In some embodiments, the desk lamp may be provided with a projection mechanism, capable of being connected with a display device, to realize a projection function of a projector, and may be referred to as an intelligent desk lamp.

However, in the conventional projection technology, the content of the display device is directly projected, if the content displayed by the display device is superimposed content, the projected image is also displayed by the superimposed content, for example, in a video chat scene, the chat window is usually superimposed over the original interface, which can cause shielding to the content of the original interface, and affect the viewing experience of the user.

In order to solve the technical problem, the embodiment of the application enables the desk lamp to be an intelligent display device by arranging the plurality of projection mechanisms on the desk lamp, a plurality of pictures can be obtained through projection, and then a plurality of interfaces of an application program are displayed on the projected pictures in a separated mode, so that the interfaces are not blocked.

Fig. 1 is a schematic structural diagram of an intelligent desk lamp according to some embodiments of the present application, as shown in fig. 1, the intelligent desk lamp includes: at least two imaging mechanisms, a controller 200, and a camera 300. The imaging mechanism may be a projection mechanism, and the controller 200 is connected to at least two projection mechanisms and the camera 300, respectively, so that the controller 200 may control the working states of the at least two projection mechanisms and acquire contents photographed by the camera 300.

In some embodiments, the intelligent desk lamp further comprises a base, a support and an illumination bulb, wherein the illumination lamp, the projection mechanism and the camera can be arranged on the support, the support can be arranged on the base, and the controller 200 can be arranged inside the base.

In some embodiments, the controller 200 in the intelligent desk lamp has a network communication function, so that the current intelligent desk lamp can communicate with other intelligent desk lamps, intelligent terminals (such as mobile phones) or servers (such as network platforms), thereby obtaining projection contents.

In some embodiments, the controller 200 in the intelligent desk lamp may also be installed with an operating system, so that projection can be performed without connecting with a display device, and of course, the intelligent desk lamp with the operating system may also have a network communication function, so that communication with a server or the like can be performed, so as to implement some network functions, such as upgrading the operating system, installing an application program, interacting with other intelligent desk lamps, and the like. Referring to fig. 1, at least two projection mechanisms include at least a first imaging mechanism 110 and a second imaging mechanism 120, where the first imaging mechanism 110 may also be referred to as a desktop projection mechanism for projecting to form a first virtual display screen VS1; the second imaging mechanism 120 may also be referred to as a wall projection mechanism, and is configured to project and form a second virtual display screen VS2, where the first virtual display screen VS1 and the second virtual display screen VS2 are formed at different positions.

For example, fig. 2 is a schematic diagram illustrating a virtual display forming position in some embodiments of the present application, as shown in fig. 2, a first virtual display VS1 formed by projection of the first imaging mechanism 110 may be formed on a desktop of a desk provided with the smart desk lamp, the desktop may be a horizontal plane, and an interface on the first virtual display VS1 may be referred to as a first display screen; the second virtual display screen VS2 projected by the second imaging mechanism 120 may be formed on a wall surface on which the desk rests, and the wall surface may be a vertical plane, and an interface on the second virtual display screen VS2 may be referred to as a second display screen. It will be appreciated that in practical applications, the forming position of the virtual display screen may be adjusted according to practical needs, the desktop may be a substantially horizontal plane, and the wall surface may be a substantially vertical plane.

It can be understood that the specific display content of the first virtual display screen VS1 may be different from the specific display content of the second virtual display screen VS2, so that the two virtual display screens cooperate with each other to achieve the purpose of comprehensively displaying the content with large capacity and high complexity.

After the at least two projection mechanisms respectively project to form at least two virtual display screens, the camera 300 is configured to collect an operation gesture on at least one virtual display screen, and send the operation gesture to the controller 200, where the operation gesture may specifically be operation click information of a user on display content on the virtual display screen.

For example, the camera 300 may collect only the operation gesture on the first virtual display screen VS1, may collect only the operation gesture on the second virtual display screen VS2, or may collect the operation gestures on the first virtual display screen VS1 and the second virtual display screen VS2 simultaneously.

In addition, based on the number of virtual display screens required to acquire operation gestures, the number of cameras 300 may be set to be plural, that is, a single camera acquires operation gestures of a single virtual display screen.

