Abstract: An input apparatus includes a capacitive touch element, at least a pressure-based sensing element, and a control circuit. The control circuit includes a switch unit and a shared processing unit. The switch unit is coupled to the capacitive touch element and the pressure-based sensing element, for selectively generating an output signal according to a touch signal generated by the capacitive touch element or a sensor signal generated by the pressure-based sensing element. The shared processing unit is coupled to the switch unit, for processing the output signal to detect a touch event. A touch event processing method includes scanning traces for detecting if a touch event occurs, checking whether the touch event occurs in a capacitive touch element or a pressure-based sensing element, and processing the touch event with a corresponding algorithm.
