Description

TECHNICAL FIELD

[0001] The present application relates to the field of virtual reality technology, and in particular to a video playing method and device. BACKGROUND

[0002] Virtual reality (VR) technology is a technology that can construct a panoramic video by collecting data from the real world. With the progress of VR technology, the panoramic video that can be constructed by VR technology is increasingly close to reality, and VR technology is widely used in daily life. Users can adjust the playing angle of a VR video to watch different areas of the VR video. For example, in the field of real estate sales and real estate decoration, a panoramic video of a house can be constructed by using VR technology, so that users can realize online house viewing through the panoramic video of the house, and users can watch different rooms of the house by adjusting the playing angle of the panoramic video of the house.

[0003] However, in the existing VR technology, the way in which users adjust the playing angle of a video lacks interactivity, resulting in reduced user immersion and poor user experience. SUMMARY

[0004] The present application provides a video playing method and device, which can improve the interactivity when a user adjusts the playing angle of a video. To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0005] In a first aspect, the present application provides a video playing method, which comprises: first collecting target information, and then adjusting the playing angle of a video according to the target information. The target information includes user facial orientation information and user movement information, the user facial orientation information is used to represent the direction in which the user's face is oriented, and the user movement information is used to represent the direction in which the user moves.

[0006] In the video playing method provided by the present application, when a user adjusts the playing angle of a video, the user does not need to manipulate a mouse or touch a screen, but can directly change the facial orientation and move the body, so that the playing angle of the video is adjusted according to the user's actions. Therefore, the interactivity when a user adjusts the playing angle of a video is improved, the user's immersion when watching a video is increased, and the user experience is improved.

[0007] In a possible implementation manner, the above-mentioned adjusting the playing angle of a video according to the target information can include: adjusting the orientation of the playing angle according to the user facial orientation information; and adjusting the position of the playing angle according to the user movement information.

[0008] In the video playing method provided by the present application, when adjusting the playing angle of the video, the user can not only change the face orientation to adjust the orientation of the playing angle, but also move to adjust the position of the playing angle. For example, when the user wants to move the orientation of the playing angle of the video upward, the user can adjust the orientation of the playing angle of the video upward by lifting the head. For another example, when the user wants to move the position of the playing angle of the video forward, the user can adjust the position of the playing angle of the video forward by moving forward.

[0009] In a possible implementation, the adjusting the orientation of the playing angle according to the user face orientation information comprises: determining an orientation adjusting direction of the playing angle according to the user face orientation information; and adjusting the orientation of the playing angle according to the orientation adjusting direction and a preset orientation adjusting amount.

[0010] For example, the direction of the user face orientation is downward, and the preset orientation adjusting amount is 30 degrees. The video playing device first determines the orientation adjusting direction of the playing angle to be downward according to the user face orientation information, and then adjusts the orientation of the playing angle downward by 30 degrees.

[0011] Optionally, the user face orientation information can also be used to represent the angle of the user face orientation.

[0012] In another possible implementation, the adjusting the orientation of the playing angle according to the user face orientation information can comprise: determining adjusting information according to the user face orientation information; and adjusting the orientation of the playing angle according to the adjusting information. The adjusting information is used to represent the direction of the adjusted orientation of the playing angle and the angle of the orientation of the playing angle.

[0013] Optionally, the direction of the adjusted orientation of the playing angle can be the same as the direction of the user face orientation.

[0014] Optionally, the angle of the adjusted orientation of the playing angle can be the same as the angle of the user face orientation.

[0015] For example, the user face orientation is upward by 45 degrees, and the current orientation of the playing angle is downward by 30 degrees. The video playing device first determines the adjusted orientation of the playing angle to be upward by 45 degrees according to the user face orientation information, and then adjusts the orientation of the playing angle upward by 75 degrees to adjust the orientation of the playing angle from downward by 30 degrees to upward by 45 degrees. It can be seen that the adjusted orientation of the playing angle (direction and angle) is the same as the user face orientation.

