ABSTRACT:
A joystick controller is characterized by a control shaft that has toward its lower end a hemispherical-shaped member having a spherical surface. The control shaft extends upwardly through an opening in a top wall of a housing, and a circumference of the opening defines a beating for the spherical surface of the control shaft hemispherical member while a bottom of the control shaft is pivotally supported on a fulcrum within the housing. An upper end of the control shaft is manually movable to pivot the control shaft, with the spherical surface then moving in the bearing. The control shaft is coupled to x-y movement indicators comprising linearly movable variable impedance devices, which generate signals in accordance with the amount and direction of pivotal movement of the control shaft.
