The specifics may be based on The actual use requirements are determined, which is not limited in the embodiment of the present invention.

The wearable device in the embodiment of the present invention may be: AR glasses, AR helmet, smart bracelet, smart watch, etc. It should be noted that the first wearable device and the second wearable device in the embodiment of the present invention may be the same wearable device (for example, both are AR glasses), or may be different wearable devices (for example, the first wearable device). The type device is AR glasses, and the second wearable device is a mobile phone), which is not limited in the embodiment of the present invention.

The virtual screen in the embodiment of the present invention may be any carrier that can be used to display the content projected by the projection device when the AR technology is used to display content. The projection device may be a projection device using AR technology, such as an electronic device, a wearable device, or an AR device in the embodiment of the present invention.

When AR technology is used to display content on a virtual screen, the projection device can project the virtual scene acquired (or internally integrated) by the projection device, or virtual scene and real scene onto the virtual screen, so that the virtual screen can display the content, thereby The user shows the effect of superimposing the real scene and the virtual scene.

Combined with different scenarios of AR technology application, the virtual screen can usually be any possible carrier such as the display screen of an electronic device (such as a mobile phone), the lens of AR glasses, the windshield of a car, the wall of a room, and so on.

The following takes the virtual screen as the display screen of the electronic device, the lens of the AR glasses, and the windshield of the car as examples to illustrate the process of displaying content on the virtual screen by using the AR technology.

In an example, when the virtual screen is the display screen of an electronic device, the projection device may be the electronic device.

When the user wears the glasses, the user can see the real scene in the area where he is located through the lens of the AR glasses, and the AR glasses can project the virtual scene acquired (or internally integrated) onto the lens of the AR glasses, so that The user can see the display effect of the real scene and the virtual scene superimposed through the lens of the AR glasses.

In another example, when the virtual screen is the windshield of a car, the projection device may be any electronic device. When the user is in the car, the user can see the real scene in the area through the windshield of the car, and the projection device can project the virtual scene acquired (or internally integrated) onto the windshield of the car , So that the user can see the display effect of the real scene and the virtual scene superimposed through the windshield of the car.

Of course, in the embodiment of the present invention, the specific form of the virtual screen may not be limited, for example, it may be a non-carrier real space. In this case, when the user is in the real space, the user can directly see the real scene in the real space, and the projection device can project the virtual scene acquired (or internally integrated) into the real space, so that The user can see the display effect of the real scene and the virtual scene superimposed in the real space.

The wearable device in the embodiment of the present invention may be a wearable device with an operating system. The operating system may be an Android operating system, an ios operating system, or other possible operating systems, which is not specifically limited in the embodiment of the present invention.

The following uses an operating system as an example to introduce the software environment to which the virtual screen synchronization method provided by the embodiment of the present invention is applied.

As shown in FIG. 1, it is a schematic structural diagram of a possible operating system provided by an embodiment of the present invention. In Figure 1, the architecture of the operating system includes 4 layers, namely: application layer, application framework layer, system runtime library layer, and kernel layer (specifically, it may be the Linux kernel layer).

Among them, the application layer includes various applications in the operating system (including system applications and third-party applications).

The application framework layer is the framework of the application. Developers can develop some applications based on the application framework layer while complying with the development principles of the application framework.

The system runtime layer includes a library (also called a system library) and an operating system runtime environment. The library mainly provides various resources required by the operating system. The operating system operating environment is used to provide a software environment for the operating system.

The kernel layer is the operating system layer of the operating system and belongs to the lowest level of the operating system software. The kernel layer provides core system services and hardware-related drivers for the operating system based on the Linux kernel.

Taking the operating system as an example, in the embodiment of the present invention, developers can develop a software program that implements the virtual screen synchronization method provided by the embodiment of the present invention based on the system architecture of the operating system shown in FIG. 1, so that the virtual screen The synchronization method can be run based on the operating system as shown in FIG. 1. That is, the processor or the wearable device can implement the virtual screen synchronization method provided by the embodiment of the present invention by running the software program in the operating system.

The following describes the virtual screen synchronization method according to the embodiment of the present invention with reference to the flowchart of the virtual screen synchronization method shown in FIG. 2. FIG. 2 is a schematic flowchart of a virtual screen synchronization method provided by an embodiment of the present invention. As shown in FIG. The virtual picture synchronization method provided by the embodiment of the invention includes the following steps 201 and 202:

Step 201: The first wearable device receives the first input of the user.

