Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to a cursor control device, and is particularly suitable for use in moving a cursor on various display devices such as graphic displays (figure display devices) and character displays (character display devices). cursor control device.

(Prior technology) The conventional cursor control method for the display is a one-sided cursor key system and a joystick system.

Various methods have been proposed, such as a digitizer method and a mouse method.

(Problems to be Solved by the Invention) However, all of the conventional control methods described above have advantages and disadvantages, and there is no definitive method to determine which one is the best. For example, in the case of a one-sided cursor key, although the cost is low, the directions of movement are limited, making it difficult to use on a graphic display. In addition, the joystick method allows for freedom in the direction of movement, but has problems such as high cost and the need to delicately move the wrist to move the cursor. Furthermore, in the digitizer method, there is an input pen.

There is a problem in that the degree of fatigue is high because the coordinate indicating means called a cursor or the like must be moved left, right, up and down. The mouse method has problems such as the need to provide a certain area near the operator for moving the mouse.

(Means for Solving the Problems) Accordingly, in the present invention, a coordinate input board, an instruction means for indicating desired coordinates on the coordinate input board, a switch means, and a display device for displaying nine characters, one figure, etc. A cursor position control means for controlling the cursor position of the display device is used, a cursor control area is provided on the coordinate input panel, and two operation modes are set in the cursor position control means, which are selected by operating the switch means. , in the first operation mode, the cursor is moved to a position corresponding to the designated coordinates by associating all or part of the cursor control area with the entire display area of the display device, and the second operation In the mode, based on the coordinates of two points designated within the cursor control area, the cursor of the display device is moved in the direction determined by the coordinates of the two points by a predetermined distance corresponding to the distance between the coordinates of the two points. The structure is as follows.

(Function) That is, in the present invention, the cursor control area on the coordinate input panel is switched between two operation modes by means of a switch, and in the first operation mode (- even if the cursor is displayed at a misaligned position, Instantly moves the cursor to or near the position, and in the second operation mode, moves the cursor a predetermined distance corresponding to the distance from the currently displayed position in the direction in which the input pen, etc. is slid. .

FIG. 2 shows details of the input pen 16. In the figure, 31 and 32 are barrels formed of cylindrical metal pipes, 33 is a conical base made of metal material, and 34 is a tail plug also formed in a truncated cone shape, as shown in the figure. The input pen 16 is screwed together to form a housing of the input pen 16. Reference numeral 35 denotes a circular through hole bored in the base 33, and an insulating coating 36 made of synthetic resin is applied to the inner surface of the hole.

A detection conductor 37 is formed by processing a circular metal rod, and is slidably inserted into the through hole 35. A donut-shaped iron suction plate 38 is fitted and fixed on the barrel 31 side of the detection conductor 37, and this is attached to the barrel 31 of the base 36.
By being attracted by a donut-shaped magnet 39 fixed to one end surface, the detection conductor 37 is urged such that its tip 40 protrudes outward.

Reference numeral 41 denotes a metal support plate which has a donut shape and is screwed and fixed to the inside of the barrel 31.

42 is a pressure-sensitive conductive rubber, which also has a donut shape.

One end surface thereof is fixed to a support plate 41, the other end surface is coated with synthetic resin 43, and one annular conductor 44 is embedded therein. 45 is the connection cable and the tail plug 34
The shielded wire 47 is inserted into the housing of the input pen 16 through the insertion hole 46 of the first core wire 4.

In the figure, 67 is a cursor control area. It should be noted that other required key areas are provided on this board surface, but illustration thereof is omitted. When the pen tip 40 of the input ben 16 comes into contact with the desired coordinates on this board surface, the detection conductor 37 slides toward the inside of the pen as described above, and the suction plate 38 moves against the pressure sensitive rubber 42.
By pressing , the resistance R between the annular conductor 44 and the barrel 31 becomes smaller.

The coordinate input panel 15 has a built-in control circuit (not shown), which detects the resistance value R at predetermined time intervals, and when the resistance value R becomes equal to or less than the predetermined value Ra, the input ben 16 comes into contact (hereinafter referred to as "pentameter"). , Dx, Dy and the resistance value data R (oC pressing force PR) at that time are supplied to the CPU 11.

FIG. 4 shows a screen 71 and a cursor 72 of the CRT 24.

Displayed as a shape.

