"CityViewAR is a mobile Augmented Reality application that allows people to see how the city was before the earthquakes and building demolitions. Using an Android mobile phone people can walk around the city and see life–sized virtual models of what the buildings looked like on site before they were demolished, and see pictures and written information. Hundreds of 3D models of key city buildings have been made available from architect Jason Mill of ZNO, while the Christchurch City Council and Historic Places Trust have provided photographs and building histories.
CityViewAR is based on the HIT Lab NZ Android AR platform which uses the GPS and compass sensors of mobile phones to enable virtual information to be overlaid on live video of the real world. Android AR makes it easy for Android developers to build their own outdoor AR applications. The software was previously used for showing individual buildings, but this is the first time that it has been used to show dozens of buildings at once, and the first time in world that mobile phone AR has been used for earthquake reconstruction."

"Twitter 360 is a new application specifically developed for the iPhone 3GS that enables you to visualize your Twitter friends located in your nearby environment, thanks to a unique Augmented Reality functionality using the iPhone camera.
Twitter 360 is one of the first iPhone applications to use the new Twitter's Geotagging feature to geotag your tweets. Please, note that Twitter 360 does not intend to be a fully Twitter client, our goal is to provide a different approach to the Twitter experience. We are already working on new ideas to be added in this application."
"The New Scientist writes on the UK service TagandScan 'By tagging messages to mobile phone 'cells', users can post reviews, leave notes for friends, or even organise demonstrations'. When a user logs onto the TagandScan site using their cellphone, they can opt to be automatically located according to network cell from which they are calling. They can then create a message or view ones already left in that cell by other users.
TagandScan was created by New York company Cimarrones and has been undergoing UK field trails for the past month. Cimarrones' president Ryan Janssen says he has been surprised by the ways people have used the service in testing. 'We had some preconceived notions but people are using them in ways we never intended,' Janssen told New Scientist.
Janssen believes people may also use TagandScan to organise political gatherings or create their own guides to a city's bars and restaurants."
