In order to overcome the disadvantages of screen projection in the mirror image mode, continue to refer to FIG. 1. When the screen projection is in the mirror image mode, the desktop screen projection of the electronic device 200 can be stretched, zoomed and cut according to the size of the screen of the display device 100. , but this will cause problems such as deformation or incomplete display of the projected desktop page displayed on the display device 100 .

In addition, a screen projection method in computer mode has also been developed. As shown in FIG. 2 , when using the computer mode to cast a screen, the desktop on the electronic device 200 will be transformed into a style similar to a computer desktop to fill the screen of the display device 100 (that is, the receiving device for screen projection), and all the screens on the electronic device 200 The applications are all hidden in the application drawer in the area b1 in the lower left corner of the desktop in the computer mode. After clicking the application drawer in the area b1, the applications on the electronic device 200 can be displayed in the area b2. Wherein, when using the computer mode for screen projection, the electronic device 200 and the display device 100 are relatively independent, and the two can be used separately. It can be seen from FIG. 2 that the screen projection method in the computer mode is to directly and bluntly change the desktop of the electronic device 200 into a computer desktop.

Exemplarily, the resident content displayed on the display device 100 may be displayed on the display screen of the display device 100 except for the N desktop pages, for example, displayed in the middle of the display screen of the display device 100 and located at lower area.

For example, when there are only two desktop pages in the electronic device 200, as shown in (A) of FIG. The desktop page is the desktop page currently displayed on the electronic device 200, and the desktop page corresponding to the number "2" is the next desktop page after switching from the currently displayed desktop page on the electronic device 200, and the contents in the areas Z1 and Z2 are normal resident content. Under the source interface of the electronic device 200 shown in (A) of FIG. The display device 100 may display an interface as shown in (B) of FIG. 4 . In the interface shown in (B) of Figure 4, the desktop page corresponding to the number "1" corresponds to the desktop page corresponding to the number "1" in (A) of Figure 4, and in (B) shown in Figure 4 The desktop page corresponding to the number "2" in the interface corresponds to the desktop page corresponding to the number "2" in Figure 4 (A), and the content displayed in area Z3 in the interface shown in Figure 4 (B) is the same as The contents displayed in areas Z1 and Z2 in (A) of FIG. 4 correspond to each other. Comparing (A) and (B) of FIG. 4, it can be seen that after screen projection, the content and typesetting contained in each desktop page displayed on the display device 100 correspond to the desktop page on the electronic device 200 The content and layout of the desktop page are the same, so that the desktop page displayed on the display device 100 can conform to the user's usage habits on the electronic device 200, thereby facilitating the user to operate on the display device 100 and improving the user experience. In addition, the resident content on the electronic device 200 can also be displayed on the display device 100 at the same time, that is, the content displayed in the area Z3 on the display device 100, so as to better conform to the user's usage on the electronic device 200 after screen projection. Habit. Wherein, in (B) of FIG. 4 , the resident content displayed by the display device 100 is located below the N desktop pages displayed by the display device 100 and is located in the center of its display area. Of course, in (B) of FIG. 4 , the resident content can also be displayed in other areas, for example, displayed in the lower left or lower right of the display area of the display device 100. At this time, the resident content is displayed on the display device 100 displayed below the desktop page; in addition, the resident content may also be displayed above the display area of the display device 100, which may be determined according to actual conditions.

For example, when there are three desktop pages in the electronic device 200, as shown in (A) of FIG. 5 , which is the source interface of the electronic device 200, wherein the desktop page corresponding to the number "1" is The desktop page currently displayed on 200, the desktop page corresponding to the number "2" is the next desktop page after switching from the desktop page currently displayed on the electronic device 200, and the desktop page corresponding to the number "3" is the desktop page corresponding to the number "2". The next desktop page after the corresponding desktop page is switched; in (A) of Figure 5, a resident content is displayed below each desktop page, and each resident content includes phone applications, SMS applications, browsing browser app and camera app. Under the source interface of the electronic device 200 shown in (A) of FIG. The display device 100 may display an interface as shown in (B) of FIG. 5 . Wherein, in (B) of FIG. 5 , the position of the resident content displayed by the display device 100 is similar to the position of the resident content in (B) of FIG. 4 described above, and will not be repeated here. .

