Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user interface device capable of expanding a desired position without deteriorating operability, and a recording medium on which a program is recorded.

[0002]

2. Description of the Related Art As shown in FIG.
For example, a computer 101 such as a personal computer has been widely used as a user interface device that displays images and characters on the screen 2 and receives an operation from a user. In these computers 101, to make it easy for the user to operate,
There is a demand for displaying more information, and the resolution of the display 102 is increasing year by year. Further, a computer 101 and a display 102 capable of switching resolutions as needed are also used.

In recent years, the computer 101 employs a GUI (Graphical User Interface) as an interface method with a user so that a beginner can easily use the computer 101. Each application program executed by the application processing unit 113 includes: Display processing unit 11
4 to display icons and characters of an arbitrary size on the screen of the display 102,
3 and processing according to the input from the keyboard 104. The application processing unit 113 can simultaneously execute a plurality of application programs, and the display processing unit 114 can simultaneously display the plurality of application programs on one screen by, for example, displaying a window.

Here, the size of characters and icons displayed by the application program is set in advance by the creator of the application program. In many application programs, the size of icons and characters can be adjusted by the user.

[0005] However, for example, when the resolution assumed by the creator of the application program is different from the actual resolution of the display 102, or the size of the icons and characters is different between a plurality of simultaneously displayed application programs. In the case of being different, there is a possibility that a portion where it is difficult to see details appears on the screen of the display 102.

If the user makes individual settings, the appearance of difficult-to-see portions can be prevented to some extent, but the setting is time-consuming. In addition, since icons and characters whose sizes can be set are often limited, there is a possibility that a part that is difficult to see only by the user's setting may remain.

Further, as described above, the computer 101 and the display 102 capable of switching resolutions.
Then, the resolution can be changed in order to see the details of the portion, but when the resolution is changed, each member on the screen, such as an icon or a character, is rearranged. As a result, if the resolution is changed every time the details are viewed, the operation for changing the resolution is not only complicated, but also the position of the above-mentioned portion on the screen is changed, and it is necessary to search for a desired portion.
Operability is reduced.

Therefore, the computer 1 shown in FIG.
01 is provided with an enlarged display processing unit 121. When the application program for implementing the enlarged display processing unit 121 is executed, the enlarged display processing unit 121 occupies a specific area α in the display screen of the display 102 as shown in FIG. Further, the enlarged display processing unit 121 acquires, from the display processing unit 114, a bitmap image of a location A0 near the mouse pointer P0 operated by the mouse 103, and displays the enlarged bitmap image in the area α.
As a result, a portion where details are difficult to see on the screen is enlarged and displayed in the area α without switching the resolution, and the user can grasp the content of the portion.

[0009]

However, in the above configuration, when the enlargement ratio at the time of enlargement to the area α becomes large, for example, when the difference between the assumed resolution and the actual resolution is large, jaggies (jaggies) of the contours occur. ) Becomes conspicuous, and it becomes difficult to determine the enlarged portion A0. Also,
In the above configuration, since the area α for enlarged display always occupies a part of the display screen, the area for displaying other information is narrowed. As a result, in the above-described conventional configuration, a desired position can be enlarged without changing the resolution, but there is a problem that operability may be reduced.

[0010] The present invention has been made in view of the above problems, and an object of the present invention is to realize a user interface device capable of expanding a desired position without lowering operability.

[0011]

According to a first aspect of the present invention, there is provided a user interface device comprising an enlarged display unit for enlarging and displaying a portion pointed to by a pointing device on a screen. The user interface device includes a control unit that causes the enlarged display unit to display an enlarged display window for enlarging and displaying the portion only while a predetermined specific key is being pressed. And

In the above arrangement, the control means monitors whether or not a particular key is being depressed, and displays the enlarged display window on the enlarged display means only while the key is being depressed. Thus, the user interface device can enlarge and display, for example, a position pointed to by a pointing device such as a mouse, a trackball, or a touch panel in an enlarged display window. Thus, the user of the user interface device can, for example,
If the resolution of the display screen is set high, such as when some characters or figures are displayed small and the details or content are difficult to see, change the resolution by enlarging the characters and figures. You can check the details and contents of characters and figures without having to.

