[0090] In order to explain the present invention more clearly, the present invention is further described below in conjunction with embodiments and drawings. Similar components in the drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and the protection scope of the present invention should not be limited thereto.

[0091] The first embodiment of the present invention provides a method for generating a book-style navigation bar, which is applied to a display terminal, such as Figure 1 The computer shown can also be applied to display products installed with multiple applications, such as smart phones, computers, smart TVs, and laptops.

[0092] like Figure 2 As shown, in an optional embodiment, the method for generating the book-style navigation bar includes:

[0093] S1, generating a book cover of the book-style navigation bar according to a page image of a display terminal;

[0094] S3, acquiring an application image according to an application installed on the display terminal;

[0095] S5, generating an application inner page of the corresponding book-style navigation bar according to the application image;

[0096] S7. Overlaying an inner page of an application with the same attribute and splicing it with the book cover to form a book-style navigation bar of the application corresponding to the attribute.

[0097] The technical solution described in the present invention generates a book cover according to the page image of the display terminal, generates application inner pages corresponding to the application according to the application installed in the display terminal, and superimposes applications with the same attributes in the form of book pages to form inner pages of a book-like navigation bar. The inner pages and the cover are superimposed to form a book-like navigation bar, which can solve the problem that the navigation bar blocks the bottom of the screen and occupies a large area.

[0098] like Figure 3As shown, the book-like navigation bar of this embodiment is in a closed state when not in use. When the user uses a controller, such as a remote controller, to respond to a key operation of the user, and the remote controller outputs a page turning instruction, the book-like navigation bar changes from the closed state to the open state for turning the page in response to the page turning instruction. Figure 4 As shown, the application is displayed on the page for the user to select.

[0099] The book-style navigation bar of this embodiment can concentrate multiple applications in the same navigation, saving the problem of icon occupation of different applications. In addition, the book-style navigation bar of this embodiment occupies a smaller area and obstructs less the bottom of the screen, and a smaller layout is used to achieve management, browsing and display of all applications.

[0100] The above method of the embodiment of the present invention is now described with specific examples.

[0101] S1. Generate a book cover of the book-style navigation bar according to a page image of a display terminal.

[0102] In this step, the page image used as the book cover may be a homepage wallpaper of the display terminal, a system image, or a user-defined image, which is not limited in this embodiment.

[0103] The book cover includes a front cover located on the first page, a back cover located on the bottom page, and a spine connecting the front cover and the back cover. In other words, the image displayed by the book cover of this embodiment is continuous and complete, thereby improving user experience.

[0104] In an optional embodiment, if Figure 5 As shown, the generating of the book cover of the book-style navigation bar according to the page image of the display terminal further comprises:

[0105] S11. Determine a size of the book cover according to a display size of the display terminal, wherein the size of the book cover includes a first length in a first direction and a second length in a second direction, wherein the second direction is perpendicular to the first direction.

[0106] In a specific example, if the page image is the homepage wallpaper of the current display terminal, the image size of the homepage wallpaper is consistent with the display size, so the size of the book cover can be determined according to the size of the display terminal. Figure 6 As shown, the original size of the homepage wallpaper is large, and the homepage wallpaper needs to be scaled to get the book cover.

[0107] like Figure 6 and Figure 7As shown, the first direction of this embodiment is the X direction shown in the figure, and the second direction is the Y direction shown in the figure. In an optional embodiment, the second length is determined by scaling the length of the homepage wallpaper in this direction, and the length of the scaled homepage wallpaper in the first direction is the first length.

[0108] That is to say, this embodiment adjusts the page image according to the display screen height of the display terminal so that the page image meets the size of the spine cover.

[0109] For example, the scaling size is k. If the display terminal is a 110-inch screen, k=1 / 6, that is, the page image is scaled down to 1 / 6 of the original size based on the Y direction; if the display terminal is a 98-inch screen, k=1 / 5, that is, the page image is scaled down to 1 / 5 of the original size based on the Y direction; if the display terminal is an 85-inch screen, k=1 / 4.5, that is, the page image is scaled down to 1 / 4.5 of the original size based on the Y direction; if the display terminal is a 75-inch screen, k=1 / 4, that is, the page image is scaled down to 1 / 4 of the original size based on the Y direction. The above are only examples, and the screen size and scaling parameters of the display terminal can be designed according to actual applications, which will not be repeated here.