In some embodiments of the present application, when displaying N desktop pages, the display device 100 can respectively enlarge the contents of the N desktop pages according to the size of its display screen, so that the size of the content displayed on the display device 100 Adapt to the size of the display screen of the display device 100 . For example, when the display device 100 is a TV and the electronic device 200 is a mobile phone, since the size of the display screen of the TV is much larger than that of the mobile phone, if the screen projection is performed on the mobile phone, every If the size of the content in each desktop page is not displayed, the desktop page displayed on the TV screen will be too small, and there will be a large area of blank space on the TV screen, resulting in a low utilization rate. So in this case, when the TV is displaying the content of the desktop page on the mobile phone, the content in the N desktop pages can be respectively enlarged according to a certain ratio, so that the size of the content displayed on the display screen of the TV is the same as that of the TV Adapt to the size of the display screen, enhance the visual experience and operating experience.

In some embodiments of the present application, the value of N may be determined according to the size of the display screen of the display device 100 . Exemplarily, the corresponding relationship between the value of N and the size of the display screen of the display device 100 can be preset, so that the value of N can be known after the size of the display screen of the display device 100 is known. For example, when the size of the display screen of the display device 100 is between 7 inches and 15.6 inches, the value of N can be 2; when the size of the display screen of the display device 100 is greater than 15.6 inches, the value of N can be 3 , and so on, which may be determined according to the actual situation, and are not limited here.

In some embodiments of the present application, when the display device 100 displays N desktop pages, when the display screen of the display device 100 is in the landscape mode, the horizontal size of the display screen of the display device 100 is larger, so at this time the display device The N desktop pages displayed at 100 can be arranged horizontally in sequence. For example, continue to refer to FIG. 4 (B) and FIG. 5 (B), the display screen of the display device 100 is currently in landscape mode, so the N desktop pages displayed by the display device 100 can be arranged horizontally in turn.

When the display screen of the display device 100 is in the portrait mode, the horizontal size of the display screen of the display device 100 is smaller, so the N desktop pages displayed by the display device 100 can be arranged vertically in sequence. For example, as shown in FIG. 6, if the display screen of the display device 100 is in the landscape mode under the interface shown in (A) of FIG. 6, then when the display screen of the display device 100 is switched from the landscape mode to the portrait mode , the display interface on the display device 100 can be switched to the interface shown in (B) of FIG. 6 . Wherein, in (A) and (B) of FIG. 6 , the resident content displayed by the display device 100 is located below the displayed desktop page and in the center of its display area.

As a possible implementation, when the display screen of the display device 100 is in the portrait mode, the display device 100 may also vertically display a desktop page, and the desktop page may be the interface currently displayed on the display screen of the electronic device 200 . In addition, when the display screen of the display device 100 is switched from the landscape mode to the portrait mode, the desktop page displayed on the screen of the display device 100 at this time may be the desktop page ranked first in the landscape mode. For example, as shown in FIG. 7, if under the interface shown in (A) of FIG. 7, the display screen of the display device 100 is in landscape mode, then when the display screen of the display device 100 is switched from landscape mode , the display interface on the display device 100 may be switched to the interface shown in (B) of FIG. 7 , and the interface shown in (B) of FIG. 7 may include a desktop page and a resident content.

As another possible implementation, when the display screen of the display device 100 is in the portrait mode, if the horizontal size of the display screen of the display device 100 still supports displaying multiple desktop pages, the display device 100 can still Multiple desktop pages are displayed in landscape orientation on the display. For example, as shown in FIG. 8 , two desktop pages are displayed on the display screen of the display device 100 at this time, wherein the number "1" corresponds to one desktop page, and the number "2" corresponds to one desktop page. In addition, continuing to refer to FIG. 8 , resident content may also be displayed below the desktop page shown in FIG. 8 .

In addition, in this case, after the display device 100 displays multiple desktop pages horizontally on its display screen, if there are still desktop pages that can be displayed at this time, and there is a display space in the vertical direction of the display screen, the display device 100 100 may also continue to display the remaining desktop pages in the corresponding display space. For example, as shown in FIG. 9, at this time, three desktop pages are displayed on the display screen of the display device 100, two desktop pages are displayed horizontally on the upper half of the display screen, and one desktop page is displayed on the lower half of the display screen. . Of course, when the display screen of the display device 100 is in the landscape mode, such a display mode may also be adopted, which may be determined according to actual conditions, and is not limited here.

