With eye tracking, there is the math of tracking two tiny pin dot holes and psychoanalyzing them using psychology for things like marketing.
All fov is paired down to two tiny pin dot holes the mind sees. This is termed the ipd but its what the person is psychologically considering as well.
Without those two tiny pin sized holes the person can't see anything, all fov is irrelevant except those two tiny holes psychologically.
And since science rejects what is not reproducible, if the study group disagrees on what the ipd sees and is psychologically relevant then the science is not reproducible so is useless for things like marketing.
Meaning if the scientists employ streetwise "Jamal" to watch the Indian named "crow may fly", and psychoanalyze him using the eye tracking this assumes ipd is correct.
