Daniel Kish: How I use sonar to navigate the world
Вставка
- Опубліковано 30 бер 2015
- Daniel Kish has been blind since he was 13 months old, but has learned to “see” using a form of echolocation. He clicks his tongue and sends out flashes of sound that bounce off surfaces in the environment and return to him, helping him to construct an understanding of the space around him. In a rousing talk, Kish demonstrates how this works and asks us to let go of our fear of the “dark unknown.”

Incredibly inspiring talk. Thank you.
This is actually quite an usefull skill, not just for the blind but for everyone who may sometimes walk in the dark. Loved tha talk!
💯
Blind people absolutely amaze me. This guy memorized his entire presentation without the ability to visually read any notes. Obviously their brains work much different than people with vision. It's just fascinating to me.
It's not that our brain works differently, I think anyone could memorize something if they really wanted to. It's all about looking at it from a different perspective. I have been blind my whole life. I've never been able to see anyone, and yet I know what the people in my life look like, even if I can't see them.
@@johndowlingjr. how are you able to type
Yeah, because he can't "read" Braille, I'm sure... lol
Gabriel Azevedo lmfao right?
this should answer some questions for those who are still confused. ua-cam.com/video/qDm7GiKra28/v-deo.html
After detached retinas in both eyes, trying to learn echolocation for future - he is right when he says the perception of blindness and the rest of society's attitudes is the biggest hurdle
I hope you succeeded
I'm sure that you already researched about it, but just to be sure, you know some retina detachment can be fixed with surgery, my dad had it and got it fixed, I just wanted to let you know, good luck
i know you'll probably not see this, but are you able to echolocate now?
@@isaquedopao6667 You really said "you'll probably not *see* this", didn't you?

There's another one. But he died.

Aaaaaaaaand?
DimasTVGaming Whaaaaat?
One of those "putting your life into perspective" talks. Funny guy, makes it so much easier to listen to.
I can see many tools developed to make this easier for blind children to learn early on, like an addition to learning to walk.
Rhyle there is some interesting stuff being developed aside from the obvious recreating of the eye there are a couple cool tools on the market already for example a device that picks up the color of something you are looking at and then creating a sound specific to that color value do enable colorblind people.
What i think will be interesting is what happens when we are able to give blind people visual sight and how that then functions when they have mastered sonar and how these 2 different ways of seeing the world interact.
Undead Bizkit As a person with sight, you can learn sonar and do what you just suggested - right now.
Sounds like he had good parents.
Yes he had I'm jealous
Yes.
Agreed

Same here.

Does this mean I should stop helping the disadvantaged?

What an absolutely incredible man that makes no excuses, asks for no consesions and totally blows my mind...

Okay
What an absolutely brilliant and fearless man. He is exactly how I would define mental grit.
One of the best Ted talks I’ve seen more about how to raise a child and how to love and look at life then the whole echolocation. He needs a podcast I could listen to him all day
I saw Daniel in action on the BBC America program "Wonderstruck" and had to investigate. It was amazing to see him riding a bike down a trail. I'm glad to know he has an organization to help others learn this amazing skill of echolocation. He's an eloquent speaker and explains things very well.
I have developed that skill somewhat. Hella useful. when i was 5-7 my neighbor was blind and he had many tricks. I would hang with him all the time and help him and he really changed my young life. Ernst Vorpagal was his name in Grafton, WI. He had lost his left eye completely, and his right was totally ruined. Happened when he was 19 in the military. They were wonderful people and he and I would listen to audiobooks and he would always make his wife blindfold me so I could see different. My first rational memories are in his apartment.
If you watch TED Talks, you learn that EVERYONE can teach you something.
Yes.
The only thing is, that these people are sharing their own subjective experiences.
And, those aren't always reliably true for everyone else.
An, "objective," education cannot be learned from absorbing subjective accounts.
You will only ever learn what's been proven true to that one particular person.
TED talks are great, but they are NO substitution for a basic, scientifically-based education.
And, just being able to distinguish between the two is fundamentally critical.
(Or critically fundamental lol either way.😂👍)
@@twstf8905 Yet that to is but only one from out of an unlimited number of perspectives.
Yes.
Or if you are blind like me and Daniel we listen to TED.
This is very neat, I had no idea human use of echolocation existed. It makes perfect sense and I feel a bit ignorant for not figuring as much sooner. Much thanks to Mr. Daniel Kish for a very informative and interesting talk! I feel all the wiser regarding human blindness.
It can all be skipped. Blindfolded children quickly learn to see with their third eye. And it's in COLOR. So not about echolocation. The blind and the old can also learn. It's a matter of what we allow ourselves to achieve, the mind is the limitation. Just look up the videos of blindfolded children and adults. Able to see. Not tricked.
I am hearing impaired in my left ear due to my eardrum puncturing when I was young. (however, I was born with hypersensitive hearing, so it isn't very bad.) but I have insanely good hearing in my right ear, I can hear the whirs of old TV's and florescent lights (yes they make a sound) And I have trained myself to use a rudimentary form of echolocation to detect where obstacles or walls/ceilings are with my eyes closed. It is handy when it is midnight and all the lights are off and you need a glass of water.
The fact that you have less working ears than normal people yet exceed their ability to hear is really interesting!
Me, but my other ear still works. Those electric sounds are the worst tbh.
Doesn't everyone hear fluorescent lights though?
@@samvannoyen713 Yeah, I hear them too
Oh my a mosquito in your room must be terrible. Pisses me off enough already flying by my head with average hearing.
as someone who is blind and lost their sight at 12 I can tell you this guy is right. I'm meeting him in person next week. yes not being able to physically see is an issue to overcome. however it is easy to deal with sightloss than it is with perception. most blind people stop suffering that their sight is gone relatively quickly after the vision goes. the suffering continues because people think we can't do anything when we can. ignorance causes suffering, not blindness. don't ever underestimate the humanbodys ability to adapt and survive in the face of adversity. it's exactly that which makes us the dominant animalon the planet

