Abstract

See full text

A joystick mechanism includes a housing, a substantially spherical magnetic ball rotatably mounted on the housing, a joystick shaft attached to the magnetic ball, and a pair of magnetic effect sensors operatively positioned adjacent the magnetic ball. The sensors, which are positioned along the x and y axes, are aimed perpendicular to each other and the z axis. Thereby, movement of the joystick and the ball causes a change in the magnetic field which is measured and indicated by the sensors.
