Ah yes, now you are talking my language. The eye and brain are wonderful thingsOur 'vision' is not defined by the eye, the visual cortex of our brains is what does the magic. The 'raw' image from our retina is upside down, interrupted by blood vessels, and actually only have tiny FOV. The 'image' we all see right now doesn't exist in any optical setting, it's a construct produced by our brain.
It reminds me of a time when I was debating the merits of 4k TV's, what size they need to be, how far away you need to be seated and all that jazz. Doing some testing on a 50 inch TV from almost 20ft away, I could quite easily see the benefits. However, when I used a test pattern, which is basically a checker board of black and white pixels, all I could see was grey.
I had to get really close to the TV before I could make out the individual pixels. At the same time, I was still sure I could see the difference much further away, but couldn't really prove it. My theory was that my eye could definitely see the difference, but my brain was like, no, you can't. It just decided to throw away the information it was receiving and turn it into something different, which was just a grey screen. Possibly trying to save me from eye strain?
Anyway. It was later one morning when I was sitting outside having a coffee, contemplating the meaning of life, when I had the Eureka moment. The low sun was shining when suddenly something caught my attention out of the corner of my eye. It was the glistening of a single strain of spider web, which had a little bit of moisture on it from the morning dew. Less than the width of a hair, and I must have been 30ft or so away and there it was, clear as day. If I tilted my head slightly, the sunlight wasn't lighting it up and it became invisible again. It never changed in size, but depending on what way the sun hit that single strand, it went from being invisible to visible. It was the high contrast that made my brain take notice. Once that high contrast was taken away (by tilting my head a little) my brain decided not to see it again.
Thats when I realised that those 4k charts that tell you screen size to viewing distance ratio are a pile of rubbish. If you sit x distance, you need a TV of y size.
The brain does a wonderful job of bringing important things to your attention and throwing away stuff that doesn't really matter. Tesla trying a vision only FSD process, based on the concept of having several sets of eyes is an interesting one but one I can't get behind. Why try to replicate a human eye (and brain) which has inherent flaws, when you could replicate a hawk? They can see way further than we can. Plus, how our brain creates a stereo image is something that Tesla can't really replicate as effectively.
Well that's a weird post when I read it back to myself, but may as well hit the reply button anyway