Exemplarily, the above-mentioned first input may include: a specific gesture input by the user, or a voice input by the user to the first wearable device, or the user input to a specific button on the first wearable device, or the user Specific posture. In an example, the above-mentioned specific gesture may be: a specific gesture input by the user in the shooting area of the camera of the first wearable device.

Exemplarily, the above-mentioned specific gesture may be any one of a sliding gesture, a palm hovering gesture, a click gesture, a long-press gesture, an area change gesture, a single-finger hovering gesture, and a multi-finger hovering gesture. There is no restriction on this.

Step 202: In response to the first input, the first wearable device synchronizes the virtual screen of the first virtual screen of the first wearable device to the second virtual screen of the second wearable device for display.

Wherein, the second wearable device is determined based on the target area in the shooting preview screen of the camera of the first wearable device, and the target area is the area selected by the first input.

Exemplarily, the target area selected by the user's first input may be a target area determined by the user through a button on the first wearable device or the user controls the first wearable device through voice input.

Exemplarily, the shooting preview picture of the first wearable device includes: a real picture taken by a camera of the first wearable device and a virtual picture generated based on the real picture.

Exemplarily, the aforementioned virtual picture is: virtual information generated by the aforementioned first wearable device according to a target object photographed by a camera set on the first wearable device. For example, when the picture captured by the camera of the first wearable device includes a table, the virtual picture may include: the length, width, and height of the table displayed on the first virtual screen in the form of a logo.

In an example, after the first wearable device synchronizes the virtual screen of the first virtual screen of the first wearable device to the second virtual screen of the second wearable device for display, when the second wearable device When the second virtual screen displays the target object, the second wearable device will mark the received virtual information on the target object.

Example 1, in the case that the second wearable device receives the length, width and height identification of the table synchronized by the first wearable device, when the second wearable device’s second virtual screen includes the table, the second wearable device The wearable device will display the length, width and height of the table on the second virtual screen.

Example 2: Taking the first wearable device and the second wearable device as AR glasses as an example, the user uses AR glasses 1 to play a game (for example, making a cake on the table). After the game is over, the user sets the AR glasses 1 The above virtual screen (for example, the cake made) is sent to the AR glasses 2 of other users. When the above table appears in the shooting preview screen of the AR glasses 2 of other users, the AR glasses 1 will be displayed in the shooting preview screen of the AR glasses 2 A synchronized virtual screen (for example, a cake made by the user of the AR glasses 1 is displayed on the table).

In another example, after the above-mentioned first wearable device synchronizes the virtual screen of the first virtual screen of the first wearable device to the second virtual screen of the second wearable device for display, the second wearable device may The virtual picture is displayed directly on the second virtual screen.

Example 3, taking the first wearable device and the second wearable device as AR glasses as an example, the user uses AR glasses 1 to play a game (for example, building a house with virtual building blocks), after the game is over, the user sets the AR glasses 1 The aforementioned virtual screen (for example, a house built by the user) is sent to the AR glasses 2 of other users, and the AR glasses 2 of other users can directly display the houses built by the user using the AR glasses 1.

Exemplarily, in response to the user's first input, the first wearable device determines the target area in the display area of its first virtual screen, and determines the wearable device within the range of the target area as the second wearable device.

Exemplarily, in a case where the first wearable device determines the second wearable device within the range of the target area, in order to synchronize the virtual screen of the first virtual screen of the first wearable device to the second wearable device of the second wearable device The virtual screen shows that the first wearable device needs to establish a connection with the second wearable device.

Optionally, the first wearable device may establish a communication connection between the first wearable device and the second wearable device before synchronizing the virtual screen. Exemplarily, before the above step 202, the virtual screen synchronization method provided in the embodiment of the present invention may further include the following steps 301 and 302:

Step 301: The first wearable device sends an infrared signal to the second wearable device through the infrared emitting device, the infrared signal includes: the device feature code of the first wearable device, so that the second wearable device can pass the device feature The code establishes a connection with the first wearable device.

Exemplarily, the first wearable device may include: an infrared transmitting device; the second wearable device may further include: an infrared receiving device.

