An EyeLink 1000 Tutorial: Running an Experiment

By default, the “Illuminator Power” level is set to 75% at the recommended

distance. If the Desktop Mount is placed too further away from the observer or

if you find the pupil is not reliably acquired, you may consider increasing the

illumination level to 100%.

Now proceed to section 3.3 “Setting Pupil Threshold”.

3.2.4 EyeLink Remote Participant Setup

The EyeLink Remote is designed for applications where a chin rest or head

mount is not desirable or perhaps even possible (i.e., patient work, gerontology,

children, etc.). The EyeLink Remote provides 500 Hz monocular tracking as well

as 500 Hz head distance estimation via the use of a small target sticker placed

on the participant’s forehead.

If your system is licensed to use the EyeLink Remote mode, take the following

steps to set up the camera and perform image adjustments.

1) For the EyeLink Remote, affix the 16 mm lens (shipped standard with a

short adjustable focus arm) to the high-speed camera.

2) Desktop Mount users should check that the camera is in the level

position (the elongation of the camera should be parallel to the table and

the upper surface of the camera will align smoothly with the top of the

mount, with the Camera Screw in the topmost position). If the camera is

not in this position, loosen the Camera Screw at the front of the Desktop

Mount and move it to the top end of the slot. Hold the camera with its

elongation parallel to the table and its top surface flush with the mount,

and tighten the screw. Dimples on the camera fit into projections on the

mount to ensure that the camera is in the proper position. Plug in the

illuminator cables and the power cable into the camera. Also make sure

the camera data cable coming from the Host PC (the end with a right-

angle connector) has been connected to the back of the camera and

tightly fastened with the thumb screws.

3) In addition to an active license (programmed in the hardware), the

EyeLink Remote requires version 4.0 or later of the EyeLink 1000 host

software which can be downloaded from the SR Research Support

website (https://www.sr-support.com/forums/showthread.php?t=179).

This can be done easily through Windows Explorer. Be sure to back up

(e.g. duplicate) your existing host ELCL\EXE directory from the EYELINK

hard drive partition before upgrading to the latest host software. You will

need to copy the .SCD file for your camera from your old ELCL\EXE

directory to the new ELCL\EXE directory. Should you accidentally
