I am pretty new to Augmented Reality so I don't understand something. i.e. I want to create an app that I will give to users at my store [hypothetical]. Whenever they are in my store the app should show info for different sections of the store [i.e. 'this is the tools section' or 'this is the gardening section'].
What is necessary to recognize indoor locations on Android and is in this case an Augmented Reality implementation the only possible solution ? Not sure if GPS coordinates are registered indoor precisely nor whether they'll be registered on that small 'distance' at all..
I would say that Bluetooth beacons is the best way to go. You can also use the strength of WiFi signals but that is vary coarse.
