Abstract: The invention relates to a motion-input device for a computing device, comprising a housing; a three-axis acceleration sensor arranged in said housing for outputting inertia signals related to the orientation and the movement of the motion-input device with a three-axis compass arranged in said housing, for outputting magnetic field signals related to the magnetic field orientation of the motion-input device, wherein said motion-input device is provided with a transfer component for transferring said magnetic field signals and said inertia signals to said computing device.

Abstract: A system, apparatus and method for incorporating sensor functionality into mobile communication devices having a host process and employing at least one memory, such as a removable memory card. Access to the removable memory card by the host process is facilitated using a digital interface, and storing sensor data from one or more sensor modules into a local memory. The host process of the mobile communication device is coupled to the local memory via the digital interface which is used by the host process to access the removable memory card. The sensor data may then be accessed from the local memory by the host process via the digital interface.
