Twitter has updated its iOS and Android apps to makes its service more convenient for mobile users with visual impairments.
“With this update, we’re empowering everyone to ensure content shared on Twitter is accessible to the widest possible audience,” Twitter staff engineer Todd Kloots wrote in a blog post.
“We’re excited to empower our customers and publishers to make images on Twitter accessible to the widest possible audience, so everyone can be included in the conversation and experience the biggest moments together.”
To make use of the new feature, simply use the compose image descriptions option in the Twitter app’s accessibility settings. Then, the next time you add an image to a tweet, you will have the option of typing in up to 420 characters in text by tapping the add description button.
“People who are visually impaired will have access to the description via their assistive technology (e.g., screen readers and braille displays),” Kloots added.
Twitter has extended its platform products to both the REST API and Twitter Cards to ensure publishers and third-party clients also have the capability to add alt text to images.