[0110] Based on the above embodiment, the relationship between the second length H of the book cover and the display size is: H=height of the page image*k, where k is a scaling parameter.

[0111] Furthermore, since the scaling is overall scaling, such as Figure 7 As shown, the size of the scaled page image not only changes in the Y direction, but also changes in the Y direction. The size of the scaled page image in the X direction is the first length W of the book cover.

[0112] In this step, the page image of the display terminal is scaled to obtain a book cover of the book-style navigation bar.

[0113] S13. Determine the number of applications of the same attribute, and determine a first thickness of the spine in a third direction according to the number of applications of the same attribute, wherein the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0114] In this embodiment, an application is used as an inner page of a book. Therefore, the more applications there are, the more inner pages there are in the book, and the thicker the entire book-style navigation bar is. Therefore, this step determines the thickness of the book-style navigation bar by the number of applications, and further determines the thickness of the spine.

[0115] In this embodiment, applications with the same attributes are set in a book-style navigation bar. That is to say, there can be multiple book-style navigation bars in this embodiment, and each book-style navigation bar can meet different needs. For example, various apps for video playback can be set in a book-style navigation bar, various apps for music playback can be set in a book-style navigation bar, and various apps for text editing can also be set in the same book-style navigation bar. Related commands or programs are set in a book-style navigation bar.

[0116] In another specific example, by determining the attribute similarity of each application's functions, different types of applications are set in the same book-style navigation bar according to the similarity, thereby further saving the navigation area. Exemplarily, various apps for music playback, video playback, voice calls, etc. all have functions such as calling microphones and speakers. These apps can be set in the same book navigation, and based on the similarity, the arrangement order of the application pages in the book-style navigation bar can be set, which ensures fast navigation query and saves space. In a specific example, the thickness of the application page corresponding to each application is D by default. Exemplarily, the thickness D of the application page is related to the pixel p of the display terminal, for example, D=mp, (m is a constant).

[0117] If the user has installed n applications, then in the third direction, that is, the Z direction, that is, the thickness direction, the first thickness of the spine Dtotal = D1 + D2 + ... + Dn = n*mp

[0118] Assumptions: n = 10; m = 2,

[0119] Then the first thickness of the spine Dtotal: D1+D2+…+D10=10*2p

[0120] In this embodiment, the first thickness of the spine is determined based on the number of applications and the thickness of the inner pages of the applications.

[0121] S15. Cut the page image according to the first thickness of the spine, the first length, and the second length to form the front cover, the back cover, and the spine.

[0122] like Figure 7As shown, when the book cover is fully unfolded, in the first direction X, the first length W of the book cover is the sum of the width of the cover, the first thickness of the spine, and the width of the back cover in this direction. To ensure that the book cover completely wraps the inner pages and is symmetrical, the width of the cover and the width of the back cover are the same. Therefore, in this embodiment, the width of the cover W1 and the width of the back cover W2 are both (WD) / 2. It can be seen that for a complete book cover, based on the second length H, the width of the cover W1, the width of the back cover W2, and the first thickness D of the spine, the book cover can be cut to obtain each part.

[0123] S17, sequentially splicing the front cover, the spine and the back cover, wherein the image content displayed on the book cover is the image content displayed on the complete page image.

[0124] For example, Figure 7 As shown, the image content corresponding to the cover is located on the left, the image content corresponding to the spine is located in the middle, and the image content corresponding to the back cover is located on the right. When the book is fully opened, the image content displayed on the cover is the complete image content displayed on the page image, thereby obtaining a book cover with complete content.

[0125] like Figure 3 As shown, when the number of applications is large, the number of application pages is large, and there is an offset between the edges of the application pages close to the back cover and the application pages close to the front cover. Therefore, this embodiment also designs the inclination state of the spine and each application page to accurately simulate the book shape of the book-style navigation bar.

