1. An information input and output method by use of a dot pattern characterized in that, on a medium surface of a printed material etc., a plurality of lattice dots (4) are disposed in a rectangular shape and set as a block, and the blocks are regularly and continuously disposed, and such a dot that 1 piece of the lattice dots (4) which exists in the block was disposed by being shifted unidirectionally is set as a key dot (2), and by setting said key dot (2) as a representative point, they are disposed at a circumference of the key dot (2), and by setting a center which was surrounded by the lattice dots (4) of 4 points as a hypothetical point, and by setting this as a start point, at an end point which was represented by a vector, a plurality of information dots (3) which have various information recognized are arranged in accordance with a predetermined rule by a dot code generation algorithm to thereby generate a dot pattern (1), and a block which configures said dot pattern (1) is imported as image data by a camera, and, from a numerical value which was calculated by digitizing this, information, a program are outputted.
