Hi @torrero007, interesting question! Within the Core SDK, all calibration is handled by Tobii’s own Core Software so this API does not expose any significant details regarding the calibration profile.
I suspect therefore the best bet is to query the currently loaded calibration via the Tobii Pro SDK.
Looking at the available documentation online (http://developer.tobiipro.com/commonconcepts/calibration.html) perhaps you could try to call the function:
CalibrationStatus.SuccessLeftEye
which may return a non-successful output if the calibration was previously binocular. You can also reach out to Tobii Pro Support and their Pro SDK specialist may have a better suggestion.
Please do let us know how you get on. Best Wishes.
