We helped Svensk Adressändring with an extensive UX test. The test was performed at a central location using eye tracking enabled monitors and in-depth interviews with respondents.
The best insights from usability tests are gained when users do not have to explain what they are doing (Think-aloud) but rather execute the test in silence and in their own tempo.
To allow this we used a method called Eye Tracking enabled Retrospective Think Aloud.
After the given assignments are completed, the respondent was then shown the recording of the process, including their eye movements, and interviewed extensively about their experience, understanding, and thought process.
