Remarks

To use Inquisit with SR Research EyeLink eye trackers, perform the following steps:

* Set up the eye tracker according to the EyeLink User Manual. Make sure it is plugged into your computer's network port.

* Open an Inquisit script that defines the eye tracker element with plugin attribute set to "srresearch" (sample scripts are available from our library)

* Run the script. You will be asked to register the Inquisit 7 SR Research EyeLink Plugin if you haven't already.

How to Program the SR Research EyeLink Eye Tracker Plugin

Examples

The following defines an eyetracker element that connects to a SR Research EyeLink eyetracker at the given network ip address.

<eyetracker>
/ plugin = "srresearch"
/ ipAddress = "168.192.0.22"
</eyetracker>

The following defines a text element that displays the current width of the right pupil:

<text rightPupil>
/ items = ("Right Pupil Width: <% eyetracker.lastRightPupilWidth %>")
</text>
