Using AI to give people who are blind the "full picture"

Everything that makes up the web--text, images, video and audio--can be easily discovered. Many people who are blind or have low vision rely on screen readers to make the content of web pages accessible through spoken feedback or braille. For images and graphics, screen readers rely on descriptions created by developers and web authors, which are usually referred to as "alt text" or "alt attributes" in the code. However, there are millions of online images without any description, leading screen readers to say "image," "unlabeled graphic," or a lengthy, unhelpful reading of the image's file name. When a page contains images without descriptions, people who are blind may not get all of the information conveyed, or even worse, it may make the site totally unusable for them.
