Abstract

PURPOSE:To improve the operability of a character input device by displaying a holograph pattern of handwritten characters and a character pattern sent from a memory part on the same display screen in response to the input data. CONSTITUTION:At the outset, the coordinate data is supplied from a coordinate input means 12 of an input means 1 by a pen. The means 12 is divided previously into plural functions. A coordinate deciding means 13 receives the input coordinate data and decides an area where the data is included from the coordinate value. If the coordinate data is included in a handwritten character input area, the means 13 sends the input coordinate data to a character recognizing means 2 and a display control means 3. The means 2 starts the processing needed for recognition of characters. At the same time, the means 3 displays the coordinate data fed continuously to a display means 5 successively together with the display of holograph for handwritten characters. While the means 13 sends one of character codes set previously to a means 3. The means 3 reads a character pattern corresponding to the character code out of a character pattern memory part 4 and displays it to the means 5.

Description

[Detailed Description of the Invention] Field of Application in Industry The present invention is directed to the use of character recognition through online handwritten character recognition;
The present invention relates to a character input device for word processors, personal computers, etc., which can be input using any method in combination with other character input methods.

Conventional Structure and Problems Recently, a method using online character recognition has been put into practical use as a Japanese character input method. As a conventional example, there is a method in which a piece of paper is placed on the input surface and the data is drawn using a ballpoint pen. In this method, paper is used to display the button marks, so it is necessary to replace the paper frequently, and the display device (for example, a CRT display) that displays the handwriting display surface and the characters of the recognition result is very expensive. It is inconvenient because it is located far away from the target, so you have to change your line of sight every time you read the text.

In addition, as another method, d2 is a system that closely implements an electromagnetic induction tablet and an EL (cold-thermal luminescent) Nice Play, so that the handwriting of one character and the character pattern of the recognition result of the completed character can be displayed on the same display screen. In this example, you can input characters using online character recognition, but if you forget the character you want to input (kanji), there is no other way to input characters. It is a flight.

Purpose of the Invention The present invention solves the drawbacks of the conventional example described above, and represents the handwriting of 1,11 sentences and the characters of the recognition results in the same table. Input handwritten characters with images＼1. The purpose is to provide N and others with a 10-kiro character input device that allows them to directly input characters using character codes.

Structure of the Invention The character input device of the present invention includes an input element 19 that identifies the input and outputs it as character code 11''1/) Qj coordinate data 7; (a character recognition means that inputs a vote data, identifies characters, and outputs the character code of the identification result; a III data character code sent from the input means; and the character recognition means 1.) Display control means for inputting the sent character codes and outputting display data with store names for each; display means for displaying this in response to the output from the display control means; and character pattern data responsive to the character codes. and a character pattern storage section configured to store character pattern data and send out character pattern data in response to a request from the display control means, and when the display control means inputs coordinate data from the input means, the display control means inputs coordinate data to the input coordinate data. In response, the display control means operates to display handwriting on the display means, and when a character code is supplied from the input means or the character recognition means, the display control means displays a character pattern in response to the supplied character code. The data is read from the ^111 character pattern storage section and sent to the display means, and the display means is configured to display the supplied character pattern, thereby displaying the handwritten characters on the same display surface. Since the character pattern of the recognition result and the code-input character pattern can be displayed, it is possible to obtain a character input device that allows character input without shifting one's line of sight.

This is a display means that receives output from and displays it.

FIGS. 2 and 3 are partial block diagrams showing configuration examples of the input means 1, respectively. In FIG. 2, 12
13 is a coordinate input means, and 13 is a two-letter code after determining the coordinate value.
This is a coordinate determination means that outputs either a control signal or coordinate data.

In FIG. 3, 12 is a coordinate input means, 14 is a code input means for inputting character codes and other control codes, 1
Reference numeral 5 denotes input code determining means for determining the input code, sending a character recognition means control signal to the character recognition means 2, and sending a seven character code to the display control means 3.

In the following description, it is assumed that the input means 1 is composed of a coordinate input means 12 and a coordinate determination means 13 as shown in FIG. As the coordinate input means 12, there is a method for inputting using a pen at the top and bottom of a transparent tablet. As such a coordinate input device, parallel conductive wires are embedded in a transparent acrylic board.

Due to the magnetic field generated by the current flowing through the conductor.

There is an electromagnetic induction method that reads the coordinates by electromotive force generated in a coil embedded in the pen.

As the display means 6, a liquid crystal display can be used. As a result, as shown in FIG. 4(d).

The display means 5 can be arranged under the coordinate input means 12 in an overlapping manner.

The operation of the character inserting blade device of this embodiment configured as described above will be described below.

There are known methods for matching the 1'li mark, and any method may be used. In parallel with this, the display control means 3 to which the coordinate data has been input outputs the input coordinates in relation to the coordinates of the corresponding point on the display surface of the display means 5, thereby performing two-way display. The handwriting of handwritten characters is displayed by sequentially displaying the coordinate data inputted in a similar manner on the display means 5. In other words, as shown in FIGS. 4(a) and 4(b), when the pen moves in the handwritten character input area 63 of the superimposed coordinate input means 12, the image appears on the liquid crystal display under the tablet as if it were four lines of paper. Handwriting appears as if you are writing.

Next, a case where the input coordinate data is included in the control code input area 61 will be described. In this case, coordinate determination means 1

Finally, the case where the input coordinate data is the character code input area 62 will be explained. In this case, the coordinate determination means 13 sends any one of the character codes preset according to the input coordinate values to the display control means 3 and as an output to the outside. The display control means 3 that has input the character code reads out a character pattern corresponding to the character code from the two-character pattern storage section 4 and displays it on the display means 5 in the same way as when the character code of the recognition result is input from the character recognition means 2 described above.
to be displayed.

Next, a case where the input means 1 is configured by the coordinate input means 12, the code input device 14, and the input code determination means 15 will be explained. As the coordinate input means 12, the transparent tablet of the above-mentioned example is used.

In this case, the tablet is used only for inputting handwritten characters.

A general keyboard can be used as the code input means 14. The input from the keyboard is identified by the input code determining means 15 into a character code and a control code (including a character recognition means control signal).

The character recognition means control signal is sent to the character recognition means 2, and the other codes are outputted to the outside. The operations of the following sections are similar to those in the previous embodiment.

As is clear from the explanation in Section 2 of ``Advantages of the Invention'', in the character input device of the present invention, which includes input means 2 character recognition means 1 display control means 2 display means 1 character pattern storage section, display control means t;
In response to the input data, it is possible to control the display of character patterns supplied from the character pattern storage section and display them on the same display surface. As a result, when inputting handwritten characters, the i1 mark and the character pattern of the recognition result are displayed on the same display screen, and in combination with a character input method other than handwritten character input, a character input device with good operability is realized. 7, can