[0016] It can be understood that when a user watches a video played by an electronic device, the face direction of the user is usually directly to the screen of the electronic device. After the user changes the face direction, the face direction of the user can no longer be directly to the screen of the electronic device. Therefore, the user can not continue to watch the video played by the electronic device after changing the face direction.

[0017] To this end, the user can adjust the orientation of the playing view angle in a manner of changing the face direction and returning to the original face direction. That is, the user can first change the face direction and then return to the original face direction (hereinafter referred to as a returning process). During the process of changing the face direction, the video playing device can generate user face direction information according to the face direction of the user, and then adjust the orientation of the playing view angle according to the information. During the returning process, the video playing device does not generate user face direction information according to the face direction of the user, and does not adjust the orientation of the playing view angle.

[0018] In a possible implementation, adjusting the position of the playing view angle according to the user movement information comprises: determining a position adjustment direction of the playing view angle according to the user movement information; and adjusting the position of the playing view angle according to the position adjustment direction and a preset position adjustment amount.

[0019] For example, the user moves forward, and the preset movement adjustment amount is N. The video playing device first determines that the position adjustment direction of the playing view angle is forward according to the user movement information, and then adjusts the position of the playing view angle by N forward.

[0020] Optionally, the user movement information further represents a distance of the movement of the user.

[0021] In another possible implementation, adjusting the position of the playing view angle according to the user movement information comprises: determining a position adjustment direction and a position adjustment distance of the playing view angle according to the user movement information; and adjusting the position of the playing view angle according to the position adjustment direction and the position adjustment distance.

[0022] Optionally, there can be a conversion relationship between the position adjustment distance and the user movement distance, which can be: position adjustment distance = user movement distance * (second distance / first distance). Wherein, the first distance is the vertical distance between the user and the boundary of the first target region in the user movement direction, the second distance is the vertical distance between the position of the playing view angle and the boundary of the second target region in the user movement direction, the second region is a two-dimensional plane region corresponding to the video, * is a multiplication sign, and / is a division sign. For example, the user movement distance is 30, the first distance is 100, and the second distance is 200, and then the position adjustment distance is 30 * (200 / 100) = 60.

[0023] Exemplarily, taking the user moving M1 backward as an example. The video playing device first determines, according to the user movement information, that the position adjustment direction of the playing perspective is to be adjusted backward by a distance M2, and then adjusts the position of the playing perspective backward by M2.

[0024] wherein M2=M1*(a / b), a is the first distance, i.e. the vertical distance between the user and the first region boundary at the rear, and b is the second distance, i.e. the vertical distance between the position of the playing perspective and the second region boundary at the rear.

[0025] It can be understood that if the user adjusts the orientation of the playing perspective by changing the face orientation and returning to the normal, the second distance corresponding to the same user movement direction before and after adjusting the orientation of the playing perspective can change. Therefore, the user can change the orientation of the playing perspective by changing the face orientation and returning to the normal after moving to the boundary of the first region so as to watch other positions of the video.

[0026] In a possible manner, the collecting target information can include: collecting the target information by a collecting unit, the collecting unit including at least one of an image collecting unit, a sound collecting unit or an infrared collecting unit.

[0027] In another possible implementation manner, the collecting target information can include: receiving collecting information sent by a collecting device, the collecting information including the target information.

[0028] In a second aspect, the present application further provides a video playing device, which includes a processing unit, the processing unit being configured to: collect target information, the target information including user face orientation information and user movement information, the user face orientation information being used to represent the direction of the user face orientation, and the user movement information being used to represent the direction of the user movement; and adjust the playing perspective of the video according to the target information.

[0029] In a possible implementation manner, the processing unit is specifically configured to: adjust the orientation of the playing perspective according to the user face orientation information; and adjust the position of the playing perspective according to the user movement information.

