Detailed Description

In order to more clearly illustrate the present invention, the present invention is further described below with reference to the following examples and the accompanying drawings. Similar components in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

A first embodiment of the present invention provides a method for generating a book-type navigation bar, which is applied to a display terminal, such as a computer shown in fig. 1, and may also be applied to display products installed with various applications, such as a smart phone, a computer, a smart television, and a notebook computer.

As shown in fig. 2, in an optional embodiment, the method for generating the book-type navigation bar includes:

s1, generating a book cover of the book type navigation bar according to a page image of a display terminal;

s3, acquiring an application image according to the application installed on the display terminal;

s5, generating a corresponding application inner page of the book type navigation bar according to the application image;

and S7, overlapping the application inner pages with the same attribute, and splicing the application inner pages with the book covers to form the book type navigation bar of the application corresponding to the attribute.

According to the technical scheme, the book cover is generated according to the page image of the display terminal, the application inner page corresponding to the application is generated according to the application installed on the display terminal, the applications with the same attribute are overlapped in the page mode, so that the inner page of the book type navigation bar is formed, the book type navigation bar is formed after the inner page and the cover are overlapped, and the problem that the bottom of a screen is shielded by the navigation bar and the occupied area is large can be solved.

As shown in fig. 3, the book-type navigation bar of the present embodiment is in an open state when not in use, and when a user responds to a key operation of the user through a controller, for example, a remote controller, and the remote controller outputs a page turning instruction, the book-type navigation bar changes from the open state to the closed state in response to the page turning instruction, as shown in fig. 4, and an application is displayed in a page for the user to select.

The book type navigation bar of the embodiment can centralize a plurality of applications in the same navigation, so that the problem of icon occupation of different applications is solved, the book type navigation bar of the embodiment occupies a small area, the shielding of the bottom of a screen is small, and the management, browsing and displaying of all the applications are realized by using a small layout.

The above-described method of an embodiment of the present invention will now be described with specific examples.

S1, generating book covers of the book type navigation bar according to page images of a display terminal.

In this step, the page image as the book cover may be a homepage wallpaper of the display terminal, may be a system picture, and may also be a user-defined picture, which is not limited herein.

The book cover comprises a front cover located on the front page, a back cover located on the back page and a spine connecting the front cover and the back cover. That is, the displayed image of the book cover of the present embodiment is continuous and complete, thereby improving the user experience.

In an alternative embodiment, as shown in fig. 5, the generating the book cover of the book-type navigation bar according to the page image of the display terminal further comprises:

s11, determining the size of the book cover according to the display size of the display terminal, wherein the size of the book cover comprises a first length in a first direction and a second length in a second direction, and the second direction is perpendicular to the first direction.

In a specific example, if the page image is a home wallpaper of the current display terminal, the image size and the display size of the home wallpaper are consistent, so that the size of the book cover can be determined according to the size of the display terminal. As shown in fig. 6, the home wallpaper has a large original size, and the book cover can be obtained only after the home wallpaper is zoomed.

As shown in fig. 6 and 7, the first direction of the present embodiment is the X direction of the drawing, and the second direction is the Y direction of the drawing. In an alternative embodiment, the second length is determined based on a length scaling of said home wallpaper in the direction, the length of the scaled home wallpaper in the first direction being said first length.

That is, the present embodiment adjusts the page image according to the display screen height of the display terminal so that the page image satisfies the size of the spine cover.

Illustratively, the zoom size is k, if the display terminal is 110 inches, k =1/6, that is, the page image is reduced to 1/6 of the original size with the Y direction as a reference; if the display terminal is a 98-inch screen, k =1/5, that is, reducing the page image to 1/5 of the original size by taking the Y direction as a reference; if the display terminal is an 85-inch screen, k =1/4.5, that is, the page image is reduced to 1/4.5 of the original size by taking the Y direction as a reference; if the display terminal is 75 inches, k =1/4, that is, the page image is reduced to 1/4 of the original size by taking the Y direction as a reference. The above is only an example, and the screen size and the zoom parameter of the display terminal may be designed according to the actual application, and are not described herein again.

