< method example >

Fig. 2 illustrates a control method according to an embodiment of the present disclosure, where the control method may be implemented by a head-mounted display device, or may be implemented by a control device independent of the head-mounted display device and the head-mounted display device, or may be implemented by a cloud server and the head-mounted display device, where the head-mounted display device may be AR glasses.

As shown in fig. 2, the control method of this embodiment may include steps S2100 to S2300 of:

in step S2100, in the running process of the desktop environment, in response to a trigger event that a second Activity is started in the first Activity, it is detected whether to designate identification information of a virtual screen for the second Activity.

In this embodiment, a desktop Launcher of the head-mounted display device is referred to as an AR Launcher, the AR Launcher is automatically started when the head-mounted display device is turned on, a desktop environment of the head-mounted display device starts to run, and after a user wears the head-mounted display device, the head-mounted display device displays the desktop environment within a sight range of the user. It will be appreciated that the desktop environment is typically a 3D desktop environment.

In this embodiment, during the running process of the 3D desktop environment, the 3D desktop environment may create a plurality of virtual screens, and after the virtual screens are created, the head-mounted display device may specify an application running on each virtual screen, for example, may specify an Activity of the application running on each virtual screen, that is, the Activity of the application is run on the virtual screen. Other Activities of the application and activities of other applications that are interactively launched on the virtual screen need to be displayed on the virtual screen.

The first Activity may be an Activity in the first application, and the second Activity may be an Activity in the first application or an Activity in the second application. For example, the first application may be a chat application and the second application may be a browser application.

Example 1, taking an application to which a first Activity belongs as a chat application and an application to which a second Activity belongs as a browser application as an example, the first Activity is normally displayed on the virtual screen 1, where link information is displayed on the first Activity, where a user clicks link information (the link information indicates the second Activity in the browser application), and the head-mounted display device may receive a trigger event for starting the second Activity at the first Activity, and detect whether identification information of the virtual screen is specified for the second Activity in response to the trigger event.

Example 2, taking the example that the first Activity and the second Activity both belong to chat applications, the first Activity is normally displayed on the virtual screen 1, where a toggle control is displayed on the first Activity, where a user clicks the toggle control (the toggle control indicates the second Activity in the chat applications), and the head-mounted display device may receive a trigger event for starting the second Activity at the first Activity, and detect whether identification information of the virtual screen is specified for the second Activity in response to the trigger event.

In a specific embodiment, in response to a triggering event that the second Activity is started in the first Activity in step S2100, detecting whether to specify the identification information of the virtual screen for the second Activity may further include steps S2110 to S2130:

step S2110, responding to a trigger event for starting the second Activity at the first Activity, and acquiring a starting parameter when the second Activity is started.

Wherein the startup parameters include a first parameter. The first parameter is used to specify identification information of the virtual screen running the second Activity, where the identification information may be a virtual screen id, and it may be null, indicating that identification information of the virtual screen is not specified for the second Activity. The starting parameters further include a second parameter and a third parameter, the second parameter is used for recording package name information of an application to which the first Activity invoking the second Activity belongs, and the second parameter may also be referred to as package name information of a source application invoking the second Activity, namely, a callingPackage, which cannot be empty normally. The third parameter is used for recording package name information of the application to which the second Activity belongs, and the package name information cannot be empty normally.

Continuing with example 1 above, the head-mounted display device, in response to a trigger event that a second Activity is started at the first Activity, acquires a first parameter, a second parameter, and a third parameter, where the first parameter may be null or may be identification information of the virtual screen 1, the second parameter records package name information of the chat application, and the third parameter records package name information of the browser application.

Continuing with example 2 above, the head-mounted display device obtains a first parameter, a second parameter and a third parameter in response to a trigger event that a second Activity is initiated at the first Activity, where the first parameter may be null or may be identification information of the virtual screen 1 (e.g., virtual screen 1 id), the second parameter records packet name information of the chat application, and the third parameter records packet name information of the chat application.

Step S2120, determining that the identification information of the virtual screen specified for the second Activity is detected under the condition that the identification information of the virtual screen running the second Activity is specified in the first parameter.

Continuing with examples 1 and 2 above, where the first parameter is identification information of the virtual screen 1 (e.g., id of the virtual screen 1), indicating that the identification information of the virtual screen is specified for the second Activity, it is determined that the identification information of the virtual screen specified for the second Activity is detected.

Step S2130, in a case that the identification information of the virtual screen running the second Activity is not specified in the first parameter, determining that the identification information of the virtual screen not specified for the second Activity is detected.

Continuing with examples 1 and 2 above, in the case where the first parameter is null, indicating that the identification information of the virtual screen is not specified for the second Activity, it is determined that the identification information of the virtual screen specified for the second Activity is not detected.

In the process of executing step S2100 during the running of the desktop environment, in response to a trigger event that the second Activity is started in the first Activity, after detecting whether the identification information of the virtual screen is specified for the second Activity, the following steps are performed:

step S2200, under the condition that the identification information of the virtual screen is not specified for the second Activity, querying a first hash table according to the package name information of the application to which the first Activity belongs, and obtaining the identification information of the virtual screen corresponding to the package name information of the application to which the first Activity belongs as target identification information.

