If enabled, requires the manual pressing of the

spacebar or ENTER key on Host or Display PC

in order to gather the sample when the

subject is looking at each calibration or validation target. If disabled, the

calibration and validation procedure automatically samples once the eye settles

on a target.

Keyboard Shortcuts: Y = toggle Force Manual Accept on/off.

Clicking the Camera Position Detect button

polls the position of the camera selection knob

to determine the eye to track. This option is only available for the Tower Mount.

Keyboard Shortcuts: K = toggle camera eye autodetect on or off.

Lock the setting of the eye to record eye on the

Search Limits, though not recommended for most subjects, are useful for

images with pupil or CR foils, such as reflections off of glasses or makeup.

Search Limits delimit the area of the camera image (indicated by a red

boundary in the Host PC global view) to be examined for the pupil or CR in the

event that tracking of these is lost. A red shape around the searched area

appears in the Host PC’s global view.

If “Search Limits” is selected

and the pupil position is

moved, search

for pupil is confined to the

area within this box; otherwise, the whole image is searched for pupil.

If Move Limits is checked, the search limit box moves with the pupil.

Search Limits are automatically active with the EyeLink Remote as the entire

image is searched on every frame given that head movement is not restricted.

In Mouse Simulation mode the Host PC mouse simulates eye movement and

can be used for experiment testing and debugging purposes.

Keyboard Shortcuts: M = toggle on/off Mouse Simulation, F4 = toggle Search

Limit on/off, F5 = toggle dynamic updating of the Search Limit area around the

pupil

Record the participants’ eye area or

diameter in pixels. The area is

recorded in scaled image pixels. Diameter is calculated from pupil area fit using

a circle model.

Keyboard Shortcuts: S = alternates between pupil Area or Diameter data
