ABSTRACT:
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, 114or1002, 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.
