DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selection response display method for a display screen when an arbitrary selection area is selected on a display screen of a display device by touching or using a pointing device such as a mouse.

[0002]

2. Description of the Related Art Conventionally, in a display device 3 such as a color CRT display device having a pointing device, an arbitrary selection area is stored in a storage unit in the form of coordinates in a display unit as shown in FIG. (Fig. 6
7a). When a certain screen is displayed in FIG. 6 and the coordinate range (x ₁ , y ₁ ), (x ₂ , y ₂ ) of the selection area C is selected by the pointing device, the selected coordinates are displayed as shown in FIG. The selection area corresponding to the range is displayed with a response in a display color held on the display device side or a display color uniquely determined by the system, and an individual program runs based on the selection area C to execute a specific process. I was going.

[0003] In other words, a flowchart described in FIG. 7 which is started by a timer interrupt will be described.
At 21, it is determined whether or not the selected area of the display screen has been selected by touch or a pointing device such as a mouse. If not, the process returns to the main program. If the selection area C has been selected, the process proceeds to step S22, where the display area has the selected area or a display color uniquely determined by the system. A response is displayed in one specific color or the like, and then a specific process for each selected area is executed in step S23, and the process returns to the main program.

[0004]

However, in the above prior art, since the response display of the selection area is limited to one kind of specific color, a plurality of selection areas exist on one screen of the display device. In addition, when some of the selected areas are selected and displayed simultaneously, or when each of the selected areas performs a different function, it is necessary to instantaneously determine which function is to be performed in a certain selected area. However, there is an unsolved problem that when the device is used by an unspecified number of operators, an operation error is likely to occur.

[0005] For this reason, conventionally, identifiable pictures and characters are displayed on a screen corresponding to a selected area, and when a specific operator is used exclusively, education and training for the operator are performed. It is conceivable, however, that in the former case, the creation of a display program becomes complicated, and in the latter case, a training period for a specific operator is required, and the use of an unspecified number of operators is limited.

Accordingly, the present invention has been made in view of the above-mentioned conventional unsolved problems, and makes it easy to create a program and reduces the risk of operation errors even when an unspecified number of operators use the program. An object of the present invention is to provide a selection response display method for a display screen.

[0007]

In order to achieve the above object, according to the present invention, there is provided a response display method of a display screen, wherein an arbitrary selection area is selected by a pointing device on a display screen of a display device. In the response display method, which displays a response on a screen corresponding to the above, storage for storing a display color for each function in correspondence with the coordinates of each selection area displayed on the display screen for each display screen of the display device Means and display color determining means for determining a corresponding display color by referring to the storage means based on the coordinates of the selected area when a selection area is selected by a pointing device on an arbitrary display screen. And displaying a response on the display screen in the display color determined by the display color determination means.

[0008]

According to the present invention, when a selection area is selected by a pointing device on an arbitrary display screen, for example, a display color for each function is stored in advance in the storage means in association with each area coordinate. In addition, a response is displayed on the display screen in a function-specific display color that is paired with the coordinates of the selection area, so that the quality of the selection can be visually recognized intuitively.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing one embodiment of the present invention. In FIG. 1, 1 is a display device,
The display includes a color CRT display 2 as a display device, a display screen 3 of the color CRT display 2, a touch detection device 4 in which an infrared light emitting unit and a light receiving unit are arranged on the display screen 3 in XY directions, and a control unit 5.

The control unit 5 includes a CPU 6 for controlling the entire display device 1, a storage unit 7 for storing programs and data, a display control unit 8 including a video memory, a video memory controller, and an interface, and a touch detection device 4. And a touch input unit 9 for receiving touch coordinates from the CPU 6 and transferring the touch coordinates to the CPU 6, and a bus 10 is connected between these units.

