One of the coolest features of the iPhone and iPod Touch is the built-in accelerometer, the tiny device that lets the iPhone know how it’s being held and if it’s being moved. The iPhone OS uses the accelerometer to handle autorotation, and many games use it as a control mechanism. It can also be used to detect shakes and other sudden movement.
