Abstract: This application relates to a magnetic field sensing-based noncontact button apparatus, an elevator control panel, and an operating method thereof. In one aspect, the operating method includes collecting a magnetic field sensor value corresponding to each of a plurality of buttons based on an action of a user for button manipulation. The method also includes assigning a weight value, used for activating a button, to a Z-axis value of the magnetic field sensor value corresponding to a button input direction of the user for each button and collecting number of uses of each button. The method further includes adjusting a variation width of a weight function based on the Z-axis value based on the number of uses of each button to construct a surface data set corresponding to each button, and setting the surface data set to learning data to learn an algorithm for activating the button.
