Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device, and more particularly to an information processing device for controlling a display area of a display screen.

[0002]

2. Description of the Related Art Generally, in a document processing apparatus represented by a word processor or the like, a kanji character converted by, for example, kana-kanji conversion or the like is arranged at a cursor position displayed on a display screen. At this time, the cursor position is usually updated sequentially according to the character input.

By the way, there are many demands for correction or insertion of a document after or while the document is created by repeating the above-mentioned operation.

Therefore, it is necessary to move the cursor to the position where the user feels the need. Conventional means used for responding to such a request has been achieved by providing a key for controlling the movement of the cursor (often a key for moving the cursor up, down, left and right) and pressing the key.

[0005]

However, when the cursor is moved to the target position by using such a key for controlling the movement of the cursor, it is necessary to make full use of the cursor control key, which is a serious problem. It was troublesome.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the prior arts described above, and it is intuitively easy to understand, and a desired area on a display screen is designated all at once and the area is designated. The present invention aims to provide an information processing device that can easily confirm the above.

In order to solve this problem, the information processing apparatus of the present invention has the following configuration. That is, position detecting means arranged on the front surface of the display screen for detecting a touched position of the panel, area display means for displaying a predetermined area on the display screen, and form control means for controlling the display form of the predetermined area. When the position detecting means detects that the position of the panel corresponding to the predetermined area is touched, the form control means sets the display form of the predetermined area to the first form. The form is changed to the second form.

[0008]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

<Description of Schematic Configuration of Apparatus (FIG. 1)> FIG. 1 shows a schematic configuration of a document processing apparatus according to the embodiment.

In the figure, reference numeral 1 is a CPU for controlling the entire apparatus, which operates in accordance with a program stored in a program area 2a in the memory 2. In the program area 2a, in addition to the document editing program, programs relating to the flow charts of FIGS. 4 and 11 described later are stored. Further, in the document area 2b in the memory 2, the document information being edited is expanded. Reference numeral 3 is a VRAM, and the image data developed here is 1 of the display device.
It is displayed on the CRT4 which is the one. 5 is a character font RO
M is used when, for example, the character pattern corresponding to the character code in the document area 2b is expanded in the VRAM 3. Reference numeral 6 denotes a transparent pressure-sensitive touch panel located on the front surface of the display screen of the CRT 4, and the position information touched by the operator's fingertip is fetched by the CPU 1. In addition, 7 is a keyboard for inputting various information, and 8 is an external storage device capable of storing a plurality of document information. Reference numeral 9 denotes a speaker, which is used when the touch panel 6 is pressed with a finger and released, and also when acoustically informing various states to the outside.

<Description of Operation at Menu Selection (FIGS. 2 to 4)> In the menu selection in the embodiment, icons indicating various processing contents displayed on the display screen are manually designated. More specifically, it is designated by pressing the surface of the touch panel 6 corresponding to the icon displayed on the CRT 4 with a finger or the like (see FIG. 2).

The processing of the CPU 1 is as follows.

That is, when the operator pushes on the touch panel 6, the CPU 1 reads the coordinate position, inverts the corresponding icon, and informs which icon (menu) has been selected. However, the processing of the menu is not executed unless the finger is once released from the touch panel 6.

There are two reasons for this. First, if the contents of the icon specified by the finger are immediately executed,
This is because, for example, when there is another menu during the execution process, there is a fear that one process will be selected without checking the menu contents. The second is a response when an unintended icon is selected.

Therefore, in the embodiment, when the designation of the icon is confirmed, the finger is released from the touch panel 6. For example, in FIG. 2, even if the operator mistakenly selects "Menu B" despite the intention of selecting "Menu C", the operator can still select "Menu B" without changing the state (while keeping his / her finger on the touch panel). , "Menu C"
Should be selected. At this time, it goes without saying that the icon of "menu B" is normally displayed, and this time, "menu C" is highlighted. Then, the operator confirms that "Menu C" is highlighted and releases the finger from the touch panel 6 so that the process of "Menu C" can be executed. In short, as shown in FIG. 3, it is possible to select another icon from the time α when the touch panel 6 is pressed to the time β when the finger is released.

The above-mentioned processing contents will be described as a processing procedure of the CPU 1 as shown in the flow chart of FIG.

First, in step S1, a menu (icon) group showing various processing contents is displayed on the CRT 4. Next, in step S2, the operation waits until the touch panel 6 is pressed with a finger or the like. When it is detected that the surface of the touch panel 6 has been pressed with a finger or the like, only the corresponding menu is highlighted in the next step S3, and step S3 is executed until the finger is released from the touch panel 6 in the next step S4. That is,
During this time, the menu selection can be changed.
When it is detected in step S4 that the finger has been released from the touch panel 6, processing of the corresponding menu (inverted icon) is executed (step S5).

When an area where no icon is displayed is pressed with a finger, it is determined that no icon is specified.

<Description of cursor control (FIGS. 5 to 11)>
Next, control of the cursor at the time of editing a document in the embodiment will be described.

FIG. 5 shows a display example of a document. Reference numeral 50 in the figure indicates a cursor.

