Abstract

PURPOSE:To enable an operator to visually easily understand command names and contents of command processings by encoding and displaying executed command processing contents. CONSTITUTION:The operator inputs commands and command parameters to a computer 4 by input devices such as a mouse device 2 and a keyboard device 3. The computer 4 calculates command names, processing contents, and processing object graphics in accordance with command history information of indicated commands and encodes processing object graphics, command processing contents, and correspondence relations between them and displays them on a display device 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a guidance display method in a computer interaction system, and relates to a guidance display suitable for making it easier for an operator to understand the contents of executed command processing. .

[Conventional technology]

Guidance displays in conventional dialogue systems include the name of the command entered when inputting a command, what parameters the command requires next, the values of the parameters entered, and the command input information entered so far. There was one that displayed ``as a string guidance''. Also, when canceling a command,
The last executed command process was targeted, and the target of the cancellation process was not clearly displayed to the operator. This type of prior art includes the rHITAC programming support editor ASPEN User's Guide Nor-92 and the like.

[Problem to be solved by the invention 3: When an operator wants to know the commands executed in the past, it is necessary to read the necessary information from the command history displayed as a character string, which takes time to understand. When the number of command types increases, it is easy to confuse the command type because there are similar command names and the number of characters in the command name becomes long. In addition, the relationship between a command and the shape created by that command must be interpreted by the operator based on the parameters of the displayed command, and it is difficult even for the last command executed, especially for past commands and commands. This is very difficult if the history is not displayed. Further, when canceling a command, there is a problem in that it is easy to make a mistake in determining which figure is affected by the canceling process, resulting in unnecessary canceling process, resulting in poor operability.

[Means to solve the problem]

The purpose of the above is that when an operator wants to know the contents of an executed command, he instructs the computer to execute that command, and the computer system determines the command name, processing contents, and figure to be processed from the command history information of the instructed command. This is accomplished by calculating and symbolizing and displaying the processing target graphic, command processing contents, and their correspondence.

[Effect]

Since the processing details of the command are displayed as symbols, the command name and the details of the command processing can be easily understood visually. Furthermore, since the correspondence between the graphics to be processed and the commands is also displayed, it is easy to identify the graphics to be processed.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the configuration of the device of this embodiment, where l is a graphic display that is a display device for displaying graphic information, 2 is a mouse device, 3 is a keyboard device, and 4 is a graphic creation and modification device. This is a computer that controls 2-display. The operator inputs commands and command parameters to the calculator 4 using input devices such as 2 and 3,
The process of determining the processing result displayed on the graphic display 1 from the computer 4 and inputting the command again is repeated until the desired result is obtained.

FIG. 2 shows a mouse device 2. 3 is a diagram showing an example of a display screen of a graphic display l for explaining input of commands and command parameters using the keyboard device 3. FIG. To input a command, on the mouse device 2, place the cursor 6 moved by the mouse 2 inside one of the command boxes 7 of the menu 5 displayed on the graphic display and press the button provided on the mouse 2. This can also be done by typing the name of the command on the keyboard 3.

The command name is displayed in the command box 7. Command parameters can be entered by moving the cursor 6 to the required position on the display screen of the graphic display 1 using the keyboard 3 for character strings or numbers, or using the mouse 2 for coordinate values, according to the input instruction display from the calculator 4. The user presses a button on the mouse 2 or presses a set of X coordinate/Y coordinate values on the keyboard 3. In this example, ten commands are set in command box 7. FIG. 3 shows the command functions and parameters set in the command box 7.

Each selected figure is moved (copied) according to the vector created by the coordinates. The guide command displays the content of the command as guidance based on the command number in the command history. if the parameter is omitted.

Display guidance on the contents of the last executed command. The hist command displays a list of commands executed so far from the top left of the screen. Each command displayed also includes the serial number from when the system was first used.

In FIG. 4, 0 figures 8, 9, and 10 are displayed, which is the display state immediately after the figure has been moved, and figure 8 is the moved figure. Here, in order to know the processing contents of a command, when the guide command is executed for the immediately preceding command, the command processing contents are displayed in a symbolic form as shown in FIG. Here, since the immediately preceding command is the rmove command, the arrow figure 11, the character '1sIj13 indicating the reference coordinate point of movement, the letter "d" 14 indicating the destination coordinate point, and the figure 12 before movement are displayed as dotted lines. The moved figure will be displayed with high brightness. Arrow shape.

This represents a move command, and the arrow figure is displayed so that both ends thereof coincide with the reference point of the moved figure. Therefore, the length of the arrow figure represents the moving distance, and together with the figure before movement displayed as a dotted line, the processing content of the movement command can be expressed. The letters S and d indicate the coordinate positions of the input parameters of the @ova command. In this example, there is one figure to be moved, but if there are two figures, the arrow figure and the figure before movement are equal to the number of figures to be moved, that is, two figures, as shown in Figure 5.
will be displayed. The same applies when there are two or more target figures.

Furthermore, since the letters S and d are input for a movement command, a pair of letters S and d are displayed. Even if the immediately preceding command is a command other than the move command, it will be displayed in the same manner as shown in FIG. For the (1) rect and (2) poly commands, the created figure is displayed as a dotted line, and characters p1...pn representing the input point and a figure representing the command are displayed near the input point coordinate position.

