People have had trouble
with using a photocopier because of its complexity. Users
know what they want, but there are so many options that users
sometimes feel overwhelmed. Oftentimes, users do not know
how to accomplish the task they want because the interface
is too confusing. So I took an approach that would present
users with only the most common options and put the other
options in a separate tab.
The first step was to paper
prototype my design. I printed out my design and pasted them
onto notecards. I created a task that would be realistic and
made sure that it covered the interface aspects I was intereted
in testing. Then, I tested my design on users employing a
Think Aloud method. Any critical incidents were documented
in Usability Aspect Reports.
The next step was to create
a design in Visual Basic that took into account the first
round of user testing. After the Visual Basic prototype was
complete, I went through a second round of user testing employing
the same Think Aloud technique and task. Again, the critical
incidents were put into Usability Aspect Reports.
The final step was to iterate
on the Visual Basic program using the user testing data and
then perform a final round of user testing. This time for
the user testing, I still used a Think Aloud method, but I
changed the task to cover more aspects of the interface that
I wanted to test. I again reported the critical incidents
in Usability Aspect Reports.