In some embodiments of the present application, when displaying the desktop page projected by the electronic device 200 on the display device 100, in order to make full use of the display space of the display screen of the display device 100, the display screen of the display device 100 may also display Icons of applications recently opened by the user on the display device 100, and/or icons of applications recently opened by the user on the electronic device 200 are displayed, so that the user can quickly find the applications opened recently. The area where the icon of the application recently opened by the user is displayed on the display screen of the display device 100 may be determined according to actual conditions, and is not limited here. Exemplarily, the display device 100 may, but is not limited to, display icons of applications recently opened by the user side by side with resident content. For example, as shown in FIG. 10 , icons of applications recently opened by the user may be displayed at the bottom of the display screen of the display device 100 and near the central area Z4, where the area Z4 is consistent with the resident content displayed on the display device 100. displayed side by side.

After the electronic device 200 finishes projecting the screen to the display device 100 , the user can perform operations on the display device 100 . For example: switching desktop pages, etc.

In some embodiments of the present application, when the user switches interfaces on the display device 100, the number of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at one time cannot be outnumbered by the number of desktop pages on the electronic device 200. When the total number of the quantity is divisible, if the interface of the number of desktop pages of the electronic device 200 that can be displayed by the display screen of the display device 100 is switched every time the interface is switched, then when switching to the last desktop page, the screen of the display device 100 The display will go blank. At this time, among the (N+M) desktop pages included in the source interface acquired by the display device 100 , the value of M may be greater than or equal to 1.

For example, if the number of desktop pages of the electronic device 200 that can be displayed by the display screen of the display device 100 at one time is 2, the total number of desktop pages on the electronic device 200 is 5, and two pages are switched every time the interface is switched. Desktop page; at this time, as shown in (A) of Figure 11, the user slides to the left with finger F on the display screen of the display device 100, and then the display interface on the display screen of the display device 100 is changed from displaying "1", " 2" desktop page is switched to display "3" and "4" desktop pages, that is, the interface shown in (B) of FIG. 11 is displayed. Next, the user slides left on the display screen of the display device 100 with the finger F again, and then the display interface on the display screen of the display device 100 switches from displaying "3" and "4" desktop pages to displaying "5" and " Empty" desktop page, the interface shown in (C) of Figure 11 is displayed. It can be understood that the content in the dotted line box except "empty" in Fig. 11 is the interface to be switched, and they are described here only for the convenience of explanation; for the dotted line box corresponding to the word "empty", you can It may actually exist, or it may not exist (in this case, the area may be a blank area), which may be determined according to the actual situation, and is not limited here.

Further, in order to avoid the above-mentioned problem of a blank interface when the interface is switched on the display device 100, the embodiment of the present application provides a more dynamic solution.

Specifically, when the number X of desktop pages to be switched is greater than or equal to the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at one time, when the user switches interfaces on the display device 100, at this time , the display device 100 may obtain the interface switching instruction issued by the user, and then, Y desktop pages to be switched may be moved on the display screen of the display device 100, that is, the desktop page may be switched. When the number X of desktop pages to be switched is less than the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at one time, when the user switches interfaces on the display device 100, the display device 100 can After the interface switching instruction issued by the user is obtained, X desktop pages to be switched can be moved on the display screen of the display device 100 , that is, the desktop page can be switched. In this way, the above-mentioned problem of blank space on the display interface existing in the switching interface on the display device 100 can be solved. In some embodiments, the number Y may be equal to the number N of desktop pages that the display device 100 can simultaneously display.

For example, when X≥Y, continue referring to FIG. 11 , in (A) of FIG. 11 , desktop pages “1” and “2” are displayed on the display device 100, and the desktop pages to be switched are “3”, "4", "5" desktop pages, the number X of desktop pages to be switched at this time is 3, and the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at one time is 2. Since X≥Y, when the user switches the interface with finger F on the display device 100, the display screen of the display device 100 can move 2 desktop pages, that is, the interface shown in (B) of FIG. 11 is displayed.

