Hi @treep, the ability to analyse calibration results is only available in conjunction with the Tobii Pro SDK which whilst free to use for the Tobii Pro rage of Eye Trackers, requires the purchase of a special licence in order for it to operate with Tobii Tech range of Trackers, such as the 4C and EyeX.
Certainly, no such ability is exposed within the Unity Engine.
If you could kindly describe in more detailed your hardware and project intentions, we should be able to point you in the right direction for your needs.