[0126] In an optional embodiment, if Figure 8 As shown, before step S17 of "sequentially splicing the front cover, the spine and the back cover", the method further includes:

[0127] S161. Determine an inclination angle formed by the spine and the back cover according to the first thickness and the number of the application images.

[0128] Based on the number of application images determined in the previous step and the thickness of a single page of the application inner page, in this step, Figure 3 As shown, the tilt angle formed by the spine and the back cover can be determined according to the preset book page simulation algorithm. Exemplarily, the more pages there are in the application, the greater the tilt angle of the simulated book-like navigation. In a specific example, the tilt angle θ is a linear function of the number of pages n in the application, that is, θ=nθ k , where θ k The preset tilt angle of an application page.

[0129] In another specific example, the tilt angle θ is a piecewise function of the number of application pages n. Considering that the single-page tilt angle corresponding to an application page is relatively small, this embodiment sets the tilt angle in segments. For example, when the application pages are 1 to 10 pages, the tilt angle is 1°, and when the application pages are 11 to 30 pages, the tilt angle is 5°. Through the above settings, the most realistic book simulation can be achieved.

[0130] S163 . Performing slope conversion on the cut page image corresponding to the book spine according to the tilt angle to form the book spine.

[0131] Furthermore, in this step, if Figure 7 As shown, in the flat state, the spine is rectangular, as shown in Figure 3 As shown, in the closed state, the book spine is an inclined quadrilateral. Therefore, according to the inclination angle θ determined in the previous step, the boundary where the back cover and the book spine intersect is used as the inclination boundary, and the rectangular book spine is tilted to form a three-dimensional book side.

[0132] S165: Determine an offset distance of the front cover relative to the back cover according to the tilt angle, so as to determine a cover position of the book-type navigation bar when no page is turned.

[0133] Exemplarily, there is an offset distance between the inner page of each application and the back cover, for example, the offset distance is 2 unit pixels, or the offset distance is multiple unit pixels. In this embodiment, the offset distance of each application can be determined based on the tilt angle, the number of applications and the thickness of the application page.

[0134] In this embodiment, the first thickness of the book-type navigation, that is, nD, can be determined according to the number of applications n and the thickness D of the application page. The inclination angle is θ. According to the Pythagorean theorem, the offset distance I between the top cover and the bottom back cover satisfies the tangent formula, that is, nD / I=tanθ.

[0135] Based on the overlapping inclined boundary of the back cover and the spine, the offset distance of each application is obtained. For example, the side edge of each application page is offset by two pixels. After the offset, the offset distance of each application page and the offset distance of the cover at the top can be determined, thereby realizing a book-like simulation of simulated navigation.

[0136] S3, acquiring an application image according to an application installed on the display terminal;

[0137] Exemplarily, there are many ways to obtain the application image. For example, for a non-locally installed application, the application has not been entered after installation. For this type of application, the page image may only display the icon and the application name.

[0138] In another example, a screenshot of each application is taken when each application is first started, and the screenshot is used as a page image. Through this setting, each application has its own screenshot book page, and based on the above steps, there is an offset distance between adjacent application pages, so that different applications have different visual effects, improving the navigation effect of the book-style navigation bar.

[0139] In another specific example, the application image of each application can be set according to the setting instruction of the user, so that the application image of the installed application can be acquired in advance.

[0140] S5. Generate an application inner page of the corresponding book-style navigation bar according to the application image.

[0141] like Fig. 9 and Fig.10 As shown, the book-style navigation bar of this embodiment includes application pages of multiple applications, and the application pages include a first page and a second page. In the folded state, the first page is close to the front cover, and the second page is close to the back cover. That is to say, the application page of this embodiment includes two pages, front and back, and the next application is displayed after turning the page in the manner of a book page. The front and back pages of this embodiment correspond to the same application, rather than two adjacent pages in the flat state corresponding to the same application. Through this setting, two different applications are displayed simultaneously in the flipping state.

[0142] In an optional embodiment, if Fig.11 As shown, step S5 "generating the application inner page of the book-style navigation bar according to the application image" further includes:

[0143] S51. Determine a third length of the application inner page in the first direction and a fourth length in the second direction according to the size of the cover.

