This was a really amazing experience. I learned so much, not only about how blind people experience the world but about how I and all of us view so-called "disability". Thank you so much to Molly for doing this with me. Definitely go check out her channel!
Joe, thank you for this channel :D I have always been a fan of PBS but, even more a fan of learning. I love thus channel because you delve into such cool topics, but they are long enough to hold my attention span too. I struggle a bit because I can be very easily distracted but for some reason I tend to hang on and even want more. Thanks for another great video and for showing all of your viewers a world we are definitely not "seeing"
Hi I came here from Molly’s channel. Loved both the video on her page and this video. What I love most is there is no condescending at all. As someone who lost most of her sight three years ago (just before my 55th birthday) I totally love the science you brought to the table in both videos. Thank you. Now I need to try both passive and active echolocation (neither of which I’ve been taught). I’ve already noticed I get more from sound (beginning to recognise birds from their different songs when out on a walk). As my sight continues to deteriorate I’m going to need to develop new skills to remain independent.
This was truly SO fun! I can't wait to work with Bryan more to keep improving my active echolocation skills! I'll definitely be sharing my echolocation journey on my channel, so come hangout with me! Thanks for doing this with me, Joe!
I'm autistic, so I kind of do the same thing. Some of us feel uncomfortable looking someone in the eye. I'm more indifferent towards it. Whether I'm looking at you or looking somewhere else doesn't make much difference to me. But neurotypicals like it when you look them in the eye, so I try to remember to do that when I'm talking to them. Strangely enough, most animals consider looking them in the eye a threat. Try it with a chimp or a dog, and you could get bit or worse. So autistic people not liking it is not really that strange at all. Neurotypicals are actually the weird ones. Although that's true in most cases.
Blind people are sensitive to the direction the sound is coming from, so are perceptive to whether or not they are being projected at. Its their equivalent to making eye contact to communicate you are talking to that person
It’s amazing at 9:27 (it’s so overlooked) how when Joe lifts his hand and misses the bowl, Bryan WHO’S BLIND knows Joe’s mistake and corrects his mistake by moving his hand on the bowl.
@TheGhost I'm sorry if it wasn't clear that I was joking. I even left out the part where it would say "and go" because I thought it was too harsh. I just meant that the moral of this video is clearly that you don't need sight to experience the world, especially if you can use echolocation. I'm afraid I don't really understand your second point though. I get that you think vision is easier for you and gives you more information than echolocation, but I am pretty sure it still gives away your position when you are seen by others. And most humans don't have to fear predators in their day to day life.
Being fairly sensitive to this from childhood, I found that phrase to be interesting. For me, it's almost like an absolute void just existing in the middle of the miasma of noise. The closer someone is, the more absolute the void. However, it's about as clearly sensed as sound, so I get it. I just wouldn't have described it that way, so it was interesting
Hearing about how Molly was taught passive echolocation, helps explain how she is able to grab her drinks pretty easily, or know exactly where the handle of her fridge is, etc.
I think a lot of that is just spacial awareness. She knows her appartement so well by now that she can walk right up to the fridge and know where the handle is. And she knew where she placed her water bottle, so she can reach out for it and know that it's there.
she has a good chunk of her vision left, shes faking total blindness. ive seen her react to peoples movments in loud enviroments. she can clearly see something.
@@chrizero2319 what, you can't sense when someone who's close moves around you when you have your eyes shut or looking somewhere else? I've always been able to do that. We have more senses than just vision that help us reconstruct our environment, when are people going to understand that?