[0030] In a possible implementation manner, the processing unit is specifically configured to: determine the orientation adjustment direction of the playing perspective according to the user face orientation information; and adjust the orientation of the playing perspective according to the orientation adjustment direction and a preset orientation adjustment amount.

[0031] Optionally, the user face orientation information can also be used to represent the angle of the user face orientation.

[0032] In another possible implementation manner, the processing unit is specifically configured to: determine adjustment information according to the user face orientation information, the adjustment information being used to represent a direction of an adjusted orientation of the play view and an angle of the adjusted orientation of the play view; and adjust the orientation of the play view according to the adjustment information.

[0033] Optionally, the direction of the adjusted orientation of the play view and the direction of the user face orientation can be the same.

[0034] Optionally, the angle of the adjusted orientation of the play view and the angle of the user face orientation can be the same.

[0035] In a possible implementation manner, the processing unit is specifically configured to: determine a position adjustment direction of the play view according to the user movement information; and adjust the position of the play view according to the position adjustment direction and a preset position adjustment amount.

[0036] Optionally, the user movement information is also used to represent a distance of user movement.

[0037] In another possible implementation manner, the processing unit is specifically configured to: determine a position adjustment direction and a position adjustment distance of the play view according to the user movement information; and adjust the position of the play view according to the position adjustment direction and the position adjustment distance.

[0038] Optionally, there can be a conversion relationship between the position adjustment distance and the user movement distance, and the conversion relationship can be: position adjustment distance = user movement distance * (second distance / first distance).

[0039] In a possible implementation manner, the processing unit is specifically configured to: acquire the target information by an acquisition unit, the acquisition unit including at least one of an image acquisition unit, a sound acquisition unit or an infrared acquisition unit.

[0040] In another possible implementation manner, the processing unit is specifically configured to: receive acquisition information sent by an acquisition device, the acquisition information including the target information.

[0072] In daily life, a user can watch different areas of a VR video by adjusting a play view angle of the VR video.

For example, the notification manager can display text information in the status bar, or can also issue a prompt sound, for example, a vibration of the electronic device, a flashing of an indicator light, etc.

[0104] The runtime includes a core library and a virtual machine. The runtime is responsible for scheduling and management of the operating system. The core library includes two parts: one part is a function function required to be called by the java language, and the other part is the core library of the operating system.

[0111] For ease of understanding, the following embodiments of the present application will take an electronic device with the structure shown in FIGS. 1 and 2 as an example to introduce the video playing method provided by the embodiments of the present application. Figure 1 and Figure 2 The video playing method provided by the embodiments of the present application is introduced by taking an electronic device with the structure shown in FIGS. 1 and 2 as an example.

[0112] The technical solutions involved in the following embodiments can be implemented in the electronic device 100 with the hardware architecture and the software architecture described above.

[0113] The technical solutions provided by the embodiments of the present application are described in detail by taking the electronic device 100 as a smart screen and in combination with the accompanying drawings.

[0114] Figure 3 is a graphical user interface (GUI) schematic diagram provided by the embodiments of the present application, Figure 3 The screen display system of the smart screen shows the interface content currently output, which is the main interface of the smart screen. The interface content shows multiple application programs (Apps), such as VR, clock, calendar, gallery, memo, etc. It can be understood that the interface content can also include more application programs, which are not limited by the embodiments of the present application.

[0115] The user can instruct the smart screen to start the VR application by touching a specific control on the screen of the smart screen, pressing a specific physical button or button combination, inputting voice, air gesture, etc. In response to receiving the instruction of the user to start the VR application, the smart screen starts the VR application.

[0116] For example, the user can click the "VR" application icon on the main interface by operating the remote controller of the smart screen to instruct the smart screen to start the VR application.

[0117] For another example, the user can instruct the smart screen to start the VR application and display the VR application interface by voice instruction (such as "open the VR application").

