Abstract

PURPOSE:To make both of a command input and character input possible through the same input operation, by making inputted information discriminable whether it is character information or command information by changing the inputting position against a data displaying means or input means. CONSTITUTION:The operator of this device can input a command for data edition with an input pen 16 as in the case of inputting ordinary characters. When, for example, he inputs command symbols, such as codes (a) and (b), to prescribed positions on ruled lines of the table shown in the figure, desired commands can be inputted. When the command symbols are inputted to the positions on the ruled lines, he inputs the commands with prescribed strokes as shown in Fig. A and B. When the above-mentioned inputting operations are made, a CPU 11 discriminates that the inputted data are command information. Accordingly, a command input and ordinary character input can be made through the same inputting operations.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information input/output device, and particularly to an information input/output device for editing displayed character data.

[Prior Art] Information input/output devices that process data in tabular format have been known in the fields of accounting calculations, scientific and technical calculations, database processing, and the like. The operator interface device used in this type of device is often comprised of a display device such as a CRT display and a keyboard such as a JIS board.

This kind? With Jffi, display data in table format on the display device, move the cursor to the desired position in the table using the cursor movement keys on the keyboard, and select the character at the cursor position.
The main method used is to edit symbols.

When moving a cursor using a keyboard, there is a problem in that the cursor movement keys are often far from the home position of the keyboard, making blind touch operations difficult. Furthermore, devices are known that are designed to allow the cursor to be moved without moving from the home position using a control key sequence, but these devices have the problem of being complicated to operate and difficult to master.

In addition, in the method of moving the cursor manually using keys,
In either case, when moving the cursor over a long distance, you have to manually press the key many times, and with methods that allow you to press keys continuously, the cursor overruns beyond the desired stopping position. , and it was difficult to accurately control cursor movement.

[Problems to be Solved by the Invention] In view of this point, techniques have also been used to facilitate cursor movement by making the cursor jump to a desired position using a digitizer, pointing device such as a mouse, etc. There is.

However, when considering the task of repeatedly moving the cursor, entering characters, and making changes using such a device, it is easy to operate and master the cursor movement itself, but as with the cursor movement keys, the keyboard and pointing device are The problem is that the overall operation is complicated and work efficiency is low because of the hassle of changing hands.

It is conceivable to input characters only using a pointing device by displaying a menu, etc., but with such an input method, it is impossible to expect high-speed character input using a keyboard, so there is a similar problem that work efficiency I is reduced.

Although tabular data processing has been considered below, similar problems arise in devices such as word processors that process data that is arranged in one or two dimensions on a display by moving a cursor and manually pressing keys.

In addition, although the above example shows character input and cursor movement,
A similar problem occurs even when other commands such as character or line deletion, insertion, and other editing commands are repeatedly input in addition to character input.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, in an information input/output device for editing displayed character data, there is provided a data display means and a superimposed device on the data display means. a data input means which is arranged to input handwritten character information or command information for control; and information inputted from the input means according to the input position relative to the data display means or input means. Determine whether the input data is character information or command information, and if the input data is character data, display the input character information on the data display means, and if the input data is a command, display the input data based on the input command. A configuration was adopted that provided a means for controlling the editing of information.

[Operation] According to the above configuration, by changing the input position with respect to the data display means or input means, it is possible to instruct the control means whether the input information is character information or command information, and the same input operation can be performed. You can input commands and characters using the .

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 shows the structure of an information input/output device employing the present invention. As shown in FIG. An input/output device 13 is provided for inputting information and for inputting character information on the same display surface as the input surface.

The input/output device 13 includes a display 14 composed of a liquid crystal display, a CRT display, etc., and the display 1
It is composed of a digitizer tablet 15 placed on top of the digitizer tablet 4.

The digitizer tablet 15 is configured as a digitizer tablet of a resistive type, an ultrasonic type, etc., and can input handwritten characters or command information on the input surface using an input pen 16 configured according to the input method. There is. Furthermore, since the digitizer tablet 15 is transparent, the operator can visually check the display on the display 14 through the digitizer tablet 15.

Display control of display 14 and digitizer tablet 15
The input control of the C
Performed by PUII.

A device 12 consisting of a ROM, RAM, or a magnetic disk device is connected to the CPU II. The ROM of the storage device 12 stores control programs, necessary control constants, etc., and the RAM. The magnetic disk device stores input character information or character information to be edited.

The input and editing processing performed in the above configuration may be of any type, such as word processing or tabular data processing, as long as the processing is performed by arranging data on a display screen in two dimensions. , Below, tabular data processing will be illustrated.

In the tabular data processing of this embodiment, the input pen 16
The handwritten character information input into the digitizer tablet 15 is recognized by the CPtJll, converted into a predetermined character code, and stored in the storage device l2. That is, character information is processed not as image data, but in the form of character codes, which have less redundancy.

FIG. 2 shows the input and display screen of the input/output device 13 of FIG. 1 during processing. As shown in the figure, character data is output on the display l4 in a table format in which the character data is surrounded by ruled lines.

The character data is input by hand to the digitizer tablet 15 using the input pen 16. CPU1
1 performs character recognition on input information from the input pen 16 using a known method such as a stroke method, converts it into a character code such as a JIS code, and causes the display 14 to display font information corresponding to the character code.

This display is visually recognized via the digitizer tablet 15. The simplest table showing correspondence between names and telephone numbers of individuals is shown here.

