2. Description of the Related Art Graphic processing in various graphic devices such as a computer, CAD, and CG graphic devices.
When performing line drawing, shape design, and the like, various function adjustment processing operations of a cursor used as a drawing tool frequently occur. For example, in the design of a graphic using a drawing tool or a paint tool, when a cursor is provided with a pen function, various parameter adjustment processes such as changing the thickness of a line to be drawn frequently occur.

For example, there are various user interfaces for executing a process of adjusting the thickness of a pen corresponding to a cursor. However, in the conventional interface configuration, the operation for executing the adjustment is difficult for a user to understand or is easy to use. May be bad, or some experience may be required to make the desired thickness selection. For these reasons, there is a need for a more user-friendly graphical user interface for adjusting the function of the cursor.

FIG. 14 shows a conventional configuration example of a user interface for adjusting the thickness of a pen. FIG. 14 (a)
Has a slider 1401, a text box 1402 for displaying a numerical value, and a button 1403 for finely adjusting the numerical value.

The user uses the cursor to move the slider 1
The thickness of the pen can be adjusted by dragging 401 to the left or right. In addition, it is also possible to input a numerical value directly into the text box 1402 for adjustment. The problem with this conventional example is that it is not possible to visually check the thickness of the pen after adjustment before making adjustments, and the user is required to experience trial and error operations or to gain experience until operations can be performed quickly. It is required to pinch.

Further, the pen change window shown in FIG. 14B has a visual menu indicating the thickness of a plurality of pens. The user can adjust the thickness of the pen by selecting one menu using the cursor. An advantage of this conventional example is that the thickness of the pen after adjustment can be visually confirmed in advance. This allows you to quickly select the desired thickness without gaining experience. However, this conventional configuration has a problem that continuous thickness values cannot be selected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, there is provided a system having a graphical user interface controller of the present invention.
A dimensional CAD system will be described. It should be noted that the graphical user interface control device and the graphical user interface control method of the present invention provide a two-dimensional CA.
Not only the D system, but also other devices capable of drawing processing,
For example, the present invention can be applied to a drawing device using a personal computer, and can also be applied to a three-dimensional graphic processing device.

First, referring to FIG. 1 and FIG. 2, a process for drawing a graphic on a display in a two-dimensional CAD system having a graphical user interface control device of the present invention and a cursor displayed on the display are used. An example of a pen thickness selection, that is, an example of a drawing line width selection processing screen will be described.

As shown in FIG. 1A, a screen displayed in the CAD system includes a cursor 101 corresponding to the pen and a canvas corresponding to the paper, as in the case of drawing a picture on the paper using the pen. 102 is displayed. The user
For example, a line image 103 can be drawn on the canvas 102 using the cursor 101. The user draws the current line drawing 1
To draw a line drawing thicker than 03, the user can change the size of the cursor 101 to change the thickness of the line drawing.

To change the thickness of the line, the cursor 101 is moved to the position of the box area 104 displayed on a partial area of the display as shown in FIG.
When the cursor 101 enters the box area 104, an indicator 105 is displayed and the mode of the cursor 101 switches from the drawing mode to the cursor size changing mode. The switching of these modes is controlled by the control means based on the coordinate position obtained from the cursor. The control means will be described later. The control means controls the cursor size change mode when the cursor 101 is within the box area 104 and the drawing mode when the cursor 101 is outside the box area 104, that is, the canvas 102 area.

When the cursor 101 is in the box area 104, the indicator 105 is displayed. When the cursor 101 is moved rightward in this state, the cursor 101 is moved according to the shape of the indicator 105 as shown in FIG. Size becomes larger. The indicator 105 is configured so that its width (the distance in the vertical direction in the figure) is continuously different from one end to the other end, and the cursor 101 is a circle having the same diameter as the width of the indicator 105. Is controlled as a pen capable of drawing a line having a thickness corresponding to the circle. The cursor position in FIG. 2C has moved to the right from the cursor position shown in FIG. That is, the cursor 101 has moved to a wider position of the indicator 105, and the cursor 101
Is also increased in accordance with the width of the indicator 105.

The cursor 10 is positioned at the position shown in FIG.
After moving the cursor 101, as shown in FIG.
Is returned to the canvas 102, the mode of the cursor 101 shifts from the cursor size changing mode to the drawing mode, and a new line drawing can be drawn. The thickness of the line image 106 to be drawn at this time is the thickness having the same diameter as the width of the indicator 105 set in FIG. 2C, that is, the thickness of the drawing pen corresponding to the cursor whose size has increased. When the cursor 101 moves out of the box area 104 and the mode of the cursor 101 is switched from the cursor resizing mode to the drawing mode, the indicator 1
05 disappears.

