7. Intro What is a user interface? Why do we care about design?
We see this all the time.
What’s good about the design of this error box?
The user knows there is an error
What’s poor about the design of this error box?
Not enough information
No way to resolve the problem (instructions or contact info)

8. Why study human use of computer systems?
Business view:
to use humans more productively/effectively
the human costs now far outweigh hardware and software costs
Personal view:
people view computers as appliances, and want it to perform as one
Marketplace view:
everyday people using computers
now expect “easy to use system”
not tolerant of poorly designed systems
little vendor control of training
heterogeneous group
if product is hard to use, people will seek other products
eg Mac vs IBM (Microsoft Windows)

9. Why study human use of computer systems?
The system view:
complex human
complex computer
complex interface between the two
The human factors view:
humans have necessary limitations
errors are costly in terms of
loss of time
loss of money
loss of lives in critical systems
loss of morale
design can cope with such limitations!
