Abstract

PROBLEM TO BE SOLVED: To make it possible to cancel only one arbitrary item after selecting arbitrary items by using only a pointing device by providing each selection item with a selection flag and setting or resetting the selection flag each time the selection item is selected with the pointing device. SOLUTION: A touch panel selection decision part 11 decides the position that an operator touches and selects on a touch panel 3. The equipment operation SW selection flag of the touched equipment operation SW is referred to among equipment operation SW selection flag parts 13 provided to respective equipment operation SWs. Then the equipment operation SW selection flag is set or reset each time a choice is made with the pointing device such as the touch panel 3. Therefore, canceling operation which uses both the touch panel 3 and a keyboard 4 before is replaced with operation by only the pointing device to improve the operability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for selecting a selection item such as a symbol and a pattern displayed on a display device by operating a pointing device.

[0002]

2. Description of the Related Art FIG. 3 is an explanatory diagram of a cancel operation after one item is selected according to the prior art. As shown in (a), a plurality of selection items are displayed on the display device. And
The pointer is moved to the position of the selected item by the pointing device as shown in (b), and the item is selected as shown in (c). When canceling the item in the selected state, an operation of pressing a “cancel” key on the keyboard is performed as shown in (d) to cancel as shown in (e). Therefore, the operator needs to change the operation from the pointing device to the keyboard.

FIG. 4 is an explanatory diagram of a cancel operation after selecting a plurality of items according to the prior art. As shown in (a), a plurality of selection items are displayed on the display device. Then, the pointer is moved to the position of the selected item by the pointing device as shown in (b), and the item is selected as shown in (c). Similarly, when a plurality of items are selected as shown in (d) to (g) and an operation of pressing a "cancel" key on the keyboard is performed as shown in (h), the selection is made as shown in (i). All items in the completed state are canceled.

[0004]

In such a conventional canceling operation, it is impossible to cancel an arbitrary one of a plurality of selected items. An object of the present invention is to use only a pointing device without changing an operation from a pointing device to a keyboard when canceling after selecting any one of a plurality of selection items displayed on a display device. The purpose is to make it possible to cancel, and to make it possible to cancel only one arbitrary item after selecting an arbitrary plurality of items.

[0005]

A selection flag is provided for each selection item displayed on the display device, and the selection flag is set and reset each time the selection item is selected by the pointing device.

[0006]

FIG. 5 is an explanatory diagram of a cancel operation after one item is selected according to the present invention. As shown in (a), a plurality of selection items are displayed on the display device. And
The pointer is moved to the position of the selected item by the pointing device as shown in (b), and the item is selected as shown in (c). If the user wants to cancel the selected item, the user can select the item with the pointer again as shown in (d) and cancel it as shown in (e).

FIG. 6 is an explanatory diagram of a cancel operation after selecting a plurality of items according to the present invention. As shown in (a), a plurality of selection items are displayed on the display device. And
The pointer is moved to the position of the selected item by the pointing device as shown in (b), and the item is selected as shown in (c). Similarly, when it is desired to cancel an arbitrary item after selecting a plurality of items as shown in (d) to (g), the item is selected again by the pointer as shown in (h), and as shown in (i). As described above, only the item is canceled, and the other selected items are kept selected without being canceled.

FIG. 1 is a block diagram showing an embodiment of the present invention.
FIG. 2 shows a flowchart thereof. It is an Example in operation of the plant component equipment used in the monitoring and operating device of various plants. In the figure, 1 is a device operation execution device, 2 is a CRT as a display device, 3 is a touch panel as a pointing device, and 4 is a keyboard. Further, the device operation execution device 1 includes a touch panel selection determination unit 11, a CRT display unit 12, a device operation SW selection flag unit 13, a keyboard selection determination unit 14, a device operation S
It comprises a W execution unit 15.

The detailed operation of such a configuration will be described with reference to FIGS. When the operator operates the touch panel 3 or the keyboard 4, the operation is determined by the touch panel selection determination unit 11 or the keyboard selection determination unit 14. When the touch panel 3 is used, the process proceeds to STEP2, and when the keyboard 4 is used, the process proceeds to STEP9 (STEP1).

The position touched by the operator on the touch panel 3 is determined by the touch panel selection determining section 11 (STEP 2). When the touched position is the device operation SW which is a selection item, the process proceeds to STEP4,
If it is not the device operation SW, the process returns to STEP 1 (STE
P3). The device operation SW selection flag of the touch-selected device operation SW is referred to from among the device operation SW selection flags 13 provided in each device operation SW, and when reset (unselected state), go to STEP5. If it is set (selected state), the operation proceeds to STEP 7 (STEP 4).

Device operation S of the device operation SW selected by touch
The flag of the W selection flag section 13 is set (selected state) (STEP 5). In order to notify the operator that the touch-selected device operation switch has been selected, the CR
The device operation SW selection frame is drawn on the CRT 2 by the T display unit 12, and the process returns to STEP 1 (STEP 6).

Device operation S of the device operation SW selected by touch
Reset the flag of the W selection flag section 13 (unselected state)
(Step 7). In order to notify the operator that the touch-selected device operation switch is in an unselected state,
The device operation SW selection frame is displayed on the CRT display unit 12 as CRT2.
And the process returns to STEP 1 (STEP 8).

The type of key selected by the operator using the keyboard 4 is determined by the keyboard selection determining unit 14 (STEP 9). When the type of the selected key is the transmission key, the process proceeds to STEP 11;
It returns to STEP1 (STEP10). Referring to the flags of the device operation SW selection flag unit 13 of all the device operation SWs displayed on the CRT 2, the device operation SW execution unit 15 is set only for the device operation SW set (selected).
To execute the device operation defined in each device operation SW, and return to STEP 1 (STEP 10).

[0014]

According to the present invention, a selection flag is provided for each selection item, and the flag is set / reset each time a selection is made with a touch panel or a pointing device such as a mouse, so that the operation of pressing the "cancel" key on the keyboard is not performed. In addition, it is possible to cancel the selected state from the pointing device, and it is also possible to cancel only one arbitrary item from the plurality of items in the selected state.

Therefore, the operability is improved by replacing the cancel operation, which conventionally uses both the pointing device and the keyboard, with only the pointing device. In addition, since any one of a plurality of items in the selected state can be canceled, a detailed selection operation can be performed.