Furthermore, the CPU 11 inputs coordinate data Dx from the coordinate input panel 15 or in the process of executing an application program or the like.
+Dy, in the force to crane control subroutine executed in response to the resistance value data DR being supplied, CRTC
The cursor addresses Ax and Ay are supplied to 21. CRT
C21 stores these cursor addresses Ax and Ay in register N.
The cursor 72 is stored in X and NY, and the cursor 72 is displayed at the corresponding position from the next display timing.

If you want to move the cursor 72 over a large distance on the screen 71, use the cursor control area 61 as the CRT screen 71, and move the pen tip 40 to the desired position 1, for example, point P1 near the center of the area, using normal pen pressure PRC. come into contact with When this pen pressure is PRO, the coordinate input panel 150 control circuit starts the coordinate detection operation as described above, and first, the point P1 at this time is
Coordinate data of D x (Pl), D y (Pl)
And the resistance value Rc at this time is supplied to the CPU 11.

Thereafter, while the resistance value R is below the resistance value Ra, the coordinate data DX at that time,
Dy and resistance value data R are supplied to the CPU 11.

The CPU 11 receives the sent coordinate data DX + D.
y is stored in the RAM 13 and checked. When the coordinate data Dx and Dy represent coordinates within the cursor control area 61, a cursor control subroutine as shown in FIG. 5 is entered.

That is, in step S1, the variable E is set to 1 as an initial process.
shall be. This variable E represents the operating mode, where 1 is the first operating mode and 2 is the second operating mode. This variable E and subsequent variables and constants are RAMt 3 or RO
It is assumed that the information is stored or is being stored in M14.

When the variable E is generated, the program proceeds to step S2 and checks this variable E. Since we are still in the state where we have proceeded from step S1, the answer is "1" and we proceed to step S3. In this step S3, a cursor address for the touch point is determined in order to make the entire cursor control area 61 correspond to the entire CRT screen 71. In other words, coordinate input board 15°C
The upper left corner of the RT screen 72 is the X coordinate.

The origin of the X coordinate, and the X direction of the CRT screen 71 and the
Assuming that the number of dots in each direction is the same as the number of dots in the cursor control area 61, the point Pa at the upper left corner of the cursor control area 61 is at the origin of the addresses Ax and Ay of the cursor 72 on the CRT screen 71. Because it corresponds 2. By subtracting the coordinate data Dxo*Dyo of this point Pa from the coordinate data Dx+Dy of the bent touch point P at that time, the cursor addresses Ax and Ay corresponding to the bent touch point PK are obtained.

Therefore, if it is assumed that the point P1 is touched as described above, then the cursor address Ax(P
l ), Ay(P 1) as in step S3.

Ax(Pl)=Dx(P+)−Dx.

Ay(Pl)-Dy(Pl)Dy.

is required.

Then, proceeding to step S4, cpttii supplies the coordinate data Ax (Pl) and Ay (Pl) at this time to the CRTC 21.

The CRTC 21 receives this coordinate data Ax(P+
), Ay (P+) as cursor address register N
Store it in X, NY and 2 For example, until then it is CP.

From the next display timing, move the cursor 72 displayed at the address Ax (Pl), Ay (Pl) to the point cp1.
to be displayed.

Next, the process proceeds to step 85 to check the resistance value R1 at that time, that is, the magnitude of the pressing force PR at that time. Here, it is assumed that a predetermined resistance value Re, which is somewhat larger than the minimum resistance value Rd when the pen tip 40 is strongly pressed against the board surface, is set in advance. Assuming that the pressing force PRc remains unchanged.

The coordinate data Dx and Dy are input, and the process advances by a distance in step S7.

Here, it is checked whether or not the new coordinate data Dx, Dy is for the point P included in the cursor control area 61. In this embodiment, when the answer here is "no", that is, the pentagram has been touched in some other area, and the need to move the cursor is eliminated, and this subroutine is executed. Let's finish and return to the main routine.

On the other hand, if the answer is "No" in step S7,
Since the cursor control area 61 is still being touched, the process returns to step S2 and the same steps 82 to S7 are repeated. Therefore, if the cursor display position CP1 corresponding to the first pen touch point P1 is not near the desired position, move the cursor 72 within the screen 71 by sliding the pen tip 40 while applying the normal pressing force PRc. It can be moved to any part.

When the cursor 72 can be moved to the desired position using only this first operation mode, the penta can be moved directly to the required position in subsequent operations.

By doing so, this subroutine ends as described above.

On the other hand, when more precise position adjustment is required.

