First Claim
Patent Images
1. A system for presenting gaze-point data comprising:
- an eye tracking unit for detecting gaze point data of at least one subject;
a camera unit for viewing a test scene and acquiring a picture representing the test scene;
a display;
a processing unit configured to present the picture on said display, and display shapes on the picture with the shapes representing momentary gaze points, detected by said eye-tracking unit, of the at least one subject, with a size of each shape varying to indicate accuracy of the gaze-point data;
said eye-tracking unit to acquire momentary gaze points over a time interval of non-zero length; and
said processing unit is further configured to display textual annotations specifying a respective time of viewing of the momentary gaze points, display lines or arrows connecting the shapes to specify an order of the momentary gaze points, accumulate the dwell time of one or more subjects in each area of interest, and superimpose shaded areas of interest in accordance with statistical measures of the dwell times of the one or more subjects, with the statistical measures comprising at least one of a mean total dwell time per test subject, a mean duration of each fixation, percentiles of the total dwell time or percentiles of a test population having visited each area of interest.

Abstract
A method of presenting gaze-point data of a subject detected by an eye-tracking unit includes presenting a test scene picture acquired by a camera unit, and displaying shapes on the test scene picture. The shapes represent momentary gaze points of the subject.
