OK. Thanks for the info and making the feature request.
I was looking through the c-interface, and it has a tobii_get_state_uint32 function that returns the ‘current calibration blob’. Would that hold the information I’m looking for (assuming I can get it into Unity)? At least to verify that our users have switched ids?
There is also frequent mention of the function tobii_calibration_retrieve() in the stream api doc, but I guess that function is Tobii-pro only?
