FIELD: physics; computer engineering.
SUBSTANCE: invention relates to an information input/output method. Provided is an information input/output method, comprising steps for: defining as a block a rectangular area of a square or a rectangle, of a medium surface such as printed matter; while straight lines in a vertical direction and a horizontal direction configuring a frame of the block each are defined as a reference grid line, providing a virtual reference grid point at predetermined intervals on the reference grid line; placing a reference grid point dot on a virtual reference grid point; connecting the virtual reference grid points to each other and defining a straight line parallel to the reference grid line as a grid line; defining a point of intersection of grid lines as a virtual grid point; generating a dot pattern by arranging one or several information dots, each at a distance and direction from the virtual grid point; reading the dot pattern as image information using an optical reading device; numerically valuing the dot pattern; and reading and outputting information corresponding to the numerically valued information from storage device.
EFFECT: possibility of fast provision of information from a dot pattern.
