[0040] Preferred embodiments of the present disclosure will be described in more detail with reference to the drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the structures and devices shown in the drawings are not necessarily drawn to scale. In addition, the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0041] The term "comprising" and variations thereof as used herein are intended to mean "including but not limited to". The term "or" as used herein is intended to mean "and / or". The term "based on" as used herein is intended to mean "based, at least in part, on". The terms "one example embodiment" and "an embodiment" as used herein are intended to mean "at least one example embodiment". The term "another embodiment" as used herein is intended to mean "at least one additional embodiment". The terms "first", "second", and the like as used herein can refer to different or identical objects. Other explicit or implicit definitions can also be included below.

[0042] As described above, in the conventional wrist-wearable device and its data interaction scheme, the conventional wrist-wearable device cannot perform real-time video data interaction with other communication devices, because the wrist-wearable device generally does not have a camera function, and the memory and data interaction manner of the wrist-wearable device are difficult to meet the higher requirements required for video data interaction.

[0043] To at least partially solve one or more of the above problems and other potential problems, example embodiments of the present disclosure propose a scheme of a wrist-wearable device. The wrist-wearable device includes a camera assembly including a camera that is pop-able or rotatable from an inside of a housing of the wrist-wearable device to an outside of the housing so as to capture video data, a control unit to generate an output signal after obtaining a receiving address of a server for pushing streaming media data that is generated based on the video data, a communication unit to transmit the streaming media data to the server based on the output signal, and a power supply unit to supply electric power to the camera, the control unit, and the communication unit.

[0044] In the above scheme, by pop-able or rotatable camera assembly to capture video data via the wrist-wearable device and obtaining a receiving address of a server to transmit streaming media data generated based on the captured video data, the present disclosure enables real-time video data interaction.

[0045] Figure 1 A schematic diagram of a system 100 for data interaction according to an embodiment of the present disclosure is schematically shown. As shown, the system 100 includes a wrist-wearable device 110, a terminal device 120, a streaming media server 130, a cloud server 150, and a file server 160. The wrist-wearable device 110, the terminal device 120, the streaming media server 130, and the cloud server 150 are connected via a network 140. Figure 1

[0046] ​Regarding the wrist-wearable device 110, in some embodiments, it can be a smart watch or a smart bracelet. The wrist-wearable device 110 is equipped with wireless transceiving capability and can access the Internet, it can directly communicate with the terminal device 120, and can also communicate with the cloud server 150 or the streaming server 130 for real-time interaction of audio data and video data. The wrist-wearable device 110 at least includes a camera 112, a control unit, a communication unit and a power supply unit. The camera 112 is used to collect video data. When no video data is collected, the camera can be stored inside or on the side of the shell of the wrist-wearable device 110, when video data is collected, the camera can be popped out or rotated out of the shell of the wrist-wearable device 110, or exposed outside the shell of the wrist-wearable device 110. The control unit is used to generate streaming data based on the video data obtained by the camera, and when it is determined that the wrist-wearable device 110 has obtained the receiving address of the server (such as a streaming server or a file server) for pushing the streaming data, an output signal is generated to control the communication unit to send the streaming data to the receiving address of the streaming server or the file server in real time. In some embodiments, the streaming data is generated based on the video data collected by the camera of the wrist-wearable device 110 and the audio data collected by the pick-up. The power supply unit is used to provide power for the camera, the control unit and the communication unit. The power supply unit, for example, includes a power management module, a battery and a charging interface. For example, the power provided by the power supply unit can come from a lithium battery built in the wrist-wearable device 110. The power management module and the charging interface perform power management and charging for the lithium battery. Regarding the wrist-wearable device 110, the following will be described in combination with Figures 2 to 5 The detailed description is not repeated here.

[0047] As to the terminal device 120, in some embodiments, it can be an electronic device with wireless transceiving capability and can access the Internet. The terminal device 120 is, for example but not limited to, a mobile phone, a smart phone, a laptop computer, a tablet computer, a personal digital assistant (PDA), a wearable smart device, and the like. The terminal device 120 can directly communicate with the wrist-wearable device 110, and can also interact with the cloud server 150, the streaming media server 130, and the file server 160 in real time for streaming media data. In some embodiments, the terminal device 120 at least includes a communication unit, a memory, and a processor. The communication unit is used to communicate with at least one of the cloud server 150, the streaming media server 130, the file server 160, and the wrist-wearable device 110. The memory is used to store one or more computer programs. The processor is coupled to the memory and executes the one or more programs to enable the terminal device 120 to browse the audio data and the video data collected by the wearable device 110 in real time. For example, the terminal device 120 can browse the video information taken by the wearable device 110 in real time. In addition, the terminal device 120 can also browse the video data taken by the wearable device 110 in the past (for example, but not limited to, at a certain time) and pushed to the server side (for example, the file server 160).