In the storage unit 7, a selection area information storage area is formed. As shown in FIG. 2, the storage area is a lower left and upper right for each selection area displayed on the display screen 3 of the color CRT display 2. Has a data structure in which a pair of XY coordinate storage units and a display color storage unit for storing a response display color when a range surrounded by the XY coordinates is selected are formed in a continuous area. That is, an arbitrary selection area is stored in the storage unit 7 in a coordinated manner and a response display color in pairs for each displayed screen.

The CPU 6 searches whether or not the touch coordinates detected by the touch detection device 4 exist within the range of the coordinates stored in the selection area information storage area of the storage unit 7. _{x 11, y 11), (} x 12, y 12)
If the CPU 6 determines that the value is within the range, the image is displayed on the display screen 3 in a response display color based on the color code of the selection area A stored in an area continuous with the XY coordinate storage section of the selection area A.

Next, the operation of the above embodiment will be described with reference to the flowchart of FIG. This flowchart is started by a timer interruption. First, step S1
Then, it is determined from the state signal from the touch detection device 4 whether or not the display screen 3 has been touched. If there is no touch, the process returns to the main program. If a touch has been made, the process proceeds to step S2, where it is determined whether or not the previous touch input process has been completed. If not, the process directly returns to the main program. If completed, the process proceeds to step S3, and it is determined whether or not the coordinates of the touch input are within the range of the selection area A. If it is within the range of the selection area A, the process proceeds to step S4, and the coordinate range of the selection area A is changed to a predetermined response display color (for example, green) representing the function of the selection area A, as shown in FIG. Is displayed on the display screen 3 as a response. Next, in step S5, it is determined whether or not the confirmation / cancellation state signal by the touch of the operator has been set. If set, the process proceeds to step S6 to determine whether the confirmation / cancellation state signal is in the confirmation state. If the cancellation state signal has been set, the process proceeds to step S7 to select the selected area A
Is returned to the main program with the response display of no. If the confirmation state signal has been set in step S6, the process proceeds to step 8, switches the display to another screen, executes a predetermined process in step S9, and returns to the main program.

If the coordinates of the touch input are out of the range of the selection area A in step S3, the process proceeds to step S10, and it is determined whether the coordinates of the touch input are in the range of the selection area B. If the selected area is not within the range of the selected area B, the process returns to the main program as if the touch area other than the selected area defined on the display screen 3 was touched. If it is within the range of the selection area B, the process proceeds to step S11, and the coordinate range of the selection area B is changed to a predetermined response display color (for example, blue) representing the function of the selection area B and confirmation / cancellation as shown in FIG. Is displayed on the display screen 3 as a response. Next, in step S12, it is determined whether or not the confirmation / cancellation state signal by the touch of the operator has been set. If not, the process waits for setting in step S12.
If it is set, the flow goes to step S13 to determine whether the confirmation / cancellation state signal is in the confirmation state. If the cancellation state signal is set, the flow goes to step S7 to display the response display of the selection area B. Return to the main program with no display. If the confirmation state signal has been set in step S13, the process proceeds to step S14, where the data input area is displayed, and a predetermined process is executed in step S15.
Return to the main program.

Here, the selected area information storage area of the storage unit 7 corresponds to the storage means, and the steps S3, S4 and S1
0 and S11 correspond to display color determining means. Therefore,
Now, it is assumed that a selection area A and a selection area B having different functions are displayed on the display screen 3 as shown in FIG. 3 when the program is started by a timer interruption.
That is, the selection area A has the coordinates (x _{11,
y 1 1), (x 12} , if the range of y ₁₂₎ is selected by a touch, and switching display to another screen, the selection area B,
Coordinates of the area (x _21, y _21), in the range of (x _22, y ₂₂₎ when selected by a touch, the area for displaying the data input area. In this case, the storage unit 7 previously stores the coordinates (x _11, y ₁₁ ), (x ₁₂ ,
y ₁₂ ) and the code of the response display color of green corresponding to the screen switching function at that time and the coordinates (x
_21, y _21), and stored in the selection area information storage area as (x _22, y ₂₂₎ a pair of code responses display color of the example, blue corresponds to the data input function of time.

