Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device in which a coordinate input means such as a transparent digitizer is combined with a display means such as a CRT.

[Prior Art] In the field of graphic data input that combines computer data processing and image processing technology, machines and humans can interact conversationally ('I4 There is a growing need for a man/machine interface that can advance the process.

This type of man/machine interface includes a combination of a display device such as a liquid crystal display under a transparent digitizer or tablet, a combination of a CRT and a light pen, or a transparent touch panel in front of a display device such as a CRT. An arithmetic method has been devised that overlaps the . In other words, it can be called a coordinate input/display device in which a coordinate input device and a display device are integrated. In such a device, when each item of the menu list is divided into several areas on the screen and the item in the area that includes the position pressed with the pen tip or fingertip is selected, the corresponding area is sufficiently wide, no major problem will occur even if the input coordinate values of the pen tip or fingertip deviate somewhat from the intended position.

However, for example, CAD (CONPU), which has been attracting attention recently,
There are various problems in fields such as TERAIDED DESIGN that require precision in graphic creation. FIG. 2 is an example of a CRT display when designing printed wiring using CAD. As shown in the figure, densely packed printed wiring lines run horizontally on the CRT screen. Now, let's assume that the cursor is now at point A at the top left of the screen.

There are two methods for moving the cursor from point A to point B in the wiring dense area. The first method is to reach point B by moving the cursor through the printed wiring as shown in trajectory C. This can be easily understood by assuming that a new printed wiring is drawn on the trajectory C. The second method is a method of reaching Katsumi in substantially the shortest distance, just like on a trajectory.

[Problem to be solved by the invention] If the above two methods are analyzed and considered, the coordinate input/
It can be seen that the display device requires the following viewpoints. In other words, ■: The configuration is such that the direction in which the cursor should be moved and the distance to which the cursor should be moved are known; ■; From the perspective of coordinate input, the problem is to quickly and accurately indicate the target position. It is. This requires the ability to quickly move the cursor from the current cursor position to the target position, and to accurately indicate the position when the cursor is near the target position. In other words, you can indicate the target point more accurately,
To this end, the configuration must be such that the operator of the device can easily visually recognize the position of the target point. It is also important not to lose sight of the direction and distance to the target. However, with respect to this point of view, when the conventional coordinate input indicating device is a stylus pen or a fingertip, the figure displayed at the tip is hidden, making it difficult to accurately indicate the desired position. In particular, when the resolution of a coordinate input device such as a touch panel is small compared to the resolution of a display means such as a CRT, any minute section displayed on the CRT etc., for example 1
It is not possible to accurately indicate the dot. Also, when trying to point to a dot displayed between a certain grid point and the grid point next to it on a touch panel, etc., in some cases, the point displayed directly below the wrong grid point may be indicated. I end up giving instructions.

■20 was a problem with the conventional technology from the perspective of how to reach a certain target point. However, as can be seen from the example of trajectory C in FIG. 2, the problem of reaching a certain target point is at the same time the route to reach that target point. That is, in the example of the trajectory C, what should be done to reach the target point B while avoiding the printed wiring that is already displayed? In other words, the problem of keeping the cursor position at a predetermined distance from the existing image is to one-dimensionally display the point indicated by the operator as a locus. In this respect as well, the conventional technology is insufficient because only the points immediately below the coordinate grid points that can be input using a touch panel or the like can be accurately indicated, that is, displayed.

■Secondly, in order to reach the target point more accurately, or to reach the target point while drawing the desired trajectory, the input instruction speed of the operator and the moving speed of the cursor (or the display drawing speed at which the trajectory is drawn) are required. However, for example, when the target point is far away, it is desirable to be able to draw the trajectory faster than the input instruction speed, while when the target point is near, the former speed can be made slower than the latter speed.

■: Not just a display device or coordinate input device,
A man-machine interface that takes the above points into account is desired.

The present invention has been made in view of the problems of the prior art described above, and its purpose is to propose a display device that can accurately move a moving figure to a desired target point at a desired moving speed. .

[Means for Solving the Problems] As a means for achieving the above-mentioned problems, for example, the display device of the embodiment shown in FIG. The tablet 1 is placed so that it overlaps with the tablet 1, and the display coordinates and input coordinates of both have a predetermined correspondence relationship. When the figure to be moved is a figure 700, the figure 700 is specified, for example, by moving the cursor 400 eight times within the figure 700. The display device is provided with a figure movement instruction area 500 in which an instruction to move the figure 700 can be entered so that the display surface of the CRT display 2 and the touch panel 1 overlap each other. Further, the display device further includes a coordinate displacement detection means 40 for detecting the direction, distance, and speed of coordinate displacement of input coordinates input with a finger or the like into the figure movement instruction area 500.
1 is connected to a figure moving means 403 for moving the figure 700 to a desired position.

