DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing technique for a pen-type computer provided with an editing symbol recognition technique. In particular, it relates to an operating system for pen input (pen OS).

[0002]

2. Description of the Related Art When a general computer creates a document or the like, it reads and operates the software for creating the document. This software is an application program, and the input operation at this time is performed by a keyboard and a mouse. By the way, a computer that performs an input operation of the computer with a pen has been proposed.

In this computer, instead of a keyboard and a mouse, a position is designated with a pen, and characters input and edited by recognizing characters and editing symbols (proofing symbols, gestures) written with the pen. In editing using an edit symbol, a method of designating an editing position by a writing position and designating an editing type by a writing shape is generally used.

Japanese Patent Application Laid-Open Nos. 5-225399 (G06K9 / 62), 61-107468 (G06F15 / 20), and 64-64 No. 41081 (G06K9 / 62), Nikkei BP's magazine `` Nikkei Electronics, 1991.4.15 (no.525) '' 115p-133p `` Handwriting input OS
It is well known and described in "Birth". By the way, the actual pen input computer is divided into two.

One is to operate only a specific program using a function dedicated to pen input, a library, or the like. The other one can operate an existing application program using a keyboard and a mouse as input means without changing a pen as input means. In the former, which operates only a specific program, there is one that determines an editing position for each editing symbol and edits the editing position.

One example is shown in FIG. FIG. 1A shows an example of an edit symbol for character insertion, and FIG. 1B shows an example of an edit symbol for blank insertion. Respectively,
H indicates a handwriting and M indicates a previously input character. P indicates an editing position. In the case of FIG. 1A, generally, when a character is written in a character entry box (not shown), the character is recognized and inserted into the editing position.

In the case of FIG. 1B, a blank is inserted at the editing position (P), and the character string to the right of the editing position (P) moves right by one character. In a program dedicated to pen input that does not operate an existing program, the editing position is determined for each editing symbol, and editing at that position is performed by using a specific program such as a dedicated function or recognition library. realizable.

However, in this example, of course, the keyboard,
Existing application programs that use a mouse as input means cannot be used. For this reason, the pen OS for operating the existing application program with the pen is
It is considered. FIG. 2 shows a screen (D) of an example of a computer operated by the pen OS.

The character input window (W1) forms a character entry frame. Editing is performed by writing an editing symbol with a pen in a window (W2) for an application program. The pen OS converts pen input into keyboard input and mouse input.

It is to be noted that converting pen input and supplying it to an application program in this manner is disclosed in
No. 7478 (G06F3 / 03), Japanese Unexamined Patent Publication No. Hei 5-127824 (G06F3 / 03)
It is well known and described in 3). That is, US Micr
In an actual pen OS such as “software for Windows for Pen Computing”, the pen and handwriting coordinates must be in the same format as the mouse in order to operate the existing application program that targets the keyboard and mouse for the input operation device with the pen. By outputting to the application program and outputting the recognition result of the edit symbol to the application program in the same format as the key input, the keyboard with the pen,
Mouse emulation has been done.

However, when an editing symbol is written with a pen,
First, the application program is notified of data indicating that the mouse button was pressed at the position where writing of the edit symbol was started, that is, at the position where the pen was down. as a result,
The application program moves the cursor for character editing to the character coordinates (line, column) corresponding to the position (mouse coordinates) where the editing symbol starts to be written.

Thereafter, the editing symbol is recognized, and data indicating that a key having the same content as the editing content as the recognition result is pressed is notified to the application program.
The application program performs editing based on the edited content. As described above, in the case where the existing program for the keyboard and the mouse is operated with the pen, the position where the writing of the editing symbol is started is the editing position.

FIG. 3 shows an example of editing by this editing method. Figure 3
(a) and (b) show the writing of a symbol for inserting a character and the editing result thereof, and FIGS. 3 (c) and (d) show the writing of a symbol for inserting a blank and the editing result thereof. M indicates an already-input character, H indicates a handwriting of an edit symbol, P indicates an edit position (mouse coordinates), and Q indicates an edit position (character cursor position) to be actually edited.

When a character is input after FIG. 3A, the input character becomes a character string indicated by N as shown in FIG. 3B and is inserted at the position of Q. As in the example of FIG. 3, when the writing start position (P) of the editing symbol is a character coordinate position slightly deviated from the editing position intended by the writer, editing different from the intended editing is performed. This tendency becomes more remarkable as the display size of characters becomes smaller and the characters and line pitches become narrower.

[0015]

As described above, if the writing start position of the editing symbol is fixed at the editing position, there is a problem that the editing cannot be performed as intended by the scribe. When using an existing application program for the keyboard and mouse with the pen,
It is desirable to determine an editing position for each editing symbol and to edit the editing position.

An existing application program for a keyboard and a mouse is not originally designed to be edited with an editing symbol, so that an editing position cannot be set. An object of the present invention is to determine an editing position for each editing symbol even in a pen OS for an existing application program, and to cause the editing position to be edited.

According to the present invention, when an application program using a keyboard and a mouse as input means is operated by a pen, editing by a handwritten edit symbol at a position intended by a writer is realized.
