Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a word processor, and more particularly, to a word processor which forms a character based on a key input signal and a pen input signal and displays or edits the character.

[0002]

2. Description of the Related Art In a word processor, for example, when moving or copying a sentence in a document by designating a certain range, when a normal keyboard is used, cursors are respectively placed at the start point and the end point of a region to be designated in advance. Move
A general method is to press the "area designation" key.

Further, when a mouse or a pen is used, different methods are taken depending on the device, such as moving while pressing a certain button, and operating the start point and end point of the area with another button. .

[0004]

By the way, when a text is edited, operations such as erasing characters and moving / copying are frequently performed in a predetermined range in the document. However, the conventional keyboard specification method has a problem in that the cursor must be moved in advance and then the area specification key must be pressed, which requires a large number of operation steps and takes time.

The present invention has been made in order to solve such a problem, and it is possible to specify an area in a document by a quick and simple operation, and a user can perform an operation suitable for the application. It is an object to provide a word processor that can be selected.

[0006]

To achieve the above object, the word processor of the present invention will be described with reference to FIG. 1, which is a basic conceptual diagram of the present invention. An input unit 1 for inputting screen input information for processing document data, a storage unit 5 for storing the input data and information, a display unit 3 for displaying the document data and its processing screen, and the screen An area recognition unit 4 that recognizes a specified area in the document data based on input information, and a predetermined command is executed for the recognized specified area, and the storage unit 5, the area recognition unit 4, and the display unit 3 Control unit 2 for driving and controlling each
In the word processor provided with the above, the area recognition unit 4 sets the start point and the end point of the specified area together with the character at the cursor position on the processing screen where the pen is touched, or the pen based on the screen input information. Select either the character on the processing screen where the image for recognizing the area designated by the drawing is located, or the character on the processing screen that has been touched by the pen for a predetermined time or more, and select the start point and It is characterized in that selection recognition means 4a is provided for recognizing characters between the end point and the designated area as the designated area.

[0007]

The start point and the end point of the character string to be the designated area are designated by the selection recognition means based on the screen input information, and the character at the cursor position on the processing screen where the pen is touched or the area designated by the pen is designated. Either a character on the processing screen where the image for recognizing is located or a character on the processing screen touched by the pen for a predetermined time or longer is selected. The character string between the selected start point and end point is recognized as the designated area.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a hardware configuration diagram applied to the embodiment of the present invention.

First, a pen 12 and a keyboard 10 are provided as a component of the input section. This pen 1
2 is equipped with a pen interface 13, and a pen 12
The pen coordinates are output as data based on the signal input by. Further, the keyboard 10 is provided with a key interface 11, and is converted into data corresponding to the key pressed on the keyboard 10. Further, the handwriting editing interface 16 reads the handwriting recognition dictionary 17 based on the pen coordinates given by the pen interface 13 and outputs the recognition result.

Also, R for storing these various data
An AM 22, a ROM 23 for storing a control program, a print controller 24 for driving the printer 25,
A display controller 15 that drives the display device 14 is provided.

Floppy disk 28, IC card 26
Are provided via the FD controller 29 and the IC card interface 27, respectively, and are controlled by these, and data can be loaded / saved.

The respective units are drive-controlled by the CPU 21. In the word processor having the above configuration, when an operation such as moving or copying is performed on a predetermined area, the designation of the area will be described later based on the pen coordinates input by the pen 12 and given by the pen interface 13. Recognize each case.

That is, the same point as the cursor is recognized by touching with a pen. In this case, it is possible to make two choices, one for recognizing when the pen touches the character input screen and one for recognizing when the pen moves away from the character input screen. In addition, when the start point and the end point of the area to be specified are recognized by drawing an image having a shape for recognizing the area specification with the pen, the time during which the pen is in contact with the character input screen is further predetermined. It may be recognized by judging whether or not it is the set time or more. In the embodiment of the present invention, the constitution can be appropriately selected from these four cases.

Each of the cases will be described below. First, the case where the pen touches the character input screen will be described with reference to the flowchart of FIG. 3 and FIG. 7 showing the operation screen.

When a pen is touched on the character input screen, a pen interrupt occurs and coordinate data is obtained (STEP.
1). Then, the range of the cursor position is obtained in advance by coordinates, it is checked whether the coordinate data of the pen is within that range, and if it is within the range, it is regarded as the cursor position (S
TEP.2). If it is at the cursor position, it is checked whether or not the area can be currently specified (STEP.3). If the area can be specified, the area is specified (STEP.4).

