Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] In a multi-window system, a logical screen and a physical screen do not have a one-to-one correspondence, and an absolute coordinate input device cannot be used. The present invention stores control information corresponding to an application program, converts data from an absolute coordinate input device with the control information, and displays a cursor movement. According to the present invention, absolute coordinate input is performed in a multi-window system. Enables a cursor display controller that can use the device.

[Industrial application field]

The present invention relates to a cursor display device, and more particularly to an input data control device for controlling cursor movement by an absolute coordinate input device.

[Conventional technology]

With the development of personal computers, various processes have become possible. In these various processes, the screen displayed to the operator and the memory in which the application program writes the display data have a one-to-one correspondence. That is, as shown in FIG. 14, the data output by the application program AP was always displayed on the display DSP.

Further, in the case of having a device for inputting data or image information using a tablet or the like, as shown in FIG. 15, the specific area A1 of the entire input area of the tablet DT is assigned to the display area of the display DSP, and the tablet The application program was made so that the remaining areas could be allocated to areas for inputting items, for example. Further, even in an area that cannot be displayed on the screen, an application program has been created so that so-called digitizing input for tracing a large drawing such as a map can be performed. That is, the absolute coordinate data obtained from an absolute coordinate input device such as a tablet is configured to be used effectively, and even if the input absolute coordinate data is outside the display screen, the data is used as graphic information or item input information. Was used as. This is possible because absolute coordinates can be input from the coordinate input device.

On the other hand, in a system in which various processes are simultaneously performed as shown in FIG. 16, in order to clarify the execution of the processes, for example, a memory in which a plurality of application programs write display data and a memory in which a display DSP displays are specified. A multi-window method has been widely used in which a memory is separately provided and a part of a memory for storing display data in an application program is divided and displayed.
(In general, the image information of the memory in which the application program writes the display data is called the logical screen, and the image displayed by the display DSP is called the physical screen.) In other words, in the multi-window method, a plurality of images are displayed. A part of the logical screen of is displayed by being allocated to the physical screen.

Also in this multi-window method, a method using a cursor instruction is often used, and a relative coordinate input device such as a mouse is often used as the cursor moving means.

[Problems to be solved by the invention]

Since a relative coordinate input device such as a mouse is used in the above-mentioned multi-window method, in the control processing for obtaining and displaying the cursor coordinates, the cursor is always controlled so as to be included in the display image. In a system having such control processing, that is, in a multi-window system, in an application program configured to use a so-called tablet or the like for inputting absolute coordinates as described above, the function of the application program deteriorates. It had a problem of being lost. For example, there are cases where data outside the screen cannot be entered or items cannot be entered. Further, in the multi-window method, the position of the logical screen to be cut out and displayed and the position of the physical screen to be displayed do not have a one-to-one correspondence and can be freely changed by an operator's instruction. Therefore, in a multi-window system, an application program that requires absolute coordinates has a problem that it cannot be used, that is, cannot be executed because the effect is reduced and the coordinates are converted.

In view of the above conventional drawbacks, the present invention provides an application program in a multi-window system and an application program requiring absolute coordinates without deteriorating the use effect of the application program requiring absolute coordinates even in a multi-window system. It is an object of the present invention to provide an input data control device that can be mixedly executed.

[Means for solving problems]

 FIG. 1 is a functional block diagram of the present invention.

Reference numeral 1 is a coordinate input means for inputting absolute coordinates, 2 is a definition register group for storing a plurality of control information for converting the input data of the coordinate input means 1 into necessary data, and 3 is stored in the definition register group 2. Designating means for designating at least one of the plurality of control information to be controlled is control means for converting the coordinate data added by the coordinate input means into the required data.