"Sound shadows" is actually something I've been aware of most of my life, but never knew was a special concept until someone came face to face with me while I was napping in highschool. There was the room's general noises, where I was pretty aware of where the groups of people were and vaguely aware of how many individuals were in each one, (something I just liked know for whatever reason), when suddenly the most obvious void of sound popped up directly in front of my face. When I asked what they were doing, they were surprised that I could tell despite having my eyes closed. A decade later, and I still listen for those voids in the room. Actually, it helps me multitask as hospital security because I can take my eyes off of people that are likely to elope and still know when they stand up or otherwise change... sound shape? The dead zone grows taller when they stand up, or grows wider if they're leaning out of their chair/bed. Much easier on a chair. In general, I try to rely on my sight as little as possible. First thing I did with my multitool was learn how to access the tool I wanted by feel and memory. I put things down with the intent of taking them even if my eyes are somewhere else. Heck, I have a severe dislike of checking for my wallet by hand, so I just flex my leg to see if I feel its shape. My point is that even being sighted, I dislike having to rely on the sense entirely. I had never considered honing onto a single, individual sound (type) as my wayfinder. I just kind of listen for the garbled miasma of noises for voids in it. This video has given me something else to practice on!
When blind kids have the good fortune to work with a kind and expert teacher, amazing transformations can happen! Unfortunately, there aren't enough great teachers, school programs, or real understanding by adults for blind kids.
"there's so much noise out there, we have to be able to filter out!" My ears must be working overtime they straight filter everything out. Deaf joke...I am deaf, not funny :) PS thanks for having good closed captions!
I'd like to inform you that my girlfriend and I love your comment. Both of us have sensory processing issues so we found the "your brain filters stuff out" sentence funny as well but for a different reason lol
z706 sorry if I’m mistaken but are you saying I’m not deaf?! Because I am I have been deaf/ hard of hearing since birth. I can talk but that’s because I had enough hearing to learn how to. Again sorry if that’s not what you meant I just can’t see any other way to read the comment.
Probably just a slip of the tongue and not meant to be taken literally. The concept of sight is taken for granted to the point that it's ingrained in language, and it's easy to say that you see when what you really mean is that you understand or more generally perceive something. Just another way that society as a whole is unconsciously biased in favor of those without disabilities.
Molly made a comment about this in a video - she still uses the expressions like "watch a video" or "I went to see my mom" because she's not going to change her language for her disability. I think it's in a "why people think I'm not blind' video, or something similar to that on her channel - if she 'saw' something, someone sighted in her life described it to her.
@@calebb.890 It's habitual. She was not always fully blind, so it's a habit from when she was visually impaired, but not fully blind, to look to where she hears the noise. She can also see some light.
Sorry and i am nor blind or so, but apperently its more like a rough change than the end of the world. There is no time for self pity. I guess enjoy your time and watch what you want to watch whewn you can. Be strong but if something is on your chest, talking is the best way to deal with that. The world is unfair, but thats no reason to let yourself down. And i mean it seriously to use your time while still seeing instead of sobbing in self pity, a bit is ok, but only a bit. Watch sone good cartoon or the sea or whatever for closure, when you can. Then you have some memories to treasure. I dont really know what to say because it must be difficult, dont give up on enjoying your life.
@@jonsnor4313 Thanks. I've already accepted my future. That's not what my comment was about. I've had what you'd call a very "interesting" life, resulting in complex PTSD. I just finished my treatment, and trust me - it's been 15 very intense months of adjusting to rather radical change. I would very much have liked to establish something resembling normal life before adapting to the next big change. That's why I felt the video was motivational. It lessened the feeling of "huge change coming." I'm FAR from sobbing in self pity, thankyouveryfuckingmuch. I found that a bit offensive. See, when you've really *fought* to survive PTSD without blowing your brains out, you tend to *not* wallow in self-pity.That sort of experience tends to make you a fighter. No, I got a list of things to do before I go blind. A piece of advice: If you don't know what to say, stop talking. Asking questions is fine, but read the room, man ;)
@@jonsnor4313 That's quite alright. Everybody has a backstory. Life experience. See when you get a larger diagnosis, like a neuromuscular disorder, PTSD, or blindness, or what have you... people have a way of telling you, to your face, who or what you are. Because everyone has ideas of what the "disease" means. That gets very condescending. See, I'm still me. I'm not my disease. If anything makes you feel different, handicapped, limited or what have you, it's when other people have these preconceived notions. You get judged on that, just like you get judged on your tattoos. Or gender. Or skin-colour. In short; Don't tell people who they are. It's quite alright to ask if you're curious though. Have a cool day, man :)
@@timan2039 Unless you live somewhere particularly remote, or your house is unusual in some way, "complete darkness" should still be bright enough to see outlines.
