Information input/output method using dot pattern
DC CAFCFirst Claim
1. A dot pattern comprising:
- defining as a block a rectangular area of a square or a rectangle, of a medium surface such as a printed matter;
while straight lines in a vertical direction and a horizontal direction configuring sides of the block each are defined as a reference grid line, providing virtual reference grid points at predetermined intervals on the reference grid line;
placing reference grid point dots on respective virtual reference grid points;
defining straight lines that connect the virtual reference grid points to each other and are parallel to the reference grid lines as grid lines;
defining a point of intersection of the grid lines as a virtual grid point;
generating the dot pattern by arranging one or a plurality of information dots, each of which has a distance and a direction around the virtual grid point.

Abstract
A dot pattern including a block defined as a rectangular area of a square or a rectangle of a medium face, such as printed matter. A straight line in a vertical direction and a horizontal direction configuring a frame of the block each are defined as a standard grid line. Virtual reference grid points are provided at predetermined intervals on the reference grid line. Reference grid point dots are placed on respective virtual reference grid points. Straight lines that connect the virtual reference grid points to each other and are parallel to the reference grid lines are defined as grid lines. A point of intersection of grid lines is defined as a virtual grid point. A dot pattern is generated by arranging one or a plurality of information dots, each of which has a distance and a direction around the virtual grid point.

7. A dot pattern, comprising:
-
a predetermined number of horizontal reference grid point dots placed at a predetermined interval in a horizontal direction; a predetermined number of vertical reference grid point dots placed in a vertical direction from the horizontal reference grid point dot that is positioned at an end point of the horizontal reference grid point dots; and an information dot in which information is defined by a distance and a direction from a starting point that is an intersection of a vertical direction reference grid line virtually set from the horizontal reference grid point dot and a horizontal direction reference grid line virtually set in a horizontal direction from the vertical direction reference grid point dot. - View Dependent Claims (8, 9, 10)

11. A dot pattern comprising:
-
horizontal reference grid point dots placed in a horizontal direction at a predetermined interval; a predetermined number of vertical reference grid point dots placed in a vertical direction starting from the horizontal reference grid point dot positioned at an end point of the horizontal reference grid point dots and at each predetermined number of horizontal reference grid point dots; a horizontal reference grid point dot additionally placed in a horizontal direction at a predetermined interval at each predetermined number of the vertical reference grid point dots placed vertically from the horizontal reference grid point dot positioned at the end point; and an information dot in which information is defined by a distance and a direction from a starting point that is an intersection of a vertical direction reference grid line virtually set as connecting the corresponding horizontal reference grid point dots and a horizontal direction reference grid line virtually set in a horizontal direction as connecting the corresponding vertical reference grid point dots, wherein a region surrounded by the vertical reference grid point dots and the horizontal reference grid point dots is a block in which a code value and/or a coordinate value is defined.