Based on the above embodiment, the relationship between the second length H of the book cover and the display size is: h = height of page image k, k is the scaling parameter.

Further, since the scaling is performed by overall scaling, as shown in fig. 7, the scaled page image has a size in the Y direction that is not only changed, but also changed, and the size of the scaled page image in the X direction is the first length W of the book cover.

In the step, the page image of the display terminal is zoomed, so that the book cover of the book type navigation bar is obtained.

S13, determining the number of applications with the same attribute, and determining the first thickness of the book spine in a third direction according to the number of applications with the same attribute, wherein the third direction is perpendicular to the first direction and the second direction.

In this embodiment, one application is used as the inner page of the book, and therefore, when the number of applications is larger, the number of inner pages of the book is larger, and the thickness of the whole book-type navigation bar is also thicker, and therefore, this step determines the thickness of the book-type navigation bar through the number of applications, and further determines the thickness of the spine.

In this embodiment, applications with the same attribute are set in one book-type navigation bar, that is, the book-type navigation bar of this embodiment may have multiple applications, and each book-type navigation bar can meet different requirements, for example, each app for video playing may be set in one book-type navigation bar, each app for music playing may be set in one book-type navigation bar, each app for text editing may also be set in the same book-type navigation bar, and a related command or program is set in one book-type navigation bar.

In another specific example, attribute similarity is determined by determining functions of various applications, and different types of applications are arranged in the same book-type navigation bar according to the similarity, so that the navigation occupied area is further saved. For example, each app for music playing, app for video playing, voice calling and the like has a function of executing and calling a microphone, a speaker and the like in terms of functions, the apps can be set in the same book navigation, and based on the similarity, the arrangement sequence of the application inner pages in the book-type navigation bar can be set, so that the navigation is quickly queried, and the occupied area is saved. In a specific example, the thickness of the application internal page corresponding to each application is set to be D, and illustratively, the thickness D of the application internal page is related to a pixel p of the display terminal, for example, D = mp, (m is a constant).

If the user has n applications installed, then in a third direction, i.e. the Z direction, i.e. the thickness direction, the first thickness of the spine dtotai = D1+ D2+ … + Dn = n × mp

Suppose that: n =10; m =2, and m is a linear chain,

the first thickness dtotal of the spine: d1+ D2+ … + D10=10 × 2p

In this embodiment, the first thickness of the spine is determined based on the number of applications and the thickness of the pages within the applications.

S15, cutting the page image according to the first thickness, the first length and the second length of the book spine to form the front cover, the back cover and the book spine.

As shown in fig. 7, in the fully unfolded state of the book cover, in the first direction X, the first length W of the book cover is the sum of the width of the front cover, the first thickness of the spine, and the width of the back cover in the direction, and in order to ensure that the book cover completely wraps and symmetrizes the inner pages, the width of the front cover and the width of the back cover are the same, so in this embodiment, the width of the front cover W1 and the width of the back cover W2 are both (W-D)/2. It can be seen that, for a complete book cover, each part of the book cover can be cut out based on the second length H, the front cover width W1, the back cover width W2, and the first thickness D of the spine.

S17, splicing the front cover, the spine and the back cover in sequence, wherein the image content displayed by the book cover is complete image content displayed by the page image.

For example, as shown in fig. 7, the image content corresponding to the front cover is located on the left side, the image content corresponding to the spine is located in the middle, the image content corresponding to the back cover is located on the right side, and in a completely opened state, the image content displayed by the book cover is the image content displayed by the complete page image, so that the book cover with complete content is obtained.

As shown in fig. 3, when the number of applications is large, the number of application inner pages is large, and the edges of the application inner pages close to the back cover and the application inner pages close to the front cover are offset, so that the inclination state of the spine and each application inner page is designed to accurately simulate the book shape of the book-type navigation bar.

