Google Translate just got Word Lens, basically. The new feature in the latest update of the Google Translate app lets you take a picture in-app, and highlight text you want translated from one language into another. It's pretty cool.
The translation is different from Word Lens in that it's not live AR translation. You take a picture and then rub your finger over the words you need translated, and the app does its best to accomodate. Word Lens was never accurate enough to, say, use it to read a book or foreign movie credits, but the live-action translation means you don't have to reset to get it right. This new Google Translate function makes you go all the way back to the beginning if you miss a crucial part of the translation. Here's Word Lens translating the same image shown on Google Translate above:
