Professor Meguro – Augmenting Reality in Japan

http://blogs.dickinson.edu/japan2010
Augmented reality is a way of displaying real time digital information on top of the real world as seen through the camera of your mobile phone.  Professors Bates and Meguro used the alternate reality program Layar during the Japan Summer Program to have students choose a location in the city and then add information and media.  Their contributions are now visible to any visitor via their mobile device.

How does it work? 
The idea is simple: Layar works by using a combination of the mobile phone’s camera, compass and GPS data to identify the user’s location and field of view, retrieve data based on those geographical coordinates, and overlay that data over the camera view.
