A method ( 500 ) and apparatus ( 601 ) generate an input signal based on the orientation of a device. A sensor ( 302 ) such as a camera, a gyro, or an accelerometer detects a change in device orientation and generates a position input signal that is provided to an application program ( 612 ) such as a game program, a text messaging program, or a user interface program to affect an operation thereof. The input signal can, for example, affects a navigation position associated with the application program.
