INTRODUCTION
• The Nissan Mobile App Car Manual serves as an aide to new Nissan
car owners. This application contains valuable and helpful
information for consumers to use when in search for a task or in
need of assistance.
• The Usability tests conducted for this project served as a research
method in order to produce feedback from non-biased consumers.
Our group conducted a recorded prototype test of the app using
the Lookback app. The recordings were taken in order to observe
our participants comments, reactions, and concerns while using
the car manual application.

SUMMARY
• The usability tests were conducted outside of the classroom.
• Each member of the group had the task of finding and
testing two participants.
• The Lookback app gave the group access to view the screen
on the app on the phone as the testers browsed through it. It
also recorded the voice and face, if the participants
permitted the camera recording, in order to provide audible
feedback directly from the participants.
5. 5
SUMMARY
• Incorrect swiping links to the
adjacent screen.
• Links were layered over one
another, causing commands to
interfere with each other.
• Lack of clarity on the button
commands found at the top of the
app’s screen.
• Not all links were operational.
• Inaccurate commands between
swiping and clicking to move to an
adjacent screen.
Issues found from test
participants included:

read/see

RECOMMENDATIONS
• Aside from asking users what they thought
of the app, we also asked them what they
thought we should change about the
app. Here are some of their suggestions:
• If there is an option to tap part of the diagram to be
taken to the instructions for that part, state it
explicitly.
• Make statements such as “tap to see image” bold for
emphasis.
• Make direct links for the representative contact
phone number and email.
• Replace some of the menu buttons with icons that
better represent what they do.
