Detailed ways

1 is a schematic flowchart of an icon display method for a smart terminal according to a preferred embodiment of the present invention. The icon display method includes the following steps:

S101: Create a three-dimensional coordinate system in the smart terminal, where the three-dimensional coordinate system includes an x-axis, a y-axis, and a z-axis.

In this step, a three-dimensional coordinate system is created in the smart terminal, that is, a rectangular coordinate system including an x-axis, a y-axis, and a z-axis. The coordinate unit of the three-dimensional coordinate system is an integer, and can be represented by a pixel, so that the icon to be displayed is represented by a position, and the display content is conveniently processed.

S102: Set, for each icon in the desktop launcher of the smart terminal, a three-dimensional position coordinate in the three-dimensional coordinate system, wherein three-dimensional position coordinates of all icons are evenly distributed on the same spherical surface, the spherical center of the sphere Located at an origin of the three-dimensional coordinate system, the radius of the spherical surface is not more than one-half of the width of the display interface of the smart terminal, and the plane of each icon is tangent to the spherical surface.

The desktop launcher, that is, the Launcher, is a common component in the Android operating system, and is used to manage the desktop display of the smart terminal, and the developer puts the icons, files, and the like that need to be displayed into the desktop launcher. The implementation displays the icons and files on the desktop. The object of this step operation is each icon in the desktop launcher, that is, an icon displayed on the desktop of the smart terminal. In this step, three-dimensional position coordinates in the three-dimensional coordinate system are set for each of the icons, and the three-dimensional position coordinates are represented by a Cartesian coordinate system, that is, each icon corresponds to a three-dimensional position coordinate, and the three-dimensional position coordinates correspond to the The center point of the icon. For example, for an icon, its three-dimensional position coordinates are (0, 100, 0), and the center point of the icon is on the positive half-axis of the y-axis. In this step, the three-dimensional position coordinates of the icon are further restricted, and the three-dimensional position coordinates of all the icons are evenly distributed on the same spherical surface, that is, the distance between the three-dimensional position coordinates of each icon and the spherical center of the spherical surface is equal. And the three-dimensional position coordinates of the adjacent two icons are equal in arc length on the spherical surface. The center of the sphere coincides with the origin of the three-dimensional coordinate system, and thus the icons may be distributed within respective quadrants of the three-dimensional coordinate system. The radius of the spherical surface is not more than one-half of the width of the display interface, so as to meet the content of the entire spherical surface of the display interface of the smart terminal in a subsequent step. For example, if the width of the display interface is 400 pixels, the radius of the spherical surface is at most 200 pixels. Each icon is itself a two-dimensional picture, the icon is located in a two-dimensional plane, and when the icon is distributed on the spherical surface, the plane in which the icon sits also has its own direction, that is, the plane Tangent to the spherical surface. In another expression, the plane of the icon is perpendicular to the spherical radius of the three-dimensional position coordinates passing through the icon.

S103: a plane composed of the y-axis and the z-axis is used as a projection plane, and each of the icon projections is displayed on the projection plane to obtain a corresponding icon projection, wherein an icon located in the negative semi-axis area of the x-axis The icon projection is displayed as a ghost image.

This step defines a plane composed of the y-axis and the z-axis as a projection plane, the projection plane being perpendicular to the x-axis, separating the spatial region of the three-dimensional coordinate system into a region located on the positive half-axis of the x-axis and negative at the x-axis The area of the semi-axis. In this step, each of the icon projections is displayed on the projection plane, and an image corresponding to the icons is obtained, that is, an icon projection. The plane in which each icon is located is tangent to the spherical surface, so the icons at different positions have different inclination angles with respect to the projection plane, and according to the projection principle, there are icon projections of different areas. For example, the icon on the spherical "equator" near the x-axis position, that is, the z coordinate in the three-dimensional position coordinate and the icon whose x coordinate is close to 0, is approximately parallel or parallel to the projection plane, and its icon projection and The image area of the original icon is substantially equal; conversely, the icon near the lower pole of the spherical surface, that is, the icon near the z-axis, has a larger inclination angle with respect to the projection plane, so the projected area of the icon on the projection plane is relatively larger. small. This step also displays the icon projection of the icon located in the negative half-axis area of the x-axis as a ghost image, since the x-axis negative can only be seen from the positive half-axis area of the x-axis toward the projection plane. The back side of the icon of the half-axis area is visually distinguished from the icon located in the positive half-axis area of the x-axis, so that the icon of the icon of the negative-axis half-axis area of the x-axis is projected as a ghost image. The manner in which the icon projection is displayed as a ghost image is a process of homogenizing pixels projected by the icon, that is, a certain projection of the icon The pixels of all the pixels in the area are averaged in the area, and then the area is displayed according to the average value.