[Function] In the above configuration, the coordinate displacement detecting means 401 detects the movement of the finger when an input is made to a predetermined area on the touch panel 1, that is, the figure movement instruction area 500, as the direction, distance, and speed of the coordinate displacement. The figure 700 is moved according to the detected speed, for example, when the displacement speed is higher than a predetermined speed, the distance is one or more times the distance traveled by the finger, and when the displacement speed is lower than the predetermined speed, the distance moved by the finger is moved. For example, the target figure 700 is moved by a distance less than one time. In this way, the movement of the figure 700 can be controlled by the operator's input to the movement instruction area 500, for example, with a finger, and the movement speed of the figure 700 can be controlled depending on when the figure 700 is far from and near the target point to which it should be moved. Since it can be made variable, it has good operability and can move quickly and accurately to a desired target. Furthermore, if the movement instruction area SOO is also moved parallel to the movement of the graphic 700, the operability will be further improved. .

(The following is a blank space) [Examples] Examples according to the present invention will be described in further detail below with reference to the accompanying drawings.

<Block Configuration of Embodiment> FIG. 3(a) is a block configuration diagram of a coordinate input device with a display function according to an embodiment. 1 is a touch panel that is attached to the screen of a CRT display 2 so as to cover the screen. C
The RT controller 3 retrieves the image data created by executing the program of the CPU 4 from the image memory 5.
Display on RT display 2. The program and data of CPtJ4 are stored in memory 6. Further, a position touched by a finger or the like on the surface of the touch panel 1 is detected by the touch panel control circuit 7. This is CPtJ4
is read out as coordinate values. CPU 4 accesses these data via bus 8. The keyboard 9 is used to input operations necessary for image display and coordinate input.

For example, they are the "mode" key ao, the "r input" key 81, etc. How to use these keys will be described later.

FIG. 3(b) shows an example of a CRT screen. The number of pixels on this screen is, for example, 640 dots horizontally and 400 dots vertically. Then, the coordinates of the upper left pixel are (OlO), and the upper right corner is (0,
633), the lower left edge is (399, O), the lower right edge is (399, O)
, 633).

Generally, when data corresponding to pixels coordinated in this way is stored in the image memory 5, eight pixels in the horizontal direction correspond to one unit of memory location, that is, one byte, and are stored sequentially in the horizontal direction. Generally, one dot line after one dot line is stored sequentially, and data for one screen is stored as a rask image. In this way, the CPU 4 can handle the contents of the image memory 5 in the same way as the normal memory 6. Under the above environment, points are formed at arbitrary positions on the screen of the CRT display 2. Draw a line from any position to any position. In addition to drawing programs such as drawing a circle centered on an arbitrary position, bit-bang data of an arbitrary rectangular area on the screen can be transferred to the memory 6 in a specific format, and vice versa, the data in the memory 6 can be transferred to the screen. There is a drawing program that outputs the output to an arbitrary position. This is realized by the CPU 4 rewriting the contents of the image memory 5 and transferring data to and from the memory 6. When rewriting the contents of the image memory 5, in units of bits corresponding to each pixel data, when the source data for rewriting is S and the pixel data of the image memory is D, a logical operation α such that D=α・S Another method is to use the results of the process as new data in the image memory. For example, if the screen is reversed, α is the exclusive OR and S is “
This can be achieved by setting the value to 1”.

The above is an example in which graphic processing is performed as a program of the CPU 4, but some CRT controllers 3 have these functions, and in this case, the CPU 4 transfers drawing commands to the CRT controller 3.
Just send it to controller 3.

On the other hand, if you press any point on the screen with your finger, the touch panel 1 is installed on the screen, and the coordinate position is displayed on the CP.
U4 can be read from the touch panel control circuit 7.6). The touch panel control circuit 7 may pass the coordinates in the X direction and the coordinates in the Y direction of the pressed position to the CPU 4 as a numerical code or as a binary value.

In any case, touch panel! Since the coordinates of , the coordinates on the CRT display 2, and the coordinates in the image memory 5 uniquely correspond to each other, input the coordinate value on the touch panel 1 when you press the top of the pixel while looking at the CR7 screen.
It is sufficient if the coordinates (x, y) of the image memory 5 can be calculated from the values.

<Graphic Cursor> Now, FIG. 4 shows an example of the basic configuration of the graphic cursor used in the embodiment. The display surface of the CRT display 2 is provided with three display areas: a cursor 10 consisting of four L-shaped figures, a cursor movement instruction display area 11, and a coordinate input instruction display area 12. Further, the cursor movement instruction display area 11 is provided on the coordinate input surface of the touch panel 1.
a cursor movement instruction input area 14 corresponding to the coordinate input instruction display area 12; and a coordinate input instruction input area 13 corresponding to the coordinate input instruction display area 12.
Two areas are provided. Operator is cursor 10
In order to move the center P to the desired display position, input the movement direction and distance in the cursor movement instruction input area 14 while visually checking the cursor movement instruction display area 11 using, for example, a finger or a stylus pen. . Also, while visually checking the display of the coordinate input instruction display area 12, the coordinate input instruction input area 1
By pressing 3, the user instructs that the pixel indicated by the center P of the cursor 10 should be input as a new image (dot).

