Document Type and Number:
Japanese Patent JP5763441
Kind Code:
B2
Abstract:
Disclosed is a stream dot technique with excellent convenience, and which defines a plurality of information by means of a dot pattern formed on the basis of benchmark dots disposed in sequence in a line on the surface of a medium without being dependent on the shape of a rectangular region that configures a dot region. When forming the dot pattern, it is possible to form the dot pattern at any location on the surface of a medium or curved surface by means of including a step for disposing a plurality of benchmark dots in sequence in a line according to a predetermined rule; a step for providing a first virtual benchmark line, which links the plurality of benchmark dots; a step for providing a second virtual benchmark line defmed at a predetermined location from the benchmark dots and/or said first virtual benchmark line; a step providing a plurality of virtual benchmark dots at predetermined locations on the second virtual benchmark line; and a step disposing information dots wherein information is defined by the distance and direction from said virtual benchmark dots at an endpoint expressed by a vector and with said virtual benchmark dots as the starting point.
