An attitude- and motion-sensing system for an electronic device, such as a cellular telephone, a game device and the like, is disclosed. The system (20), which can be integrated into the portable electronic device, inclu a two- or three-axis accelerometer (24) and a three-axis magnetic compass (22). Data about the attitude of t electronic device from the accelerometer and magnetic compass are first processed by a signal processing u (25) that calculates attitude angles (pitch, roll, and yaw) and rotational angular velocities. These data are then translated by a translator (29) into input signals (27) for a specific application program associated with the electronic device (Fig. 2).
