1. A method of providing haptic feedback by a haptic device in an electronic device, the method comprising:

  • Identifying a user input to a specific application of the electronic device, the specific application associated with at least one graphic displayed on a display of the electronic device, and the user input associated with a location of a movable output icon;

    accessing, from a memory, a feedback profile of the specific application;

    detecting, by an input sensor;

    a magnitude of a force exerted on a feedback surface of the haptic device; and

    a change in the magnitude of the force exerted on the feedback surface;

    determining, by a processor, that the magnitude of force exerted on the feedback surface, as a result of the change, has crossed a threshold defined by the feedback profile;

    generating, by the processor, an electrical signal corresponding to a haptic feedback operation defined by the feedback profile; and

    providing the electrical signal to an electromagnetic actuator coupled to the feedback surface;

    whereinthe electromagnetic actuator causes the feedback surface to displace a set distance in response to the electrical signal.
