In one embodiment, the principle of the camera 300 acquiring the operation gesture is explained.

The actual imaging interface may become a virtual display screen, which in some embodiments may be a desktop, a wall, a dedicated projection screen, or other surface structure that presents a projected image, and the user's operation on the virtual display screen is identified by an image captured by a camera or location information transmitted by a controlled location sensing device.

Some exemplary operational acquisition modes are as follows:

(I) motion track

After the controller 200 controls the projection mechanism to project on the virtual display screen, the camera 300 captures an image of the finger of the user on the virtual display screen in real time and sends the image to the controller 200. The controller 200 recognizes the user's fingertip in the image by a fingertip tracking technique, and thus, the operation trajectory of the user on the virtual display screen can be obtained based on the movement trajectory of the fingertip.

In some embodiments, in the image acquired by the camera 300, if only a single finger is included, the operation trajectory of the user is determined based on the fingertip of the finger; if a plurality of fingers are included, the operation trajectory of the user is determined based on the fingertip of a specific finger, and the specific finger may be, for example, an index finger or the like, or the trajectories of a plurality of fingertips are determined.

(II) click operation

The camera 300 of the intelligent desk lamp is arranged above the finger of the user, when the user performs the finger pressing and clicking operation, the fingertip image of the user can be changed to a certain extent, and the controller 200 can identify whether the user performs the clicking operation according to the change of the fingertip image.

For example, when the position of the camera 300 is fixed, when the user performs the finger down-click operation, the distance between the fingertip and the camera 300 changes, and in the image acquired by the camera 300, the size of the fingertip pattern before the finger down-click is larger than the size of the fingertip pattern after the finger down-click, so that when the size of the fingertip pattern changes, it can be considered that the user performs the down-click operation.

For example, when some users click, the fingertips may bend downward, which may cause the image to have a deformed or incomplete fingertip pattern, and thus, when the fingertip pattern is deformed or displayed incompletely, the user may be considered to have performed a click operation.

It can be understood that when the fingertip image is just changed, the user can be considered to be in a fingertip pressing state; after the fingertip image is restored, the user can be considered to be in a fingertip lifting state, so that the fingertip image of the user changes once, and the user can be considered to have performed an effective click operation once.

(III) Single click operation

When the controller 200 confirms that the user is in a state of fingertip pressing, the position coordinates of the position Point1 of the state and the time stamp are recorded.

When it is confirmed that the user is in a state where the fingertip is lifted, the position coordinates and the time stamp of the position Point2 in the state are recorded.

If the distance between the position coordinates of position Point1 and position coordinates of position Point2 is smaller than a preset threshold, and the time difference between the timestamp of position Point1 and the timestamp of position Point2 is smaller than the preset threshold, it is considered that the user has performed a single-click operation at position Point1 (same as Point 2).

(IV) double click operation

When the controller 200 confirms that the user has performed the first valid click operation, the position coordinates and the time stamp of the position Point3 of the click operation are recorded.

When it is confirmed that the user has performed the second valid click operation, the position coordinates and the time stamp of the position Point4 of the click operation are recorded.

If the distance between the position coordinates of the position Point3 and the position coordinates of the position Point4 is smaller than a preset threshold, and the time difference between the timestamp of the position Point3 and the timestamp of the position Point4 is smaller than the preset threshold, it is considered that the clicking operation performed by the user at the position points Point3 and Point4 constitutes an effective double-click operation.

It is understood that the recognition principle of the multi-click operation is similar to that of the double-click operation, and the description thereof is omitted.

(V) Long-pressing operation

When the controller 200 confirms that the user is in a state of fingertip pressing, the position coordinates of the position Point5 of the state and the time stamp are recorded.

When it is confirmed that the user is in a state where the fingertip is lifted, the position coordinates and the time stamp of the position Point6 in the state are recorded.

If the distance between the position coordinates of position Point5 and position coordinates of position Point6 is smaller than a preset threshold, and the time difference between the timestamp of position Point5 and the timestamp of position Point6 is greater than the preset threshold, it is considered that the user has performed a long-press operation at position Point5 (same as Point 6).

(VI) sliding operation

When the controller 200 confirms that the user is in a state of fingertip pressing, the position coordinates of the position Point7 of the state and the time stamp are recorded.

When it is confirmed that the user is in a state where the fingertip is lifted, the position coordinates and the time stamp of the position Point8 in the state are recorded.