I found it so weird that Molly would sometimes while she was talking, turn to the camera and look right into it, she's very good at knowing where something or someone is its amazing
One of the thing I noticed is that Molly - being blind for (over) a decade now - is still very actively and specifically looking all around her. She actually looks at the people who are talking and even towards the camera. You really cannot see that she is blind. Very interesting. Especially when I think about people who have gone deaf - they usually will speak less and less clear over time.
I found that interesting too, looking at someone is such an important thing for socializing and i'd wager doing so helps her seem a lot more "normal" to others.
I havent seen the video with her, or read so much into the illness that she has. But it might also be because she still can see, but the images is very blurry or really off focus. Again, I dont know much about it or really have an idea how it feels to have it that kind of illness. It can also be what she had learned. Like the passiv echo
@@Danspy501st The only 'sight' she has left is light and shadow perception, this is how she can look at cameras etc. if they have bright lights behind them, they stand out.
Yes! I was super focused on that too. Along with head and eye movements, she also uses very subtle facial expressions I have almost never seen on a blind person before. I wonder if this is something she does intentionally because she is a youtuber, and therefore has to appeal visually to sighted people.
I actually used to do this as a kid when we played hide n seek in the dark. I'd keep replaying how the sound of their voices saying 'ready' felt on my ear drum and walk right to em.
she 100% wasn't blind, altho what they showed works, she wasn't blind and this is bs because of the normal abient noise around everywhere it would work so frequently
@@jeffgrill7214 how do you know she wasn't blind. My school teacher was legally blind but he could still see the difference between light and dark so he would close his eyes when doing things such as the party games we did (pin the tail on the donkey)
I think that was more her earth bending skills as well. Since she is able to actually move the ground she walks on and feel everything with her bending I think that gives her a much better perception of the world along with her echolocation.
Ok, I'm autistic and highly sensitive to sound and visuals. The moment Molly stood in the corner to try and create an image of the corner with echolocation, my brain just flooded with information. It was a similar sensation to when I would look someone straight in the eyes. You see, contrary to what many believe, autistics who avoid eye contact (not all do), do so not out of lack of social skills, but because the amount of information flooding in is too intense. It's disstressing. With Molly creating that image in the corner, a similar thing happened. I quickly paused the video, 'cause of the disstress I experienced, and to take a moment to process. It was highly uncomfortable. When I got through processing, I realised the image of that wall was lodged into my memory, like it imprinted. I can just recall it now. I'm not trying to be special or anything. This really happened, and it greatly unsettled me. So why share it? Because I'm always interested in the workings of the brain, and people watching videos like these might be as well. So I thought people might find it interesting what an autistic brain with sound and visual sensitivities might do with sensory information like this. First I thought I might want to learn echolocation, because I thought I would be great at it. Now I think it would be a horrible fit. It's just too much and too disstressing. It's really interesting to me though.
Thank you for taking the time to expound on you idiosyncratic experience with that particular event. I would love to learn more about your special disposition. Do you know what the official name is so I can read up on it by chance? I suspect that many people experience a flood of information during eye contact but may not realize or be able to quantify the phenomena.
