Describe a situation in software interfaces where differences in physical
characteristics cause usability problems. What could a designer do
to accommodate these differences?
From your experiences with software products, give three examples of how
cognitive characteristics can affect user satisfaction with a
You have been asked to survey users who are representative of the planned
target for a new software product, an automatic translation facility
that translates written text from Spanish to English or vice versa.
(a) If there are no existing software products of this type, how
can you find "representative users"? Describe what you would do.
(b) List five cognitive characteristics you would
want to include among your example users. (If it helps, imagine
that the planned software will do.)
Why is the process referred to as requirements "capture"?
List three reasonable user requirements for the automatic translation
For any one of the user requirements you just identified, define two
usability criteria that could be tested empirically.
What is the difference between a descriptive prototype, a visual
prototype, an interactive prototype, and a "Wizard of Oz" prototype?
For each, describe 1-2 featurs of the automatic translation
software that could be evaluated using that particular
class of prototype.
