Detailed ways

In order to improve the accuracy of cursor movement control on a touch-screen mobile communication terminal, the embodiment of the present invention provides a cursor control technology that controls cursor movement according to the sliding speed of the control body, so that the length of the moving distance matches the speed of the sliding speed. The specific method is as follows: As shown in Figure 2, it includes the following steps:

Step S201, capturing the sliding track and sliding time when the control body drags the cursor on the touch screen to move;

Step S202, determining the sliding speed of the control body according to the sliding trajectory and sliding time;

Step S203, determining the moving distance of the cursor on the touch screen according to the sliding speed;

Generally, the smaller the sliding speed of the control body is, the shorter the moving distance of the cursor is, and the larger the sliding speed of the control body is, the longer the moving distance of the cursor is. When the sliding speed is lower than the set threshold value, the cursor does not move. Of course, entertainment mode can also be set, when the sliding speed of the control body is higher, the moving distance of the control cursor is shorter, and the smaller the sliding speed of the control body is, the longer the moving distance of the control cursor is.

Step S204, controlling the cursor to move on the touch screen according to the moving distance and the label where the cursor was before moving.

The sliding track of the control body when dragging the cursor on the touch screen can be a straight line, a curve, or even a broken line. The technology of capturing the sliding track and sliding time of the control body is well known to those skilled in the art. Here Not described in detail.

After obtaining the sliding track and sliding time, in step S202, there are two ways to determine the sliding speed of the control body according to the sliding track and sliding time, refer to the sliding track shown in Figure 3, the first method of determining the sliding speed V As shown in formula 1:

V=L/T..........(1)

Among them, L is the total length of the sliding track, and T is the sliding time;

The second determination method of sliding velocity V is shown in formula 2:

V=D/T..........(2)

Among them, D is the linear distance between the sliding start point and the end point of the sliding track, and T is the sliding time;

Of course, those skilled in the art may use other methods, such as multiplying the cursor movement distance S by a certain ratio and dividing it by T to calculate V, etc., which will not be listed here.

As shown in Table 1 below, in the embodiment of the present invention, different speed ranges can be pre-divided according to empirical values, and the cursor movement amount can be set correspondingly for each speed range:

Table 1.

Series speed range Cursor movement amount S First level V≤V1 S1 second level V1<V≤V2 S2 third level V2<V≤V3 S3 ... ... ... nth level Vm<V≤Vn Sn

Among them: S, L and D have the same unit, and the number of levels n can be determined according to the number of labels on the touch screen. For example, if there are 3 labels, it is set to 3 levels. The cursor movement amount S1 corresponding to the first level can be set to 0, that is, when the sliding speed of the control body is less than or equal to the set threshold value V1, the cursor will not move. The amount of cursor movement Sn corresponding to the highest level is actually limited by the size of the touch screen. When moving in the width direction of the touch screen, Sn is the width of the touch screen minus the width of a label, that is to say, the longest moving distance of the cursor is the maximum distance from the touch screen. The label of the edge moves to the label of the other edge. The cursor has the same characteristics when it moves in the height direction of the touch screen, so the description will not be repeated.

According to different actual operation modes of the touch screen, the cursor can move only in the width direction, or only in the height direction, or both in the width direction and in the height direction. Since the sliding trajectory shown in Figure 3 cannot be consistent with the moving direction, the cursor movement distance can be determined according to the actual speed of the control body, or according to the components of the actual speed of the control body in different moving directions.

Taking the method of determining the moving distance of the cursor when it moves in the width direction of the touch screen as an example, there are three methods, as shown in Figure 4, assuming that the width direction of the touch screen is X, and the direction from the start point to the end point of the sliding track is regarded as the sliding speed V Direction, the first method specifically includes:

Determine the first velocity component Vx of the sliding velocity V in the width direction X of the touch screen. According to the corresponding horizontal movement amount set for different speed ranges, for example, S in Table 1 can be regarded as the horizontal movement amount set for the corresponding speed range. A horizontal movement amount corresponding to the velocity range where the velocity component Vx is located is determined as the horizontal movement distance when the control cursor moves in the width direction of the touch screen.

The second method specifically includes: directly determining the horizontal movement distance according to the sliding velocity V, that is, determining the horizontal movement amount corresponding to the speed range where the sliding velocity V is located as the horizontal movement distance of the cursor in the width direction of the touch screen.

The third method is essentially the same as the first method, as shown in Figure 4, specifically: the quotient of dividing the first distance component Dx of the linear distance D between the starting point and the end point of the sliding track in the width direction of the touch screen by the sliding time T It is determined as the horizontal sliding speed component, and according to the corresponding horizontal movement amount set for different speed ranges, the horizontal movement amount corresponding to the speed range where the horizontal sliding speed component is located is determined as the horizontal movement distance of the cursor in the width direction of the touch screen. In fact, the horizontal sliding velocity component and the velocity component have the same calculation result.

