1. A display control device that controls selection of a plurality of selection items displayed on a display device disposed remotely from a touch operation unit based on operation information input from the touch operation unit, the display control device comprising:

  • a display control processor configured to;

    acquire an operation direction of the touch operation unit as the operation information from the touch operation unit;

    based on the acquired operation information, select a selection item from among the plurality of selection items displayed on the display device, and set a cursor that designates an operation target to the selected selection item;

    when the cursor is set to a predetermined selection item of the plurality of selection items and when, based on a position of the cursor on a display surface of the display device, the selection item is included in a search area that is set in a direction corresponding to the operation direction included in the operation information on the display surface, select a selection item of the plurality of selection items at a position closest to a reference point of the cursor in the direction corresponding to the operation direction as the selection item to be a movement destination of the cursor;

    when multiple selection items of the plurality of selection items are located within the determined search area, select one selection item of the multiple selection items based on a closest distance from each selection item to an origin point determined by the operation information input into the touch operation unit, the origin point designating an initial position of the cursor prior to movement set forth in the operation information;

    when multiple selection items of the plurality of selection items are located at the position closest to the reference point of the cursor in the operation direction;

    calculate a distance on the display surface between the reference point of the cursor and a selection item of the multiple selection items in a direction perpendicular to the direction corresponding to the operation direction on the display surface for the plurality of selection items, andselect a selection item of the multiple selection items that is at a shortest calculated distance as the selection item to be the movement destination of the cursor; and

    when multiple selection items of the plurality of selection items are located at the shortest distance from the reference point of the cursor in the direction perpendicular to the direction corresponding to the operation direction on the display surface;

    set an origin of the cursor to a position different from the reference point in the direction perpendicular to the direction corresponding to the operation direction on the display surface for the plurality of selection items, andselect a selection item of the multiple selection items that is at a shortest distance on the display surface from the origin of the cursor in the direction perpendicular to the direction corresponding to the operation direction as the selection item to be the movement destination of the cursor.