[0118] The user can play various videos through the VR application interface. The above-mentioned videos include but are not limited to VR videos, panoramic videos, VR panoramic videos, VR real scene videos, or 3D panoramic videos.

[0119] As shown in Figure 4 , the VR application is a VR house viewing application, and the user can instruct the smart screen to play a 3D panoramic video of a house through the application to view the interior of the house. It can be understood that the VR application can also be other VR applications, and the user can also play other videos through the VR application, such as videos of scenic spots, videos of shopping malls, or other videos.

[0120] The specific method of generating the above video can be processed by any method that can be thought of by those skilled in the art, and the embodiments of the present application do not make specific limitations thereto. For example, the video is generated by collecting real scene images through a panoramic camera.

[0121] As shown in Figure 5 , the user can also instruct the smart screen to play a preview navigation map (also referred to as a VR panoramic video navigation map) of the video, and the user can determine the position and orientation of the current play view within the entire video through the preview navigation map. The preview navigation map is a plan view for indicating the position and orientation of the current play view within the entire video.

[0122] As shown in Figure 6 , when the user wants to adjust the play view of the video, the user can indicate the play view of the VR application video by moving in the viewer activity area (hereinafter referred to as the first area). The first area can be an area defined in front of an electronic device (such as a smart screen) to limit the user's viewing of the video, which is usually a rectangular area where the user's position and the user's face orientation can be clearly captured by the collection device (such as a camera). The user's position in the first area is referred to as the viewer position.

[0123] Optionally, the initial position of the play view can be the center of the second area. The initial orientation of the play view can be forward. The second area is a two-dimensional planar area corresponding to the video.

[0124] Optionally, as shown in Figure 7 , the second area can be generated according to the maximum length and maximum width of the graph corresponding to the video. Wherein, Figure 7 The left side is the graph corresponding to the video, Figure 7 The right side is the second area.

[0125] As shown in Figure 8As shown, in the first area, the user is watching a video of the house through the smart screen in front of them. When the user wants to move the playback viewpoint of the video forward, the user can move forward M1 in the first area. The smart screen obtains the user's movement information (i.e., information used to characterize the user's movement direction and distance) through a collection device (such as a camera) and measures the distance between the user and the boundary of the first area in front (hereinafter referred to as the first distance) as a. Then, the smart screen obtains the distance between the current viewpoint position and the boundary of the second area in front (hereinafter referred to as the second distance) as b. After that, the smart screen first determines the position adjustment direction of the playback viewpoint to be forward based on the user's movement information, and then determines the position adjustment distance of the playback viewpoint as M1*(a / b) = M2 based on the user's movement information, the first distance and the second distance. Finally, the playback viewpoint of the video is moved forward M2.

[0126] For example, such as Figure 9 As shown, in the first area, a user is watching a video of their home through a smart screen in front of them. When the user wants to move the video playback angle 90 degrees to the left, they can rotate their face 90 degrees to the left in the first area. The smart screen obtains the user's facial orientation information (i.e., information representing the direction and angle of the user's face) through a data acquisition device. Then, the smart screen first determines the direction of the playback angle adjustment to the left based on the user's facial orientation information, then determines the angle of the playback angle adjustment to 90 degrees based on the user's facial orientation information, and finally adjusts the video playback angle 90 degrees to the left. Figure 9 As can be seen, before the adjustment, the playback view was facing the left side of the second area. After adjusting the playback view to the left by 90 degrees, the playback view is now facing the front of the second area.

[0127] Understandably, users can also adjust the viewing angle of the video by turning their face up or down (i.e., looking up or down).

