1. An operation input device comprising:

  • a display;

    a touch panel;

    a generation processor configured to generate pattern information and store the pattern information in a storage, the pattern information indicating relative positions of invalid region shapes with respect to hand shape patterns representing hand shapes, the invalid region shapes representing shapes of a touch invalid region in the touch panel;

    a hand detecting processor configured to detect a position and a shape of a hand that is proximate to the touch panel;

    a collation processor configured to collate the shape of the hand detected by the hand detecting processor with the hand shape patterns included in the pattern information;

    a region setting processor configured to set the touch invalid region based on the pattern information and the position and the shape of the hand detected by the hand detecting processor; and

    a display controller configured to overlay a contour line image that represents a contour of the touch invalid region on a screen displayed on the display, whereinthe generation processor displays, on the display, the hand shape patterns and a plurality of template figures indicating the touch invalid region,the generation processor further rotates, enlarges, or reduces the template figures in accordance with an operation performed on the touch panel,the generation processor further sets a relative position of the touch invalid region with respect to the hand shape patterns in accordance with an operation of dragging one of the template figures to an arbitrary position on the hand shape patterns and dropping it thereon, andthe region setting processor determines a position of the touch invalid region in the touch panel based on the position of the hand detected by the hand detecting processor, and based on a relative position of the one of the invalid region shapes that corresponds to the result of the collation performed by the collation processor.
