Absolutely. Our brains have to try to make sense of stuff using a prediction model. The Bill Bryson book ‘The Body’ does a good job of going over this in a fun way, but the fact that it takes about a fifth of a second for light to go from our eyes through the optic nerves and into the brain, means that our consciousness has to predict / pretend what is going on precisely at this moment by speculating / guessing / imagining, and then making the data fit retrospectively. A fifth of a second lag is quite long amount of time, but we are just really good at reordering and filling in gaps, and the brain basically never lets on that reality is behind.
Now if we could tap into that signal and feed the reprojected VR picture directly to the brain…
It’s like when you look at a mechanical clock, for the first second it seems like the second hand is moving just a tad slower than the next one.
Turns out that when you move your eyes quickly you are pretty much blind and the brains retroactively fills in that gap with the first thing your eyesight stops upon.
edit: ok, I realise my limited vocabulary might be confusing so I’ll just quote somebody else:
It’s a trick that your brain is playing on you.
Obviously, our eyes are the primary “input” for our vision. But the business of “seeing” mainly takes place in our brain, which tries to make sense of the information coming from our eyes, and construct a meaningful vision that we can use.
Our eyeballs move from one target to another in rapid, jerky movements called saccades
. During this jerky movement, any images transmitted by the eyes would be, at best, a blur - so the image-processing centre in our brain just ignores it. There’s a system that allows the brain to know when a saccade is about to start, and when it ends, so the brain is able to avoid dealing with the useless, blurry images during that period.
But this means that image-processing part of the brain now has a series of gaps in the video stream, which it attempts to fill in and smooth out. One of the ways that it attempts to do this is by backdating the new image that comes in after a saccade and extending it backwards into the blank time immediately beforehand, so that it appears that the image existed longer than it really did.
This is the reason that the second hand of a clock appears to be frozen when you first look at it. One part of your brain has done a “cut and paste” with the image so that it can present a video stream to the rest of your brain that appears to be smooth and complete, instead of jerky and with blank spots.
There’s much more information on this well-known phenomenon available, including here on Wikipedia
Good Lord…I’m glad someone has finally explained this to me. I thought it was ME controlling space/time. Darn.
Man that wing is smooth.
That’s my baby! UAL 767-300 (PW4060). I LOVE that departure out of LA.
Do we have any airbus a320 pilots on hand to answer an odd question I have? Or a fitter?
Weeps for the loss of @CygonParrot… (I can report he is doing well though!)
Depends on how odd it is but perhaps I can help?
I was a check airman on it…25 years ago.
I didn’t even know there was a green needle A320…!
The LS8 looks like such a sweet machine. Our club has an LS4 which I have yet to get checked out in. By club standards it’s very nice, but nothing close to the 8. Also…doesn’t Italian just seem like a language perfectly suited for aviation?
Good to know the MD80s will live on in some capacity. Can’t wait to see a beat up AmeriJet one in twenty years…
Do they ever give a Type I deice fluid send off?
Type I is the lubricant we spray to make sure we don’t get stuck on the way to retirement…
Thought it was required to get the captains wallet out
That must only be used to buy toys.
And beer.