This is my favorite ted talk in years
One of the most inspiring and interesting ted talk, i've been coming back here again and again for weeks... this is very interesting
Lol I remember discovering this when i was s kid. I used to like to click my tongue when i was younger, and eventually realised my clicks sounded different when I was near an object. Years later, I realised I was echolocating. Im obviously not good at it like he is, but I can close my eyes and tell if im about to run into a wall, or how large a room is. You can sorta hear the emptiness of a large room, your click sounds softer.
Very good.
But can actually see tge mapping the sound makes
@@johnrambo4603 No not at all. Not like him. Im sighted and havent had practice. There is also a blind spot when you get really close to a wall- the echo arrives at about the same time as the sound of the click does from your throat, so it sort of just sounds the same.
I actually did some research into bats echolocating, and found that bats ears disconnect when they send out a chirp and reconnect a microsecond later. If my ears could do that it would be wayyy easier. That way im only hearing the echo itself, and not my own clicking. It also turns out that high pitched sounds allow you to hear more detail, so i tried sending out a whistle, but I couldnt get anything. Could be lack of practice.
@@johnrambo4603 a sighted person will generally need to close their eyes and allow time for their ears to attune to their own clicking it's slow but can be done
What a great talk. What a smart man......love this.
For all of you thinking this sounds "sketchy," do me a favor. Rap on a couple of different objects with different densities as your eyes are closed. These objects could be the back of your phone and the table in front of you. Now, think really hard about those sounds, taste the differences between them, and from these differences form visual amalgamations from all of the childlike blobs in the depths of your mind, all with your eyes still closed.
That is how this man sees, and it actually seems like a lot of fun.
Dudes legitimately got a superpower. Thats incredible.
Pure humbelness, beautiful words
Finally, back to the TED I love!
Very well spoken indeed. Interesting ideas.
Now that IS really inspirational!
Unbelievably great stuff, congrats!!
Great man and Great Mind
Thank you. I wish I would learn this skill in the near future.
the views are so underrated for such a valuable perspective
Not any words I can think up to describe this man. I know my common sense tells me he on purpose or not has developed his hearing to be much greater than most of us. Super impressed here.😉
this guy will never judge by what he sees... that is one kind of a gift.
Brilliant talk. Awesome.
Mr Kish thank you
for giving me the chance to hear you and enlightened my thoughts hoping now to enlighten my one blind eye Thanks again Sir.

his attitude on life is amazing. much appreciated TED
He is so cooool man!! Thank you for teaching me science man.
Imagine playing hide and seek with him, would it be easier or harder to hide? Assuming you make no loud noise or movement.
I would say that it depends on the distance and place of the play area. If it's a medium/small enclosed area, it would be harder for you (because he needs his own sound to "bounce" back to him to locate).
@@guycrimson4095 he will hear your breathing and every movement, around corners, through bushes, in complete darkness and in bright light.

