Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a document creation / editing apparatus for inputting and editing characters and figures in a word processor, a workstation, or the like.

(Prior Art) Conventionally, a command for inputting or editing a character or a figure has designated a fixed area on the keyboard or near the outer frame of the screen with a position input device such as a mouse. Sixth
The figure is a diagram showing an example of editing of characters, and shows a state in the middle of insertion. A character input device such as a mouse is displayed at the position where the 61 character is inserted by displaying the character input by the Kana-Kanji conversion on the keyboard in the 62 input area, and at the position of the 63 insertion end command to end this insertion process. It was instructed by moving the cursor and pressing the button.

As described above, the conventional technique is based on the premise that the input area and the position of the insertion end command are close to each other as shown in FIG. However, as shown in FIG. 7, in a device in which a transparent tablet is arranged on a liquid crystal display and the display unit and the input unit are integrated, the character input method is different,
When the conventional technology is applied as it is, a problem occurs. In a device such as that shown in FIG. 7, when a character is written on a transparent tablet without a keyboard, which kanji is written is recognized from the group of position coordinates at which the character is written. In FIG. 8, the character to be directly inserted is written in the input area 81, the characters are inserted in order, and when the insertion is finished, the insertion end command 82 is pressed. Fig. 9 shows the place 91 where you want to insert and the insert end command 92
When the position is distant, in this case, write a character near 91, the handwriting recognition recognizes the character, and after insertion is done, move the cursor up to the position of 92 to finish the insertion. It needs to be moved and the operability is not good.
That is, it is necessary to write a character input on a screen at a desired position and a fixed command position causes problems.

(Problems to be Solved by the Invention) As described above, according to the conventional technology, when editing a character or a figure, the position where the character or the figure is pointed and the position where the command is arranged are fixed, so that the operability is good. There wasn't. To solve this, place the command near the place where you are inputting or editing. However, placing many commands occupies a large area on the screen,
There is a problem in operability. Therefore, an object of the present invention is to provide a device capable of checking a command that has been input so far in the process of inputting or editing and displaying the next command that can be input next to the place where the inputting or editing is performed. is there.

[Structure of Invention]

(Means for Solving Problems) The present invention relates to an input unit for inputting position coordinates, and a command when the position coordinates from the input unit specify a command area on the display unit. A command execution unit that performs processing, a handwritten character recognition unit that generates a character code when the position coordinate sequence from the input unit is input as a character, and document information using the character code from the handwritten character recognition unit. A display unit for displaying, a unit for identifying and displaying a portion of the document information on the display unit that is to be input or edited, a command rule storage unit that stores command information that has been ordered in advance, and the display unit. And a means for retrieving and displaying command information, which can be used at the time of inputting or editing, in the vicinity of the part to be input or edited in the document information from the command rule storage unit. It is characterized by having.

(Operation) FIG. 2 is a diagram for explaining the operation of the present invention. Second
The outer frame of the figure is the display surface of the liquid crystal display, on which a transparent tablet is arranged as shown in FIG. Since the tablet is transparent, you can see the characters and figures displayed on the liquid crystal display, and you can retrieve the coordinates corresponding to the display screen by entering the position coordinates with the pen on the tablet.

In FIG. 2, a character is about to be inserted into the already written character string, and the insertion position indicated by 21, that is, the position of the character to be edited is highlighted by enclosing.

When the position coordinates are continuously input from the tablet in the enclosed area, it is determined that the connection of the position coordinates represents a character, the handwritten character recognition means obtains the code of the character, and the code is provided at the enclosed place. The character pattern is displayed by and the insertion is repeated by enclosing and enclosing the character string after that to the right.

On the other hand, in the process of the insertion processing, the next command that can be input is found to be the end of the insertion, so that it is displayed as a command under the enclosure as indicated by 22 in FIG. If you enter the position in the command area indicated by 22 instead of writing a character in the box, you will enter the code of the insertion end command.

Even if the character input area of 21 moves, the insertion end command of 22 is displayed immediately below, and when you want to end the insertion, you can move your hand slightly down to achieve the purpose. Thus, the next command you want to press is right next to you, so you don't have to move your hand too much, which greatly improves operability.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of the embodiment apparatus. The position coordinate input unit 1 plays a role of importing the position coordinates into this device.

The command analysis unit 2 manages the control of this device. The handwritten character recognition unit 3 converts the input position coordinate sequence into a character code by assuming that a character is written. The command rule storage unit 4 stores the order of commands, and a part of the contents is shown in FIG. The command display unit 5 plays a role of displaying a command that can be designated next.

The command execution unit 6 is delivered from the command analysis unit. Responsible for executing input or edit commands. Display 7
Plays a role of updating the display on the liquid crystal display according to designations from the command display unit 5 and the command execution unit 6.

