Gaze Path Stimulation in Retrospective Think-Aloud

For example, a prolonged gaze to some widget does not necessarily mean that the user does not understand the meaning of the widget. The user may just be pondering some aspect of the given task unrelated to the role of the widget on which the gaze happens to dwell. Similarly, a distinctive area on a heat map is often interpreted as meaning that the area was interesting. It attracted the user’s attention, and therefore the information in that area is assumed to be known to the user. However, the opposite may be true: the area may have attracted the user’s attention precisely because it was confusing and problematic, and the user did not understand the information presented. A conclusion is that the data recorded by eye tracking seems to call for the user’s interpretation.