No - DO learn how to do echolocation on your own. Visual information is so intense that its often helpful to me to just shut my eyes and navagate blind for a bit. Ditto when I focus my eyes on something highly detailed (like a textured wall) to tune out noise. Knowing what to do with all the information coming in is useful in making it less overwhelming. Like when I go 'dectective mode' in social situations and observe/process all the non-verbal signals coming in without talking or adding to the conversation myself. (Hint - looking at the space between the eyebrows is a good "cheat" to looking people in the eyes. It reads the same to them, but isn't as overwhellming to you) Learning to process and sort overwhellming stimuli is one of the best ways to deal with overload. (Be careful of getting "overtired" tho - although adult brains don't seem to have that problem the way child brains do)
I use both ears and feet. Sounds help me find vertical things and vibrations help me find things on the floor. Plus, as I'm walking, I can feel the exact type of ground underneath through, obviously the hardness, and and the vibration from the contact with the ground and my feet
Thank you. I'm having increasing difficulty with vision. I'm mostly tapping a finger ring or a ball bearing on my wheelchair to get the sound, as I can't really click my tounge well, but this is really useful, and validating, as so many people think I'm nuts if I try to explain I'm using sound to get an understanding of where I am. I'm autistic, and have always used sound to supplement vision, and have listened for the echo of my motor to hear whether I'm about to hit something for a few years now. But I never realised the fidelity I could get. 20 minutes practice and I could walk through a door without feeling for the frame first, now I'm doing so much more. I never thought I'd be able to locate things like this again. Thank you again.
@@tymmezinni same, i was playing videogames with the video in the background, and when I heard the name the first thing that came to mind was "VisionEars". Later I paused my game and happened to see the dudes shirt and I was disappointed.
I'm not blind, and I remember doing this in the family car when I was little, when we'd drive with the windows down in summer. I recall very clearly hearing a loud hiss that would periodically go completely away, then come back, then go away again, and wondering what was causing it. I kept listening and looking out the window to see what it was because it sounded like an echo -- and that's what it was. I realized that it was the hiss of the tire noise. When we were next to a curb, the hiss bounced back to the car. When we went past a curb cut or an intersection, the hiss went away. So I could close my eyes and tell when we were passing an intersection or curb cut by listening to the tire noise. Sighted people I think hear this more than we realize, but our eyes are so overwhelming a sense that we just tune it out -- but even we can tell things like how large a darkened room is when we walk into it.
It makes me cry to see them looking at each other even though they're blind... I'm so glad they are able to cope with the world in their own unique way. Life sure ain't fair but you gotta deal with what you got. I kiss you blind people and send tons of virtual hugs, I'm so proud of you🤗🤗🤗
While I appreciate the sentiment, I urge you to consider the fact that blindness is something that is adapted to. There are fates far worse; this idea is actually most harmful to blind children, because they learn that their livevs are difficult and eventually internalize it. It's also worth considering how different it is to close your eyes or put on a blindfold for a while; imagine speaking English, learning Spanish, and concluding that Spanish must be too difficult because you try to have a fluent conversation after a day. That's sort of the logic error I *see* sighted people make a lot (pun intended)
Im tearing over this. I never felt so inferior to a more handicapped individual. I hits me really hard on how much I have taken my body capacity for granted. On a less serious note, these 2 people can literally be a ninja.
When my family still uses CRT TV's I would use the high pitched humming from the TV to hear if someone is coming to my room... And now because my PC is always on I could listen to the fan sound to hear where I'm facing
That was an amazing video! I loved the insight… However, she did not appear to be blind in anyway, because she looked directly at everyone any time it was important. And every single second.
My grandma was blind and taught me this. She told me that sound is like waves around rocks, you can feel the shift in current. She used passive for most things but active if in a place she wasn’t familiar with. I now have very sensitive ears, i can hear things most wouldn’t and I notice small noises that most would ignore as background noise.
Retinitis Pigmentosa is a progressive disease that causes sight to gradually narrow, to gradually lose contrast, and then to gradually fade out. It sometimes takes years and years (I had a friend who went through it). I don't know what stage she was in at filming. Did the video say? She may have still been able to see light and shadow at the center of her vision, so closing her eyes would have put her fully in the dark.
You can do a version of this with someone who is deaf (depending on their type of hearing loss), you can use claps to get a deaf persons attention because of the way they pick up on vibrations. Its fascinating!
