Abstract
A peripheral device comprises a control unit and an operating body. The operating body electrically coupled to the control unit comprises a keyboard layout layer, a capacitance sensing layer and a resistance sensing layer. The keyboard layout layer shows a keyboard layout to be operated. The capacitance sensing layer disposed beneath the keyboard layout layer is capable to detect a finger contact and generate a contact path according to the finger contact. The resistance sensing layer, which is disposed under the keyboard layout layer, stacked with the capacitance sensing layer, is capable to detect a pressing operation on the keyboard layout layer and generates a press signal according to the pressing operation.
