Abstract
A user-interface for controlling a data processing system using a joystick includes a joystick for controlling input to the data processing system. The joystick has a pivoting component for assuming tilted positions by tilting in directions that lie in a reference plane associated with the component, and a sensor for sensing at succeeding sampling moments the direction corresponding to succeeding tilted positions of the component, and a difference determination device for determining a difference in direction between a first direction sensed at a first sampling moment and a second direction sensed at a second sampling moment after the first moment, and a parameter modifier for modifying a value of a parameter of the data processing system by adding or subtracting a difference value that depends upon the difference in direction.