S104: The desktop launcher displays the projection plane.

This step displays the projection plane through the desktop launcher, including the icon projection on the projection plane. The desktop launcher opens an interface to the developer, and writes the content to be displayed through the interface, and can also define the display mode through the interface. Displaying the projection plane in such a manner that the entire projection plane is displayed as an image in a range of the display interface, and the coordinate origin of the projection plane coincides with a center point of the display interface, so that Show all icon projections. When the projection plane is displayed, the side of the projection plane that faces the positive half axis of the x-axis is directly seen from the display interface, so that the icon projection of the icon from the positive half-axis of the x-axis is projected to the front of the icon projection. Image; the icon of the icon from the negative half of the x-axis is projected as a ghost image on the reverse side. After the step is executed, an icon according to the spherical surface may be displayed on the display interface, that is, a three-dimensional graphic effect is displayed on the two-dimensional display interface, and more icons may be displayed in the same display interface than the prior art. To give users a three-dimensional and beautiful visual effect.

Referring to FIG. 2, it is a schematic flowchart of an icon display method for a smart terminal according to another preferred embodiment of the present invention. After the step S104', the icon display method further includes:

S105: The smart terminal receives a sliding touch operation.

In this step, the touch screen of the smart terminal receives a sliding touch operation performed by the user. The sliding touch operation is an operation in which the user slides a distance after contacting the touch screen and then disengages from the contact. The sliding touch operation leaves a movement trajectory on the touch screen, the movement trajectory having a starting position and an ending position, and having a moving direction. In the present invention, the sliding touch operation may be in any direction, and is not limited by the operation of turning the page left or right or turning up and down in the prior art.

S106: Rotate the spherical surface according to a moving trajectory and a moving direction of the sliding touch operation, wherein all the icons on the spherical surface rotate synchronously following the spherical surface.

In this step, a rotating operation is performed on the spherical surface, and a rotational direction and a rotational distance of the rotational operation are determined by a moving trajectory and a moving direction of the sliding touch operation. Calculating the rotation direction and the rotation distance by first determining a start position and an end position of the movement trajectory on the display interface, since the center of the display interface coincides with the origin of the projection plane, Regarding the position of the starting position and the ending position on the projection plane, it should be noted that the starting position and the ending position should be within the projection display range of the spherical surface. Then, the starting position and the ending position on the projection plane are mapped to the x-axis positive half-axis area of the spherical surface in a direction perpendicular to the projection plane, and a starting position and an ending position on the spherical surface are obtained. Then, the starting position is moved to the coordinates of the ending position according to the shortest arc length, and all the coordinate points on the spherical surface are rotated together, that is, the rotating operation of the spherical surface is realized. Since all the coordinate points of the spherical surface rotate synchronously, all the icons on the spherical surface are also rotated together, and the plane in which the icon is located maintains a state of being tangent to the spherical surface while rotating.

S107: Clear all icon projections on the projection plane.

This step clears all icon projections on the projection plane, that is, deletes all display content on the projection plane, so that new image information is projected and displayed in subsequent steps.

S108: Projecting and displaying each of the rotated icons on the projection plane to obtain a corresponding icon projection. The icon projection of the icon located in the negative half-axis area of the x-axis is displayed as a ghost image.

In this step, the rotated icon obtained in step S106 is projected and displayed, and the implementation of the projection is the same as the step S103, and details are not described herein. Since the icon follows the spherical surface and the position and inclination of the icon change, the icon projection content obtained in this step is different from the step S103.

