@@furballscave4431 Please don't say the things you don't know. The man in this video is Daniel Kish. He met that boy (Ben) who also did this and passed away shortly after. Long poignant story. Daniel Kish said Ben had the strongest echolocation skill of anyone he ever met including himself. Ben could even sense chain link fences. A lot people around the neighborhood refused to believe he was blind. The neighbors would say _"I don't see him with a cane and instead I see that kid riding a bike avoiding obstacles, weaving around cars how can he be blind? don't screw with me."_ He was taken away because of retinoblastoma; only then after seeing the videos on KZbin people learn to accept that Ben was blind. I bet he could ride an electric motorized scooter if he was alive, that kid was very special and I doubt we ever going to see/hear another person as equal as him.

[@captaincracked4919]

This guy is the real life daredevil

[@deniedprosperity4144]

People underestimate the power of sound and hearing. I felt this as a kid, when I was behind a theater with a blindfold on. I was behind this veil, and every time I talked I hear a sound, a resonating one, I could picture exactly where it was coming from and what was happening based just on the acoustics. Whether it was people talking in the lobby, music playing on stage, or other noises backstage, I had a whole scene painted in my mind from audio alone. It was amazing how much information you can perceive just through listening. Ever since then, I've been fascinated by how we interpret the world through our sense of sound. There's so much packed into what reaches our ears. I think if more people paid attention to listening actively, they'd be surprised what they can discover about their surroundings and even other people just through picking up on the auditory details around them. This man, is telling the truth. You can train yourself to adjust to a certain degree of technique without feeling the need to just sit there and let yourself die out of boredom. I'm not blind, but everytime I walk, I close my eyes and everytime, i could picture what is beneath me, what type of vehicle is moving on the on other side of my ear, it is phenomenal. And if you think I walk at a few hundred meters, you'd be wrong. I know exactly what the layout of my hometown is therefore it makes it so much easier for me to simply walk all the way home without opening a single eye. The sound of my footsteps never stop echoing bottom to top, that I genuinely know what shape the ground is, a rocky upward slope, a straight but bumpy road, it made me realize that I have also honed a the technique this man uses.

[@mbsoysal87]

I have a theory on why clicking sound works for him. In engineering, in signals and systems topic to be more specific, there is a concept called "impulse response". Basically what you do is that you apply an impulse (an infinitely short pulse) to the system and see how the system responds to it. This way you can mathematically model the system. This person very cleverly figured that out with a clicking sound. He applies a short sound pulse and identifies the system around him. I think it helps that the hearing part of our brain can do a frequency analysis. This video brought me back to my signals and systems course days :)

[@sarenace]

Try it yourself for a while. Im sighted but I discovered the same trick as a kid.

Why not make a simple machine with very accurate clicks (exact same frequency of sound and of clicking at a higher precision than his mouth)

[@spiralzzz203]

isn't that just echolocation?

[@chenzenzo]

​@@spiralzzz203 it's literally just reactive response science. Throwing a ball at someone activates their catch/protect response. However this incredible unsighted man uses active echolocation the same way bat's do, but as a human being he's able to gather far more information through reason and logic.

[@ashrais]

It is said that a significant amount of brain power is dedicated to vision alone. Loss of vision significantly improves other senses, especially hearing.

[@Beeg_Boy]

They actually did a brain scan on this guy and some other echolocating blind folks and found that most of the parts of their brains that normally generate images from one’s eyes were active upon hearing recordings of their own clicking. So his brain presumably still generates images of the world around him just without light and color.

[@thatblindnerd5070]

Albert Guilmont I am blind myself. Firstly, it's called a cane, not a stick, but I'll give you the benefit of the doubt. Second, it is always important to use a cane even though you may have other techniques up your sleeve. Using a cane is the first and most fundamental aspect of being able to navigate the world as a blind person. It can tell you information that echo-locating can't always tell you.

[@dougiequick1]

I love this! Long ago before I knew of such blind folks using sonar I thought about ways to create devices so the blind could effectively see. My ideas have always been along the lines of using one's own skin as their visual monitor by some means of using a section of skin to represent the area directly in front a person and then by some means creating physical sensations that would represent objects and obstacles. Everything from as crude as a hundred tiny solenoids to perhaps direct electrical stimulous which would probably be better....with todays comuter processing and camera tech how hard could it be? What if a person simply wore headgear that produced a graphi "image" say on their forehead? Or if bald on top of their head even so the camera would scan in front and the computer would translate the image to the persons skin receptor grid updating every so many miliseconds ...I mean the ehco location method wonderful IF a person has the hearing for it but what I propose would work even for a deaf blind person ....it would simply be a matter of learning to intrepret the placement of the sensations....and of course the same individual could also have an ear piece with the computer describing the objects identity if not precisely as to what for common things then at least by shape size and color for anything else....such a system COULD also have a bonus system that reverts to sonar if it became truly too dark for the camera meaning a trained experienced operator could "see" better than ANY naturally sighted person in the dark. Are the devices such as this? I am pretty certain there has to be AI camera fed devices that audibly tell a user what a camera sees? Even with facial recognition to identify individual people and animals even I mean how could there not be THAT in this day and age...that kind of thing could keep telling a person they were clear to walk or when to stop too

[@dougiequick1]

WOW so easy to IMMEDIATELY witness one thing he said which is making a "shhhh" sound with a panel in front of him and being able to tell when the panel moves....lol you can do this simply making the sound with your hand in front of your mouth and then move your hand!
