We’re taking it to the next level and letting you instantly translate text using your camera—so it’s way easier to navigate street signs in the Italian countryside or decide what to order off a Barcelona menu. While using the Translate app, just point your camera at a sign or text and you’ll see the translated text overlaid on your screen—even if you don’t have an Internet or data connection.

This looks really cool. I remember traveling in Italy and not being able to understand the signs at the train station. This would have come in very handy.