In the processing of the 1ayer command in FIG. 9(d), the drawing layer temperature is obtained from the command history in step 71, and step 72
Displays eyebrows and a figure representing the 1ayer command in the center of the display screen. The command history records information shown in FIG. 10 for each command. The first information is a command number, which is assigned in order starting from 1 for each command operation from the time the system is started. The second is the command name and input parameters, the third is a list of figure numbers of the figures to be processed, and the fourth is the figure information of the processing result. The graphic information of the processing result is composed of a graphic type and a vertex coordinate string of the graphic. For a rectangle, the graphic type +1 R11, the lower left and upper right coordinates as the vertex coordinate string, and for a polygon, the graphic type is 11 P 19. As a vertex coordinate string, polygonal vertex coordinate strings are recorded in the input order. The order of the graphic information corresponds to the graphic number list. Fifth, the figure number of the figure created by the process is recorded. Information after the third command may not be available depending on the command. If you need the figure information before processing with the move command, etc., use the move, copy command that targets the same figure number.
, rect.

Search for any of the poly commands,
The graphic information of the processing result of the first searched command is used.

In the example described above, only guidance regarding the command content and the shape before and after the command is processed is displayed, but if the shape has been processed multiple times since it was created, such processing will be displayed. The contents may also be displayed as guidance at the same time, in which case the processing contents for the figure will be easier to understand.
There is.

Guidance for the first movement command is displayed. In addition to the arrow 11 representing the first move command, an arrow 16 representing the next move command is displayed as a dotted line, indicating that the rectangle 15 has undergone two consecutive movement processes from position 12 to position 8. . Furthermore, since there is a figure representing the rect command in the rectangle at position 12, it can be seen that the maove command, which is the guidance target, is the first movement process of the rectangle generator. In addition, guidance other than these commands of interest can be displayed only before or after the command of interest, or
The display of guidance for one or more related commands may be controlled based on instructions from the operator.

Furthermore, a graphic representing a command may be displayed as a moving image.

Furthermore, the target figure for command processing may be displayed in a different color from that of the normal figure or blinking, instead of being displayed as a dotted line or with high brightness. Further, the command for displaying the guidance may be issued by specifying a displayed figure instead of by inputting a command number as in the above embodiment. In the case of a graphic instruction, guidance for a command in the command history having that graphic number may be displayed from the graphic number of the instruction graphic.

As described above, according to this method, the contents of the executed command are displayed in a symbolic form, making it easy for the operator to understand the contents of the command and also making it easy to identify the figure that is the target of the command processing. becomes.

Next, a command usage display method using the above method will be described.

The help function, which explains the command functions of the system to operators with little experience in using computer systems while the system is running, is used in many systems because it improves operability and simplifies training for beginners. There is. but,
All explanations are character strings, so even if you can understand the command function and command format, it is difficult to understand how it is actually processed.6 Especially when using a mouse or tablet.
! This becomes more of a problem when using an indicating device. Therefore,
When displaying how to use a command, guidance including an example of a command input format and an explanation as well as an example of command processing and correspondence with command parameters is displayed.

FIG. 12 is an example of a move command. An explanation of the function and parameters of this command is displayed at the bottom of the move command format example, and an example of command processing is illustrated at the top, and the correspondence between the first parameter, the next parameter, and the parameters in the movement process is illustrated. be done. By displaying the guidance in this manner, it becomes easier to understand the meaning of the parameters of the command, and even an operator with little experience can quickly understand the command. In the above example, the move command is explained, but guidance is similarly displayed for other commands. It is also conceivable to display detailed explanations of command functions and the like.

Next, a command cancellation method using the one-line method will be explained using FIGS. 13 and 14.

The command cancellation process is shown in the first screen, which shows an example of one display screen.
The processing contents of the command executed by the undo command 18 in FIG. 3 and subject to cancellation processing are displayed as in the first embodiment, and an execution confirmation message 17 is also displayed. The operation is performed by pressing the t Y l key to execute the command cancellation process, and by pressing the l N l key to not execute the command cancellation process. The command number to be canceled from the command history 19 is input into the parameter of the undo command. In Figure 13, command number 12
is input and a rectangle 20 which is an input echo is displayed in the command history, and the processing content of the move command with command number 12 is displayed as an arrow 22. Here, the figure to be processed that is to be canceled is one figure numbered 8 in FIG.
Assume that the command number 12 is canceled based on the assumption that it is in the vicinity based on the operations up to now. In this case, the first
Since there are two target figures from the arrow 22 in FIG. 3, the operator immediately knows that command number 12 is not the command to be canceled, and cancels the cancellation process.

Then, when the cancellation process for command number 8 is performed, it is found from 11 in FIG. 14 that the target figure is 8, and the cancellation process (UNDO) is executed. In this way, by checking the shape to be canceled and controlling whether or not to execute the cancellation process, there is no need to remember the command to be canceled, and the command can be retrieved from the parameter value in the command history. Since there is no need to interpret the target figure, the cancellation process can be performed with good operability. Furthermore, since the position of the figure after the cancellation process can be confirmed, it is possible to avoid performing the cancellation process by mistake. In this embodiment, the command to be canceled is indicated by the command number, but the command display line may be indicated on the command history using a mouse or the like, and the command number may be obtained from its coordinate values. Alternatively, instead of using the command number, a figure to be canceled may be specified and a related command number may be obtained from the figure number.

〔Effect of the invention〕

According to the present invention, since the content of the executed command is displayed in a symbolic form, it is possible to display guidance that makes it easy for the operator to understand the content of the command and to easily identify the figure that is the target of the command processing.
