Abstract

PURPOSE:To improve its operability by utilizing a digitizer as a setting means of a moving direction and a moving speed of a mark such as a cursor mark, etc. CONSTITUTION:When a tip 6 of an input pen 5 touches an input surface 4, a coordinate value of a touched point is sent out to a processing device 2 from a digitizer 1. When the processing device 2 receives this coordinate value information, and detects a fact that its coordinate value is a coordinate in a circle 7, an executing routine of movement control of a cursor mark on a display device 3 is executed. For instance, when the shift quantities of an (x) coordinate and a (y) coordinate of the cursor mark are denoted as X and Y, respectively, the shift is executed by adding X and Y to the coordinate value on display data of the cursor mark in case of the previous scan.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for controlling the movement of a mark such as a cursor mark using a digitizer.

[Prior art]

Examples of means for controlling the movement of marks such as cursor marks on the display surface of a display device include a joystick, a track pole, and a Mighty Mouse.

These devices detect the direction and angle of the tilt of the lever or the direction and angle of rotation of the pole, and move the cursor mark, etc. on the display surface of the display device in a direction and speed according to these directions and angles. It is something that makes you

Marks such as cursor marks can also be moved using the cursor keys on the keyboard, but
They can only move in a certain direction at a predetermined speed, and joysticks, trunk balls, mighty robots, and the like have better functionality.

When using a joystick, track pole, Mighty Mouse, etc., K-th hardware is naturally required to control movement. For example, in the case of a joystick,
A lever that operates to determine the direction and speed of movement,
This is a detector that detects the inclination of a lever. Therefore, there is a drawback that a large space is required for these pieces of hardware. Furthermore, when joysticks, Mighty Mouse, etc. are arranged on a desk, it becomes cluttered and troublesome. In addition, it is preferable that the input means used also be used as a movement control means.

When a digitizer is used as an input device, the digitizer is sometimes used as a means for moving marks such as cursor marks. The coordinates on the digitizer and the coordinates on the display surface of the display device ′j! r: 1 to I
When responding and operating the input pen, the user moves the input pen to a point on the digitizer corresponding to the position of the cursor mark while looking at the display so that the cursor mark moves to the desired position. This method is advantageous in terms of space because there is no space dedicated to movement control, but since the cursor mark moves 1 tvc to the target position, K points the input pen at a point on the digitizer corresponding to the target position. It has to be moved, which is prone to errors, and f
In addition, it is necessary to carefully control the position of the input pen, which poses a problem in terms of operability.

[Summary of the invention]

This invention allows the digitizer to be used as a movement control means by also using the digitizer as a means for setting the moving direction and speed of a mark such as a cursor mark when the digitizer is used as an input means.
It is rC thing. Hereinafter, the present invention will be explained in detail with reference to the drawings.

[Embodiments of the invention]

FIG. 1 is a diagram for explaining one embodiment of the present invention. In this figure, 1 is a digitizer, which is connected to a processing device 2. The processing device 2 is a device having calculation and processing functions such as a personal computer having a display device 3.

4 is an input surface of the digitizer 1, and 5 is an input pen for inputting coordinates in row 5. When the tip 61 of the input pen 5 is touched on the input surface 4, the coordinate values of the touched point are sent from the digitizer 1 to the processing device *2.

Circle 7 indicates the area for performing the movement system #.

FIG. 2 is an enlarged view of the area around circle 7.

As shown in Figure 2, circle 7 is used as a guide for directional force.
A line 8 is drawn from the center O in the medial direction. A diameter of 2 to 40 m is sufficient for the size of the circle 7.

Next, the processing procedure will be explained.

When the tip 6 of the input pen 5 touches a circle 7σ) at any point AK, the digitizer 1 detects the position #(X,) of point A.

ya) is sent out. The processing device 2 manages the coordinate values sent out from the digitizer 1, and when the receiver detects that the received coordinate values are the coordinates Q) within the circle 7, the cursor on the display device 13 is Enters a routine that controls the movement of marks.

Lask scan or line sequential scan! 17)
When moving a cursor mark on a CRT or liquid crystal display, the coordinate values of the cursor mark on display data are shifted every time one frame or one field is scanned.

Let the X and Y coordinate force shift amounts of the cursor mark be X and Y, respectively. Shifting is performed by adding the coordinate values KX and Y on the display data of the cursor mark during the previous scan R.

In one embodiment of the invention, input point A within circle 7.
coordinates (X@r ya ) and the On coordinates of the center of circle 7 (X@r ya )
X and Y are determined from equation (1) from l yo ).

This calculation is performed by the processing device 2VC.

Here, k-work and ky are constants.

