Grant, thank you for the info.
The Interaction API indeed provides mm coordinates, but they seem to be not very precise (differences in cm range) – monitor was calibrated as suggested by the setup.
Is there an option to get more exact coordinates relative to the eye-tracking device?
Re Z-coordinate slowness: In contrast to the C++ API here in the Interaction API, the Z-coordinate is quite speedy – possibly there is something wrong/different in the C++ API?
Will the Interaction API be available for C++? When?
Are the Tobii pro devices more precisely? I already wrote a request to [email protected], but did not get an answer until today.
Thank you in advance.
