Microsoft has come up with its own app known as Seeing AI which allows blind and limited-vision folks to convert visual data into audio feedback. With this new feature, users can touch to explore the objects and people in photos.
You just need to take a photo or open one up in the viewer and tap anywhere on it. Users will be able to tap their finger to an image on a touch-screen in order to hear a description of objects within an image.
This app is free and can be downloaded for iOS devices.
