<p><P>PROBLEM TO BE SOLVED: To detect a designated position in a display device by a new mechanism different from the conventional one. <P>SOLUTION: Figure 6 is a figure showing one example of device identification information formed in a first pattern sheet, X-coordinate and Y-coordinate. Circles represented by oblique lines in the Figure mean black dots or white dots. In an area A11, black dots and white dots representing device identification information represented by 16-bits in addition to a second pattern sheet described later are formed. An expansion area A12 adjacent, on the right, to the area A11 is used when needed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
