Abstract: A knob apparatus includes a touch panel, a touch-sensing controller, and a knob. The touch panel has multiple touch-sensing electrodes. The touch-sensing controller is coupled to the touch-sensing electrodes of the touch panel. The touch-sensing controller detects a touch event of the touch panel through the touch-sensing electrodes. The knob has a base and a knob cap. The knob cap is pivoted on the base. The base is attached to the touch panel. Multiple conductive electrodes are disposed at different positions of the base. The touch-sensing controller detects the conductive electrodes of the base of the knob through the touch-sensing electrodes of the touch panel to learn a rotation direction of the knob cap on the base.