For example, the controller 200 may adjust only the projected content of the first imaging mechanism 110 on the first virtual display screen VS1 based on the operation gesture, may adjust only the projected content of the second imaging mechanism 120 on the second virtual display screen VS2 based on the operation gesture, and may adjust both the projected content of the first imaging mechanism 110 on the first virtual display screen VS1 and the projected content of the second imaging mechanism 120 on the second virtual display screen VS2 based on the operation gesture.

It will be appreciated that the two projection mechanisms are only one exemplary illustration of performing multi-screen projection on the intelligent desk lamp in the present application, and the at least two projection mechanisms may also be other numbers of projection mechanisms, for example, 3 or more than 3, etc., where the number of projection mechanisms of the intelligent desk lamp is not specifically limited in the present application. In addition, for convenience of explanation, each embodiment of the present application uses two projection mechanisms as an example, and the technical solution of the present application will be explained.

In some embodiments, the number of the controllers 200 may be plural, specifically, may be the same as the number of the projection mechanisms, so that a single controller may be configured to control the projection content of a single projection mechanism, and communication connections exist between the respective controllers.

For example, for a case where at least two projection mechanisms include at least a first imaging mechanism 110 and a second imaging mechanism 120, the controller 200 may specifically include a first controller that controls the projected content of the first imaging mechanism 110 and a second controller that controls the projected content of the second imaging mechanism 120, where the first controller and the second controller have a communication connection.

In some embodiments, the plurality of controllers may be centrally located, i.e., the plurality of controllers are located at the same designated location in the intelligent desk lamp; the controllers may be separately provided, that is, the controllers may be provided corresponding to the corresponding projection mechanisms, and the present application does not limit the positions of the plurality of controllers.

In one embodiment, the principle of the camera 300 capturing operation gestures is explained.

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

Exemplary some of the operation acquisitions are as follows:

motion trail

After the controller 200 controls the projection mechanism to project on the virtual display screen, the camera 300 captures an image of the user's finger on the virtual display screen in real time and transmits the image to the controller 200. The controller 200 recognizes the user's fingertip in the image through the fingertip tracking technology, so that the operation track of the user on the virtual display screen can be obtained based on the movement track of the fingertip.

In some embodiments, in the image acquired by the camera 300, if only a single finger is included, determining an operation track of the user based on the fingertip of the finger; if a plurality of fingers are included, the operation locus of the user is determined based on the finger tips of the specific fingers, which may be, for example, index fingers or the like, or the locus of the plurality of finger tips is 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 operation of pressing and clicking the finger, the fingertip image of the user can change 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, in the case where the position of the camera 300 is fixed, when the user performs the finger-down clicking operation, the distance between the fingertip and the camera 300 changes, and in the image obtained by the camera 300, the fingertip pattern size before the finger-down clicking is larger than the fingertip pattern size after the finger-down clicking, so that the user can be considered to perform the finger-down clicking operation when the fingertip pattern size changes.

For example, when some users click, there is a case that the fingertip is bent downward, and the fingertip pattern in the image is deformed or incomplete, so that when the fingertip pattern is deformed or incomplete in display, the user can be considered to perform the pressing click operation.

It can be appreciated that when the fingertip image has just changed, the user can be considered to be in a fingertip press-down state; after the fingertip image is restored, the user can be considered to be in a fingertip lifting state, and thus, the fingertip image of the user changes once, and the user can be considered to perform an effective clicking operation once.

(III) Single click operation

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

When confirming that the user is in a state of lifting the fingertip, the position coordinates of the position Point2 of the state and a time stamp are recorded.

If the distance between the position coordinates of the position Point1 and the position coordinates of the position Point2 is smaller than the preset threshold value, and the time difference between the time stamp of the position Point1 and the time stamp of the position Point2 is smaller than the preset threshold value, the user is considered to perform the clicking operation on the position Point1 (same as the position Point 2).

(IV) double-click operation

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

When the user is confirmed to perform the second effective clicking operation, the position coordinates of the position Point4 of the clicking operation and a time stamp are recorded.

If the distance between the position coordinates of the position Point3 and the position coordinates of the position Point4 is smaller than the preset threshold value and the time difference between the time stamp of the position Point3 and the time stamp of the position Point4 is smaller than the preset threshold value, the clicking operation performed by the user at the position points Point3 and Point4 is considered to form an effective double-click operation.

It will be appreciated that the principle of recognition of the multiple click operation is similar to that of the double click operation, and will not be described in detail herein.

