The software for the new iPhone 3Gs uses an inbuilt video camera and GPs sensors to display the exact location of nearby stations. It even reveals which Underground lines are running beneath your feet. The software is expected to go on sale next week for 1.19, although it is still awaiting approval from Apple. By moving the phone you can estab- lish the nearest Tube station. If you tilt the phone upwards you will see stations further away, and images move in real time as you walk. The software is believed to be the first commercially available on a mobile phone to use augmented real- ity, a system which superimposes information on to live pictures. Developers say it could lead to the ultimate travel guide, where pointing a camera at a landmark shows infor- mation about it. Phone firms such as Nokia have already tested such systems, although they are not yet widely available. Chetan Damani, of London firm acrossair, which developed the software, said: What we wanted to create was something which was based on real life. By using the sensors inside the iPhone we were able to superimpose Tube map loca- tions on to the display. Mr Damani said the firm hoped to add a feature which would show users live Tube data from Transport for Londons countdown boards. It is also consider- ing adding bus routes, along with versions for other cities. ThE Nearest Tube software uses three processes to pinpoint where the user is. Using GPs, it takes a feed from satellites to find the phones location. Then a compass in the phone checks which direction the user is facing and an accelerometer checks whether the phone is facing up or down. it then uses a database of Tube stations and overlays the details on to a live video display from the devices camera.
