Adams, R. 38 slides 3
Egocentric design for UA
The Ego of the designer
⇛ designed by me for me designed by me for other
“geeks” designed for many
“geeks” designed for users designed for consumers designed for all
Adams, R. 38 slides 4
Egocentric design for UA
The Ego of the user ⇛ designed for the
stereotype designed for the
profitable designed market
share designed for
inclusion designed for the
inclusive Information Society
Adams, R. 38 slides 5
Egocentric design for UA
The Ego of the system ⇛
designed by a programmer
designed by a systems engineer
designed by a usability expert
designed for accessibility expert
designed for customisation
designed for adaptation
designed for adaptivity

The Challenge of Diversity

Adams, R. 38 slides 9
Egocentric design for UA
Egocentric design;
the capability of interactive system designers and users to design and develop new systems or variants of existing systems that focus on meeting their requirements better.
Adams, R. 38 slides 10
Egocentric design for UA
This is a dynamically growing area of intense activity, driven by;
user pressure, European policy on e-inclusion
and the commercial need for increased
market share.
Adams, R. 38 slides 11
Egocentric design for UA
To understand the concept of "egocentric design" better, a number of supporting concepts are presented
Adams, R. 38 slides 12
Egocentric design for UA
1. assistive technology,
2. ubiquitous design,
3. pervasive computing,
4. the information appliance, 5. universal access,
Adams, R. 38 slides 13
Egocentric design for UA
6. Universal usability
7. design for all,
8. adaptable and adaptive technology,
9. ambient intelligence and
10.the invisible computer.
Adams, R. 38 slides 14

An attempt is made to pull these vital concepts together in order to consider the future of computing science in the emerging Information Society."

a list of cognitive factors is not enough
cognitive architecture needed
specify how functions work together
