A controller(20) for converting a force applied by a user in at least one direction into an output indicative of the force applied, comprising: a support (30) comprising a first part(32) of a capacitor assembly (40A-D)(40A'-D'); and a user-engageable part (50) resiliently coupled to the support (30) and comprising a second part (42A-D)(42A'-D')of the capacitor assembly (40A-D)(40A'-D'), wherein movement of the user-engageable part (50) relative to the support (30) varies the capacitance of the capacitor assembly(40A-D)(40A'-D'); characterised in that the user-engageable part (50) is substantially immovable relative to the support (30) in the at least one direction. |
