in everyday

settings

EU Project (Disappearing

Computer Programme)

Arjo Wiggins




Case Study

BBC Blue Planet series

television series

available on video/DVD

book

web site

fact files

quizzes

games

Open University course book and CD




Linking of Sections to Digital Resources

symbols as link

to video/CD

note timing

information to

locate parts of

video




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)




Paper++ Document Encoding

page number, x and y

positions

Use RFID tags (Radio

Frequency Identification)

for document identification

Use inductive ink to print

a grid of invisible position

information on paper

Information:

(DocID, pageNo, x, y)




Multi-Layered Active Areas

Linking of active areas to

resource files

Problems of Digital Information

Coarse granularity of digital material

Single-level linking

No information semantics

Solution

Introduce richer information concepts

into the information server (e.g. appli-

cation DB)




Linking to Application Objects

Other Aspects

Link authoring

Publisher: Authoring as an integrated output channel for cross-media publishing

User: authoring as an additional post-processing step

Link sharing and derived linking

Personalisation and customisation

Integration of emerging technologies

new forms of paper, printing technologies and reader devices
