A case for an electronic device including a coupling member detachably coupled to at least a part of the electronic device. A cover, which has one or more folded positions ranging between an opened state and a closed state, the cover extends from the coupling member in a to cover a display of the electronic device, and at least one Force Sensing Resistor (FSR) sensor disposed in the cover to generate an interrupt based on a pressure applied thereto. The at least one FSR sensor includes one or more inner FSR sensors disposed on an inner surface of the cover, and one or more outer FSR sensors disposed on an outer surface of the cover.
