1. An electric device comprising:
- a force and touch sensitive screen configured to detect and output a detection signal representing a force generated by an object interacting with the force and touch sensitive screen;
a haptic feedback element configured to generate a haptic feedback;
a controller configured to control the haptic feedback element based on the force generated by the object interacting with the force and touch sensitive screen;
a first filter element arranged between the force and touch sensitive screen and the controller, wherein the first filter element is configured to filter out the force generated by the object interacting with the force and touch sensitive screen from a force generated by the haptic feedback.

Abstract
The invention relates to a method and an electric device comprising a screen (110), cooperating with said screen a sensor for detecting a presence of an object on or close to said screen, a controller (120) and a feedback element (140). The controller (120) is configured to interpret said presence of the object and calculate a force value and control said feedback element (140) to provide a feedback with respect to the force value.

15. An electric device comprising:
-
a force and touch sensitive screen configured to detect and output a detection signal representing a force generated by an object interacting with the force and touch sensitive screen; a haptic feedback element configured to generate a haptic feedback; a controller configured to control the haptic feedback element based on the force generated by the object interacting with the force and touch sensitive screen, wherein the amplitude of the haptic feedback is dependent on the force generated by the object interacting with the force and touch sensitive scree, wherein the amplitude of the haptic feedback is proportional to the force generated by the object interacting with the force and touch sensitive screen; wherein the detection signal is directly proportional to a magnitude of the force generated by the object interacting with the force and touch sensitive screen. - View Dependent Claims (16)
