What do you get when you mixt he social features of FourSquare with Augmented Reality systems?  TagWhat, a new mobile augmented-reality location-based service that’s free for all and allows users to tag places in geophysical space and share them with their friends.  Each market can contain any number of scraps of information such as emails, SMS, photo’s, URL’s, and even cross-posting to other networks like Facebook & Twitter.  Just like FourSquare, you can ‘check-in’ at a location and then share your photos and comments with anyone else, but combine it with turn-by-turn directions for your friends and more.

In particular, TagWhat h as already approached businesses and created “Channels” for food, drink, Wikipedia, and a direct link to FourSquare.  Advertising & Real-Estate potential is huge, as well, allowing advertisers to target physical locations for AR ads.

“Tagwhat gives us a tool to connect stories and places ” said Anne Dodge Program Director National Public Housing Museum. “It lets us reach the broadest possible audience in the most intimate way expanding our reach and embedding our stories in the places where they actually happened. This is the technology we ve been waiting for.” “
