Description

Detailed Description of the Invention (1) Description of the field to which the invention pertains The present invention provides a handwriting input function that can recognize and input handwritten characters and figures on a tablet board to create a printed document. It is about a word processor equipped with.

(2) Detailed explanation of the prior art and invention The conventional device of this type has a separate structure in which the tablet board on which handwritten characters and figures are written and the display on which the marks and recognition results are displayed are independent. . Therefore, in order to confirm that handwritten characters and figures have been correctly recognized and input, it is necessary to alternately look at the tablet surface and the display surface. This seriously hindered input operations and made operability worse. A solution to improve this operability is to create an integrated structure by stacking the display device under the tablet board. 1. For #11 of handwritten letters and figures, the recognition results are displayed in print directly below. do it.

Another significant drawback of this type of conventional equipment is.

Low efficiency in editing documents that have been input KToi. With conventional word processors, when editing a document or editing a document, you move the cursor to specify the location of the character to be corrected or inserted, so you need to check the current position of the cursor and the position of the target character in the document. However, there are some problems with operability, such as giving instructions to move the cursor while using the cursor. To solve this problem, use the above-mentioned input/output device that combines a tablet and a display.1 Since it is possible to directly specify any position in the displayed document on the tablet board, editing Operation is significantly improved. Furthermore, when using a tablet with such an integrated structure, it is possible to maintain the format of the output format displayed on the display and the format of the input format on the tablet, while also allowing arbitrary formats (for example, A
4. It is easy to change to B5 fathom). Therefore, the scribe.

From the input stage, you can simply enter text according to the input format that appears on the tablet, and you can obtain the same operability as creating a document while laying out the layout on the paper. Furthermore, using this type of input/output device, it is possible to rearrange the many command keys for operations at once to make it easier for the scribe to use. This can greatly contribute to improving operability during zero editing.

(3) Purpose of the Invention The present invention provides an integral structure in which a transparent or nearly transparent plate-like coordinate input tablet board is directly fixed on the display surface of a display device as a means for inputting and displaying characters and figures. coordinate input/output device (for example, patent application 18ss-
This book is characterized by the application of ``xt2s2g'' to a handwritten input word processor, and its purpose is to improve the operability of a handwritten input word processor.

(4) Description of structure and operation of the invention FIG. 1 is a block diagram showing an outline of a handwritten input word processor of the invention, and FIG. 2 is a diagram showing an example of a screen displayed on a display. In the figure.

1 is a stylus/pen, 2 is a transparent tablet board.

3 is an electroluminescent display, 4 is an online handwritten character recognition device, 5 is a document editing device, 6 is a printer, 7 is a coordinate value conversion device, 8 is a main control device, 9 is a function specification area, and 10 company candidate character display Department.

Reference numeral 11 indicates a character/figure entry section, 12 indicates a recognition result, 13 indicates handwriting of handwritten characters, and 14 indicates a character/symbol keyboard. First, an overview of the word processor shown in FIG. 1 will be explained.

On the tablet board 2, write characters in the character frame of the character/figure entry section 11 displayed on the display 36.
The characters are cut out for each character frame, and coordinate signals representing the handwriting of the characters are input to the online character recognition device 4. The online character recognition device can be constructed using known technology. ia! The numbers 12 are displayed one after another in printed letters in the corresponding character frames of the 0 character/figure entry area 11. Furthermore, the chain trace 13 of the character being written within one character frame is displayed moment by moment on the display 3. In addition to inputting handwritten characters, it is also possible to input preset characters, symbols, etc. by pressing the single character/symbol keyboard 14 with the stylus Ben 1.

Il#4 Recognized characters can be modified as follows. Stylus Ben 1
When a "candidate key" preset in the function designation area 9 is pressed with the stylus Ben l, a plurality of similar characters from the second rank onwards are displayed on the candidate character display section 10. Therefore.

If there is a correct character among the displayed candidates, press it with the stylus Ben 1 to input it, and it will be recognized by V4 and the circled character can be corrected. If it is not included in the candidates, enter the character again in any blank space of the character/figure entry section 11, or input the corresponding character from the six character/symbol keyboard 14.

In this way, if you write characters on the tablet board 2 using a pen that does not require ink, the 9 character handwriting 13 and the recognition result 12 will be displayed one after another on the display 3. An easy-to-operate handwritten character input form that is unnecessary and allows you to check the correct recognition input of round characters while writing is realized.

In addition, due to the distance between the tablet board's surface and the display surface, there is a parallax during one handwriting, but in order to minimize this shadow, the position value was changed. The display position of handwriting, etc. can be arbitrarily changed using a circuit (for example, *1ilH56-112528).

Next, an example of one editing operation will be explained using FIG. 2.

The case of editing, deleting, and inserting a document displayed in the character/graphic entry section 11 will be explained as an example.

To make a correction, press the position of the character you want to correct with stylus pen 1, then press the "Correction" key in function specification area 9 with stylus pen L to erase that character, and then write a new character in the blank character frame. Execute by entering characters.

To delete, specify the character you want to delete by pressing it with stylus pen 1, and then press the "Delete" key in function specification @#9.Also, at the same time as deletion, the blank character area will be Columns are displayed sequentially.

For insertion, use the stylus to position the character to be inserted.
This is done by specifying with the pen 1, then pressing the [insert] key in the function designation area 9 with the stylus pen 1, and writing the character in any margin of the character/figure entry area 11 after the stylus pen 1. After performing the insert.

The characters written for insertion will be deleted.

If you use such an input/output device that has an integrated writing surface and display surface, if you want to create a blank area in your text, use the stylus pen 1 to draw a circle around the blank area you want to set.
Press the "blank" key in the designated area 9.
Much easier to implement. The command keys in the function designation area 9 used for document editing are determined by causing the recognition device 4 to wwR a symbol corresponding to the command key.

It is also possible to substitute nine handwritten symbols written in a document. All such document editing operations are carried out by a program that returns to the main controller 8. In this way, an input/output device (for example, 4IM Showa 5G-112528)
By applying 9 to the handwritten character input section and display section, the poor operability during editing in conventional handwritten negative input word processors can be significantly improved.

(5) Description of effects As explained above, according to the present invention, handwritten characters and
The handwriting of figures, their lai recognition results, and the created document can be displayed on a display integrated with the tablet board. You can get points.

■ There is no need for paper to write letters and figures.

■ Since the handwriting of letters and figures can be confirmed on the tablet board, the scribe can feel as if he or she is drawing electrically on paper with a pen with 4 ink, and there is no need to use ink without using writing forms. Even if you write directly on the tablet board with Nope/, there is no discomfort in the sense of writing.

■ The recognition results of handwritten characters can be checked instantly on the tablet board, making it easy to correct input errors, and improving the ease of use found in conventional word processors that recognize and input handwritten characters. can be significantly improved.

■ You can check the created document in the same format as the one that can be output on the tablet board, so when editing a document, such as making corrections or changes, you can directly specify the characters you want to correct using the writing pen, making editing operations easier. Naturally improves work efficiency.

■ Parallax based on K (difference in thickness of tablet board and screen display surface) can be adjusted to the minimum according to the scribe, so even if the tablet board is thick to a certain extent, there will be no discomfort in operability.
