Testing Methods
(1) Eye-tracking
A eye tracker (Tobii pro) was used during the whole course of task session to catch participants’ eye movement data, which usually captures the fixations, scan path over time while they are doing a task on the website.
The advantages of using eye-tracking technique is that, in real time, we can see exactly what a user is looking at- or not looking at- when navigating your site. By eye tracking the user, we can immediately identify usability problems and intuitively understand how to fix them. Eye tracking reveal issues that are often easy to fix and that have a high impact on improving conversion rates and sales figures.
(2) Interviews and satisfaction rating
Followed by each task scenario, we interviewed participants about their experience and asked them for a satisfaction rating on their experience.
(3) System Usability Scale
At the final phase of the session, System Usability Scale (SUS) was used to measure the overall usability experience.
(4) Performance evaluation
During each task session, we also measured total amount of time on each task for each subject, their performance errors and completion rate.
(5) Auditory recording
We were recording the whole tasks process for the analysis.
Scenarios and tasks
For this particular project, we were testing the following areas:
• Initial impression with the web site
• Explore and find if there are any special offers at the moment
• Build and price a vehicle (for a specific model)
• Review build model and book a test drive
Testing environment
Prior to the real testing, our group members worked together to set up the experimental program, run the pilot trial, and review the data, ensuring the whole system would function well during the real testing.
The testing took place in a soundproof booth. Participant sit in front of the desktop, which has the Tobii eye-tracking system installed, and the eye tracker is attached to the lower bar of the screen. One group member acted as an interviewer sitting besides the participant.
During the whole testing session, the other two group members sit out side of the testing room, watching the monitor screen and taking notes.
