An EyeLink 1000 Tutorial: Running an Experiment

Ask the subject to be seated. Adjust the height of the chair so that the subject

is comfortable and his/her eye line is aligned to upper half of the monitor. Ask

the subject to lean her/his forehead against the forehead rest and adjust the

height of the chinrest so that the subject’s chin sits comfortably on the chin

rest pad. If necessary, loosen the Lock knob on the Desktop Mount to adjust the

tilt of the camera so that the intended eye image appears in the center of the

global view of the camera image. If the camera does not stay as configured,

tighten both the Friction knob and the Fest/Lock knob once the vertical

position of the eye is in the intended camera image.

IMPORTANT: If the camera image is tilted 45 degrees counterclockwise, please

check whether the “ELCL Configuration” setting in the “Set Options screen” is

set to “Desktop (Level)”. If the camera image is tilted 45 degrees clockwise,

check whether the camera is set to the horizontal position on the Desktop

Mount. If the camera image is rotated 180 degrees, then your Host PC software

is probably for the wrong Desktop mount – please update your Host PC software

from the support website and choose the Host PC software based on whether

your illuminator is on the left or right hand side of the mount.

In the global view window of the camera image, move the Host PC mouse cursor

on top of the pupil position and double click on the left mouse button. The

camera image for the eye should now be displayed in the zoomed view. If the

pupil is detected, a green box and the cross now will be drawn on the eye image.

Please note that for most subjects, you will just need to adjust the height of the

chinrest and chair to get the intended camera image, without changing the

Desktop Mount settings. However, for subjects wearing glasses, depending on

the shape and reflection of the glasses, you may need to make slight

adjustments to the Desktop Mount (e.g., move the camera slightly left, right,

forward or backward, or adjust the angle of the illuminator and camera) so that

reflections from the glass will not interference with pupil acquisition. The left

panel of the following figure illustrates a good camera setup whereas the

reflections in the right panel block the pupil image, especially when the subject

looks in the direction of the glass reflection.