As described above, according to the graphical user interface control device of the present invention, by moving the position of the cursor 101 in the box area 104, the indicator 105 having a continuously changing width is displayed and the cursor is moved. Switch from drawing mode to resize mode. In this state, the cursor 101 is moved to the indicator 10.
By moving on 5, the size of the cursor, that is, the thickness of the pen, can be changed continuously.

In the above-described example, the configuration is shown in which the size of the cursor is changed to change the thickness of the line to be drawn.
The user interface control device according to the present invention has a configuration capable of executing not only the size of the cursor but also various drawing parameter changing processes set corresponding to the cursor. For example, the present invention can be applied to processing for changing a drawing color and a drawing density.
The user interface control device of the present invention displays an indicator for visually executing a change process of a drawing parameter set corresponding to the cursor, and moves the cursor along the indicator to correspond to the cursor. Execute the process of changing the drawing parameters to be set. The indicator has a continuous display mode change area corresponding to various drawing parameters such as shape, density, or color, and changes the display parameter of the indicator according to the drawing parameter set in the cursor according to the cursor movement. The update process is executed in response to the request. In the following embodiment, a processing mode for changing the thickness of a line to be drawn as one of the drawing parameters will be described as a representative.

The hardware configuration for realizing the graphical user interface control device of the present invention will be described with reference to FIGS. Display 303 shown in FIG.
The graphical user interface displayed by
The control means, specifically, for example, is generated in the computer 302. The cursor displayed on the display 303 is controlled by the pointing device 301. The pointing device 301 is, specifically, a device such as a mouse or a tablet provided with a sensor for utilizing a two-dimensional or three-dimensional position and several buttons. The computer 302 is configured by a general personal computer, a game machine, or the like. For example, drawing data, drawing data, and other software data are input to and output from the computer 302 as a control unit by a detachable storage device such as a floppy (registered trademark) disk drive or a network device such as the Internet. It is equipped with a configuration that can be used.

FIG. 4 is a functional block diagram showing a detailed configuration of the functions of the control means, for example, the computer 302 shown in FIG. The indicator control unit 401, the cursor control unit 402, and the canvas control unit 403 illustrated in FIG. 4 can be configured by software, and specifically, an RA that stores a program and can be used as a work area.
M, a memory such as a ROM, a CPU for executing arithmetic processing, and other storage means such as a hard disk.

The canvas control unit 403 executes a process for displaying the above-described canvas 102 on the display 303. The cursor control unit 402 displays the cursor 101 on the display 303 according to the position information obtained from the pointing device 301. The cursor control unit 402 writes the line drawn by the cursor 101 on the canvas 102 displayed on the display under the control of the canvas control unit 403 while the user presses the button of the pointing device 301.

The detailed configuration of the indicator control unit 401 will be further described with reference to the block diagram of FIG. The indicator control unit 401 has three control functions of a cursor adjustment unit 501, an indicator display control unit 502, and a display state control unit 503 inside. The indicator display control unit 502 displays the indicator 105 according to the position and size of the cursor 101 obtained from the cursor control unit 402 on the display 303. That is, the indicator 105 is displayed with the cursor position adjusted to the indicator control unit having the same width as the current cursor size. The display state control unit 503 determines whether or not the cursor 101 is inside the box area 104, and according to the result, the indicator 10 that the indicator display control unit 502 performs.
5 is displayed or not displayed. Cursor adjuster 50
1 indicates that the cursor 101 is displayed while the indicator 105 is being displayed and the button of the pointing device 301 is being pressed.
The amount of change in size proportional to the amount of movement of the cursor 101 is calculated, and the size of the cursor 101 is adjusted.

Further, the operation procedure of the indicator control unit 401 will be described with reference to the flowchart of FIG. FIG. 6A shows the initialization processing, and FIG. 6B shows the cursor size adjustment processing after the completion of the initialization processing. In the initialization process, the display state control unit 503 creates and displays the box area 104 (S610). The box area 104
As shown in FIG. 7, (box _left , box _bottom , box
x _right , box _top ). The indicator display control unit 502 creates the indicator 105 and makes it non-display state (S62).
0). When the initialization is completed, the system enters a standby state (S630) until the next event occurs.

After the standby state, the processing is executed according to the cursor size adjustment processing flow shown in FIG. A change in the state of the pointing device 301 is detected (S601).
Then, a conditional branch process (S602 to S604) is executed. The detection of a change in the state of the pointing device 301 in step S601 is an event detection process such as movement of the pointing device, pressing of a button of the pointing device, and the like, and is a process of detecting that some operation has been performed on the pointing device.