[0048] As to the cloud server 150, it is used to interact with at least one of the wrist-wearable device 110, the terminal device 120, the streaming media server 130, and the file server 160. In some embodiments, it can have one or more processing units, including special-purpose processing units such as GPU, FPGA, and ASIC, and general-purpose processing units such as CPU. In addition, one or more virtual machines can also run on the cloud server 150. The terminal device 120 and the wrist-wearable device 110 can respectively establish communication with the cloud server 150. For example, the cloud server 150 can provide the terminal device 120 with the receiving address of the streaming media server after establishing communication with the terminal device 120, so that the terminal device 120 can obtain the streaming media data (for example, video data) pushed by the wrist-wearable device 110 from the streaming media server. For another example, the cloud server 150 can send the wrist-wearable device 110 with the receiving address of the streaming media server 130 after establishing communication with the wearable device 110, so that the wearable device 110 can push its streaming media data to the receiving address of the streaming media server 130.

[0049] Regarding the streaming server 130, it is configured to transmit audio, video and multimedia files in a streaming manner (based on streaming protocols such as RTP / RTSP, MMS, RTMP, etc.) in the network. By pushing continuous audio and video data in the form of streaming data after compression onto the streaming server 130 and being stored thereon, a user can watch the audio and video data (e.g. via the terminal device 120) while downloading, without having to wait for the entire file to be downloaded. The streaming server 130 can receive the compressed real-time video stream captured by the wrist-wearable device 110 and live broadcast it to the user at the terminal device 120 side in a streaming protocol. The terminal device 120 can browse the video information captured by the wrist-wearable device 110 and pushed onto the streaming server 130 in real time. In some embodiments, the streaming server 130 can receive, transmit video in the MMS protocol and use Windows Media Player (WMP) as a front-end player. In addition, the streaming server 130 can support time shift and time-shifted video download functions. In some embodiments, the streaming server 130 can have one or more processing units, including special-purpose processing units such as GPUs, FPGAs and ASICs, and general-purpose processing units such as CPUs. In addition, one or more virtual machines can also run on the cloud server 150.

[0050] The file server 160 is configured to store the video data files captured and pushed by the wrist-wearable device 110, so as to share the video data files captured by the wrist-wearable device 110 with other users through the network. For example, the wrist-wearable device 110 can obtain the file receiving address of the file server 160 via the cloud server 150, for pushing the video data to the file receiving address of the file server 160. The terminal device 120 can obtain the file receiving address of the file server 160 via the cloud server 150, for obtaining the streaming data pushed by the wrist-wearable device 110 from the file receiving address by the terminal device 120. In some embodiments, the file server 160 can be a centralized file server, or a distributed file server extended based on a storage area network (SAN) and network-attached storage (NAS). In some embodiments, the file server 160 can have one or more processing units, including special-purpose processing units such as GPUs, FPGAs and ASICs, and general-purpose processing units such as CPUs. In addition, one or more virtual machines can also run on the file server 160.

The communication module 214 interacts with the control unit 212. The communication module 214 is used for data interaction between the wrist-worn wearable device 210 and the terminal device 260, and external servers (e.g., cloud servers, streaming media servers, and file servers). The display screen 226 (or touchscreen) is used to receive touch input from the user (e.g., audio volume adjustment input) and display relevant information. The wrist-worn wearable device 210 can also receive key input from the user via button 252. In some embodiments, the wrist-worn wearable device 210 also includes a pickup (microphone) for picking up the user's voice information. A power management module 224 is connected to a battery 242 for power management of the wrist-worn wearable device 210 and for providing charging power to the battery 242 via a charging interface 230. The wrist-worn wearable device 210 is also equipped with multiple sensors, including, but not limited to, a heart rate sensor 240, a gyroscope sensor 238, an accelerometer sensor 236, and a barometer sensor 234.

[0056] ​The camera pop-up assembly and locking device of the wrist-wearable device 300 are configured to cause the telescopic camera assembly 310 to pop out of the housing of the wrist-wearable device 300. The camera pop-up assembly, for example, includes at least a first elastic component (e.g., a first spring) that is elastically coupled to the camera assembly. The locking device is configured to: in a first position, cause the first elastic component to be in a compressed state so as to hold the camera inside the housing; and in a second position, cause the first elastic component to be in an extended state so as to pop the camera out of the housing. The following will be described in conjunction with Figure 4 The camera pop-up assembly and the locking device will be described in detail below.

[0057] Figure 4 A structural diagram of a wrist-wearable device 400 according to an embodiment of the present disclosure is shown. As shown, the wrist-wearable device 400 is in the form of a watch or a bracelet for convenience of discussion without loss of generality. Figure 4 The wrist-wearable device 400 can also be in other forms, which are not shown. Figure 4 The wrist-wearable device 400 can also be in other forms, which are not shown. Figure 4 The wrist-wearable device 400 can also be in other forms, which are not shown.