In an alternative embodiment, as shown in fig. 8, before the step S17 "splicing the front cover, the spine and the back cover in sequence", the method further comprises:

s161, determining the inclination angle formed by the book spine and the back cover according to the first thickness and the number of the application images.

Based on the number of application images and the single thickness of the application inner page determined in the previous step, in this step, as shown in fig. 3, the inclination angle formed by the spine and the back cover can be determined according to a preset page simulation algorithm. Illustratively, the larger the number of application inner pages, the larger the tilt angle of the simulated book navigation, in one specific example, the tilt angle θ is a linear function of the number of application inner pages n, i.e., θ = n θ _k Wherein θ _k Is a preset tilt angle of the inner page of an application.

In another specific example, the inclination angle θ is a piecewise function of the number n of application inner pages, and considering that the inclination angle of a single page corresponding to an application inner page is small, the embodiment performs piecewise setting on the inclination angle, for example, when the application inner page is 1-10 pages, the inclination angle is 1 °, and when the application page is 11-30 pages, the inclination angle is 5 °.

And S163, carrying out inclination conversion on the cut page image corresponding to the book spine according to the inclination angle to form the book spine.

Further, in this step, as shown in fig. 7, the spine is rectangular in the flat state, and as shown in fig. 3, the spine is a quadrangle that is inclined in the closed state, and therefore, the rectangular spine is inclined to form a three-dimensional book side with the boundary where the back cover and the spine intersect as an inclined boundary according to the inclination angle θ determined in the above step.

S165, determining the offset distance of the front cover relative to the back cover according to the inclination angle so as to determine the position of the front cover in the state that the book type navigation bar is not turned.

For example, there is an offset distance between the application inner page and the back cover of each application, for example, the offset distance is 2 unit pixels, or the offset distance is multiple unit pixels.

In this embodiment, the first thickness of the book navigation, that is, nD, can be determined according to the number of applications n and the thickness D of the application page, and the tilt angle is θ, and as can be seen from the pythagorean theorem, the offset distance I between the top cover and the bottom cover satisfies the tangent formula, that is, nD/I = tan θ.

After the offset distance of each application is obtained based on the inclined boundary where the back cover and the spine overlap, for example, the side edge of each application inner page is offset by two pixels, the offset distance of each application inner page and the offset distance of the top cover can be determined after the offset, thereby realizing the book-type simulation of the simulated navigation.

for example, for a non-native installed application, the installed application does not enter the application, and for this type of application, the page image may only display the icon and the application name.

In another example, application screenshots are taken at the first launch of each application, with the application screenshots as page images. Through the arrangement, each application has the screenshot page corresponding to the application, and based on the steps, the offset distance is reserved between the inner pages of the adjacent applications, so that different applications have different visual effects, and the navigation effect of the book type navigation bar is improved.

In another specific example, the application image of each application may be set by itself according to a setting instruction of the user, so that the application image of the installed application is acquired in advance.

And S5, generating the corresponding application inner page of the book type navigation bar according to the application image.

As shown in fig. 9 and 10, the book-type navigation bar of the present embodiment includes a plurality of application inner pages of applications, where the application inner pages include a first page and a second page, and in an unfolded state, the first page is close to the front cover, and the second page is close to the back cover, that is, the application pages of the present embodiment include two front and back pages, and the next application is displayed after page turning is implemented in a book page manner. The front page and the back page of the embodiment correspond to the same application, but the two adjacent pages in the tiled state correspond to the same application, and through the setting, two different applications are displayed simultaneously in the page turning state.

In an alternative embodiment, as shown in fig. 11, the step S5 "generating the application inner page of the book-type navigation bar according to the application image" further includes:

s51, determining a third length of the application inner page in the first direction and a fourth length of the application inner page in the second direction according to the size of the cover.

Based on the process in the foregoing step S1, the book cover wraps the application inner page, and in this embodiment, the size of the application inner page can be determined according to the size of the book cover, for example, as shown in fig. 10, the third length of the application inner page can be set to be consistent with the width of the front cover in the direction, or consistent with the width of the back cover in the direction, and the fourth length of the application inner page can be set to be consistent with the length of the front cover in the second direction, or consistent with the length of the back cover in the direction.

