[0003] When elderly users read electronic products on the sofa, due to the deterioration of vision and the limitation of the display size of the electronic product display screen, they often need to wear reading glasses to see the display content on the electronic device clearly. In the related art, the method of setting a display screen on the smart sofa is often adopted to meet the entertainment needs of users, but this cannot solve the reading difficulty problem of elderly users, and the intelligence level of smart sofas is still low. Summary of the invention

[0004] The embodiments of the present application disclose a screen projection method based on a smart sofa and related products, which optimize the reading experience of elderly users on electronic products when resting on the sofa and improve the intelligence level of the smart sofa.

[0005] The embodiment of the present application discloses a screen projection method based on a smart sofa, which is used for a smart sofa. The smart sofa includes an adjustable backrest, an adjustable footrest, a seat cushion and an armrest. The seat cushion is provided with a pressure sensor. The armrest is provided with a projector. The armrest includes a hand placement surface, a first side surface, a second side surface and a front side surface. The first side surface is respectively connected to the hand placement surface and the upper surface of the seat cushion. The second side surface is symmetrically arranged with the first side surface. The front side surface is respectively connected to the hand placement surface, the first side surface and the second side surface. A first projection port is provided on the front side surface. The projector projects through the first projection port. The method includes:

[0006] When a user is detected by the pressure sensor, obtaining a current pressure value of the pressure sensor;

[0007] When the current pressure value is greater than a preset pressure value, establishing a communication connection with a target electronic device of the user;

[0008] Acquiring display content of the target electronic device through the communication connection;

[0009] The display content is projected by the projector to a position in front of the smart sofa via the first projection port.

[0010] In the above technical solution, the smart sofa establishes a communication connection with the user's target electronic device and projects the display content of the target electronic device onto a distant wall or screen, thereby making the display content larger and solving the problem that the elderly cannot see nearby objects clearly. It optimizes the reading experience of the elderly users for the display content of the electronic device and improves the intelligence level of the smart sofa.

[0011] In a possible implementation, the smart sofa further includes a camera, and when the current pressure value is greater than a preset pressure value, before establishing a communication connection with the target electronic device of the user, the method further includes:

[0012] Controlling the camera to be in an on state;

[0013] Acquire a target image including the user through the camera;

[0014] Image recognition is performed on the target image, and when it is recognized that the user is holding an electronic device, the electronic device held by the user is determined as the target electronic device.

[0015] In the above technical solution, the image recognition function of the camera is used to automatically determine the electronic device that the user is holding, reducing the steps for the user to manually select the target device, improving convenience, and ensuring that the user does not need to manually specify the electronic device. The system can accurately identify and avoid incorrect connections or delays. Through automatic identification, the interaction between the user and the smart sofa is smoother and more natural, enhancing the intelligence of the device and the user experience.

[0016] In a possible implementation manner, when the current pressure value is greater than a preset pressure value, before establishing a communication connection with the target electronic device of the user, the method further includes:

[0019] Acquire the distance between each electronic device in the at least one electronic device and the smart sofa according to the positioning information in the at least one first feedback signal;

[0020] The electronic device corresponding to the minimum distance is determined to be the target electronic device.

[0021] In the above technical solution, by sending and feedback of detection signals, the smart sofa can quickly find the nearest electronic device as the screen projection target among multiple devices, avoiding the complicated process of manual selection by the user. The user only needs to sit down, and the system can automatically detect the nearest electronic device for connection, reducing unnecessary operation steps. The system will only select the closest electronic device, reducing interference with other electronic devices in the environment, and improving the accuracy and operating efficiency of the system.

[0022] In a possible implementation, the smart sofa further includes a memory, in which historical identification information of historical electronic devices that have established connections with the smart sofa is pre-stored. When the current pressure value is greater than a preset pressure value, before establishing a communication connection with the target electronic device of the user, the method further includes:

[0023] sending a second detection signal;

[0024] Receiving at least one second feedback signal sent by at least one electronic device in the environment where the smart sofa is located in response to the second detection signal, each second feedback signal includes identification information of a corresponding electronic device;

[0025] When the target identification information in the identification information of at least one electronic device corresponding to the at least one second feedback signal is the same as one of the historical identification information, the electronic device corresponding to the target identification information is determined as the target electronic device.

