Reply To: access to unfiltered gaze point data in the Tobii Stream Engine

[Grant [Tobii]]

Hi @simonsmith, the pupil size and separate eye gaze streams are advanced metrics which are only available with the Tobii Pro SDK

In order to use the Tobii Pro SDK with the 4C Tracker you must purchase a Research development license.