If the distance between the position coordinates of position Point7 and position coordinates of position Point8 is greater than a preset threshold, and the time difference between the time stamp of position Point7 and the time stamp of position Point8 is greater than a preset threshold, it is considered that the user has performed a sliding operation between position points 7 to 8.

It is understood that the sliding operation may be a lateral sliding, such as a leftward sliding or a rightward sliding, a longitudinal sliding, such as an upward sliding or a downward sliding, or an oblique sliding, such as an upward leftward sliding or a downward rightward sliding, etc.

In some embodiments, the sliding distance and the sliding direction (positive X-axis to the right and positive Y-axis to the up in the default position coordinate system) may be determined based on the position coordinates of the position Point7 and Point 8.

For example, the sliding distance may be calculated by the following formula:

where dis is the sliding distance, x7 and y7 are the position coordinates of position Point7, and x8 and y8 are the position coordinates of position Point 8.

When x7 is equal to x8 or the difference between x7 and x8 is smaller than a preset threshold, if y7> y8, the sliding direction is downward sliding; if y7< y8, the sliding direction is up.

When y7 is equal to y8 or the difference between y7 and y8 is smaller than a preset threshold, if x7> x8, the sliding direction is towards sitting; if x7< x8, the sliding direction is to the right.

When x7> x8, if y7> y8, the sliding direction is downward and leftward sliding; if y7< y8, the sliding direction is to slide left and up.

When x7< x8, if y7> y8, the sliding direction is rightward and downward sliding; if y7< y8, the sliding direction is to the right and upward.

In one embodiment, the user's operation on the virtual display screen may also be simulated by other peripheral devices. The peripheral devices are specifically such as an induction pen and the like.

In some embodiments, the pen point of the induction pen is provided with a position sensor, the position sensor transmits the position of the pen point to the controller 200 of the intelligent desk lamp in real time, and therefore the intelligent desk lamp obtains the operation track of the user on the virtual display screen through the position change condition transmitted by the controller 200.

In addition, the nib of the induction pen is provided with a pressing induction structure (for example, a pressure sensor and the like), when a user needs to perform a click operation, the user can touch the desktop by using the induction pen, so that the pressing induction structure acquires a pressing signal and sends the acquired pressing signal to the controller 200 of the intelligent desk lamp, and the controller 200 can determine the position where the user clicks based on the current position of the note and the pressing signal.

It is understood that the principle of other operations (such as double-click, long-press, etc.) performed by the user through the sensing pen is the same as that performed through the fingertip, and the detailed description thereof is omitted here.

For the convenience of understanding, in the following embodiments, the smart desk lamp is described by taking an example that the smart desk lamp includes a single controller 200, two projection mechanisms (the first imaging mechanism 110 and the second imaging mechanism 120), and a single camera 300, wherein the camera 300 only captures an operation gesture on the first virtual display screen VS1, the first virtual display screen VS1 projected by the first imaging mechanism 110 is formed on a desktop of a desk on which the smart desk lamp is disposed, and the second virtual display screen VS2 projected by the second imaging mechanism 120 is formed on a wall surface on which the desk leans.

In one embodiment, an application management method of an intelligent desk lamp is explained.

In some embodiments, a power-on key is arranged on the base of the intelligent desk lamp. The starting key can be a physical pressing type structure or a touch control structure, and when the starting key is in the physical pressing type structure, if a user presses the starting key, the starting key can be considered to be in an active state; when the power-on key is a touch structure, if a user's limb (e.g., a finger) is placed on the surface of the power-on key, the power-on key can be considered to be in an active state.

In some embodiments, the active state of the power-on key refers to a state in which the power-on key is pressed.

The traditional desk lamp is also provided with a start-up key, and after a user presses or touches the start-up key, a light source of the desk lamp is powered on to emit light, so that the lighting function is realized. Compare with traditional desk lamp, intelligent desk lamp still is provided with a plurality of virtual display screens, and after the start, except can realizing the illumination function, the virtual display screen can show predetermined projection picture to realize showing the function.

In some embodiments, the intelligent desk lamp can be provided with a start key and a projection key, when the intelligent desk lamp is started, the virtual display screen does not display a projection picture, so that the intelligent desk lamp can be used as a common desk lamp after being started, when a user needs to perform projection display, the user can press or touch the projection key to enable the virtual display screen to display the projection picture, the user presses or touches the projection key again, and the virtual display screen can close the display of the projection picture, so that the effect of saving energy is achieved.

