Augmented reality on a mobile phone isn’t new, but KDDI has a very nice setup using a phones internal GPS + camera and Twitter. I’m sure you’re aware of what augmented reality is like on a phone… Just in case, let’s say that thanks to your phone scamera you can see additional information on top of real settings… Imagine you’re watching a street via your mobile phone’s camera, some virtual information or ads pop-up on specific details.

Now with the usage of a GPS and Twitter, KDDI allows you to see virtual Twitts on top of real sceneries. Imagine that you’re walking down a street and people who walked the same street a couple of day priorl Twitted some points of Interest (photo, text and GPS location) you can immediately see them… Ideally, and if many people do this, you could walk on any street in the world and get additional information or must see POIs from other Twitter users…

Finally a useful usage for Twitter!