[Action]

In accordance with an instruction from an operator or the like, data designating control information to convert input data input from the coordinate input means 1 into required data is added to the designating means 3, and the designating means 3 is stored in the definition register group 2. The data indicating at least one of the control information is output to the control means 4. The control means 4 reads a plurality of control information stored in the definition register group 2 from the data added by the designating means 3, and uses the control information to convert the absolute coordinate data added by the coordinate input means into necessary data. To do. The control information is, for example, information for converting into data required in the display coordinate area of the display device or information for making the operation of the control means 4 non-conversion, and by this information necessary data for various devices can be obtained. Can occur.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to the drawings.

(Operation) FIG. 2 is a processor block diagram of an embodiment of the present invention. The processor (CPU) 5 is, for example, a microprocessor and has a bus line 6. A display 7, a keyboard 8, a tablet 9, a memory 10 and a hard disk device 11 are connected to the bus line 6.

When the processor (CPU) 5 is operated by turning on the power, it is stored in a read-only memory (not shown).
The IPL program is executed to read the OS (operating system) program stored in the hard disk device 11 and store it in the OS area M1 in the memory 10. Then, the OS program stored in the OS area M1 is executed.

The OS program has a multi-window display function, and as will be described later, when an application program execution request is input from the keyboard 8 or the tablet 9 by an operator's operation, the application program stored in the hard disk device 11 is executed. memory
Stored in application program area M2 in 10.
Then, the application program is executed under the control of the OS program. As a matter of course, the application program performs the processing corresponding to the input data with respect to the input from the keyboard 8 and the tablet 9, and the display 7
It is a program that outputs the processing result to.

In the embodiment of the present invention, interrupt management is performed by the OS program, and task management of the program to be executed is performed.

FIG. 3 is a basic operation flowchart of the OS program. When coordinate data is input from an input device such as the tablet 9, an interrupt IRQ is generated from the input / output circuit (not shown in FIG. 2) provided between the tablet 9 and the bus line 6 to the processor (CPU) 5. To do. The OS program has an interrupt processing program for an input / output interrupt in advance, and the processor (CPU) 5 executes ST1 of this interrupt processing program. The interrupt processing program ST1 performs, for example, a process of reading data in response to an input device interrupt and a process of temporarily storing the read data in an area (work area or the like in the memory 10) M3 instructed in the OS program. Then, the interrupt processing program ends the execution. This end is
All are managed by the OS program, and the OS program performs processes ST2 to ST4 for detecting a program to execute a process that should respond to the input data in advance. That is, the program to be executed is detected by the queue of input events. Then, the process to respond to the target input data is executed ST5.

In FIG. 3, a process of responding to data from the tablet 9 is performed. For example, in the case of logical screen control, data input from the tablet 9 (at this time, the data already stored in the memory 10 by the process ST1) is displayed on the physical screen. The position where the cursor is pointed within is detected, and the process for pointing the cursor, that is, echo back is performed. The processing so far is only a response to the addition of input data, and the processing (application program) intended by the operator is not executed using this input data. The OS program also manages these, and performs the detection processing ST6 to ST8 by the queue in the same manner as the response to the data input described above, and detects and executes the application program APX to be executed. The interrupt IRQ in the input circuit is the application program APX
Is executed as a result of adding the request to the OS program when an input request is generated, and the application program detected by the queue is in the wait state at this time and is re-executed by the OS program. Then, the application program APX processes the input coordinate data. For example, if the information displayed by the application program is an item input, the designated item is processed. If the program is an input program for figures, etc., the processing for fetching the figure input data and storing it in the memory or the like is performed.

FIG. 4 (a) is a flowchart of tablet processing, and FIG.
FIG. 4B is a register configuration diagram, and FIG. 4C is a key input processing flowchart.

The tablet input process is a detailed flowchart of the logical screen control process ST5 in FIG. 3 described above. An interrupt process is executed by an input interrupt of the input data from the tablet 9, and this process is executed after capturing the data.
In the embodiment of the present invention, there are a plurality of processes for the input data of the tablet 9, and there are one system mode and a plurality of application modes (application modes). When the tablet input process starts to be executed, first, a process ST10 for determining whether the process for this input is the system mode or the application mode is performed. In the embodiment of the present invention, the memory 10 has a definition register area M5, and the above-mentioned discrimination processing ST10 is performed according to the data stored in the mode register (FIG. 4 (b)) MMO in this definition register area. Makes a distinction.

