ABSTRACT:
A pen input processing apparatus in accordance with the present invention has a text editing section for displaying on a screen a window through which a character is handwritten only by handwriting on the screen a line drawing indicative of inputting of character by handwriting. The text editing section has a function wherein the name of gesture command corresponding to a line drawing and the character to be edited are displayed by the screen when each line drawing is handwritten with respect to the screen. The pen input processing apparatus has a gesture command judging section for recognizing the gesture command in accordance with a trace coordinate of the line drawing. When the gesture command is recognized and specified, the recognition of the gesture command is informed by a sound. Only one line drawing is assigned to the same editing instructions for one character and a plurality of characters as editing objects. The present apparatus is arranged so as to ignore a minute moving of an inputting pen, thereby making it easy to perform specifying operation of a graphic on the screen for example.
