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.

4

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

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:

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.