A cursor configured in this manner will be referred to as a "graphic cursor" in this embodiment. As shown in FIG. 4, various operations can be performed by appropriately combining the graphic cursor consisting of five components. For example, the cursor 10, the cursor movement instruction display area 11, and the cursor movement instruction input area 14 are set in areas close enough to each other that they will not be hidden even if the power tool 10 presses the cursor movement instruction input area 14 with a finger. Make it. cursor f
Move your finger on the Hjl instruction display area 11 to move the cursor 1
When 0 is moved, the cursor movement instruction display area 11 and the cursor movement instruction input area 14 are also moved together with the cursor 10. In this operation, the cursor 10 moves while keeping a short distance from the finger as the finger moves, and since the cursor 10 is separated from the finger, it is not hidden by the finger, so it is extremely easy to operate. It is highly valuable as a display device because it can reach the target point accurately and efficiently.

In addition to the configuration of (2); (2), a coordinate input instruction display area 12 and a coordinate input instruction input area 13 are also set close to the cursor 10, and when the cursor 10 moves, these areas also move. In addition to the features described in (2), this method provides extremely good operability in terms of coordinate input (an example of this is shown in FIG. 5(a)).

(b)).

(2): In the above two configurations, the cursor movement instruction display area 11 and the coordinate input instruction display area 12 are graphically displayed. For example, the coordinate input instruction display area 12 and the coordinate input instruction input area 13 are connected to the keyboard 9.
For example, the above-mentioned "input" key 81 may be used instead. Also, the cursor movement instruction display area 11 and the cursor movement instruction input area 14 may not be moved together with the cursor 10, but may be set as fixed areas as shown in FIG. 6(C).

■: Also, instead of the cursor, general figures can be used as the 8th shift object.

(Specific examples of graphic cursors) Two examples of the configuration of graphic cursors are shown in Figure 5 (a).
, shown in (b).

In the graphic cursor 100 of FIG. 5(a), the cursor 10 and the coordinate input instruction display area 12° and the coordinate input instruction input area 13 are aligned and overlapped (this overlapping area is called the coordinate input instruction area 3°). ), a movement instruction area 4°, in which the cursor movement instruction display area 11 and the cursor movement instruction input area 14 are overlapped, is set near the coordinate input instruction area 300. The entire graphic cursor 100 in FIG. 5(a) is formed in a rectangular area with a horizontal length of LIX and a vertical length of Lly. L-shaped areas 20a, 20b, 20
20c and 20d constitute the cursor 10, and the reason for having such a structure is to make the central part P of the cursor 10 easy to identify. In order to highlight the difference between the conventional graphic cursor and the graphic cursor of this embodiment,
In this implementation, the center of the character shape is hereinafter referred to as the "substitute position", and the cursor 10 and the movement instruction area 40 are separated, and the coordinates of the center P of the cursor become the "input coordinates" for input by a finger or the like. This is because of the characteristics of the example.

Set the reference coordinate position of the graphic cursor 100 to the upper left corner (
Xb, y b), the relative lengths of the alternative position P are horizontal distance ΔXI% and vertical distance ΔY1. That is, the alternative position P is (Δ
Xl+ΔY1). The movement instruction area 40 is represented by a rectangle, and the horizontal length of the area is Q2.
The X% vertical length is Q2y, and the upper left corner position which is the reference point of the area is (Xb%yb+23).

Further, the reference position of the coordinate input instruction area 30 is (xb,
yb), its horizontal length is 0 and its vertical length is 11y. In this way, by providing the reference coordinates of each figure and the distance therefrom, it is easy to draw a desired graphic cursor figure. That is, if the reference position is moved, the graphic cursor 100 will continue to move.

Figure 5(b) shows the graphic cursor 1 in Figure 5(a).
This is an example of a graphic cursor 200 that has a slightly different function from 00. This graphic cursor 200
is formed in a rectangular area with a horizontal length of L231% and a vertical length of L2y. The offset of the alternative position Q is ΔX2 horizontally and ΔY2 vertically. What is particularly different from the graphic cursor 100 is that the movement instruction area 60 is different from the graphic cursor 2.
00, and therefore the coordinate input instruction area 50 (this area is also the movement instruction area at the same time)
is the remaining area of the graphic cursor 200, excluding the rectangle 70 representing the area where only movement is instructed from the movement instruction area 60. The horizontal length of this coordinate input instruction area 50 is x, the horizontal length is 14y, and the offset from the reference position is 0'' both horizontally and vertically. , so that it is possible to input coordinates continuously, if the coordinate input instruction area 50 is moved while being pressed so that the alternative position Q is not hidden, the movement instruction and the coordinate input instruction can be performed at the same time. .

