The main objective of this work is to understand if a blind user has a good experience when using a support system when moving from point A to point B. To check this, the facilitators performed some User eXperience (UX) tests to analyze how the user interacts with the device. Specifically, tests were made with the modified methods “Thinking Aloud,” “Hedonic/Utility Scale” (HED/UT Scale) and “Positive and Negative Affect Scale.” The study sample included 5 blind participants, aged between 36 and 46 years old, of both genders, with a heterogeneous level of education and technology experience. The instruments used included the following: pretest, post-test, task evaluations, participant observation, and recording of both audio and video. Based on the results, users find the system challenging to use; therefore, applying the method allows developers and analysts to see how, where, and when the system fails to make the relevant improvements. Finally, we should mention that applying these modified methods allows for better target users’ feedback.
