Patent ID: 8829894

Claim:
A control device configured to provide user control signals comprising: a magnetic flux sensing unit configured to provide two-dimensional angular orientation information with respect to a magnetic field acting on said magnetic flux sensing unit, said user control signals being dependent on said two-dimensional angular orientation information; a socket; a shaft terminating in a ball, said ball arranged to be rotated around two axes of rotation in the socket; said ball comprising a cut-out region, said magnetic flux sensing unit being mounted onto said socket and protruding into said ball via said cut-out region; and a magnet arrangement comprising at least two permanent magnets configured to generate said magnetic field, wherein said magnet arrangement and said magnetic flux sensing unit are arranged to be reoriented relative to one another within a predetermined range of movement, and said at least two permanent magnets are arranged relative to said magnetic flux sensing unit such that said magnetic field experienced by said magnetic flux sensing unit is substantially uniform throughout said predetermined range of movement.
