Description

  The present invention relates to a data input device and a data input method for inputting data using a graphical user interface of a computer, a program for causing a computer to execute the data input method, and a computer-readable storage medium.

  At present, an OS (operating system) and application programs that operate on the OS are mainly those using a GUI (graphical user interface). For example, even when the user inputs input data such as numerical values, a data input method using this GUI is often used.

  For example, in Patent Document 1 below, in order to input two analog values related to each other, current and voltage, by displaying a set point on a graph and limiting the range of the input value within the frame of the graph, Techniques for improving operability and reducing input errors are shown.

  Patent Document 2 below discloses a technique for reflecting a coordinate value instructed from a mouse on a graph and a coordinate value input from a keyboard in a data holding unit and then reflecting them in graphic display and text display. Yes. As a result, data input can be performed without making the user accustomed to layout display and the user accustomed to numerical input feel the inconvenience of operability.

  Further, in the following Patent Document 3, a second input value based on point position coordinate information in the pointer object is set in addition to the position information of the slider and the pointer itself which are display objects moved by the user. Technology is shown.

JP 60-217426 A JP-A-5-298046 Japanese Patent No. 3979156

  For example, when two related setting values such as voltage and current applied to a certain device are simultaneously input using a GUI, a two-dimensional graph is displayed and the position of the operation pointer placed in the graph is displayed. It is natural to use the coordinates X and Y as set values for voltage and current.

  In this case, since the movement range of the operation pointer is limited to the upper, lower, left, and right frames of the graph, the graph frame is considered to represent the upper and lower limits of values that can be taken by the voltage and current, respectively. It is done. The coordinate position or set value indicated by the operation pointer is displayed by simultaneously displaying a scale serving as an index of input data of each of the coordinate axes X and Y and displaying an auxiliary line in a direction perpendicular to the scale from the position of the operation pointer. Can be easily read by the user.

  The user usually moves the operation pointer by superimposing a cursor of a graphical selection device such as a mouse on the operation pointer and performing an operation called dragging to move the mouse while holding down the mouse button. In addition, the user can usually move to a place where the operation pointer is clicked at once by performing an operation called a click of pressing the mouse button at an arbitrary position in the graph display area.

However, when a value is input using the operation pointer as described above, once the operation pointer is moved, the original value (default value) set in advance, that is, when an input graph is newly displayed on the screen There is a problem that it becomes difficult to know which value (position) the set value represented by the operation pointer is set to.
If it is desired to return to the original value, it is troublesome because it is necessary to operate the reset button or the like to return to the initial screen.

  In addition, for example, when a specific relationship is recognized between an appropriate voltage and current due to the characteristics of the device, the values that can be taken as the default values are not one set, but are expressed as a function of the X coordinate value and the Y coordinate value. Will be. However, when there are many combinations of default values in this way, unlike the case where a single default value is specified, an arbitrary default value is selected from among a plurality of default values by operating the operation pointer. Had the problem of being difficult.

  Furthermore, there is a problem that it is difficult for the user to set two input data based on the X coordinate value and the Y coordinate value of the operation pointer in consideration of an input possible range including a plurality of predetermined value sets. It was.

  The present invention has been made in view of such problems, and an object of the present invention is to make it possible to input optimal input data based on movement of an operation pointer with a simple operation.

In order to solve the above-described problems, the present invention provides a two-dimensional region defined by X and Y coordinates in a data input device for inputting data using a graphical user interface of a computer. A graph display area including an operation pointer indicating a designated position in the area, an X-axis slide bar display area provided with an X-axis slider corresponding to the X-coordinate position of the operation pointer, and the Y-coordinate of the operation pointer Display means for displaying a display screen including a Y-axis slide bar display area provided with a Y-axis slider corresponding to the position, and an operation pointer display position for detecting a change in the display position of the operation pointer due to an operation of the input device Detecting a change in the display position of the X-axis slider or the Y-axis slider due to operation of a detection means and an input device Of the two input data determined based on the X-coordinate value and the Y-coordinate value of the operation pointer in the graph display area, one input data is defined in advance as a function of the other input data. A default value line display control means for performing control to display a default value line based on the default value in the graph display area; one of the operation pointer display position detection means and the display position detection means of the slider display position detection means; A data input device or the like having display position change control means for performing control to change the display position of the detection target in the other display position detection means according to the relationship with the display position detected in step 1 and the predetermined value line I will provide a.
The present invention also includes a data input method using the above-described data input device, a program for causing a computer to execute the data input method, and a computer-readable storage medium storing the program.

