Compass technology

Seen on the apple iPhone.

A built-in digital compass that works just like a magnetic needle compass can let you know which way you’re facing, digital compass rotates maps to always match the direction you’re facing. You can also use the compass on its own.

A magnetometer that works as a digital compass will enable the iPhone to determine which direction it is being held in. This will allow useful things like turn-by-turn navigation (time to ditch that satnav?) and ‘augmented reality’ apps that superimpose info about a location onto a camera view or Google Street View image.

Newest iPhone App

Newest iPhone app is a camera installment that lets you move the camera around via cumpus technology and shows londons underground to the user depending where the camera is pointed. This means the user can see more than the naked eye and can position themselves to be where they need to be more easily.
