Eye Tracking
Eye tracking is a design evaluation method used to visualizeeye movement of a person. Duringusability tests, eye tracking enables the moderatorand further spectators to trace whereparticipantsare looking or not looking, and how long they are looking atparticular locations. This way observers are able to betterunderstand participants’ actions.
Using a special analysis software, the gaze point data of severalparticipants can be superimposed after the test. Thereby, it ispossible to state how exactly the tested object has been perceived.Eye tracking results are visualized as heatmaps, opacity maps orgaze plots.