[0144] Based on the process in the aforementioned step S1, the book cover wraps the application inner pages. In this embodiment, the size of the application inner pages can be determined according to the size of the book cover, for example Fig.10 As shown, the third length of the application inner page can be set to be consistent with the width of the cover in this direction, or consistent with the width of the back cover in this direction, and the fourth length of the application inner page can be set to be consistent with the length of the cover in the second direction, or consistent with the length of the back cover in this direction.

[0145] S53: Determine a second thickness of each of the application internal pages in the third direction according to a display size of the display terminal.

[0146] Exemplarily, based on the example in the aforementioned step S1, the thickness of the application inner page corresponding to each application is assumed to be D. Exemplarily, the thickness D of the application inner page is related to the pixel p of the display terminal, for example, D=mp, (m is a constant). That is, the second thickness is D.

[0147] S55: Convert the application image into an application inner page that satisfies the third length, the fourth length, and the second thickness.

[0148] Exemplarily, based on the process of step S3 "obtaining an application image according to the application installed on the display terminal", the main interface of the application can be captured by taking a screenshot. There may be a situation where the size of the application image generated by the screenshot is inconsistent. Therefore, this embodiment converts application images of different sizes into images of the same size so that they can be wrapped in a book cover and used as inner pages of the application.

[0149] In an optional embodiment, if Fig.12 As shown, step S55 "converting the application image into an application inner page that satisfies the third length, the fourth length and the second thickness" further includes:

[0150] 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 first length of the thickness of the spine;

[0151] In this step, the length of the application image is made consistent with the length of the page image by scaling, thereby accurately simulating a book-style navigation bar.

[0152] In this embodiment, what remains consistent is the length of the application image and the page image in the second direction. Since the page image forming the book cover also includes the spine, in the first direction, the length of the application image 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 the front cover in this direction, thereby obtaining an application inner page that is consistent with the size of the front cover or the back cover.

[0153] S553: ​​Split the application image into a first application image and a second application image by dividing the application image into a boundary with a center line of the side edge of the application image parallel to the spine.

[0154] In this embodiment, Fig. 9 As shown, one application corresponds to two application inner pages, so in this embodiment, the content of one application image is split so that both the first inner page and the second inner page can display the application content. Further, to ensure the display effect, the boundary is split by the center line parallel to the side of the spine, and the center line of the application image in the first direction is used as the axis to form a symmetrical first application image and a second application image.

[0155] S555: Set the image contents of the first application image and the second application image on two side pages of the same book page respectively.

[0156] like Fig. 9 As shown, the first application image is set on the front side of the same book page, and the second application image is set on the back side of the same book page, so as to realize the book page simulation of the book-style navigation bar.

[0157] Based on the above steps, after the application page of each application is formed, a subsequent process of superimposing multiple application pages is performed.

[0158] S7. Overlaying an inner page of an application with the same attribute and splicing it with the book cover to form a book-style navigation bar of the application corresponding to the attribute.

[0159] In an optional embodiment, if Fig.13 As shown, step S7 "the application inner page with the same attribute is superimposed as a book inner page, and is spliced ​​with the book cover to form a book-style navigation bar of the application corresponding to the attribute", further includes:

[0160] S71: Use the back cover as the back cover of the book-style navigation bar to overlay the inner pages of the application on the back cover.

[0161] S73, using the split boundary of each of the application images as a folded side edge close to the book spine.

[0162] Based on the aforementioned step S553, the application image is split into a first page image and a second page image. In this step, a plurality of application inner pages are superimposed using the split boundary between the first page image and the second page image as the folded side edge close to the spine.

[0163] S75. Overlay all application inner pages under the attribute on the back cover.

[0164] During the superposition process, application pages with the same attributes all use the split boundaries as folding sides and converge to one side of the spine. After superposition, application pages with thickness are formed.

[0165] S77, superimposing the cover on the application inner page away from the back cover, the boundary of the back cover close to the folded side edge, the boundary of the cover close to the folded side edge and the folded side edge form the book spine.

