Is there any methodology / approach in testing of Augmented Reality applications?

I've been working as Quality Assurance engineer for a couple of years now and was testing mostly web-based applications. Lately I was asked to try out and test Augmented Reality App. I have discovered that information about the process of testing of augmented and virtual reality is scarse in the internet. So my question is - can someone share some useful tips or (even better) their own experience of testing ? I hope that achieved info will help in the process of building such methodology for the sake of better quality.