In some embodiments, the function of the above-mentioned projection key may also be implemented by integrating it into a power-on key, for example, the power-on key is configured to be turned on or off by a user for a long time, and the user turns on or off the projection when clicking.

In some embodiments, after the user triggers the power-on key, the controller obtains a trigger signal of the power-on key, then generates a first start page and a second start page according to the trigger signal, then controls the desktop projection mechanism to project the first start page, controls the wall projection mechanism to project the second start page, and starts the camera, so that the operation of the user on the second start page and/or the first start page is monitored through the camera.

Referring to fig. 4, which is an interface schematic diagram of a second start page according to some embodiments, as shown in fig. 4, the second start page may not be provided with a control, and only shows some information that does not need to be focused by the user for a long time, such as weather information, time information, and the like. Of course, in some embodiments, the first launch page may also be provided with a small number of controls, for example, "weather sunny" in fig. 4 may be an interface control, and the user may enter the weather detail interface by clicking on the interface control.

Referring to fig. 5, which is an interface schematic diagram of a first start-up page according to some embodiments, the first start-up page may include an education interface, as shown in fig. 5, the education interface may be provided with a plurality of controls, such as "online teaching system", "teaching channel", "exercise practice", "test simulation", and "homework correction", each of the controls is a display position, and after a user clicks one of the controls, the user may enter the interface corresponding to the control. The first starting page can be provided with a two-screen control D, and the control D is configured to call up a control interface for operating the wall surface projection interface on the current interface in response to triggering.

In some embodiments, it may be inconvenient for the user to directly operate the control on the second launch page, and the user may click the D control on the first launch page shown in fig. 5, thereby bringing up the control interface of the second launch page on the first virtual display screen, and operating on the second launch page on the control interface.

It should be noted that, referring to fig. 5, in some embodiments, for the first virtual display VS1, the interface lower side of the Launcher interface includes 4 control keys, which are a return key, a home key, a progress key, and a minimize key. The return key is used for returning to a previous page, the home page key is used for directly returning to a corresponding Launcher interface, the process key is used for displaying all current processes to conduct process management, and the minimize key is used for minimizing the application running in the current foreground.

In one embodiment, the screen display control of the second virtual display screen VS2 is explained.

Referring to fig. 5, a two-screen control D is disposed on a display page of the first virtual display screen VS1, and when a user clicks the two-screen control D, the first virtual display screen VS1 displays a display control interface of the second virtual display screen VS2 above an original interface.

Fig. 6 is a schematic diagram of a display control interface D0 corresponding to the two-screen control D, and as shown in fig. 6, the display control interface D0 includes a display area D1, a return-to-one-screen control D2, a close-two-screen control D3, a touch area D4, and an exit control D5.

The display area D1 is used to display the currently running process of the second virtual display screen VS 2.

The return-to-one screen control D2 is used to switch the content displayed on the second virtual display screen VS2 to the first virtual display screen VS1 for display. For example, for a process, if the currently displayed content of the process is displayed on the second virtual display VS2, and if the user clicks the return-to-one-screen control D2, the process switches to the first virtual display VS1 for display, and at this time, the second virtual display VS2 may display a Launcher interface or a time interface.

The close two-screen control D3 is used to switch the content displayed on the second virtual screen VS2 to the first virtual screen VS1 for display, while the second virtual screen VS2 is turned off. For example, for a certain process, if the currently displayed content of the process is displayed on the second virtual display screen VS2, if the user clicks the off-two-screen control D3, the process switches to the first virtual display screen VS1 for display, at this time, the second virtual display screen VS2 switches to the off-screen state, that is, the second virtual display screen VS2 does not display the content.

Touchpad D4 is used to control the operation of second virtual display screen VS2 (in a similar manner to a notebook touchpad). According to the operation of the user in the touch area D4 acquired by the camera, the mapping relation between the position of the operation of the user in the touch area D4 and the preset position, the operation of the user is mapped to the operation of the corresponding position of the VS2 of the second virtual display screen, and then the control for executing the operation is determined according to the position of the VS2 control of the second virtual display screen. For example, the user can manipulate a screen pointer on the second virtual display screen VS2 through the touch area D4, so as to perform corresponding operations.