@@lyingonthemoon792 are we gonna ignore eco lactation?
@@vrabiealexandru2755 def going to r/boneappletea
Every child should spend a day (or month, possibly a year (edit)) blind or deaf... this would improve sensory awareness and also respect/understanding for those considered 'less capable '... in feudal Japan... blind people (in some instances) became masseurs because it was believed that they had a better sense of touch... this talk... seated me and has resulted in the questioning of reality.
The problem is that a visual system is very sensitive to changes and inactivity. I seem to recall a cruel 'experiment' on a kitten(s?) that was kept in the dark and even after the blindfold was lifted after some time, never learned to see.
David Eagleman (who has a great TED talk himself) has a theory that we dream to keep our visual system going or it will be quite quickly taken over by the other brain systems.
@@katarinajanoskova I work with someone who's daughter is practically blind in one eye, took 5 years or so for anyone to notice, she has to wear an eye patch regularly in (the hope) order to correct the issue. I hear what you're saying tho. Valid point. What're your thoughts on requiring all children learning 1st Aid in order to finish primary school? Also, lifesaving to finish high-school (or middle school, I don't know where you grew up / live). Again, you make a valid point. Respect.
THANKS YOU VERY MUCH FOR YOUR POWER!
Уважение таким людям! Мы тут здоровые плачем, некоторые. Этот человек учит ценить жизнь..
inspiring talk, really great speaker :) .
This men is just amazing
His final words during the presentation, after he was questioned about his inner world, reminded me of The Last of Us. Not because of the Clickers, but because of the X-Ray-like vision/hearing you have to navigate in the game and avoid enemies.
We love you Daniel Kish
I'm so late, but I love this man.
So I haven't done what Daniel does and I'm sighted but for many years I have walked around my apartments at night effectively blind and realized a long time ago that I could hear where walls were. Of course things on the floor and tables, etc are an issue but at least I don't run into the walls by accident. I've found that there's always ambient noise and that I could hear the shift when I approach walls.
Fantástico. Mi nieto es ciego quisiera saber dónde llevarlo para que aprenda la ecolocación.
Amazing.
Very inspiring speech. The beginnings struck me real hard.
Fascinating
he has more eye contact with the audience than me in a class presentation
i have always said that if i go blind i dont want to live anymore, but now im not so sure tbh:p
True story.
FTWofc Sight is definitely the last sense I would want to lose as well.
FTWofc I think not hearing would be much more separating than being blind. I can't imagine not being able to listen to music, videos, people, or even the instruments I love playing.
Stephan Ainley True, but it is much easier to retain your independence having your vision over having your sight. I guess it depends on what you value most.
Not being able to taste the food I eat would be the my worst nightmare.
There's always hope.
素晴らしい動画を有り難う。
Amazing ❤
今まで見たyoutubeの動画の中で最も有意義なものだった
An amazing man ^^
why not make a wearable app that emits a much more piercing tone and transmits a version recording with heightened extremes in tone to help blind people out more with their sonar? could be a single earbud type device
I like that idea!
An adjustable sound generator. It might drive people around insane as the sounds aren't always needed tho 😜
That is a great Idea and it will develop to unimaginable depths once our ignorant scientists and medical researchers all come together and 100% support this and actually care. But more importantly, unfortunately as well, there has to be a huge profit ability for big medical companies and science to come together to develop something that can be put in their ears and will actually drastically distinguish different sounds, give feedback on how far they are, which direction, frequency, and help the blind develop a much clearer image of everything around them. But I don't see the profit margin for a business oriented society. Just not enough blind people able to pay for the research that takes 100's of millions in addition to developing the product so its affordable WITHOUT the state to pay for it all and the state does not care to have another expense of a very small minority. Prob the smallest one in relation to ethnic problems. So no money = no progress sadly and the bling will be left limited to a FUZZY image at best and with a long stick they can somewhat live a decent life. But they could drive cars, fly planes etc...just the necessary tools are needed. Too expensive and city wide sound reflectors would be needed as well so they would know where the stop signs are and exactly when it is about to turn red, speed limit, actual lane space, their speed, cars in front and behind that is almost solved) line deviation warning and automatic speed control lets a car stop and go again on its own based on the cars ahead of them and will shake the wheel if your car even leans on the line of the other lane next to you and will alarm if you come close to a car next to you. But all of that, in addition to their earpiece technology, can be made to make the blind live a pretty normal life like everyone else. Just the profit is not there and the cost is wayyyyyyyyyyyyyyyyyyy too high and has no return. Cruel business oriented society but its the truth...great idea though.
it is still not practical for it will just annoy other people. Our brain is already equipped to use Sonar for navigation, we just take it for granted due to the fact that we use our eyes more. the best thing to do is to invent an amplifier for the ears to hear clearly.
This won't work as good as using the mouth. The problem here is that you have to hear the sound when it is created. As early as possible. And i think that if you use your mouth to do it you even know that the sound WILL come before it actually does and you have much more feedback from all over your head.
@F. Exprt
You are delusional. Go take your conspirancy theorys somewhere else. ITs true that huge profit helps to establish proper science funding but even with out it they can get funding. This trhing we are talking about is not as easy as you think. The brain already does a GREAT job. The only next step would be to outsource that brainpower into a device and then send the correct visual information to the brain. Good luck in doing that.
I think shinjiprofiles comment has the best short term solution. Better hearing will improve it.
Why not teach kids independent mobility techniques so they're not beholden to technology or other people to live their lives?
LET'S NOT FORGET ABOUT "The Boy Who Sees Without Eyes' about the truly amazing Ben Underwood who, having lost his eyes at an early age, uses echo location to navigate".
First time I hearr about this was from a black kid who lost both eyes from birth and he naturally learned. It. Sad that the kid died from cancer years after making headlines on the news.
Sorry, I know that he isnt the only one.
Even so. Wisdom is brilliant!
Although I can see his point of blindness and how people think of it being so debilitating, although he has proved himself wrong in that point, because he has circumnavigated the obstacle of not being able to sense his surroundings, he is visually blind, yet he is not truly blind. The point at the beginning still stands, the stigma of blindness.
If we can use a radio wave transmitter and a converter to sound waves, may be we can improve their resolution..
would it be possible to create a sonar headset for blind people that constantly emits sound at a frequency above human hearing range (so as not to get irritating to bystanders) shift the frequency down to make it audible to help these people see?
This guy is awesome
that guy is amazing
I gather that the amplified sound in the venue made it a little too "bright" in the room for him to see well. Blinding-sound for him, blinding-light for the sighted. I, unfortunately, have a rather tough case of tinnitus. I wonder if that would render me blind in the echolocation world?
good daniel kish !!
헐 한국자막 진짜 너무 감사드려요ㅜㅜㅠㅠ♥
I feel all of us have this skill but not to the degree of him, I mean whole listening to this I made my bed, and I can hear where my phone was, I had also went under my desk but knew it was above it, I guess that’s when he meant by seeing around corners, and objects.
エコーロケーションマジですげぇ

