The knob can still be seen in some specific places, such as the ECG monitor in the hospital, or the mixing console in the school radio room. These professional instruments still have controllers of various sizes. There are also consumer electronics products that recognize the intuitive, easy-to-use nature of the knob, so it is also used as an auxiliary interaction solution. If the controllers that are digitized and graphically pursued are unified and efficient, then the knobs and so on are retained, perhaps the original unconscious awareness of this mode of operation.
