Abstract
A method, performed by an electronic device for triggering a function of the electronic device, wherein the electronic device comprises a button which comprises a mechanical switch actuator for triggering a function related to the button, an electromagnetic sensor for sensing touch and/or proximity of an object interacting with the button and a responsive material structure for providing haptic feedback to the object is provided. The electronic device senses touch and/or proximity of the object with the electromagnetic sensor. The electronic device generates a haptic feedback with the responsive material structure in response to sensing the touch and/or proximity of the object. The haptic feedback is associated with the function which is triggered by the mechanical switch actuator. The electronic device triggers the function in response to the mechanical switch actuator being actuated.