FIG. 4 (c) is a flow chart of the process of storing the mode designation data in the mode register MMO. In the embodiment of the present invention, the mode is designated by the key, which is registered in the OS program like the above-mentioned logical screen control process ST5, and an interrupt is generated by the operation of the key of the keyboard 8, and the interrupt After the key input interrupt process is performed, the key input process is executed in the queue. When the key input process is executed, first, a process ST20 for determining whether or not the data is data when the mode designation key is pressed. When it is not the data of the mode designation key, another key input data processing ST21 is performed. Other key input data processing
ST21 is data for control information in the OS program and input data in other application programs, and is the corresponding processing. On the other hand, if it is the mode designation key (Y), it is then determined whether the mode designation key is the application mode or the data of each key of the system mode (ST22). When it is the data of the system mode key, a process ST23 of storing "0" in the mode register MMO in FIG. 4B is performed. When the data is the application mode key data, after performing the processing ST24 of storing "1" in the mode register MMO,
Perform processing ST25 that specifies which of the plurality of application-defined registers RA1 to RAn is to be used. Each processing ST21, ST23,
The end of ST25 means that the response process for the input data is completed, and the key input process is completed. By this processing, for example, when the mode designation key is pressed, the data content of the mode register MMO is changed.

Returning to FIG. 4 (a), description will be made. When the mode register MMO is not "1" in the determination ST10 (N), since the system mode is specified, it is input based on the control information stored in the system definition register RS in FIG. 4 (b). Perform data processing ST11. The system mode is a mode in which the physical screen and the logical screen in each application program are related and managed in units of windows that have been determined in advance by the OS program or windows moved by the operation of the operator. Note that this mode is similar to the conventional multi-window management with a mouse cursor.

Further, in the determination processing ST10, when the content of the mode register MMO is "1" (Y), the application mode is specified, so the application definition register specified in the application definition register specification processing ST25 described above is used. Input data processing ST12. In this processing, for example, the cursor is processed outside the physical screen. That is, when an application program for inputting a screen such as a map is being executed, the cursor is displayed in this mode. After finishing the application mode process ST12 and the system mode process ST11, the cursor echo process ST that should display the cursor at the cursor position designated by these processes
13 is performed and this tablet input processing is ended.

The tablet input process is just a response process to the input from the tablet 9, and as described above, after this process, the process in the application program using the input data is executed.

FIG. 5 is a diagram for explaining the operation concept of the present invention. The OS program has a logical screen management unit KLK, a tablet operation mode management unit TOK, a cursor echo control unit KEC, and a tablet driver TDR. In addition, the OS program has a control unit of each input device, task management, and the like, and these various management units manage input / output management, task execution, and application program execution.

The logical screen management unit KLK has logical screens GA, GB, GC corresponding to at least one application program (applications XA, XB, XC) to be executed, and manages the logical screens.

The tablet operation mode management unit TOK associates the absolute coordinate data from the tablet 9 with the logical screen, that is, converts the input data into position data on the logical screen and converts the position data corresponding to the physical screen for displaying the cursor. Manage conversions. The tablet operation mode management unit TOK is a system correspondence definition structure CRS for managing the correspondence described above.
It has application-defined definitions CRA, CRB, and CRC. The system correspondence definition program CRS manages input data using the system definition register RS, and also delivers data to the program that uses the basic input / output I / O etc. supported by the system and the position where the cursor is displayed. For example, a menu input of a system-compatible application program can be performed by pointing the display screen with a cursor. The application-corresponding definition bodies CRA, CRB, CRC pass data to the application program (applications XA, XB, XC) and display a cursor. Each application definition body CRA, CRB, CRC is an application definition register. It corresponds to. In FIG. 5, the application corresponding definition programs CRA, CRB, CRC are added to the application programs XA, XB, XC.
, But the application program may input input data via the system corresponding definition structure, and in this case, the application corresponding definition structure corresponding to this application program is not necessary.

