1st augmented reality app
Beating out acrossair's Nearest Tube, French company Presselite has released the first augmented reality app for the iPhone, Metro Paris Subway 3.0. Previous versions have relied on 2D maps as users navigate the Paris subway system, identifying routes and points of interest. Version 3.0 allows users to find POIs using a live video mode, on top of which the app overlays icons and distance markers.
As a user walks through Paris, icons shift relative to a phone's position, judged according to compass and GPS data. Because of the function's dependence on compass headings, augmented reality can only be used with an iPhone 3GS. The app costs $1; other changes in v3.0 include Google Maps integration, push notifications for route disruptions, and in-app purchase options for bus routes and different POI categories.