[0166] After the application pages with the same attributes are superimposed, the cover is superimposed on the application page located at the top, so that the cover and the cover wrap the superimposed application pages. After superposition, the page image corresponding to the spine covers the folded sides of all the application pages to form the spine.

[0167] In a specific example, this embodiment does not limit the stacking order of multiple application inner pages, that is, the application inner page close to the back cover is application 1, and the application inner page away from the back cover is application n. In another specific example, the application inner page close to the back cover is application n, and the application inner page away from the back cover is application 1.

[0168] In another specific example, the stacking order of pages in different applications can be determined according to the frequency of use, or the stacking order can be determined according to the letters of the name of each application, etc., which is not limited here.

[0169] In an optional embodiment, the method further includes:

[0170] An application inner page is added to the current book-style navigation bar according to the received adding instruction, and the first thickness of the book spine is re-determined according to the second thickness of the added application inner page.

[0171] When a new application is installed, an application inner page corresponding to the application is generated according to the properties of the new application and the process of the aforementioned steps S3 and S5, and then the thickness of the spine is redetermined according to the thickness of the new application inner page in the third direction. For example, the updated spine thickness is obtained by adding the second thickness of the new application inner page to the first thickness of the original spine.

[0172] In another optional embodiment, the method further includes.

[0173] The application inner page is deleted in the current book-type navigation bar according to the received deletion instruction, and the first thickness of the book spine is re-determined according to the second thickness of the deleted application inner page.

[0174] In this embodiment, when the user wants to delete an installed application, there is a corresponding application page in the book-style navigation bar for the application, and the application page must also be deleted in the book-style navigation bar. Then, the thickness of the spine is re-determined based on the thickness of the deleted application page in the third direction. For example, the updated spine thickness is obtained by subtracting the second thickness of the deleted application page from the first thickness of the original spine.

[0175] Based on the above embodiments, this embodiment makes the navigation of the navigation bar more accurate and improves the user experience by timely updating the application inner pages of the book-style navigation bar.

[0176] In an optional embodiment, the book cover of the book-style navigation bar is refreshed at a preset frequency. For example, the book cover changes according to the change of the dynamic wallpaper of the display terminal. The method of updating the book cover refers to the process of step S1 and is not repeated here. When the homepage wallpaper changes, the book cover will be dynamically changed accordingly, realizing the dynamic change of the navigation bar and improving the user experience.

[0177] In an optional embodiment, when an application of the display terminal is updated, for example, the application homepage of the application changes after the version of the application is upgraded, in this embodiment, the method also includes: obtaining an update log of the application installed on the display terminal, obtaining an application image and generating an application internal page after starting the updated application, and replacing the previous version of the application internal page with the updated application internal page.

[0178] Exemplarily, a version number, such as V1.1.0, is displayed on the application internal page generated based on the application image. When the application is upgraded in the background, the new version is V1.1.1. The device for generating the book-style navigation bar obtains the update information of the application. Since the update is a background update, the updated application may not be started. Therefore, this embodiment records the updated application, determines whether the application internal page has been updated, and then after the user starts the updated application, obtains the application image of the updated application, generates an updated application internal page with the updated application image, deletes the previous version of the application internal page, and inserts the updated application internal page into the position of the previous version.

[0179] Based on this step, the book-style navigation of this embodiment can not only realize the dynamic change of the book cover, but also realize the timely update of the application inner page of the book-style navigation, thereby improving the user experience.

[0180] In an optional embodiment, the book-style navigation bar is displayed in the display interface of the display terminal in the form of special effects during operations such as page turning, deleting application pages, adding application pages, and updating the order of application pages.

[0181] like Fig.14 As shown, taking deleting an application page as an example, the display interface will show the application page being torn off, and the dynamic effect of the torn application page flying to the far end. For example, taking deleting an application page as an example, the display interface will show the application page being torn off, and the dynamic effect of the torn application page flying to the far end, thereby improving the user experience through 3D motion effects.

