Snapchat can be thought of as the most popular Augmented Reality app. They are the only app I see widespread in North America that convinced users to actually use QR codes, if only occasionally. Filters are an example of great UI in AR: it's intuitive because it interacts with your natural world. Snapchat is very well positioned to take location-based features beyond just filters. I think these kinds of real-world interactions are an awesome trend and a lot of the tech has yet to be built. (It also looks like the author removed the popovers. I didn't see any popups when reading the article.)
