Abstract

PURPOSE:To speed up a scroll operation by determining the speed or quantity and the direction of a scroll by a distance for connecting a reference point and a cursor designated by a mouse, etc., and an angle made against a horizontal line. CONSTITUTION:The speed and quantity of the scroll are determined by a free distance between a reference point and a cursor, and the direction of the scroll is determined from an angle made by a straight line for connecting the reference point and the cursor and a line being horizontal to a screen. The figure (a) and the figure (b) are examples for showing the relation of distance (d) between the cursor and the reference point determined on the screen, and the speed V of the scroll, and the relation of an angle theta made by a straight line for connecting the cursor and the reference point and a line being horizontal to the screen, and a scroll direction phi. In the figure (b), theta and phi show 0 deg.-360 deg. counterclockwise. According to this constitution, the speed V of the scroll is an increase function of the distance, therefore, the scroll can be executed at high speed. Also, since the direction phi is also the increase function of the angle theta, the scroll direction can be controlled intuitively.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a scroll instruction method, and particularly to a scroll instruction method for changing the display position of a display figure in a computer terminal or workstation equipped with a position pointing device. .

[Conventional technology]

In this type of conventional scroll instruction method, a specific figure called a scroll icon on the screen is used as a position instruction device,
In other words, the display position is changed in a certain direction (hereinafter referred to as "scrolling") by detecting what is specified using a pointing device such as a mouse or joystay, and within an area called a scroll bar on the screen. There is a method of determining a target display position in correspondence with a point specified using a position pointing device.

In the former method using scroll icons, as shown in FIG. 11, scroll icons 1.1 to 14 representing four directions are often displayed at three corners of the screen, and the user can select the scroll icons 11 to 14. 14 is detected by the position pointing device, scrolling is performed in the corresponding direction by an amount proportional to the designated time. As an extension of this technology, scroll icons 11-1
A method in which the scrolling direction can be changed using a button attached to the position pointing device that is pressed when specifying 4. The latter method using a scrollper has scroll bars 22 and 21 displayed horizontally and vertically on the screen, as shown in FIG. is often displayed, and the end to end of the scroller 21.22 represents the entire displayable area of the object currently displayed on the screen. 0 Normal scroller 21.22
Inside, position indicating figures 23 and 24 corresponding to the position of the part currently displayed on the screen are drawn. Specify a certain position within the scroll bar or use the position indication figure 23.
24 within the scrollper 21.22 using the position pointing device, the corresponding position is displayed on the screen.

[Problem that the invention seeks to solve]

Among the conventional methods mentioned above, the method using scroll icons only detects information that the scroll icon has been designated, so the scrolling speed cannot be controlled, so it takes a long time if a large amount of scrolling is required. There are drawbacks. Furthermore, since the figures are located at separate positions on the screen without representing their respective directions, there is a drawback that changing the scrolling direction is troublesome.

The method of changing the scrolling direction using a button has the drawback that the installation position of the button attached to the position pointing device may not match the scrolling direction, and it is difficult to intuitively correspond to the direction.

Additionally, the scroller method has the disadvantage that if you want to scroll from one end of the viewable area to the other, you have to move the cursor from one end of the screen to the other, which requires large body movements. .

The present invention improves these shortcomings of the prior art and allows users to easily and intuitively adjust the scroll speed (speed and direction) with fewer operations.
The purpose of the present invention is to provide a scrolling method that can control the target display position.

[Means for solving problems]

The scroll instruction method of the present invention sets a reference point on the screen, calculates the distance Md between this reference point and the cursor specified by the user, and the angle θ formed by the reference point and the cursor position with respect to the horizontal direction of the screen. , the speed of scrolling or the amount of scrolling is determined by the distance @d, and the direction of scrolling is determined by the angle θ.

[Effect]

In the present invention, the free distance ld between the reference point and the cursor
Since the scrolling speed or scrolling amount is determined by , the scrolling speed or scrolling amount matches the body movement. Therefore, the speed or amount of scrolling can be intuitively controlled, and high-speed scrolling becomes possible. Furthermore, since the angle θ is directly reflected in the scroll direction, the scroll direction can be intuitively controlled and the scroll direction can be easily changed.

