An information processing device includes two casings that are openably/closably coupled to each other, a detection unit that is provided on at least one of the two casings and is configured to detect one of contact and proximity of an operation input with respect to an operation surface, and a control unit configured to extract a variation component, which varies along with proximity of the two casings in opening/closing of the two casings, based on a detection result, which is detected by the detection unit, and detect an opening/closing angle of the two casings based on the variation component.