The exit control D5 is used to collapse the display control interface D0. For example, the user may collapse the display control interface D0 by clicking the exit control D5, and at this time, the icon of the two-screen control D is displayed on the first virtual display screen VS 1.

In one embodiment, the process control management of the first virtual display VS1 and the second virtual display VS2 is explained.

In some embodiments, an application on the intelligent desk lamp may generate a process of the application on the intelligent desk lamp after being started, and thus, managing the application may include managing the process of the application.

In some embodiments, the applications on the smart desk lamp include three types, the first type is an application that is only exposed on the first virtual display screen VS1, the applications may include interactive applications that the developer of the smart desk lamp self-develops, the second type is an application that is only exposed on the second virtual display screen VS2, the applications may include presentation-type applications of a third party, the third type is an application that is both exposed on the first virtual display screen VS1 and the second virtual display screen VS2, the applications may include comprehensive applications that the developer of the smart desk lamp self-develops, the first type and the second type of applications may be referred to as single-screen applications, and the third type of applications may be referred to as double-screen applications. The interactive application may refer to an application that requires a user to perform a large number of operations, such as a game application, and the user needs to perform real-time control; the presentation application may refer to an application that does not require user operation, or requires only a small amount of user operation, such as a weather application, that does not require user operation, or that requires only input of a geographic location; the comprehensive application may refer to an application that requires a user to operate in some scenarios and does not require the user to operate in some scenarios, such as a notepad application, where the user needs to interact with the application when inputting an event, and after inputting the event, the application only needs to display the event input by the user.

In some embodiments, in order to enable the smart desk lamp to identify which virtual display screen an application needs to be displayed on, some applications may carry a screen identifier in an installation package, where the screen identifier may be a screen parameter, and if the parameter takes the value of VS1, the screen identifier may be a first identifier indicating that the application is of a type that needs to be displayed on the first virtual display screen VS1, a process generated after the application is started may be referred to as a first type of process, if the parameter takes the value of VS2, the screen identifier may be a second identifier indicating that the application is of a type that needs to be displayed on the second virtual display screen VS2, a process generated after the application is started may be referred to as a second type of process, and if the parameter takes the value of (VS1, VS2), the screen identifier may be a third identifier indicating that the application is of a type that needs to be displayed on both the first virtual display screen VS1 and the second virtual display screen VS2, the processes generated by the application after startup may be referred to as processes of a third type. It should be noted that, for an application with a screen parameter value of 3, at a certain time, the application may display interfaces on two display screens, or may display an interface on only one display screen. After the applications are installed on the intelligent desk lamp, the screen identification can be stored in the installation information of the applications. In some embodiments, some applications may not carry screen identification in their installation package, and the smart desk lamp may default that the application needs to be displayed on the first virtual display VS1 or the second virtual display VS 2. After the applications are installed on the intelligent desk lamp, the intelligent desk lamp can add screen identification in installation information of the applications.

In some embodiments, the process management timing diagram of the installed application on the intelligent desk lamp can be seen in fig. 7, and in fig. 7, the application management stack, the application process management module, and the desktop management module can be software modules executed on a controller of the intelligent desk lamp.

In some embodiments, after the smart desk lamp is turned on, the controller of the smart desk lamp may create three application management stacks for storing an application displayed only on the first virtual display VS1, an application displayed only on the second virtual display VS2, and screen usage information of an application provided with a display screen on each of the first virtual display VS1 and the second virtual display VS 2. The screen use information can be the same as the screen identification in the installation information of the application program when the application is started, and if a user switches the display screen displayed by the application program in the later period, the screen use information can change along with the operation of the user and is different from the screen identification in the installation information of the application program.

In some embodiments, after the intelligent desk lamp is turned on, the controller of the intelligent desk lamp may also not create the application management stack first, and create the first application management stack after the user starts an application displayed only on the first virtual display screen VS 1; after the user starts an application displayed only on the second virtual display VS2, a second application management stack is created; after the user starts an application having a display screen on each of the first virtual display VS1 and the second virtual display VS2, a third application management stack is created.

Taking the example that the intelligent desk lamp automatically creates three application management stacks after being started, in some embodiments, a user may click one application program from a first start page or a second start page to generate an application start instruction of the application program.