[0026] In the above technical solution, through the use of historical records, the system can quickly match the user's commonly used electronic devices, improve the connection speed, and there is no need to reselect electronic devices each time a connection is made. The system can automatically identify commonly used electronic devices and provide users with more personalized services. The automatic matching of smart sofas with commonly used devices reduces the possibility of incorrect connections and increases the accuracy and efficiency of connections.

[0027] In a possible implementation, the smart sofa and the target electronic device are both devices in a smart home system, the smart home system further includes a central control device, and establishing a communication connection with the target electronic device of the user includes:

[0028] The smart sofa sends a connection request message to the central control device, wherein the connection request message includes identification information of the target electronic device;

[0029] The central control device sends a connection information acquisition request to the target electronic device according to the connection request information;

[0030] After receiving the connection information acquisition request, the target electronic device sends the target connection information to the central control device;

[0031] After receiving the target connection information, the central control device sends the target connection information to the smart sofa;

[0032] After receiving the target connection information, the smart sofa establishes a communication connection with the target electronic device according to the target connection information.

[0033] In the above technical solution, the communication connection process between the smart sofa and the target electronic device is simplified through the intermediary role of the smart home central control device, making the device interaction smoother. The smart sofa and the target electronic device are coordinated through the central control device, which enhances the integration and coordination between smart home devices. The connection management is performed through the central control device to ensure that the communication process is more stable and the security is also improved.

[0034] In a possible implementation, the hand placement surface is provided with a control panel and a second projection port, the projector is rotatably provided in the armrest, and the method further includes:

[0035] receiving a control instruction through the control panel, and adjusting the inclination angle of the backrest and / or the footrest according to the control instruction;

[0036] determining the current posture of the user according to the inclination angle of the backrest and / or the footrest;

[0037] When the current posture is a posture in which the angle between the plane where the user's body is located and the horizontal plane is smaller than a preset angle, the projection angle of the projector is adjusted to correspond to the second projection port, and the display content is projected by the projector through the second projection port to a position above the smart sofa.

[0038] In the above technical solution, in addition to wireless connection, users can also connect devices through physical connection methods such as data cables. A variety of connection methods are provided to meet the needs of different scenarios. By displaying prompt information on the projector, users can clearly understand how to make a physical connection, reducing the difficulty of operation. At the same time, physical connections are usually more stable than wireless connections, ensuring a smoother projection process.

[0060] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0061] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish the same items or similar items with substantially the same functions and effects. For example, the first instruction and the second instruction are to distinguish different user instructions, and their order is not limited. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit them to be different.

[0062] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0063] In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0064] In addition, the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products, or devices.

[0065] When people are young, the lens of the eye is highly flexible and elastic, and can quickly adjust to different viewing distances. When people need to see close objects, the lens will thicken to enhance its refractive power. However, as people age, the lens will gradually harden and lose its elasticity, and it cannot be easily deformed as when they were young, causing close objects to become blurred. The eye's adjustment range gradually narrows, and it is difficult to quickly adjust the focus from far to near objects. This phenomenon is more obvious in low light or fatigue conditions. At the same time, with age, other structures of the eyeball, such as the cornea and retina, may also undergo aging changes, affecting the refraction of light and the clarity of retinal imaging. These changes will also aggravate the symptoms of decreased near vision. Presbyopia in the elderly requires them to wear reading glasses or enlarge the font when looking at electronic devices at close range, otherwise the text will be blurred. At the same time, eye diseases such as cataracts, glaucoma or macular degeneration in the elderly require more light and higher contrast when reading screens. The reflection or strong light of electronic devices makes the elderly feel uncomfortable when reading, especially in strong light or dim light environments, and they are prone to fatigue.