Graphic cursor operation> Figure 6 (a) shows the graphic cursor 100 (Figure 5 (
An example of the operating method of a)) is shown below. CRT display 2
At the above cursor starting position, move your finger while pressing the movement instruction area 40 without releasing your finger. Along with this movement, the entire graphic cursor 100 or 200 moves.

This movement is performed by changing the value of the reference coordinates (Xb + Vb). As can be seen from the figure, it should be noted that the alternative position P is not hidden by the finger during movement. When the alternative position P reaches the target position, by pressing the coordinate input instruction area 30 with a finger, the coordinates of the target position are input.

FIG. 6(b) shows the state in which the apparatus is used in continuous input mode (control procedure shown in FIG. 11) by operating the "mode" key 80. In this continuous input mode, when you move your finger while placing your finger on the movement instruction area 40 of the graphic cursor 100, the graphic cursor 100 will of course move as your finger moves, but at the same time the coordinates of the alternative position P will be input continuously. Coordinate input (if displayed as is, it will become a trajectory) can be obtained.

The example shown in FIG. 6(c) has a configuration in which each of the components shown in FIG. ．． Coordinate input instruction display area 12. The coordinate input instruction input area 138 and the coordinate input instruction input area 14 do not move and remain at the fixed position shown in the figure.

In the example shown in FIG. 6(d), the coordinate input instruction is performed using the coordinate input key 81 on the keyboard 9.

Examples of other graphic cursors> Figure 5 (c),
(d) shows examples of other graphic cursors 300, 600. As shown in FIG. 5(C), an outer frame 301 and an inner frame 302
The area between is designated as a movement only instruction area, the inside of the inner frame 302 is an input instruction area 304, and the inside of the outer frame 301 is a movement instruction area 303. Note that the alternative coordinates R are expressed by the centers of the four L shapes as described above. In this way, by setting the area around the alternative coordinates as the input instruction area and the surrounding area as the g-motion instruction area, the alternative coordinates R can be placed at any arbitrary position on the top, bottom, left, and right edges of the screen. As shown in FIG. 5(d), the input instruction area 6 is placed in a place other than around the alternative coordinates S.
01 may be defined. This is particularly effective when the size of the graphic cursor is limited and when the trajectory can be input even at a location far from the alternative coordinates S. Of course, the area 602 may be used only for movement, and the area 601 and the vicinity of the L-shape may be used as input instruction areas.

<Drawing program and coordinate input program> = Figure 7 (c)
represents an example of drawing a circuit diagram on the CRT display 2. A straight line (printed wiring) is drawn from point E to input bin F of gate 101. Point F is gate 1
As mentioned above, it is difficult to distinguish between point F and point G and move the cursor six times with a conventional graphic cursor because the input pin 02 is close to the point F and point G. An example of this drawing program is shown in FIG.

Now, input coordinates and the like are required for a drawing program to draw, and a coordinate input program provides such information. The coordinate input program has the role of moving the cursor and providing input coordinates to the drawing program.

Examples of coordinate input programs are shown in Figures 10, 11, and 12.
Figure, Figure 13.

It is shown in FIGS. 14 and 15. The coordinate input program is CP
Timer value 105 at a predetermined time interval by U4 (Figure 8)
It is called and executed independently from the drawing program.

The arrangement of the drawing program and the coordinate input program in the memory 6 is as shown in FIG. 7(b). FIG. 7(C) is a diagram showing an interface between a drawing program and a coordinate input program. From the coordinate input program, 0NOF
F change flag, 0FFON change flag, start coordinates,
End coordinates.

ON coordinates, ON flags, etc. are passed to the drawing program.

These pieces of information are stored in the memory 6 by the coordinate input program (see FIG. 8). The drawing program and the coordinate input program are multi-processed. The drawing program reads out this information stored in the memory 6 and draws according to the control procedure of its own program.

<Control procedure of the drawing program> FIG. 9 shows the control procedure of the drawing program. Figure 7 (a
) is a simple program to draw a straight line like the one shown in . In step S2, a menu necessary for this drawing program is displayed. In step S4, the process waits for the 0FFON change flag 99 to be set. This 0FFON change flag 99 is set by the coordinate input program, and when this flag is "1", it indicates that the cursor movement instruction input area 14 is pressed for the first time with a finger or the like. At this time,
Start coordinates 102 are stored in the memory 6 by a coordinate input program to be described later. 0N in step S6
Wait until the OFF change flag 101 is set. This 0
The NOFF change flag 101 is a flag indicating that the finger has been removed from the cursor 6 shift instruction input area 14. When this flag is 1", the end coordinate 103 is stored in the memory 6. In step S8, the start coordinate 102 is stored in the memory 6.
The address in the image memory 5 corresponding to the end coordinate 103 is calculated, and all pixels between them are set to "1". In this way, points E and F shown in FIG. 7(a) are easily connected by a straight line.