S109: The desktop launcher displays the projection plane.

The step of controlling the desktop launcher to display the projection plane again, displaying the rotated icon projection, and providing feedback to the sliding touch operation. The effect achieved by the embodiment is that the user performs a sliding touch operation on the touch screen in any direction, and the icon of the spherical display also rotates synchronously following the sliding touch operation, just like the visual effect of dialing the globe.

In some implementations of the first aspect of the present application, in the process that the smart terminal receives a sliding touch operation in step S105, the smart terminal repeatedly performs step S106 according to a period preset in the smart terminal. Step S107, step S108, and step S109 until the sliding touch operation ends. In this embodiment, the step S106, the step S107, the step S108, and the step S109 are not sequentially executed after the sliding touch operation is completed, but are repeatedly executed according to the cycle, and the period is preferably within 0.2 seconds. . During each period, the smart terminal may detect a small partial movement trajectory of the sliding touch operation in the current period, and perform synchronous rotation and clear the icon displayed last time in the step of repeatedly performing the local movement trajectory. Projection, formation of new icon projections, display of icon projection operations. The technical effect is that the icon of the spherical display rotates synchronously with the user's sliding touch operation, and the rotation is smoother, so that the user feels that it is dialing a real sphere without hysteresis.

Referring to FIG. 3, it is a schematic diagram of a specific process in step S106 of FIG. 2 in accordance with a preferred embodiment of the present invention. The step S106 includes:

S106-1: Acquire a moving track and a moving direction of the sliding touch operation on the projection plane.

The touch position is also recorded when the sliding touch operation is recognized by the touch screen, and the set of all touch positions during the entire sliding touch operation is the moving track, and the direction of the moving track is the moving direction. Since the center of the display interface coincides with the origin of the projection plane, the coordinates of the movement track on the display interface can be converted into coordinates on the projection plane, and the moving direction can be represented by a coordinate vector. The coordinate vector is a coordinate of an end position of the movement trajectory minus a coordinate of a start position. For example, the coordinate system of the display interface is a plane rectangular coordinate system, the origin is at the lower left corner, the length of the display interface is 600 pixels, and the vertical coordinate is 400 pixels. As the abscissa, the projection plane is used. The coordinates of the origin position on the display interface are (200, 300). When converting, the moving track is subtracted by 200 from the abscissa on the display interface, and the ordinate is subtracted by 300 to obtain the coordinates on the projection plane.

S106-2: mapping the movement trajectory from the projection plane to the spherical surface in the x-axis direction to obtain a spherical trajectory.

This step performs a mapping operation, that is, mapping the movement trajectory on the projection plane to the direction perpendicular to the projection plane, that is, the direction of the x-axis, to the spherical surface in the three-dimensional coordinate system, A spherical track. The spherical trajectory is located on the spherical surface of the positive semi-axis region of the x-axis, and also has a starting position and an ending position. Since the y coordinate and the z coordinate of the movement trajectory on the projection plane have been obtained in step S106-1, when it is mapped to the spherical surface along the x-axis The x coordinate is also determined, so the three-dimensional coordinates of the spherical trajectory are known.

S106-3: Obtain three-dimensional coordinates of the starting position of the spherical trajectory and three-dimensional coordinates of the ending position, and calculate polar coordinates of the starting position and the ending position.

This step introduces the concept of polar coordinates. For the spherical surface, the spherical coordinate system can also be used to represent the coordinate position. It takes the coordinate origin as the reference point and is composed of azimuth, elevation and distance. That is, the radial distance r between the origin and the point P on the spherical surface, the elevation angle a between the line from the origin to the point P and the positive half of the z-axis, and the line connecting the origin to the point P on the x-axis and the y-axis The azimuth angle b between the projected line and the positive x-axis, ie (r, a, b) constitutes the polar coordinate parameter. There is a conversion relationship between polar coordinates and rectangular coordinates, as follows:

1) x = r × sina × cosb;

2) y = r × sina × sinb;

3) z = r × cosa;

The three-dimensional rectangular coordinates of the start position and the end position of the spherical trajectory can be converted into polar coordinates by the above relationship.