Any hardware configuration may be used. For example, computer devices applicable to the data input device 100 include various types of devices such as machine control devices, medical devices, PDAs (personal data assistants), handy terminals, telephones, game machines, electrical appliances, and other dedicated devices. The device is applicable.

  The data input device 100 has hardware configurations of a data input device main body 110, a display 120, a keyboard 130, and a pointing device 140, and inputs data using a computer graphical user interface.

  The data input device main body 110 has a hardware configuration including a CPU 111, a ROM 112, a RAM 113, an external storage device 114, a network I / F 115, a display I / F 116, an input device I / F 117, and a system bus 118. .

  A CPU (Central Processing Unit) 111 controls the entire data input device 100 in an integrated manner.

  A ROM (Read Only Memory) 112 is a read-only storage device that stores various data such as programs and parameters that do not need to be changed. Instead of this ROM, a memory backed up by a battery may be configured so that data is not erased.

  A RAM (Random Access Memory) 113 is a storage device that temporarily stores programs and data supplied from an external device or the like. The RAM 113 is also used for holding data developed for display on the screen of the display 120. The display data expanded in the RAM 113 is displayed on the screen of the display 120 via the display I / F 116.

  The external storage device 114 stores, for example, a program executed by the OS and the CPU 111, and data known in the description of the present embodiment (for example, control data, created document data, image data, and other files), and the like. It is a storage device. Further, as the external storage device 114, a hard disk, a memory card, an optical disk such as a flexible disk (FD) and a compact disk (CD) that can be detached from the data input device main body 110, a magnetic card, an optical card, an IC card, a memory card, etc. Can be applied. When the external storage device 114 is a storage device that is detachable from the data input device main body 110, it is also used for distributing stored programs and data.

  The network I / F 115 is an interface for connecting to a network line such as the Internet via a communication line based on the control of the CPU 111. Specifically, the network I / F 115 is used to transmit / receive various data to / from an external device connected to the network line, and to download a program from the external device.

  The display I / F 116 is an interface that controls display on the display 120 that displays data held by the data input device 100, data supplied from an external device, and the like based on the control of the CPU 111.

  The input device I / F 117 is an interface that manages input of input data from input devices such as the keyboard 130 and the pointing device 140 operated when the user inputs data.

  The system bus 118 connects the units 111 to 117 in the data input device main body 110 so that they can communicate with each other.

  The display 120 displays various data using the display I / F 116.

  The keyboard 130 is composed of a plurality of character keys and arrow keys, and is used when the user inputs various data.

  The pointing device 140 is used when a user gives a selection instruction using a cursor displayed on the screen of the display 120. The pointing device 140 is an appropriate graphical selection device such as a mouse, a light pen, a tablet, or a touch panel installed on the surface of the display 120. The pointing device 140 includes a click mechanism and a drag mechanism. When a click operation and a drag operation are performed by a user operation, the pointing device 140 transmits the operation information to the CPU 111 through the input device I / F 117. The drag mechanism can also be realized by an operation in which the user moves the graphical selection device while pressing the click mechanism.

  In the present embodiment, a program for executing the processing of the present invention (screen display processing in FIGS. 2 to 6 and 8 described later, processing in the flowchart in FIG. 7 and the like) is stored in advance in an external storage device. 114 is stored. Further, the present invention is not limited to the form in which the program for executing the processing of the present invention is stored in the external storage device 114, but can be applied to the form stored in the ROM 112, for example. Further, a program for executing the processing of the present invention via the communication line by the network I / F 115 may be stored in the external storage device 114. Then, the above program is loaded (expanded) in the RAM 113 by predetermined control, and the CPU 111 controls each device of the data input device 100 to execute the processing of the present invention. Alternatively, a program received from another computer via the network I / F 115 may be directly loaded into the RAM 113 without being temporarily stored in the external storage device 114.

  FIG. 2 is a schematic diagram illustrating an example of a display screen 200 displayed on the display 120 illustrated in FIG. 1 according to the first embodiment of this invention. The display control of the display screen 200 shown in FIG. 2 is realized by the CPU 111 shown in FIG. 1 executing a program stored in the external storage device 114.