The meanings of the three conditional branch processes of S602 to S604 are as follows. "Basically, cursor 1
If 01 is inside the box area 104, the indicator 105 is displayed, and if it is outside, it is hidden. However, as an exception process, the cursor 101 is temporarily moved to the box area 10.
In the case where the button continues to be pressed even if the button protrudes from the inside to the outside of the indicator 4, the indicator 105
Continue to display. Such a process is performed because the cursor 101 protrudes outside the box area 104 while the user is adjusting the size of the cursor 101, so that the operation of adjusting the size of the cursor 101 is interrupted. This is to prevent that.

First, in step S 602,
It is determined whether the indicator 105 is displayed.
That is, it is determined whether or not the indicator 105 was in the display state before the new event of the pointing device occurred. If Yes, step S
The process proceeds to 603, and if No, the process proceeds to step S604.
In step S603, it is determined whether the button of the pointing device is in a pressed state. When it is in the pressed state, the process proceeds to step S605, and when it is No, the process proceeds to step S604.

In step S604, the current position of the cursor 101 is determined. That is, if the cursor 101 is within the box area 104, the process proceeds to step S605, and if No, the process proceeds to step S609. When the process proceeds to step 609, non-display of the indicator 105 is determined, and the indicator 105 is non-displayed (S609) to enter a standby state (S630).

The processing after step S605 is a step in which the indicator 105 is displayed and the cursor thickness updating processing is effectively executed. Step S605
Then, it is determined whether or not the button of the pointing device is in a pressed state. When it is in the pressed state, the process proceeds to step S606, and when it is No, the process proceeds to step S607. In step S606, the pointing device 3
The thickness of the cursor 101 is updated as a process while the button 01 is being pressed. That is, according to the position of the cursor 101 on the indicator 105, the thickness of the cursor is updated to the thickness corresponding to the height of the indicator. Next, the shape of the indicator 105 is converted into the coordinate system of the cursor 101 (S607), and the indicator 105 is displayed (S607).
608). Thereafter, the process enters a standby state (S630), and waits for the occurrence of a new event of the pointing device.

Next, the cursor 101 and the indicator 10
5 and a method of adjusting the size of the cursor 101 will be described.

As shown in FIG. 8A, the cursor 101
Is represented by a circle whose center is (x _cursor , y _cursor ) and whose radius is r _cursor . The center (x _cursor , y _cursor ) is a coordinate given by the pointing device 301. The radius: r _cursor is the size of the cursor stored in the cursor control unit 402.

On the other hand, FIG.
This is a representation of the shape. Indicator 105
Changes the height (y) of the cursor 101 in the x-axis direction using the maximum value: size _max and the minimum value: size _min and the rate of change of the cursor size with respect to the amount of movement of the cursor: pitch as parameters. Indicated by the shape area. In the indicator shape shown in FIG. 8B, the x coordinate value of the left end in the coordinate system of the indicator 105 is (size _min / pitch), and the x coordinate value of the right end is (size _max / pitch). The association of the coordinate system of the indicator 105 with the coordinate system of the cursor 101 is performed by the following equation.

[0051]

(Equation 1)

According to this equation, the cursor 101 and the indicator 105 are displayed so as to overlap each other as shown in FIG. In the above equation, x ′, y ′, z ′ are a coordinate system of the indicator 105 where the end of the indicator 105 is (0, 0, 0). Note that the above expression shows a three-dimensional coordinate system correspondence expression as a more general expression. However, in the case of two-dimensional graphic drawing, the z-axis direction correspondence is unnecessary. .

FIGS. 9A and 9B show the state before and after the movement of the cursor 101 whose size is changed. The cursor 101 is (x _cursor ,
y _cursor ) to (x _cursor + dx _cursor , y _cursor + d
y _cursor ), the size of the cursor 101 becomes r
_{The cursor} changes from r _{cursor to} dr _cursor . The relationship between the movement amount and the size change amount is expressed by the following equation.

[0054]

## EQU2 ## dr _cursor = dx _cursor × pitch

For the indicator 105, as described above, the maximum value of the size of the cursor 101: siz
e _max and the minimum value: size _min , and the rate of change of the size with respect to the amount of movement of the cursor: a shape area whose height (y) is changed in the x-axis direction using pitch as a parameter. By doing so, various shapes of indicators can be generated. For example, x
Various indicators having different rates of change in cursor size according to the amount of movement of the cursor 101 in the axial direction can be generated as shown in FIGS.

Further, the indicators are shown in FIGS.
The indicator is not limited to the one represented by a linear region as shown in FIG. 10C, but may be a circular indicator 1 as shown in FIG.
001 is also possible. In this example, the size is changed by moving the cursor 101 like an arrow according to a circular indicator. In such an indicator having a special shape, a correspondence different from the above-described indicator having a constant linear pitch, that is, a correspondence relationship of coordinates according to the indicator shape is newly defined, so that the indicator of the indicator accompanying the movement of the cursor is newly defined. The processing for changing the cursor size corresponding to the width can be executed, and the same effect as that of the above-described indicator having a constant linear pitch can be obtained.

