Pen input processing apparatus
First Claim
1. A pen input processing apparatus comprising:
- displaying means having a screen for displaying information;
inputting means for carrying out inputting by handwriting with respect to said screen;
first memory means for storing editing instructions corresponding to respective handwritten line drawings;
recognizing means for recognizing an inputted editing instruction corresponding to a handwritten line drawing in accordance with the editing instructions stored in said first memory means and the handwritten line drawing when the handwritten line drawing is inputted by said inputting means to overlap information displayed on said screen;
handwriting input area displaying means for displaying a handwriting input area to facilitate character inputting with respect to said screen when said recognizing means recognizes an editing instruction for instructing the character inputting by handwriting, said handwriting input area comprising a plurality of windows;
said inputting means including coordinate information generating means for generating a coordinate information of the handwritten line drawing on said screen;
said first memory means including a first memory area for storing data of a basic stroke of each character;
said recognizing means comparing the basic stroke data with the coordinate information so as to specify which handwritten character is handwritten to said handwriting input, area;
said handwriting input area displaying means including frame data generating means for generating frame data which is required for displaying the plurality of windows in said handwriting input area, one character being written in each one of said windows;
said inputting means including pen means for motivating said coordinate information generating means to generate the coordinate information by touching said screen therewith;
controlling means, connected with said inputting means, for judging whether or not the inputting by handwriting is completed; and
wherein said controlling means judges that the inputting of character by handwriting is completed with respect to a first window of the plurality of windows when said pen means, carrying out the inputting by handwriting with respect to the first window, touches a second window.

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.