[0058] In some embodiments, the structures of the wrist-wearable device 400 related to the camera pop-up or retraction, for example, but not limited to, include: the housing 432 of the wrist-wearable device 400, the camera assembly 410, the camera pop-up assembly (e.g., including: a first elastic component, which further includes the spring 414 and the telescopic cover 412), the accommodating assembly 416 (e.g., a camera cover), the locking device 426 (e.g., a spring hook), a second elastic component 424 (e.g., including at least one spring), a connecting device (e.g., a screw 418, a nut 430), a button 420, etc.

[0059] Regarding the key 420, it is used to receive user's pressing input regarding the extension or retraction of the camera. In some embodiments, the key 420 is in contact with the locking device 426 via the second elastic component 424, for causing the locking device 426 to be at the second position (corresponding to the camera retracted position) when the key 420 is pressed. In some embodiments, the key 420, for example, comprises a first portion 421 mounted outside the housing 432 and a second portion 422 accommodated inside the housing 432. The second portion 422 is elastically coupled (or in elastic contact) with the second elastic component 424 in the longitudinal direction, for causing the second portion 422 to compress the second elastic component 424 when the user presses the key 420, which in turn causes the locking device 426 in elastic contact with the second elastic component 424 to move to the second position.

[0060] Regarding the second elastic component 424, it is in contact with the key and the locking device respectively, for causing the locking device 426 to be at the second position when the key 420 is pressed. The second elastic component 424 at least comprises a spring.

[0061] Regarding the locking device 426, it is used to cause the first elastic component 414 to be in the compressed state for locking the camera 410 in the housing 432 (e.g. the accommodating component 416) at the first position (e.g. corresponding to the camera retracted position). The locking device 426 is also used to cause the first elastic component to be in the extended state for retracting the camera 410 from the housing 432 (e.g. the accommodating component 416) at the second position (e.g. corresponding to the camera retracted position). In some embodiments, the locking device 426 comprises a second elastic component contact portion 425, a first elastic component coupling portion 427 (e.g. without limitation to a hook portion) and a support portion 428. The second elastic component contact portion 425 is, for example, an inclined surface. When the user presses the key 420, the second portion 422 of the key 420 moves towards the inside of the housing, causing the second elastic component 424 to compress, which in turn causes the second elastic component contact portion 425 to cause the locking device 426 to move to the second position, which in turn causes the first elastic component coupling portion 427 to decouple from the first elastic component 414, causing the first elastic component to be in the extended state. In some embodiments, the locking device 426 is a hook coupled with the first elastic component.

[0062] A first elastic component is configured to couple with the locking device 426 when the locking device 426 is in the first position, and decouple from the locking device 426 when the locking device 426 is in the second position. The first elastic component includes, for example, a spring 414 and a telescopic cover 412. The telescopic cover 412 includes, for example, a locking device coupling portion 413 and a spring contact portion 415. The spring 414 is in a compressed state when the locking device coupling portion 413 of the first elastic component is coupled with the locking device 426, and is in an expanded or stretched state when the locking device coupling portion 413 of the first elastic component is decoupled from the locking device 426. When the user presses the button 420, the locking device 426 moves to the second position, so that the first elastic component coupling portion 427 is decoupled from the locking device coupling portion 413 of the first elastic component. The spring 414 of the first elastic component is in an expanded or stretched state when it is decoupled from the locking device 426, and thus pushes the telescopic cover 412 and the camera assembly 410 away from the inside of the housing 432 under the elastic tension, so that the camera pops out or extends out of the housing 432 for collecting video information.

[0063] Regarding the telescopic cover 412, in some embodiments, in addition to the locking device coupling portion 413 and the spring contact portion 415 mentioned above, the telescopic cover 412 can further include a locking device guide slot 411. When the wrist-wearable device 400 completes the collection of video information, for example, the user presses the camera assembly 410, under the pressing force, the telescopic cover 412 in contact with the camera assembly 410 moves towards the inside of the housing, the spring 414 is compressed, so that the locking device coupling portion 413 moves to the inside of the first elastic component coupling portion 427 of the locking device 426, when the user no longer presses the camera assembly 410, the spring 414 expands, so that the locking device coupling portion 413 is coupled with the first elastic component coupling portion 427 (for example, a hook portion) of the locking device 426 contained in the guide slot 411, thereby locking the camera assembly 410 inside the housing 432.

[0064] Regarding the containing assembly 416, it is, for example, a camera cover for containing the camera assembly 410. In some embodiments, the containing assembly 416 includes a fixing portion 419, by which the camera cover can be fixed inside the housing 432. The containing assembly 416 can also fix one end of the spring 414, for example, through a screw 418, a nut 430 or the like.

