Augmented Reality Cultural Application for Android

I have developed an app for museums and other cultural institutions using Unity.
I created an automatic audio guide system; the user of the application can focus on artworks using their mobile phone’s camera. The app will recognize the artworks and play the audio guide.
The application also gives the user the freedom to explore 3D objects, either with the augmented reality viewer or with the touchscreen interface.
Since it is a cultural application that can be used both for artistic works and for archaeology and history, I have taken the opportunity to practice photogrammetry and optimize the resulting models for viewing on a mobile device.