From Luk global with love 😢
this is the real Daredevil , so inspiring
12:19 If I was in the audience I would whisper "Your amazing"
I would like to learn that, maybe one day I shall.
Absolutely amazing. I wonder if he would benefit even more so by some sort of sophisticated device designed to emit specialized sounds designed for echo location. Maybe it could have a few different sounds, some for wider general broadcast and some for more focused. Like he could blast a room with the wide one to get a rough mental 3D map, then hit all the objects individually with the focused one to get more detail.
I'm thinking if he worked with some engineers he could make something AMAZING. Maybe even something that any blind person could easily learn to use. Of course we would all have to get used to a bunch of people playing electric clicks everywhere they went, but I'm sure we would all be thrilled to see blind people with more mobility and confidence.
If you are smart and you're reading this... can you please make it? I'm sure it will only take a decade or so. :)
Money for such research and the products needed are millions at least and blind people just cant afford to even start a research yet alone do It for a long time and develop a product of sorts.
@@FExprt Even more so when you consider how unlikely it is for bling people to buy it because probably it will be very expensive at the start and if they search information about it they will find out they can do it themselves, even if not so perfectly, with no monetary cost.
I have retinopathy and my eyes still work but have slowly been getting worse is it worth learning how to navigate blind if you can still see?
太有意思了，新的视角带来新的世界，人的潜力真的是无穷的啊。
You make patterns in the brain when after training, whatever you do. After a while, you just know that the ceiling above you is 10 feet high or that there's a some sort of car in front of you because of how the sound reflects of the car's metal surface.
It is like this: How do you know how fast a car heading towards you is going by looking at it for less than a second? It is because you've trained your brain (sort of simply by growing up in a "kinda" normal environment) to calculate speeds by seeing with your two eyes. Eventually it ia completely hardwires into you and that is how reflexes work. Once you learn to bike you never forget, sort of.
Is there such a thing as computed ultra sound echo location belts for blind?
All humans can echolocate.
And each person doing it use own sounds and own mouth. Which is probably most important thing.
Why?
If there would be more than one source of given sound it will create problems. Also humans, like most animals, are constantly aware of own body position no matter what(well other that some illness)
If it would be not easily on go modifiable. It would create problems. Cause there might be symilar sound.
If person create own sound. They cannot be mistaken by that person. Because firstly sound will go trought bones to ears and be heard and only later it will bounce by surrounding and be heard. As such its possible to know difference in time aka position if objects. Allowing actual echolocation.

Wow
Does this mean humans can "see" Sound? Frequencies? Vibrations? Using high pitch clicks to bounce off objects around us, painting pictures of surfaces, edges, ridges, anything sound can interact with? I heard we do the same to see? Our eyes interact with our surrounding somehow ? Is our brain more capable then we think. I'm starting to question :/ so much right now
