The only thing you have to do to use Word Lens Translator is select the language you want to translate, point the camera at the text, and keep it as stable as possible for a few seconds. Within moments you'll see, like magic, the translation as it appears in real time on your screen.
The best uses of Word Lens Translator are for restaurant menus, posters, signs, and news headlines, since the clearer the text the smaller the chance of errors in the translation. It's important to remember, though, that the app has a very hard time deciphering handwritten script.
Word Lens Translator is an incredibly useful app for people who travel often. With it you can find out the exact meaning of any sign in any language that's not your own.