[0065] Figure 5 A schematic diagram of the camera extension and retraction state in the wrist-wearable device 500 according to an embodiment of the present disclosure is shown. It should be understood that the wrist-wearable device 500 can also include constituent parts not shown and / or can omit the constituent parts shown, and the scope of the present disclosure is not limited in this respect.

[0066] Figure 5 The left part of FIG. 16 schematically shows the camera in the retracted state in the wrist-wearable device 500. When the camera is in the retracted state, the locking device 512 is in the first position, which is coupled with the first elastic component (not shown) in the accommodating assembly 416 to keep the camera assembly inside the shell. Figure 5 The right part of FIG. 16 schematically shows the camera in the extended state in the wrist-wearable device 500. At this time, the button 512 is pressed, and the locking device 512 is in the second position, which is decoupled with the first elastic component (not shown) in the accommodating assembly 416, so that the camera assembly is extended outside the shell.

[0067] The structure for extending and retracting the camera into the shell can also be implemented in other ways. For example, the wrist-wearable device 500 can be configured with a camera assembly holder and a self-locking device 3 to lock the camera assembly when the camera assembly extended out of the shell is pressed to a predetermined position (e.g., flush with the edge of the shell), and to pop the camera assembly out when the camera assembly is pressed again.

[0068] The wrist-wearable device 500 can also adopt other ways, such as a rotating assembly, to rotate the camera assembly turned into the shell outside the shell for collecting video information.

Figure 1 The method 600 for data interaction is described with the wrist-wearable device 110, the terminal device 120, the streaming server 130, the cloud server 150, and the file server 160 as specifically shown.

[0070] At block 602, at the wrist-wearable device 110, video data is acquired via the camera, which can be popped out or rotated out of the housing of the wearable device 110 from inside the housing. In some embodiments, the wrist-wearable device 110 initiates the camera to collect video information or data in response to determining that a trigger instruction to take a video is detected. In some embodiments, the wrist-wearable device 110 also initiates the pickup to collect audio data at the same time. In some embodiments, the wrist-wearable device 110 further detects whether a status indication signal that the camera has been successfully popped out or rotated out (or extended) of the housing is received in response to determining that a trigger instruction to take a video is detected. The status indication signal is emitted by a limit switch based on the position detection of the locking device, for example. By employing the above-mentioned means, it is not necessary to manually confirm whether the camera is in a position suitable for collecting video information. In addition, by enabling the camera to be popped out or rotated out of the housing of the wrist-wearable device from inside the housing when collecting video information, and to be rotated or retracted into the object when not collecting video information, not only is the camera protected from wear and tear or damage due to exposure, but also the wrist-wearable device is prevented from being triggered to take a video at an inappropriate time.

[0071] At block 604, it is determined whether the wrist-wearable device 210 has established communication with the cloud server 150. In some embodiments, the wrist-wearable device 210 further determines whether the wrist-wearable device 210 has established communication with the streaming server 130 in order to acquire a receiving address required for pushing streaming data.

[0072] At block 606, when the wrist-wearable device 210 determines that communication with the cloud server 150 has been established, the receiving address of the streaming server for pushing streaming data is acquired via the cloud server 150, the streaming data being generated based on the video data. In some embodiments, the wrist-wearable device 210 sends a request to the cloud server 150 to acquire the receiving address of the streaming server 130 for pushing video data; then the cloud server 150 acquires the receiving address of the streaming server 130. In some embodiments, when the wrist-wearable device 210 requests to push a real-time video data stream, the cloud server 150 determines a target streaming server suitable for receiving the video data stream among a plurality of streaming servers based on the status detection of the plurality of streaming servers and a load balancing strategy, in order to acquire the receiving address of the target streaming server with the smallest current load.

[0073] At block 608, the streaming media data is sent to the receiving address for the terminal device 120 associated with the wrist-wearable device 110 to acquire the video data in real time via the receiving address. In some embodiments, the wrist-wearable device 110 confirms whether the receiving address of the streaming media server 130 is acquired successfully; when confirming that the receiving address of the streaming media server 130 is acquired successfully, the wrist-wearable device 110 pushes the collected streaming media data to the receiving address of the streaming media server 130 in real time. In some embodiments, after the streaming media server 130 successfully receives the pushed video data, the wrist-wearable device 110 can receive an identifier indicating that the streaming media server successfully receives the video data. In some embodiments, the cloud server 150 provides the terminal device 120 with the receiving address of the streaming media server 130 for storing the real-time streaming media data pushed by the wrist-wearable device 110, so that the terminal device 120 acquires the real-time streaming media data (at least including video data) pushed by the wrist-wearable device 110 from the streaming media server 130 in real time.