I went to a church dance with some friends who were deaf and there were balloons as decorations so the deaf people would lightly hold a balloon in their hands and the vibration of the music from the speakers would vibrate in the balloon and they'd be able to feel the music thru the balloon. As someone with hearing, I could feel the vibrations in the balloon as well, but it wasn't as profound for me as it was for my friends who were deaf.
Echolocation skills should be part of our curriculum starting from our elementary school. It is as important as learning how to swim and even more important than learning how to sing as echolocation is kind of a life saving skill that is very useful during the absence of light.
Ahh, no. No, that is not a good idea. Blind people who have lived with vision impairments have had time to learn how to compensate, learned ways to do things differently, putting on a blindfold for a week is similar to painting a white person black and believing they'll live the black person's experience.
I've been wanting to do something like that for a while and document the experience. Only problem is that I need a friend that I trust to be as aware and borderline paranoid of the area as I am before I'd be comfortable enough to actually work without too much hindrance
I would wanna do that but could it damage your eyes ? Not seing any light for a week. But if it doesn't damage eyes it could be a great way to understand or see a bit of blind persons life but idk
I don’t think it would damage your eye. You might see the world upside down for a while after taking your blindfold off though. I heard that’s what happens to people who live in caves and stuff like that. Your eye sees the world upside down and your brain flips it rightside up. Your brain has been doing this since you were a baby. But if you don’t get any visual stimuli for a while, your brain will forget this trick and you will have to relearn it. I don’t remember how long you have to be blindfolded before this happens though.
Apparently she can see dark and light (on her channel she mentions this), so it's probably distracting to her when she's trying to echolocate. Really interesting.
Happy Poop she’s legally blind .. imagine looking at the sun with your eyes closed if you put you hand in front you can tell it’s there just not where or what it is
I have actually experienced the passive echolocation or at least it seems like it. I have RP and so have limited vision at night. Yet I can usually tell when something is in front of me. I just never knew what it was or why it worked. Very interesting.
There is a "phenomenon" called blindsight. Basically, there is more than one part of the brain that processes visual stimuli. Some people who are effective blind due to damage to the part of the brain that processes vision consciously can still "see unconsciously." These people can determine that there are solid objects in their environment without being aware of it. This description is a VAST oversimplication though.
As a sighted person, I've always payed attention to sound. Comes with musical training, I guess. I just realized that I can already augment what I see with sound. It's really cool. The difference between hard and soft surfaces is amazing.
I have this habit of using a different glass to drink water every time i go to kitchen. And a lot of times my mom taking a bath shouts from the bathroom, exactly at the moment when i am about to pick a different clean glass, telling me to use the glass i used minutes ago or i will have to wash it. Beat this echolocation.
I've always had a sort of respect for "disabled" people, blind and deaf especially, but this just took it to a whole new level. I have a newfound respect for blind people, and deaf people a little too, and I hope to learn more about how people with sensory "loss" can actually gain more from it than any fully-sensed person could.
I've been a musician all my life and theres a lot of research on the neuropathways created, using every piece of your brain at once. So far, skilled musicians are the only ones known to activate everything. They even done very similar experiments using an MRI, which produced similar results. Anyways, just last night I realized that I could clearly tell what the cat was doing in the next room, using the sound of a fan but I didn't think much of it. Just the sound of air moving in a quiet place has done the trick, for quite a few years now. They are very accurate about the picture it paints, or I personally lfeel more like pinpointing things on a mental map without seeing it. After watching this video, I realize just how accurate it's been and how I've never even given it much thought. *I'd like to see a video about the neurologic effects that lifelong musicians experience.* You're alright with me Scientist.
I just found your channel through Molly's channel and am excited to watch more of your videos. I am legally blind and found both of the videos y'all did together to be very interesting. I don't have RP, I have Septo Optic-Dysplasia,but I can still relate to the info you shared about it. And I can't actively echolocate but hope to learn.
