Abstract
Printed matter including a viewed-page detection electrode provided to a primary surface of a first printed medium among a plurality of bound printed media, the viewed-page detection electrode being so disposed that, when the printed matter is closed, at least part of the electrode provided to a first page overlaps with an electrode provided to a second page facing the first page; a selected-area detection electrode provided to the primary surface and located at a position different from the viewed-page detection electrode; a first determination unit connected to the viewed-page detection electrode to determine a page that is currently open based on capacitance generated in the viewed-page detection electrode; and a second determination unit connected to the selected-area detection electrode to determine whether the selected-area detection electrode of the open page has been touched by a user based on capacitance generated in the selected-area detection electrode.