S106-4: Calculate the angular difference of the polar coordinates of the start position and the polar coordinates of the end position.

Since the starting position and the ending position of the spherical trajectory are different, there are different polar coordinate parameters, and the elevation angle and the azimuth angle of the ending position are respectively subtracted from the elevation angle and the azimuth angle of the starting position, that is, the angle is obtained. difference. For example, the polar coordinates of the starting position are (200, 50, 30), the polar coordinates of the ending position are (200, 70, 40), and the elevation angle is increased by 20 degrees, which is the elevation angle difference, and the azimuth angle is increased by 10 Degree, which is the difference in azimuth, is called the angle difference. The angle difference may also be a negative number depending on the position and direction of the spherical trajectory.

S106-5: Calculate the three-dimensional position coordinates of the three-dimensional position coordinates of all the icons on the spherical surface according to the angle difference.

This step calculates the new three-dimensional position coordinates of all the icons on the spherical surface, that is, the new three-dimensional position coordinates of the center positions of all the icons. The calculation method is to first convert the original three-dimensional position coordinates of the icon into polar coordinates, and then add the elevation angle and the azimuth angle in the polar coordinates to the difference between the elevation angle and the azimuth angle in the angle difference, respectively, to obtain a new polar coordinate. Then convert the new polar coordinates to the new 3D position coordinates.

S106-6: For each icon, adjust the position according to the new position coordinates of the icon, and keep the plane where the icon is located tangent to the spherical surface.

In this step, all the icons are arranged on the spherical surface according to the new position coordinates, and the plane in which the icon is located is kept tangent to the spherical surface. Since the coordinate position of the icon changes, the original plane where the icon is located is no longer tangent to the new spherical position and needs to be adjusted. The adjustment is such that the plane in which the icon is located is perpendicular to the radius passing through the three-dimensional coordinate position of the icon.

Referring to FIG. 4, it is a schematic diagram of a specific process in step S103 in FIG. 1 in accordance with a preferred embodiment of the present invention. The step S103 includes:

S103-1: Calculate the distance of each icon from the horizontal plane composed of the x-axis and the y-axis.

The x-axis and the y-axis form a horizontal plane, and the distance between the icon and the horizontal plane is the absolute value of the z-coordinate of the icon. The distance reflects the distance of the icon from the "equatorial plane" of the spherical surface, and is reflected on the projection plane as the distance the icon is projected from the horizontal centerline of the projection plane.

S103-2: Multiplying each of the distances by a scaling factor preset in the smart terminal to obtain a compression ratio coefficient corresponding to the icon.

A proportional coefficient is preset in the smart terminal, and the step multiplies the distance by the proportional coefficient to obtain a compression ratio coefficient for each of the icons. For example, if the distance of an icon is 150 and the scale factor is 0.005, the compression ratio coefficient is 0.75. In the embodiment, the compression ratio coefficient is proportional to the distance and is less than or equal to 1.

S103-3: compress the corresponding icon according to the compression ratio coefficient.

This step performs a compression operation, that is, compresses the icon according to the pixel size, and refers to the compression ratio coefficient obtained in step S103-2 during compression. For example, for an icon, the corresponding compression ratio coefficient is 0.75, and the icon is compressed by 75% to become the original 25% size, the original pixel area of the icon is 60*60, and the compression becomes 15*15.

S103-4: Projecting the compressed icon on the projection plane to obtain a corresponding icon projection.

In this step, a projection operation is performed, and the compressed icon is projected on the projection plane to obtain a corresponding icon projection. The area of the icon projection is calculated by multiplying the area of the icon by the cosine of the icon inclination.

S103-5: Convert the icon projection of the icon located in the negative half-axis area of the x-axis to a ghost image.

This step performs a ghosting conversion operation, and the execution object is an icon projection of an icon located in the negative half-axis area of the x-axis. The specific implementation has been explained in the description of step S103 in the foregoing.

5 is a schematic structural diagram of an icon display device for a smart terminal according to a preferred embodiment of the present invention. The icon display device 10 includes:
