Below, the realization of each step of the embodiment of the present invention shown in FIG. 1 is described in more detail:

For step 101:

The acquiring the moving direction of the contact point may include:

Determine the initial position of the contact point;

determine the current location of the touchpoint;

The moving direction of the contact point is determined according to the initial position and the current position.

Wherein, the initial position of the contact point may refer to the position of the contact point on the display screen at the initial moment of the current cycle after the slider is selected; the current position of the contact point may refer to the position of the contact point at the current moment after the slider is selected. The position of the point on the display screen; the time length of the cycle in the actual application is not limited in the present invention, and can be set independently in the actual application; in addition, the initial moment of the first cycle can be the moment when the slider is selected.

Alternatively, the initial position of the contact point may refer to the position of the contact point on the display screen when the slider is selected; the current position of the contact point may refer to the position of the contact point on the display screen at the current moment after the slider is selected. Location;

Alternatively, the initial position of the contact point may refer to the position of the contact point on the display screen when the slider is selected, before the current time and at a time interval of a preset time length from the current time; the current position of the contact point may be Refers to the position of the contact point on the display screen at the current moment after the slider is selected; wherein, the specific value of the preset time length is not limited in the present invention, and can be set independently in practical applications.

Wherein, the current moment may be the execution moment of step 101 of the present invention.

In the embodiment of the present invention, the display screen may be a non-touch display screen or a touch display screen, which is not limited here. The contact point refers to the position on the display screen of the indication means that can be detected by the electronic device when the slider is selected and after it is selected. The indication methods that can be detected by the electronic device include, but are not limited to, a mouse, a finger touching a display screen, a stylus touching a display screen, and the like. For example, the contact point can be the position of the mouse on the display screen when the mouse selects the slider and after the slider is selected; behind the block, where the hand or stylus makes contact with the display; and so on.

Each pixel on the display screen can be recorded and positioned by means of coordinates. The initial position and current position of the contact point can also be recorded by the coordinates of the pixel corresponding to the position of the contact point. Further, the moving direction of the contact point can also be It may be determined or identified according to the coordinates of the initial position and the current position. How to establish the coordinate system of the plane to which the pixels on the display screen belong in practical application is not limited by the present invention.

For example, as shown in Figure 2A, assuming that the pixel in the lower left corner of the display is used as the coordinate origin O, the row of pixels at the bottom of the display constitutes the abscissa axis of the coordinate system (that is, the x-axis), and the pixel in the leftmost column of the display Points constitute the ordinate axis (y-axis) of the coordinate system; the slider and slide rail 210 are located on the right of the display screen, and the slide rail 210 is parallel to the y-axis. If the initial position of the contact point is assumed to be point A, the coordinates of point A is (1016,555), the current position of the contact point is point B, and the coordinates of point B are (980,666), then it is obvious that the moving direction of the contact point can be determined from point A (1016,555) to point B (980,666) , even the moving direction of the contact point can be directly identified by the coordinates of these two positions.

For step 102:

Wherein, said determining the moving direction of the slider on the slide rail according to the moving direction of the contact point may include:

Determine the direction component of the moving direction of the contact point on the slide rail, and use the direction of the direction component as the moving direction of the slider on the slide rail.

Still taking Figure 2A as an example, since the slide rail is parallel to the ordinate axis, and the moving direction of the contact point is point A (1016,555) pointing to the direction of point B (980,666), therefore, the moving direction of the contact point is The direction component on the slide rail is: the point C on the slide rail whose ordinate is 555 points to the direction of the point D on the slide rail whose ordinate is 666.

Wherein, the determining the moving rate of the slider according to the angle between the moving direction of the contact point and the sliding rail may include:

Determine the degrees of the first angle between the moving direction of the contact point and the slide rail; the two angles formed by the moving direction of the contact point and the slide rail are respectively the first included angle and the second included angle, The degrees of the first included angle are not greater than the degrees of the second included angle.

The moving speed of the slider is determined according to the degree of the first included angle, wherein the moving speed of the slider is inversely proportional to the degree of the first included angle.

In practical applications, the degree of the second included angle may also be determined, and the moving speed of the slider is determined according to the degree of the second included angle. At this time, the second included angle is proportional to the moving speed of the slider.

Wherein, since the range of degrees of the first included angle is [0,90], the tangent or sine of the first included angle is proportional to the degree of the first included angle, and the cotangent or cosine of the first included angle is proportional to the first included angle The degrees of the angles are inversely proportional. Therefore, in practical applications, instead of directly calculating the specific degrees of the first included angle, the degrees of the first included angle can be represented by the tangent, cotangent, sine or cosine of the first included angle. Wherein, the tangent, cotangent, sine or cosine of the first included angle can be calculated according to the coordinates of the initial position and the current position of the contact point. specific,

Take the tangent of the first included angle to characterize the degree of the first included angle as an example, as shown in Figure 2A, the moving direction of the contact point is point A (1016,555) pointing to the direction of point B (980,666), and the sliding rail Parallel to the ordinate axis, then the tangent of the first angle ∠E between the slide rail and the moving direction of the contact point = (1016-980)/(666-555);

Correspondingly, the moving speed of the slider can be determined according to the tangent of the first included angle, wherein the moving speed of the slider is inversely proportional to the tangent of the first included angle.

Among them, between the degree of the first included angle (or the tangent of the first included angle, or the cotangent of the first included angle, or the sine of the first included angle, or the cosine of the first included angle) and the moving rate of the slider The specific functional relationship of can be set independently in practical applications, which is not limited by the embodiments of the present invention.

It is within the position range of the slider, but can slide freely out of the position range of the slider. For example, the preset time length is Δt. After the slider 220 is selected by the contact point, the moving track of the contact point is shown as the moving track 230 in FIG. The position of the point at the current time t1 is the current position of the contact point, which is set as point S, and the position of the contact point at the time t0=t1-Δt is the initial position of the contact point, which is set as point Q, and the moving direction of the contact point is Point Q points to point S, the direction component of the moving direction of the contact point on the slide rail is point Q pointing to point R, and the first included angle between the moving direction of the contact point and the slide rail is ∠SQR.
