A Blind Teacher Using Echolocation to Navigate the World

Echo is a fascinating and poignant short film about Daniel Kish, a blind man who uses echolocation to move about in the world and teaches others how to do the same. Using clicks, he and his students can go on hikes, ride bikes, and skateboard down the sidewalk.

If I click at a surface, it answers back. It’s like asking a question: what are you and where are you? I can get through echolocation a really rich, palpable, satisfying, 3-dimensional, fuzzy geometry.

The filmmakers worked with Kish to record the sound as a person would hear it in real life and make visualizations to help us see what Kish is hearing.

During the early production stages of the filmmakers Ben Wolin and Michael Minahan’s short documentary, “Echo,” they wanted their audience to understand what this skill truly meant. They worked closely with Daniel, a self-described audiophile, to record sound for the documentary through a special microphone that works similarly to a pair of human ears — a tool that Daniel also uses for teaching. “You record the audio like you would hear it,” Minahan told me. Because of this process, the sound design and auditory experience has a vivid, spatial quality that’s rare with a film of this scale. The gears on Daniel’s bike creak and whine with a closeness that makes it feel like we’re riding right next to him, while dogs bark, wind blows, and cars pass in the background. It’s through these rich sounds that we’re immersed in and transported to Daniel’s world.

Make some time for this short film…it’s really great.

Out of Sight

After her guide dog runs off after a thief who takes her bag, a girl navigates a world guided by her powerful senses of touch, hearing, and smell. Super charming and inventive. From the YouTube comments:

For those who don’t know, blind people will clap their hands and listen for the echo to get a sense of how big a space they are in, if it’s wide open or a tightly enclosed space.

A Free Hyperlegible Typeface from the Braille Institute

Sample letterforms from Atkinson Hyperlegible, a free typeface to aid readability for people with low vision

Atkinson Hyperlegible is a free typeface developed by the Braille Institute and Applied Design Works that makes text more readable for people with low vision.

“People may be surprised that the vast majority of the students who come to Braille Institute have some degree of vision,” says Sandy Shin, the institute’s vice president for marketing and communications. “They’re not 100% blind.”

Thus, most of the Braille Institute’s 37,000 clients across Southern California don’t depend on the dot-based Braille language. Instead, they rely on spoken-word tools and accessibility standards that encourage text publishers to think more carefully about the legibility of words on pages.

As you can see in the graphic above (taken from their summary PDF), Atkinson Hyperlegible’s letterforms are constructed so that each letter is as distinctive as possible so that it’s recognizable even when blurry or distorted by low vision. You can download Atkinson Hyperlegible on the Braille Institute site. (via print)


The Blind Skateboarder

Dan Mancina has lost 95% of his eyesight but that hasn’t kept him from skating. Red Bull has an interview with Mancina, who stopped skating for a couple of years after he went blind, thinking that it wasn’t something a blind person would or could do.

There wasn’t a defining moment that changed my mind as to what a blind person was, but the day I started to build that bench sort of started it, and sparked this passion and stoked this urge to skate again.

Seeing how people responded to that, that’s the shit I was searching for. To see me not as a blind person, but as a normal person, a skater.

Ever since I was seven, that’s who I was. I am a skateboarder, I just lost it for a while. I bought into people’s ideas of me and what a blind person is, and really I should’ve been searching for who I was and what I wanted to do.

People who are really good at something talk about doing it “by feel” or being able to do it “in their sleep”. Mancina’s skating ability is a good reminder that after you pass a certain threshold of expertise, so much of athleticism is just your body’s ability to unconsciously perform.

You can watch more of Mancina’s skating on his Instagram account.


How blind people use iPhones with VoiceOver

In a short video and accompanying article, David Pogue profiles a little known but highly useful iOS feature called VoiceOver, which helps visually impaired people do anything and everything on their iPhones.

A few years ago, backstage at a conference, I spotted a blind woman using her phone. The phone was speaking everything her finger touched on the screen, allowing her to tear through her apps. My jaw hit the floor. After years of practice, she had cranked the voice’s speed so high, I couldn’t understand a word it was saying.

And here’s the kicker: She could do all of this with the screen turned off. Her phone’s battery lasted forever.

It’s possible that people using VoiceOver to control their phones are more efficient at many tasks than those who use the default interface.

This was very cool: “If I’m in my office and put my headphones on, I’m hearing the phone call and I’m hearing what VoiceOver is saying, all through the headphones. But the person on the other end cannot hear any of the VoiceOver stuff. You don’t know what I’m reading, what I’m doing. I can do all these complicated things without you hearing it. That’s what’s really incredible. If you and I were working together on a three-way call, and you were to text me, ‘Let’s wrap this up’ or ‘Don’t bring that up on this call’-I would know, but the other guy wouldn’t hear it.

