WHY ON PAPER? The start of the chain is promising:

Content creation is done electronically

Indexing and searching is done electronically

(bulk) transport is done electronically

But then things go wrong.

Books and newspapers are printed

Personal content is printed

We read most of it on paper!

WHY??

Readers: Ease of use, readability, history Publishers: Copyright

Distributors & Printers: Livelihood

Cycle times are much faster in theelectronic cycle

Scientific, business

Significant cost reduction can be reached

Final part of distribution chain

Printing cost

Easy access to large library

Yet, there are many opportunities

SO WHY NOT YET?` Lack of a useable e-reader

Most reading devices use LCDs, which use backlights

x High power, hence low battery life

x Fatigue due to screen flicker

Most reading devices are small.

x Difficult to read

x Can not maintain original content layout

If not, they are heavy.

x Webtablets, laptop computers

` An astonishing number of different e-reading devices has been constructed.

` None really work(ed)!! (in the broadest sense..)

` Why not? Size / weight Battery life Low brightness / flicker Bad DRMsystem Lack of content Wrong style..? Filling a need that isnt there.

` So: Combinations of technical and marketing errors

` End of e-readers? The technology keeps evolving.

Historic trials and errors

REQUIREMENTSFROMTHESE GROUPS Requirements

Ease of use (understandable for everyone)

Readability (clear, bright text, no fatigue)

Actuality (Easy, automatic update)

Portability (lightweight, thin. Small?)

Pitfalls:

The competition is PAPER, not a laptop computer..

People have no frame of reference to what the device actually DOES
