A joystick apparatus has a housing and a printed circuit board in the housing. A shaft is pivotably connected to a U-joint assembly to allow movement of the shaft relative to the center position within a circle. A concentric reduced power zone circle is associated with the circle. Operation of the joystick within the reduced power zone circle uses less power than operation outside of the reduced power zone. A knob and a magnet are located on the shaft. A Hall effect integrated circuit detects movement of the magnet in response to corresponding movement of the shaft by a user and generates a corresponding proportional joystick output signal indicative of a direction and an extent of rotation of the shaft. A multifunction joystick control system has a joystick configured to provide multiple operational modalities on a joystick. An electrical interface connects the joystick apparatus and the host central processing unit.
