Abstract

Coding marks (4) of optically readable coding pattern (3) are arranged across surface (2) of paper (1). Pattern is divided into overlapping partial areas (5a,5b) based on cyclic rotation of number sequence of marks. Surface (2) is divided into code windows, based on dimensions of partial surfaces. Position of windows are estimated, based on distance between overlapping areas of partial surface and window. Independent claims are also included for the following: (a) Computer readable program for determining position of pen on paper; (b) Pen position determining device; (c) Product which enables possibility of determining position
