Hi Albin,
At this point there is only one kind of gaze data that the Gaze SDK provides that the EyeX SDK does not: gaze point on screen for the individual eyes. The EyeX SDK provides the gaze point on screen only as a single point (“this is where the user is looking”). It is hard to do anything reliable based on the gaze points of the individual eyes, so for now we have left it out of the EyeX SDK. It might be added in the future if we deem it appropriate.