Regarding the area designation, the area can be designated when the area can be designated as in the case of document creation and the functions such as movement, deletion and copying can be used. Therefore, as shown in FIG. 7A, when the cursor position is touched with a pen, as shown in FIG. 7B, the position of the cursor is replaced with the area designation mark, and the start point of the area is designated. it can. In addition, the end point of the area is similarly determined.

Next, a case where the pen is moved away from the character input screen will be described with reference to the flowchart of FIG. 4 and FIG. 8 showing the operation screen. Touch the character input screen with the pen to see if the pen leaves the screen (U
Check P) (STEP.5). The output data of the pen is continuously ignored while the button is pressed. If the pen moves away from the screen, get the current coordinates (STEP.6). Then, as in the above case, it is checked whether the coordinate data of the pen is within the range, and if it is within the range, it is regarded as the cursor position (STEP.
7). If it is at the cursor position, it is checked whether the area can be currently specified (STEP.8). If the area can be specified, the area is specified (STEP.9).

Therefore, as shown in FIGS. 8A and 8B, when the cursor position is touched with the pen and the pen is moved up at the touched position, as shown in FIG. 8C,
The position where the cursor was present is replaced with the area designation mark, and the starting point of the area is recognized.

Next, the case of recognizing the shape drawn by the pen will be described with reference to the flowchart of FIG. 5 and FIG. 9 showing its operation screen. In this case, it is assumed that the gesture function is valid in advance. The fact that the gesture function is effective means that it is possible to perform a function corresponding to each figure by drawing a specific figure on the screen with a pen, such as deleting one character or inserting a space. .

After the pen is touched on the screen, it is checked whether or not the drag is in progress (STEP.11). If dragging is in progress, the generated coordinate data is detected (STEP.18), converted into the format specified in the gesture buffer and stored (STEP.19). At the same time, a line is displayed on the screen as shown in FIG. 9B so that the shape drawn by the pen can be seen (STEP.20). The above steps are repeated during dragging.

When the pen leaves the character input screen (STEP.12)
, Create a buffer for handing over to the recognition side based on the stored coordinate data (STEP.13), and execute recognition (S
TEP.14). In this case, if the shape is not recognizable and the recognition result is an error, error processing such as sounding a buzzer is performed and the process ends (STEP.17). On the other hand, when a corresponding command is obtained from the recognition result, the process shifts to each process by the command. If the command is an area specification (STEP.16),
Currently, check whether it is possible to specify the area (STEP.21),
If possible, specify the area. This operation
As shown in (c), the area is designated (STEP.22).

Finally, a case of recognizing the pen by touching the character input screen will be described with reference to the flowchart of FIG. 6 and FIG. 10 showing the operation screen.

When the character input screen is pressed with a pen (STEP.3
1) As shown in Fig. 10 (b), the cursor moves to the contact position and at the same time the timer is started (STE
P.32). On the other hand, if the pen is being pressed or dragged (STEP.33), the timer is updated (STEP.34). Therefore,
When the pen leaves the character input screen (STEP.35), the timer elapsed time (t) at that time is checked and compared with a predetermined time (u) (STEP.36). This fixed time is generally longer than the time for touching the screen with the pen when the cursor is moved, and is an approximate time that is considered to be intentionally pressed. Where (t) ≧
If it is (u), it is considered that the pen has been pressing on the screen for a certain period of time, and the area designation command is output (STEP.37).
As shown in 0 (c), the area is specified and the timer is reset at the same time (STEP.38). On the other hand, if (t) <(u), it is considered as just a pen input, and only the pen coordinates at that time are output (STEP.39).

The selection of these area designation methods described above is performed by a pen, but a method suitable for each user or each application can be selectively used, and the range of pen operations can be widened. Moreover, since the handwriting feeling can be further enhanced, the operation can be performed easily and quickly.

As described above, according to the word processor of the present invention, the area recognition unit for recognizing the specified area in the document in which the command is executed is configured to detect the specified area based on the screen input information. Both the start and end characters,
The character at the cursor position on the processing screen where the pen is touched, or the character on the processing screen where the image for recognizing the area drawn by the pen is recognized, or the pen is touched for a predetermined time or longer. The selection recognition means for recognizing a character between the characters including the start point and the end point as a designated area while selecting one of the characters on the processing screen is provided for each user, or The method that suits each application can be used properly, and the area can be specified quickly and easily.