[0182] The book-style navigation bar of this embodiment can bring together multiple applications in the same navigation, saving the problem of icon occupation of different applications. In addition, the book-style navigation bar of this embodiment occupies a smaller area and has less screen bottom obstruction, so that the management, browsing and display of all applications can be realized with a smaller layout. In addition, users do not need to turn pages through the scroll bar, which reduces the user's scrolling and page turning click operations. Furthermore, the book-style navigation bar of this embodiment can realize 3D scene switching effects through page turning effects, new addition effects, update effects, deletion effects, application startup special effects, etc., to enhance the immersive experience.

[0183] Another embodiment of the present invention provides a switching method of a book-style navigation bar based on the previous embodiment of the present invention, which is applied to the display terminal, such as Fig.15 As shown, the switching method includes:

[0184] S1301: Displaying the book-style navigation bar on the display interface of the display terminal according to the received display instruction, wherein the book-style navigation bar is located on a part of the display interface of the display terminal;

[0185] S1303, turning the page of the book-like navigation bar according to the received page turning instruction, and marking the displayed application inner page after turning the page, and displaying the marked application inner page on another part of the display interface;

[0186] S1305: Enter the currently displayed application page according to the received selection instruction.

[0187] By using the navigation switching method of this embodiment, users do not need to turn pages through the scroll bar, reducing the user's scrolling and page turning click operations. Furthermore, the book-style navigation bar of this embodiment can achieve 3D scene switching effects through page turning effects, adding effects, updating effects, deleting effects, application startup effects, etc., to enhance the immersive experience.

[0188] Exemplarily, the display terminal is a smart TV, and the user inputs a control instruction to the display terminal through a remote controller. The switching method is now described with a specific example:

[0189] S1301: Displaying the book-style navigation bar on the display interface of the display terminal according to the received display instruction, wherein the book-style navigation bar is located on a part of the display interface of the display terminal;

[0190] The remote controller operates according to the user's selection, for example, the user presses the navigation button of the remote controller, the remote controller outputs a control instruction, and the display terminal displays a book-style navigation bar according to the display instruction. Fig.16 As shown, the book-style navigation bar is set in a corner of the display interface of the display terminal.

[0191] When multiple applications with the same attributes are opened, such as application 2 and application 3, the two applications are integrated into the same book-style navigation bar through the book-style navigation bar. When multiple applications with different attributes are opened, such as application and setting program, the book-style navigation bars with different attributes are displayed on the display interface. The book-style navigation bar of this embodiment does not block the bottom of the entire display interface, reducing the occupancy rate of the display interface.

[0192] S1303: Turn the page of the book-like navigation bar according to the received page turning instruction, and mark the application inner page displayed after the page turning, and another part of the display interface displays the marked application inner page.

[0193] The remote controller outputs a page turning instruction according to the user's page turning operation. For example, the user presses and holds the remote controller to turn the page. The left key turns the page forward and the right key turns the page backward. The display terminal turns the page in the application in response to the page turning instruction. In a specific example, for example Figure 3 As shown, when the book-style navigation bar is displayed on the display interface, it is in a closed state without being flipped. Press and hold the right button on the remote control, for example Fig. 9 As shown, the right page turning effect will be called, such as Figure 4 As shown, the page is then displayed in a flat state of flipping. Exemplarily, the special effects of the display terminal are called, such as the Android Animation function custom Rotate3D, to achieve 3D page turning effects, and to turn pages through customized animation special effects.

[0194] like Fig. 9 As shown, the user presses the right button of the remote control once to turn the page from the cover to application 1. Pressing the right button again will turn the page to application 2. After turning the page to the last application, clicking the right button will prompt that the back cover has been turned. In another specific example, if the book-style navigation bar is displayed on the back cover, the user can click the left button of the remote control again to invoke the left-turning animation, turn the page to application n, continue to turn the page to the left, turn the page to application n-1, turn the page forward in sequence, turn to application 2, application 1 in sequence, until the cover is turned.

[0195] In this embodiment, when the page is turned to the current application page, the current application page will be marked. For example, a border is set on the edge of the current application page as a mark to mark the page turned to the current application page. Every time a page is turned, the application page turned to will be marked so that the user can clearly know the page turning position.