  The display screen 200 shown in FIG. 2 includes display objects such as a mouse cursor 210, a graph display area 220, an X-axis slide bar 230, a Y-axis slide bar 240, an X-axis numeric display area 250, and a Y-axis numeric display area 260. Is configured. Each display object displayed on the display screen 200 is temporarily stored in, for example, the RAM 113 and displayed on the display 120 which is a display unit via the display I / F 116.

  The mouse cursor 210 can be freely moved in the display screen 200 by the user operating the pointing device 140 (or the keyboard 130). The user can issue a selection instruction to the display object by clicking or dragging the pointing device 140 using the mouse cursor 210. Here, in the present embodiment, it is assumed that the upper left coordinates of the arrow-shaped figure representing the mouse cursor 210 are handled as the coordinates of the mouse cursor 210.

  The graph display area 220 is a display area that is a two-dimensional area defined by the X coordinate and the Y coordinate and includes an operation pointer 224 that indicates a designated position in the two-dimensional area. Specifically, the graph display area 220 includes its coordinate base point 221, X-axis scale 222, Y-axis scale 223, operation pointer 224, default value position display unit 225, default value line 226, input possible range boundary line 227, X A value auxiliary line 228 and a Y value auxiliary line 229 are shown.

  Here, the user moves the mouse cursor 210 so as to overlap the operation pointer 224, and performs an operation (drag operation) to move the mouse cursor 210 while clicking the mouse pointer 210, thereby moving the operation pointer 224 in the graph display area 220. Can be made. In the present embodiment, the coordinates of the center of a perfect circle representing the operation pointer 224 are handled as the coordinates of the operation pointer 224. At this time, the CPU 111 performs processing for detecting a change in the display position of the operation pointer 224 based on the relative coordinates from the coordinate base point 221 at the display position of the operation pointer 224. The CPU 111 that performs this detection processing constitutes an operation pointer display position detection unit. Further, the CPU 111 calculates input values X and Y which are two input data corresponding to the X-axis scale 222 (X-coordinate value) and the Y-axis scale 223 (Y-coordinate value) of the operation pointer 224. The CPU 111 that performs this calculation processing constitutes input data calculation means. Here, since the calculation method of the input value using the graph coordinates and the scale is a known technique, the description thereof is omitted.

  The X-axis slide bar (X-axis slide bar display area) 230 is provided with an X-axis slider 231 corresponding to the X-coordinate position of the operation pointer 224. The display position of the X-axis slider 231 is determined by the mouse cursor 210. It can be moved by dragging. At this time, the CPU 111 calculates an input value X (input data X) according to the display position of the X-axis slider 231 corresponding to the X-axis scale 222.

  The Y-axis slide bar 240 (Y-axis slide bar display area) is provided with a Y-axis slider 241 corresponding to the Y-coordinate position of the operation pointer 224. The display position of the Y-axis slider 241 is determined by the mouse cursor 210. It can be moved by dragging. At this time, the CPU 111 calculates an input value Y (input data Y) according to the display position of the Y-axis slider 241 corresponding to the Y-axis scale 223.

  Here, in this embodiment, the barycentric coordinates of a square figure representing the X-axis slider 231 and the Y-axis slider 241 are treated as the respective coordinates. Then, when the X-axis slider 231 or the Y-axis slider 241 is operated by the pointing device 140, the CPU 111 performs processing for detecting a change in the display position of the operated slider. The CPU 111 that performs this detection processing constitutes a slider display position detection unit.

  The X-axis numerical value display area 250 is configured to display the input value X calculated from the display position of the operation pointer 224 and to be used for numerical value input for designating the X-axis display position of the operation pointer 224. ing. The Y-axis numerical value display area 260 displays the input value Y calculated from the display position of the operation pointer 224, and can also be used for numerical input for designating the Y-axis display position of the operation pointer 224. It is configured. The X-axis numerical value display area 250 and the Y-axis numerical value display area 260 correspond to an input data display area.

  The default value position display unit 225 of the graph display area 220 displays the original value (default value) preset by the system / application applied to the present embodiment, that is, the previous value when the display screen 200 is newly displayed. The position where the operation pointer 224 was displayed on the display screen is shown. Specifically, the default value is one of the two input values (input data) determined based on the value of the X coordinate and the value of the Y coordinate of the operation pointer 224 in the graph display area 220. Is defined in advance as a function of This default value may be different for each system / application, or may be separately designated in advance by the user. Then, the CPU 111 performs control to display a default value line 226 based on this default value in the graph display area 220. The CPU 111 that performs this display control constitutes a default value line display control means.

