Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an information display device, and particularly to an information display device having a screen scrolling function.

[Prior Art] In conventional integrated software for information display devices such as personal computers, screen scrolling is instructed by clicking a scroll bar on the screen with a mouse cursor.

[Problems to be Solved by the Invention] However, in the conventional example described above, the directions of the scroll bar are limited to up, down, left, and right, and it is impossible to specify diagonal directions or the like. Furthermore, there were only three scroll display speed levels, such as "one line movement display", "next page screen display", and "data area end display".

Furthermore, only the "one line moving display" allows continuous scrolling by holding down the mouse button, and the other two scrolls usually only scroll once with one click. As described above, in the past, it was not possible to arbitrarily select the scrolling direction, nor was it possible to steplessly select the scrolling speed.

On the other hand, it has been possible to instruct scrolling using a joystick, but the joystick only has directions up, down, left and right, and the speed can also be set to either "ON" or "OFF".
It was customary to have only two stages. In this case as well, stepless selection of scroll direction and scroll speed is not possible.

The present invention eliminates the above-mentioned conventional drawbacks and provides an information display device in which the scrolling direction and scrolling speed can be selected steplessly.

Furthermore, the present invention provides an information display device that allows easy instruction operations.

[Means for Solving the Problem] In order to solve this problem, the information display device of the present invention has the following features:
An information display device capable of screen scrolling includes an input means for inputting the direction and distance of a touch position from a reference position, and a scroll direction and scroll speed corresponding to the direction and distance input from the input means. scroll setting means for setting the scroll setting means; and scroll execution means for scrolling in the direction at the speed set by the scroll setting means.

Furthermore, the input means is a touch panel, and tactile markings are provided on the touch panel.

[Operation] In this configuration, the scroll setting means sets the scroll direction and scroll speed in accordance with the direction and distance input from the input means, and by performing scrolling according to the set values, stepless scrolling is achieved. Scroll by direction and scroll speed.

[Example] The information display device of this example will be described below with reference to the accompanying drawings. In this example, an information display device of a personal computer (hereinafter referred to as a personal computer) will be explained as an example.

FIG. 1 is a schematic block diagram of a personal computer according to this embodiment.

1 is a central processing unit (hereinafter referred to as
(hereinafter referred to as a CPU), 2 is a memory that stores the execution program of the CPU 1, and also includes a random access memory (hereinafter referred to as a RAM) 2a that can be used for auxiliary storage and a video RAM.
(hereinafter referred to as VRAM')) 2b. VR
AM2b is used for displaying on the CRT display 3. A transparent touch panel 4 is installed to cover the CRT display 3, and the user can specify a specific position on the CRT display 3 by touching the touch panel 4.

5 is a keyboard for inputting character strings, and 6 is a scrolling touch panel for instructing the scrolling direction and scrolling speed of the screen display on the CRT display 3.

The keyboard 5 and the scrolling touch panel 6 are combined and integrated.

This is because the scrolling touch panel 6 is lightweight, and this is to prevent it from moving just by being touched by the user. 7 is an external storage device that stores various programs and a large amount of data, and 8 is a printer for printing output.

FIG. 2 is a general view of the keyboard 5 and the scrolling touch panel 6 in an integrated state.

FIG. 3 is a detailed view of the scrolling touch panel 6 when viewed from above; from the center of the scrolling touch panel 6,
Four concentric circles 6a are drawn, and straight lines 6b are drawn in eight directions from the center.
It's growing.

FIG. 4 is a diagram showing a state in which the concentric circles and straight lines in FIG. 3 are embossed on the surface of the scrolling touch panel 6.

This line marking makes it possible to see which position on the scrolling touch panel 6 the user is touching. Note that the scrolling touch panel 6 has a slightly lower sensitivity, so that it does not respond to a light touch by the user, and is only touched when the user presses it a little harder after checking the position by feeling around concentric circles or straight lines. There is a mechanism for determining whether Of course, if the user moves his/her finger while pressing the scrolling touch panel 6, the scrolling direction and scrolling speed can be continuously changed.

As the scrolling touch panel 6, a device in which piezoelectric elements are arranged two-dimensionally (for example, in the X-axis, Y-axis direction, or in the circumferential direction of one radius) and scans the piezoelectric elements is used, but is not limited to the following. - For example, the scroll speed is approximately the same as scrolling to the next screen on the outermost concentric circle,
Outside the area, the end of the area is displayed, and inside the area is scrolled in proportion to the distance from the center position.

FIG. 5 is a schematic diagram in which arrows 10 indicating the user's button position 9, scrolling direction, and scrolling speed are overwritten on the scrolling touch panel 6. However, the "e" mark and arrow 10 indicating the bushing position 9 are not actually displayed. Note that the scroll direction and scroll speed are calculated as follows. The center position of the scrolling touch panel is set to coordinates (0, O), the radius of the outer concentric circle is set to r=10, and the coordinates of button position 9 are set to (x, y).
), then θ=tan-'(y
/x): Here, if y≧0, O≦θ≦π, if y<o, π<θ×2π is memorized, and the scroll speed is r=
x+y" value is stored.