[0128] For example, such as Figure 10 As shown, in the first area, the user is watching a video of the house through the smart screen in front of them. When the user wants to move the video playback viewpoint backward, the user can move backward by M3 in the first area. The smart screen obtains the user's movement information through the acquisition device and measures the distance between the user and the boundary of the first area behind them as 'a'. Then, the smart screen obtains the distance between the current viewpoint position and the boundary of the second area behind them as 'b'. After that, the smart screen first determines the direction of the playback viewpoint adjustment to be backward based on the user's movement information, and then determines the playback viewpoint adjustment distance as M3*(a / b) = M4 based on the user's movement information, the first distance, and the second distance. Finally, the playback viewpoint position of the video is moved backward by M4.

[0129] For example, such asFigure 11 As shown in FIG. 1, a user is watching a video of a house through the smart screen in front of the first region, when the user wants to move the playing perspective position of the video to the right, the user can move M5 to the right in the first region, the smart screen obtains the user movement information through the acquisition device and measures the distance between the user and the right boundary of the first region as a, then the smart screen obtains the distance between the current perspective position and the right boundary of the second region as b, then the smart screen first determines that the adjustment direction of the playing perspective position is to the right according to the user movement information, then determines the adjustment distance of the playing perspective position as M5*(a / b)=M6 according to the user movement information, the first distance and the second distance, and finally moves the playing perspective position of the video backward by M6.

[0130] The specific method of collecting the user face orientation information, collecting the user movement information and measuring the distance can be any method that can be thought of by those skilled in the art, and the embodiments of the present application do not make specific limitations thereon. For example, the user face orientation information and the user movement information can be collected by infrared detection, wearable sensors, indoor positioning, etc.

[0131] The smart screen can also simulate events (such as touch gesture events, voice events, etc.) to adjust the playing perspective of the video according to the user face orientation information and the user movement information.

[0132] Exemplarily, the VR application supports left swipe, right swipe, up swipe, down swipe, double-click touch gesture events to adjust the playing perspective of the video. Among them, the left swipe touch gesture event corresponds to adjusting the orientation of the playing perspective to the right, the right swipe touch gesture event corresponds to adjusting the orientation of the playing perspective to the left, the up swipe touch gesture event corresponds to adjusting the orientation of the playing perspective downward, the down swipe touch gesture event corresponds to adjusting the orientation of the playing perspective upward, and the double-click touch gesture event corresponds to adjusting the position of the playing perspective forward. When the user watches the video through the VR application, the smart screen can collect and simulate the above-mentioned touch gesture events to adjust the playing perspective of the video according to the user face orientation information and the user movement information. For example, the user face orientation information collected by the smart screen indicates that the direction of the user's face orientation is upward (i.e. lifting the head), then the smart screen can simulate the down swipe touch gesture event according to the information, thereby adjusting the orientation of the playing perspective upward. For another example, the user movement information collected by the smart screen indicates that the direction of the user's movement is forward, then the smart screen can simulate the double-click touch gesture event according to the information, thereby adjusting the position of the playing perspective forward.

[0133] The video playing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0134] As shown in FIG. 1, the embodiments of the present application provide a video playing method, which comprises: Figure 12 As shown in FIG. 1, the embodiments of the present application provide a video playing method, which comprises:

[0135] S1201, the video playing apparatus collects target information.

[0136] The target information includes user face orientation information and user movement information, the user face orientation information is used to represent a direction of the user face orientation, and the user movement information is used to represent a direction of the user movement.

[0137] In a possible manner, the video playing apparatus can collect the target information through a collecting unit, and the collecting unit includes at least one of an image collecting unit, a sound collecting unit, or an infrared collecting unit.

[0138] In another possible implementation manner, the video playing apparatus can receive collecting information sent by a collecting apparatus. The collecting information includes the target information.

[0139] Optionally, the user face orientation information can also be used to represent an angle of the user face orientation.

[0140] Optionally, the user movement information can also be used to represent a distance of the user movement.

[0141] S1202, the video playing apparatus adjusts a playing perspective of a video according to the target information.

[0142] In a possible implementation manner, the video playing apparatus can first adjust a direction of the playing perspective according to the user face orientation information, and then adjust a position of the playing perspective according to the user movement information.