Coordinate Input Program> Next, an example of the coordinate input program most characteristic of this embodiment will be described below. As described above, this coordinate input program is periodically called and executed at predetermined time intervals (timer value 105).

<Control Procedure of Graphic Cursor 100> FIG. 10 shows a control procedure accompanying the operation of the graphic cursor 100 shown in FIG. 5(a). In step S60, it is determined whether any part of the touch panel 1 has been pressed. If it is determined in step S60 that there is no input, step S9
Proceed to step 4. Since the finger is not touching, the moving flag 91 is set to "O" in step S94. Flag 91 during this 8th shift
indicates that the cursor control instruction input area 14 has been pressed once. In step 396, the ON flag 94 is checked. This ON flag 94 indicates that the finger pressed any point on the touch panel 1 last time. When the ON flag 94 is "0", the coordinate input program is ended, and when it is "1", in step 398, the 0NOFF change flag 101 is set to "1". In step 5100, the ON coordinate 104 is registered as the end coordinate 103, that is, the previous input coordinate value, the coordinate value immediately before the finger is released. Then, in step 5102, the ON flag 94 is set to "0" and the coordinate input program is ended. After a predetermined period of time has elapsed, this coordinate input program is executed again.

If any point on the touch panel 1 is pressed in step S60, it is determined that there is an input, and the process proceeds to step S62, where the touch coordinates 106 (X') are pressed.

y'). At this time, depending on the control method of the touch panel 1, coordinate values (X', y') may be input first, and presence or absence of input may be determined by checking the range of these values. In step S64, the touch panel 1 and the image memory 5
A coordinate transformation is performed according to the correspondence with the coordinates on the screen, and the coordinates are converted to on-screen coordinates and registered as temporary coordinates 90. In step S66, a moving flag 91 indicating whether a finger touched the movement instruction area at the time of the previous sampling is checked, and if this flag is "0", that is, cursor movement has not been instructed at the time of the previous sampling. Then step S72
Proceed to. In step S72, the temporary coordinates 90 (this is (X,
y)) and (x.

y) is within the movement instruction area 40.

This judgment is made as follows, assuming that the reference position is (xb, yb),
In this case, it is determined that the movement instruction area 40 is inside.

If it is outside this area, the process proceeds to step S76, where the moving flag 91 is set to "0", and in step S80, it is determined whether the temporary coordinates 90 are within the coordinate input instruction area 30. This check determines that it is within the coordinate input instruction area 30 when (夛：辷は连：：：＝). If it is within the coordinate input instruction area 30, the ON coordinate is 10 in step S84.
4 at the alternative coordinates 95, that is, the coordinates of the point P within the cursor. The ON coordinate 104, which is the information to be passed to the drawing program, is (X''.

X''), it will be expressed as (夛：二夛：：衾口：. In step S80, the temporary coordinates 9
0 (the touched point) is outside the coordinate input instruction area 30, the ON coordinate 104 is registered as the value of the temporary coordinate 90 in step S82. This is because it is assumed that the operator touched the touch panel 1 for a purpose other than using the cursor.

Then, the process advances to step S86. Here, ON flag 94
Check. The ON flag 94 is a flag indicating that the coordinates were input in the previous sampling, and this is “
If it is 1'', the program is terminated, and if it is "0", it means that it was off at the previous sampling time and on this time, so the process goes to step S88 to process the change.Here, it is determined that the change to the ON state has occurred. Indicating 0FFON change flag 9
9 is set to "1" and the start coordinates 102 are set in step S90.
is registered as the value of the ON coordinate 104, and in step S92
The N flag 94 is set to "1" and the program ends.

If it is determined in step S72 that the area is within the movement instruction area 40, the moving flag 91 is set to 1" in step S74, and the process proceeds to step 398. Here, the value of the temporary coordinates 90 is set to the old coordinate 9
Register as 3. This is to store the original position of the finger in order to move the graphic cursor 100 by moving the finger while touching the movement instruction area 40 in a step to be described later.

When the moving flag 91 is "1" in step S66, it means that the user touched the movement instruction area 40 last time and is currently touching the screen. Therefore, step 368. S70
, and move the graphic cursor 100 according to the movement of the finger. That is, in step S68, new values of the reference coordinates of the graphic cursor 100 are calculated. This represents the displacement of the finger in the X and X coordinates, δX and δy, respectively.
Then, δX ← (X coordinate value of temporary coordinates 90) - (X coordinate value of old coordinates 93) δy - (X coordinate value of temporary coordinates 90) - (X coordinate value of old coordinates 93) Therefore, the graphic The new reference coordinates (Xb, yb) of the cursor 100 are updated as follows. Then, in step S70, the graphic cursor 100 is moved. That is, the display mechanism (graphic cursor display circuit, not shown) of the graphic cursor 100 may be updated with new reference coordinates. Next, in step S98, the values of the temporary coordinates 90 are transferred to the old coordinates 93 in preparation for the next reference position movement.