Further, when the depression of the specific key is completed, the control means instructs the enlargement display means to end the display or stops issuing the enlargement display instruction, and displays the enlarged display window. Terminate. Therefore, the user interface device can display the enlarged display window only while a specific key is being pressed, that is, while the user determines that it is necessary, and can stop displaying the enlarged display window while it is unnecessary. . Thus, unlike the related art in which the enlarged display window always occupies a specific area, the area can be diverted to display other information when unnecessary, so that the screen can be used more effectively. As a result,
Since the user of the user interface device can use a wider screen, it is possible to realize an interface device that can enlarge a desired position without deteriorating operability.

According to a second aspect of the present invention, there is provided a user interface device comprising an enlarged display means for enlarging and displaying a portion pointed by a pointing device on a screen. The character display is characterized in that, when a character is included in the portion, the character is displayed in a font having a larger point number. Note that the enlarged display means constructs a database indicating the position of each character displayed on the screen based on a character display instruction to an operation system or the like by each application program, and inquires the database, or By inquiring, for example, an application program that uses the location pointed to by the pointing device as a display area, the characters included in the location pointed to by the pointing device can be specified.

[0015] In this configuration, when the enlarged display means displays a window for enlarged display, if a character to be enlarged is included, the character is displayed in a font having a larger point number. Unlike the conventional technology of enlarging an image, characters can be displayed with a smooth outline even when the enlargement ratio is increased. Therefore, the user of the user interface device enlarges and displays the characters even when some characters are displayed small and the details and contents are difficult to see, for example, when the resolution of the display screen is set high. By changing the resolution,
With smooth contours, you can check details and contents of characters. As a result, it is possible to realize an interface device capable of expanding a desired position without lowering operability.

Further, in the user interface device according to the third aspect of the present invention, in the configuration according to the second aspect of the present invention, the enlarged display means is displayed on the enlarged display means only while a predetermined specific key is being pressed. Is provided with control means for displaying an enlarged display window for enlarging the image.

In this configuration, similar to the first aspect, the enlarged display window is displayed only when it is necessary, and is not displayed when it is not required, so that a wider screen can be provided to the user.

According to a fourth aspect of the present invention, in the configuration of the first or third aspect of the present invention, the control means includes: an enlargement mode for receiving depression of the specific key; It is possible to switch between a standby mode in which the window for enlarged display is not displayed even if is pressed.

According to this configuration, when the mode is switched to the standby mode, the enlarged display means does not display the enlarged display window even when a specific key is pressed. Therefore, when an application program that uses the key for another purpose is used, or when all characters and graphics are displayed sufficiently large, the enlargement display window is displayed. Can be suppressed.

Incidentally, the user interface device may be realized only by hardware, or may be realized by a computer executing a program. Specifically, the recording medium according to the fifth aspect of the present invention is a recording medium, comprising: a magnifying display unit that magnifies and displays a position pointed by a pointing device on a magnifying display window on a screen; A program for operating a computer is recorded as control means for displaying the window for enlarged display on the enlarged display means only while is pressed.

Further, a recording medium according to the invention of claim 6 is:
In the case where a character is included in a position pointed to by the pointing device on the screen, a program for operating a computer is recorded as enlarged display means for displaying the character with a larger number of points. I have.

When a program is read from these recording media and executed by a computer, the computer operates as a user interface device according to the first or third aspect. Therefore, similarly to the first or third aspect, it is possible to realize an interface device capable of expanding a desired position without lowering operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention.
The following is a description based on FIG. 9. That is, as shown in FIG. 1, the user interface device according to the present embodiment uses a GUI (Graphical User Interface) as an interface method with a user, such as a computer employing Windows (registered trademark) as an operating system (OS). The computer 1 employs a mouse and a mouse (pointing device) 3 on a display screen of a display 2 to display a graphic or character string indicating an operation target or an operation and a mouse pointer. You can move with. Further, an operation target and an operation can be specified based on an operation on the mouse 3 such as a point operation, a click operation, a double-click operation, a drag operation, and a drag-and-drop operation. This realizes a computer that is easy for even a novice user to operate as compared with a computer that employs a character-based user interface (CUI) that operates by inputting a command character string.

