Abstract
An input device (302,316) includes a plurality of magnetic sensors (104,108,112) for measuring the components (106,110,114) of a magnetic field (102) at the position of the input device (302). The magnetic field may be the geomagnetic field of the earth or a magnetic field generated by a local magnet (602). The data of at least two (104,108) of the sensors are used for calculating a first signal (208) for controlling the translation movement of a graphical element (204) on a display (202).
