Abstract
A method for printing a coordinate pattern on a medium includes assigning a pattern to the medium. The pattern is formed on the medium with fixer. A method of calculating a position of an object in relation to the medium using the pattern is disclosed. A predetermined wavelength of electromagnetic radiation is projected onto the pattern and a presence of absence of emittance from the fixer of the pattern is detected. A medium including a substrate having a coordinate pattern overlying at least one side of the substrate is further disclosed. The coordinate pattern includes a means for fluorescing when subjected to a predetermined wavelength of electromagnetic radiation. In another embodiment, a system for forming a substantially invisible coordinate pattern on a medium is disclosed.