After applying a reasonably large pressing force PRd to the pen tip 40 at a point near the desired point 1, for example, the point P1 where the aforementioned point CPIK cursor 72 is located, so that its resistance value R becomes smaller than the resistance value Re. Once the pen tip 40 is separated from the board surface.

Then, if you want to move the cursor 72 at the point CP1 in a desired direction 1, for example in the direction of the arrow 73, by touching an appropriate point P2 with a normal pressing force PRc, the pen tip 40
in the direction of arrow 62 to a desired distance 5, for example to point P3.

Then, the CPU that had been repeating steps 82 to S7 until now
In step II, since the answer in step S5 is [<Rej, the process moves to step S11 and checks the contents of variable E representing the operating mode at that time. At this time, the variable E
is ste.

The answer is rl because it remains the same as "1" set in step S1.
J, therefore, in the next step S12, its contents are changed to “2
'', that is, after changing to the second operation mode, the process proceeds to step 15.

Here, it is checked whether the resistance value R is thicker than a predetermined value Ra, that is, whether the pen tip 40 is separated from the board surface. At this point, the answer becomes "yes" and the process proceeds to the next step S14.Here, when the aforementioned point P2 is touched and the resistance value R becomes smaller than Ra, the control circuit of the coordinate input panel 15 detects and supplies the corresponding point P2. The coordinate data Dx and Dy of the point P2 are taken in and are substituted into variables FX and py in the first step Psis.

Next, the process advances to step S6, and the next coordinate data Dx, D
y, that is, if the pen tip 40 is slightly advanced on the arrow 62 toward the point P3 at this point, new coordinate data DX indicating that point.

Import Dy here. And this data D
Check whether y is within the cursor control area 61. In this example, the answer is "yes" and the process returns to step S2.

Since "E=21" is set in step S12, the answer in step S2 is "2", and the process then proceeds to step S21. Here, the previous coordinate data is Fx
, Fy and the subsequent coordinate data D
The difference components Gx, Gy between the points on the arrow 62 that have moved to
Calculate.

The CPU 11 then proceeds to step S22.

Address of cursor 72 at that time A x p A 7
.

That is, in the example described here, the difference components Gx and Gy are added to the addresses Ax and Ay indicating the point CP1. Then, the process advances to step S25, where Dx, DyftF at this time
x, F y, and the process proceeds to step S4 where the new cursor addresses Ax, A
y is supplied to the CRTC21.

As a result, the cursor 72 moves from point CP1 to point CP3 by the number of dots that is 1/10 of the sliding of the pen tip 40 from point P2 to point P3.

If the pen tip 40 is further slid to point P3 with the same pressing force PRc, the CPU will move from S5 to S7 during this time.
S2. S21-S23. If the loop S4 is repeated and the cursor 72 is moved in the same direction as the pen tip 40 by a distance corresponding to the amount of movement, and the pen tip 40 is stopped at one point P5, then the cursor 72 is moved to the point CP3. indicate. Note that if the amount of movement is insufficient, the bend touching to an appropriate point and sliding in the desired direction are repeated.

Once the cursor 72 has been moved to a desired position in the second operation mode in this manner, the user moves on to the operation of the main program currently being executed and touches a desired point outside the cursor control area 61.

As a result, the answer is "no" in step S7, and the CPU
11 exits from this subroutine and returns to the main program.

If you want to switch from the second operation mode to the first operation mode, touch the pen tip 40 at the desired position.
Apply the above-mentioned ``certainly large pressing force PRd.'' As a result, the answer in step S5 becomes ``R<ReJ'', the answer in step S11 becomes ``2'', and the variable E is changed in step S31.
is set to ``11'', causing the CPU 11 to return to the 10th operation mode.

(Other Embodiments) In this embodiment, the operation mode (variable E) is changed by applying a pressing force PRd to the pen tip 40. Penta to the function area set at the position,
The operation mode (variable E) may be changed depending on the change. In this case, for example, step S5 may be changed to ``Was the mode changeover switch operated?'' ” [If yes - 1, proceed to step S11; if “no”, proceed to step S6, and so on.

Next, in this embodiment, the coefficient in step S22 is set to 1/1.
Although it is set to 0, this can of course be set arbitrarily.

Furthermore, in this embodiment, there is a first operation mode and a second operation mode.

It doesn't matter if you stay there. In this case, the size of the area in step S7 will be changed depending on the operation mode.

(Effects of the Invention) As explained above, according to the present invention, the cursor can be freely moved large or small with a small amount of movement of one wrist, improving operability and reducing fatigue compared to conventional ones. can be achieved.
