Facebook improves for blind people to see images


Facebook has taken many initiatives in different fields like internet (internet.org) and social activities. Now they improve facebook for visual impaired people. As per estimation around 39 million people are blind and 246 million people suffer from severe visual impairment. They are unable to enjoy facebook where around 2 billion images gets uploaded everyday. So, blind people feel more frustrated as they are unable to participate in social engagements. Currently they have to depend on some one else who see and explain them.

Facebook is trying to create a technology which helps visual impaired people to enjoy facebook. They are introducing automatic alternative text. Automatic alternative text or automatic alt text is a new technology that generates image description in object recognition technology. It is based on artificial intelligence, neural network that has billions of parameters.

Currently, facebook provide a feature in iOS device for screen readers that if a people scroll the news feed and there is an image, he can hear the name of the person who has shared followed by the term 'photo'. There is no more description on it. Thanks to automatic alternative text method, where people can now know much more about images, eg. people can hear 'Image may contain three people, smiling, outdoors.' 

Facebook launches this feature first on iOS screen readers in English, after it they will add this feature to other language and platforms. It is available in U.S., U.K., Canada, Australia, and New Zealand. It takes around 10 months to bring this feature to its current stage through design, prototyping and user studies. 

It is very important step for visual impaired people who can now enjoy, laugh and share their moments on facebook as other normal people does.