On the other hand, commands for data editing are also input using the input pen l6. For example, a symbol a. Command input is performed by inputting a command symbol such as b.

The command symbol is entered at the ear edge position of the table, and
By inputting with predetermined strokes as shown in FIGS. 3(A) and 3(B), it is indicated to the CPU II that it is command information rather than character information.

Here, the command symbol "a" made up of 7 characters lying horizontally in FIG. Similarly, it is drawn in the direction of the arrow from S3 toward the end point S4.

Here, the command symbol a instructs to insert a line, and the command symbol b instructs to delete a line. In other words, the operator
By entering the command symbol a as shown in the figure, the first
You can instruct that a blank item for one line be inserted between the items for Mr. ``Sakaguchi'' and Mr. ``Kato'' in row 1. in this case,
The input position is the horizontal π separating the two items you wish to insert.
Above the line.

Also, by inputting command b as shown in Figure 2, you can instruct the user to delete the third line, ``Tenkiyoho''. In this case, the input position is on the vertical ruled line at the left end of the item desired to be deleted.

Figure 4 shows the control program for the CPU 1l to enable the above inputs. FIG. 4 is stored in the ROM of the storage device 7912.

When the coordinates are input from the digitizer tablet 15, the CPU II starts the procedure shown in FIG.

In step 1 in FIG. 4, coordinate information (X, y) of the input point S from the digitizer tablet 15 is stored at a predetermined address. This storage area S is constituted by a register of the CPU II or a predetermined recording area of the storage device a12.

In step 2, it is determined whether the input point S is inside the ruled line displayed on the display 14. If step 2 is negative, a command has been input, so the process moves to step 3. If step 2 is affirmative, the process moves to step 10 because writing has been done in the table item.

In the command input routine from step 3 to step 9, first in step 3, the coordinates of the first input point are ignored and the trajectory of the input pen 16 is recognized from the next input point.

In the determination steps of steps 4 and 7, the input trajectory is the command symbol a shown in FIGS. 3(A) and 3(B).
, b. If the command symbol a commanding the insertion of a zero line is input, the process moves from step 4 to step 5. If the command symbol s commanding the deletion of a line is input. , move from step 7 to step 8. If step 4.7 is negative, it is determined that no valid command has been input. If a larger number of command symbols are used, a command determination routine for this purpose may be provided after step 7.

When an insertion command is input, in step 2, the position of the desired item is recognized from the coordinate values of the starting point S1 and ending point S2 of the command symbol in FIG.

Next, in step 6, the item line displayed below the target line is shifted down on the display 14 by one line, and a blank line is inserted at the position of the line.

On the other hand, when a deletion command is input, in step 2 8, the desired line is recognized from the coordinates of the starting point S3 and ending point S4 of the command symbol shown in FIG. 3 CB).

Next, in step 9, delete the purposeful content and
Shift the items following the row upwards on the display 14.

The display control described above is performed on the display 1 provided in the storage device 12.
This can be done by processing the display data area No. 4 using a known method.

On the other hand, in character input after step 10, first, in step 10, the item position K in the table to be input is recognized from the coordinate value of the input point S, and then in step 11, the input position is recognized from the continuing input trajectory using a known method. Recognize textual information.

In step 12, the input and recognized character code is entered in item K. At this time, characters may be inserted into the item, or characters that have already been input may be deleted by overwriting.This switching may be done by setting a switch (not shown), etc. It's a good idea to leave it there.

As described above, commands can be input by inputting command symbols with the input pen 16 above or outside the ruled lines of the table, and if characters are input within the π line, the input characters are recognized. Entered into the table items.

That is, according to this embodiment, both character input and editing commands can be input using the manual pen 16 without changing the operating member, so that work efficiency can be greatly improved.

Although an example of a telephone number table (telephone directory) has been shown above, the above structure is not limited to this, and can also be used for table data processing for accounting calculations as shown in FIG. The table displayed on the display 14 in FIG. 5 shows the monthly sales of each branch, and includes a column for the monthly total of each store's sales.

In this embodiment, the total amount for the month is calculated by inputting a command symbol (=) in a range inside the ruled line of a desired item in the total column, and the total amount for the month is displayed in that column.

In this way, it is possible to execute a specific editing command by inputting a command symbol, even in the case of spreadsheet calculations. Here, the editing command has meaning when it is input inside the total column rather than outside the ruled lines.In the hardware configuration as shown in Figure 1, -
This can be carried out using the same control procedure as shown in FIG.

Although data processing using a table has been described above, the technique of the present invention can be similarly implemented in any device that arranges character data on a display surface and performs editing processing on the data.

For example, in editing processes such as word processors, especially when proofreading text that has already been input, entering editing commands outside the text display area
You can perform operations such as deletion and insertion.

It goes without saying that the same technique can also be applied to editing character strings arranged in a one-dimensional direction, such as editing a command line of an operating system.

[Effects of the Invention] As is clear from the above, according to the present invention, in an information input/output device for editing displayed character data, a data display means and handwritten character information arranged over the data display means are provided. or a data input means capable of inputting command information for control, and a data display means or an input position of the information input from the input means to determine whether the input information is character information or command information. If the input data is character data, the input character information is displayed on the data display means, and if the input data is a command, the displayed information is controlled to be edited based on the input command. By changing the input position relative to the data display means or input means, it is possible to instruct the control means whether the input information is character information or command information. It is possible to provide an information input/output device with excellent operability that allows command input and character input through input operations.