The keyword key of the first hash table is package name information of any application installed in the head-mounted display device, and the hash value corresponding to the keyword is identification information (for example, a virtual screen id) of a virtual screen on which the any application is running. As can be understood, the key and its corresponding hash value in the first hash table are in a one-to-one relationship.

In this embodiment, if the identification information of the virtual screen is not specified for the second Activity, the identification information of the virtual screen corresponding to the application to which the first Activity belongs may be searched in the first hash table as the target identification information according to the package name information (containment package) of the source application calling the second Activity, that is, the package name information of the application to which the first Activity belongs.

Continuing with examples 1 and 2 above, if the identification information designating the virtual screen for the second Activity is not detected, the virtual screen id corresponding to the package name information of the chat application, that is, the id of the virtual screen 1, can be searched from the first hash table.

In step S2200, when the identification information of the virtual screen is not specified for the second Activity, querying a first hash table according to the package name information of the application to which the first Activity belongs, obtaining the identification information of the virtual screen corresponding to the package name information of the application to which the first Activity belongs, and entering, after the identification information is used as target identification information:

step S2300, operating the second Activity in the target virtual screen indicated by the target identification information.

In this embodiment, the head-mounted display device may operate the second Activity in the virtual screen according to the virtual screen indicated by the identification information of the virtual screen corresponding to the package name information of the application to which the first Activity belongs, so as to implement normal operation of the second Activity in the virtual screen, thereby achieving normal display of Activity interaction in the virtual screen.

In one embodiment, after executing step S2200 above, in a case that identification information of a virtual screen is not specified for the second Activity, querying a first hash table according to package name information of an application to which the first Activity belongs, and obtaining identification information of the virtual screen corresponding to the package name information of the application to which the first Activity belongs, as target identification information, the control method of the embodiment of the present disclosure further includes:

under the condition that the package name information of the application to which the second Activity belongs is different from the package name information of the application to which the first Activity belongs, recording the target identification information and the package name information of the application to which the second Activity belongs into the first hash table and the second hash table; or,

and under the condition that the package name information of the application to which the second Activity belongs is the same as the package name information of the application to which the first Activity belongs, performing no operation on the first hash table and the second hash table.

The keyword key of the second hash table is identification information (for example, a virtual screen id) of any virtual screen created in the head-mounted display device, and the hash value corresponding to the keyword is packet name information of an application supported and run by the any virtual screen. It can be understood that the key and its corresponding hash value in the second hash table are in a one-to-many relationship.

In this embodiment, after detecting that identification information of a virtual screen is not specified for the second Activity and after querying identification information of a virtual screen corresponding to package name information of an application to which the first Activity belongs from the first hash table, it needs to further determine whether the application to which the first Activity belongs and the application to which the second Activity belongs are the same application, if the application is the same application, no processing is performed on the first hash table and the second hash table, and if the application is different, the target identification information and the package name information of the application to which the second Activity belongs are recorded in the first hash table and the second hash table.

In one embodiment, the control method according to the embodiment of the present disclosure further includes: and under the condition that the identification information of the virtual screen is specified for the second Activity, running the second Activity in the virtual screen indicated by the identification information.

Continuing with examples 1 and 2, when the first parameter is id of the virtual screen 1, indicating that the identification information of the virtual screen is specified for the second Activity, and determining that the identification information of the virtual screen specified for the second Activity is detected, the second Activity can be directly run on the virtual screen 1.

According to the embodiment of the application, if the starting parameters of the second Activity include the identification information for specifying the virtual screen for the second Activity, the second Activity can be directly operated on the corresponding virtual screen.

In one embodiment, the control method according to the embodiment of the present disclosure further includes: under the condition that the identification information of the virtual screen is appointed for the second Activity, if the package name information of the application to which the second Activity belongs is not located in a first hash table and a second hash table, recording the identification information of the virtual screen appointed for the second Activity and the package name information of the application to which the second Activity belongs to the first hash table and the second hash table.

In this embodiment, if it is detected that the identification information of the virtual screen is specified for the second Activity, it is further determined whether the package name information of the application to which the second Activity belongs is recorded in the first hash table and the second hash table, if no record is found, the identification information of the virtual screen specified for the second Activity and the package name information of the application to which the second Activity belongs are recorded in the first hash table and the second hash table, and if a record is found, no processing is performed on the first hash table and the second hash table.

In one embodiment, the control method according to the embodiment of the present disclosure further includes the following steps S3100 to S3400:

step S3100, in response to a trigger event for closing a first virtual screen, acquiring identification information of the first virtual screen.

The first virtual screen may be any one of virtual screens created and running in a 3D desktop environment of the head-mounted display device.

Step S3200, querying the second hash table according to the identification information of the first virtual screen, and obtaining package name information of the application corresponding to the identification information of the first virtual screen.

Step S3300, deleting at least one first hash data in the first hash table and a second hash data in the second hash table; the keyword of the first hash data is the packet name information of the application corresponding to the identification information of the first virtual screen, the hash value corresponding to the keyword is the identification information of the first virtual screen, the keyword of the second hash data is the identification information of the first virtual screen, and the hash value corresponding to the keyword is the packet name information of the application corresponding to the identification information of the first virtual screen.

Step S3400, sequentially killing the applications indicated by the packet name information of the application corresponding to the identification information of the first virtual screen.

According to the embodiment, the normal exit of the application running on the virtual screen can be realized when the virtual screen is closed.
