Word Lens is an amazing new iPhone app that instantly translates language right before your eyes. Using the video camera on your iPhone, Word Lens can scan, for instance, the words on a sign or menu. The app then runs that text through optical character recognition software and displays the translated type in context. Because Word Lens looks up words in its onboard dictionary, you don’t need to be connected to the internet for the app to work; there is no delay, roaming fees, nor reception problems to contend with. It’s a $4.99 paid app, which for the moment offers only English to Spanish and Spanish to English translation.
Techcrunch reports that the app is the culmination of 2 1/2 years of work from founders Otavio Good and John DeWeese. Good says in the video below that he got the idea for the app when he was in a foreign country and couldn’t read the language on a sign. He thought to himself “why doesn’t my cellphone do this?” Now that the translator is complete and deployed to the App Store, Good notes that Word Lens is not perfect, but it usually gets the point across. It doesn’t work on handwritten type, very stylized fonts, or cursive. . Sometimes the translation will have mistakes, and may be hard to understand. If a translation fails, there is a way to manually look up words by typing them in.
