Goal: Measure the accuracy of calibration of a subject.
Implementation: This interface visually displays calibration error for each eye for 17 points displayed on the screen. Average calibration error between all points is presented for the eye-gaze (averaged point of regard between the left and right eye) and left and right eye separately. This tool is extremely useful to determine if the eye-tracker is appropriate for a specific subject, i.e., high error value will provide high noise for measurement experiments.
Requirements: Tobii eye-tracker
