Handwriting entry processing system using keyboard and mouse interfaces requiring no modification of an application program

摘要

A handwriting entry processing system used in a tablet type handwriting entry device includes a display unit, an area decision unit, a recognition processing unit, a designation unit and an input/output processing unit. The display unit has a planar display portion and an entry tablet portion, these portions being integratedly constituted in the display unit. The planar display portion displays an output signal from the input/output processing unit. The entry tablet portion constituted by one plane has a first entry portion and a second entry portion, the first entry portion being superimposed on the planar display portion and the second entry portion being located outside of the planar display portion. These entry portions receive a designation signal from the designation unit and output coordinate data to the area decision unit. The area decision unit detects the coordinate data from the entry tablet, transfers the coordinate data to the input/output processing unit when the coordinate data is generated from the first entry portion, and transfers the coordinate data to the recognition processing unit when the coordinate data is generated from the second entry portion. The recognition processing unit receives the signal input from the area decision unit, performs a recognition operation on the handwriting character based on the coordinate data, and outputs the resultant data indicating the characters to the input/output processing unit.
