Word lens is not really Linux, or hardware related. But i’m sure every tech geek will love this.
What is World lens
Word lens is an app that can translate text from signs, papers or similar through the phones camera. I think it would be simpler to just show you their official video:
The app is not perfect, and if you try to translate something on a computer screen, it will “flicker” a bit. But it’s a nice and useful tools to have in your pocket when you are travelling or just visit another country, specially because it will work without any internet connection!
