1. An apparatus comprising:

  • a structure comprising a conductor and an insulator;

    a sensor configured to sense position information when a body member touches the insulator in a touch sensitive area,the sensor being configured to detect the position information before the body member touches the insulator in the touch-sensitive area; and

    a controller configured to;

    process the position information and determine parameters of an electrical signal provided to the conductor;

    control a force between the structure and the body member by varying the electrical signal to the conductor based on the parameters; and

    apply the electrical signal to the conductor at a first intensity before the body member touches the insulator and apply the electrical signal to the conductor at a second intensity after the body member touches the insulator.