With the above configuration, the coordinates of an arbitrary position can be determined by touching the movement instruction area 40 and moving the finger, setting the center of the four L-shaped areas, that is, the alternative position P, at the desired position, and then instructing the coordinate input. This is possible by touching the area 30 with your finger.

<Control procedure for graphic cursor 200> With the configuration of the graphic cursor 100 described above, it is difficult to input an accurate trajectory.

To cope with this, the entire graphic cursor 200 is regarded as a movement instruction area, as shown in FIG. 5(b), and part of it is set as a confirmation instruction area 50. A control procedure for operating the graphic cursor 200 as described above is shown in FIG.

In step 5110, it is determined whether touch panel 1 has been pressed. The control procedure when the button is not pressed is substantially the same as steps S94 to 5102 in FIG. 10, so a description thereof will be omitted.

If it is determined that the touch panel 1 is being pressed, it is determined that there is an input and the process proceeds to step 5112, where the touch coordinates 106 are
Input (X', y'). In step 5114, the touch coordinates 106 (X').

y') is subjected to the same coordinate transformation as performed in step S64 of the previous embodiment, converted to coordinates on the screen, and registered as temporary coordinates 90. In step 5116, a moving area flag 96 is set to indicate whether or not a finger was touched somewhere within the graphic cursor 200 during the previous sampling.
Check.

When the internal area flag 96 is "1", that is, when the graphic cursor 200 was not pointed at last time, the process advances to step 5122. In step 5122, it is determined whether the temporary coordinates 90 (x, y) are coordinates within the graphic cursor 200. This determination can be made by referring to FIG. 5(b) and determining that the position is within the graphic cursor 200 when the value is 1.

If the temporary coordinates 90 are not within the graphic cursor 200, the process advances to step 5130, and the in-movement area flag 96
is set to "0", and in step 5132, the coordinate input flag 107 is set to °°0°°. Since the coordinate input flag 107 indicates that the coordinate input instruction area 50 of the graphic cursor 200 has been touched by a finger, it is cleared to "0" since the graphic cursor 200 has not been touched. Therefore, since the finger is currently touching a place other than the graphic cursor 200, in order to use this position as the input coordinate value, in step 5146, the ON coordinate 104 is touched.
The value of is registered as the value of temporary coordinate 90. and step 51
At step 54, the ON flag 94 is checked. ON flag 9
If 4 is "1", the program is terminated, and if it is 0, it means that it was off at the previous sampling time and on this time, so proceed to step 5156.Here, it is confirmed that the change to the ON state of touch panel 1 has occurred. Set the 0FFON change flag 99 to "1", register the start coordinate 102 with the value of the ON coordinate 104 in step 5158, and register the start coordinate 102 with the value of the ON coordinate 104 in step 316.
0, the ON flag 94 is set to '1' and the program ends.

When it is determined in step 5122 that the finger is pointing inside the graphic cursor 200, the process proceeds to step 5124 and first sets the moving area flag 96 to 1''.Furthermore, in step 5126, the temporary coordinates 90 are set to the coordinate input instruction area 5.
It is checked whether it is within 0, and only when it is within the coordinate input instruction area 50, the coordinate input flag 107 is set to 1° in step 5128. If not, this 1
Since 07 has been cleared in steps 5132 and 5136, it remains at "0".The check to see if it is within the coordinate input instruction area 50 in step 5126 is based on the formula (夛：""：：Hi：UNI) You can judge accordingly.

The process then proceeds to step 3148, where the value of temporary coordinates 90 is registered as old coordinates 93. The meaning of this step 3148 is the same as step S78 described above. Step 5
At step 150, it is checked whether the coordinate input flag 107 is "1". When this flag is "0", that is, when the coordinate input instruction area 50 is not touched, this program is terminated, and when it is touched, the coordinate value of the alternative position of the graphic cursor 200 is turned ON in step 5152. coordinate 1
Register as a value of 04. The coordinates (x
', y') can be calculated as follows.

(夛UNI 蕃++ 会辷・ This allows the coordinates of the point Q indicated by the graphic cursor 200 to be set to the ON position [104
It becomes possible to use it as

If step 8154 and subsequent steps are executed as described above, the change to the ON state can be detected in the same way.
A change to the OFF state when the finger is released can also be input in the same way.

When the moving area flag 96 is 1" in step 5116, the graphic cursor 200 was touched last time,
You are still touching the screen. Therefore step 5
11B and 5120, the graphic cursor 200 is moved to fHj according to the finger movement. In step 5118, new values for the reference coordinates of the graphic cursor are calculated. This is the displacement of the finger in the X coordinate and δ in the X coordinate, respectively.
Assuming X and δy, δX = (X coordinate value of temporary coordinates 90) - (X coordinate value of old coordinates 93) δy = (X coordinate value of temporary coordinates 90) - (X coordinate value of old coordinates 93) , the reference coordinates of the graphic cursor 200 (
Xb+yb) may be set to (夛:二夛::g夛). Then, in step 5120, the graphic cursor 200 is moved.

