Briefly, if you are simply using python code to process the gaze data as received directly from the Tobii Stream Engine (or Interaction Library) SDK and are not storing the gaze data or performing analysis then the getting started Tobii licence is appropriate for your needs.
We do however not permit the creation of a Python ‘wrapper’ that creates an emulated API to extract gaze data as outlined in our Getting Started Licence:
2.2 d) Your Software must not allow other software to access Eye Tracking Data that originates from the Licensed Software.
Hopefully this clarifies our position for you, please do get in touch should you require any further information. Best Wishes.
