Augmented reality app
acrossair, a developer based in London, England, says it is waiting for approval on what should be the first augmented reality application for the iPhone. Called Nearest Tube, the app points users in the direction of the closest London Underground subway station. Distinguishing it from titles like Google Maps is the use of a live video mode, on top of which the app overlays graphics indicating which direction to travel.
In this main view, stations are identified by name and distance, as well as which subway lines connect. Holding an iPhone flat switches to a view of all 13 Tube lines, while tilting a phone upwards shows more distant stations in the form of stacked icons. Because the app relies on both compass and video fuctions, it is only compatible with the iPhone 3GS. Planned pricing is so far unknown.
