Augmented Reality, Museums, and Accessibility

I’ve been playing with smart-phone enabled augmented reality and museum collections in some of my classes. I’d be interested in talking with folks about this work, showing how we use various free software tools to do it and the outcomes (my class’s augmented reality pop up museum catalogue). I’m wondering how this tech could be used more generally as part of exhibition design, and in particular, in conjunction with accessibility considerations. Maybe we could try brainstorming some options, thinking through what an ideal use-case might look like?