When X<Y, as shown in Figure 12, in (A) of Figure 12, "3", "4" desktop pages are displayed on the display device 100, and the desktop pages to be switched to the left are "1", " 2" desktop page, the desktop page to be switched to the right is "5" desktop page, if the user switches the interface to the right at this time, the number X of the desktop page to be switched is 1, and the display screen of the display device 100 can display at one time The number Y of desktop pages of the electronic device 200 is two. Since X<Y, when the user switches the interface with the finger F on the display device 100, one desktop page can be moved on the display screen of the display device 100, that is, the interface shown in (B) of FIG. 12 is displayed. Wherein, the interface displayed on the display device 100 after switching (B) of FIG. 11 to (C) of FIG. 11 , and the interface displayed on the display device 100 after switching (A) of FIG. Comparing the interfaces, it can be seen that the blank interface that appeared in (C) of FIG. 11 does not appear in (B) of FIG. 12 .

As a possible implementation, in addition to solving the problem of the blank interface when switching the interface on the display device 100 through the above method, it is also possible to switch Y desktop pages when the above-mentioned X is less than Y, but after switching, it can adapt to Permanently adjust the display position of the switched desktop page, the spacing and/or size of different contents contained in the desktop page, etc., so that the switched desktop page matches the size of the display screen of the display device 100 .

In some embodiments of the present application, the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at one time can also be replaced by the desktop that can be switched each time the interface is switched by the user setting or system preset number of pages.

As a possible implementation manner, the number of desktop pages that can be switched each time the desktop pages are switched may be determined according to the sliding parameters of the user on the display screen of the display device 100 . At this time, after the display device 100 acquires the interface switching issued by the user, it may acquire the sliding parameter corresponding to the interface switching command, and determine the number of desktop pages to be switched by the sliding parameter, and then switch the desktop page. Exemplarily, the sliding parameters may include sliding distance and/or sliding speed and the like. In some embodiments, the sliding parameters may be referred to as touch parameters.

Specifically, FIG. 13 shows a schematic diagram of steps for determining the number of desktop pages that can be switched each time the interface is switched based on the sliding parameters of the user on the display screen of the display device 100 . Wherein, in FIG. 13 , the display screen of the display device 100 may be a touch screen, and the sliding parameter is a sliding distance. As shown in Figure 13, the following steps are included:

First, in S1301, the display screen on the display device 100 may collect an initial position and an end position of a sliding operation performed by the user. When the user performs a sliding operation, when the user touches the display screen of the display device 100 , the display screen of the display device 100 can obtain the position, that is, obtain the initial position. When the user ends the sliding operation, the display screen of the display device 100 can know the position when the user ends the sliding operation, that is, obtain the end position.

Next, in S1302, the sliding distance for the user to perform the sliding operation may be calculated from the initial position and the end position.

Next, in S1303, the sliding distance is compared with a preset sliding distance threshold, and a size between the sliding distance and the preset sliding distance threshold is determined.

Finally, in S1304, when the sliding distance is greater than the sliding distance threshold, it is determined that the number of desktop pages that can be switched each time the desktop page is switched is m1. In S1305, when the sliding distance is less than or equal to the sliding distance threshold, it is determined that the number of desktop pages that can be switched each time the desktop page is switched is m2. Wherein, m1 and m2 can be set according to actual conditions, and are not limited here.

It is understandable that the sliding distance in Figure 13 can also be replaced by other sliding parameters, such as sliding speed, etc.; in addition, the method of obtaining sliding parameters can also be replaced by other methods, which are not limited here, and the replaced The scheme is still within the protection scope of the present application.

After the electronic device 200 completes screen projection to the display device 100, the user can not only operate on the display screen of the display device 100 and the display screen of the electronic device 200 respectively, but also connect the display screen of the display device 100 and the Bind the display screens of the two display screens to form a linked desktop, so that more desktop pages on the electronic device 200 can be displayed at one time, thereby reducing the number of times the user switches desktop pages, and allowing the user to Directly access to the desktop page it needs, improving the efficiency of using two devices when they work together. Wherein, the user may bind the display screen of the display device 100 and the display screen of the electronic device 200 through a specific trigger operation. Exemplarily, the triggering operation may include one or more of: controlling the collision between the display device 100 and the electronic device 200 , cross-screen pinching operation, voice control and other operations. Exemplarily, the cross-screen pinch operation may be a multi-finger cross-screen pinch operation, for example, two fingers, three fingers, etc., which is not limited here.

