FIELD: information technology.
SUBSTANCE: invention relates to methods and devices for inputting and outputting information using a dot pattern. A dot pattern is created such that, displacement in the x or y direction is successively generated for each of adjacent information dots on a virtual grid line. For each dot in the x or y direction, displacement is successively generated. As a result, the alternative information dot inevitably lies on the same grid line.
EFFECT: faster and more accurate recognition of dot pattern.
