Word Lens is one of the coolest iPhone apps we’ve ever seen: as you point your phone cam to a sign, the application automatically translates the words right on the video screen. Great for translating menus, traffic signs, warning messages, etc. Word Lens only works with English and Spanish for now, but more languages should be coming soon. Also, the translations are far from perfect. In most cases they are literal translations that lack proper grammar. That is an issue I am willing to cope with keeping in mind that the app works even if you are not connected to the Internet.
The video below is a demo of the app. This is augmented reality at its finest! You can learn more about the app in here.

Incredible. I spend many weeks in any new country I visit just trying to manage basic language. This could literally be a lifesaver.
Pretty Cool!
