The document discusses the iPhone's motion sensors including the accelerometer and gyroscope. It describes how they are used to sense device orientation, stabilize camera images, and provide precise 6-axis motion sensing input for activities like gaming and navigation. The sensors together allow the device to track its movement in 3D space.

4. * The combined data from the accelerometer
and the gyroscope provides detailed and
precise information about the device's 6-axis
movement in space.
* The 3 axes of the gyroscope combined with the
3 axes of the accelerometer enable the device
to recognize approximately how far, fast, and
in which direction it has moved in space.
