Button with mechanical switch, electromagnetic sensor and haptic feedback, and method

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 the 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, the method comprising:

• sensing touch and/or proximity of the object with the electromagnetic sensor;
• generating a haptic feedback with the responsive material structure in response to sensing the touch and/or proximity of the object, wherein the haptic feedback is associated with the function which is triggered by the mechanical switch actuator;
• and
• triggering the function in response to the mechanical switch actuator being actuated.

A non-transitory computer readable medium comprising a computer program, comprising computer readable code that, when executed on an electronic device, causes the electronic device to perform a method for triggering a function of the electronic device, wherein the electronic device comprises a button that comprises a mechanical switch actuator for triggering the 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, wherein the method comprises:

• sensing touch and/or proximity of the object with the electromagnetic sensor;
• generating a haptic feedback with the responsive material structure in response to sensing the touch and/or proximity of the object, wherein the haptic feedback is associated with the function which is triggered by the mechanical switch actuator;
• and
• triggering the function in response to the mechanical switch actuator being actuated.