Step 302: After receiving the infrared signal sent by the first wearable device, the infrared receiving device of the second wearable device establishes a connection with the first wearable device through the device feature code.

Exemplarily, after the connection between the first wearable device and the second wearable device is established, the first wearable device synchronizes the virtual screen of the first virtual screen to the second virtual screen of the second wearable device for display.

Exemplarily, in order to prevent a wearable device that is not selected by the user from receiving the infrared signal, the infrared signal sent by the first wearable device to the second wearable device is sent by directional transmission.

For example, when the user wants to enable the virtual screen synchronization function provided by the embodiment of the present invention, as shown in FIG. 3(A), it is the shooting preview screen of the first wearable device, which includes the virtual control 30 and the use of wearable Other users of the device. The user can start the virtual screen synchronization method provided by the embodiment of the present invention by overlapping the finger of one hand with the aforementioned virtual control 30 for 2 seconds.

Exemplarily, the first wearable device provided in the embodiment of the present invention is provided with an image acquisition device (for example, a camera). Taking the first wearable device as AR glasses as an example, the image capture device can capture the real-time picture image in front of the user who uses the first wearable device, so that the first wearable device can collect the real-time picture image from the collection. Recognize the user's specific gesture input in the camera shooting area of the first wearable device.

The virtual screen synchronization method provided by the embodiment of the present invention can be applied in a variety of scenarios, and it is convenient for the user to select the second wearable device with which the virtual screen needs to be synchronized by using different selection methods.

In the first possible scenario:

In this scenario, when the user needs to synchronize the virtual screen with multiple second wearable devices at the same time, he can create a selection box to select multiple second wearable The second wearable device achieves the above-mentioned purpose by performing virtual screen synchronization.

Optionally, in the embodiment of the present invention, in order to quickly select the second wearable device to reduce the data processing load of the first wearable device, the first wearable device may create a selection box to select the second wearable device.

Exemplarily, the foregoing step 202 may further include the following steps 202a and 202b:

Step 202a: In response to the first input, the first wearable device creates a selection box on the shooting preview screen.

Step 202b: The first wearable device determines the wearable device selected by the selection box as the second wearable device, and synchronizes the virtual screen to the second virtual screen of the second wearable device for display.

Exemplarily, the shape of the foregoing selection frame may be any possible shape such as a circle, a rectangle, a triangle, a diamond, a ring, or a polygon, which may be specifically determined according to actual usage requirements, and is not limited in the embodiment of the present invention.

For example, take a rectangular selection box as an example. When the first wearable device and the second wearable device are both AR glasses, as shown in Figure 3, the first virtual screen of the first wearable device displays a virtual screen synchronization function virtual control (as shown in Figure 3). 30), when the user wants to turn on the virtual screen synchronization function, the user's finger moves to the position where the synchronization function virtual control 30 is located and stays for 2 seconds to turn on the virtual screen synchronization function. After the screen synchronization function is turned on, as shown in Figure 3 As shown, the first wearable device will create a rectangular selection box (31 in Figure 3) on the display screen. Wherein, the selection box 31 is used to select the wearable device in the shooting preview screen of the first wearable device.

In this way, the first wearable device only needs to identify the wearable device in the selection box, which reduces the data processing load of the first wearable device and at the same time reduces the energy consumption of the first wearable device.

Further optionally, after the first wearable device creates the select box, the first wearable device can expand or reduce the range of the select box according to actual needs according to the specific input of the user.

Exemplarily, in the case where the foregoing first input includes: the first sub-input of the user's first hand and second hand, the foregoing step 202a may include the following steps 202a1 and 202a2:

Step 202a1. In the case where the first sub-input is included in the shooting preview screen of the first wearable device, based on the diagonal of the target rectangle, the first wearable device displays a selection box on the shooting preview screen.

Step 202a2, upon receiving the second sub-input of the user, the first wearable device updates the display of the selection box.

Wherein, the first sub-input is used to trigger the first wearable device to create a selection box, and the second sub-input is used to trigger the first wearable device to adjust the size of the selection box. The diagonal line of the target rectangle is the line between the first part of the first hand and the second part of the second hand.

