of every experiment. A visual indicator, illustrated in the figure below, is present

on the right hand side of the Calibrate, Validate, Drift Correct, Output and

Record screens and gives the operator a complete and continuous status report

of the camera image. For the EyeLink Remote, status of target tracking is also

provided

Figure 2-12 EyeLink 1000 Status Panel

For both the Pupil and Corneal Reflection status reports, the left Status Panel

column corresponds to the left eye and the right column corresponds to the

right eye; the status column representing the eye not being used is disabled.

The Status Panel indicators are summarized as follows:

Pupil

OK (green) Pupil present and can be tracked at selected sample rate

SIZE (yellow) Occurs when the pupil size is larger than the maximum

allowed pupil size.

ISSING (red) Pupil not present;

Corneal (only operational in Pupil-CR mode)

OK (green) Corneal reflection is present and can be tracked

MISSING (red) Corneal reflection is not present

Target (only available in EyeLink Remote)

OK (green) Target is present and can be tracked

MISSING (red) Target is not present.

EYEDIST (red) Target is placed too close to the eye on the vertical

dimension.

ANGLE (red) Target has too large an angle to be recognized properly.

When working in the Output and Record screens, if the Pupil Size warning is

on, at least one sample was interpolated by the system and is indicated by (Int)

appearing beside the ‘Pupil’ label in the Status Panel. All status flags remain on

for a minimum of 200 msec, even if the condition that caused the warning or

error to be raised lasted for less than 200 msec.
