Has anybody else noticed you can 'break' persistence of vision? For example, if you look at a really fast moving object, like a spinning tire, or ceiling fan it looks blurred, but if you dart your eyes away from it, or towards it you can see a single 'frame' of the action?

+NicolaiGD This! It happens because your vision essentially 'freezes' when your eyes move from one spot to another. Otherwise, everything would be a massive blur whenever your eyes moved even a small amount.

+Álvaro Astrada Yes, but at the same time, you don't have any pressure here when learning. In school you actually have to learn, and most of the time you don't want to know. Here you're actively clicking a link and sitting down and watching a video. That will of course make it more enjoyable. Also, you can only explain this phenomena, but can you calculate anything? Could you understand it if I were to use another way to describe the same phenomena? In school you learn more deeply then what a youtube video can give you. Or atleast this is what i think of the subject.

ᅚ ᅚ What we're saying is, if an average school teacher tried to teach the exact same information thats in this video, it would take much longer and they wouldn't explain it as well. It's not necessarily "what" you teach, it's "how" you teach. Thats what separates the good teachers from the great teachers.

I remember really hoping after he spoke to the professor he'd talk to a biologist and explore what environmental pressures led to homo sapiens developing that trait of persistence of vision, is it just to maximize the info you receive to be able to better see threats, or just a more efficient thing that doesn't really have a dedicated evolutionary advantage

I am a HUGE fan of yours - you are a genuinely likeable, fun, curious person and even coming up with the topics for your channel must be a labor of love. 2. I really and truly appreciate your quiet, gentle ministry of the Biblical verses at the end of each episode above the pic of what I think is Reepicheep - the Narnia series is another such example of beautiful, gentle, calm ministry of Christianity. I wanted to tell you how much that means to me.

@darcgibson5099 8 жыл бұрын

I hate how the news (at least here in a couple UK newspapers) they call scientists "boffins" or some equally disrespectful term that's basically looking down on them for being scientists. Knowledge is seen as a negative thing because people are jelly they don't have it ;^). School's need rigorous and interesting curricula to capture people's minds. Not "Intelligent design" or the other nonsense that American school boards viscously fight to put alongside factual things like evolution or plate tectonics. "Just teach the controversy!" there is literally no controversy amongst scientists.

Also, no American schools (or school boards, for that matter) I've ever been to "fight" to put intelligent design in the books. In fact, it's rather ironic that you claim knowledge is shunned while simultaneously spewing ignorance about such matters. There are of course outliers, but pointing to outliers as the norm is simply ignorant.

The one issue I have with this video is that Destin says that if it wasn't 30fps we would begin to see flicker. That wouldn't happen because the frames aren't displayed and then removed before showing the next frame as a film projector does. What actually happens is that one frame is shown and then instantly replaced by a new frame so that there is always a frame visible. If you lower the frame rate, the video would just begin to look choppy and unnatural and at a certain point, our brains wouldn't detect it as motion at all, but as a slideshow of images.

+APPLBL00M This is the same thing with modern displays, where cloned (persistent) frames where inserted between active frames to ensure the image appears smooth and doesn't strain the eyes. This was a significant problem with CRTs running at or below 60 Hz as the image appeared to be flickering heavily; often causing eye-strain for extended use. Edit: There isn't actually another frame inserted between frames, but rather the previous frame is kept on screen until the next frame is displayed. However, on Nvidia Gsync displays, cloned frames are used to help with screen tearing.

@tubester358 8 жыл бұрын

+Christopher Moon - There are frames synthesized and inserted between frames for displays that 'fake' higher framerate (like high framerate TVs usually have). There's even a computer software that can do this for any monitor/laptop called SVP (Smooth Video Project) which can make your video appear extra slick, but it works best for predictable motion like on live action films - it's very choppy for anime, games and things with more erratic motion. I don't use it 'cause it was annoying & buggy/laggy, lol.

