User manual

IMPORTANT: The height of the EyeLink 1000 Tower should not be

adjusted when a subject is using the head support device!

If the subject wears glasses, start with the mirror angle to middle- or high-

position and then gradually adjust it during the camera setup process if

necessary. The “Use Search Limits” button should also be checked so that the

tracker will try to re-acquire the pupil position within a red box illustrated in

the global view of the camera image. Please note that the EyeLink 1000 Tower

mount is not compatible with some glasses (depending on the shape of the

glasses and reflectiveness of the glasses) and therefore you may not be able to

track the subject even after adjusting the mirror angle; the EyeLink 1000

Desktop Mount has a better compatibility with glasses.

Once the mirror angle is set to the intended position, ask the subject to lean the

forehead against the forehead rest on the Tower. Adjust the height of the chair

so that the subject is comfortable and his/her eye line is aligned to upper part

of the monitor. The position of the forehead rest should be just above the eye

brow. The leftmost panel of Figure 3-3 shows a good chair height. The rightmost

panels show the subject seated too high or too low.

The experimenter should also ensure the subject’s head position is vertical by

adjusting the position of the chair so that the subject is seated either closer to

or furtherer away from the table. If the chinrest is used for the experiment,

adjust the height of the chinrest pad so that the subject’s head is comfortably

supported. The user may also adjust the protrusion of the chinrest pad so that

it is furtherer away or closer to the subject by turning the knob underneath the

chinrest.

In the global view window of the camera image, now 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
