Last year, Google bought re-CAPTCHA that it was used to create and translate Captcha codes; so now we have the Google Goggles product, their latest.
Goggles is made only for latest Android phones that use OCR technology to recognize text from images and to translate it.

For example, if you are in a foreign country and you don’t understand something from the Menu, only make a picture to it and use Goggles to translate the text. Nice and easy.