[0066] Smart sofas are a type of furniture that combines modern technology with traditional sofa design. They provide a comfortable seating experience while integrating intelligent control and functional expansion, such as intelligent adjustment, health monitoring, and multimedia entertainment. Smart sofas are becoming increasingly popular in home environments, especially in smart home systems, where they can provide users with a more personalized and convenient user experience. Smart sofas are equipped with electric control systems. Users can adjust the angles of the sofa's backrest, footrest, headrest, and other parts through remote controls or mobile phone applications to ensure the comfort of different sitting or lying positions. Some high-end smart sofas can even automatically adjust according to the user's body shape and posture. Many smart sofas integrate massage functions, including full-body massage and local massage modes. The massage function relieves the user's physical fatigue and muscle soreness through devices such as airbags and vibrators, making the sofa not only have a rest function, but also provide health management similar to a massage chair. Smart sofas are equipped with wireless connection functions such as Bluetooth and Wi-Fi, and can be synchronized with electronic devices such as TVs, speakers, and projectors to create a multimedia entertainment center. Some smart sofas come with a speaker system, and users can remotely control them through mobile phones or tablets to enjoy a home theater-like experience. Smart sofas usually support voice control, APP remote control, and other methods. Users can issue commands through voice assistants to adjust the sofa angle, start massage mode or control other smart home devices connected to the sofa. Smart sofas are equipped with pressure sensors, body temperature sensors, etc., which can monitor the user's sitting posture, pressure changes and other health data. Based on these data, the sofa will prompt the user to adjust the posture, rest or do simple healthy exercises in a timely manner to reduce the health problems caused by long-term bad sitting posture. Smart sofas often integrate wireless charging modules or USB interfaces, which are convenient for users to charge mobile phones, tablets and other devices while resting. At the same time, sofas can establish data connections with these electronic devices to provide more convenient synchronization services, such as playing videos and music. Some smart sofas have a memory function that can record the user's favorite settings, such as commonly used sofa angles, massage modes, etc. Users can quickly return to their most comfortable state through buttons or voice commands. Smart sofas are not just a seat for rest. They combine a variety of intelligent functions with modern technology to greatly enrich the experience of family life. In daily life, smart sofas can not only provide comfortable leisure and entertainment functions, but also provide support for users' health and convenience through health management, intelligent control and other methods, becoming an important part of the modern smart home system.

[0067] Traditional smart sofas often use the method of enlarging the display screen to enhance the reading experience of elderly users, but in essence the distance between the enlarged display screen and the elderly users is still relatively close, so that even if the displayed content is enlarged, the elderly users still cannot fully see the displayed content on the display screen. Due to the close distance, when the elderly users use the enlarged display screen for a period of time, they are prone to visual fatigue.

[0068] The embodiment of the present application establishes a communication connection with a target electronic device used by an elderly user, and projects the display content on the target electronic device through a projector provided on the smart sofa to a distant wall or screen for enlarged display, thereby optimizing the reading experience of the elderly user on the electronic device when resting on the smart sofa and improving the intelligence level of the smart sofa.

[0069] In order to implement the method described above, the application scenario of the embodiment of the present application is first introduced to understand the functions of the smart sofa.

[0070] like Figure 1 As shown, an application scenario diagram 100 for realizing screen projection based on a smart sofa provided in an embodiment of the present application, the application scenario diagram includes a smart sofa 101, a seat cushion 102, a pressure sensor 103, an armrest 104, a projector 105, a backrest 106, a footrest 107, a user 108, an electronic device 109 and a screen 110.

[0071] In some possible embodiments, the smart sofa 101 is usually made of solid metal or solid wood to provide stable support. The design of the frame takes into account the movement space of movable parts such as the adjustable backrest 106 and the footrest 107. The backrest 106, the seat cushion 102 and the footrest 107 are the core parts that affect the comfort. The use of materials such as high-density sponge or memory foam can ensure the comfort of users sitting and lying for a long time. The smart sofa 101 usually embeds an electric adjustment device in the backrest 106, the seat cushion 102 and the footrest 107, and the angle and hardness can be adjusted according to the needs of the user 108. The armrest 104 is composed of a hand placement surface located on the upper surface, a first side surface, a second side surface and a front side surface. The first side surface of the armrest 104 is respectively connected to the hand placement surface located on the upper surface and the upper surface of the seat cushion 102, the second side surface is symmetrically arranged with the first side surface, and the front side surface is connected with the hand placement surface, the first side surface and the second side surface located on the upper surface. The surface material of the armrest 104 may include but is not limited to genuine leather, artificial leather, fabric, environmentally friendly cotton, etc., and the lining material of the armrest 104 may be sponge, memory foam or foam filler. At the same time, the surface of the armrest 104 may be treated with waterproof and antifouling treatment and antibacterial treatment to prevent beverages or other liquids from penetrating into the interior after being spilled, reduce stains and reduce bacterial growth, and is suitable for use by the elderly or children.

