Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of icons gathering in a circle and scrolling in a circle as a sliding of a pointer according to an embodiment of the present invention. As shown in fig. 1, in the present embodiment, the user operation is divided into three types: press (the pointer such as the user's finger just touches the screen), slide (the pointer such as the user's finger slides on the screen), lift (the pointer such as the user's finger leaves the screen). The three types correspond to different processing logic in fig. 1.
In this embodiment, when a pointer such as a finger or the like presses the screen but does not slide, the icons on the screen remain at the initial positions, for example, in the conventional landscape arrangement. When a pointer such as a finger slides on the screen, the icons on the screen gradually gather into a circle as the pointer slides on the screen. Specifically, when the sliding distance is less than the threshold distance of sliding required for gathering the icons into a circle, the rotation angle of each icon and the abscissa and ordinate which are coordinate positions are calculated, and the icons are moved according to the calculated result; until the icons gather into a circle when the sliding distance equals the threshold distance; and when the sliding distance is greater than the threshold distance, namely the icons are gathered into a circle, calculating a new coordinate position of the circle center of the circle, the rotation angle and the new coordinate position of each corresponding icon, and rolling the circle according to the calculated result. When the pointer such as a finger or the like is lifted off the screen, in the present embodiment, the icons are restored to the original positions, for example, in the conventional horizontal row arrangement.
In the present embodiment, when the sliding distance is equal to the threshold distance, the center position and the radius of the circle gathered by each icon are predefined values on the screen, and thus the gathered circle is fixed, and the rotation angle and the coordinate position of each icon on the circle are related to the number of icons. The coordinate position of each icon will be determined according to equation 1:
x1＝x0+r×cos(θ1)
y1＝y0+r×sin(θ1)
Wherein x is0Is the abscissa of the center of the circle, y0Is the ordinate of the circle center, which is also referred to herein as the first circle center abscissa and the first circle center ordinate, respectively, for the sake of brevity. x is the number of1Is the abscissa, y, of the corresponding icon when the icons are gathered into a circle1Are the ordinates of the corresponding icons when they are brought together in a circle, which are also referred to herein, for brevity, as the first icon abscissa and the first icon ordinate, respectively. Theta1Which represents a rotation angle of each icon in a circle when the circle is formed, the rotation angle having a horizontal right as a start edge and a counterclockwise as a positive angle, and is also referred to as a first icon rotation angle herein for brevity. r is the radius of the circle to be gathered. As described above, in the present embodiment, the circle radius, the first circle center abscissa, and the first circle center ordinate are predefined values on the screen.
The first icon rotation angle for each icon will be determined according to equation 1. Assuming that there are N icons on the current screen, in the present embodiment, in order to make the icons equally spaced in the circle to be gathered, the first icon rotation angle of each icon is as shown in formula 2:
I.e. the circle is divided into N equal parts, the angle of each part, i.e. the rotation angle theta of the first icon1Take the above N values.
In the above, according to the formula 1 and the formula 2, the coordinate position and the rotation angle in the circle when the icons are gathered together into the circle can be calculated.
Specifically, if the user operation is that the user presses the screen through the pointer without sliding in S110, the icons are held in the initial positions, for example, in the conventional landscape arrangement in S111.
In S120, the user slides on the screen through the pointer.
In S121, whether the icons are rounded is determined according to whether the sliding distance is smaller than a threshold distance of sliding required for the icons to be rounded. When the sliding distance is less than the threshold distance, the icons start to move but have not been gathered into a circle in S122. Calculating the coordinate position of the icon in the process of gathering the icon into a circle according to formula 3:
x2＝(x1-xs)×currD/d+xs
y2＝(y1-ys)×currD/d+ys
equation 3
Wherein x is1The abscissa of the icon when the icon is gathered into a circle is the first icon abscissa, y1The ordinate of the icons when the icons are gathered into a circle is the ordinate of the first icon; x is the number ofsIs the abscissa, y, of the icon at its initial positionsIs the ordinate of the icon at the initial position; currD is the sliding distance of the current indicator, d is the threshold distance of sliding required for the icons to gather into a circle, and in the S122 scenario, currD<d；x2Is the abscissa, y, of the icon during its gathering into a circle2The ordinate of the icon during its gathering into a circle is also referred to herein, for brevity, as the second icon abscissa and the second icon ordinate, respectively.
Calculating the rotation angle of the icon in the process of gathering the icon into a circle according to formula 4:
θ2＝currD/d×θ1
equation 4
Wherein curD is the current indicator, as described aboveSliding distance, d is the threshold distance of sliding required for the icons to gather into a circle, in the scenario of S122, currD<d；θ1The rotation angle of the icons in the circle when the icons are gathered into the circle is the first icon rotation angle; theta2The rotation angle of the icons during the process of gathering the icons into a circle is referred to herein as the second icon rotation angle for brevity.