[0196] In this embodiment, Fig.16As shown, the book-style navigation bar is set in a corner of the display interface. For example, the position of the book-style navigation bar can be customized by the user, and the placement position can be selected by the system setting. You can choose the lower corner, lower right corner, upper left corner, upper right corner, etc., while the other part of the display interface is not idle, but displays the image of the currently identified application page for the user to clarify the function of the current application. In this example, the book-style navigation bar does not occupy the entire bottom of the display interface, which improves the display effect.

[0197] S1305: Enter the currently displayed application page according to the received selection instruction.

[0198] In this step, the remote controller outputs a selection instruction according to the user's selection operation, and the display terminal enters the currently displayed application page in response to the selection instruction.

[0199] For example, the remote control is provided with command buttons for entering different application pages, such as a signal source button, a setting button, a book page button, etc. The user can directly click the command button on the remote control to enter the corresponding application page. In another example, the application page entered can also be determined by the user's page turning operation and selection operation on the page turning button and the confirmation button, which will not be repeated here.

[0200] In an optional embodiment, step S1305 “entering the currently displayed application page according to the received selection instruction” includes:

[0201] In response to the selection instruction, the image content of the currently displayed application internal page is enlarged to the display interface, and the book-style navigation bar disappears on the display interface.

[0202] In this embodiment, based on the page turning in step S1303, each time the page is turned, the user can click the confirmation key to enter the application, and the remote control generates a selection instruction according to the key operation to enter the current application page. After confirmation, the image content of the application page will gradually enlarge, start the gradient animation effect, and then enlarge it to the entire screen. After the enlargement animation effect is started, the application is displayed on the entire display interface, and the navigation bar page will automatically disappear, realizing the transition from navigation selection to display.

[0203] In another optional embodiment, the method further includes: displaying a disappeared book-style navigation bar according to the received first navigation instruction, wherein the book-style navigation bar displays an application inner page corresponding to the current display interface, and the application inner page is marked.

[0204] In this embodiment, the remote control outputs navigation instructions according to the user's pressing operation. For example, the user presses and holds the navigation key of the remote control, and the display terminal responds to the navigation instruction to display the disappearing book-style navigation bar. The book-style navigation bar that just disappeared automatically will appear on the display interface, and the book-style navigation bar stays on the current application page, and the current page is in the identification state.

[0205] In another optional embodiment, the method further includes:

[0206] According to the received second navigation instruction, the displayed disappeared book-style navigation bar disappears again, and the display interface displays the application internal page marked by the book-style navigation bar.

[0207] In this embodiment, based on the aforementioned display of the navigation bar on the display interface according to the first navigation instruction, the user presses the navigation key of the remote control again and clicks the navigation bar a second time to output a second navigation instruction. According to the second navigation instruction, the book-style navigation bar displayed in the display interface disappears.

[0208] In an optional embodiment, the method further includes: according to the received adding instruction, displaying the special effect of inserting the application inner page into the book-like navigation bar on the display interface. In this embodiment, when the user installs a third-party application, the book page will be automatically added. For example, the added book page can be added to the front of the back cover of the last application inner page of the original book-like navigation bar, and the special effect of inserting the application inner page into the book page is displayed when adding the application inner page.

[0209] In another optional embodiment, according to the received deletion instruction, a special effect of deleting an application page from the book-like navigation bar is displayed on the display interface. Exemplarily, the user can call up a submenu by selecting a button on the remote control, and select Delete in the submenu to delete the current book page application. When deleting an application page, a special effect of deleting the application page from the book-like navigation bar is displayed.

[0210] In another optional embodiment, according to the received update instruction, the display interface displays the special effect of the sequential change of the application pages from the book-like navigation bar. The user selects to move the application page to the remaining position by controlling the buttons of the remote control. When the user selects to move, the book page enters the moving state. For example, when the left or right button of the remote control is clicked, the current application page will be moved forward or backward, and the special effect of page movement will be displayed.

[0211] The book-style navigation bar of this embodiment realizes 3D scene switching effects through the page turning effects, new adding effects, update effects, deletion effects, application startup special effects, etc. of the above embodiments, thereby enhancing the immersive experience.
