Nearest Tube

Apparently if you have an iPhone 3GS and you're looking for the nearest burger in Paris you're in luck. Presselite has released their 99 cent iPhone application, Metro Paris Subway.

It allows iPhone users to view many points of interest, including metro and bus stations, superimposed over live video of current surroundings. Just a month ago we explored a video of the prototype NYC version of a similar augmented reality application.

Finally, the iPhone 3GS digital compass is getting a workout. Software developer acrossair has submitted the first augmented reality application to the Apple AppStore for approval. The app is called Nearest Tube, and will help Londoners plan routes and find the closest underground station. What's unique about this process is how the app delivers information.

Instead of a static map, Nearest Tube displays subway information in real-time, overlaid in 3D on top of live video of the user's surroundings. Holding the iPhone 3GS horizontal will show arrows pointing to different train stops, and tilting the device upwards will overlay signs in the direction of different stops. These signs look like a heads-up-display, and give more information about how far away the station is and what lines connect there.
