Abstract
A surface including: a plurality of visually detectable marks, wherein the visually detectable marks include: a first group of grid marks forming a grid and a second group of information marks encoding information based on positions of information marks of the second group of marks relative to the data page, wherein grid marks are less than 45% of the visually detectable marks on the surface.

A surface with embedded information comprising:
- a plurality of visually detectable marks, wherein the visually detectable marks comprise:
- a first group of grid marks forming a grid and
- a second group of information marks encoding information based on positions of marks of the second group of information marks relative to a data page, wherein grid marks are less than 45% of the visually detectable marks on the surface.
A surface with embedded information comprising:
- a plurality of visually detectable marks, wherein the visually detectable marks comprise:
- a first group of grid marks forming a grid;
- a second group of information marks encoding information based on positions of the information marks in the second group of information marks relative to the data page;
- and
- a third group of orientation marks in each data page, wherein the third group of orientation marks provide orientation information for the grid.

A surface with embedded information comprising:
- a plurality of visually detectable marks, wherein the visually detectable marks comprise:
- a first group of composite marks, the first group of composite marks forming a data page and the first group of composite marks indicating an orientation direction for the visually detectable marks on the surface, and
- a second group of information marks,
- wherein each data page contains an array of data grids, one data grid in each data page contains a composite mark, other data grids in each data page contain an information mark, and the information marks encode information based on the position of the information mark within the respective data grid containing the information mark.
