Summary
| Description | Simplified principle of the Anoto digital pen by CMG Lee. The camera identifies a 6×6 matrix of dots, each displaced from the blue grid (not printed) in 4 directions. The combinations of relative displacements of a 6-bit de Bruijn sequence between the columns, and between the rows gives its absolute position on the digital paper. |
