Inquisit SR Research EyeLink Plugin

The attributes and properties here are supported by the SR Research EyeLink Eyetracker plugin. To use the plugin, the plugin attribute must be set to "srresearch".

To use Inquisit with SR Research EyeLink eye trackers, perform the following steps:
* Set up the eyetracker according to the EyeLink User Manual. Make sure it is plugged into your computer's network port.
* Open an Inquisit script that defines the eyetracker 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 5 SR Research EyeLink Plugin if you haven't already.