Exemplarily, the first sub-input of the first hand and the second hand may be a gesture input of the user extending the fingers of both hands. When the first wearable device recognizes the gesture input, it displays on its shooting surface A selection box for selecting the second wearable device.

Exemplarily, the above-mentioned second sub-input may be a gesture input in which the user extends a finger in both hands and expands to both sides along the diagonal line (that is, the diagonal line of the above-mentioned selection box) or gathers in the middle. When the first wearable device recognizes the gesture of extending a finger with both hands in the shooting preview screen, it starts to create a frame selection area, creates a rectangular selection frame based on the diagonal line of the finger, and adjusts the selection by moving the fingers of both hands The size of the frame.

In an example, as shown in Figure 3(B), after the first wearable device recognizes the gesture of extending fingers with both hands of the user, the line connecting the fingertips of the fingers extending from the two hands is used as the diagonal of the rectangle Line, create a rectangular selection box 31, and adjust the size of the rectangular selection box 31 by moving your fingers. During this period, the two end points of the rectangular selection box 31 always move with the movement of the fingers.

In another example, as shown in Figure 4(A), after the first wearable device has turned on the screen synchronization function, it recognizes the user's hand gestures with fingers extending respectively, and will create a preset at the target position of the display screen. Set the size of the rectangular selection box. The user can move the fingers of both hands to the two end points of the rectangular selection frame 41, and adjust the size and position of the rectangular selection frame 41 by moving the fingers. For example, a rectangular selection frame 41 of a preset size created by the first wearable device can be adjusted to a selection frame 42 as shown in FIG. 4(B) according to the above method.

In this way, the user can display a selection frame on the shooting preview screen of the first wearable device through gesture input, and can adjust the size of the selection frame through gestures, so that the user can adjust the size of the selection frame to change the size of the selection frame. The wearable device whose screen is synchronized is included in the selection box.

Further optionally, after the user adjusts the selection box to an appropriate size, the size of the selection box needs to be locked to prevent the user from being able to adjust the size of the selection box when the user moves his finger out of the shooting preview screen.

Exemplarily, after the user completes the adjustment of the selection box, after the above step 202a2, the virtual screen synchronization method provided in the embodiment of the present invention may further include the following step 202a3:

Step 202a3: In the case of receiving the user's third sub-input, the first wearable device locks the display of the selection box.

Exemplarily, the above-mentioned third sub-input may be a gesture input of the user spreading the palms of both hands. When the first wearable device detects the gesture input of spreading the palms of the user's hands in the shooting preview screen, the size of the selection box is locked.

Exemplarily, the above-mentioned locking the size of the selection box includes: fixing the size and position of the selection box.

Exemplarily, when the first wearable device detects the gesture of spreading the palms of the user's hands, the creation of the selection box is completed, and the wearable device contained in the selection box is determined as the second wearable device. For example, taking the first wearable device and the second wearable device as AR glasses as an example, as shown in Figure 5, when the AR glasses recognize that the user's gesture in the display screen becomes a gesture of spreading the palms of both hands, the selection box is completed 31 is created, and it is recognized whether the user wearing AR glasses is included in the selection frame, and at the same time, the AR glasses in the selection frame are searched, and the screen is displayed synchronously to them.

In this way, when the user locks the size of the selection box through gesture input with open palms of both hands, the user can safely put his hands down without affecting the size of the selection box.

Optionally, when the selection frame of the first wearable device shooting preview screen is locked, and the first wearable device determines the second wearable device from the selection frame, it is necessary to mark the second wearable device in the selection frame Location.

Exemplarily, after the wearable device selected by the selection box is determined to be the second wearable device in step 202b, the virtual screen synchronization method provided in the embodiment of the present invention further includes the following step 202b1:

Step 202b1, the first wearable device displays the first logo in the first area on the shooting preview screen.

The first identifier is used to mark the second wearable device, and the first area is the area where the second wearable device is located.

Exemplarily, the above-mentioned first area is the area where the second wearable device is located in the selection frame in the shooting preview screen of the first wearable device. The first wearable device reminds the user that the second wearable device is in the shooting preview screen Location, the first logo is displayed within the area where the second wearable device is located.

Exemplarily, the first mark may be a red dot, and the red dot is displayed in the first area to mark the second wearable device in the shooting preview screen of the first wearable device.

