Abstract
A control device is provided configured to provide user control signals. The control device comprises a magnetic flux sensing unit configured to provide two-dimensional angular orientation information with respect to a magnetic field acting on the magnetic flux sensing unit, and the user control signals are dependent on the two-dimensional angular orientation information. The control device further comprises a magnet arrangement comprising at least two permanent magnets configured to generate the magnetic field. The magnet arrangement and the magnetic flux sensing unit are arranged to be reoriented relative to one another within a predetermined range of movement, and the at least two permanent magnets are arranged relative to the magnetic flux sensing unit such that the magnetic field experienced by the magnetic flux sensing unit is substantially uniform throughout the predetermined range of movement.
