Some months ago Zagat released the first US "augmented reality" app for Android phones: Zagat/nru. There's no iPhone version to date. I totally missed it however. But after I wrote this post, "Augmented Reality Is Also a Form of Search," Zagat contacted me and reminded me about the app:
Based on your current location, nru shows the closest Zagat-rated establishments, visually plotted on a radar screen showing compass directions and distance from origin
It doesn't use the camera but shows you nearby restaurants around a compass-like interface, pictured below. You can also see how it works in the following demo video:
Functionally it's similar to the "near me" apps that have a less splashy interface, but equally match user location to the data. The Zagat app starts to give one a concrete sense of the possibilities -- and limits -- of augmented reality technology and its use cases.
Augmented reality apps will increase but will be just one "search" method among several used by smartphone owners.