For example, as shown in (A) of FIG. 14 , the desktop pages “d1” and “d2” are being displayed on the display device 100, and the desktop page “1” is being displayed on the electronic device 200, wherein the “1” desktop page The next desktop page is "2" desktop page, and the next desktop page of "2" desktop page is "3" desktop page. In the situation shown in (A) of FIG. 14 , the user controls the electronic device 200 to collide with the display device 100 , and then the binding between the display device 100 and the electronic device 200 is completed, and the display screens of the two can be linked. After the display device 100 and the electronic device 200 are bound, as shown in (B) of FIG. The "d1" and "d2" desktop pages are switched to display the "2" and "3" desktop pages.

As shown in (A) of Figure 15, the desktop pages "d1" and "d2" are being displayed on the display device 100, and the desktop page "1" is being displayed on the electronic device 200, wherein the next desktop page of the "1" desktop page is "2" desktop page, and the next desktop page of "2" desktop page is "3" desktop page. In the situation shown in (A) of FIG. 15 , the user touches the display screen of the display device 100 with one finger of the hand F, touches the display screen of the electronic device 200 with the other finger of the hand F, and executes the finger After the pinching operation, the binding between the display device 100 and the electronic device 200 is completed, and the display screens of the two can be linked. After the display device 100 and the electronic device 200 are bound, as shown in (B) of FIG. The "d1" and "d2" desktop pages are switched to display the "2" and "3" desktop pages.

After the display interface on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 form a linked desktop, when the user switches the interface on the display device 100 or the electronic device 200, the display of the display device 100 and the electronic device 200 The display interface on the screen will be switched in conjunction. In other words, when the user switches the interface on the display device 100, the interface on the electronic device 200 also follows the switching at the same time; when the user switches the interface on the electronic device 200, the interface on the display device 100 also follows the switching at the same time, thus In order to achieve the effect of linkage switching, it is convenient for users to control, and the display effect and user experience are improved. Exemplarily, after the electronic device 200 obtains the interface switching instruction issued by the user, the electronic device 2090 may send the interface switching instruction to the display device 100, so that the two can perform interface switching at the same time; after that, the display device 100 may respond to the interface Switch command, switch desktop page. Wherein, after the display device 100 and the electronic device 200 switch the desktop pages, the desktop pages displayed by the two are different.

For example, as shown in (A) of FIG. 16 , the display interface on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 form a linked desktop. Wherein, the display screen of the electronic device 200 displays "1" desktop page, the display screen of the display device 100 displays "2" desktop page, and the desktop pages to be switched are "4" and "5" desktop pages. In (A) of FIG. 16 , the user slides to the left with hand F on the display screen of the electronic device 200 , and then a desktop page switch appears. Since the display screen on the electronic device 200 can only display one desktop page at a time, when the user switches desktop pages on the display screen of the electronic device 200 , one desktop page can be switched at a time on the display screen of the electronic device 200 . As shown in (B) of FIG. 16 , after the desktop page is switched, the display screen of the electronic device 200 may display “2” desktop pages, and the display screen of the display device 100 may display “3” and “4” desktop pages.

As shown in (A) of FIG. 17 , the display interface on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 form a linked desktop. Wherein, the display screen of the electronic device 200 displays "1" desktop page, the display screen of the display device 100 displays "2" desktop page, and the desktop pages to be switched are "4" and "5" desktop pages. In (A) of FIG. 17 , the user slides to the left with the hand F on the display screen of the display device 100 , after which a desktop page switch appears. Since the display screen on the display device 100 can display two desktop pages at a time, when the user switches desktop pages on the display screen of the display device 100 , two desktop pages can be switched at a time on the display screen of the display device 100 . As shown in (B) of FIG. 17 , after the desktop page is switched, the display screen of the electronic device 200 may display "3" desktop page, and the display screen of the display device 100 may display "4" and "5" desktop pages.

It can be understood that in FIG. 16 and FIG. 17 , when switching desktop pages, the number of desktop pages switched each time can be the switching rules described above, which will not be repeated here.