(fifth) Long press operation

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

When confirming that the user is in a state of lifting the fingertip, the position coordinates of the position Point6 of the state and a time stamp are recorded.

If the distance between the position coordinates of the position Point5 and the position coordinates of the position Point6 is smaller than the preset threshold value, and the time difference between the time stamp of the position Point5 and the time stamp of the position Point6 is larger than the preset threshold value, the user is considered to perform long-press operation on the position Point5 (same as the position Point 6).

Sixth sliding operation

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

When confirming that the user is in a state of lifting the fingertip, the position coordinates of the position Point8 of the state and a time stamp are recorded.

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

It will be appreciated that the sliding operation may be a sideways sliding, such as a left or right sliding, a longitudinal sliding, such as an upward or downward sliding, or an oblique sliding, such as an upward or downward and left sliding, etc.

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

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

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

When x7=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 upward.

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

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

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

In one embodiment, the operation of the user on the virtual display screen can be simulated through other peripheral devices. The peripheral device is specifically such as a sensing pen.

In some embodiments, the pen tip of the sensing pen is provided with a position sensor, and the position sensor sends the position of the pen tip to the controller 200 of the intelligent desk lamp in real time, so that the intelligent desk lamp obtains the operation track of the user on the virtual display screen through the position change condition sent by the controller 200.

In addition, the nib of the sensing pen is provided with a pressing sensing structure (such as a pressure sensor, etc.), when a user needs to perform clicking operation, the user can touch the desktop by using the sensing pen, so that the pressing sensing structure obtains a pressing signal, and the obtained pressing signal is sent to the controller 200 of the intelligent desk lamp, and the controller 200 can determine the clicking position of the user based on the current position of the note and the pressing signal.

It will be appreciated that the principle of other operations (e.g. double click, long press, etc.) performed by the user through the sensing pen is the same as that performed by the fingertip, and will not be described in detail here.

For ease of understanding, in the following embodiments, the smart desk lamp includes a single controller 200, two projection mechanisms (a first imaging mechanism 110 and a second imaging mechanism 120), and a single camera 300, where the camera 300 only collects an operation gesture on a first virtual display screen VS1, the first virtual display screen VS1 formed by projection of the first imaging mechanism 110 is formed on a desk top of the desk on which the smart desk lamp is disposed, and the second virtual display screen VS2 formed by projection of the second imaging mechanism 120 is formed on a wall surface on which the desk is disposed.

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

In some embodiments, a power-on key is provided on the base of the intelligent desk lamp. The power-on key can be in a physical pressing structure or a touch structure, and when the power-on key is in the physical pressing structure, if a user presses the power-on key, the power-on key can be considered to be in an active state; when the power-on key is in a touch structure, if a limb part (such as a finger) of a user 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 power-on key being in an active state refers to a state in which the power-on key is pressed.

The traditional desk lamp is also generally provided with a start key, and after a user presses or touches the start key, a light source of the desk lamp can be electrified to emit light, so that the lighting function is realized. Compared with the traditional desk lamp, the intelligent desk lamp is further provided with a plurality of virtual display screens, after the intelligent desk lamp is started, the intelligent desk lamp can realize an illumination function, and the virtual display screens can display preset projection pictures, so that a display function is realized.

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

In some embodiments, the functions of the projection key may also be integrated into a power-on key, for example, the power-on key is configured to be turned on or off when the user presses the key for a long time, and the projection is turned on or off when the user clicks the key.

In some embodiments, after a user triggers a start key, the controller obtains a trigger signal of the start 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, 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 displays some information such as weather information, time information, and the like, which do not need to be focused by a user for a long time. Of course, in some embodiments, the first launch page may also set a small number of controls, e.g., the "weather fine" in fig. 4 may be an interface control that the user clicks on to access the weather details interface.

Referring to fig. 5, an interface schematic diagram of a first start page according to some embodiments may include an educational interface, as shown in fig. 5, where the educational interface may be provided with a plurality of controls, such as "online teaching system", "teaching channel", "problem exercise", "simulation examination", "job correction", each of which is a display position, and after a user clicks a control, the user may enter an interface corresponding to the control. A two-screen control D may be disposed on the first actuation page, the control D being configured to call up a control interface for operating the wall projection interface on the current interface in response to a trigger.