[0143] In a possible implementation manner, the adjusting the direction of the playing perspective according to the user face orientation information includes: determining a direction adjustment direction of the playing perspective according to the user face orientation information; and adjusting the direction of the playing perspective according to the direction adjustment direction and a preset direction adjustment amount.

[0144] For example, the direction of the user face orientation is downward, and the preset direction adjustment amount is 30 degrees. The video playing apparatus first determines the direction adjustment direction of the playing perspective as downward according to the user face orientation information, and then adjusts the direction of the playing perspective by 30 degrees downward.

[0145] In another possible implementation manner, the adjusting the direction of the playing perspective according to the user face orientation information can include: determining adjustment information according to the user face orientation information; and adjusting the direction of the playing perspective according to the adjustment information. The adjustment information is used to represent a direction of the adjusted direction of the playing perspective and an angle of the adjusted direction of the playing perspective.

[0146] Optionally, the direction of the adjusted direction of the playing perspective can be the same as the direction of the user face orientation.

[0147] Optionally, the angle of the adjusted direction of the playing perspective can be the same as the angle of the user face orientation.

[0148] For example, taking the case that the user's face orientation is 45 degrees upward and the current viewing angle orientation is 30 degrees downward. The video playing device first determines the adjusted viewing angle orientation to be 45 degrees upward according to the user's face orientation information, and then adjusts the viewing angle orientation upward by 75 degrees to adjust the viewing angle orientation from 30 degrees downward to 45 degrees upward. It can be seen that the adjusted viewing angle orientation (direction and angle) is the same as the user's face orientation.

[0149] It can be understood that when the user watches the video played by the electronic device, the user's face orientation is usually directly facing the screen of the electronic device. After the user changes the face orientation, the user's face orientation can no longer be directly facing the screen of the electronic device. Therefore, the situation that the user cannot continue to watch the video played by the electronic device after changing the face orientation can occur.

[0150] To this end, the user can adjust the viewing angle orientation in the manner of changing the face orientation and returning to the original face orientation. That is, the user can first change the face orientation, and then return to the original face orientation (hereinafter referred to as the returning process). During the process of changing the face orientation, the video playing device can generate the user's face orientation information according to the user's face orientation, and then adjust the viewing angle orientation according to the information. During the returning process, the video playing device does not generate the user's face orientation information according to the user's face orientation, and does not adjust the viewing angle orientation.

[0151] In a possible implementation, the above-mentioned adjusting the position of the viewing angle according to the user movement information comprises: determining the position adjustment direction of the viewing angle according to the user movement information; and adjusting the position of the viewing angle according to the position adjustment direction and a preset position adjustment amount.

[0152] For example, taking the case that the user moves forward and the preset movement adjustment amount is N. The video playing device first determines the position adjustment direction of the viewing angle to be forward according to the user movement information, and then adjusts the position of the viewing angle forward by N.

[0153] In another possible implementation, the adjusting the position of the viewing angle according to the user movement information comprises: determining the position adjustment direction of the viewing angle and the position adjustment distance of the viewing angle according to the user movement information; and adjusting the position of the viewing angle according to the position adjustment direction and the position adjustment distance.

[0154] Optionally, there can be a conversion relationship between the position adjustment distance and the user movement distance, which can be: position adjustment distance = user movement distance * (second distance / first distance). Wherein, the first distance is the vertical distance between the user and the first target region boundary in the user movement direction, the second distance is the vertical distance between the position of the play view and the second target region boundary in the user movement direction, the second region is a two-dimensional plane region corresponding to the video, * is multiplication, and / is division. For example, the user movement distance is 30, the first distance is 100, and the second distance is 200, and then the position adjustment distance is 30 * (200 / 100) = 60.

[0155] Exemplarily, taking the user moving backward by M1 as an example. The video playing device first determines the position adjustment direction of the play view to be backward adjustment distance M2 according to the user movement information, and then adjusts the position of the play view backward by M2.