Further, after the desktop page displayed on the display screen of the display device 100 and the desktop page displayed on the display screen of the electronic device 200 form a linked desktop, due to the fact that the user moves the display device 100 or the electronic device 200, when After the user moves the display device 100 or the electronic device 200, the positional relationship between the two will change, and at this time, the arrangement order of the desktop pages in the linked desktop composed of the two will also change, resulting in the desktops in the linked desktop at this time. The sorting order of the pages does not conform to the user's usage habits. Therefore, after the user moves the display device 100 or the electronic device 200, the display device 100 and/or the electronic device 200 can adjust the combined form of the desktop pages in the linked desktop according to the relative positional relationship between the two, so that the desktop in the linked desktop The combined form of the page conforms to the user's usage habits, thereby improving the user experience.

For example, as shown in (A) of FIG. 18 , the desktop page displayed on the display screen of the display device 100 and the desktop page displayed on the display screen of the electronic device 200 form a linked desktop. Wherein, the display screen of the electronic device 200 displays a "1" desktop page, and the display screen of the display device 100 displays a "2" desktop page. In (A) of FIG. 18 , the user can move the electronic device 200 from the left side to the right side of the display device 100 . Afterwards, as shown in (B) of FIG. 18 , the electronic device 200 senses that its relative position with the display device 100 has changed, and moves to the other side of the display device 100 . At the same time, the display screen of the display device 100 displays "2" and "3" desktop pages. Therefore, at this time, the desktop page displayed on the display screen of the electronic device 200 can be switched from the last desktop page displayed on the display screen of the display device 100 to the next desktop page of the desktop page, that is, the desktop page displayed by "1" Page switch to "4" desktop page. It can be understood that when the user moves the display device 100, the display device 100 and/or the electronic device 200 can adjust the combined form of the desktop pages in the linked desktop according to the relative positional relationship between the two. The adjustment methods for moving the electronic device 200 are the same, and will not be repeated here.

In some embodiments of the present application, after displaying N (N≥2) desktop pages on the display screen of the display device 100, the user can perform N desktop pages and (N-k) desktop pages on the display screen of the display device 100. Switch between pages to meet the needs of users in different scenarios; wherein, k is a positive integer, and 0<k<N.

For example, as shown in (A) of FIG. 19 , two desktop pages are displayed on the display screen of the display device 100 . Wherein, in (A) of FIG. 19 , application 1 to application 20, and application A to application D can form a desktop page; application 21 to application 40, and application A to application D can form a desktop page. In (A) of FIG. 19 , the display device 100 may display applications 1 to 20, and application A To the desktop page that application D can compose, that is, the interface shown in (B) of FIG. 19 .

It is understandable that after the user switches the N desktop pages to (N-k) desktop pages, the display device 100 can adaptively adjust the spacing between the contents contained in the (N-K) desktop pages, so that the switching The content contained in the last desktop page is maximized to cover the display screen of the display device 100, avoiding a large blank area on the display screen of the display device 100, and improving the display effect. For example, continue to refer to FIG. 19, after switching the two desktop pages in (A) of FIG. 19 to one desktop page in (B) of FIG. 19, in (B) of FIG. The spacing between the applications is adjusted so that applications 1 to 20 can maximize the display screen of the display device 100 .

It is understandable that, for the desktop page to be displayed after switching, it may be displayed based on a preset switching rule, which may be determined according to actual conditions, and is not limited here. Exemplarily, the preset switching rule may be: after the N desktop pages are switched to (N-k) desktop pages, the first (N-K) of the N desktop pages are displayed on the display screen of the display device 100 The desktop pages, or, display the last (N-K) desktop pages among the N desktop pages; after the (N-k) desktop pages are switched to N desktop pages, what is displayed on the display screen of the display device 100 is (N-K K desktop pages before the first desktop page among the (N-K) desktop pages are displayed, or K desktop pages after the last desktop page (that is, the (N-K)th desktop page) among the (N-K) desktop pages are displayed.

In some embodiments of the present application, when the desktop page is switched on the display screen of the display device 100, the user may switch by issuing an operation command, for example, switch by voice command, switch by manual operation, and so on.
