i. Freedom of head movement describes the volume in front of the tracker in which the user must have at least one of the eyes. The numbers are
specified parallell/orthogonal to screen surface, assuming eye tracker is at 20 degree angle to screen.
ii. Gaze accuracy describes the angular average distance from the actual gaze point to the one measured by the eye tracker.
Accuracy under ideal conditions is measured with users placed in the center of the eye tracker track box with the head resting on a chin rest, and the
room and screen illumination constant at 300 lux.
Accuracy across head box is measured with users after calibration systematically positioned at varying positions ranging from center of the head box up
to +/- 15 cm horizontal, +/- 10 cm vertical and +/- 10 cm distance.
Accuracy across varying background illumination is measured with users’ head resting on a chin rest, and after calibration modifying background
illumination from 1 to 1000 lux.
iii. Gaze angles describe the quality of gaze accuracy when user looks at the upper two corners of 16:9 ratio screens, @ 60 cm user distance to Eye
Tracker.
iv. Gaze Precision describes the point-to-point variation between individual gaze samples (here specified with binocular data, ie both eyes, and measured
on artificial eyes). Gaze Precision with Stampe filter is with Stampe stage 2 noise-reduction algorithm applied to raw data (Stampe , Behavior Research
Methods, Instruments & Computers 1993, 25 (2), 137-142).
Precision without filter is based on raw data, without any de-noising filter applied, either inside or outside the eye tracker.
Precision under ideal conditions is measured with users placed in the center of the eye tracker track box with the head resting on a chin rest, and the
room and screen illumination constant at 300 lux.
Precision across head box is measured with users after calibration systematically positioned at varying positions ranging from center of the head box up
to +/- 15 cm horizontal, +/- 10 cm vertical and +/- 10 cm distance.