Then, by executing step 5148 and subsequent steps as described above, the coordinates of the coordinate specified position of the point Q within the graphic cursor 200 can be continuously input by moving the finger while touching the coordinate coordinate input specifying area 5o. is also possible. That is, as a drawing program (different from Fig. 9),
If the ON coordinates 104 obtained from the coordinate input program are arranged to be continuously expanded into the image memory 5, the coordinate input can be obtained as a locus. The coordinate input program (Figure 10) that executes the above-mentioned Figure 7(a) is particularly effective when viewed as a display device, but the coordinate input program in Figure 11 has no significance as a program for a coordinate input device. be.

Continuous coordinate input> Figure 12 shows the graphic cursor 100 in Figure 5(a).
This is a modification example in which coordinates are input continuously using . To do this, operate the "mode" key 80 on the keyboard 9 to switch to the continuous input mode (that is, the continuous mode flag 98 becomes 1").The only difference from the flowchart in FIG. 10 is step S79. In step S79, the continuous mode flag 98 is checked, and if this flag is 1, the process proceeds to step S84, but if it is 0, the program is terminated.

Furthermore, instead of the "mode" key 80, an area for mode switching instructions can be set on the screen. In that case,
For example, a mode switching instruction area is set in a part of the movement instruction area 40.60, and a step of checking 0FF-〇N change to this area is inserted between steps S66 and 372, and 0FF in that area is checked. -ON or ON-〇 The continuous mode flag 98 is inverted every time the FF changes.

On the other hand, when setting the mode switching instruction area outside the movement instruction area 40.60, the step of checking 0FF-ON or ON→OFF change is performed in step S80 and step S8.
Put it between 2. However, in this case, if there is a mode switching instruction, the program may be terminated without proceeding to step S82.

In this way, it is possible to input coordinates by using alternative position coordinates while appropriately changing the coordinate input method to either single shot or continuous input, thereby greatly improving operability.

<Coordinate Input Instructions from the Keyboard> In the embodiments described above, coordinate input instructions are performed by inputting them onto a display figure (that is, by inputting them to the touch panel 1). The embodiment shown in FIG. 13 partially corresponds to the embodiment shown in FIG. 6(d), and coordinate input instructions are performed from the keyboard 9. This instruction is made using the "input" key 81 as shown in FIG. 6(d). The flowchart shown in FIG. 13 is basically the same as the flowchart in FIG.
．． In place of S84, the "input" key 81 is pressed in step S95.
This is to confirm the presence or absence of a coordinate input instruction from.

<Variable Cursor Movement Speed> In the embodiments described above, when an input is made to the movement instruction area 40 or 60, the movement speed of the graphic cursor is, in principle, the same as the movement speed of the finger. In the embodiment described next, the moving speed of this cursor is made variable.

When moving the cursor 8 times, when the target is far away, the cursor is moved 8 times at high speed, and when the target point is near, the cursor is moved at a slower speed than the finger movement speed to improve accuracy.

For this purpose, step S68 in FIGS. 10, 12, and 13 and step 3118 in FIG. 11 are changed as shown in FIG. 14. That is, step S of the flowchart
68 or step 8128, the process jumps to step 5tool in FIG. 14 and executes it. First, let the displacement of the finger be δX and δy in the X coordinate and the X coordinate value of coordinate 90) - (X coordinate value of old coordinate 93) is calculated. Then, in step 51002, γ-J (δx)2 + (δy)2 is calculated, with the amount of movement of the graphic cursor being γ(107), and the constant distance threshold R stored in the memory 6 is calculated.
Compare with (111). The amount of movement γ(107) is R(1'
ll), execute step 5IO03; otherwise, skip step 51003 and execute step 51
Proceed to 004.

In step 31003, the results of multiplying the movement amounts δX and δy by the constant α (108) are again set as the respective movement amounts. Here, by setting the constant α (108) to be less than 1, the 8-force amount is changed to be smaller than the actual finger movement. Conversely, if the amount is 1 or more, the speed can be increased. In step 51004, the reference coordinates (xb, 3/b) of the graphic cursor are set to (夛：二夛す、+5夛).

With the above configuration, an accurate position instruction can be made by touching the movement instruction area, moving the finger as it is, quickly moving the center of the four L-shaped areas, that is, the alternative position, to the vicinity of the target position, and then accurately specifying the position. When performing alignment, by moving the fingers slowly, it is possible to move to any desired position even if the resolution of the coordinate input device is small. Generally, when specifying an accurate position, the user first performs general alignment quickly and then slowly when specifying the final position, so there is no sense of discomfort since this is consistent with human behavior.