The tablet driver takes in the data in response to the interrupt from the tablet 9. That is, tablet 9
Data is added to the response unit when an interrupt occurs, and the data is delivered to the response unit described above. The tablet operation mode management unit described above performs the process of the flowchart of FIG. 4 (a). Further, the tablet operation mode management unit TOK generates display position data for displaying the cursor at the display position corresponding to each application program by the cursor echo as described above, and the generated data causes the cursor echo control unit KEC to display the display. Write the cursor on the physical screen that should be displayed with. The thick lines in FIG. 5 represent the respective currently active states, and the logical screen corresponding area YA of the tablet corresponds to the area GA1 in the logical screen GA.
Then, the area GA2 in the logical screen is displayed in the window WA displayed on the display. On the other hand, for example, when the application program XC is a program that uses absolute coordinates as input data, even if the specific area in the logical screen is displayed in the window WC after the application program XC is activated, the tablet 9
The tablet operation mode management unit TOK controls so that the data added from is not converted as it is and is added to the application program, and also controls the cursor coordinates in the window area GC2 in the logical screen GC, and the coordinates are passed through the cursor echo control unit KEC. Is displayed on the display 7.

To summarize the above operations, when data is generated from the tablet 9, the processor 5 is interrupted, and the tablet driver TDR operates by the interrupt to transfer the data to the tablet operation mode management unit TOK in the DS program.
Hand over to. Then, the tablet operation mode management unit obtains the position coordinate of the cursor on the logical screen and the position coordinate of the cursor on the physical screen by the application correspondence definition structure corresponding to the application program requesting the input from the tablet 9, and displays the position coordinate. The coordinates of the cursor to be output are output to the display 7 via the cursor echo control unit KEC. Further, the position coordinates corresponding to the logical screen are output to the application program. For example, when the application program XA is a program for inputting a map or the like using the tablet 9 area, the tablet operation mode management unit TOK
The data passed from will be absolute coordinates. However, in the physical screen that is multi-windowed by the OS program, the area GA2 in the corresponding logical screen GA
Display position coordinates are added to the cursor echo control unit so that the cursor is displayed only when the cursor is present inside, and the cursor is displayed in the window WA in the display.

On the other hand, if the application program is a program using relative coordinates, the tablet operation mode management unit JO
K performs a relative cursor operation by the system correspondence definition program CRS, and if the cursor exists in the window displayed on the display, it adds the coordinates of the logical screen corresponding to the position in the window to the application program.

With the above operation, when using the multi-window, an application program that can be input by the conventional relative coordinate input device even if the window is moved and an application program that inputs the absolute coordinates in the input of the drawing etc. It can be operated under a program.

(Definition body and coordinate conversion logic) FIG. 6 is a flowchart of mode switching. In FIG. 4 (c), the mode register MMO for key input
Settings ST24, ST23 and application definition register specification processing ST25
FIG. 6 shows another embodiment for making these settings. In FIG. 4 (c), the mode "0" setting key and the mode "1" setting key are provided separately, but in the embodiment of FIG. 6, the mode change key is used. Is provided and when the key is pressed, the mode is switched to the mode "1" when the mode is "0" and to the mode "0" when the mode is "1". That is, by sequentially pressing the mode change keys, the mode changes to alternate.

When the flowchart of FIG. 6 is started by an interrupt or the like, a process ST50 for extracting one event from the input key, that is, a process for selecting a process to be executed thereafter is executed, and the selection process (at this time, (Processing for key input) is performed to first determine ST51 whether the input key data is a mode switching instruction. When it is not the mode designation instruction (N), other processing is performed. When the mode designation is instructed (Y), next, a discrimination process ST52 of the current mode is performed. That is, the mode register MMO is "1".
Or "0" is determined.