In some embodiments, the controller of the intelligent desk lamp responds to the application starting instruction to start the application program, and the application program generates at least one starting interface after starting. If the application program is a double-screen application, two starting interfaces are generated, the application program can respectively set screen identifiers for the two starting interfaces, so that the controller can read the screen identifiers corresponding to the starting interfaces and project the two starting interfaces to corresponding virtual display screens according to the screen identifiers; and if the application program is single-screen application, generating a starting interface, wherein the application program can set a screen identifier which is the same as the screen identifier of the application program for the starting interface, so that the controller can read the screen identifier corresponding to the starting interface and project the starting interface onto the corresponding virtual display screen according to the interface screen identifier.

In some embodiments, the controller of the intelligent desk lamp responds to the application starting instruction, and obtains the screen identifier of the application program from the installation information of the application program. If the value of the screen identifier is VS1, adding the screen use information of the application program into the first application management stack; if the value of the screen identifier is VS2, adding the screen use information of the application program into a second application management stack; and if the screen identifier takes the value of (VS1, VS2), adding the screen use information of the application program into the third application management stack.

In some implementations, after a user starts an application, the user can return to the display interface where the icon of the application is located, when the user clicks the application again on the display interface, an application entering instruction is input into the intelligent desk lamp, and the intelligent desk lamp redisplays the interface of the application according to the application entering instruction.

In some embodiments, a user may continue to launch other applications after launching one application. After each application is started, the screen use information of the application is stored in the corresponding application management stack. In an application management stack, the screen use information of each application is sorted according to the opening sequence of a user, the application opened by the user firstly is positioned at the bottom of the stack, the application opened by the user finally is positioned at the top of the stack, and the screen use information sequence of each application in the application management stack is automatically adjusted along with the operation of the user as the user switches the applications back and forth.

In some embodiments, if a user opens more applications, the memory resource consumption of the intelligent desk lamp will be large, and the user may perform process management on the intelligent desk lamp, for example, close some applications, to release the memory resource occupied by the applications.

In some embodiments, the user may click on a process control on the first virtual display VS1 to manage the launched application.

In some embodiments, the user may also slide upward from the bottom of the first virtual display VS1 to trigger a process control to manage the opened application.

In some embodiments, after the user clicks the process control, the application process management module responds to the trigger signal of the process control to control the intelligent desk lamp to display a process management page for the user to perform application management.

In some embodiments, the application process management module, in response to the trigger signal of the process control, may read screen usage information of a currently-started application stored in each application management stack, and determine a process currently running in the memory of the intelligent desk lamp. After the screen use information of the currently opened application is read, the screen use information can be processed, and therefore a process management interface is generated.

To facilitate the user's understanding of the applications currently running on the first virtual display VS1 and the applications running on the second virtual display VS2, the application windows of all open applications may be presented on a regular basis.

In some embodiments, one way in which application processes are presented on a regular basis may be to alternate the ordering of the presentation by application processes that differ in screen usage information.

In some embodiments, the application process management module may calculate, according to the screen usage information of the started applications, the number of applications corresponding to each application management stack, to obtain that the number of the one-screen applications is M, the number of the two-screen applications is N, and the number of the one/two-screen applications is Q, where the one-screen application refers to an application whose current display screen is the first virtual display screen VS1, the two-screen application refers to an application whose current display screen is the second virtual display screen VS2, and the one/two-screen application refers to an application whose current display screen is the first virtual display screen VS1 and the second virtual display screen VS 2.

In some embodiments, the method for alternately ordering different application processes may be: the priority of the first class process, the priority of the second class process and the priority of the third class process are the same, the first class process, the second class process and the third class process are alternately ordered, and then the processes of the rest classes are alternately ordered.

According to the sorting mode, if the running processes only have the first class processes and the second class processes, when M is larger than or equal to N and N is larger than zero, the first N first class processes and the N second class processes are alternately displayed on the first 2N sequence bits on the process management page, and the remaining sequences of the remaining M-N first class processes after the first 2N sequence bits are sequentially arranged. And when M is smaller than N, alternately displaying the first M first-class processes and the M second-class processes on the first 2M sequence bits on the process management page, wherein the rest sequences of the rest N-M second-class processes after the first 2M sequence bits are sequentially arranged.

