Microsoft Edge now robotically generates picture labels for display screen readers

More than half of the pictures on the net are lacking alt textual content, in keeping with Microsoft. Image labels (different textual content) are key for a lot of who’re blind or low imaginative and prescient, as they supply display screen readers with textual content to learn aloud. Microsoft is now making an attempt to fill the hole with auto-generated alt textual content for pictures on the net.

Existing display screen readers at present learn out “unlabeled graphic” if there’s no description of a picture in any respect which isn’t very useful. Microsoft Edge has now been up to date to enhance the display screen reader expertise for all the pictures on the net with out alt textual content.

“When a screen reader finds an image without a label, that image can be automatically processed by machine learning (ML) algorithms to describe the image in words and capture any text it contains,” explains Travis Leithead, a program supervisor on Microsoft’s Edge platform crew. “The algorithms are not perfect, and the quality of the descriptions will vary, but for users of screen readers, having some description for an image is often better than no context at all.”

Microsoft Edge can now ship unlabeled pictures to its Azure pc imaginative and prescient API for processing, which is ruled by Microsoft’s privacy promises. The imaginative and prescient API creates alt textual content in English, Spanish, Japanese, Portuguese, or Chinese Simplified which may then be deciphered by display screen readers. Microsoft Edge received’t try so as to add computerized labels to photographs which can be smaller than 50 x 50 pixels, very massive picture recordsdata, pictures which can be marked as ornamental, or pictures that the Vision API categorizes as pornographic, gory, or sexually suggestive.

Microsoft is rolling out this new function instantly in Microsoft Edge for Windows, Mac, and Linux, but it surely received’t be obtainable in Edge on Android or iOS but. You can strive the brand new function out by enabling “Get image descriptions from Microsoft for screen readers” in edge://settings/accessibility, and utilizing Narrator or one other display screen reader to browse the net.

“This feature is still new, and we know that we are not done,” says Leithead. “We’ve already found some ways to make this feature even better, such as when images do have a label, but that label is not very helpful. Continuous image recognition and algorithm improvements will also refine the quality of the service.”