When the mode register MMO is "0", first the process ST53 is performed in which the application definition definition chained to the window control table pointed to by the active window register is the current definition structure, and then "1" is set to the mode register MMO. The process ST54 of storing is performed. These processes ST53, ST
The process of changing the state “0” to the state “1” is terminated by 54.

FIG. 7 is an explanatory diagram of the register and the definition object in the state "1" in the definition register area M5 in the state of the embodiment of the present invention. In addition to the system definition register RS, application definition registers RA1 to RAn, and mode register MMO described above, in the embodiment of the present invention, the current definition register CTR, active window register AWR, system screen definition body WST, window control tables WCT1 to WCTn. Furthermore, each definition STT, AT
It has T1 to ATTn.

The current definition program register CTR is a register for instructing the definition programs STT, ATT1 to ATTn that are currently active.
It is referred to by the application mode process ST12 and the system mode process ST11 in FIG. FIG. 7 shows the case of the application mode, that is, the state 1, in which the application corresponding definition object ATTn is designated by the current definition register CTR. The active window register is a register that indicates the currently active window.

On the other hand, the system definition register RS and the application definition registers RA1 to RAn point to the system screen definition body WST and the window control tables WCT1 to WCTn, respectively, and each definition body is further designated from these tables. The system screen definition body WST and the window control tables WCT1 to WCTn have information for controlling various windows, and each definition body STT, ATT1 to ATTn is one piece of information instructed by the control information.

The position data added from the tablet is converted into target data by the information of these definition bodies STT and ATT1 to STTn.

FIG. 8 is a diagram for explaining the relationship between the application correspondence definition program and the screen. Information B1 is tablet coordinate space Indicate the specific area TR1 inside, X ₁ and Y ₁ are the coordinates of the upper left corner of the specific area, and X ₂ −X ₁ and Y ₂ −Y ₁ are the lengths of the vertical and horizontal sides. (X ₂ and Y ₂ are the coordinates of the lower right corner of the specific area TR1).
Information B2 is a logical screen The coordinates of the upper left corner of the specific area TR2 in the inside are x ₂ −x ₁ , y ₂ −y ₁ represent the length of the vertical side and the horizontal side (x ₂ , y ₂ are the specific area TR 2
Bottom right corner coordinates). Areas TR1 and TR2 designated by these pieces of information B1 and B2 respectively correspond.

Further, the information B3 indicates the specific area TR3 of the logical screen, and a ₁ and b ₁ are the coordinates of the upper left corner of the specific area TR3, a ₂ −a ₁ and b ₂
-B ₁ represents the length of the longitudinal sides and transverse sides (a _2, b ₂ are the coordinates of the lower right corner of the specific region TR3). Information B4 is physical screen Indicate the specific area TR4 inside, and α ₁ and β ₂ are the specific areas T
R4 coordinates of the upper left corner of _{the, α 2 -α 1, β 2} -β 1 represents the length of the longitudinal sides and transverse sides (α _2, β ₂ is the coordinates of the lower right corner of the specific region TR4) . Then, the area T indicated by the information B3, B4
R3 and TR4 correspond respectively.

When using the application-supporting definition program, a specific area TR1 in the tablet coordinate space is designated by information B1, and this area is information B.
It corresponds to the specific area of the logical screen indicated by 2. For example, by setting the specific area TR1 to the entire area of the tablet coordinate space and the specific area TR2 to the entire area of the logical screen, the cursor is not displayed outside the window of the physical screen, but graphic data such as a map is displayed. You can enter. By the above-described operation, the tablet coordinates in the application definition body ATTn are associated with the logical screen and the logical screen and the physical screen. The table TBLB is the most basic corresponding coordinates defined by the user.
Although it is possible to perform coordinate conversion using LB, in the embodiment of the present invention, in order to speed up coordinate conversion, this table is converted to create an application corresponding definition structure.

