Word Lens translates text from the iPhones camera in real time. Simply point the camera at any text, such as a street sign and the app will instantly translate the words for you on the fly. Word Lens doesn’t have to have an internet connection to perform this magic, however, instead it handles all of the processing on the iPhone itself.
Technology really is amazing.
within a year, we will probably have an app for voice communication that does translations on the fly...(speak " your native language" and translate to "any language" in a HAL 9000 voice.
