a camera rotation in roll. After this rotation the pupil is centered horizontally (top right image). Then a yaw rotation of the camera
aligns the lower eye lid to an approximately horizontal orientation, as indicated by the red rotated line in the top right image. Finally,
a camera rotation in pitch will move the pupil vertically (red arrow in bottom left image) until the pupil is completely centered (bottom
right image).

4.2.2 Start standard calibration

The patient is seated 1.5 meters from the wall where the red laser dots are projected and is asked to
hold their head still and alternate fixating on the 5 brightest projected dots for 1 sec each until asked to
stop by the examiner.Press Start when you are ready to begin recording.
Figure 4-5 Calibration target with laser images.
Figure 4-6 Calibration in progress screen. The big red dot in the Eye in Space plot (bottom right) indicates that the patient
should fixate on the right calibration dot.
During the calibration,a suggested target will be displayed with a large red dot which will move in a
sequence of jumps from fixation point to fixation point, indicating the next desired fixation. With the
help of this display, the examiner can instruct the patient as to which target they should be looking at.