If the coordinate data X, Y added from the tablet in the above-mentioned conversion from tablet coordinates to logical coordinates, the logical coordinates (x, y) are Required by. Corresponding to the input data X, Y, when displaying a cursor or the like on the physical screen, that is, the display screen, the coordinate data to be displayed on the physical screen, that is, the cursor echo position (α, β) Required by.

Tablet coordinates (X, Y) when application definition is used
Since the logical coordinates (x, y) are obtained from the position coordinates and the position coordinates (α, β) on the physical screen are obtained from the logical coordinates, the tablet coordinate space and the logical screen can be directly related.

Returning to FIG. 6, the explanation will be continued.

In the current mode discrimination processing ST52, the mode register MM
When it is determined that O is “1”, after performing the processing ST55 in which the system definition program chained to the system screen definition program pointed to by the system definition register is the current definition program, the mode register MMO is set to “0”. Process S to store
Do T56. As a result, the process of changing the state "1" to the state "0" is completed.

FIG. 9 is an explanatory diagram of registers and definition bodies. In this state, the current definition register CTR points to the system correspondence definition body, and the processing in the tablet operation mode management unit, that is, the tablet input processing, performs data conversion using this system correspondence definition body. When the definition structure corresponding to the application is used, that is, when the state is "1", the tablet coordinate space and the physical screen correspond via the logical screen. However, when the system correspondence definition body is used, that is, in the state "0", the tablet coordinate space and the logical screen correspond to each other via the physical screen.

FIG. 10 is a diagram for explaining the relationship between the system correspondence definition structure and the logical screen.

The system correspondence definition structure has four pieces of information B5, B6, B7, B8,
The information B5 indicates a specific area TR5 in the tablet space, and this specific area TR5 corresponds to the entire physical screen. First
In FIG. 0, the information B6 represents the entire area of the physical screen. And the information B7 represents the specific area TR6 of the physical screen,
Information B8 represents a specific area TR7 of the logical screen. The coordinate data (X, Y) of the input tablet is different from the case of mode "1". First, from the information B5, B6, the cursor position on the physical screen, that is, the cursor echo position (α,
β). That is, Is converted by. The cursor is displayed with the values of α and β. Then, for example, it is converted into logical coordinates (x, y) required by a system program or the like. This logical coordinate (x, y) is Required by.

This value adds the coordinates requested by the OS program or the cursor coordinates in the logical screen to the program executed under the control of the OS program.

Even in the case of the state "0", the table TBLS having the most basic correspondence is not directly used, and the information B5, B7, B8 is converted in the same way as the application definition body in order to speed up the processing.
The tablet operation management mode is used as the system correspondence definition program.

To summarize the above, when the state “1”, that is, the mode register MMO is “1”, the application corresponding definition structure is used, and after the tablet coordinates (X, Y) are converted to the logical coordinates (x, y),
The logical coordinates (x, y) are converted to the cursor echo position (α, β). When the state is “0”, that is, the mode register MMO is “0”, the system correspondence definition is used, and after the tablet coordinates (X, Y) are converted into the coordinates of the physical screen (cursor echo positions α, β), The coordinates (α, β) are converted into logical coordinates. For this reason, when the application corresponding definition structure is used, the tablet coordinates and the logical coordinates can be determined (defined) by the request of the application program, and the cursor can be present outside the physical screen. . Further, although the cursor displayed on the physical screen is relative movement, the coordinates added to the application program are relative coordinates on the logical screen. And
When the system correspondence definition structure is used, the program used in the conventional system can be executed as it is, and the input process of the relative coordinates is performed despite the addition of the absolute coordinates.

(Operation and Operation) FIG. 11 is a flow chart of the embodiment of the present invention, and FIG. 12 is a diagram for explaining the operation and operation of the embodiment of the present invention.

