Abstract
An input device, comprising an input interface, an adjustable capacitor, a memory and a processor, wherein the input interface is abutted with the adjustable capacitors; the memory is electrically connected with the adjustable capacitor and the processor, respectively, the input interface is used for generating pressing signals after being physically pressed so as to change the capacitance of the adjustable capacitor, the adjustable capacitor is used for correspondingly responding to the pressing signals of the input interface and outputting the capacitance changing signals, the memory is used for receiving the capacitance changing signals of the adjustable capacitor and finding corresponding output signals from the look-up table pre-stored in the memory; and the processor is used for receiving the output signals of the memory and feeding back the first input signal or the second input signal.
