Title: JOYSTICK CONTROLLER
Abstract:
A joystick controller (10) for a portable radio communication device in which a ring of elasto-resistive material (30) -which when relaxed acts as an insulator, and when stressed acts as a conductor- is positioned below the joystick lever (12) of the controller and above four pairs of contact pads (34) 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.
