Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a man-machine device, and more particularly to a man-machine device that clearly indicates a target item selected on a CRT display screen.

(Prior Art) Conventionally, a keyboard has been mainly used as an input device of a man-machine using a CRT display device. However, in recent years, with the development of computer systems, the number of types has increased, and light pens, touch screens, mice, trackballs, etc. have also been used.

Therefore, if this type of man-machine input device is used as a man-machine interface of a system that performs plant operation, etc., switching of displayed screens, selection of items, numbers, etc.
It is convenient as a means to inform the computer of any position on the screen.

That is, the operator only has to touch the selected item with his / her hand or pen or move the cursor to that position and press the button attached to the device. Therefore, as with the keyboard, the display screen and the keyboard are alternated. This is because it is possible to select an item without shifting the line of sight to and to keep an eye on the display content of the screen.

Therefore, it is ergonomically very easy to use, and a superior man-machine system can be provided.

However, when the operator selects an item, etc., it is necessary to know which item displayed on the screen is the selection target and whether the action of "selected" has led to the computer. . As a means to do so, conventionally, the item to be selected on the screen is surrounded by a frame, the area and the item name are clearly displayed in different colors, or
When the action of “selected” was passed to the computer, the operator was informed by changing the color of the area or name of the item, blinking, etc., as described above.

(Problems to be Solved by the Invention) According to the above-mentioned conventional method, the item to be selected is indicated in different colors from the time of the first screen display, not when the operator is notified that “selected”. in case of,
At the time of design, sufficient consideration must be given when deciding the display color, which may give an extra constraint condition.

Further, even if it is shown by a frame, if the screen has a lot of display contents, it becomes crowded and the screen becomes difficult for the operator to see.

Also, depending on the display contents of the screen, the items to be selected may be clear even if they are not clearly shown in colors or frames, and further, as the operator becomes accustomed to driving, it may not be necessary to make them clear.

Considering all of the above things, it is very difficult to design a screen that allows you to freely decide the display color, is easy to see, and displays the information that requires the minimum operator operation. It took time and there was a problem.

The present invention has been made to solve the above problems, and aims to provide a man-machine device that eliminates extra consideration for display colors and the like during screen design and provides a neat and easy-to-see screen. There is.

[Structure of the Invention] (Means for Solving Problems) In the present invention, a screen address corresponding to a hit area is calculated from a screen of a CRT display device in which a plurality of hit areas are displayed by using a man-machine input device. When this screen address is the target of processing, when performing the data processing corresponding to this and displaying it on the screen, the hit area is surrounded by a frame or back It was constructed so that it would not be colored.

(Operation) Therefore, the hit area in the normal state is displayed on the screen without being distinguished by the display color or the like, but when the operator explicitly requests to display the hit area, the hit area is displayed as a frame or It will be clearly indicated by the background color.

(Examples) Examples will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a man-machine device according to the present invention.

In FIG. 1, 1 is a CRT display device for displaying plant data and selection items by the screen display means 2, 2 is a keyboard, 3 is hit area display request input means for requesting explicit selection items, and 4 is It is a man-machine input device such as a light pen, a touch screen, a mouse, and a trackball.

At step 51, hit points HX and HY on the display device are read, and at step 52, the screen number is read. In Step 53, the screen N is displayed by the hit area address table.
Search for o.

That is, in step 54, n = 1 is set, then in step 56, the coordinates of the starting point and the ending point (corresponding to the hit point) in each screen No. are read, and in steps 57 and 58, the read screen No. It is compared whether the hit point is included in the hit area address of.

If it is not included in any of steps 57 and 58, n = n + 1 is set in step 59, and the above operation is repeated until the end is confirmed in step 55.

In steps 57 and 58, if the hit area address of the sequentially read screen No. contains a hit point, the process proceeds to step 510 to perform a predetermined man-machine data process, and if it is not a screen change, ends.

If it is a screen change, screen N is displayed in step 512.
Change o.

Then, step 51 is implemented by the screen address input means 14, steps 52 to 59 are implemented by the input address determination means 13, step 510 is implemented by the man-machine data processing section 8, and steps 511 and 512 are implemented by the data display request means 11.

Separately from this, when the hit area display request accepting means 9 detects that the hit area display request input means 3 has made a hit area display request, it notifies the hit area display request means 10.

On the other hand, the hit area display requesting means 10 extracts the data of the hit area corresponding to the screen number notified from the data display requesting means 11 from the hit area address table 15, converts it into display data, and transfers it via the FIFO to the screen. Display means 12
Output to the CRT display device 1.

FIG. 6 is a flow chart when there is a hit area display request. A hit area display request is accepted in step 61, and the screen number is read in step 62. Step 6
In step 3, search the screen number from the hit area address table.

That is, n = 1 is set in step 64, then the coordinates of the starting and ending points are read in step 66, a hit area frame display request is issued in step 67, and the above operation is repeated until all n are completed.

Note that step 61 is the hit area display request receiving means 9, and steps 62 to 68 are the hit area display requesting means 10.
