"Social Augmented Reality Mobile Location-based Service: “Sekai Camera” (World Camera)."

Google could and probably will develop a website (a-la AdWords) where every business in the planet will be able to geo-tag their shop, service etc… for free. But the trick is that you could tag not only your business name, but also place ads. And of course Google will charge for this service… In Enkin’s video demonstration, we see an example with a hospital and a subway station geo-tagged and visible live through augmented reality. Now replace this with a restaurant or a shop. This shop pays Google to advertise so below their business name, the tag would also display for example a promotion for an article. Just imagine the potential! This concept has the potential of becoming something similar to what adwords is to Google: a drastic profit machine! On top of that, Google could license the service to TomTom or other GPS manufacturers, so in your car you will actually see in real-time the directions and tags through a live video, instead of the boring 3D-graphics we all know.