  Here, in the present embodiment, the input value X and the input value Y are not mutually independent values, and there is a desirable combination of values between the two values, and one input value is assigned to the other value. Suppose that it is possible to define continuously as a function of input values. Such a relationship includes, for example, a relationship between tube voltage and tube current in the X-ray irradiation apparatus. When such a relationship holds, a default value line 226 representing a predetermined default value is displayed as shown in FIG. Here, FIG. 2 shows a case where the relationship of Y = (X−10) / 5 mA is satisfied when 0 <X ≦ 80 kV, and Y = 14 mA is satisfied when 80 <X ≦ 120 kV. Such a default value line 226 can be defined, for example, by sequentially connecting n coordinate values (X, Y) of X (n) <X (n + 1) by linear interpolation. In the example illustrated in FIG. 2, the default value line 226 is illustrated as a straight line, but may be a curved line, for example.

  In addition, as the input value X and the input value Y, not only the upper limit value and the lower limit value can be defined as independent values, but there are cases where it is desired to limit the input value in the combination of the input value X and the input value Y. . For example, in the relationship between the tube voltage and the tube current of the X-ray irradiation apparatus described above, it is conceivable to limit the maximum power that can be given to the X-ray irradiation apparatus. Alternatively, it is conceivable to provide a certain adjustment range with respect to a predetermined default value indicated by the default value line 226.

  The input possible range boundary line 227 indicates a boundary line of a range of input values (input possible range) that can be given to the apparatus in such a case. In other words, the input possible range boundary line 227 defines an input possible range for two input values (input data) determined based on the X coordinate value and the Y coordinate value of the operation pointer 224 in the graph display area 220. Such an inputable range boundary line 227 can be defined as a polygonal region having n vertices, for example. Then, the CPU 111 performs control to display the input possible range boundary line 227 in the graph display area 220. The CPU 111 that performs this display control constitutes a boundary line display control means.

  The X value auxiliary line 228 and the Y value auxiliary line 229 are for making it easy to read the input value corresponding to the display position of the operation pointer 224 on the X axis scale 222 or the Y axis scale 223. It is good also as non-display by a user's setting.

  Next, a first operation example when the user drags the operation pointer 224 will be described with reference to FIG.

FIG. 3 is a schematic diagram illustrating a first operation example when the user drags the operation pointer 224 illustrated in FIG. 2 according to the first embodiment of this invention.
3, FIG. 3A, FIG. 3B, and FIG. 3C show the same screen area, and time-series display in the order of FIG. 3A, FIG. 3B, and FIG. 3C. It is a thing. Also, the display control of the display screen shown in FIG. 3 is realized by the CPU 111 shown in FIG. 1 executing a program stored in the external storage device 114.

  First, in FIG. 3A, consider a case where the user operates the mouse cursor 210, clicks the operation pointer 224, and then drags and moves it in the horizontal direction 301. When the user operates the operation pointer 224, the CPU 111 reads the new coordinate value in the X-axis direction and performs display control to change the display position of the X-axis slider 231 to the corresponding position on the X-axis slide bar 230. . Therefore, as shown in FIG. 3B, when the operation pointer 224 is horizontally moved to a position where it overlaps the predetermined value line 226, the X-axis slider 231 is also moved horizontally on the X-axis slide bar 230 by the same distance. Is displayed.

  When the user further continues the drag operation in the horizontal direction 302 from the state of FIG. 3B, the CPU 111 moves and displays the operation pointer 224 at the position shown in FIG. The slider 231 also controls to move and display the corresponding X-axis position horizontally.

  As described above, FIG. 3 illustrates the case where the operation of moving the operation pointer 224 in the X-axis direction has been described. However, the case of performing the operation of moving the operation pointer 224 in the Y-axis direction is similar by reading the X-axis and the Y-axis together. Therefore, the description thereof is omitted.

  Next, a first operation example when the user drags the X-axis slider 231 will be described with reference to FIG.

FIG. 4 is a schematic diagram illustrating a first operation example when the user drags the X-axis slider 231 illustrated in FIG. 2 according to the first embodiment of this invention.
In FIG. 4, FIGS. 4 (a), 4 (b), and 4 (c) show the same screen area, and time-series display in the order of FIGS. 4 (a), 4 (b), and 4 (c). It is a thing. Further, the display control of the display screen shown in FIG. 4 is realized by the CPU 111 shown in FIG. 1 executing a program stored in the external storage device 114.