Then, when the processing of FIG. 5 is executed,
If there is no touch input, the process returns from step S1 to the main program. On the other hand, when the operator touches the selection area A, it is determined in step S1 that a touch input has been made, and in step S3 it is determined that the touch is within the range of the selection area A. Therefore, as shown in FIG. In S4, the selection area A is displayed in the green response display color stored in the storage unit together with the coordinates of the selection area A.
Is displayed as a response. Therefore, the operator can intuitively determine whether the user has touched the intended area normally or erroneously by using the display color for each function.
When the selection is correct, the operator touches the confirmation area shown in FIG. 4, so that a confirmation state signal is input in step S5, and in step S8, a display is displayed on another screen corresponding to the selection area A as shown in FIG. Switch.

Next, when the operator touches the selection area B, it is determined in step S1 that a touch input has been made, and in step S3 it is determined that the touch is not within the range of the selection area A, and the process proceeds to step S10. In step S10, it is determined whether or not the touch is within the range of the selection area B. If the selection is correct, the operator touches the confirmation area shown in FIG. 4, so that a confirmation state signal is input in step S12, Step S14
Then, a data input area corresponding to the selection area B is displayed on the display screen 3 as shown in FIG. If it is determined that it is not within the range of the selection area B, the operator returns to the main program as it is as if the operator touched the display screen 3 by mistake.

Next, when the selection area A is erroneously touched where the selection area A is to be touched, or when the selection area A is erroneously touched where the selection area B is to be touched, the operator Intuitively determines an error with the display color for each function and touches the cancellation area shown in FIG. 4, so that a cancellation state signal is input in step S5 (or step S12), and in step S7, the selection area B is selected.
The display of the response to (or the selection area A) is not displayed, and the process returns to the main program. Therefore, the operator can touch the display screen 3 again.

Therefore, according to the above-described embodiment, the response display colors stored in the storage unit in correspondence with the coordinates of an arbitrary selection area can be set to be different display colors for respective functions on a display screen basis. By recognizing the color, it is possible to intuitively judge whether or not there is an erroneous operation. Even if the selection area displayed on the display screen 3 is divided by the distinction of the processing function or the distinction of the importance, the response display color is displayed. By performing function classification by color and ranking of importance by color, the operator can easily determine and reduce erroneous operations.

In the above embodiment, the selection areas are exemplified by A and B. However, the present invention is not limited to this, and a required number of combinations of the selection area coordinates and the response display colors are stored in the storage unit 7.
Can be stored in the selected area information storage area. In the above embodiment, when a plurality of selection areas can be simultaneously specified on one display screen, a different response display color for each selection area is stored in the selection area information storage area of the storage unit 7. Thus, the display color may be changed for each selected area.

Further, in the above-described embodiment, the touch detection device 4 is used as the pointing device. However, the present invention is not limited to this, and a pointing device such as a mouse, a light pen, and a digitizer may be used. Furthermore, in the above-described embodiment, the control unit 5 can be connected to a higher-level control device via an input / output interface (not shown).

In the above embodiment, the color CRT
Although the display 2 is used, the present invention is not limited to this, and another display device such as a color liquid crystal display device may be used.

[0023]

As described above, according to the selection response display method of the display screen according to the present invention, the coordinates of the selection area and the response display color are stored in pairs in the storage means.
When a selection area is selected by a pointing device on an arbitrary display screen, the display color determining means can display a response on the display screen in a display color corresponding to the coordinates of the selection area. Only the function of creating data in the storage means and reading and displaying the display colors corresponding to the coordinates may be added, and there is an effect that the creation of the program is easy.

In addition, even if a large number of unspecified operators are used, it is possible to intuitively judge whether or not the intended selection area has been selected by the display color for each function on the display screen. The effect is that the performance can be greatly improved.
