Augmented reality iOS app in small places - possible?

Is it possible to build an augmented reality iOS app designed to work in small spaces, like a school? I 开发者_如何学编程have seen many apps with AR but in big places, like cities. I want to do this in a school - is that possible?

Following is the link for ARTool Kit. This helps you a lot...

You can do AR anywhere. Location based AR can get tricky indoors though. AR uses several tools to determine where you are standing and where you are looking. These include GPS, Compass, Accelerometer, and Gyroscope. What you may struggle with is getting a GPS reading with the accuracy needed for a small space, especially inside a building. I would expect that you will not be able to rely on GPS at all for your application. So you will need to find some other way to determine location. You could do some sort of system that relies on stationary QR codes or known points.

It's definitely possible. You can create an augmented reality app anywhere. Why wouldn't it work in a school?
