An electronic device ( 100, 200 ) contains a first joystick mechanism ( 114 ) and a second joystick mechanism ( 112 ), each joystick mechanism ( 112, 114 ) extending outside of substantially opposed outer surfaces ( 403, 414 ) of the electronic device's casing. When a directional mechanical force is applied to one joystick mechanism ( 112, 114 ), at least one of a plurality of switches ( 410 ) may be engaged. The joystick mechanisms ( 112, 114 ) are electrically coupled, and each mechanism will provide the same functionality. The joystick mechanisms ( 112, 114 ) may be further mechanically coupled, whereby applying a directional mechanical force on one joystick mechanism will move the other joystick mechanism in the opposite direction. Additionally, the joystick mechanisms ( 112, 114 or 1002, 1004 ) may contain a sensor ( 416 ) capacitvely coupled to a conductive end cap ( 404, 405 ) to detect from which side of the electronic device ( 100, 200 ) a joystick mechanism is being moved.