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 on the D control in the first launch page shown in fig. 5, thereby calling up a control interface of the second launch page on the first virtual display screen, and operating 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, 4 control keys are included below the interface of the host interface, which are respectively a return key, a home key, a process key, and a minimize key. The method comprises the steps of setting a process key, a minimize key and a main key, wherein the return key is used for returning to a previous page, the main 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 set on the display page of the first virtual display screen VS1, and when the 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 the original interface.

Fig. 6 is a schematic diagram of a display control interface D0 corresponding to the two-screen control D, where, as shown in fig. 6, the display control interface D0 includes a display area D1, a return 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 for displaying a current running process of the second virtual display screen VS 2.

And returning to the one-screen control D2 for switching the content displayed by the second virtual display screen VS2 to the first virtual display screen VS1 for display. For example, for a certain process, if the current display content of the process is displayed on the second virtual display screen VS2, and if the user clicks the return one-screen control D2, the process is switched to the first virtual display screen VS1 to display, and at this time, the second virtual display screen VS2 may display a counter interface or a time interface.

And closing the two-screen control D3, wherein the content displayed by the second virtual display screen VS2 is switched to the first virtual display screen VS1 for display, and the second virtual display screen VS2 is turned off. For example, for a certain process, if the current display content of the process is displayed on the second virtual display screen VS2, and if the user clicks to close the two-screen control D3, the process is switched to the first virtual display screen VS1 to display, and at this time, the second virtual display screen VS2 is switched to the off-screen state, that is, the second virtual display screen VS2 does not display the content.

The touch area D4 is used for performing operation control on the second virtual display screen VS2 (the effect is similar to a notebook touch pad). According to the operation of the user in the touch area D4 acquired by the camera, mapping the operation of the user to the operation of the corresponding position of the second virtual display screen VS2 according to the mapping relation between the position of the user in the touch area D4 and the preset position, and then determining the control for executing the operation according to the position of the control of the second virtual display screen VS 2. For example, the user may control the screen pointer on the second virtual display screen VS2 through the touch area D4, so as to perform a corresponding operation.

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, an 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 screen VS1 and the second virtual display screen VS2 is explained.

In some embodiments, an application on the smart desk lamp may generate a process for the application on the smart 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 intelligent desk lamp include three types, the first being applications only shown on the first virtual display screen VS1, the applications may include interactive applications that the developer of the intelligent desk lamp is self-grinding, the second being applications only shown on the second virtual display screen VS2, the applications may include display applications of a third party, the third being applications that are shown on both the first virtual display screen VS1 and the second virtual display screen VS2, the applications may include comprehensive applications that the developer of the intelligent desk lamp is self-grinding, the first and second types of applications may be referred to as single-screen applications, and the third type of applications may be referred to as dual-screen applications. The interactive application may be an application that requires a user to perform a large number of operations, such as a game application, where the user needs to perform a manipulation in real time; a presentation class application may refer to an application that does not require user action, or that requires only a small amount of user action, such as a weather application, that does not require user action, or that only requires entry of a geographic location; the comprehensive application can refer to an application which needs to be operated by a user in some scenes and does not need to be operated by the user in some scenes, such as a notepad application, wherein the user needs to interact with the application when inputting an event, and the application only needs to display the event input by the user after the event is input.

In some embodiments, in order to enable the intelligent desk lamp to identify on which virtual display screen an application needs to be displayed, a screen identifier may be carried in an installation package of some applications, where the screen identifier may be a screen parameter, if the parameter is given by VS1, the screen identifier may be a first identifier, which indicates that the application is of a type that needs to be displayed on the first virtual display screen VS1, a process generated by the application after starting may be referred to as a first type of process, if the parameter is given by VS2, at this time, the screen identifier may be a second identifier, which indicates that the application is of a type that needs to be displayed on the second virtual display screen VS2, a process generated by the application after starting may be referred to as a second type of process, if the parameter is given by (VS 1, VS 2), and at this time, the screen identifier may be a third identifier, which indicates 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 VS 2. It should be noted that, for an application with a value of 3 for a screen parameter, at a certain moment, the application may display an interface on two display screens, or may display an interface on only one display screen. After these applications are installed on the smart desk lamp, screen identifiers may be stored in the installation information of these applications. In some embodiments, the screen identifier may not be carried in the installation package of some applications, and the smart desk lamp may default that the application needs to be displayed on the first virtual display screen VS1 or the second virtual display screen VS 2. After the applications are installed on the intelligent desk lamp, the intelligent desk lamp can add screen marks in the installation information of the applications.

