Inquisit Tobii Plugin

The following attributes and properties are supported by the Tobii Eyetracker plugin. To use these extensions, the plugin attribute must be set to "tobii".

To use Inquisit with Tobii eye trackers, perform the following steps:
* Set up the eyetracker according to Tobii's instructions. Make sure it is plugged into your local network.
* Open an Inquisit script that defines the eyetracker element with plugin attribute set to "tobii" (sample scripts are available from our library)
* Run the script. You will be asked to register the Inquisit 6 Tobii Plugin if you haven't already.
