This document provides an introduction to a course on human-computer interaction. It discusses several reasons why students chose the course, including that it is interactive, practical, and teaches skills that will be useful for later work. It also lists some common interface problems students have encountered, such as issues with setting up accounts or finding information on websites. Finally, it introduces some of the key concepts in human-computer interaction, such as the importance of user-centered design and usability testing.

7. 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.

• download uit mail -> beveiligde map, overschrijving
• delijn.be
• toledo -> assignment indienen
• laserprinter -> r0x32 boodschap

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

18. 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

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

20. “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
