ABSTRACT:
In order to reduce a two-dimensional data structure to a minimum number of bits, a two-dimensional surface pattern is provided, which can be used in particular for identifying an absolute position on the surface and which has a pattern which comprises a SYNC pattern, which is used for synchronization, and a position-dependent code PC(x, y), with the SYNC pattern being variable and being formed in accordance with an already known formation rule.
