An augmented reality experiment in react native

Image of googleplay

Try beta release:


A simple and small app that translates in real time what you see from your mobile.

Augmented reality is an overlay of content on the real world, it means to add enhancements to the existing reality in order to make it more meaningful.

With the help of advanced Google Cloud technology such as Cloud Vision, the information and the environment surrounding can become interactive.

It is inspired from Google's "Giorgio Cam" AI and react-native-camera-translator experiments.

For a thorough discussion, please read the following blog post about it.

Selecting a language.

I created the language selector using snack expo using Animated and PanResponder from react native.

Rotating the dialog

I am also using the mobile accelerometer to create an animated transition in order to improve the user experience when rotating the mobile.
