Right sorry, silly me.
Another more general question: I am used to using both calibration and validation in eye tracking, yet I cannot seem to find this option for tobii in inquisit. Is there one, or is the calibration accurate enough?
And if I want to make sure that the participants are fixating the fixation cross for at least 300 ms at the beginning of each trial, I know that I can use:
/ plugin = "tobii"
/ aoidurationthreshold = 300
but do I need to define the aoi as the fixation cross in some way?
Thanks in advance
