Hi @assulan, The Tobii TX300 is part of the Tobii Pro business department.
This forum is intended for support with the Tobii EyeX and C4 Eye Tracker and associated SDK’s.
Please get in touch with Tobii Pro support directly @ http://www.tobiipro.com/contact/contact-support/ for answer
to your query.
However, I can inform you that the Eye Trackers always have a calibration profile loaded into memory as ‘uncalibrated’
gaze data does not produce any data. Tobii Pro should be able to provide a more thorough explanation and perhaps provide
a workaround for your needs.
