We’ve seen a lot of very useful apps appear for the iPhone, but this one takes the cake. Word Lens uses the camera on the iPhone to translate text in real-time.Watching the video included above I couldn’t believe what I was seeing, but it truly does work. Show the app some text written in Spanish, and you get an instant translation appearing on your iPhone screen in English. It also works the other way round English-to-Spanish.At the moment those are the only two languages supported, but it’s easy to see the potential for this to become the standard translation tool on mobile devices. It completely removes the language barrier when it comes to the written word.Word Lens is already available to download and use for free from the App Store.Read more at Quest Visual, via HNMatthew’s OpinionThe app in its current state only does word-for-word translations and won’t take into consideration any grammar. But in most cases you will be able to figure out what is being stated.I’m wondering how long it is going to take Google to get Quest Visual on the phone and talking about bringing this to Android. I wouldn’t be surprised if they were made an offer on the spot to come under the Google wing.Google already has efforts underway to try and create an instant speech translation tool. That would allow you to phone someone who speaks a different language, but hold a conversation with them in your own language. Word Lens is the equivalent of that but for written text.I hope they manage to improve the app to allow for grammar, but also to expand it beyond English and Spanish, turning into a truly universal translator.
