1. An active human-machine interface system, comprising:

  • a user interface configured to receive input force from a user and, upon receipt thereof, to move from a null position to a control position;

    a passive force feedback mechanisms coupled to the user interface and configured to supply passive feedback force to the user interface at least when the user interface is moved from the null position;

    a position sensor coupled to the passive force feedback mechanism, the position sensor operable to sense passive force feedback mechanism position and supply a position signal representative thereof, anda circuit coupled to receive at least the passive force feedback mechanism position signal and operable, in response thereto, to calculate the input force using the position signal.