When the power is turned on (ON), the system, that is, the oprating program is executed, the system corresponding definition program is read from the hard disk device, the tablet mode is initialized, and the system corresponding definition program is activated (S30) (twelfth).
(Figure S1).

In the above-mentioned operation, the system definition body and the application definition body each have a definition register, which means a program for obtaining the cursor position coordinates and the cursor position coordinates on the logical screen from the control information stored in the definition register. If the processing after each definition is read from the definition register is the same, it is shared and provided in the OS program, and the system definition and application definition are composed of the registers shown in Fig. 4 (b). May be done.

Initial processing of the entire system is performed by the processing ST30, and then the operator gives an instruction to start the application and the application from the keyboard (ST3, for example).
1) and then the OS program executes the application program to which the start instruction is added (ST32) (Fig. 12 S
2). Then, the window of the started application program is opened (ST33).

After this window is opened, if this program has a one-to-one correspondence between the logical screen and the physical screen, the application corresponding definition program corresponding to the activated application program stored in the hard disk device 11 in advance is read. Logical screen management unit KL described above
Register with K (ST34). At this point, the application program is being executed, but when the operator enters data from the tablet 9 and the operator switches the tablet mode, that is, the application mode (ST35), the OS program then interrupts. The process (FIG. 4 (c)) performs the transition process (ST36), that is, the switching process from the physical screen corresponding mode (system mode) to the logical screen corresponding mode (app mode), and activates the app corresponding definition object (twelfth). (Figure S3) By this activation, drawings can be input using a tablet (ST37). When the operator finishes inputting drawings, etc., the operator then switches the tablet mode (ST38), which corresponds to the logical screen. The OS program makes a transition from the mode to the physical screen compatible mode (ST39) and activates the system compatible definition structure. (S4 in FIG. 12) After this switching, even if the operator operates the tablet, for example, the cursor moves on the physical screen, and the multi-window screen operation, that is, the tablet 9 is performed.
It is possible to perform the operation (ST40) by the system definition body in. In this operation, the mode is switched from the keyboard when necessary according to the operator's instruction.

FIG. 13 is a diagram for explaining the mapping between the screen image and the tablet coordinates in the embodiment of the present invention for clarifying the correspondence relationship between the physical screen corresponding mode (system mode) and the logical screen corresponding mode (application mode).

When the system starts up, that is, when the embodiment of the present invention is operated by turning on the power, it is in the physical screen mode,
A specific portion of the input area of the tablet 9 corresponds to the physical screen, and a specific area of the logical screen is assigned to one window on the physical screen. At this time, the cursor is displayed as a global arrow cursor and can be moved within the physical screen. For example, when the cursor is designated in the window, the cursor position on the logical screen corresponding to the cursor position is input to the executing application program.

On the other hand, in the logical screen correspondence mode, the cursor becomes a cross-shaped local cursor, a specific area of the tablet 9 is assigned to the logical screen, and a part of the logical screen becomes one window of the physical screen. At this time, the local cursor moves within the corresponding window. And when you move it out of the window, the local cursor disappears from the physical screen. However, it will still exist on the logical screen and its coordinates will be added to the application program. Furthermore, when coordinates outside the specific area of the tablet 9 are input, the coordinates are similarly added to the application program, and even if the coordinates are assigned to one window of the multi-window, the absolute coordinates in the tablet input area are valid. .

Although the above has described in detail with reference to the embodiments of the present invention, the tablet used in the embodiments of the present invention is not limited to this, and may be a digitizer or another device for inputting absolute coordinates.

〔The invention's effect〕

As described above, the present invention is to convert data added from a device for inputting absolute coordinates by control information,
Further, since the control information can be switched, according to the present invention, the application program and the absolute coordinates in the multi-window system can be displayed without deteriorating the use efficiency of the application program that requires the absolute coordinates even in the system using the multi-window. It is possible to obtain an input data control device capable of executing a required application program.
