Hey @Grant, appreciate the rapid reply very much! Currently I am using Tobii 4Cs with a Professional license. What I intend to do is compare precision and accuracy of the gaze data before and after a session so that I can make an informed decision as to wether to trust logged data. From how I understand the Tobii Pro SDK documentation regarding calibration, the relevant data does get exposed. How would you recommend integrating that functionality into a Unity application?