[0156] Wherein, M2 = M1 * (a / b), a is the first distance, i.e., the vertical distance between the user and the first region boundary behind, and b is the second distance, i.e., the vertical distance between the position of the play view and the second region boundary behind.

[0157] It can be understood that if the user adjusts the orientation of the play view by changing the facial orientation and returning to the normal, the second distance corresponding to the same user movement direction before and after adjusting the orientation of the play view can change. Therefore, the user can change the orientation of the play view by changing the facial orientation and returning to the normal after moving to the boundary of the first region so as to watch other positions of the video.

[0158] For example, Figure 9 In the case where the user's facial orientation is not rotated 90 degrees to the left, the user's face and the play view are both forward, and if the user moves backward, the second distance used in calculating the position movement distance of the play view is the vertical distance between the position of the play view and the second region boundary behind. After the user's facial orientation is rotated 90 degrees to the left and returned to the normal, the user's face is forward but the play view is right, and if the user moves backward, the second distance used in calculating the position movement distance of the play view is no longer the vertical distance between the position of the play view and the second region boundary behind, but the vertical distance between the position of the play view and the second region boundary to the left.

[0159] It can be seen that in the video playing method provided by the application, the user can directly change the facial orientation and move the body to adjust the play view of the video according to the user's action without manipulating the mouse or touch screen, thereby improving the interaction when the user adjusts the play view of the video, increasing the immersion when the user watches the video, and improving the user experience.

[0160] The embodiment of the present application further provides a video playing device, which comprises a processing unit, and the processing unit is used for: collecting target information, wherein the target information comprises user face orientation information and user movement information, the user face orientation information is used for representing a direction of user face orientation, and the user movement information is used for representing a direction of user movement; and adjusting a playing perspective of a video according to the target information.

[0161] In a possible implementation, the processing unit is specifically used for: adjusting the direction of the playing perspective according to the user face orientation information; and adjusting the position of the playing perspective according to the user movement information.

[0162] In a possible implementation, the processing unit is specifically used for: determining a direction adjustment direction of the direction of the playing perspective according to the user face orientation information; and adjusting the direction of the playing perspective according to the direction adjustment direction and a preset direction adjustment amount.

[0163] Optionally, the user face orientation information can also be used for representing an angle of user face orientation.

[0164] In another possible implementation, the processing unit is specifically used for: determining adjustment information according to the user face orientation information, wherein the adjustment information is used for representing a direction of the direction of the adjusted playing perspective and an angle of the direction of the playing perspective; and adjusting the direction of the playing perspective according to the adjustment information.

[0165] Optionally, the direction of the direction of the adjusted playing perspective can be the same as the direction of the user face orientation.

[0166] Optionally, the angle of the direction of the adjusted playing perspective can be the same as the angle of the user face orientation.

[0167] In a possible implementation, the processing unit is specifically used for: determining a position adjustment direction of the position of the playing perspective according to the user movement information; and adjusting the position of the playing perspective according to the position adjustment direction and a preset position adjustment amount.

[0168] Optionally, the user movement information can also be used for representing a distance of user movement.

[0169] In another possible implementation, the processing unit is specifically used for: determining a position adjustment direction and a position adjustment distance of the position of the playing perspective according to the user movement information; and adjusting the position of the playing perspective according to the position adjustment direction and the position adjustment distance.

[0170] Optionally, a conversion relationship can exist between the position adjustment distance and the distance of user movement, and the conversion relationship can be: position adjustment distance = distance of user movement * (second distance / first distance).

[0171] In a possible implementation, the processing unit is specifically configured to: collect the target information by a collecting unit, the collecting unit comprising at least one of an image collecting unit, a sound collecting unit or an infrared collecting unit.

[0172] In another possible implementation, the processing unit is specifically configured to: receive the collected information sent by the collecting device, the collected information comprising the target information.
