Hi @hmlee, it sounds like you are using a Tobii Pro series of eye Trackers? Could you kindly confirm which SDK and model of eye tracker you are using please?
However, I can tell you that yes the gaze point is averaged between the left and right eye, however with the Tobii EyeX Tracker this data is not available separately.
So yes you are correct when you assume that the ‘final results’ is the data that is exposed with the EyeX tracker.
For scientific research and the full range of eye tracker data, you are required to use the Tobii Pro range of hardware and software.