As can be seen, in S122, the rotation angle and the coordinate position of each icon are calculated based on the sliding ratio, and the icon is moved according to the calculation result. In the present embodiment, the icons are moved along a straight line and are rounded, but the present invention is not limited to this, and the icon modules may be moved along an arc, a bezier curve, or the like and rounded.
In S124, i.e., the branch of "yes" in both S121 and S123, when the sliding distance is equal to the threshold distance, the icons are gathered into a circle. That is, in the scenario of S124, currD ═ d, at this time, x is according to equation 3 and equation 42＝x1，y2＝y1，θ2＝θ1. And respectively calculating the rotation angle of the icon in the circle when the icon is gathered into the circle, and the abscissa and the ordinate according to the formula 2 and the formula 1. In this implementation, optionally, the rotation angle of each icon when the user presses the screen, i.e., in S111, and the abscissa and the ordinate when the icons are to be rounded up may be calculated.
Fig. 2 is a graph of circles gathered by icons according to an embodiment of the present invention. As shown in fig. 2, point F represents the icon in its initial position, and point F' represents the position of the icon when it is gathered into a circle. It can be seen that the icons are distributed around a fixed radius on the circumference of the circle with the fixed point as the center of the circle. For the sake of simplicity, each icon is assumed to be a point, but the specific technical concept does not differ by changing the icon into a point and does not cause the result to be incorrect.
In S125, that is, in S121, the branch is "no" in S123, when the sliding distance is greater than the threshold distance, a new coordinate position of the center of the circle and the rotation angle and the coordinate position of the icon are calculated so that the circle is scrolled according to the calculation result. Calculating the coordinate position of the circle center in the circular rolling process according to formula 5:
x′0＝x0+currD-d
y′0＝y0
equation 5
Wherein x is0Is the abscissa of the first circle center, y0Is a first circle center longitudinal coordinate; x'0Is the abscissa of the circle center in the circle center rolling process, y'0The ordinate of the circle center during the circle center rolling process is also referred to as a second circle center abscissa and a second circle center ordinate, respectively, herein for brevity; currD is the sliding distance of the current indicator, d is the threshold distance of sliding required for the icons to gather into a circle, and in the S125 scene, currD>d. From equation 5, it can be seen that the center of the circle translates in a straight line.
The rotation angle of the icon in the scrolled circle is calculated according to equation 6:
equation 6
Wherein, theta1Is a first icon rotation angle; theta3Is the angle of rotation of the icon in the circle during the scrolling of the circle, which is also referred to herein for brevity as the third icon angle of rotation; currD is the sliding distance of the current indicator, d is the threshold distance of sliding required for the icons to gather into a circle, and in the S125 scene, currD>d；
The roll angle per unit sliding distance for a circle, for example, is the corresponding roll angle for a circle for each 1 pixel translation of the pointer, and accordingly, the units of currD and d are also pixels at this time.
The abscissa and ordinate of the icon during the scrolling of the circle may be calculated according to equation 1, but should be taken to be (x'0，y′0) As a center coordinate, and theta should be adopted3As the angle of rotation of the icon in the circle. That is, equation 1 is rewritten as equation 7 below:
x3＝x′0+r×cos(θ3)
y3＝y′0+r×sin(θ3)
equation 7
Wherein, x'0Is a second circle center abscissa, y'0Is the second center ordinate, θ3Is a third icon rotation angle, x3Abscissa, y, of the icon during scrolling in a circle3The ordinate of the icon during circular scrolling is also referred to herein, for brevity, as the third icon abscissa and the third icon ordinate, respectively.
FIG. 3 is a graph of the scrolling of circles gathered by icons according to an embodiment of the present invention. Where the solid circles represent circles initially gathered by the icons that have not been scrolled, and the dashed lines represent circles that scroll as the pointer is slid horizontally to the left. As shown in fig. 3, point B represents the position of the icon when gathered into a circle, and point E represents the position of the icon when the circle is scrolled. For the sake of simplicity, each icon is assumed to be a point, but the specific technical concept does not differ by changing the icon into a point and does not cause the result to be incorrect. As shown in fig. 3, as the sliding distance of the pointer increases, the point a representing the center of the circle gradually translates to the point C in the negative direction of the x-axis, and the point B representing the icon moves to the point E — but not in a straight line at this time. When the sliding distance of the indicator is currD (currD), as described in step S125 of fig. 1>d) When the coordinates of the point A are (x)0，y0) And the coordinate of point C is (x'0，y′0) The included angle between the ray AB in the clockwise direction and the positive direction of the x-axis is theta1The included angle between the clockwise direction of the ray CE and the positive direction of the x-axis is theta3。
In S126, the pointer such as a finger is lifted off the screen.
In S127, the icon is restored to the original position, for example, to the normal horizontal arrangement. In this embodiment, when the pointer is lifted off the screen, the rotation angle of the icon is set to 0 degrees, and the translation distance between the horizontal axis (x-axis) and the vertical axis (y-axis) is also set to 0, and this process is completed by animation.
Fig. 4 to 7 are schematic diagrams of icons in different positions according to different user operations according to an embodiment of the present invention.
