Hi @fmcalisto and thanks for your query, great sounding project! However, for assistance in development using the Tobii Pro SDK, we would recommend you to reach out to Tobii Pro Support directly @ http://www.tobiipro.com/contact/contact-support/
Thereafter a member of the team there should be able to help you further. That being said, I believe that the Python Bindings of the Pro SDK does come with sample applications that demonstrate how to capture gaze data directly. Hopefully that should be sufficient to get you and up and running.