I have something called aphantasia (the blindness of the mind’s eye), which basically means that I am unable to visualize. This video made me super curious about echolocation, because the idea of creating a visual representation of anything is so entirely foreign to me. Do you think echolocation could still work for people like me, who lack the ability to create images with their brains?
It should work. Your aphantasia is more likely a lack of awareness of your brain doing the normal spatio-visiual processing that everyone else does. In a nutshell, as he said, the brain is hungry for information. Neurons feed off information, which they represent in the form of energy. They crave it. It hurts sometimes when you learn a lot or have a big epiphany, but that's growing pains. The neurons LOVE learning. So turns out, we can plug virtually any sensor OR motor into your brain and your brain *will* learn how to interpret/control it. This seems to be a general fact of all brains, and aphantasia should have no effect on it. You just won't see it as imagination, but simply as it is, whatever that means. It won't seem so weird once you're doing it.
I have aphantasia too! Basically, when I try to imagine things, it triggers the parts of my brain for words instead of images. Thinking of a horse for example, makes a list of what a horse is: a pretty big animal, with four legs, a round behind, eyes on the side of their side, pointy ears (and so on), but I don't see any of that. I can draw a horse, tho, because even if I can't see it in my head, I recognize what works and what doesn't on paper. I actually love drawing, because it's the only way for me to see what I imagine. I have complete aphantasia so I don't see anything, but some people can see colours, basic shapes or blurry things.
@@MrOuchiez It's fascinating even to me, I was mind blown when I realised I have this and people can actually "see" in their mind, I always thought it was a figure of speech... I hope they make videos on the subject on day!
That's fascinating stuff. My Uncle said he can't visualise stuff in his mind - he doesn't see objects/things - and yet he can do map grids... to the point where he could guide someone lost in Jasper national park over the radio for 20km, just by their descriptions of trees, rocks, road/path curves and whatever else they see. It's almost like his mind noted the quantities and shapes of objects that he had seen onto a mental grid for later use. For myself, I cook via sound. My nose doesn't have much sniffing power, but I have always listened for the various cooking phases and know exactly when to adjust temperature for a dish or meal. I also seem to have pretty good close up vision, and am especially observant of shinyness/reflectiveness. Years ago I formed a theory about how our subconscious and conscious minds work together. The subconscious is always active, handles the heavy load of living and most everything that we do - it processes immense amounts of sensory input so that our conscious mind doesn't get overwhelmed. It is very efficient. And yet... it is somewhat directed by our conscious mind. What is important to "us" tends to determine focus and where resources and effort are spent. Conscious processing takes a lot longer, but if something is important and you direct your thoughts there, it will become important for your subconscious too. If that's Facebook or American Idol, good luck picking up new skills. You might remember who performed what song on what date, but that's possibly less useful unless you love trivia or compete for money with it. If videos like this hook you in, you've got much better odds with both of your minds on the same page on new and interesting skills. *Very* good odds that you can pick them up with some effort and persistence and awareness. A few years back I stubbed my toe pretty badly while walking down the hall... then did it again a few days later, and finally again within a month. My toe started to click when I walked. The 4th stubbing annoyed me a lot. So I asked my subconscious a question while standing there in the dark with my throbbing toe. Yes, literally - I thought aloud: "What can I do or notice to stop hurting myself and getting mad, and making noise that wakes people up?" - after 10 or 15 seconds (or maybe several minutes) I realized that I could see the very faint reflections of light off metal surfaces in the dark. I could see where the tap in the bathroom was... a faint glint. And where metal doorknobs were for closets, and the metal accents at the end of banisters and stairs. Then my mind started to construct the objects that I knew were there and remembered (like closet doors) in the correct places based on these faint glints. Now I can walk around my home and "see" it even though I'm only seeing black with some optic nerve colour noise (like blurred photoshop "Noise") and some faint glints. I suppose that's what's missing in aphantasia - no mental reconstruction / visualisation? I'm not sure what that would be like. I've got pretty strong mental reconstruction - I can imagine objects, rotate them, infer details accurately, etc. Reading these posts/comments was intriguing... or rather, listening to myself read them was, since that is more accurate... I hear in my mind as I read. Yes, that limits how quickly I can read. I have no idea how people do speed reading? I can't absorb anything when I try to do that. And yet typically I only have to read stuff once to remember it for 6+ months... (very good short term memory) Hmm... I can't learn stuff while listening to music, either, or when there's lots of background noise like random TV - since then I can't hear myself. I need quiet and then it sinks in for a long time. Brains and quite neat, and apparently pretty different in how they process stuff!
