Word Lens is an app that makes use of augmented reality in a really practical way. You point your camera at what you want to translate, such as words
printed on street signs, walls, posters, magazines, and they get instantly translated on screen.
There’s a demo version to try, while the paid version lets you choose from one of three languages (Spanish, French, Italian). You can also look-up
translations by typing them in or taping on a word, which some times can be more reliable than translation results from the camera.