  First, in FIG. 4A, consider a case where the user operates the mouse cursor 210 and clicks the X-axis slider 231 and then drags it as it is to move it in the horizontal direction 401. When the user operates the X-axis slider 231, the CPU 111 reads the coordinate value in the X-axis direction and performs display control to change the display position of the operation pointer 224 to the corresponding X-coordinate position. At this time, as shown in FIG. 4B, the display position of the operation pointer 224 is changed while maintaining the Y-axis coordinate value until the operation pointer 224 overlaps the predetermined value line 226.

  However, if the user continues to drag the X-axis slider 231 in the horizontal direction 402 from the state shown in FIG. 4B, the CPU 111 sets the new X-coordinate of the X-axis slider 231 shown in FIG. A new coordinate position 403 applied to the operation pointer 224 is calculated. However, since the new coordinate position 403 is not on the default value line 226, the CPU 111 changes the display position of the operation pointer 224 to a position where the default value line 226 and the X value auxiliary line 228 intersect. At this time, if there is no point where the default value line 226 and the X value auxiliary line 228 intersect, the CPU 111 determines the Y coordinate of the local maximum point in the X axis direction of the default value line 226 and the X coordinate of the X value auxiliary line 228. And the new coordinates of the operation pointer 224.

  As described above, FIG. 4 illustrates the case where the X-axis slider 231 is operated. However, when the Y-axis slider 241 is operated, the same operation is realized by rereading the X axis and the Y axis. The description is omitted.

  3 and 4 described above, the CPU 111 performs display control for changing the display positions of the operation pointer 224 and the operation slider (X-axis slider 231) in consideration of the relationship with the default value line 226. Specifically, the CPU 111 determines the display position of the other detection target in accordance with the display position after the change of the detection target of one of the operation pointer 224 and the X-axis slider 231 and the relationship with the default value line 226. The control to change is performed. More specifically, when the operation pointer 224 is displayed on the default value line and the display position after the change of the operation pointer 224 is deviated from the default value line by the operation of the input device, the CPU 111 (FIG. 4 (c)), the display position of the operation pointer 224 is controlled to be changed to a predetermined position on the default value line (the position shown in FIG. 4C). The CPU 111 that performs this change control constitutes a first display position change control means.

  Next, a second operation example when the user drags the operation pointer 224 will be described with reference to FIG.

FIG. 5 is a schematic diagram illustrating a first operation example when the user drags the operation pointer 224 illustrated in FIG. 2 according to the first embodiment of this invention.
In FIG. 5, FIGS. 5 (a), 5 (b), and 5 (c) show the same screen area, and time-series display in the order of FIGS. 5 (a), 5 (b), and 5 (c). It is a thing. The display control of the display screen shown in FIG. 5 is realized by the CPU 111 shown in FIG. 1 executing a program stored in the external storage device 114.

  First, in FIG. 5A, consider a case where the user operates the mouse cursor 210, clicks the operation pointer 224, and then drags and moves it in the horizontal direction 501. When the user operates the operation pointer 224, the CPU 111 reads the new coordinate value in the X-axis direction and performs display control to change the display position of the X-axis slider 231 to the corresponding position on the X-axis slide bar 230. . For this reason, as shown in FIG. 5B, when the operation pointer 224 moves horizontally to a position where it overlaps the input possible range boundary line 227, the X-axis slider 231 also horizontally moves on the X-axis slide bar 230 by the same distance. Moved and displayed.

  When the user further engages in the drag operation in the horizontal direction 502 from the state of FIG. 5B, the CPU 111 detects a new coordinate position 503 shown in FIG. However, since the new coordinate position 503 is outside the input possible range, the CPU 111 does not change the display position of the operation pointer 224 from the position in FIG. 5B and keeps it on the input possible range boundary line 227. Process. In this case, since the position of the operation pointer 224 does not change, the position of the X-axis slider 231 does not change.

  As described above, FIG. 5 illustrates the case where the operation of moving the operation pointer 224 in the X-axis direction has been described. Therefore, the description thereof is omitted.

  Next, a second operation example when the user drags the X-axis slider 231 will be described with reference to FIG.

