It has been said that adding an image to your post in social media is a good way to get more people to look at it. People who are blind or visually impaired might not be able to see those photos. Facebook and Twitter have made changes that are designed to make the images more accessible.
Facebook posted a blog that explains the change they are making. “With more than 39 million people who are blind, and over 246 million who have a severe visual impairment, many people feel excluded from the conversation around photos on Facebook. We want to build technology that helps the blind community experience Facebook the same way that others enjoy it.”
Facebook has introduced something called automatic alternative text. It generates a description of a photo using advancements in photo recognition technology. People who use screen readers on iOS devices will hear a list of items a photo may contain as they swipe past photos on Facebook. The change is a big one. Facebook states that before, the screen reader would describe a photo as “photo”. Now, the screen reader might say something like “image may contain three people, smiling, outdoors.”
This change was made possible due to Facebook’s object recognition technology. Facebook has launched automatic alt text on iOS screen readers set to English, and plans to add this functionality to other languages and platforms soon.
This follows a change made by Twitter that was designed to improve accessibility. As of March 29, 2016, people who use Twitter’s iOS and Android apps can add descriptions (also known as alternative text) to images in Tweets.
Users can enable that feature by using the compose image descriptions option in the Twitter app’s accessibility settings. The next time you add an image to a Tweet, each thumbnail in the composer will have an add description button. Tap it to see the image, and then add a description (of up to 140 characters). Doing so will help people who use screen readers to “see” your photo.
