Twitter has announced a new feature which will help make their platform more accessible for visually impaired users. The feature will now let users add alternative text (alt text) to images in tweets, which is a description for the image.
Twitter says the new feature will be available for its iOS and Android app users.
In a blogpost announcing the new feature, Twitter points out that the same can be activated by going to the app’s accessibility settings. Users will have to enable the compose image descriptions option in the settings.
The blogpost reads, “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. People who are visually impaired will have access to the description via their assistive technology (e.g., screen readers and braille displays). Descriptions can be up to 420 characters.”
Twitter says that in order to that ensure publishers and third-party clients also have the capability to add alt text to images, they have extended the same to the REST API and Twitter Cards.
