Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a character string display method for moving and displaying character strings on a display device.

[Technical disadvantages of inventions and their problems]

To move the string displayed on the display device,
A method is adopted in which this character string is moved from the current display position to the rightmost display position (horizontally) or from the current display position to the lowermost 1Mt upper end (vertically). In this method, when moving an entire character string, this character string is always moved as one in the horizontal direction and in the overlapping direction, and only one character is moved along an arbitrary path with vertical lines or corners. Therefore, it was impossible to give a character string a moving image quality and move the display.

For example, if a figure consisting of a block diagram and a route is displayed on the display device as shown in Fig. 5, and you want to explain how data flows along the route by moving the example letters ABCD (Fig. a).

After moving this entire character string horizontally to the right to the outside of the path (@Figure 5 (b)), moving this entire character string vertically in one direction directly below (Figure 5 (C)), horizontally to the left In other words, if you want to move and display the entire character string along an arbitrary path (this is the vertical direction), the character string will be moved and displayed by sequentially changing direction one character at a time, as shown in Figure 5. (b) As shown in (c), the entire character string had to be moved, so it was not possible to give the characters a moving image like animation.Also, in this case, the 1c display screen l %Assuming the movement of the entire character string shown in Figure 5(b), a margin display screen for the length of the character string must be provided on the right outside of the route.Therefore, the user must move the entire character string as shown in Figure 5(d). It is not possible to create a figure like the one shown in Fig. 2, and it is necessary to create the figure while taking the margins of the display screen into consideration.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a character string display method in which a character string is displayed moving along a path on a display device in a manner similar to that of a moving image.

[Summary of the invention]

The present invention displays a character string along a moving route I on a display device by determining the locus of each point on a moving route consisting of horizontal lines and vertical lines. When the character string reaches a point), the direction of the character string is changed character by character across the bending point, and the character string is displayed so as to follow the route. Also, in order to make the arrangement order of the character strings the same at the movement start point and movement end point, if the order of the character strings is reversed during the movement path (for example, the character string moves from right to bottom to left) ), an adjustment path is automatically generated at one bending point, and the character strings are moved and displayed while maintaining the correct arrangement order.

〔Effect of the invention〕

According to the present invention, by moving and displaying character strings along a route in an animated manner, it is possible to display convincingly as various explanation screens. ``Moreover, it has tremendous practical advantages, such as maintaining the correct order of character strings while moving along a route.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of an apparatus according to an embodiment of the present invention.

Character string information input by the user through the input device 1 is displayed on the display device 7 via the display control device 6.

In addition, when the user manually inputs the movement start point, movement end point, and bending point (direction change point) of the route he wants to move in response to the displayed character string, these coordinates are stored in the movement route knowledge storage device 2. Stored.

FIG. 2(a) is a diagram showing this storage format, which shows the movement start point (Xs, Ys), the bending point (Xi, Yi) (even if there are multiple bending points, there are five), the movement end point ( Xe.

Ye) is stored in the path i@ (in input order).

The direction test knowledge storage device 3 stores information on combinations of route directions in which a reversal of character string arrangement may occur in the format shown in FIG. 2(b).

For example, the moving direction of the route is (X positive) → (y positive) → (X negative)
If so, the direction is reversed in the positive and negative directions of X, so the character string arrangement is also reversed and an adjustment path is required (0),
If it is (X positive) → (y positive) → (X positive), the direction is not reversed, so there is no need as shown in FIG. 1, etc.

The direction inspection device 4 determines the direction from the coordinates of each point given to the moving route knowledge storage device 3.
Check whether the string arrangement is reversed by referring to . That is, (xI-Yt) (KS, Ys) (Xt,
Yt)-(X+, Yt), (Xe-Ye)-
(Xt, Yt) and compares the change in the direction of the route (for example, (X positive) → (y positive) → (X negative) with the direction inspection knowledge 3. (This route direction and increment are determined by display control. (It is also sent to the device t6.) The adjustment route generation device 5 generates an adjustment route to prevent the character string from reversing when it occurs according to the instruction from the direction inspection device 4, and writes it in the movement route knowledge 2 (about this will be described later).The display control device 6 moves the character string displayed on the display device 7 along the path w!rl using the moving route information@2. The route information (
30 steps in the X direction → +20 steps in the y direction → 130 steps in the X direction) Figure 3 is an operation flow diagram of the display control unit, and Figure 4 is a character string in the display device. A diagram showing how the columns are displayed moving (Figure 4 (a)
) to (d) are display diagrams when no adjustment path is generated, (e
) to (h) are display diagrams when an adjustment route is generated. The specific operation of this embodiment will be explained below using FIG. 3 and FIG. 8g4.

First, when a user inputs a desired character string from the input device 1, these are displayed on the display device 7 via the control section 6.

Next is the starting point and bending point of the travel path.