Further, on the screen, figures and character strings that do not accept mouse operation can be displayed. By arranging these near the figures and character strings that accept mouse operation, it is possible to explain what can be operated by mouse. . Computer 1
Is also connected to the keyboard 4 and the computer 1
Can accept operations by keys on the keyboard 4 such as character input and cursor movement instructions.

More specifically, the computer 1 includes a mouse input processing unit 11 for receiving an input from the mouse 3 and a key input processing unit 12 for receiving an input from the keyboard 4.
In response to an instruction from the application processing unit 13 that executes the application program and the mouse input processing unit 11, the mouse pointer is moved, and the application program is displayed in the area allocated to each application program on the display screen of the display 2. Display processing unit 1 that displays figures and character strings specified by
4 is provided.

Each of the processing units 11 to 11 described above and below will be described.
22 (23) indicates that the arithmetic means such as a CPU is a ROM or R
Execute a program stored in storage means such as AM,
This is a functional block realized by controlling peripheral circuits such as an interface circuit as necessary. Therefore, a computer having these means can store the program on a recording medium (eg, a CD-ROM).
The computer 1 according to the present embodiment can be realized only by reading the program and executing the program. In addition, if a program for downloading a program via a communication path is installed in the computer in advance, the program can be distributed to the computer via the communication path. Further, the program may be an application program indicating the procedure of the entire process, or a basic program (for example, an OS or a library) capable of executing a part or all of the process by being called in a predetermined procedure. If already exists,
A part or all of the above processing may be replaced with a code or a pointer for instructing the arithmetic means to call the basic program.

The application program processed by the application processing unit 13 is, for example, a file manager that manages files, or a program such as an application program for document processing, spreadsheets, or control, and is determined when the program is created. With the size and font, or the size and font set by the user, input to both input processing units 11 and 12,
A character string based on the calculation result or a predetermined character string can be displayed. Further, the application program may be a program that can display an operation target or the operation itself as an icon with a size determined at the time of creating the program or a size set by a user. Further, the program may be a program that displays the operation target and the operation itself in a menu format, and that can display a character string indicating each item to be displayed on the menu in a size or font set at the time of creating the program or by the user.

In any case, the computer 1 according to the present embodiment employs a GUI-based user interface, and the display processing unit 14 displays on the display 2 a figure or a graphic of an arbitrary size and shape. Can display characters. Therefore, the above application program:
For example, a combination of a character, a size and a font, a combination of data indicating an image and a size, and the like are displayed on the display processing unit 1.
For example, characters or images having a size according to the preference of the program creator or the user can be displayed by designating to 4 or the like.

Further, the computer 1 according to the present embodiment
A magnifying display processing unit (magnifying display means) 21 for magnifying and displaying a location indicated by the mouse pointer in a magnifying display window only while a key (pop-up key) predetermined by the user is pressed; A mode processing unit 22 for switching the mode of the enlarged display processing unit 21 in response to a mouse operation. Note that the mode processing unit 22 and the above-described key input processing unit 12 correspond to control means described in the claims.

The enlarged display processing unit 21 according to the present embodiment
As shown in FIG. 2, there is a standby mode in which an enlarged display window is not displayed regardless of a key operation, and an image enlargement mode in which a portion indicated by a mouse pointer is enlarged as a bitmap image, as will be described in detail later. In addition, a character enlargement mode is provided in which a character included in a portion indicated by a mouse pointer is extracted and the character is displayed in a font having a larger point number instead of being enlarged as a bitmap image.

In this embodiment, a combination of a key operation and a mouse operation is selected as an example of an operation for mode transition, and the mode processing unit 22 double-clicks the key Ka (in the figure, MWC). When the mouse input processing unit 11 and the key input processing unit 12 receive the combination, the instruction can be directed to the enlarged display processing unit 21 to shift from another mode to the image enlargement mode.
Further, when accepting key Kb and double-click, mode processing unit 22 instructs transition to character enlargement mode, and transitions to standby mode by a combination of key Kc and double-click. The mode processing unit 22 according to the present embodiment allows a user to preset the mode transition keys Ka to Kc.

The operation of the computer 1 having the above configuration will be described below with reference to FIGS. That is, when an application program realizing the enlarged display processing unit 21 and the mode processing unit 22 is started, the mode of the enlarged display processing unit 21 is set to the standby mode, as shown in FIG. In this state, regardless of whether or not the pop-up key is pressed, the enlarged display processing unit 21 performs, for example, the standby process of step 1 (hereinafter, abbreviated as S1) as shown in FIG. It waits until the mode is switched, such as by repeatedly executing it.