As shown in FIG. 10 (e), as an indicator for changing the density or color as a drawing parameter set on the cursor, an indicator 1002 defining the density or color as a continuous display mode change area. Is also possible. By using an indicator configuration having a continuous density or color change depending on the position of the indicator, the density or color of the cursor can be changed based on the positional relationship between the indicator and the cursor instead of the process of changing the cursor size. In this case, instead of the pitch used as a parameter for changing the cursor size, the parameter is a density value,
Alternatively, a process of setting a change rate of a color value, for example, an RGB value in association with the indicator coordinate value, and setting the RGB color of the indicator coordinate value in the cursor based on the cursor position data is executed. With this configuration, it is possible to continuously change the density or color of the cursor by moving the cursor along the indicator.

Further, the processing parameters associated with the cursor according to the present invention can be associated not only with the drawing parameters but also with the deformation processing parameters in the CG graphic device. For example, 3D displayed on the display
Applying the user interface of the present invention to a 3D graphic processing system that executes deformation of an object by various deformation tools associated with a cursor, and sets, as a parameter, the degree of deformation processing of the various deformation tools associated with the cursor; By associating the indicator with the deformation parameter, it is possible to set a deformation processing parameter that is visually understandable to the user.

That is, the change area of the continuous display mode of the indicator is set as the continuous change area of the deformation processing parameter of the deformation tool set corresponding to the cursor, and the cursor adjusting unit is set to the continuous change area of the indicator. In accordance with the movement of the cursor along the area, the processing for updating the deformation processing parameters set for the cursor to the parameters corresponding to each area of the continuously changing area of the indicator is executed, thereby changing the degree of deformation. A user interface that allows the user to easily execute the operation is realized.

FIGS. 11, 12 and 13 show the cursor 10
FIG. 3 is a diagram for explaining an example of use and effects of 1, an indicator 105, and a box area 104. In each of the figures, the time t described in each figure represents the passage of time.

In FIG. 11, the pointing device 30
This shows a state where the cursor 101 passes through the box area 104 according to the trajectory 1101 without pressing the first button. When the cursor 101 enters the inside of the box area 104 (t = 2), the indicator 10
5 appears. Thereafter, until time t = 7, the cursor 101 moves along the trajectory 1101 without changing its size and its positional relationship with the indicator 105. At time t = 8, at the same time when the cursor 101 moves out of the box area 104, the indicator 105 is not displayed.

That is, this FIG.
5 indicates to the user that the mode for changing the size of the cursor 101 has been entered, and at the same time the cursor 1
This shows one effect of the user interface control device of the present invention that allows the user to visually understand in advance in which direction and how much to move 01 and how much the size changes.

In FIG. 12, the pointing device 30
The state of the cursor 101 and the indicator 105 when the cursor 101 inside the box area 104 is moved to the right while the button 1 is pressed is shown. As the cursor 101 moves from time t = 1 to t = 4, its size increases in accordance with the height of the indicator 105. On the other hand, the position of the indicator 105 has not moved. When the user looks at this situation, it appears that the size of the cursor 101 changes along the shape of the indicator 105. From time t = 5 to t = 8, the size of the cursor 101 is the maximum value, so that the size of the cursor 101 does not change even if the cursor 101 moves rightward. Cursor 1 because the size does not change
The positional relationship between 01 and the indicator 105 does not change. Therefore, when the user sees this situation, the indicator 1
05 cannot change the size of the cursor 101 and appears to be dragging and moving.

Similarly, FIG. 13 shows the cursor 101 in FIG.
This shows that instead of moving to the right, it was moved to the left. From time t = 1 to t = 4, the cursor 101 becomes smaller as time elapses. Further, from time t = 5 to t = 8, the size of the cursor 101 keeps the minimum value, and the indicator 105 is dragged to the left. That is, FIGS. 12 and 13 show that the shape of the indicator 105 visually indicates a change in size due to the movement of the cursor 101.

Further, in FIG. 13, although the cursor 101 after t = 3 protrudes outside the box area 104, since the button is continuously pressed, the mode for changing the size of the cursor 101 and the indicator are displayed. 10
The display of 5 is continued. By doing so, the current mode desired by the user is continued even if the cursor 101 temporarily goes out of the box area 104 by mistake during operation.

The present invention has been described in detail with reference to the specific embodiments. However, it is obvious that those skilled in the art can modify or substitute the embodiment without departing from the spirit of the present invention. That is, the present invention has been disclosed by way of example, and should not be construed as limiting.