In the embodiment, when the touch panel 6 is pressed with a finger while the document is being edited, that is, while the document is displayed on the CRT 4, the cursor 50 disappears and the display screen corresponding to the position pressed with the finger is displayed. The mark 51 is displayed at the upper position. This state is shown in FIG. The mark 51 is displayed while the surface of the touch panel 6 is being pressed by a finger, and the designated position thereof is linked to the change.
The operator can move the mark 51 to a desired position and then release the finger from the touch panel 6 to display the cursor 50 at that position (see FIG. 7). Thereafter, the operator operates a normal editing process such as insertion and deletion at this cursor position.

As a result, the cursor can be easily and quickly moved to a desired position without using the cursor keys one by one as in the conventional case.

The touch area of the finger on the touch panel 6 is unstable, and when the mark 51 is displayed at the corresponding position on the display screen, the mark 51 is displayed in a staggered manner, which corresponds to the previous position of the mark 51. Touch panel 6
The display position of the mark 51 is not changed unless it is deviated by 16 dots (not necessarily the size of the displayed character) from the reading coordinate of.

Furthermore, when it is determined that the position of the mark 51 is finally determined, the cursor 50 is displayed at the character position closest to the position. At this time, the updated cursor 50 is displayed at least in the adjacent character at the target character position. In order to correct this, the cursor position correction window 61 is displayed as shown in FIG.

In addition to the cursor position correction window 61,
In the embodiment, as shown in FIG. 9 and FIG.
62, the switching is performed by the area 60a in the figure.
The touch panel 6 corresponding to (61a, 62a) is once pressed with a finger and then released to execute. Now, cursor 50
If the position of is corrected, the direction is indicated by 60b to 6b.
The area of 0e can be corrected by executing the above-mentioned operation.

The window 61 is used to display the front, rear, left and right screens for one display screen, and the window 62 is used to move to the beginning or end of the sentence where the cursor is positioned or to move to both ends of the display screen. In the window,
Both operations are executed when the finger is released from the touch panel 6 described above.

To carry out the above principle and its contents, the CPU 1 processes the flow chart shown in FIG. The flowchart will be described below, but it is assumed that a document is already displayed on the display screen at this time.

In step S10, it is determined whether or not the touch panel 6 is pushed with a finger. Based on this judgment, the touch panel 6
When it is detected that is pressed with a finger or the like, the process moves to the next step S11 to erase the cursor 50 at that time,
The mark 51 is displayed at the position on the display screen corresponding to the touch position (step S12).

Next, in step S13, it is determined whether or not the finger is released from the touch panel 6. At this time, if it is determined that the finger is still touched, the touched position is displayed on the currently displayed mark 51. On the other hand, it is determined whether or not the position is more than 16 dots away. If it is determined that the input touch position is within 16 dots with respect to the position of the mark 51, the process returns to step S13 (the mark 51 is immovable), but if not, the process proceeds to step S13.
Moving to 15, the mark 51 is displayed at the position on the display screen corresponding to the input touch position. That is, in steps S13 to S15, the mark 51 can be changed and moved to an arbitrary position.

When it is detected in step S13 that the finger has been released from the touch panel 6, step S16 is performed.
Then, the mark 51 is erased, and instead the cursor 50 is displayed at a character position near the mark position (step S
17). Next, in step S18, the cursor position correction window 60 is displayed at a position away from the position where the cursor 50 is displayed, and in step S19, the window 6 described above is displayed.
After switching to 1, 62 or correcting the cursor position, post-processing is executed.

In the above description of the flow chart,
Although the cursor 50 disappears when the touch panel 6 is pressed with a finger, the original cursor may be deleted and the cursor may be displayed at the updated position when the finger is released. In this case, the process of step S11 is performed in step S1.
It can be achieved by executing before or after step 6.

Regarding the display position of the cursor position correction window 60, if the display position of the cursor 50 is on the right side of the display screen, it can be easily achieved by displaying the window on the left side. That is, it is sufficient if four coordinate positions (upper, lower, left and right positions) with respect to the display position of the cursor 50 are set in advance.

As described above, according to the present embodiment, it is possible to change the cursor position during document editing by touching the touch panel, and it is possible to significantly improve operability. .

The mark 51 in the above embodiment is used.
The movement of is relatively smooth and is easy for the operator to see, but the movement may be performed in units of the size of the displayed character. At this time, when the finger is released from the touch panel 6, the cursor 5 is moved to the position of the mark 51 (the cursor 50 itself may be used).
0 will be displayed.

Further, in the embodiment, the present invention is not limited by the application to the document processing apparatus and the description of the cursor movement when displaying the content of the document. That is, the present invention can be applied as it is to a conventional information processing apparatus that executes various processes by controlling a cursor. For example, when a finger is pressed on the touch panel 6 even when a menu is selected, a mark 51 is displayed on the display screen corresponding to the pressed position, and the mark 51 is 1
When you come over one icon, that icon can be highlighted.

[0036]

As described above, according to the present invention, it is possible to intuitively understand the desired area on the display screen all at once and to easily confirm that the area has been specified.