Despite having decent eyesight, my hearing has always been highly sensitive and I think I’ve always naturally used it to get a better ‘read’ per se on my surroundings, especially if I was in a crowded area or an area that was hard to fully focus on when using just my eyes. It honestly saved me from bumping into people, things, and whatnot. But I’m amazed by how much I actually rely on my hearing to get an image of my surroundings. One of my favorite ways to use/practice this is if I’m at a book store or reading a book somewhere, I’ll focus on the sound around me so I can continue reading without too much interruption. That way I’m aware of my surroundings while not needing to be completely focused on it where it detracts from me reading. The sound often gives me a clear image of what’s around and though I still struggle with recognizing certain things immediately, and for the most part, I’m actually quite good at identifying everything around me well enough. Now that I think of it, the times I really struggled with knowing where my surroundings were, was in places where it was very loud and or hectic/hyper. The loud noise often threw me off and to some extent disoriented me, and I had a hard time keeping up in places that were hectic/hyper. It’s honestly amazing and most times people are absolutely amazed that I can hear that well. Especially since I have pretty decent eyesight. Though, there are some downsides to it too, it’s not too intense if you know what works best for you and what doesn’t. I enjoy quiet places but don’t mind getting out to a somewhat loud place every so often. It’s a balance I think you got to find for yourself. But that’s my thoughts on this. Great video, I loved it! (^ ^)
As a vision-impaired guy myself, I wish it wasn't quite so heavy on the "wow, blind people can do stuff too!" tone, but it helps show the world that we're not helpless and have our own means of doing things. So good on it. Anything to stem back the tide of ignorance when it comes to blind representation.
I've worked with several visual impared individuals and every one of them wished they had this ability. There is some ligitamacy in what they show, everyone can go and do the exact same thing they just showed. Then go try all of it and 3 feet away, now 4 feet away, then 5 or 10 or w/e.. you will quickly learn that after like 2 feet and your face isn't directly in it you have very little control over knowing the direction of the sound, at least enough to " human " echo locate
A mosquito just approached me in the dark while I watched this. I realized I knew exactly where it was directionally and in distance. Fascinating what can be accomplished when we don't accept the limits people put on us.
That was incredibly cool. I'm not blind. I'm nowhere near blind. I ~AM~ very light sensitive, to the point where I need special lenses to even try to function in normal light. I read about humans and echolocation a few years back and thought it was a really interesting thing. For the next month or so after that, I was constantly clicking at things while closing my eyes and trying to resolve the sounds with what I could see with my glasses. It was cool, but about the best I could do was figure out when I was about to hit a wall or if there was a large open space nearby (think a warehouse or field). This video, in 16 minutes, covered more than that month of playing around by simply giving examples and exercises that I just never thought to recognize. And that's amazing. I'm.... probably going to be clicking at work tomorrow..............again.
Just tested this myself and found that it's much harder for close things but immediately i could pick up the far echos from a corridor or far wall. I guess over time you pick up the very quick responses which would be the close up reflected sounds.
Nice, I love echolocation content! I had the opportunity to talk to Daniel Kish and see him echolocate once, he could describe so good the soarrounding, his mental map was so rich. He was able to detect a building behind another building from a sidewalk, including the metallic fence that was in front of him. The important thing he told me was he need the mobility cane anyways, cuz sometimes the are elements on the streets that you can't picked. I learn some concept today thanks to you video "active/pasive echocolation". Good to see Molly too.