For example, a predetermined operation for shifting to the image enlargement mode, such as a combination of a pressing operation of a mode transition key Ka and a double-click operation, is performed by the mouse input processing unit 11 and the key input processing unit 12. When accepted, the mode processing unit 22 instructs the enlarged display processing unit 21 to shift to the image enlargement mode. In this mode,
In S12 shown in FIG. 4, the enlarged display processing unit 21 keeps pressing down the pop-up key (in S11,
(During YES), for example, by inquiring the display processing unit 14 of an image near the position of the mouse pointer, obtains a bitmap image indicating the location specified by the mouse pointer, and enlarges the image as a bitmap image. I do. Further, in S13, the enlarged display processing unit 21 displays the enlarged bitmap image as a popup window (enlarged display window) W1 by instructing the display processing unit 14 to display a window. Thereby, as shown in FIG. 5, a pop-up window W1 is displayed on the screen of the display 2, and the position A1 indicated by the mouse pointer P1 is displayed in the pop-up window W1.
An image obtained by enlarging the image displayed in is displayed. In addition,
The location A1 indicated by the mouse pointer P1 is, for example, the position of the mouse pointer P1 such as a rectangular area surrounded by the coordinates of 20 dots to the left and 20 dots to the left and the coordinates of 100 dots to the right and 20 dots to the right. May be an area defined by relative coordinates with respect to, or a predetermined unit such as an icon, a character string, or a menu item indicated by the mouse pointer P1. Further, it may be a range or an icon selected by a drag operation of the mouse 3.

The processes in S11 to S13 are repeated while the key input processing unit 12 detects the depression of the pop-up key (while YES in S11). When the depression is completed (NO in S11), Enlarged display processing unit 21
Sets the pop-up window W1 to non-display by, for example, instructing the display processing unit 14 to hide the pop-up window W1 in S14, and thereafter sets the pop-up window W1 until the pop-up key is pressed again. Do not display. Therefore,
After the press-down of the pop-up key is completed, the pop-up window W1 is not displayed as shown in FIG. 6, and the display area of the pop-up window W1 includes, for example, a table T displayed by a spreadsheet application program. Other information is displayed.

As described above, in the image display mode, the enlargement display processing unit 21 displays the pop-up window W1 for enlarging and displaying the location indicated by the mouse pointer P1 only while the pop-up key is being pressed down, and presses down. Is stopped, the display of the pop-up window W1 is stopped. Therefore, unlike the related art (see FIG. 11) in which the predetermined screen area α is always occupied and the position A0 indicated by the mouse pointer P0 is continuously enlarged and displayed (see FIG. 11), the area for the enlarged display (α Or, W1) can be diverted to the display of other information, so that the display screen of the display 2 can be used more effectively.

Further, in the state of the standby mode or the image enlargement mode shown in FIG. 2, for example, a combination of the pressing operation of the mode transition key Kb and the double click operation is predetermined for the transition to the character enlargement mode. When the input operation is received by the mouse input processing unit 11 and the key input processing unit 12, the mode processing unit 22 instructs the enlarged display processing unit 21 to shift to the character enlarged mode. In this mode, the enlarged display processing unit 21 performs, as shown in FIG.
By performing substantially the same processing as S11 to S14 shown in FIG. 4, the pop-up window W1 is displayed only while the pop-up key is being pressed. However, in the character enlargement mode, the process of S21 is performed instead of S12, and in S21, the enlarged display processing unit 21 includes the character at the location A2 (see FIG. 8) indicated by the mouse pointer P2 in S21. When the character is enlarged, the character is enlarged by replacing it with a larger number of points than the number of points used for displaying the character at the location A2. As described above, the enlarged display processing unit 21
Since the character font size of the character included in the portion A2 is displayed in a larger size, the pop-up window W2 includes
Characters with smooth outlines are displayed regardless of the enlargement ratio.

