5. There is a conflict of interest in the world of
software development because the people
who build it are also the people who design it.
If carpenters designed houses, they would
certainly be easier or more interesting to
build, but not necessarily better to live in. The
architect, besides being trained in the art of
what works and what doesn't, is an advocate
for the client, for the user.
Alan Cooper. About Face, 1995

16. Human-computer interaction
“a discipline concerned with the
design
evaluation and
implementation
of interactive computing systems
for human use and with the study
of major phenomena surrounding
them." [ACM] 16
18. Usability
The effectiveness, efficiency, and satisfaction
with which specified users achieve specified
goals in particular environments
This does not mean you have to create a “dry” design or something that is only good for novices
– it all depends on your goals

23. The economist – oct. 2004
To be truly successful, a
complex technology
needs to “disappear”
The real test is always
the mom test

24. You are not the user!
(if you are the developer)

25. Four Myths
Only experts create good designs
experts faster, simple and effective techniques anyone can apply
We can fix the user interface at the end
good design is more than just user interface
having right features, building those features right
Good design takes too long / costs too much
simple and effective techniques can reduce total development time & cost
(finds problems early on)
Good design is just cool graphics
graphics part of bigger picture of what to communicate & how

26. If the user does something
“wrong”, it is the fault of the
system designer!

27. “logical analysis is not a good way to
predict people's behavior (nor are focus
groups or surveys): observation is the
key”
“I caution that the time frame for
adoption of new technologies is measured
in decades, not the months everyone
would prefer”
Donald A. Norman
