Attorney, Agent or FirmInternational ClassesG05G 9/00 (20060101)G05G 9/047 (20060101) AbstractHall effect elements are placed in proximity to magnets in such a way that the position of the magnets relative to the Hall elements is a function of the position of a joystick controller. In this way, the position of the joystick can be "read" by a machine by reference to the Hall effect voltage.Other References