According to the sorting mode, if the running processes comprise a first class process, a second class process and a third class process, when M is larger than or equal to N, N is larger than or equal to Q, and Q is larger than zero, the first Q first class processes, the first Q second class processes and the Q third class processes are alternately displayed on the first 3Q sequence bits on the process management page, the N-Q first class processes and the N-Q second class processes are alternately displayed on the 2(N-Q) sequence bits after the first 3Q sequence bits on the process management page, and the rest M-N first class processes are displayed on the subsequent sequence bits. And when M is less than N, M and is greater than Q, alternately displaying the first Q first-class processes, the first Q second-class processes and the Q third-class processes on the first 3Q sequence bits on the process management page, alternately displaying the M-Q first-class processes and the M-Q second-class processes on the 2(M-Q) sequence bits after the first 3Q sequence bits on the process management page, and displaying the rest N-M second-class processes on the subsequent sequence bits.

In some embodiments, the method for alternately ordering and presenting different application processes may be: the priority of the first class process and the priority of the second class process are the same and are greater than the priority of the third class process, the first class process and the second class process are alternately ordered, and then the rest processes and the third class process are alternately ordered, or the second class process and the first class process are alternately ordered, and then the rest processes and the third class process are alternately ordered.

According to the sorting mode, when M is smaller than N, several specific sorting modes are as follows:

if M is smaller than N and the sum of M and Q is smaller than N, the application process management module may alternately sort the application processes of the two-screen application and the application processes of the one-screen application, and then alternately sort the remaining application processes of the two-screen application and the application processes of the one/two-screen application. Because the sum of M and Q is less than N, a part of application processes of the two-screen application cannot be alternately sequenced with application processes with different screen use information, and the part of application processes of the two-screen application can be directly displayed in an overlapping mode to finally obtain a group of overlapped processes. Ordering effects referring to fig. 8, in fig. 8, the ordering of application processes for the same screen usage information is consistent with the ordering of screen usage information within the respective application management stacks.

If M is smaller than N and the sum of M and Q is equal to N, the application process management module can alternately sort the application processes of the two-screen application and the application processes of the one-screen application, and then alternately sort the remaining application processes of the two-screen application and the application processes of the one/two-screen application, and finally obtain a group of superposed windows. The sorting effect can be seen in fig. 9, the sorting of the application processes with the same screen usage information is consistent according to the sorting of the screen usage information in the respective application management stacks.

If M is smaller than N and the sum of M and Q is larger than N, the application process management module may alternately sort the application processes of the two-screen application and the application processes of the one-screen application, and then alternately sort the remaining application processes of the two-screen application and the application processes of the one/two-screen application. Because the sum of M and Q is larger than N, a part of application processes of the one-screen/two-screen application cannot be alternately sequenced with application processes with different screen use information, and the part of application processes of the one-screen/two-screen application can be directly displayed in an overlapping mode to finally obtain a group of overlapped windows. Ordering effects see fig. 10, where the ordering of application processes for the same screen usage information is consistent with the ordering of screen usage information within the respective application management stacks in fig. 10.

If M is greater than N, the processes of the started applications can be sorted according to the condition that the sum of N and Q is less than M, N and the sum of Q is equal to M, N and the sum of Q is greater than M, and the sorting method can be similar to the sorting method when M is less than N, and is not described herein again.

In some embodiments, after the controller sorts the first class process, the second class process, and the third class process according to the above alternate sorting rule, the process management page may be generated according to the sorted processes.

In some embodiments, in the process management page, the multiple processes are displayed in a vertically overlapped manner according to the above alternate sorting, the process sorted in the front may form a shield on a preset area of the process arranged in the rear, the preset area may be a lower area, and the partially shielded overlapped display mode may display more processes in a smaller area than the tiled display mode of all the processes. In some embodiments, the manner in which an application process is presented on a regular basis may also be a separate presentation of application processes that differ in screen usage information. After the application process management module obtains the screen use information of the opened application from each application management stack, the application process management module can display the application process of the one-screen application in a superposition mode, display the application process of the two-screen application in a superposition mode, display the application process of the one-screen application/the two-screen application in a superposition mode, and obtain three groups of processes displayed in a superposition mode. The sorting effect can be seen in fig. 11, as shown in fig. 11, each class of processes can be arranged separately, and processes in different classes can be separated by a preset distance, which is convenient for a user to distinguish and difference.

In fig. 11, the ordering of application processes for the same screen usage information is consistent with the ordering of screen usage information within the respective application management stacks.

