1. A human machine interface comprising:

  • a capacitive touch screen including a capacitive sensor, the capacitive touch screen being configured to display text characters and/or graphical information; and

    a control device rotatably coupled to a structure such that the control device is superimposed over the screen, the control device including at least one electrically conductive element, the control device being configured to rotate about an axis substantially perpendicular to the screen such that the at least one electrically conductive element follows the rotation of the control device;

    wherein the capacitive sensor is configured to sense a rotational position of the at least one electrically conductive element; and

    wherein the control device is actuatable in directions toward and away from the screen such that the at least one electrically conductive element follows the movement toward and away from the screen, the capacitive sensor being configured to sense a position of the at least one electrically conductive element in the directions toward and away from the screen without the control device touching the screen.
