Seminar 2
Chapter
13 was mainly about how evaluation is done throughout the design process. Some
of the main points that the book was trying to get across was that evaluation
and design are not two discrete units but rather that they are closely integrated.
Some methods for evaluation of different product where also given like controlled
settings involving users and so forth. The most interesting idea or concept
was, in my opinion of course, usability testing. The reason for this is that
this method gives the designer or developer a higher degree of control over
what gets tested something that can be very useful if the project is limited on
time and/or money. One major drawback of usability testing as I see it is that
some design flaws can go unnoticed since the testing is just done on a specific
area and hence limits the participants greatly which results in a test that is
not “deep” enough.
Personally
I think that our group could definitely make use of usability testing since we
do have some areas we are not totally sure about in our design and after that
it would greatly aid us in the design process if we could get some evaluations
of the entire product, although the prototype is not quite ready for that as of
the writing of this text.
Chapter
15 focused on heuristic evaluation and Analytics. Basically this chapter wanted
to point out that the ones doing the evaluation does not have to future users,
but rather they could also be some experts in the field that thoroughly tested
any product or critique a design. The analytics part was about how one can use statistics
to improve existing designs by, for example checking what users look for the
most and how many “clicks” it takes them to find it and so on.
The
most interesting concept that was completely novel to me was this Fitts’ Law,
something that I recon our design has to use! Using Fitts’ Law will allow us to
be somewhat confident with our design in the aspects regarding user friendliness
to some degree. What is great is that we can do this without having to use time
and effort to evaluate where to put for example buttons and how much spacing to
have etc.
Question:
Why
is involving users seen as too expensive? If a product does not have users as
its main focus how can it hope to succeed?
