Abstract
A joystick controller for a portable radio communication device in which a ring of elasto-resistive material which when relaxed acts as an insulator, and when stressed acts as a conductor is positioned below the joystick lever of the controller and above four pairs of contact pads arranged in a circle, and the elasto-resistive material is used to transduce the movement of the joystick lever so as to provide an electrical signal output indicative of the amount of movement of the joystick lever.
