I wanted to do AR based on a page of text. So it would hover images over certain words. Any idea if that's possible? Any idea where to start learning about it?

You're looking for pattern based AR (unless the words on your paper have precise GPS coordinates)

I haven't look at it much yet, but you might have some luck with the new Quallcom AR SDK.

Thanks. A lot of times knowing what to search for is half the battle. I'll see what pattern based AR turns up.
