Designers of visual communication material want their material to attract and retain attention.In marketing research, heat maps, dwell time, and time to AOI first hit are often used as evaluation parameters.Here we present two additional measures 1) scan path entropy to quantify gaze guidance Gardening Book and 2) the arrow plot to visualize the average scan path.
Both are based on string representations of scan paths.The latter also incorporates transition matrices and time required for 50% of the observers Nail Repair to first hit AOIs (T50).The new measures were tested in an eye tracking study (48 observers, 39 advertisements).
Scan path entropy is a sensible measure for gaze guidance and the new visualization method reveals aspects of the average scan path and gives a better indication in what order global scanning takes place.