If kx=>0, the direction in which the cursor mark moves matches the direction from the center O of the circle 7 to the point A, and the moving speed is equal to the line segment O.
It is proportional to the length of A.

FIG. 3 is a k-th diagram illustrating another embodiment of the present invention. In this figure, 9 is a circle with radius r, and circles 7 and 9 are concentric circles. The equation of circle 9 is expressed by equation (2).

(X x6)”+(y)J))”=r2 ・=-”-
= (21 Between yen 7 and circle 9, there is a line 10 in the middle diameter direction that serves as a guide for the direction. In the case of Fig. 3 as well, the cursor mark is moved to a point within circle 7. Touch the tip 6 of the input pen 5 to input the coordinates of that point.

Let the point touched by the input pen 5 be a point B. The digitizer 1 sends out point Bn coordinates (xb, yb).The processing device 2 uses the coordinates of the center 0 (Xo+y- and the coordinates of the receiving point B (Xbl yb) to form the equation of the straight line OB. Formula %) and Xr + which is the solution of simultaneous equations L0I) of formula (2)
'! Add r. xr*Yr is expressed by equation (3).

・・・・・・・・・・・・・・・(3) Straight line OB and circle 9
If the force intersection point is R, the intersection point Rσ) coordinates are (Xr + y

Next, the processing device 2 compares xl, +y with r2, and when xb2+y♂≧r2, determines X, Y(l-) using the following equation.

The signs of T, -K L, X rr Yr are fI
The same code as Xbl yb is selected n. IL

If you shift by adding n X and Y represented by
The movement of the cursor mark is as follows.

(11) When the tip 6 of the manual pen 5 touches the circle 9 (when the point B is within the circle 9), the cursor mark does not move.

(2) When the tip 6 of the input ben 5 touches the area between circles 7 and 9 (when point B is between circles 1 and 9),
In formula (4)! ＝に、＞。

If j, the direction of movement of the cursor mark is from center 0 to point B, and the speed of movement is proportional to the length of line segment RB.

In the case of this embodiment, processing of coordinate values is complicated, but it is effective for moving the cursor mark only outside the 1 circle B force, and has the advantage that the cursor can be easily controlled in the area near circle 9. .

The above description shows the case where the moving speed of the cursor mark is proportional to the length of the line segment between the input point and the reference point (1), but it is also possible to provide non-llf linearity. for example,
When using the movement direction control area shown in Figure 2, the following (
6) Calculate X and Y using any one of equations (n) to (9).

When controlling the movement of the cursor mark using these equations, kx=>0 ↑Aj, then the autonomous movement of the cursor mark is in the direction seen from the center 0 to the input point AY. Furthermore, the speed of movement increases as the length of the line segment OAn increases, and if the point A is near the center 0, the cursor mark can be moved extremely slowly. 74 &), it is easy to control the cursor mark when point A is near the center On.

Note that when formulas (6) and (7) are used, the moving speed of the cursor mark is equal if the lengths of the line segments OA are equal, regardless of the direction of the line segments OA.

The circle 1 in FIG. 2 may be replaced with a square Ki & as in FIG. 4 f) square 11fl. At this time, when the processing device 2 detects that the tip 6 of the input wall 15 is within the square 11, it enters a routine for controlling the movement of the cursor mark. The values of X and Y are determined by equations (1), (6) to (9), etc., as in the case of the second gravity.

The circle 9 in Figure 3 is also a square 12 as shown in Figure 5.
You can also replace it with a rectangle such as In Figure 5, squares 11 and 12 have a common center 0 (Xo + "Io)
' to have. Let the length of the diagonal of square 12 be 21.

Also, point C (Xc+y6
) K person shall touch the tip 6 of the cube 5. In this case, X and Y are determined by the compensation processing device 2Vc based on equation (10).

k, and Xs + 3's are the X coordinate and the doesn't move. When point C is between squares 11 and 12, kx=>.

Then, the direction in which the cursor mark moves is from the center 0 toward the point CK, and the speed in which the cursor mark moves is proportional to the length of the line segment OC.

In the case of Figures 3 and 5, the speed at which the cursor moves like the case of Figures 2 and 4):! -ke, line segment 0B
f7. : can be expressed as a non-linear function of the length of OC.

In the above, when the tip 6 of the input ben 5 is touched within the movement direction control area of the cursor mark, the processing device 2
It was explained that the movement of the cursor mark is automatically controlled, but if a function key is provided, and when the function key is pressed, the processing unit f2 will control the movement of the cursor mark. Of course, it is also possible to enter a routine to be executed.

Although the object to be moved L1 is a cursor mark, it may be any other figure, mark, etc.

