Usability Test Event
Summary
A usability test was
completed to gain feedback
and knowledge of a user’s
ability to complete a task
using the app prototype.
During the usability test,
participants were given a
task scenario and asked to
complete a set of tasks.

Methods
The task scenario included
the situation of being on a
road trip late at night with a
group of friends where
suddenly they encounter a tire
blow out. Since the user nor
any of their friends knew how
to change a tire, the tasks
were to open up the Nissan
car manual app and from the
home page find the “changing
tire” section.
Tasks & Scenarios
The testing environment was located
at TTU usability lab. Equipment used
included eye tracking devices that
monitored the participants activity as
they navigated the app. The Lookback
app was used to record the
participant's reaction and thought
process.

Usability Test
The test sessions were recorded using the
LookBack app and analyzed from feedback
given by the users to help improve certain
areas.
According to Jakob Nielsen, five participants
are needed to ensure accuracy of results.
However, due to time constraints of the
project, we only tested three participants.

Methods
Context of Test
We completed our usability testing on Thursday,
October 20, 2016. The participants used for our
research were chosen randomly.
Before the test session, each participants
completed a pre-survey about their demographic
and what they would like from their car manuals.
We had a total of 3 participants, 2 males and 1
female, which were between the ages of 16-35.
Each participant session
lasted about 5 minutes. The
facilitator explained the task
scenario and asked each
participant to complete a
given task using the app
using think-aloud protocol.
At the end of each session,
each participant completed a
series post-test questions
about their user experience
with the app including what
they liked about the app and
what could be improved in
the design and function.

Testing Event:
Results and Findings
● 100% of the participants said that the app
was useful.
● 100% of the participants said that they
believed that the app would be useful if they
had an actual flat tire.
● 100% of the participants said that is was
better than actually using their car manual.
● 100% of the participants said they would
recommend it to a friend.
● 66.7% of the participants felt that the app
would be better if it had more pictures.
● 33.3% of the participants felt that a video
option would be a nice feature to add.
● 66.7% of the participants said that the app
was great.

User Feedback
Improve User Interaction
Perhaps the most common recommendation to the
improvement of our app was to make the app more
interesting and engaging
Add Images
There were a few instructions which had no picture to indicate
which part of the tire was being worked on.
Instructions Not Clear
Sometimes, pictures did not adequately demonstrate how to
perform a certain task so instead it would be more helpful to
include a video
Text Too Small, Background Color Good
Larger text should also help make the app more readable. The
light gray background with black text makes the app easy to
read.

Recommendations/Conclusion
Our usability research and testing demonstrates that car owners prefer a
mobile app car manual over the traditional print manual. Such an app for
the car owner manual could also be integrated into car navigation
systems. This app would also be useful for car owners or rental
companies that own vehicles where the print owner manual is missing.
Our next steps are to make final revisions based on user feedback, re-test
with a second group of participants. Final recommendations to the client
will be made after secondary revisions and testing.