Joe showed me how he takes photos. As he holds up the iPhone, VoiceOver tells him what he’s seeing: “One face. Centered. Focus lock,” and so on. Later, as he’s reviewing his photos in the Camera Roll, VoiceOver once again tells him what he’s looking at: “One face; slightly blurry.”

The colors of friendship

When Ashley was a kid, she was legally blind. Her friends and family described colors to her in a wonderful way.

Yellow. I didn’t touch anything for this, they just told me that whenever you laugh so hard you can’t stop, that that happiness is what yellow looks like.

Green. I held soft leaves and wet grass. They told me green felt like life. To this day it is still very much my favorite color.

I love this list. (thx, nicholas)


The legally blind astronomer

Tim Doucette is a legally blind astronomer. A pair of surgeries when he was younger to help improve his vision left him with a superpower: because his pupils were permanently dilated, he could see in the dark better than other people. He built an observatory and with the aid of his telescope, he can see details of far-off stars and nebula that no one else can, including UV and infrared light.


The Shadow in the Darkness

Meet Joe Bollard. Joe lost his eyesight at the age of 2. In this video, he talks about his experience of being blind and the great difference having a guide dog has made in his life.

How blind people use Instagram

Tommy Edison shows how he uses Instagram on the iPhone.

So we’ll just take a picture of the crew. Why I’m holding the thing up to my face like I can look through the thing is beyond me, but here we go.

An Atlas for the Blind

The Atlas of the United States Printed for the Use of the Blind, published in 1837 before Braille was widely used, used embossed printing of lines, words, and symbols to be finger-readable.

Atlas For The Blind

Without a drop of ink in the book, the text and maps in this extraordinary atlas were embossed heavy paper with letters, lines, and symbols. To the best of our knowledge, this is the first atlas produced for the blind to read without the assistance of a sighted person. Braille was invented by 1825, but was not widely used until later. It represented letters well, but could not represent shapes and cartographic features.

A blind man’s first experience with echolocation

Austin Seraphin, who you may remember from his review of the iPhone, recently learned how to use echolocation to navigate his physical environment in a new way.

We started out in the hallway outside of my condo. They turned an old school into lofts, so the hallways and stairwells look and sound like a school. He had me walk down the hallway without touching the walls by using echolocation. Just to make it clear: echolocation does not normally replace the use of a cane, but for this exercise I did not use a cane. I could hear the hard surfaces, and gradually the walls came into focus. I could actually do it. The walls provided the shoreline, and I could actually see them on either side and keep in the center.

I began to understand that this required a whole new way of thinking. Justin gave constant instruction to help me learn. “Scan left. Scan right. Now scan straight ahead. You have to start thinking like a sighted person.” In deed, the muscles in the back of my neck would start to hurt because I did not need to move my head as much before. Now the direction of my gaze actually meant something.

We then journeyed to the stairwell. Now I would really begin to understand what thinking like a sighted person really meant. I scanned left, and saw a set of stairs going up like I had in my loft. I scanned right, and saw a set of stairs going down, which made sense. I scanned up, and saw something extend above and going back. What the hell? It took a minute to realize with Justin’s help that I saw the set of steps above me on another stairway. I had never experienced that kind of vivid three dimensional emersion before. My brain flipped.

Stem cells to aid the blind

Clinical trials are about to begin where embryonic stem cells will be injected into the eyes of people with Stargardt’s macular degeneration.

Robert Lanza, the company’s chief scientific officer, said that the first patient could receive the stem cell transplants early in the new year and although the trial is designed primarily to assess safety, the first signs of visual improvement may be apparent within weeks. “Talking to the clinicians, we could see something in six weeks, that’s when we think we may see some improvements. It really depends on individual patients but that’s a reasonable time frame when something may start to happen,” Dr Lanza said.


iPhone: a revolutionary device for the blind

A blind man buys an iPhone and it changes his life.

The other night, however, a very amazing thing happened. I downloaded an app called Color ID. It uses the iPhone’s camera, and speaks names of colors. It must use a table, because each color has an identifier made up of 6 hexadecimal digits. This puts the total at 16777216 colors, and I believe it. Some of them have very surreal names, such as Atomic Orange, Cosmic, Hippie Green, Opium, and Black-White. These names in combination with what feels like a rise in serotonin levels makes for a very psychedelic experience.

I have never experienced this before in my life. I can see some light and color, but just in blurs, and objects don’t really have a color, just light sources. When I first tried it at three o’clock in the morning, I couldn’t figure out why it just reported black. After realizing that the screen curtain also disables the camera, I turned it off, but it still have very dark colors. Then I remembered that you actually need light to see, and it probably couldn’t see much at night. I thought about light sources, and my interview I did for Get Lamp. First, I saw one of my beautiful salt lamps in its various shades of orange, another with its pink and rose colors, and the third kind in glowing pink and red.. I felt stunned.
