Hello,

So I am making an educational app, and I wanted to add AR to it, so to start I have this physical map it's a matrix of 16 cases (4 x 4) each case has a unique code, I want to have the app recognize each code and display a picture of choice there, that's where the AR comes to play, I have tried using Vuforia + Unity but the result wasn't as good as I wanted, also I prefer if it's something I can implement to Android Studio easily, please share your ideas on this I just want guidance on how to start, like what to search for in order to start doing this, any development kits or frameworks I can use.

Edit 1: if you need any more details or something please ask me!

Edit 2: I heard that Google AR Core is good but I really didn't find anything useful on how to implement my idea