FIG. 6 is a schematic diagram illustrating a second operation example when the user drags the X-axis slider 231 illustrated in FIG. 2 according to the first embodiment of this invention.
6A, 6B, and 6C show the same screen area, and time-series display is performed in the order of FIGS. 6A, 6B, and 6C. It is a thing. Further, the display control of the display screen shown in FIG. 6 is realized by the CPU 111 shown in FIG. 1 executing a program stored in the external storage device 114.

  First, in FIG. 6A, consider a case where the user operates the mouse cursor 210 and clicks the X-axis slider 231 and then drags it to move in the horizontal direction 601. When the user operates the X-axis slider 231, the CPU 111 reads the coordinate value in the X-axis direction and performs display control to change the display position of the operation pointer 224 to the corresponding X-coordinate position. At this time, as shown in FIG. 6B, the display position of the operation pointer 224 is changed while maintaining the Y-axis coordinate value until the operation pointer 224 overlaps the input possible range boundary line 227.

  However, if the user continues to drag the X-axis slider 231 in the horizontal direction 602 from the state of FIG. 6B, the CPU 111 sets the new X-coordinate of the X-axis slider 231 shown in FIG. A new coordinate position 603 applied to the operation pointer 224 is calculated. In this case, since the new coordinate position 603 is outside the input range, the CPU 111 causes the display position of the operation pointer 224 to intersect the input range boundary 227 and the X value auxiliary line 604 corresponding to the new coordinate position 603. Try to change to position. However, since such a point does not exist in FIG. 6C, the CPU 111 instead obtains the coordinates of the maximum point 605 in the X-axis direction of the input possible range boundary line 227 and moves the operation pointer 224 to the maximum point 605. Change to the position of and display. At the same time, the CPU 111 applies the X coordinate of the new display position 605 of the operation pointer 224 to the X coordinate of the X axis slider 231 to change and display the display position of the X axis slider 231.

  As described above, FIG. 6 illustrates the case where the X-axis slider 231 is operated. However, when the Y-axis slider 241 is operated, the same operation is realized by rereading the X-axis and the Y-axis. The description is omitted.

  5 and 6, the CPU 111 performs display control for changing the display positions of the operation pointer 224 and the operation slider (X-axis slider 231) in consideration of the relationship with the input possible range boundary line 227. . Specifically, the CPU 111 displays the other detection target according to the display position after the change of one of the operation pointer 224 and the X-axis slider 231 and the relationship with the input possible range boundary line 227. Control to change the position is performed. More specifically, when the operation pointer 224 is displayed within the input-capable range, the CPU 111 changes the display position of the operation pointer 224 outside the input-capable range by operating the input device. (FIG. 5C, FIG. 6C), the display position of the operation pointer 224 is set to a predetermined position on the input possible range boundary line (the position shown in FIG. 5C, FIG. 6C). Control to change to. The CPU 111 that performs this change control constitutes a second display position change control means.

  Next, based on the above examples of FIGS. 3, 4, 5, and 6, the data input method according to the present embodiment including the calculation method of the display position of the operation pointer 224 is according to the flowchart of FIG. I will explain.

  FIG. 7 is a flowchart showing an example of the processing procedure of the data input method by the data input device 100 according to the first embodiment of the present invention. The flowchart shown in FIG. 7 is realized by the CPU 111 shown in FIG. 1 executing a program stored in the external storage device 114.

  First, in step S701, the CPU 111 performs processing for detecting a mouse click of the pointing device 140 by the user.

  Subsequently, in step S <b> 702, the CPU 111 performs a process of detecting that the user has shifted to the drag operation while the pointing device 140 is being clicked by the mouse. Here, once the start of the drag is detected, it is possible to repeatedly detect the amount of mouse movement within a minute time until the drag operation is canceled and to calculate the new coordinates of the drag target.

  In step S703, the CPU 111 determines whether the drag target is the operation pointer 224 or the slider (231 or 241).

As a result of the determination in step S703, if the drag target is the operation pointer 224, the process proceeds to step S704.
In step S704, the CPU 111 performs processing for detecting a drag operation on the operation pointer 224 of the pointing device 140 by the user.

  Subsequently, in step S705, the CPU 111 performs a process of detecting a new coordinate of the operation pointer 224.

  Subsequently, in step S <b> 706, the CPU 111 determines whether or not the new coordinates detected in step S <b> 705 are within the input possible range based on the input possible range boundary line 227.