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

In some embodiments, after the intelligent desk lamp is turned on, the controller of the intelligent desk lamp may create three application management stacks for storing the application displayed only on the first virtual display screen VS1, the application displayed only on the second virtual display screen VS2, and the screen usage information of the application provided with display screens on the first virtual display screen VS1 and the second virtual display screen VS2, respectively. The screen usage information can be the same as the screen identification in the installation information of the application program when the application is started, and can be changed along with the user operation if the display screen displayed by the application program is switched by the later 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 started, the controller of the intelligent desk lamp may not first create an application management stack, and after the user starts an application only displayed on the first virtual display screen VS1, create a first application management stack; after the user starts an application which is only displayed on the second virtual display screen VS2, a second application management stack is created; after the user starts an application with display pictures respectively set on the first virtual display screen VS1 and the second virtual display screen 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 can click an application program from a first starting page or a second starting page to generate an application starting instruction of the application program.

In some embodiments, the controller of the intelligent desk lamp is responsive to the application launch instruction to launch the application program, which upon launch generates at least one launch interface. If the application program is a double-screen application, generating two starting interfaces, wherein the application program can respectively set screen identifiers for the two starting interfaces, so that a controller can read the screen identifiers corresponding to the starting interfaces, and the two starting interfaces are projected onto corresponding virtual display screens according to the screen identifiers; if the application program is a single-screen application, a starting interface is generated, and 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 a controller can read the screen identifier corresponding to the starting interface, and the starting interface is projected onto a 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 to acquire the screen identification 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 a first application management stack; if the value of the screen identifier is VS2, the screen use information of the application program is added into a second application management stack; if the value of the screen identifier is (VS 1, VS 2), the screen use information of the application program is added into a third application management stack.

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

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

In some embodiments, if a user opens more applications, the memory resource consumption of the intelligent desk lamp will be larger, 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, a process control is used to be clickable on the first virtual display VS1 to manage the launched application.

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

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

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

In order to facilitate the user to understand the application currently running on the first virtual display screen VS1 and the application running on the second virtual display screen VS2, application windows of all the started applications may be displayed regularly.

In some embodiments, an application process may be presented in a regular manner by alternately ordering 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 the number of applications of one screen, where the number of applications of two screens is N, and the number of applications of one/two screens is Q, where one screen refers to an application whose current display screen is the first virtual display screen VS1, two screen refers to an application whose current display screen is the second virtual display screen VS2, and one/two screen 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 of alternately ordering different application processes may be: the priority of the first class process, the second class process and the third class process are the same, the first class process, the second class process and the third class process are alternately ordered according to the sequence of the first class process, the second class process and the third class process, and then the rest class processes are alternately ordered.

According to the ordering mode, if only the first type of process and the second type of process are running, when M is greater than or equal to N and N is greater than zero, the first N first type of process and the second N type of process are alternately displayed on the first 2N sequence bits on the process management page, and the remaining sequences of the remaining M-N first type of processes after the first 2N sequence bits are sequentially arranged. When M is smaller than N, the first M first type processes and the second M type processes are alternately displayed on the first 2M sequence bits on the process management page, and the remaining sequences of the remaining N-M second type processes after the first 2M sequence bits are sequentially arranged.

According to the ordering mode, if the running processes have a first type process, a second type process and a third type process, when M is greater than or equal to N, N is greater than or equal to Q, and Q is greater than zero, the first Q first type processes, the first Q second type processes and the Q third type processes are alternately displayed on the first 3Q sequence bits on the process management page, the N-Q first type processes and the N-Q second type 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 type processes are displayed on the subsequent sequence bits. When M is smaller than N, M and larger than Q, the first Q first type processes, the first Q second type processes and the Q third type processes are alternately displayed on the first 3Q sequence bits on the process management page, the M-Q first type processes and the M-Q second type processes are alternately displayed on the 2 (M-Q) sequence bits after the first 3Q sequence bits on the process management page, and the rest N-M second type processes are displayed on the subsequent sequence bits.