No, spatial awareness localizes in a different place. AFAIK, primary visual cortex mostly recognizes (i.e. groups "pixels" and their changes into) shapes and movement
I have a sensitivity to light so my environment is very dark. I can navigate my entire dark house. Now, I know why. Passive echolocation must be what I'm picking up. This is so awesome. I'm going to try the active echolocation now. Wow, thanks for sharing.
Even though I don’t currently have any vision issues, I want to learn O&M because I think it will be helpful not just for myself but also for the people around me
Teacher: "Humans have five sense hearing, taste, touch, smell, sight" Me: "I can see using sound" Teacher: "You cant see using sounds silly" Me: *shows him this video* Teacher: "Wait. Thats illegal"
I once was a sighted guide for a college student taking ice skating lessons. Once of the things we do at the beginning and end of class is skate around the perimeter of the rink. The student could tell by the change in the quality of the sound when she was about a meter from the wall. I eventually got to the point I could hear the same change. The hardest part of the task was explaining kinetic motions statically. The move that was the hardest was flipping for skating forward to skating backward while maintaining the same vector. Lucky for us, she was an athlete with good body awareness that had also been sighted until her early teens. During the semester, we both managed to complete all tasks to the same standard as the rest of the students.
Frank Herbert wrote the first "Dune" novel in 1965. Some years later in a sequel, one carachter was inside a cavern with no lighting, she was so skilled at echolocation that she used a clap of her hands to measure the cavern within centimeters of precision, not being blind. Oue brain plasticity is awesome in real life too. There is a possibility I go blind in the near future because diabetic retina disease (I already loss the vision of my left eye), this is inspiring. Thanks for sharing.
I have issues with locating where sounds are so if someone is making a noise or trying to call for me, I won’t know where it’s coming from because I can’t filter out noise. But when it comes to smells they’re so strong and I really dislike it so I know where they are or things on my skin even if it’s small, but for some reason sounds are hard to locate. And when I close my eyes I can feel things near me even if they aren’t touching me and it’s so intense I don’t like the feeling so that’s why I don’t like navigating in the dark.
I am a singing teacher and work a lot trying to develop peoples' hearing. This is so very interesting to me. I am an echolator by nature, I always study the acoustic shape of every space.. comes from being a music producer I guess, listening and designing musical soundscapes. A great example of the value of multi-disciplinary study. Thank you for this.
Huh. You know I was super into Daredevil as a kid so I would often try my best to do things in the dark or even with my eyes closed, and I got really good at over the years. In fact it became a coping mechanism bc I'm autistic, so oftentimes I get sensory overload bc of "too much information", so if I cut out the primary sense (sight) the extra info from my other senses becomes useful instead of harmful. Didn't even realize that I'd been passively echolocating this whole time.... And that I taught myself???? I'd never even heard of passive echolocation, only active!! Neat!! (It's actually to the point that I end up becoming more clumsy when my hearing is blocked! Like I'm less aware of my surroundings and end up bumping into things and whatnot more! I mean autism almost always comes with dyspraxia, which is like... A disability on the sense of proprioception, so I guess my brain has been using passive echolocation to overcome it or something??? Idk. I mean I did used to be RIDICULOUSLY clumsy when I was younger..... Started getting better around the time I started with the Daredevil training as I often called it (just to myself, I didn't even tell other people about it), so... Hm. Maybe.)
@@delaneykeller1389 I believe It is from Avatar the last airbender, during the ember Island play they have the buff guy playing toph say a similar line and scream then saying the second line after lol
She's so beautiful. Side note my son was born blind but he would always look in the direction I was in even with me trying not to make noise it's like he knew everywhere I was and could pick me out of everyone in the room. I would make noises when using hose appliances and explain to him what they were an how they were used.
