Abstract
A product provided with a coding pattern which comprises a plurality of marks, each of which represents one of at least two different values, and which further comprises a plurality of nominal positions, each of said plurality of marks being associated with a nominal position and the value of each mark being determined by its location relative to its nominal position. The invention also comprises use of the product.

42. A product for decoding information, the product comprising:
-
a sensor for detecting a plurality of marks on a surface to obtain associated mark location data, at least a first group of the plurality of marks being arranged on the surface so as to define an invisible raster with predetermined dimensions, and wherein marks in at least a second group of the plurality of marks are displaced from raster locations in a manner encoding information; and a processor for receiving from the sensor at least some of the mark location data, the processor being configured to determine, using the received mark location data, a position of the invisible raster on the surface, and the processor being further configured to decode information based on positions of at least some of the marks in the second group of the plurality of marks relative to locations on the invisible raster. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)

55. A method for decoding information, the method comprising:
-
receiving, by a processor, mark location data from a sensor, the mark location data indicative of locations of at least some of a plurality of marks on a surface, a first group of the plurality of marks being arranged on the surface so as to define an invisible raster with predetermined dimensions, and wherein marks in a second group of the plurality of marks are displaced from raster locations in a manner encoding information; determining, by the processor, a position of the invisible raster on the surface using the received mark location data; and decoding information based on positions of at least some of the marks in the second group of the plurality of marks relative to locations on the invisible raster. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)

69. A computer-readable medium encoded with instructions which, when executed in a processor, perform a method for decoding information, the method comprising:
-
receiving, by a processor, mark location data from a sensor, the mark location data indicative of locations of at least some of a plurality of marks on a surface, a first group of the plurality of marks being arranged on the surface so as to define an invisible raster with predetermined dimensions, and wherein marks in a second group of the plurality of marks are displaced from raster locations in a manner encoding information; determining, by the processor, a position of the invisible raster on the surface using the received mark location data; and decoding information based on positions of at least some of the marks in the second group of the plurality of marks relative to locations on the invisible raster. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82)

83. A product for decoding information, the product comprising:
-
a sensor for detecting a plurality of marks on a surface to obtain associated mark location data, the plurality of marks being arranged on the surface so as to define an invisible raster with predetermined dimensions, wherein each mark is displaced from a raster location in a manner encoding information; and a processor for receiving from the sensor mark location data indicative of locations of at least a subset of the marks on the surface, the processor being configured to determine, using the received mark location data, a position of the invisible raster on the surface, and the processor being further configured to decode information based on a position of at least some of the plurality of marks relative to locations on the invisible raster.