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

According to this ordering, when M is less than N, several specific ordering approaches 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 can alternately sequence the application processes of the two-screen application and the application processes of the one-screen application, and then alternately sequence the application processes of the rest two-screen application and the application processes of the one/two-screen application. Because the sum of M and Q is smaller than N, the application processes of a part of two-screen applications cannot be alternately ordered with the application processes with different screen use information, the application processes of the part of two-screen applications can be directly overlapped and displayed, and finally a group of overlapped processes are obtained. Sequencing effect referring to fig. 8, in fig. 8, the sequencing of application processes of the same screen usage information coincides with the sequencing 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 may first alternately sequence the application processes of the two-screen application and the application processes of the one-screen application, and then alternately sequence the application processes of the remaining two-screen application and the application processes of the one/two-screen application, so as to finally obtain a set of overlapped windows. Sequencing effect referring to fig. 9, in fig. 9, the sequencing of application processes of the same screen usage information is consistent in terms of the sequencing of the screen usage information within 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 can alternately sequence the application processes of the two-screen application and the application processes of the one-screen application, and then alternately sequence the application processes of the rest two-screen application and the application processes of the one/two-screen application. Because the sum of M and Q is larger than N, the application processes of a part of one/two screen application cannot be alternately ordered with the application processes with different screen use information, and the application processes of the part of one/two screen application can be directly overlapped and displayed, so that a group of overlapped windows is finally obtained. Sequencing effect referring to fig. 10, in fig. 10, the sequencing of application processes of the same screen usage information coincides with the sequencing of screen usage information within the respective application management stacks.

If M is greater than N, the processes of the started applications may be sorted by a method similar to the sorting method when M is less than N, where 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.

In some embodiments, after the controller sorts the first type of process, the second type of process and the third type of process according to the above-mentioned rule of alternating sorting, a process management page may be generated according to the sorted processes.

In some embodiments, in the process management page, the multiple processes perform vertical superposition display according to the above alternating sequence, the process in the sequence in front can form a shelter for a preset area of the process in the sequence in front, the preset area can be a lower area, and the superposition display mode of partial shelter can display more processes in a smaller area than the tiling display mode of all the processes. In some embodiments, an application process may also be displayed separately for application processes with different screen usage information in a regular manner. After the application process management module obtains the screen use information of the started application from each application management stack, the application process of the one-screen application can be displayed in a superposition manner, the application process of the two-screen application can be displayed in a superposition manner, and the application processes of the one/two-screen application can be displayed in a superposition manner, so that three groups of superposed display processes are obtained. The sorting effect can be seen in fig. 11, as shown in fig. 11, each type of process can be arranged separately, and different types of processes can be spaced by a preset distance, so that the user can distinguish and difference.

In fig. 11, the order of application processes of the same screen usage information coincides with the order of screen usage information within the respective application management stacks.

In some embodiments, after the application management process obtains the sequence of all application processes of the started application, a process management interface provided with a screen identifier VS1 may be generated according to the beat sequence, and then the application management process interface is sent to the desktop application control module according to the screen identifier VS1, so that the desktop application control module may display the process management interface on the first virtual display screen VS 1.

For example, referring to fig. 12, the process management interface may enable a user to manage a currently running process through a process management page, e.g., turn off, switch display screens, etc.

As shown in fig. 12, a plurality of processes currently running are displayed in a layered manner, and a user can select a process to be managed by scrolling up and down the processes. 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 current management process is switched, if the user clicks to select the current management process, the content of the current management process is directly displayed on the corresponding virtual display screen.

In addition, a tag a is provided in a corresponding area of a different process, and the tag a is used for identifying on which virtual display screen the process is currently displayed. The tag a may be determined according to the screen identifier, and if the screen identifier is VS1, the tag a may display "one screen", if the screen identifier is VS2, the tag a may display "two screens", and if the screen identifier is (VS 1, VS 2), the tag a may display "one screen+two screens". After an input process management instruction is received, acquiring an operating process and a position presented by the process, and displaying the positions presented before the instruction is received according to the application corresponding to the process (the first virtual display screen VS1 or the second virtual display screen VS 2) in the label sub-control of the process control controlled by the position presented before the instruction is received according to the application corresponding to the process, wherein the content displayed by the different label sub-control of the position presented before the instruction is received by the application corresponding to the process is different. For example, the label A1 corresponding to the first process in fig. 12 is "one screen", that is, indicates that the first process is displayed on the first virtual display screen VS1; the label A2 corresponding to the second process is a 'two-screen', namely the second process is displayed on a second virtual display screen VS2; the label A3 corresponding to the process three is "one screen+two screens", that is, the process three is displayed on the first virtual display screen VS1 and the second virtual display screen VS2 at the same time. At this time, if the user clicks the first selected process, the content corresponding to the first process is directly displayed on the first virtual display screen VS1; if the user clicks the selected process II, the content corresponding to the process II is directly displayed on a second virtual display screen VS2; if the user clicks to select the third process, the content corresponding to the third process is directly displayed on the first virtual display screen VS1 and the second virtual display screen VS 2.