My fiancee was freaking out because when she went to try out her wedding dress that she tried out 5 months ago looks yellow. Her mom, sister, and bridesmaid also agreed and freaked out. They accused the store that they were selling her a completely different color (another version of ivory). They were 100% convinced that the store were pulling something funky. She came crying, and I asked her: What was the weather when you first tried your wedding dress? Answer, it was a super bright, clear day. When she went the second time, gloomy, winter day. Also, ask her to show me a picture of the time that she tried her dress back in July. Well, she had a full, summer tan and dark hair. Second time, her skin is pale from the winter, and she died her hair blonde. I told her to try dyeing her hair back to dark brown, and get a spray tan. I explained that color is defined by three elements: the object (constant), the observer (brain - not constant), and the light source (not constant). She went back to try on the dress. She came back crying tears of joy, "babe, you're a genious!". Her dress was a brilliant and beautiful as she remembered. I told her, I'm not a genious. I watch SmarterEveryDay.

This reminded me of when I was a forestry student and we were covering stereoscopy in photogrammetry. Basically one looked at two ariel photographs taken from slightly different angles through a viewer. From this you get a "3D" image where you can infer "height", allowing you to work out yield from stands of trees. It's also used by the military to assess heights of buildings when looking at targets. What I and one other found was that we couldn't see the "3D" effect at first; I had to "tell" my brain to allow the image to pop into view. The lecturer said that this was a problem with folks with high IQ's; though I fear he was stroking our ego's on that one.

The way is works in the lighthouse pic is because your eyes hate seeing the same colour for a long period of time so they sort of start subtracting that colour from your vision. When you see the uncoloured picture, you see the subtractions (negatives) of the inverted colours, thus you see the right colours.

@Zoronii 8 жыл бұрын

The technical term is "cone fatigue", which is literally the cones in your eyes getting tired. When the color you're staring at goes away, the tired cones stop perceiving that color as it recovers, meaning its complimentary color overpowers it and appears in your vision.

The effect usually doesn't last that long in this case though unless you are basically continually playing the game through several songs without stopping or giving your eyes some time to rest between songs..... probably not healthy doing that though.

Maybe you guys could make a video about that "inner experience"?

That has implications for lighting, too. I noticed while cycling home from a friends house a couple years ago that with my headlight on medium, the tire tread pattern on my front tire was moving slowly backward. A classic strobe effect. Apparently, LEDs work best driven at a certain current - to dim the lights, circuitry just cycles them on and off rapidly. In essence, I was riding in the dark half the time. Which also may be a problem for smart cars - depending on the frame rate of their cameras, they may, or may not see some types of LED lighting as being on.

@thebigitchy 8 жыл бұрын

Kind of. As with TV, the point of having a higher frame rate 60p rather than 30p is because you get more frames in a period of time. While your eye can't tell the difference for most things, it's important when you have small fast-moving objects on screen, because then they will be spacially closer together and the brain will connect the movement better.

@elviswjr 8 жыл бұрын

+thebigitchy Despite what people claim about the capabilities of the human eye, I can almost always tell the difference between 24-30fps and 60fps, especially with camera pans or fast movement. It just looks smoother and more natural. 30fps looks fine when you're not comparing it, but when you do compare it, you can see a clear difference. This means that, like you said, 60fps and higher is important for fast moving objects, especially in video games because you can actually see the difference and possibly react faster. However, for some reason, perhaps because we're used to it, many people (myself included) find that 24-30fps looks better with movies. It doesn't look more natural, but it looks more cinematic.

Even though the brain (or eye or optic nerve) merges pulses of light together, the effect isn't perfect. Some of the flicker carries over into the rest of the brain. It may not be enough to induce seizure or migraine, but does affect your performance (web.mit.edu/parmstr/Public/NRCan/nrcc38944.pdf). I want to say you need around 1000 Hz to be completely safe, but I can't find a source and it's probably just a rule of thumb I came up with the last time I researched the subject.

I'd say so, although much higher than that and your brain doesn't perceive it anymore. So I think once you pass 60 FPS it becomes pointless.

In 1996, I invented this principle (quite early, but probably I wasn't the only one to think of this) and came up with a prototype called the 'Ledsaber' that used 30 red leds in a row and a preprogrammed series of images, slogans and expressions that would become visible when manually swinging the ledsaber up and down through the air. I was limited to using red and green leds to illustrate the concept because white and blue leds had only just been invented in those days but were not readily available yet! The story of my life!

