Inquisit Language Reference
The following extensions to the eyetracker element are supported by the Tobii plugin.
/ calibrationmode = value
/ hostname = value
/ illuminationmode = value
/ ipaddress = value
/ lowblinkmode = value
/ maxfixationtime = maxfixationtime
/ minfixationtime = minfixationtime
/ saccadethreshold = saccadethreshold
/ unitname = value
The attributes and properties here are specific to the Tobii Eyetracker plugin, providing additional Tobii-specific functionality beyond what is provided in the generic eyetracker element. 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 5 Tobii Plugin if you haven't already.