Similarly, when the cursor only moves in the height direction of the touch screen, the method of determining the moving distance of the cursor on the touch screen according to the sliding speed may also include corresponding three methods, still referring to FIG. 4:

The first type: determine the second velocity component Vy of the sliding speed in the height direction Y of the touch screen, according to the vertical movement amount set correspondingly for different speed ranges, for example, S in Table 1 can be regarded as the vertical movement amount set for the corresponding speed range , the vertical movement amount corresponding to the velocity range where the second velocity component Vy is located is determined as the movement distance when the control cursor moves in the height direction of the touch screen;

The second method: according to the movement amounts set corresponding to different speed ranges, the vertical movement amount corresponding to the speed range where the sliding speed V is located is determined as the vertical movement distance of the cursor in the height direction of the touch screen.

The third type: the quotient of dividing the linear distance D between the starting point and the end point of the sliding track on the height direction Y of the touch screen by the second distance component Dy divided by the sliding time is determined as the vertical sliding speed component; and according to the corresponding settings for different speed ranges For the vertical movement amount, the vertical movement amount corresponding to the velocity range where the vertical sliding velocity component is located is determined as the vertical movement distance of the cursor in the height direction of the touch screen.

Preferably, in Table 1, both the horizontal movement distance and the horizontal movement amount are in units of the number of labels, that is, corresponding to different speed ranges, the number of labels that the cursor should move from the current label is used to indicate where the cursor is before moving. The number of reference labels that need to be moved for the label to start. Then still referring to Figure 4, when the cursor moves in the width direction of the touch screen, according to the moving distance and the label where the cursor is before moving, controlling the cursor to move on the touch screen specifically includes:

Determine the horizontal projection direction of the direction from the starting point to the end point of the moving track in the width direction of the touch screen, that is, the Vx direction;

Determine the total number of labels on the side of the label along the Vx direction on the touch screen before the cursor moves;

When the total number of labels is greater than the number of reference labels indicated by the horizontal movement distance, move the cursor along the Vx direction, and the number of reference labels minus 1 label is included between the label after the movement and the label before the movement, otherwise move the cursor along the Vx direction to the tab located on the far edge of the touchscreen.

That is to say, if the total number of labels is greater than the number of reference labels indicated by the horizontal movement distance, the cursor is actually moved to the target label, and the number of labels between the target label and the label before moving is: the number of reference labels minus 1. If the total number of labels is equal to or less than the number of reference labels indicated by the horizontal movement distance, the cursor can only be moved to the edgemost label.

The movement control principle of the cursor in the height direction of the touch screen is the same, as shown in Figure 4, specifically:

Determine the vertical projection direction of the direction from the start point to the end point of the moving track in the height direction of the touch screen, namely Vy;

Determine the total number of labels on the side of the label along the Vy direction on the touch screen before the cursor moves;

When the total number of labels is greater than the number of reference labels indicated by the vertical movement distance, move the cursor along the Vy direction, and the number of reference labels minus 1 label is included between the label after the movement and the label before the movement; otherwise, move the cursor along the vertical projection direction Move to the tab located at the very edge of the touch screen.

If the units of the moving distance and moving amount are the same as D or L, the embodiment of the present invention also provides a cursor moving control method, which can first divide the horizontal moving distance or vertical moving distance by the integer part obtained by a cursor width, and determine it as The number of reference labels that the cursor needs to move from the label it was before moving, and then use the above principle to control.

In the embodiment of the present invention, if the moving distance is zero, that is, the moving amount is zero, the cursor may be controlled to remain still on the touch screen. Further, in order to achieve a better animation effect, the cursor can be controlled to bounce according to the moving speed, so that the cursor shakes with the control body. Specifically include: when the cursor moves in the width direction of the touch screen, move the cursor along the horizontal projection direction for the set first distance and then move back to the label where it was before moving; when the cursor moves in the height direction of the touch screen, move the cursor along the vertical projection direction After setting the first distance, move back to the label before the movement. The length of the first distance is less than the width of a label, and is determined according to the number of reference labels. The first distance becomes shorter as the number of reference labels decreases.

In the same principle, when the total number of labels is equal to or less than the number of reference labels, in order to obtain a better animation effect, when the cursor moves in the width direction of the touch screen, move the cursor along the horizontal projection direction to the label located at the edge of the touch screen , further move the cursor along the horizontal projection direction for the set first distance and then move it back to the label on the edge of the touch screen; when the cursor moves in the height direction of the touch screen, move the cursor along the vertical projection direction to the label on the edge of the touch screen Afterwards, move the cursor further along the horizontal projection direction for a set first distance and then move it back to the label on the edge of the touch screen. In this way, after the cursor reaches the edgemost label, it can also bounce on the touch screen wall.

The embodiment of the present invention also provides a touch screen cursor control device and a mobile communication terminal, including:

A unit used to capture the sliding track and sliding time of the control body when dragging the cursor on the touch screen;

A unit for determining the sliding velocity of the control body according to the sliding trajectory and sliding time;

A unit for determining the moving distance of the cursor on the touch screen according to the sliding speed;

The unit used to control the movement of the cursor on the touch screen according to the moving distance and the label where the cursor moved.

Apparently, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention.
