Abstract

PURPOSE:To perform convenient graphic selection by deciding the selection order of each graphic element in a graphic element group, making one or more graphic elements correspond to one position information, and selecting the graphic element in sequence decided in advance by a selection instruction from a user. CONSTITUTION:A position element input processing program 41, a correspondence processing program 42 for position element and graphic element, and a graphic element selection confirmation processing program 43 exist in a memory 40, and furthermore, the graphic element groups 44 are stored in decided sequence. At the time of selecting a specific graphic element out of displayed graphic element groups, the user designates first only a position in the neighborhood of a corresponding graphic element. When plural graphic elements which satisfy a condition included in the position exist, a first graphic element is selected and displayed first to the user, and when it is not a targeted one, a second graphic element is selected and displayed to the user. Such operation is repeated until the targeted graphic element can be obtained. In such a way, it is possible to perform the final decision of the graphic element after a position element is designated directly by the user, and to select a desired graphic.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for selecting a specific graphical element from a group of graphical elements displayed on a display device of a computer system.
Graphical element selection method particularly suitable when graphical elements are close to each other or overlap each other in a complicated manner [Prior art] Conventionally, one graphical element is selected from a group of graphical elements displayed on a display device of a computer system.

This method uses the keyboard or mouse to specify the positions corresponding to the desired graphic elements one by one. In addition,
Position designation includes one-point designation, in which one graphic element is associated with one location element, and multiple-point designation, in which one graphic element is associated with several location elements.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not give sufficient consideration to the individual will and individual differences of the user, and the user's will is reflected only in the designation of the positional element, and the response after the designation is It is decided regardless of the user's will,
The user's mapping ability (ability to select graphical elements) is not fully utilized. Therefore, even for boat fishing users, the only way to improve operability is to complicate the correspondence logic between positional elements and graphical elements, and the performance (correspondence processing speed)
There is a high possibility that this will lead to a decrease in Furthermore, when a plurality of graphical elements overlap at the same position, depending on the quality of the logic, unexpected graphical elements may be selected, or certain graphical elements may not be selected.

An object of the present invention is to solve the above-mentioned conventional problems, fully utilize the user's flexible shape selection ability, and be able to select a desired graphic element in a short time without fail, thereby realizing more convenient shape selection. It's about doing.

[Means to solve the problem]

In order to achieve the above object, the present invention predetermines the selection order of each graphical element of a graphical element group, makes one or more graphical elements correspond to one piece of positional information, and The present invention is characterized in that when a user instructs selection of one or more graphic elements, the graphic elements are selected in the predetermined order.

[For production]

When selecting a particular graphical element from a group of graphical elements displayed on a display device, the user first simply specifies a position in the vicinity of the graphical element. If there are multiple graphical elements that satisfy the conditions included in this position, the first graphical element among them is selected and shown to the user. When a response is returned from the user that this graphical element is the desired one, the selection process ends at step 5. If it is not the purpose, then 1st and 2nd
Select the th graphical element and show it to the user. This process is repeated until the desired graphic element is obtained. The graphic elements can be selected in a predetermined order, and no complicated logic is required. Furthermore, since the final selection of graphical elements is directly determined by the user, there is no possibility that a certain graphical element cannot be selected, or that an element that is contrary to the user's wishes is selected.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of a computer system targeted by the present invention. This computer system has keyboard 1
0, central processing unit ff (CPU) 20, display device 30
and memory 40. On the memory 10, as processing programs related to the present invention, there are a positional element input processing program 41, a processing program 42 for associating positional elements and graphical elements, and a graphical element selection confirmation processing program 43.
Further, graphic element groups 44 are stored in a predetermined order.

Graphical element data consists of positional information (positional element) and graphical elements, and a plurality of graphical elements are allowed to correspond to one positional information.

FIG. 2 shows an example of the procedure of graphic element selection processing according to the present invention, which is executed by the CPU 20 under the control of programs 41 to 43 in the memory 40.

Assume that a group of graphical elements is displayed on the display device 30. When the user specifies the vicinity of a graphical element to be selected using the keyboard 10 or mouse while viewing the display screen of the display device 30, positional information of one point is input as the cursor position (step 101). By inputting this positional information, a graphical element associated with the positional information is selected from the graphical element group 44 in the memory 40, and the graphical element is displayed in a different color (step 102).

At this time, if there are multiple graphic elements that meet the conditions included in the range for the specified cursor position,
The first one (for example, the lowest memory address) is selected, and only that graphic element is displayed in a different color.

Next, a guidance message is displayed on the display device 30 asking whether the graphic element currently displayed with a different color is acceptable.
Waiting for a response from the user (step 103) a The user inputs a figure selection response from the keyboard 10. User responses include rYESJ, rNEXTJ, and rBACKJ. If r Y l': S J, it is determined that the graphic element currently displayed in a different color is sufficient, and the graphic element selection process is ended (step 104). In the case of rNEXTJ, the next graphical element (for example, the one next to the memory address) of the graphical element currently displayed in a different color among the graphical elements that satisfy the conditions included in the range of the cursor position.
is selected (Step 1.05), and the graphic element is displayed in a different color (Step 06).

In the case of rBACKJ, select the graphic element (for example, the one before the memory address) before the graphic element currently displayed in a different color (step 107), and display that graphic element in a different color. (step 108). Note that in steps 106 and 108, the graphic elements that were displayed in different colors are returned to their original colors.

After step 106 or 108, a guidance message for graphic element selection is displayed again and a response from the user is awaited (step 103). At 2\, the user selects rYES.
If the response is J, the process will end (step 104), rN
For EXTJ or rBAcKJ, repeat step 1
05, 106 or steps 107, 108 are repeated. Also, if users rYEsJ, rNEXTJ, r
If there is no response to BACKJ and a new cursor position is specified, the process will start over from step lot.

In this example, the number of graphical elements that the user has to select becomes too large, and the operability deteriorates.
This problem is avoided by providing means for selecting the previous graphic element and the next graphic element.

In the embodiment, the selected graphic element is displayed in a different color, but this may be done by other methods such as blinking.

FIG. 3 shows a specific example of a combination of graphical elements targeted by the present invention. (a) is an example in which the areas of the rectangle 201, the halftone 202, and the character string 203 completely match. In (b), 205 to 208 are all straight lines, and 204
(c) is an example in which the straight line 209 and the point 209' completely match each side in position and length. In such cases, conventionally, it is impossible or very difficult to select one graphic element, and it is necessary to take supplementary information such as the type of graphic element into consideration, or to select elements at the same position by taking into account the vertical relationship. In this case, by selecting only the graphical elements in ``2'', it was barely possible to select them. In contrast, the present invention does not require such complicated processing at all, and the user only needs to first specify the cursor position near these graphical elements, and the rest is "
A desired graphical element can be selected by simply specifying "YES", rBACKJ, rBACKJ, etc.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since the user can directly make the final decision on the graphical element after specifying the positional element, there are the following effects.

(1) Even if a plurality of graphic elements exist at the same position, the desired graphic can be selected without fail.

(2) For example, when selecting the center of five parallel straight lines, in the conventional method it was necessary to specify the position element accurately, but with the method of the present invention, A desired graphic element can be selected even if the error in specifying the positional element is large to some extent.

(3) Although the correspondence between positional elements and graphical elements is logically simple, each graphical element can be selected without fail. Therefore, mapping using a computer can simplify and speed up the processing.