An embodiment of the present invention will be described below with reference to the drawings.

The position coordinate input unit 1 plays a role of taking in the position coordinates input from a tablet or the like into this device. The command analysis unit 2 takes in the position coordinates from the position coordinate input unit 8, and the coordinates are stored in the command display position storage unit 8 whose contents will be described later.
Is checked, and if it is in the command area, the code of the command is sent to the command execution unit 6. Further, the command rule storage unit 4 is searched to determine whether or not the input command is expected to input the next character. If a character is expected to be input, a square frame as shown by 21 in FIG. 2 is displayed on the display unit 7 at the input location, and the area is stored in the input position storage unit 9.

Then, the coordinates of the position of 10 dots downward from the lower left coordinates of the input position are stored in the command display position storage unit 8. In the command analysis unit 2, if the coordinates input from the position coordinate input unit 1 are within the area indicated by the input position storage unit 9, the position coordinates are added to the input position coordinate sequence storage unit 10. Register. At this time, if 0.5 seconds or more has elapsed from the input of the previous position coordinate, the handwritten character recognition unit 3 is not additionally registered in the input position coordinate sequence storage unit 10.
To the recognition instruction.

The handwritten character recognition unit 3 reads the position coordinates from the input position coordinate storage unit 9, determines that the connection of the points represents a character, converts it into a corresponding character code by referring to the recognition dictionary 11, and sends the code to a command. Correct to analysis unit 2. At this time, the command analysis unit 2 sends the code returned from the handwritten character recognition unit to the command execution unit 6. The command execution unit performs processing based on the characters sent and the commands such as current insertion and correction, and reconstructs the display. At this time, the display content storage unit 12 is also updated. If the coordinates input from the position coordinate input unit 1 are neither in the command area nor in the character input frame, it is regarded as pointing to a character, the display content storage unit 12 is read out, and displayed anywhere. It is indicated that the character is pointed by reversing the display of the character, etc., and the coordinate of the position of 10 dots downward is set to the lower left coordinate of the display position of the character. It is stored in the command display position storage unit 8.

Next, the command analysis unit 2 instructs the command display unit 5 to check all the commands that can be input next by referring to the command rule storage unit 4 and display the names and frames of all the commands. The command display unit reads the display position from the command display position storage unit 8 and displays the command name and frame at that position. Then, what is displayed is additionally registered in the command display position storage unit.

The contents of the command display position storage section at this time are shown in FIGS. 4 (a) and 4 (b). (10,10) (30,20) are the upper left and lower right coordinates of the position where the insert command is displayed.
It is expressed in the x, y format, and the content is the command name to be displayed.

FIG. 5 is a diagram showing an example of the flow of an embodiment of the present invention. Here, first, a position coordinate sequence is input (step
501). Next, the processing is divided depending on whether the input coordinates are in the command area, in the character input frame, or in other areas (steps 503 and 504).

If it is in the command area, it is converted into a command code, and if the judgment "whether to input a character next" is true, the character input frame is displayed at the position of the character already pointed to, and thereafter The displayed characters are divided and displayed. Then, prepare to display the commands below the input frame, and display the commands that can be input next together. (Steps 506 to 509) Next, if it is in the character input box, the position coordinate string continuously written in the character input box is taken in until the input is delayed for 0.5 seconds (steps 505 and 502), and handwritten character recognition Is converted into a character code by and the character code is displayed. Then, the character input frame is displayed at the next character position, and the characters displayed thereafter are displayed in order. Then, the command display position is updated as in the case of the command code. The commands that can be entered next are displayed together. (Steps 513 to 517) Finally, in other cases, the character displayed at the position coordinate is searched, and the fact that the character is designated is displayed by inverting the color. The command display position is updated in the same manner as the command code according to the position of the character. In addition, the commands that can be entered next are displayed together. (Steps 510-5
12) The present invention is not limited to the above embodiment. For example, the position for displaying the command 22 in FIG. 2 is set to 10 dots downward from the lower left coordinate of the character input frame 21, but another number other than 10 dots may be used, or the size of the character input frame may be changed. If so, a variable value may be taken depending on the size.

Also, although I made it to the bottom, it does not matter whether it is on the left or right, and since it can not be displayed at the bottom, it is below at the top of the screen, above at the bottom, right at the left, right It may be displayed on the left side.

Also, the end of the input of the position coordinate sequence was determined by waiting for 0.5 seconds, but this value may be another value,
It may be determined by entering another area. In short, the present invention can be variously modified and implemented without departing from the scope of the invention.

〔The invention's effect〕

According to the present invention, when inputting and editing a character or a graphic, the command that can be used next is displayed in the vicinity of the operation, and if you point to the one you want to use, that command will be displayed. Is entered. Therefore, it is possible to provide a document creation / editing apparatus with extremely excellent operability.
