Demographic data about users were collected prior to the evaluation task using a simple
questionnaire that was either self-administered or evaluator-administered depending on the
participant’s preference.
User experience and usability data were gathered through eye tracking and informal post-test
interviews. The interviews were only conducted when the evaluators observed specific
behaviours during the interaction that needed clarification. Eye tracking is a method to record
people’s eye movements while they are looking at a stimulus. In UX and usability evaluation, it
provides an objective measure of the users’ attention on interface elements throughout the
interaction period (Duchowski 2007). Capturing users’ gaze patterns (i.e. saccades and fixation
points) provides accurate information on what the areas of focus were and which parts of the
interface they ignored.
