On the other hand, movement of items displayed in the display apparatus 200 may be controlled according to an input of a user through the control device 100 to cause a focus object to select or control the items. Such as: the user can control the items to move left and right together by the direction key on the control device 100, so as to enable the focus object to select and control the items while keeping the position of the focus object unchanged.

The identification form of the selector 43 is generally diversified. For example, the position of the focus object may be realized or identified by enlarging the item in fig. 2, by setting a background color of the item, or by changing a border line, a size, a color, a transparency, an outline, and/or a font of a text or an image of the focused item.

The GUI400 shown in FIG. 2 may be a schematic of an application under a certain category, such as the application under my love category. In some embodiments, the items 42 in FIG. 2 may include applications that are not installed to the display device 200. When the selector triggers an uninstalled application, i.e., selects and clicks an uninstalled application, GUI400 may switch to GUI500 shown in FIG. 3.

If the user triggers an uninstalled application at GUI400, GUI400 transitions to GUI 500. As shown in FIG. 3, GUI500 may pop up a window for GUI400, which may be provided with uninstalled application icons 51, uninstalled application control descriptions 52, first controls 53, and second controls 54. The uninstalled application icon 51 is an icon of an item selected in the GUI400, and the uninstalled application control description 52 is an explanation of the operation of the first control 53 and the second control 54. In some embodiments, the name of the first control 53 may be "Open" and the name of the second control 54 may be "Installl".

If the user triggers the first control 53, the GUI500 may switch to an application experience interface where the user may experience the functionality of the item, e.g., watching a video.

After the user experiences the uninstalled application, if the user likes the application, the user may return to the GUI500 from the application experience interface, trigger the second control 54 to install the uninstalled application into the display device 200, and after the second control 54 is triggered, install the uninstalled application onto the display device 200. The application may be displayed on a tv home page after the installation is successful, see fig. 4. GUI600 may be a tv home page which may display the installed application, and a prompt box 61 may pop up on GUI600 to prompt the application to be installed successfully.

Therefore, by setting the first control 53, the user enters the application experience interface of the application before installing the application to experience the application information such as the function and the interface style of the application, and compared with the prior art that the user can only know the application according to a few pictures, the embodiment can show more information of the application for the user, and is beneficial to more accurately judging whether the application is a favorite application; compared with the prior art that the user needs to install the application to experience the application, the application can be tested before the user installs the application, the application can not be installed if the user does not like the application, the problems that the user installs the application for experiencing the application and does not like the application to be uninstalled after the user experiences the application are solved, the time cost for the user to experience the application is reduced, and meanwhile, the occupation of the storage space of the display device can be reduced.

Since the user's preferences and the content of the application typically change dynamically, after an application has been installed for a period of time, the user may no longer like or need the application and the application needs to be uninstalled. The user may trigger an installed item that needs to be uninstalled in GUI600, at which point GUI600 may switch to GUI700 shown in FIG. 5.

Referring to fig. 5, GUI700 may pop up a window for GUI600 that may be provided with an installed application icon 71, an installed application control caption 72, a third control 73, and a fourth control 74. The installed application icon 71 is an icon of an application selected in the GUI400, and the installed application control description 72 is an explanation of the operation of the third control 73 and the fourth control 74. In some embodiments, the name of the third control 73 may be "Open" and the name of the fourth control 74 may be "Uninstall".

If the user triggers the third control 73, the GUI700 may switch to the application interface of the item where the user may use the full functionality of the item. If the user triggers the fourth control 74, the application may be unloaded.
