  • a first sensor disposed near a space; and

    a controller coupled to the first sensor and detecting a state of the first sensor,wherein the controller performs a determination operation to determine whether an object is disposed in the space according to the detected state of the first sensor,wherein the space is an internal space of a pocket, and the first sensor comprises;

    a first conductive element disposed on a first wall of the pocket;

    a second conductive element disposed on a second wall of the pocket which is opposite to the first wall of the pocket; and

    a first magnetic element connecting with the first conductive element or the second conductive element,wherein the first conductive element is coupled to a ground terminal, and the controller is coupled to the second conductive element to detect a contact state between the first conductive element and the second conductive element.