If θ=0, scroll to the right, if θ=π/2, scroll to the top, if θ=π, scroll to the left, θ=3
π/2 indicates scrolling downward. Of course, it can also represent diagonal directions and scrolling. On the other hand, the scroll amount is r
If the value of =, rnu111-ygo is "10", it will scroll to the next screen in approximately 2 seconds, if it is "0", there will be no scrolling, and if it is "5" below, it will take half that time, 4 seconds. Scrolls at a speed corresponding to that number, like scrolling to the next screen. Here, the elements are arranged on the xy-axis plane, but if they are arranged on the rθ (radius, angle) plane, "θ" is the scroll direction and "r" is the scroll speed.
However, the structure of the scrolling touch panel becomes complicated. Furthermore, various considerations may be made regarding the relationship between the above-mentioned touch position and scroll amount.

For example, assuming that the amount of scrolling is determined by how many lines of the display area are moved during repeated scanning of the screen display, suppose that one screen scan is every 5 milliseconds, and the horizontal
For a display screen of 400 vertical dots, if the scroll amount value is "5", the screen will be scrolled by 1 dot every 2 scans, and if the scroll amount value is "10", it will be scrolled by 1 dot every 1 scans. You can make it scroll by a dot. Also, the number of moving scans may be constant, such as scrolling 5 dots every 10 scans when the value is "5", and 10 dots every 10 scans when the value is "10". teeth,
In the case of "10", a screen scrolled by 400 dots every 1 second may be displayed after 1 second by 800 dots.

FIG. 6 is an example of a screen display on the CRT display 3. Reference numeral 11 indicates a screen frame, 12 indicates a data display screen, and 13 indicates various function menus for creating data. The data display screen 12 is the area to be scrolled.

Note that the function menu 13 has no direct relationship with scroll display, so a detailed explanation will be omitted.

FIGS. 7A to 7D are diagrams for explaining how to use the VRAM 2b to perform scroll display at high speed.

FIG. 7A shows a state in which the data display screen 12 on the CRT display 3 is stationary.

Reference numeral 20 indicates the entire area in which data is expanded on the VRAM 2b, and 21 indicates a screen display area actually displayed on the data display screen 12.

Normally, scrolling means that the VRAM area 20
This refers to the movement of the screen display area 21 within the . If it is within this range, the data has already been expanded, so scrolling is displayed immediately and at high speed.

FIG. 7B shows that the user continues to touch the scrolling touch panel 6 to instruct diagonally upward scrolling, and finally
This shows a state in which the screen display area 21 has reached the upper left end of the RAM area 20. At this point, the user is still requesting diagonally upward scrolling, so it is necessary to expand the data further diagonally upward. Therefore, first, image data near the screen area 21 in FIG. 7B is stored in the VRAM area 20.
At the same time as projecting to the symmetrical position above, other old development data will be deleted. This results in the state shown in FIG. 7C. Of course, since the hail frame is also moving in the screen display area 21 at the same time, the display on the data display screen 12 does not change during this work.

Then, the data is expanded into the blank area shown in FIG. 7C, resulting in the state shown in FIG. 7D. This allows the user to continue scrolling diagonally upward at high speed.

Next, the scrolling operation of the personal computer of this embodiment will be explained according to the flowchart shown in FIG. FIG. 8 shows a subroutine that this device calls when the user detects a touch on the scrolling touch panel 6.

In step S1, the user selects the scrolling touch panel 6.
It is determined whether the is touched, and if "No", the process returns from this subroutine.

If it is touched, move to step S2 and touch position 9.
The x and y coordinates of the touch position 9 are measured, and the scroll direction and scroll amount are calculated from the coordinates of the touch position 9 in step S3.

Here, the scroll amount is the number of dots moved from the currently displayed screen to determine how many dots have moved from the screen to be redisplayed. If the scroll amount is large, the scroll speed is large.Next, in step S4, the VR
The screen display area 21 on the AM area 20 is moved in the scroll direction by the scroll amount and displayed on the data display screen 12.

In step S5, the screen display area 21 is the VRAM area 2.
It is determined whether the end of 0 has been reached, and if the end has not been reached, the program returns to the beginning and the processing from step Sl is repeated. If it has been reached, the process moves to step S6, and the screen display area 21
The surrounding image data is moved to a point symmetrical position on the VRAM area 20, and old expanded data is cleared.

Next, in step S7, the data is developed in the blank area on the VRAM area 20, and then the program returns to the beginning and the processing from step S1 is repeated.

In this embodiment, the scrolling touch panel was used to instruct the screen scrolling direction and scrolling speed, but the scrolling touch panel was used to instruct the screen scrolling direction and scrolling speed.

Regarding the movement of the drawing cursor, etc., the direction and speed of movement can be instructed using the touch panel of this embodiment.

As explained above, when scrolling the screen on a personal computer or workstation, the user can instruct the scrolling direction and scrolling speed using the touch panel, which has the effect of allowing the scrolling direction and scrolling speed to be set steplessly. Furthermore, since the scrolling touch panel is inscribed with lines, the user can tactilely know the touch position on the touch panel.

[Effects of the Invention] According to the present invention, it is possible to provide an information display device that scrolls the screen by setting the scroll direction and scroll speed steplessly. Furthermore, it is possible to provide an information display device with easy instruction operations.
