I’ve read about this feature somewhere before but still can’t figure how to
use/activate it. If it is supposed to work automatically, then it is not
working on my account. I use Facebook the mobile site and I wonder if this
could be the reason it is not working.
Best,
Amro

Identity 2016: Facebook lets blind people 'see' its photos
Visually impaired Facebook users try its new AI technology
As the internet becomes dominated by images, Facebook is launching a system
which can "read" photos and tell visually impaired people what appears in them.
The internet is changing. From a medium based almost entirely on text, it is
now becoming increasingly picture-led. An estimated 1.8 billion images are
uploaded every day to social networks such as Twitter, Instagram and Facebook.
Good news for aspiring photographers, bad news for blind or partially sighted
users who often have no way of telling what is in an image - despite the
available modern assistive technologies.
But a new service from Facebook, being launched on Tuesday, is attempting to
remedy that.

have worked on the new AI technology
Blind people use sophisticated navigation software called screenreaders to
make computers usable. They turn the contents of the screen into speech output
or braille. But they can only read text and can't "read" pictures.
Using artificial intelligence (AI), Facebook's servers can now decode and
describe images uploaded to the site and provide them in a form that can be
read out by a screenreader.
The man behind the development is Matt King, a Facebook engineer who lost his
sight as a result of retinitis pigmentosa - a condition which destroys the
light sensitive cells in the retina.
"On Facebook, a lot of what happens is extremely visual," King says. "And, as
somebody who's blind, you can really feel like you're left out of the
conversation, like you're on the outside."
The technology that King and his team have developed uses Facebook's in-house
object-recognition software to decipher what an image contains. It has been
trained to recognise items such as food and vehicles.

"Our artificial intelligence has advanced to the point where it's practical
for us to try to get computers to describe pictures in a meaningful way," King
says.
"This is in its very early stages, but it's helping us move in the direction
of that goal of including every single person who wants to participate in the
conversation."
The system currently describes images in fairly basic terms such as: "There
are two people in this image and they are smiling."
However, Facebook says it has now trained its software to recognise about 80
familiar objects, from cars and trains, to food and settings such as mountain,
water and beach, and sports such as tennis, swimming and golf. It adds the
descriptions as alternative text, or alt text, on each photo. The more images
it scans, the more sophisticated the software will become.
Last month, Twitter added a similar function which enables users to manually
add their own descriptive text to images. Although the descriptions may be
better, it requires users to actively choose to do it, whereas Facebook's new
system automatically tags every photo.

King and Facebook would like the system to go one step further and use face
recognition to identify people in a picture by name with help from their
database of users, but others are resisting the idea on privacy grounds.
For King, it is a matter of principle - he says sighted and visually-impaired
people should have equal access to the content posted online. Sighted people
know who is in many of the photos they see, so blind people should also be
allowed that same privilege, he believes.
"I feel I have a right to that information," he says. "I am asking for
information that is already available to other people to be revealed to me. So
I see it as a matter of fairness."
Jeff Wieland, head of the Facebook accessibility team, says the social
networking site is investing in accessibility and devising strategies for
different communities, to allow them to engage with it.
He says the site is "going to have dedicated teams thinking about how to get
all these different communities on-board and connecting with each other. That
is the chance for us to be equalisers and to really empower the world".

Service on 2 April as part of the Identity season. An edited version will be
broadcast as an Analysis documentary on BBC Radio 4.
