Here's another: the human ear is phenomenal at determining where in 3d space a sound is coming from. Most animals can only determine direction and can't really place a sound vertically. Watch what your cat or dog does when they're looking for the source of a noise, it takes them a lot longer.
I've heard that this is the reason dogs will tilt their head when looking curiously at something, as this lets them better differentiate sound positions vertically.
iirc it's because human ears are slightly offset to each other vertically. The brain then calculates the time difference it takes each ear to hear it. Basically triangulation.
I've never liked this explanation because if that was all there was to it, it would still only localize to a slanted line in front of us.
Say for example the right ear is higher (I tried finding which one normally is, but couldn't find a good answer) in this case it would not be feasible without other clues to tell the difference between a sound being higher up and slightly to the left, or lower and slightly to the right. It's not a significantly different situation from the ears being the same height.
In reality there are other clues, largely based on the shape of our ears slightly changing the sound in learned ways based on the angle it comes from.
Your tongue is also super tactile. We spend most of our toddler years discovering this.
You can look at anything around you, anything, and your brain knows exactly what it would be like to lick it, even if you've never done it before. Taste, texture, residue etc.. it's quite freaky
Oh and my thighs are really good at imagining my phone just buzzed.
You have to close your eyes, open your mouth wide and put your tongue out for the desired effect. Maybe it helps if you have some bystanders who cheer you on.
When I was an adolescent, I dreamt that I performed oral sex on a woman by putting my entire head inside of her vagina. Turns out that cunnilingus is nothing like my premonition, but I certainly had the texture figured out.

my thighs
Thanks... My body doesn’t really need sleep anyway.
Wait y'all can pick the correct thing out of your pocket regularly? I'd say I have a 10-20% error rate. At least once a week I'm standing in front of the staff room door wondering why my car key is in my hand.
The brain is good at taking the information given it and creating a virtual image, including filling in missing parts. Both for touch and for the mention of hearing to calculate location. It can also be fooled because of this wiring, as it tries to find patterns where they may not exist.
Your brain also has a model of the reality it’s interacting with. If the tactile sensation matches something in the library, that’s the image that gets pulled up.
This system is far from perfect but usually it works pretty well. When it fails, you get false positives, illusions etc.
Idk... Sometimes I end up with nothing but keys in my hand and think I forgot my lighter just because the FOB for my car is the same shape and size as a BIC.
Too bad that my brain apparently still can't figure out the difference between they keys for my front door, shed and bike lock. Still requires 3 tries just like with USB sticks.
I disagree, if my pocket is busy I need to take things out to tell the difference between them. Also, my hands can't tell the difference between my cards.
I wonder if this is an acquired skill. I'm reminded of working on cars and having to build "touch sight" where you "see" things hidden behind an engine block or other obstruction by feel alone.
Euro coins have different knurling around the edge of the coin for accessibility reasons. It has the side effect of helping a lot when trying to find the right ones blindly in your pocket.

South America too, right?
As an American, when I travel and see different shaped coins in different countries, some with holes in the middle even, just trips me out, seems so weird. We're so used to standard round feels similar coins here.
A nickel is smaller and thicker, and has a smooth edge compared to the quarter. Can you not tell the difference?
When you're jiggling around in your pocket for it and there's other coins in there too, it becomes harder to do.
I'm not saying there's a 0% chance of figuring it out by touch alone, just that by touch identifying a coin (vs a not-coin) is a lot easier to do than by touch identifying what amount an individual coin is worth. (In the U.S. at least.)

I thought it was because their snout blocks their vision when they try to look downwards at something?
My cocker also does the head tilt, they do it every time someone talks about treats, food, scrithes, walks and the sort.
GSD does it like she knows what you said and reacts well, like a kid.
And crazy head tilts on hearing bread, walkies or chicken.
The tilts are usually when looking directly at the subject, could be auditory and visual both.
the human *ears. we need both ears working together to determine the source of a sound.
teamwork makes the dream work, people.

If someone wants to read an interesting (but complex) explanation of how it works
iirc it's because human ears are slightly offset to each other vertically. The brain then calculates the time difference it takes each ear to hear it. Basically triangulation.
Triangulation is 2 dimensional, the 3 dimensional equivalent would be "tetrahedralization".
I've never liked this explanation because if that was all there was to it, it would still only localize to a slanted line in front of us.

Wait what?
One blindspot is that the ear is not good at determining whether the sound comes directly in front or back of the head.

Siri, how do I unthink a thought?
Alcohol, ridiculously large amounts of
Weed is better for forgetting. Alcohol is better for not caring.
I'm going to lick everything tonight.
MDMA is better for that
Yeah, if you tilt your head back and pretend you're shaking a salt shaker into your mouth, you will actually taste salt.
I don't taste anything. Does it matter how hard I shake it?

Use two hands.

There are 100% women who would be into that. I'm not saying they're common, but I may have met at least one of them.

Also locating needed nightstand items in the dark of night
I must have gotten a defective one, then. My hand sucks at that.
The area immediately before your hand is also really good at letting you know the time.
What's in my pocket?
handses
Ohhhhhh, tricksy hobbitses. We hates them.
I'm more curious about what's in the box.
Pain!
Without love?
It is a quote from Dune
Gaius Helen Mohiam: The test is simple. Remove your hand from the box, and you die.
Paul Atreides: What's in the box?
Gaius Helen Mohiam: Pain.
Ah. My original reference was to Se7en:
https://youtu.be/1giVzxyoclE
(Warning, spoilers for a thirty year old movie)
My second reference was to a Three Days Grace song:
https://youtu.be/Ud4HuAzHEUc
(Warning, song from ... Maybe fifteen years ago?)
Oh yes Se7en, such a great movie 🍿
It's really nearly 30 years old, damn..
I still vividly remember when the film was in cinema.
Great song. 3DG was so good back then.
Lint.
Pocket sand
We're also the absolute best at throwing.
Want to truly understand how good it is? Try getting a specific thing out of a pocket with a thick glove!
As a single dude, I can tell You, that's not the only thing a human hand is good at.

Keep sloshing your feet in there, and you'll hurt it. Beware of the tentacles
There are over 1 trillion nerve ending in your hand
Just kidding I made that up
"And the average human only utilizes 10% of those nerve endings"

You can also scratch pretty much any part of your butt crack just by feel.
With your hand.

With whatever is in your pockets.
There's a hole in my pocket 😏

Maybe you could apply different tapes or something to the keys to tell them apart.
Exactly correct!

And human eyes are incredible at seeing things
Human balls are incredibly great at feeling immense pain at even the slightest slap with a riding crop.
It can easily tell what item is a coin, but how much that coin is worth is hard for it to do. (Trying to grab a nickel vs a quarter, etc.)

Yeah I could definitely identify each euro coin by feel.
US coins too. Big, small, thick, thin, smooth, knurled.
South America too, right?

Well, sure. Adding many variables usually makes anything harder to do. But that generally just means it takes a little more effort.
Are your hands horribly mangled or something? Am I bringing up something hard for you to deal with?
Hands? It's horribly hard to fit my trunk into my pockets.