In some embodiments, after obtaining the sequence of all application processes with applications started, the application management process may generate a process management interface provided with a screen identifier VS1 according to the beat sequence, and then send the application management process interface to the desktop management module according to the screen identifier VS1, so that the desktop management module may display the process management interface on the first virtual display screen VS 1.

For example, the process management interface can be seen in fig. 12, and the user can manage the currently running process through the process management page, for example, close, switch the display screen, and so on.

As shown in fig. 12, a plurality of currently running processes are displayed in a stacked manner, and a user can select a process to be managed by scrolling the processes up and down. For example, the currently managed process is process one, and by scrolling down, the currently managed process can be switched to process two.

In some embodiments, after the currently managed process is switched, if the user clicks and selects the currently managed process, the content of the currently managed process is directly displayed on the corresponding virtual display screen.

In addition, a label A is arranged in a corresponding area of different processes, and the label A is used for identifying the virtual display screen on which the process is currently displayed. The label a may be determined according to the screen identifier, and may display "one screen" if the screen identifier is VS1, may display "two screens" if the screen identifier is VS2, and may display "one screen + two screens" if the screen identifier is (VS1, VS 2). After receiving an input instruction for process management, acquiring an operating process and a position presented by the process, and displaying in a label sub-control of a process control controlled by the position presented before receiving the instruction according to an application corresponding to the process (a first virtual display VS1 or a second virtual display VS2), wherein the content displayed by the label sub-control at the position presented before receiving the instruction is different for the application corresponding to the process. For example, tag a1 corresponding to process one in fig. 12 is "one screen", which means that process one is displayed on the first virtual screen VS 1; label a2 corresponding to process two is "two screens", i.e. it means that process two is displayed on second virtual screen VS 2; label a3 corresponding to process three is "one screen + two screen", that is, it indicates that process three is simultaneously displayed on the first virtual display VS1 and the second virtual display VS 2. At this time, if the user clicks to select the first process, directly displaying the content corresponding to the first process on the first virtual display screen VS 1; if the user clicks the selected process two, directly displaying the content corresponding to the process two on a second virtual display screen VS 2; if the user clicks and selects the process three, the content corresponding to the process three is directly displayed on the first virtual display screen VS1 and the second virtual display screen VS 2.

It is to be understood that the multiple processes currently running may also be displayed in other forms, for example, in a form of multiple small windows, and the display form of the multiple processes is not limited in this application.

In addition, the expression form of the tag content is not limited in the application, the tag content can be any combination of numbers, letters and characters, and a user can clearly and intuitively know which virtual display screen the process is displayed on according to the tag content. For example, the tag content "one screen" in fig. 12 may also be "1", "two screens" may also be "2", and the like.

In some embodiments, referring to fig. 12, after the user opens the process management page, in addition to seeing which virtual display screen the process is displayed on, the user can also perform process shutdown management on the currently running process. In some embodiments, the user may close the running process through process close control B.

For example, the user may close process one by clicking on process close control B1 corresponding to process one, close process two by clicking on process close control B2 corresponding to process two, and close process three by clicking on process close control B3 corresponding to process three. Thus, the user can shut down the process needing to be shut down in a targeted manner.

In some embodiments, referring to fig. 12, the process management page is further provided with a one-touch closing control B0, and when the number of processes that need to be closed currently is large, the user can close all currently running processes by clicking the one-touch closing control B0 without clicking the process closing controls corresponding to the processes one by one, so that the process closing efficiency can be improved.

After the user completes the process closing operation, the page before the process management can be returned by clicking the return key. In some embodiments, after completing the process shutdown operation, if the user clicks on a blank in the process management interface, an educational interface in the Launcher interface is returned.

In some embodiments, after opening the process management page, the user may perform process closing management on the currently running process, and may also switch the virtual display screen corresponding to the currently running process. In some embodiments, the user may perform a display screen switch on the process by applying the display screen switch control C.

In some embodiments, application display screen toggle control C can include control C1 and control C2. The triggering mode of the control C1 may be that a user operation of sliding leftward is received in the display area of the top-most process, an instruction for switching the application display screen may be generated after the triggering, and the top-most process may be switched to the second virtual display screen VS2 in response to the instruction; the control C2 may be triggered in such a way that a user operation of sliding to the right is received in the display area of the topmost process, and the topmost process may be switched to the first virtual display CS1 in response to the trigger. As shown in FIG. 12, control C1 and control C2 can be simultaneously exposed on the process management page. As shown in FIG. 13, control C1 may also be displayed only when the top-most application is a one-screen process. As shown in FIG. 14, control C2 may also be displayed only when the top-most application is a two-screen process.

