The dot pattern includes: the boundary dots, three direction dots and the code dots. The boundary dots are disposed regularly and continuously to define the blocks. Three direction dots are disposed on centers of three of the blocks to define a direction vector. Each of the code dots is disposed on one of the blocks without the direction dots. The code vectors are defined by the centers of the blocks to the code dots. The information is reproduced by the code vectors and the direction vector. | 10-16-2008 |