Once upon a time I was a security supervisor at an installation where security was taken seriously. When it was foggy the black & white monitors displaying images of high interest areas would show an almost solid block of gray mist even when the camera lenses were clean and dry. Even after the fog or mist had almost cleared so a human (put in place to temporary replace the degraded mechanical view) could easily see along the entire area the remote monitor covered. I do not remember any difference in how the fog disrupted the display between night and day. After studying the monitors and then going into the field to see for myself the clarity of vision humans had compared to the monitors I hypothesized the monitors were literal in their display of the data they received from the cameras. I thought the monitors displayed every droplet in the mist in a two dimensional manner along the length of view. So the monitors added up all the droplets existing in the infinitesimal slices(?) of the camera's collection of data causing the monitor to display a solid misty view. I figured why the same length of space with slight mistiness seemed relatively clear to human sight was due to our brains doing some processing to see through or around the areas containing droplets. Although I was curious; it was before the great internet and time prevented me from driving to a library to research the phenomenon. I will be reading up on Dr. Stuart Anstis' visual perception papers! Thanks for the tip Dustin.

@OrigamiMarie 8 жыл бұрын

+EDITHFIVE There's another possible reason for the camera trouble. Some cameras are more sensitive to ultraviolet light than human eyes, and small amounts of fog can reflect a lot of ultraviolet light. So what seems like a mostly cleared fog situation to your eyes is still ultra-violet opaque to the camera (which saves all of that ultra-violet reflection as plain white). A yellow filter over the camera can help a lot (because it keeps that ultra-violet light from getting to the camera sensor).

@stertheder 8 жыл бұрын

+OrigamiMarie YURIKA! Thank you OrigamiMarie, your simple explanation just helped me realize why yellow-lensed sunglasses cut down glare so much. By removing the ultra-violet light before it gets to the eye, you cut down on the amount of light the eye has to ignore, thus reducing the strain. (Or, at least this is how i am thinking about it, i could very well be wrong.)

@OrigamiMarie 8 жыл бұрын

+stertheder Yes! The yellow filter takes care of the near-ultraviolet and actual ultra-violet (that some people can sort of see) light. That short-wavelength light scatters more easily in fog than longer wavelengths, and this gets in the neighborhood of explaining why the sky is blue. Sunglasses can do two main things, filter out all of that short wavelength scattered light (with yellow), and/or filter the light that's polarized in a particular direction (which takes care of a good chunk of the sunlight-reflected-off-cars problem -- the light that bounces to your eyes is all waving in about the same plane, and can be filtered by tiny little lines like window blinds). Oh, and fun with polarization gets over toward movie 3D glasses technology . . . so many linked things :)

+Dennis Davis That may depend, exactly what biological factor determines the persistance and how can it be improved? Also, what advantages would it have on an animal if it was smaller? when does the duration of the persistance stop being relevant for anything practical? I could imagine other animals having a longer persistance duration, some primitive animal, i can also imagine an animal that needs a shorter persistance rate and a faster "refresh rate" if there is such a thing, perhaps a predator which relies on identifying his prey in water in a turbulent situation, and i also wonder if there is such a thing as an "exposure rate".

+Nyx & Hemera I think dogs would require a faster frame rate in a television to really watch it. Their shorter persistence of vision apparently gives them sharper perception of movement.

@ABaumstumpf 8 жыл бұрын

+Dennis Davis Simple answer: Yes. A part of the persistence comes from the chemical reaction in your eyes - the cones and Rods receive light and send neurotransmitters to the nerve cells. This take a bit of time, and the cons/rods also don't have an unlimited supply of the reacting chemical - thus when you look at very one-colored scenes, the eye gets tired pretty fast and that particular color fades out. if you wear Red glasses for example, after some time, you will notice that the scene doesn't look all that red any more. But if then you take them off everything appears to be blue. Another factor is the brain it self, as it is filtering out a huge punch of the visual information to not overload your conciousness. (That also leads to some strange phenomenon with people who's blindness origins from the brain, not the eye: Jumpscares work on them, but they have no clue why they got frightened :P )

It varries a lot based on belence of rods and cone. Just as an example flicker fusion in humans occurs in the lower 20s hrz because our vision is very sensitive to color but not to light or motion.

Negative afterimages are caused when the eye's photoreceptors, primarily known as rods and cones, adapt to overstimulation and lose sensitivity. After overstimulation and the eye remains too steady, the photoreceptors that are constantly exposed to the same stimulus will eventually exhaust their supply of photopigment, resulting in a decrease in signal to the brain, then the brain will interpret it as negative afterimage.