As a result of the determination in step S706, if the new coordinates detected in step S705 are not within the inputable range (outside the inputable range), the process proceeds to step S707.
In step S707, the CPU 111 performs a process of calculating an intersection coordinate between the line segment connecting the old coordinate and the new coordinate of the operation pointer 224 (the locus segment of the operation pointer 224) and the input possible range boundary line 227. .

  Subsequently, in step S708, the CPU 111 sets the value of the intersection coordinate (intersection coordinate value) calculated in step S707 as a new coordinate value of the operation pointer 224.

  If the process in step S708 is completed, or if it is determined in step S706 that the new coordinates detected in step S705 are within the input allowable range, the process proceeds to step S709.

  In step S709, the CPU 111 performs display control to apply the new coordinate value (new coordinate value) to the operation pointer 224 and display the operation pointer 224 at the new coordinate position based on the new coordinate value.

  In step S710, the CPU 111 applies the X coordinate value of the new coordinate to the X axis slider 231 to change and display the display position of the X axis slider 231, and simultaneously displays the Y coordinate value of the new coordinate on the Y axis slider 241. Applying it, the display position of the Y-axis slider 241 is changed and displayed.

  Subsequently, in step S711, the CPU 111 determines whether or not the user is dragging the pointing device 140.

  If the result of determination in step S711 is that the drag operation is ongoing, processing returns to step S704, and processing from step S704 onward is performed again. The loop processing of steps S704 to S711 is repeated until the drag operation is released.

  On the other hand, as a result of the determination in step S711, when the drag operation is not continuing (drag operation is canceled), the processing in the flowchart of FIG.

  If the result of determination in step S703 is that the drag target is a slider (231 or 241), processing proceeds to step S712. Here, in the following description, an example in which the drag target is the X-axis slider 231 will be described.

  In step S712, the CPU 111 performs processing for detecting a drag operation on the X-axis slider 231 of the pointing device 140 by the user.

  Subsequently, in step S713, the CPU 111 performs a process of detecting a new X coordinate of the X-axis slider 231.

  Subsequently, in step S714, the CPU 111 sets the new X coordinate value detected in step S713 and the Y coordinate value of the operation pointer 224 to be the new coordinate value of the operation pointer 224.

  Subsequently, in step S <b> 715, the CPU 111 determines whether or not the line connecting the old coordinate and the new coordinate of the operation pointer 224 (the locus line segment of the operation pointer 224) and the default value line 226 intersect.

As a result of the determination in step S715, if the trajectory line segment of the operation pointer 224 intersects the default value line 226, the process proceeds to step S716.
In step S716, the CPU 111 calculates the intersection coordinates of the X value auxiliary line 228 and the default value line 226 based on the new X coordinate value. At this time, if there is no intersection, the CPU 111 calculates the maximum point coordinate of the default value line 226 in the X-axis direction. That is, in step S716, the CPU 111 determines the intersection point coordinates of the auxiliary line based on the new coordinate value of the X-axis slider 231 being operated and the default value line 226, or the default value line 226 in the operation axis direction (X-axis direction). Calculate the local maximum coordinates.

  Subsequently, in step S717, the CPU 111 newly sets the intersection coordinate value (intersection coordinate value) or the maximum point coordinate value (maximum point coordinate value) calculated in step S716 as a new coordinate value of the operation pointer 224. Perform the process.

  Subsequently, in step S718, the CPU 111 determines whether or not the new coordinates set in step S717 are within the input possible range based on the input possible range boundary line 227.

As a result of the determination in step S718, if the new coordinates set in step S717 are not within the inputable range (outside the inputable range), the process proceeds to step S719.
In step S719, if the line segment connecting the old coordinate and the new coordinate of the operation pointer 224 (the trajectory line segment of the operation pointer 224) and the input possible range boundary line 227 intersect with each other, the CPU 111 Is calculated. Further, when the locus segment of the operation pointer 224 and the input possible range boundary line 227 do not intersect with each other, the CPU 111 calculates the maximum point coordinates of the input possible range boundary line 227 in the X-axis direction.

In addition, it can be said that the process of this step S719 performs the process shown below.
That is, the CPU 111 determines the intersection coordinates of the auxiliary line based on the new coordinate value of the X-axis slider 231 being operated and the input allowable range boundary line 227 or the input allowable range boundary line 227 in the operation axis direction (X-axis direction). Calculate the local maximum coordinates.