For example, taking the first wearable device and the second wearable device as AR glasses as an example, referring to FIG. 5, when the user completes the creation of the selection frame 31, the first wearable device recognizes the user wearing the AR glasses in the selection frame 31 , And search the AR glasses within the selection frame 31 at the same time, and display the origin mark (that is, the above-mentioned first mark, 32 in Fig. 5) at the position of the two AR glasses in the selection frame 31, thereby marking the AR glasses s position.

In this way, the user can clearly see the position of the second wearable device in the selection frame of the shooting preview screen of the first wearable device, which is convenient for the user to perform secondary screening.

Optionally, since the above selection box is rectangular, the selection range is large, and it is likely to include wearable devices with which the user does not want to synchronize the virtual screen. At this time, the user can filter the second wearable devices in the selection box.

Exemplarily, after the above step 202b1, the virtual picture synchronization method provided in the embodiment of the present invention may include the following step 202b2:

Step 202b2, when the second wearable device is blocked by the target object, the first wearable device cancels the display of the first logo.

Exemplarily, the aforementioned target object may be the palm of the user, or other opaque objects.

Exemplarily, using the target object to block the second wearable device is to prevent the blocked wearable device from appearing in the selection frame of the shooting preview screen of the first wearable device. In this way, the first wearable device does not Determine it as the second wearable device.

Exemplarily, the above-mentioned target object is also used to block the infrared signal sent by the first wearable device to the second wearable device.

Exemplarily, taking the first wearable device and the second wearable device as both AR glasses as an example, when the user completes the creation of the selection box, if there are AR glasses that the user does not want to synchronize with the virtual screen in the selection box , As shown in Figure 6, use the one-hand palm open gesture to cover the AR glasses for 2 seconds, the object that is hidden by the one-hand palm open gesture will be deselected, and the first mark of the AR glasses position disappears, making the first The display screen of the wearable device will not be synchronized to the display area of the second wearable device that is hidden by the open palm gesture of one hand.

In this way, when the selection frame of the shooting preview screen of the first wearable device contains a second wearable device that the user does not want to synchronize with the virtual screen, the second wearable device can be blocked to prevent the virtual screen from being performed with it. Synchronize.

In the second possible scenario:

In this scenario, when the user is inconvenient to use gestures to create a selection box, the user can drive the first wearable device to rotate by turning his head to align the second logo displayed on the first virtual screen of the first wearable device In the second wearable device mode, the virtual screen of the first wearable device is synchronized to the second wearable device.

Optionally, before step 202, the virtual screen synchronization method provided in the embodiment of the present invention may include the following step 202c1:

Step 202c1, the first wearable device displays the second identifier at the target location of the target area.

Exemplarily, in combination with the foregoing step 202c1, after step 202c1, the foregoing step 202 may further include the following step 202c2:

Step 202c2: The first wearable device determines the wearable device in the second area including the second identifier as the second wearable device, and synchronizes the virtual screen to the second virtual screen display of the second wearable device.

Exemplarily, after the first wearable device determines the target area, the second identifier is displayed at the target location of the target area. The target area may be the entire display area of the shooting preview screen of the first wearable device, and the target position may be the center position of the aforementioned target area.

Exemplarily, the above-mentioned second mark may be a cross auxiliary line, or may be an image, or may be another mark used to mark the second wearable device, which is not limited in the embodiment of the present invention.

Exemplarily, when the above-mentioned second identifier is located within the area range of the second area, the first wearable device determines the wearable device within the second area range as the second wearable device.

Exemplarily, the foregoing second area is an area where the second wearable device is located.

In this way, when the user wants to synchronize the virtual screen with a wearable device, he only needs to align the second mark displayed on the shooting preview screen of the first wearable device with the wearable device (that is, all or part of both). Position overlap), the wearable device can be determined as the second wearable device, and the virtual screen can be synchronized with it.

Optionally, the user can control the rotation of the first wearable device by rotating the head, and align the second mark displayed on the shooting preview screen with the wearable device with which the user wants to synchronize the virtual screen.

Exemplarily, after the above step 202c1, the virtual screen synchronization method provided in the embodiment of the present invention may include the following steps 202c3 and 202c4:

Step 202c3: The first wearable device obtains the rotation direction and the rotation angle of the first wearable device;
