- Hello, this is 6 Minute English from BBC Learning English.
- I'm Neil. And I'm Georgina.
- What do Homer, Ray Charles and Jorge Borges all have in common, Georgina?
- So that's the ancient Greek poet Homer, American singer Ray Charles and Argentine writer Jorge Luis Borges.
- I can't see much in common there, Neil.
- Well, the answer is that they were all blind.
- Ah, but that obviously didn't hold them back.
- I mean, they were some of the greatest artists ever.
- Right, but I wonder how easy they would find it living and working in the modern world.
- Blind people can use a guide dog or a white cane to help them move around.
- Yes, but a white cane is hardly advanced technology.
- Recently, smartphone apps have been invented which dramatically improved the lives of blind people around the world.
- In this programme on blindness in the digital age, we'll be looking at some of these inventions, known collectively as assistive technology.
- That's any software or equipment that helps people work around their disabilities or challenges.
- But first, it's time for my quiz question, Georgina.
- In 1842, a technique of using fingers to feel printed raised dots was invented, which allowed blind people to read.
- But who invented it? Was it A.
- Margaret Walker? B Louis Braille or C Samuel Morse?
- I've heard of Morse code but that wouldn't help blind people read, so I think it's B Louis Braille.
- OK Georgina, we'll find out the answer at the end of the programme.
- One remarkable feature of the latest assistive technology is its practicality.
- Smartphone apps like Be My Eyes allow blind users to find lost keys, cross busy roads and even colour match their clothes.
- Brian Mwenda is CEO of a Kenyan company developing this kind of technology.
- Here he explains to BBC World Service programme Digital Planet how his devices seek to enhance, not replace, the traditional white cane.
- The device is very compatible with any kind of white cane.
- So once you clip it onto any white cane, it works perfectly to detect the obstacles in front of you and it relies on echolocation.
- So echolocation is the same technology used by bats and dolphins to detect prey and obstacles and all that.
- You send out a sound pulse and then once it bounces off an obstacle, you can tell how far the obstacle is.
- When attached to a white cane, the digital device, called Sixth Sense, can detect obstacles – objects which block your way, making it difficult for you to move forward.
- Sixth Sense works using echolocation.
- a kind of ultrasound like that used by bats who send out sound waves which bounce off surrounding objects.
- The returning echoes show where these objects are located.
- Some of the assistive apps are so smart they can even tell what kind of object is coming up ahead, be it a friend, a shop door or a speeding car.
- I guess being able to move around confidently really boosts people's independence.
- Absolutely, and it's challenging stereotypes around blindness too.
- Blogger Fern Lullum, who is blind herself, uses assistive apps every day.
- Here she is talking to BBC World Service's Digital Planet.
- I think the more that society sees blind people in the community, at work, in relationships, it does help to tackle all of these stereotypes.
- It helps people to see...
- blind and visually impaired people in a whole new way and it just normalises disability.
- That's what we need. We need to see people just getting on with their life and doing it and then people won't see it as such a big deal anymore.
- It'll just be the ordinary.
- Fern distinguishes between people who are blind or unable to see and those who are visually impaired experience a decreased ability to see.
- Assistive tech helps blind people lead normal, independent lives within their local communities.
- Fern hopes that this will help normalise disability – treat something as normal which has not been accepted as normal before.
- So, being blind doesn't have to be a big deal – an informal way to say something is not a serious problem.
- Just keep your eyes closed for a minute and try moving around the room – you'll soon see how difficult it is and how life-changing this technology can be.
- Being able to read books must also open up a world of imagination.
- So, what was the answer to your quiz question, Neil?
- Ah yes, I asked Georgina who invented the system of reading where fingertips are used to feel patterns of printed raised dots.
- What did you say, Georgina?
- I thought it was B, Louis Braille.
- Which was, of course, the correct answer.
- Well done, Georgina. Louis Braille, the inventor of a reading system which is known worldwide simply as Braille.
- I suppose Braille is an early example of assistive technology – systems and equipment that assist people with disabilities to perform everyday functions.
- Let's recap the rest of the vocabulary, Neil.
- OK. An obstacle is an object that is in your way and blocks your movement.
- Some assisted technology works using echolocation – a system of ultrasound detection used by bats.
- Being blind is different from being visually impaired.
- having a decreased ability to see, whether disabling or not.
- And finally, the hope is that assistive phone apps can help normalise disability, change the perception of something into being accepted as normal.
- So that disability is no longer a big deal, not a big problem.
- That's all for this programme but join us again soon at 6 Minute English.

- Don't forget, we also have an app you can download for free from the app stores.
- And of course, we are all over social media.
- So come on over and say hi. Goodbye for now. Bye.