  Subsequently, in step S720, the CPU 111 newly sets the intersection coordinate value (intersection coordinate value) or the maximum point coordinate value (maximum point coordinate value) calculated in step S720 as a new coordinate value of the operation pointer 224. Set up.

  When the process of step S720 is completed, when it is determined at step S715 that the locus line segment of the operation pointer 224 and the default value line 226 do not intersect, or at step S718, it is determined that the new coordinates are within the inputable range. If so, the process proceeds to step S721.

  In step S721, the CPU 111 performs display control to display the operation pointer 224 at the new coordinate position by applying the calculated new coordinate to the operation pointer 224.

  In step S722, the CPU 111 applies the X coordinate value of the new coordinate to the X axis slider 231 to change and display the display position of the X axis slider 231, and simultaneously displays the Y coordinate value of the new coordinate on the Y axis slider 241. Applying it, the display position of the Y-axis slider 241 is changed and displayed.

  Subsequently, in step S723, the CPU 111 determines whether the drag operation of the pointing device 140 by the user is ongoing.

  If the result of the determination in step S723 is that the drag operation is ongoing, the process returns to step S712, and the processing from step S712 onward is performed again. The loop processing of steps S712 to S723 is repeated until the drag operation is released.

  On the other hand, if the result of the determination in step S723 is that the drag operation is not continuing (the drag operation has been canceled), the processing in the flowchart of FIG. 7 is terminated.

  In the description of steps S712 to S723 in FIG. 7 described above, the case where the drag target is the X-axis slider 231 has been described. However, in this embodiment, the drag target is the Y-axis slider 241. The case is also applicable. In this case, the same operation can be realized by replacing the X axis and the Y axis with each other in the description of steps S712 to S723 in FIG.

  Further, in the processing of steps S710 and S722 of FIG. 7, a numerical value obtained by applying the X-axis scale 222 to the X-coordinate value is displayed in the X-axis numerical value display area 250, and a numerical value obtained by applying the Y-axis scale 223 to the Y coordinate value May be displayed in the Y-axis numerical value display area 260.

  Further, when a numerical character string is input from the keyboard 130 or the like by the user to the X-axis numerical value display area 250 and the Y-axis numerical value display area 260, the CPU 111 is instructed to input new coordinates of the input axis slider. May be determined. In this case, the CPU 111 may treat the new coordinate value obtained by applying the corresponding axis scale as the new coordinate value detected in step S713, and execute steps S714 to S722.

  As described above, according to the first embodiment, when the user directly operates the operation pointer 224, the operation pointer 224 is moved to an arbitrary position only within the input possible range boundary line 227. Can do. Thereby, it becomes possible to always input input data of combinations of values in an appropriate range.

In addition, when the user is operating the slider of each axis, the operation pointer 224 is moved along the X-axis or Y-axis direction and the operation pointer 224 is moved along the default value line without any special switching operation. The operation to be performed can be switched continuously and automatically. Thereby, an arbitrary predetermined value can be easily selected. Also, there is an effect that the difference between the default value and the current input value can be easily grasped visually by the positional relationship between the default value line and the operation pointer. Furthermore, since the display positions of the slider and the operation pointer can be changed by inputting a numerical value, it is possible to specify a fine value that is difficult to specify with the GUI. Therefore, it is possible to provide a data input device capable of easily selecting an arbitrary default value without hindering the setting of free input data by moving the operation pointer.
That is, according to the first embodiment, it is possible to input optimum input data based on the movement of the operation pointer with a simple operation.

In the present embodiment, the auxiliary line 801 is not actually displayed. May be.

  When the user drags the power amount operation pointer 811 using the mouse cursor 210, the CPU 111 performs control to move and display the X-axis slider 231 and the Y-axis slider 241 by equal amounts according to the above-described relationship of W = XkV × YmA. Do. As a result, the operation pointer 224 moves in the direction of 45 degrees in the example shown in FIG. However, when this movement vector intersects with the default value line 226, the CPU 111 performs control to move and display the operation pointer 224 along the default value line 226 to a position satisfying the above-described relationship of W = XkV × YmA. .

  As described above, according to the second embodiment, in addition to the two input numerical values of the tube voltage and the tube current, the power amount derived from these physical amounts is displayed on the power amount slide bar 810 in accordance with it.
