How to Identify Objects, Doors, and Distances
First launched in 2019, the Lookout app for Android enables you to point your camera at an object to find out what it is. This clever app can help you to sort mail, identify groceries, count money, read food labels, and perform many other tasks. The app features various modes for specific scenarios:
Text mode is for signs or mail (short text).
Documents mode can read a whole handwritten letter to you or a full page of text.
Images mode employs Google’s latest machine-learning model to give you an audio description of an image.
Food Label mode can scan barcodes and recognize foodstuffs.
Currency mode identifies denominations for various currencies.
Explore mode will highlight objects and text around you as you move your camera.
The AI-enabled features work offline, without Wi-Fi or data connections, and the app supports several languages.
Apple has something similar built into its Magnifier app. But it relies on a combination of the camera, on-device machine learning, and lidar. Unfortunately, lidar is only available on Pro model iPhones (12 or later), iPad Pro 12.9‑inch (4th generation or later), and iPad Pro 11‑inch (2nd generation or later). If you have one, open the app, tap the gear icon, and choose Settings to add Detection Mode to your controls. There are three options:
People Detection will alert you to people nearby and can tell you how far away they are.
Door Detection can do the same thing for doors, but can also add an outline in your preferred color, provide information about the door color, material, and shape, and describe decorations, signs, or text (such as opening hours). This video shows a number of Apple’s accessibility features, including Door Detection, in action.