It will be appreciated that the currently running processes may also be displayed in other forms, for example, tiled in the form of multiple widgets, etc., and the display forms of the processes are not limited in this application.

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

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

For example, the user may close the first process by clicking the first process closing control B1, close the second process by clicking the second process closing control B2, and close the third process by clicking the third process closing control B3. Thus, the user can pertinently close the process which needs to be closed.

In some embodiments, referring to fig. 12, the process management page is further provided with a one-button closing control B0, and when the number of processes that need to be closed currently is large, the user can close all the processes that run currently by clicking the one-button closing control B0, without clicking the process closing control corresponding to each process 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 the process shutdown operation is completed, if the user clicks on a space in the process management interface, the educational interface in the host interface is returned.

In some embodiments, after the user opens the process management page, the user may switch the virtual display screen corresponding to the currently running process, in addition to performing process closing management on the currently running process. In some embodiments, the user may display a screen switch to the process by applying display screen switch control C.

In some embodiments, application display screen toggling control C may include control C1 and control C2. The triggering mode of the control C1 can be that user operation sliding leftwards is received in a display area of the topmost process, an instruction for switching the application display screen can be generated after triggering, and the topmost process can be switched to the second virtual display screen VS2 in response to the instruction; the triggering manner of the control C2 may be that a user operation 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 screen CS1 in response to the triggering. As shown in FIG. 12, control C1 and control C2 may be simultaneously presented on a process management page. As shown in fig. 13, only control C1 may be displayed when the topmost application is a one-screen process. As shown in fig. 14, only control C2 may be displayed when the topmost application is a two-screen process.

In some embodiments, when the currently managed process is a process, the label A1 corresponding to the process is "one screen", that is, the process is displayed on the first virtual display screen VS1 before the process management instruction is received, at this time, the user may execute the left-sliding operation corresponding to the control C1 to switch the process to the second virtual display screen VS2 for displaying, at this time, the first virtual display screen VS1 does not display the content of the process, that is, the process is displayed in a different screen.

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

In some embodiments, when the currently managed process is the second process, the label A2 corresponding to the second process is "two-screen", that is, the second process is displayed on the second virtual display screen VS2 before receiving the process management instruction, at this time, the user may execute the right sliding operation corresponding to the control C2 to switch the second process to the first virtual display screen VS1 for display, at this time, the second virtual display screen VS2 does not display the content of the second process any more, that is, the second process is displayed in a different screen.

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

In some embodiments, when the currently managed process is the process three, the label A3 corresponding to the process three is "one screen+two screens", that is, the 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 execute the left-sliding operation corresponding to the control C1 to switch the process three to the second virtual display screen VS2 for displaying, at this time, the first virtual display screen VS1 does not display the content of the process three any more, that is, the process three is switched from the dual-screen display to the single-screen (second virtual display screen VS 2) for displaying. 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 third process to the first virtual display screen VS1 for display, where the second virtual display screen VS2 no longer displays the content of the third process, that is, switches the third process from the dual-screen display to the single-screen (the first virtual display screen VS 1) display. At this time, the second virtual display screen VS2 may display a counther interface or a time interface.

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

In some embodiments, control C1 is displayed when the currently managed process is currently displayed on first virtual display VS1 and can switch to display on second virtual display VS2 (e.g., process one in fig. 12), at which time control C2 is hidden.

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

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

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

Therefore, by setting the controls C1 and C2 as the conditions for hiding/displaying, the interference to the user when the user switches the display can be avoided.

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

In one embodiment, a plurality of intelligent table lamps can form a communication system through network connection, 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, a second number of second identity users, and so on.

As can be seen from the foregoing embodiments, in the embodiments of the present application, by alternately displaying, in a superimposed manner, an application process running on a first display screen, an application process running on a second display screen, and an application process running on the first display screen and the second display screen on a process management interface or displaying in a superimposed manner according to a display position, regular display of the application process is achieved, which is favorable for a user to view the processes on each display screen, facilitates the user to perform process management, and improves user experience.