〔Example〕

Next, embodiments of the present invention will be described using FIGS. 1 to 10.

FIG. 1(a) is a graph showing an example of the relationship between the distance d between the cursor and a reference point set on the screen and the scrolling speed V, and FIG. 1(b) is a graph showing an example of the relationship between the cursor and the reference point set on the screen. 7 is a graph showing an example of the relationship between the angle θ formed by a straight line connecting a reference point with a line horizontal to the screen and the scroll direction φ. 1st
In Figure (b), θ and φ are expressed as 360° counterclockwise from Oo.

Since the scrolling speed V is also an increasing function of the distance d, the scrolling speed can be controlled intuitively. Since high-speed scrolling is possible, the target display position can be reached in a short time. Scroll direction.

Since φ is also an increasing function of the angle θ, the scroll direction can be controlled intuitively. It is also easy to change the scroll direction.

FIGS. 2 to 4 are graphs showing other examples of the relationship between the distance @d between the cursor and the reference point and the scroll speed V.

The line showing the relationship between the distance 119d and the scrolling speed V is
It does not necessarily have to be a straight line as shown in Figure 1(a),
Curves such as those shown in Figures 2 and 3 are also possible.In order to perform the scrolling operation intuitively, the distance d should be determined by the scrolling speed V.
It is preferable that it be an increasing function of .

FIG. 4 shows an example in which the scrolling speed is set to zero to prevent scrolling when the cursor is located within a distance δ from the reference point. By setting the distance δ near the reference point, the user can move the cursor near the reference point to check or correct the scrolling result.

FIG. 5 according to the distance Md between the cursor and the reference point.

As shown in FIG. 6, scroll Jim may be determined instead of scroll speed V. M in FIGS. 5 and 6
indicates the scroll amount corresponding to the distance to the displayable end of the displayed object.

By setting a large amount of increase in the scroll im with respect to the distance d, a large amount of scrolling can be performed with less physical movement, and the target display position can be reached in a short time.

FIG. 6 shows an example in which when the cursor is located within a distance δ from the reference point, the scroll amount is set to zero so that no scrolling is performed.

By setting the distance δ near the reference point, the user can move the cursor near the reference point to check and correct the scrolling results.

The line indicating the relationship between the distance 1llid and the scroll amount m does not necessarily have to be straight, but in order to perform the scroll operation intuitively, it is desirable that the scroll amount m be an increasing function with respect to the distance [d.

Furthermore, the relationship between the angle θ formed by the straight line connecting the cursor and the reference point with a line horizontal to the screen and the scroll direction φ is as follows:
It is not always necessary to have a proportional relationship as shown in FIG. 1(b). 7 to 9 are graphs showing other examples of the relationship between the angle θ and the scroll direction φ.

FIG. 7 shows an example in which scrolling is limited to only four directions: up, down, left, and right. FIG. 8 shows an example in which scrolling is limited in two directions, left and right, and FIG. 9 shows an example in which scrolling is limited in two directions, up and down.

These examples are effective for screens displaying characters or the like that do not require much free scrolling, since the scroll direction does not change unnecessarily.

Figure 10 shows the screen 0 when this scrolling method is applied.
This example shows a display example of the scroll figure 03 displayed in Figure 1. In this example, the scroll speed V was determined by the function shown in Figure 4, and the scroll angle θ was determined by the function shown in Figure 7. In this case, the scroll figure 03 is for clarifying the scroll direction. The radius of the non-school area 04 is δ in FIG. Reference point 0
The position of the scroll figure 03 including 2 may be fixed at a fixed position on the screen, or may be set to any position desired by the user.

〔Effect of the invention〕

As described above, with this method, it is possible to intuitively control the speed or amount of scrolling and control the scrolling direction, and it is possible to perform an easy and high-speed scrolling operation.
