Last week a friend showed me an augmented reality app, which instantly translates texts captured by a smartphone cam through augmenting the captured camera image. I never thought that such application are already that good! The app immediately translated a given text into german and created an overlay on the camera image to override the original text. This kind of apps can be really useful when visiting a country in asia.
Unnecessary to mention that i did not had that application when i visited South Korea 😉