Furthermore, although the input surface 4 of the digitizer 1 may be opaque, it can be handled in exactly the same way even if it is transparent.

If the input surface 4 is transparent, the display device 13
It can also be used by lying on the display surface of the KN. Below, we will discuss the case where movement is controlled by a touch panel configured by overlapping a transparent input surface of a digitizer on a display device. FIG. 6 is a diagram showing an example of a touch panel.

In this figure, 13 is a digitizer, which has a transparent input surface 14. A display device 15 includes a display surface 16. The digitizer 13 and the display device t15 are actually stacked closely together. 17 is a processing device that manages the coordinate values received from the digitizer 13, performs processing such as arithmetic operations, and processes for displaying them on the display device 15. For example, when a line 1B is written on the input surface 14 of the digitizer 13 with the input pen 5, the processing device 117 converts the coordinate values received from the digitizer 13 into display data when writing the line 18. A position fK line 19 is displayed on the display surface 16 of the display device 15 corresponding to the writing position on the input surface 14. When viewed from above, the displayed f'Ik line 19 coincides with the position of the drawn line 1B. This tile, digitizer 1
3 upper VC leaves no dark trace, but display device t1
It looks like 5 upper Vc training k. The rope can also be used as a vaporless force figure input device. This device t is called a touch panel, and can be used for a wide variety of other purposes such as display selection input. A display device 3 may be connected to the processing device 17 in addition to the display device #15.

In such a device, a mark such as a cursor mark is displayed on the display surface 16 of the display device 15, and when it becomes necessary to move the mark, it is displayed on the display surface 16, for example, in a graphic 201 as shown in the figure.

When the graphic 20 is viewed from above the transparent input surface 14, it looks the same as in FIG. For this reason, if the position corresponding to the figure 20Vc on the transparent input surface 14 is set as the movement direction control area, the same movement control as explained using FIG. 2 can be performed. In addition, if the figures shown in FIGS. 3 to 5 are displayed on the display surface 16 and the movement direction control area corresponding to these figures is set on the input surface 14, these figures can be used to The same movement control as K described above can be performed.

Figures such as circles 7 and 9 and squares 11 and 12 in Figures 2 to 5 may be displayed on the display surface 16 at all times, but when it becomes necessary to perform movement control, pressing the function key It may also be displayed by

The area for controlling the movement direction on the input surface 14 of the digitizer 13 can be set on the display surface 16 of the display device 15.
This is done only on tiles and six.

To set the movement direction control area only when necessary,
The entire surface of the input surface 14 of the digitizer 13 is
It can be used for its original purpose as 3.

Marks such as cursor marks that are subject to movement control are not connected to the display device 15 but to the processing device 11.
f, - It's a n 几 mark displayed on other nice play devices and it's annoying.

The area used for movement control is circle 7. Although shown as a square 11, the entire surface of the digitizer 13 may be used for movement control. For this reason, K is provided with a function key on the digitizer, and by pressing the function key, it is possible to switch between using it as a digitizer and using it as a movement control device. In this case, there is no need to touch the input pen 5 to determine whether or not the point L is in the movement direction control area, and there is an advantage that the processing by the processing device 2 or 17 becomes easier. Note that it goes without saying that the digitizer can also be used exclusively for movement control.

[Effect of F18in] As explained in detail above, the first invention of the present invention is to provide a movement direction control area on the input surface of the digitizer, input coordinates with an input pen inside this force, , when displaying a definite frame or field on a display device, a value based on the difference between the coordinates of the input point and the coordinates of a specific point within the movement direction control area should be moved on the display surface of the display device. The mark is moved by adding it to the coordinate value on the display data of the mark. With 14 (n), there is no need to prepare any other hardware for movement control, and the hardware 9 air configuration is simple and the space can be saved. The TRX has the effect of reducing the number of small blades on the desk, and the space on the desk can be used effectively.

1. According to this invention: (The invention of number 1 provides a small area within the movement direction control area, and 20) prevents the mark from moving within the small area.7. HO) has the advantage of being extremely easy to operate. Furthermore, when a part of the area of the digitizer is used as a movement direction control area, there is an advantage that most of the area of the digitizer can be used for the original function of the digitizer.

In addition, compared to the conventional method of moving the cursor mark by making a one-to-one correspondence between the tag position and the position on the Nice Play device, in this invention, the cursor moves while the input pen is stopped. It has the advantage of being easy to use.

The second and fourth inventions are constructed by connecting a transparent digitizer and a nice play device lt, and use a Tsuchibanel, so movement control and) Display and set the movement direction control area only when you need it (other times, the advantage is that you can use the entire area for the digitizer's original functions, completely unrelated to movement control). There is.