More specifically, in S21, the enlarged display processing unit 21 receives the current position of the mouse pointer P2 (for example, XY coordinates) from the mouse input processing unit 11, and displays the position. Identify the application program that is running. Further, the enlarged display processing unit 21 inquires of the application program about the character displayed at the location A2 indicated by the mouse pointer P2. Note that the enlarged display processing unit 21 may inquire, as the location A2, a coordinate range such as a coordinate range relatively determined from the position of the mouse pointer P2 or a coordinate range specified by a drag operation of the mouse pointer P2. For example, if only the position is inquired and, for example, in the case of a menu display, the determination of the position A2 may be left to the application program, such as setting the entire item to the position A2.

In any case, when the character code, the font, and the point number of the character included in the point A2 are returned from the application program, the enlarged display processing unit 21 determines the point number in advance. Is replaced by the number of points having the predetermined size or the number of points having a predetermined magnification. As a result, the enlarged display processing unit 21 displays, in the popup window W2, a character having the same character code and font as the character displayed at the location A2 but different only in the size at the position where the character is to be enlarged and displayed. it can.

Here, the display processing unit 14 can mix characters of different sizes (points), for example, by preparing outline fonts or preparing a plurality of bitmap fonts having different numbers of points in advance. It is configured as follows. Therefore, as shown in FIG. 8, the enlarged display processing unit 21 can enlarge and display a character with a smooth outline, unlike the related art (see FIG. 11) in which the character is also enlarged as a bitmap image.

In the above description, the configuration is described in which the enlarged display processing unit 21 inquires the application program to obtain the character displayed at the location indicated by the mouse pointer, but the present invention is not limited to this. For example,
As in the computer 1a shown in FIG. 9, a screen database 23 that responds to an inquiry from the enlarged display processing unit 21 may be provided instead of each application program.

In this case, the screen database 23 monitors, for example, a character display instruction from the application processing unit 13 to the display processing unit 14, an operation when the display processing unit 14 arranges characters on the screen, and a work area. For each character displayed on the screen, refer to
Detect the font, number of points and position. Further, the screen database 23 stores, for example, a combination of a position, a character code, a font, and the number of points for each detected character. The character code, the font, and the number of points for the characters included in the location indicated by are stored so that they can be answered.

In this configuration, unlike the computer 1 which inquires of the application program itself for displaying characters, since the characters displayed by each application program are managed outside the application program, the processing of the screen database 23 becomes complicated, There is no need to change the application program executed by the processing unit 13. Therefore, when it is time-consuming to change the application program, for example, when using an application program having no source code, the configuration of the computer 1a is more preferable. On the other hand, if the application program can be easily changed, such as when there is a source code or when the application program can be easily switched to a new application program, the configuration of the computer 1 is more preferable. In any case, the same effect can be obtained if the enlarged display processing unit 21 can acquire the character included in the location indicated by the mouse pointer.

In this embodiment, in addition to the character code of the character included in the location A2 indicated by the mouse pointer P2, the number of points and the font are returned by the application processing unit 13 or the screen database 23.
It is not limited to this. For example, if the number of points for enlarged display and the font are previously set in the enlarged display processing unit 21 in accordance with a user's instruction or the like, characters may be displayed with the settings. However, if the font is also answered, the above point A2
Since it can be enlarged and displayed in the same font, it can be displayed more easily. If the number of points is also replied, if characters having different numbers of points are mixed in the location A2, the characters can be enlarged while maintaining the ratio of the size of the characters, so that the characters can be displayed more easily.

In this embodiment, the user interface device adopting the GUI system has been described.
Even with a CUI user interface device,
This is a case where the application program can display an image of an arbitrary size, and if an enlargement point can be specified, the computer 1 or the computer is configured by selecting on / off of a pop-up key to display / hide an enlarged display window. As in 1a, an effect that a wider screen can be used is obtained. Further, even in a CUI type user interface device, characters of different sizes can be mixed on the display 2 and if the enlarged portion can be designated, the characters included in the enlarged portion are replaced with characters having a larger point number. The effect of displaying characters that are smooth and easy to read, as in the case of the computer 1 or the computer 1a, can be obtained. Where G
In the case of a UI-based user interface device, an application program often displays an operation target or an operation itself with an icon together with a character for explaining the operation target. Can often be set. Therefore, depending on the resolution, there is a high possibility that a portion that is difficult to see is generated. Therefore, applying the configuration of the present invention is particularly effective.
