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



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



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


BUT WHO IS IN CONTROL?


The Challenge of Diversity




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.



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.



To understand the concept of "egocentric design" better, a number of supporting concepts are presented



1. assistive technology,

2. ubiquitous design,

3. pervasive computing,

4. the information appliance, 5. universal access,



6. Universal usability

7. design for all,

8. adaptable and adaptive technology,

9. ambient intelligence and

10.the invisible computer.



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

develop solutions / skills



Recipe for egocentric design (1) modelling; users platforms tasks / functions contexts of use



Recipe for egocentric design (2) application of expertise; user psychology accessibility task analysis links between design and
