An operation control device comprising: a contact detection unit for detecting contact of an operation body with a display surface of a display unit on which information is displayed; a pressure detection unit, provided on the display unit, for detecting a pressure at which the operation body presses the display surface of the display unit; and an operation control unit for changing a display state of the information displayed on the display unit in a forward or reverse direction on the basis of an amount of pressure detected by the pressure detection unit until the operation body makes contact with and is separated from the display surface of the display unit, and wherein, when an object list in which a plurality of objects are arranged in one direction is displayed on the display unit, the operation control unit: scrolls the object list in the forward direction step by step every time the pressure detected by the pressure detection unit exceeds one or more pressure thresholds set step by step, and scrolls the object list in the reverse direction, which is a direction opposite to the forward direction, step by step every time the pressure detected by the pressure detection unit falls below the pressure thresholds set step by step, wherein the operation control unit ends a change in the forward or reverse direction of the display state of the information displayed on the display unit when the pressure detected by the pressure detection unit has decreased by an amount greater than or equal to a predetermined ratio within a predetermined time, and wherein the operation control unit determines selection of a focused object of the object list when the pressure detected by the pressure detection unit has decreased by an amount greater than or equal to a predetermined ratio within a predetermined time. a contact detection unit for detecting contact of an operation body with a display surface of a display unit on which information is displayed; a pressure detection unit, provided on the display unit, for detecting a pressure at which the operation body presses the display surface of the display unit; and an operation control unit for changing a display state of the information displayed on the display unit in a forward or reverse direction on the basis of an amount of pressure detected by the pressure detection unit until the operation body makes contact with and is separated from the display surface of the display unit, and wherein, when an object list in which a plurality of objects are arranged in one direction is displayed on the display unit, the operation control unit: scrolls the object list in the forward direction step by step every time the pressure detected by the pressure detection unit exceeds one or more pressure thresholds set step by step, and scrolls the object list in the reverse direction, which is a direction opposite to the forward direction, step by step every time the pressure detected by the pressure detection unit falls below the pressure thresholds set step by step, wherein the operation control unit ends a change in the forward or reverse direction of the display state of the information displayed on the display unit when the pressure detected by the pressure detection unit has decreased by an amount greater than or equal to a predetermined ratio within a predetermined time, and wherein the operation control unit determines selection of a focused object of the object list when the pressure detected by the pressure detection unit has decreased by an amount greater than or equal to a predetermined ratio within a predetermined time. scrolls the object list in the forward direction step by step every time the pressure detected by the pressure detection unit exceeds one or more pressure thresholds set step by step, and scrolls the object list in the reverse direction, which is a direction opposite to the forward direction, step by step every time the pressure detected by the pressure detection unit falls below the pressure thresholds set step by step, wherein the operation control unit ends a change in the forward or reverse direction of the display state of the information displayed on the display unit when the pressure detected by the pressure detection unit has decreased by an amount greater than or equal to a predetermined ratio within a predetermined time, and wherein the operation control unit determines selection of a focused object of the object list when the pressure detected by the pressure detection unit has decreased by an amount greater than or equal to a predetermined ratio within a predetermined time.
