Introduction/Summary

The Nissan Car Manual mobile app prototype was designed make

complex instructional information clear, visual, and more accessible to car owners, and assist in emergencies with more efficient communication.

Usability Test Plan

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.

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

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.

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.

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

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.
