Microsoft's computer vision app for the blind and poor-sighted, Seeing AI, just became more useful for those moments when you're less interested in navigating the world than learning about what's on your phone. The company has updated the iOS app with an option to explore photos by touching them. Tap your finger on an image and you'll hear a description of both the objects in that scene as well as their spatial relationship. You can get descriptions for photos taken through Seeing AI's Scene channel, but they'll also be available for pictures in your camera roll as well as other apps (through options menus).
