Description

The present invention relates to an operation status display method for displaying the operation status of a device on a display screen.

[Prior Art] In a conventional tablet-type figure input touch panel,
To decide where to start drawing on the CRT screen, trace the touch panel with a brush while pressing an appropriate key on the computer, such as the shift switch, and the cursor appears on the screen. After I took it to the desired place, I was able to draw on the CRT by releasing the key.

[Problems to be Solved by the Invention] In such a conventional touch panel, in order to fix the drawing start point, in addition to tracing a brush on the panel, a predetermined key on the computer side must be simultaneously operated. There wasn't. Therefore, if the timing of releasing the key is incorrect, the drawing start point may deviate from the intended position, which makes drawing start very troublesome. Therefore, the input work efficiency was poor.

That is, it is necessary to elapse a predetermined time in order to fix the drawing start point as described above, but in the past, the operator could not know the elapsed time.

An object of the present invention is to make it possible to immediately check how much time has elapsed from the predetermined operation when performing a predetermined operation on a device and then performing a new operation. Is.

[Means and Actions for Solving the Problems] Means and actions of the present invention are as follows.

A method of displaying an operation state of a device on a display screen, which displays a graphic scale showing the maximum remaining time when a predetermined operation is performed, and then displays the next operation after the predetermined operation is performed. The time until a change is made by a new operation is measured, and the graphic scale figure is sequentially changed and displayed according to the change in the measurement time, and when the measurement time matches the maximum remaining time,
The above-mentioned graphic scale figure is deleted.

Therefore, when a predetermined operation is performed on the device and a new operation is performed thereafter, it is immediately known how much time has elapsed from the predetermined operation by the display form of the graphic scale. Further, when the next new operation is detected before the elapsed time matches the maximum remaining time, the initial graphic graphic is automatically displayed again instead of the change graphic. Therefore, it is possible to perform the measurement again based on the new operation.

[Structure of Embodiment] An embodiment will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a CPU (central processing unit), and the CPU 1 controls the operation of the entire system described later. A keyboard 2 for input is connected to the CPU 1, and output signals of each key of the keyboard 2 are stored in a RAM (random access memory) 3 via the CPU 1. A ROM (Read Only Memory) 4 stores a character generator and a predetermined image pattern in advance, and corresponding data is input by the keyboard 2 to the CPU 1
Called by the display control unit 5, VRAM (video RAM)
It is displayed on the screen of CRT7 via 6. A panel control unit 9 is connected to the CPU 1, and a touch panel 10 such as a tablet or a digitizer is connected to the panel control unit 9. The panel control unit 9 includes a brush or the like for designating a position on the touch panel 10. When a point on the touch panel 10 is pressed by this brush, the X and Y position data thereof is digitally detected and the X register 12, Y of the register unit 11 is detected. It is stored in the register 13, respectively.

The register unit 11 is connected to the CPU 1 by a bus line for arithmetic processing of stored data, and is externally connected to the T register 14, X1 register 15, Y1 register 16, N register 17, X2.
The register 18 and the Y2 register 19 are provided. A cursor display control unit 21 and a frame display control unit 22 are also connected to the CPU 1. The X and Y values are given to the cursor display control unit 21, and the cursor pattern retrieved from the ROM 4 is combined with the coordinate values and displayed at the X and Y positions on the CRT 7 screen. In this case, when the brush of the panel control unit 9 moves on the touch panel 10, the contents of the X register 12 and the Y register 13 also change and the CRT7
The cursor position on the top also moves according to the movement of the brush. A waiting time is designated and stored in the T register 14 in seconds from the keyboard 2 via the CPU 1. Since the CPU1 also performs the timekeeping process by the program from the ROM4, for example, the T register
If the content of 14 is T seconds, for example, every second (T-1) by CPU1,
Alternatively, a subtraction count is performed every arbitrary second, such as every 0.5 second (T-0.5). N register 17 has CP from keyboard 2
A predetermined number of dots is designated and stored via U1. This number of dots represents the number of pixels on the CRT7 screen, for example X-N
Is to display the cursor on the CRT7 screen (X value) -Nth dot. The CPU 1 subtracts a predetermined number of dots, for example 6 dots, every second or every 0.5 seconds from the value set in the N register 17. How many dots should be subtracted every few seconds from the keyboard 2 beforehand
It is input to the CPU 1 or fixedly determined by the ROM 4. Setting value of T register 14 (seconds) and N register
The set value of 17 (number of dots) and how many dots should be subtracted at every second may be entered as a program from the keyboard 2 according to the operator's proficiency, and standard values are set in advance by the ROM 4 respectively. May be. By combining these variables, the stop time of the brush is measured by a timer. In this way, the X1 register 15 has X1 = X−N which changes with time, the Y1 register 16 has Y1 = Y−N, the X2 register 18 has X2 = X + N, and the Y2 register 19 has The frame coordinates of Y2 = Y + N are stored respectively. Values of frame coordinates X1 = X-N, Y1 = Y-
N, X2 = X + N, and Y2 = Y + N are given to the frame display control unit 22, and the frame display surrounded by these straight lines is calculated and displayed on the CRT7 screen via the VRAM6. The CPU 1 sequentially stores the X and Y coordinate values recorded in the X register 12 and the Y register 13 on the memory of the VRAM 6 for a predetermined time or more, for example, 3 seconds or more. The X, Y coordinate values thus stored in the VRAM 6 are constantly displayed on the CRT 7 until the CPU 1 clears all.

