The present invention concerns a clickable knob which can be placed on a touch sensor for providing a physical clickable knob on the touch sensor. The detection of the user input of the clickable knob, i.e. the click state and the rotation state, is detected based on a detection of corresponding click and rotation detection points of the clickable knob by touch pixels of the touch sensor.
