Except that your natural saccade is also wired to your motor neurons in your head and neck. For example, there's a strong connection between the neurons that fire to turn your head 10⁰ to the right, and the neurons that fire to turn your eyes 10⁰ to the left, which allows your eyes to fixate on something even as your head moves.
Indeed, it's almost impossible to turn your head slowly without your eyes fixing on points in your field of view, and then saccading to the next point. Try it. This is a hard-wired response. (You can perform some tricks to do it, like completely blurring your eyes, but that's not really the point.)
Meanwhile, if we watch a video with the camera turning, it's easy to keep our eyes staring straight ahead.
This shows that there is going to be a difference between a head naturally turning and watching a video of a head turning.
I think you're describing saccades as just being the "dropping out" of frames, and not including the extremely-relevant motion that our eyes do during a saccade.
- jvanderbot 3y agoI appreciate the attention to detail in this thread. I think the only thing I can say here is - I dont see anything weird when I turn my head, and when FPS games added blur to "character moves his own body", it felt much less natural, not more. So, to answer question a few posts up "how would we do it?" I'd just say "The way we always have before we got enough GPU to make everything look like a movie"