In some embodiments, when the currently managed process is process one, the tag a1 corresponding to process one is "one screen", that is, process one is displayed on the first virtual display screen VS1 before receiving the process management instruction, at this time, the user may perform a left-sliding operation corresponding to the control C1 to switch process one to the second virtual display screen VS2 for display, at this time, the first virtual display screen VS1 no longer displays the content of process one, that is, display process one by switching between different screens.

In some embodiments, when the currently managed process is process one, the user may perform a right-slide operation corresponding to control C2, and the process one is still shown on one screen.

In some embodiments, when the currently managed process is process two, the tag a2 corresponding to process two is "two screens", that is, process two is displayed on the second virtual display screen VS2 before receiving the process management instruction, at this time, the user may perform a right-sliding operation corresponding to the control C2 to switch process two to the first virtual display screen VS1 for display, at this time, the second virtual display screen VS2 no longer displays the content of process two, that is, the process two is displayed by switching between different screens.

In some embodiments, when the currently managed process is process two, the user may perform a left-sliding operation corresponding to the control C1, and process two is still displayed on the two screens.

In some embodiments, when the currently managed process is process three, the label a3 corresponding to process three is "one screen + two screens", that is, at this time, process two is displayed on the first virtual display screen VS1 and the second virtual display screen VS2 before receiving the process management instruction, at this time, the user may perform a left-sliding operation corresponding to the control C1 to switch process three to the second virtual display screen VS2 for display, at this time, the first virtual display screen VS1 no longer displays the content of process three, that is, switch process three from a two-screen display to a single-screen (the second virtual display screen VS2) for display. At this time, the first virtual display screen VS1 may display a Launcher interface, for example, an educational interface or the like.

In some embodiments, the user may also perform a right-sliding operation corresponding to the control C2 to switch the process three to the first virtual display screen VS1 for displaying, at this time, the second virtual display screen VS2 no longer displays the content of the process three, that is, the process three is switched from the dual-screen display to the single-screen display (the first virtual display screen VS 1). At this time, the second virtual display screen VS2 may display a Launcher interface or a time interface.

In some embodiments, the controls C1 and C2 are conditionally hidden/displayed, i.e., the controls C1 and C2 are not always in a displayed state.

In some embodiments, the control C1 is not displayed until the currently managed process is currently displayed on the first virtual display VS1 and can be switched to the second virtual display VS2 for display (e.g., process one in fig. 12), and the control C2 is hidden.

When the currently managed process is currently displayed on the second virtual display VS2 and can be switched to the first virtual display VS1 for display (for example, process two in fig. 12), the control C2 is displayed, and at this time, the control C1 is hidden.

When the currently managed process is currently displayed on the first virtual display VS1 and the second virtual display VS2, and can be switched to the first virtual display VS1 or the second virtual display VS2 for display separately (for example, process three in fig. 12), the control C1 and the control C2 are simultaneously displayed.

When the currently managed process is currently displayed on the first virtual display VS1 and the second virtual display VS2 and cannot be switched to the first virtual display VS1 or the second virtual display VS2 for display alone (for example, process three in fig. 12), the control C1 and the control C2 are hidden.

Therefore, by setting the controls C1 and C2 as conditional hiding/displaying, it is possible to avoid causing interference to the user when the user switches the display.

In some embodiments, the user may also set controls C1 and C2 to be always displayed or always hidden by setting them to be always hidden.

In one embodiment, a plurality of intelligent table lamps are connected through a network to form a communication system, a plurality of users corresponding to the plurality of intelligent table lamps can perform information interaction through the communication system, and the plurality of users can be users with different identity types. For example, the plurality of users may include a first number of first identity users and a second number of second identity users, and so on.

As can be seen from the above embodiments, in the embodiments of the present application, the application process running on the first display picture, the application process running on the second display picture, and the application processes running on the first display picture and the second display picture are alternately displayed in an overlapping manner or displayed in an overlapping manner according to the display positions on the process management interface, so that the application process is regularly displayed, which is beneficial to a user to check the processes on the display pictures, and the user can conveniently perform process management, thereby improving the user experience.
