Twitter’s latest update is designed to help those users who are visually impaired by allowing users to attach image descriptions within their Tweets, the update rolls out to Twitter’s iOS and Android apps users.
In a blog post announcing the update, Twitter’s staff engineer Todd Kloots said “As a core part of the Twitter experience, it’s important that images shared on our platform are accessible to everyone, including those who are visually impaired.
“With this update, we’re empowering everyone to ensure content shared on Twitter is accessible to the widest possible audience.”
People who are visually impaired will have access to the description via their assistive technology such as text-to-speech screen readers and braille displays.
How to use the feature:
- Enable this 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 add a description to the image. Descriptions can be up to 420 characters.