And S53, determining the second thickness of each application inner page in the third direction according to the display size of the display terminal.

Illustratively, based on the example in the foregoing step S1, the thickness of the application internal page corresponding to each application is set to be D, and illustratively, the thickness D of the application internal page is related to the pixel p of the display terminal, for example, D = mp, (m is a constant). I.e. the second thickness is D.

And S55, converting the application image into an application inner page meeting the third length, the fourth length and the second thickness.

For example, based on the process of "acquiring an application image according to the application installed on the display terminal" in step S3, the main interface of the application may be captured in a screen capture manner, and there may be a case where the size of the application image generated by the screen capture is inconsistent.

In an alternative embodiment, as shown in fig. 12, the step S55 "converting the application image into the application inner page satisfying the third length, the fourth length, and the second thickness" further includes:

s551, reducing the fourth length of the application image to the second length, and obtaining the third length of the application image according to the thickness of the book spine and the first length;

in the step, the length of the application image is kept consistent with the length of the page image through scaling, so that the book type navigation bar is accurately simulated.

In this embodiment, it is kept the same length of the application image and the page image in the second direction, and since the page image forming the book cover also includes a part of the spine, the length of the application image in the first direction is not the same as the length of the book cover in the first direction, but is the same as the width of the back cover or front cover in that direction, thereby obtaining an application inner sheet that is the same size as the front cover or as the back cover.

And S553, splitting the application image to obtain a first application image and a second application image by splitting the boundary of the application image parallel to the central line of the side edge of the book spine.

In this embodiment, as shown in fig. 9, one application corresponds to two application inner pages, and therefore, in this embodiment, the content of one application image is split, so that the application content can be displayed on both the first inner page and the second inner page. Further, in order to ensure the display effect, the boundary is split by a central line parallel to the side edge of the book spine, and the central line of the application image in the first direction is taken as an axis to form a first application image and a second application image which are symmetrical.

And S555, respectively setting the image contents of the first application image and the second application image on two side pages of the same page.

As shown in fig. 9, the first application image is set on the front side of the same page, and the second application image is set on the back side of the same page, so as to realize page simulation of the book-type navigation bar.

Based on the steps, after the application pages of each application are formed, a subsequent process of overlapping the application pages is performed.

In an alternative embodiment, as shown in fig. 13, the step S7 "superimposing the application inner page with the same attribute as the book inner page, and splicing with the book cover to form the book-type navigation bar of the application corresponding to the attribute" further includes:

and S71, taking the back cover as the back cover of the book type navigation bar. To perform the overlay of the application inner page on the back cover.

And S73, taking the splitting boundary of each application image as a folding side edge close to one side of the book spine.

Based on the step S553, the application image is split into the first page image and the second page image, and in the step, the split boundary of the first page image and the second page image is used as the folded side edge near the spine, and the application pages are stacked.

And S75, overlaying all application inner pages under the attribute on the cover bottom.

In the stacking process, all the application inner pages with the same attribute take the split boundaries as the turnover sides to be gathered to one side of the book spine, and after stacking, the application inner pages with the thickness are formed.

And S77, overlapping the front cover on the application inner page far away from the back cover, wherein the back cover is close to the boundary of the turnover side edge, the front cover is close to the boundary of the turnover side edge, and the turnover side edge forms the book spine.

After the application inner pages with the same attribute are overlapped, a cover is overlapped on the application inner page positioned at the top, so that the cover and the cover wrap the overlapped application inner pages, and after the cover and the cover are overlapped, the page image corresponding to the spine covers the turned-over side edges of all the application inner pages to form the spine.

In a specific example, the present embodiment does not limit the stacking order of the plurality of application inner pages, that is, the application inner pages close to the back cover side are stacked in the stacking order of the application 1 and the application inner pages far from the back cover side are stacked in the stacking order of the application n.
