Several other comments are alluding to saccade [1], where your eyes unconsciously jerk around (saccade is the french word for jerk) any vision control system would have to allow for this. In the simplest approach this would be a low pass filter, presumably you could throw a bunch of ML to filter them out more accurately [1] https://en.wikipedia.org/wiki/Saccade https://en.wikipedia.org/wiki/Saccade

> Saccadic eye movement allows the mind to read quickly, but it comes with its disadvantages. It can cause the mind to skip over words because it doesn't see them as important to the sentence, and the mind completely leaves it from the sentence or it replaces it with the wrong word. This can be seen in 'Paris in the the Spring'. This is a common psychological test, where the mind will often skip the second 'the', especially when there is a line break in between the two. Well, looks like I just failed the test, even though I made a genuine effort to read the paragraph very carefully after the the second sentence.

  I missed it too, but jumped back to the opening single quote when I hit the closing single quote and found it. Must be a coding reflex.

Saccades are under voluntary control. They're the fast movements when you switch where you look. There are microsaccades that are similar but don't seem to have any target we understand. In general these, and other microeyemovements like tremors and drifts, are not very well understood, and even their existence can be somewhat quoestioned. Low pass filters are somewhat problematic for eye movements because the altenating slow and fast movements. As a shameless plug here's what I think is still the state-of-the-art method for filtering eye movement data: https://www.nature.com/articles/s41598-017-17983-x https://www.nature.com/articles/s41598-017-17983-x