Next, the operation of the above embodiment will be described with reference to the flowchart shown in FIG. 2 and FIG.

First, 3 seconds is set in the T register 14 as an average proficiency based on the experience of drawing on the touch panel 10 (step S1).
When a certain position on the touch panel 10 is pressed with the brush of the panel control unit 9, the CPU 1 reads the pressed point coordinate values X and Y,
The data is stored in the X register 12 and the Y register 13, respectively (step
S2). Next, in step S3, N = 36 (the number of dots) is set in the N register 17 in consideration of the control frame and the display frame being neither too large nor too small for the pixel width of the entire screen of the CRT 7. Then, the CPU 1 performs addition / subtraction of N = 36 with respect to the pressed point coordinates X and Y, X1 = X-N Y1 = Y-N X2 = X + N Y2 = Y + N, and the values of X1 to X2 are X1 register 15, Y1 register 16,
Store in X2 register 18 and Y2 register 19 respectively (step
S4). Based on these calculation results, the frame display control unit 22 generates the index frame W, and the index frame W and the cursor K at the center thereof are displayed on the CRT 7 via the VRAM 6 as shown in FIG. 3 (a). (Step S5). The 3 seconds of the T register 14 is also counted down every 0.5 seconds of the average speed (step S6). Next, if the cursor moves and the cursor coordinates change (step S7), the CPU 1 returns to step S1. That is, the CRT 7 will display a display frame surrounding the cursor with the new coordinates of the pressed point.
On the other hand, if the same point is pressed to stop and there is no change in the cursor coordinates, the process proceeds to step S8, and an average of 6 dots, which also affects the stop time limit, is subtracted from N (= 36). The CPU 1 checks whether or not the content of the T register 14 has become 0 (time limit of 3 seconds), and if 3 seconds have not yet elapsed, returns to step S4 and calculates new X1 to Y2. Similarly, this is to reduce the indicator frame W by 6 dots from both ends as shown in FIG. 3 (b). On the other hand, if 3 seconds have passed, step
Proceed to S10 to erase the display frame W from the screen of CRT7 (3rd
Figure (c)). The CPU 1 then VRs the cursor coordinates X, Y and a series of one-stroke X, Y coordinates drawn starting from them.
Store in AM and display as a line drawing on CRT7 (step S1
1). The CPU 1 continues to monitor whether the brush of the panel control unit 9 is separated from the plane of the touch panel 10, and the brush is touched by the touch panel 10.
Pressing upward, but while moving, returns to step S11 C
Continue to display one stroke on RT7. On the other hand, when the brush leaves the touch panel 10, the current drawing ends, and the next drawing starts from step S1 in the same manner as above.

Considering the above operation on the CRT7 screen shown in FIG. 3, it is as follows. That is, the panel control unit 9 is placed on the touch panel 10.
When pressed with a brush or the like, a cursor K and a timer display frame W are displayed on the CRT7 screen corresponding to the position as shown in FIG. 3 (a). While moving the brush on the touch panel 10 to determine the drawing opening point, the cursor K on the screen,
The index frame W also moves on the screen according to the movement. While the cursor K is moving in this way, the size of the index frame W remains at the initial size. However, if the drawing start point is determined by stopping the brush at a certain point on the touch panel 10 for a predetermined time, the index frame is displayed. W is gradually reduced (Fig. 3 (b)). In this way, the index frame W
FIG. 3 (c) after disappearing. When tracing on the touch panel 10 with a brush, an image corresponding to it is drawn on the CRT7 screen. If the brush on the touch panel 10 is moved before the marking frame W is erased, the marking frame W returns to the initial size and moves along the cursor K on the CRT7 screen according to the movement of the brush until the brush is stopped. To do.

In this way, the drawing start point can be decided only by looking at the CRT7 screen without operating the computer side including the CPU1, keyboard 2, etc., and by operating only the touch panel 10 side. Can be set accurately.

The display of the stop time of the brush is not limited to the display frame W, and a timer scale as shown in FIG. 4 may be displayed. In this case, press the brush on the touch panel,
A band-shaped timer scale 1 is displayed at the upper part of the screen (Fig. 4 (a)), and after a few seconds, the inside of the timer scale 1 is filled (Fig. 4 (b)), and after a predetermined time has elapsed, it is completely filled and drawn. Fill in the starting point ((c) in the figure). On the other hand, if the brush is moved on the touch panel before the time limit elapses, the timer scale 1 returns to its original position and the cursor K is still in the selected state, as shown in FIG. The cursor K also moves on the screen.

This may be represented by another image as long as the brush stop time is visually and intuitively displayed. Various modifications can be made by pre-setting a program for display.

[Effect of the Invention] According to the present invention, when a predetermined operation is performed on a device and a new operation is performed thereafter, how long time has elapsed from the predetermined operation is displayed in the graphic. It can be immediately known by the display form of the scale figure, and when the next new operation is detected before the elapsed time matches the maximum remaining time, the initial graphic figure is replaced with the change graphic. Is automatically displayed again, so that it is possible to perform another measurement based on the new operation.
