<p>PROBLEM TO BE SOLVED: To provide a method for dispensing with remodeling of a personal computer without mounting an exclusive substrate in a method for establishing coordinates by touching a CRT picture with a write pen. SOLUTION: This system creates a coordinate window on the CRT picture, converts numerical information into color data by a program, reads the color data with an optical electronic pen and converts it into numerical data. Consequently, both conversion of the numerical data into the color data on the coordinate window and restoration of the color data to the numerical data with the optical electronic pen can be performed by the program.</p> |