When the coordinates of the end point are input, the direction checking device 4 predicts the arrangement order of the character string at the movement end point as described above in response to instructions from the control section 6 (FIG. 3, 11).

(This prediction method will be described later.) Here, it is assumed that the order of the character strings is not reversed, and this fact is sent to the control unit 6 (FIG. 3, 12). Then, the control unit 6 sets the specified movement start point to the current display point of the character string (the position of the first character to be moved) (FIG. 3, 16).

Then, the coordinates of the current display point are calculated and a character string is displayed at the coordinates (FIG. 3, 19). (In addition, when moving a character string that is already displayed, the current display point and the movement start point coincide in most cases, so the step in FIG. 316 can be omitted). Then, update the current display point as shown in Figure 4 (a).
), the current display point's
0), that is, in the case of Fig. 4 (a), if the D position of %ABCD is the initial value of the current display point, the X coordinate of this D position (and C position, B position, A position) is incremented by +1. One character string “ABCD” is displayed in that position sequentially.
When the current display point (coordinates of the first character position in the direction of movement) of the sixth-order character string that moves to the right as a unit matches the bending point specified by the user (Fig. 3, 17).
c) When the route 1 is advanced by +30 steps in the
0 steps) to change the moving direction of the first character (Fig. 3, 18).In other words, the current display point from the bending point is updated because path 2 is in the positive direction of y. (+1) Subsequently, when the letters C, B, and A reach the bending point, the directions are changed in order. Therefore, Fig. 4(b) (C)
At the bending point shown in , the character string 'ABCD' is bent character by character, so it is possible to add a moving quality to the character string that causes it to crawl along a path.

After the bending point in Figure 4 (C), the X coordinate of the current display point is sequentially decremented by 1, so (130 steps in the X direction based on the route 3 information in Figure 2 (C)) the character string 'ABCD' moves to the left. Then, as shown in Figure 4(d), when the current display point of the first character matches the movement end point specified by Uniza, (
In other words, when the character string is moved 130 steps in the X direction), the movement of the character string ends (FIG. 3, 21).

In the case of the above route, as shown in FIGS. 4(a) and 4(d), the arrangement order (ABCD) of the letter U at the movement start point is different from the arrangement order (DCBA) at the movement end point.

The operation to make this match will be described.

First, when the direction checking device 4 detects that the arrangement of the character strings is reversed by the method described above, it notifies the control section 6 to that effect (FIG. 3, 12). Then, the control unit 6- adjusts the adjustment path 3 by the length of the character string from the bending point closest to the designated movement end point (that is, the bending point input just before the movement end point) (FIG. 4(e)). ′ is created. In other words, the bending point 'A
The most extreme coordinate of the adjustment path is determined by stepping the X coordinate by the length of BCD', and is set as +4 path 3' in the X direction (FIG. 3, 13).

Next, an adjustment path 4' is created in the opposite direction along the created adjustment path 3' to the bending point. In other words, create a -4 path 4' in the X direction.
', 4' (Fig. 3, 14). And this adjustment path 3
Add ', 4' to the movement route knowledge. In other words, in the example of FIG. 2(C), path 3' (X
direction, +4) and route 4' (X direction -4) are added, and the previous route 3 is changed to route 5, thereby updating the moving route (FIG. 3, 15).

When the string 'ABCD' reaches this inflection point,
(When the current display point coincides with the bending point) Change the direction in the positive direction of X to move to the adjustment path history sequentially from the first letter D) (Fig. 4 (e)), and move to the last letter A. (change direction to the negative direction of X) (Fig. 4 (g)).

Move to the movement end point in this arrangement order (13 in the X direction)
4 steps) (Figure 4(h)). When the reciprocating movement of the adjustment path is added in this way, the arrangement order of the character strings at the movement start point and movement end point becomes the same as shown in FIGS. 4(a) and 4(h).

As described above, according to the present invention, a character string can be displayed in an animated manner while bending character by character along a moving route, and there is no need to adjust the display area on the screen depending on the length of the character string. None. In particular, as shown in FIG. 5, when a character string is moved with respect to a line figure that is already displayed, it is easy to understand as an explanation screen. Furthermore, since the arrangement order of character strings can be maintained correctly at the start and end points, the practical advantages are enormous, such as being able to manipulate ζ without being aware that it is a character string.

Note that the present invention is not limited to the above embodiments. In the above embodiment, the adjustment path was provided at the bending point immediately before the movement end point, but if there are multiple bending points, it may be provided at other bending points. Furthermore, if the user is confused when the character string is displayed and moved on the adjustment path, the character string may be specified not to be displayed on the display only during that movement.

Further, when moving and displaying a character string, it is not necessary to update the current display point by +1, and for example, the current display point may be updated all at once from the movement start point to the bending point. Further, the moving route is not limited to the horizontal direction and the vertical direction, and may be an oblique direction, and the meridians do not necessarily intersect at right angles at the bending point.