Now, the program shown in FIG. 14 is called periodically. Therefore, although the movement amount calculated by the above-mentioned formula is in dots, it has a meaning as a speed because of the regularity of the program call. Here, let us derive the constant threshold value R(111).

If the cursor movement speed is less than 30 mm per second as fine adjustment mode, and if it is coarse adjustment mode that gives the operator an appropriate feeling of operation, then within this 30 mm, the dot density of the screen should be When 4 dots/mm, 4
x30 dots are included.

That is, if the moving speed of the cursor is v, then ■.

=120 dots/second. Therefore, if the coordinate input program is called every t9 seconds, then R=t, -V,
=t, For example, if the coordinate input program is 100. , then R(111
)=12 [dots]. The movement of the finger at this time is γ
, a dot, the finger movement speed ■1 is V, = γ, /1. [dots/second]. Here, the unit of γ is [(actual distance of the screen)/(
The length between the coordinates of that length)].

(Variation example of variable time) Now, change the coordinate input program to 100. As mentioned above, if the coordinate input program is called every time, the threshold value R is 12.
When the amount of finger movement is less than 12, the speed is 30 mm/
It can be determined that it is less than 1. Therefore, what to do when the resolution of coordinate input is low will be described below. Even in such a case, the alternative position of the cursor must not be able to accurately indicate a specific point for each dot. Therefore, even in the case of a touch panel 1 that can only input coordinates every n dots (n is a natural number) (for example, when the minimum width is 1 mm, coordinates can be input every 4 dots), the above constant α (108) can be set to r 1 /
If set to nJ, when the input displacement is γ, the displacement of the alternative position coordinates when moving slowly will be γ/n, and if the minimum displacement is n dots, the displacement of the alternative position coordinates will be 1 dot. , it becomes possible to specify an arbitrary position on the one-dot vehicle position.

However, in the above example, an example of sampling 10 times per second (Looms sampling rate) is shown, but if you want to perform smoother movement or input a trajectory even faster, you need to increase the sampling rate. There is. In such a case, the displacement for each sampling becomes small, and the above method cannot distinguish between high and low displacement speeds. For example, if sampling is done every 10 m, R = 1.2, which means that the minimum
In the case of coordinate input for each dot, γ≧4 should be satisfied, but
The condition γ<R(111) only holds true when γ=0, and the above effect is lost. In such a case, one method is to calculate and store the average value of displacement in past samplings as γ',
The condition γ'<R may be used in step 51002.

Next, as one mode of operating the graphic cursor, there are cases in which the finger moves suddenly and greatly. To deal with this, the control shown in the flowchart in FIG. 15 may be used instead of the flowchart in FIG. 14. That is, after step 5tool, in step 5IOIO, the movement amount γ is calculated as γ-J(δx)2+(δy)2, and in step 5IOII, it is checked whether γ is "0", and if it is other than "0゛°, In step 51012, the average displacement γ' is calculated as γ'←γ/β.The initial value of this parameter β (109) is set to "1".When γ=0, step 5101
4, the average displacement γ' is also set to o", and in step 51015, the value of β (109) is incremented by 1. By doing this, even if γ (107) suddenly increases from O", Since β (109) is an amount commensurate with the time when γ (107) is 0'', step 5101
By setting γ(107)/β(109) in 2, sudden movement can be alleviated. Also, step 51013
By resetting β(109) to “1”, γ(
107) is a continuous large value, the relaxation of the displacement is only at the beginning, so that a displacement γ' commensurate with that displacement can be obtained from the next time. The concept of the above method is shown in FIG.

By doing this, it becomes possible to deal with cases where the resolution of coordinate input is low and the displacement "O" continues and the displacement suddenly increases at a certain boundary.

Furthermore, in the above embodiment, the displacement γ is equal to the threshold value R(111)
When smaller, the horizontal displacement δX and vertical displacement δy have a coefficient α
(108), the coefficient α(108) is defined as the integral number f(γ) of the displacement γ, and step 51002
(S1002') may be omitted and instead of step 51003, (g夛二gゆめ手() may be used. This open number f(γ) is expressed as f(γ) = (1/.: γ≧ 8 If the program is called every 100m as γkuR, then R
-12. Therefore, a plurality of α1°α2. ...α
The selected α
may be multiplied by r. Note that if α is not only less than 1 but also greater than 1, it becomes possible to rapidly move the finger and flick the graphic cursor.

Application to General Figures By the way, the various embodiments described above are all examples of cursors or graphic cursors. However, the present invention is not limited to application to cursors or graphic cursors. That is, it is naturally possible to use a general figure as the moving target. In this case, the cursor or graphic cursor of the above embodiment is used to specify the figure to be moved, and the specified figure is simply moved by a method similar to the movement of the cursor described above, that is, by parallel movement.