[0072] In some possible embodiments, a pressure sensor 103 is provided in the cushion 102 of the smart sofa 101. The pressure sensor 103 is one of the important components in the smart sofa and is mainly used to detect whether the user 108 sits down, stands up or the center of gravity of the body changes, thereby triggering related functions. The pressure sensor in the smart sofa helps to realize automated operations, such as automatically adjusting the angle of the sofa, activating the massage function, starting the projection, etc. By detecting the weight or pressure changes of the user 108, the pressure sensor 103 can sense whether the user sits down or stands up, and start or shut down other functions of the sofa, such as projection, speakers or heating systems, etc. The pressure sensor 103 can adjust the functions of the smart sofa according to the weight or pressure of the user, such as massage intensity, backrest angle, etc. According to the distribution of pressure, the pressure sensor 103 can be used to determine whether the user's sitting or lying posture is reasonable, and cooperate with the automatic adjustment function of the sofa to provide the best comfort. When the pressure sensor 103 detects that the user has been away for a long time, the smart sofa can automatically enter the standby state to save energy. The types of pressure sensors may include but are not limited to resistive pressure sensors, capacitive pressure sensors, piezoelectric sensors, and fiber optic pressure sensors. The pressure sensor 103 may also be arranged in the backrest 106 and the footrest 107. The pressure sensor 103 arranged in the backrest 106 can be used to detect whether the user 108 is leaning on the sofa, and cooperate with the sensor in the seat cushion 102 to accurately judge the posture of the user 108. The pressure sensor 103 arranged in the footrest 107 can be used to detect whether the legs of the user 108 are placed on the footrest 107, thereby controlling the extension or angle adjustment of the footrest 107.

[0073] In some possible embodiments, the adjustment of the backrest 106 and the footrest 107 of the smart sofa 101 mainly depends on the motor drive, and the motor drives the transmission mechanism such as gears, chains or hydraulic devices to achieve adjustment at different angles. The backrest 106 is connected to the mechanical structure through the motor. After the user 108 issues an adjustment command, the motor drives the gear or sliding structure to tilt the backrest 106 forward and backward. The power of the motor accurately controls the angle of the backrest 106, which can usually be adjusted to a variety of different tilt positions to adapt to sitting or lying. The adjustment of the footrest 107 is also achieved by the motor. The motor drives the footrest 107 to rise or fall and adjust to a suitable position to meet the user's foot support needs. The footrest 107 of some smart sofas 101 can automatically adjust to the optimal length or height according to the height of the user 108.

[0074] In some possible embodiments, a projection port is provided on the front side of the armrest 104, and a projector 105 is provided inside the armrest 104, and the projector can project the projection content onto the screen 110 through the projection port. The core principle of the projector 105 is to magnify the display content of the electronic device 109 and project it onto the surface of the screen 110 through the internal light source, lens system and image processing chip. The projector 105 in the smart sofa 101 is usually designed in miniature to adapt to the sofa structure and is equipped with an automatic adjustment function to ensure clear picture projection. The projector 105 usually uses LED or laser as a light source. These light sources have a long service life and low power consumption, and are suitable for being embedded in household appliances such as the smart sofa 101. The projector 105 generally uses digital light processing or liquid crystal display technology to process images. The digital light processing projector 105 processes light through tiny reflective lenses, while the liquid crystal display technology generates images through a liquid crystal display panel. The screen 110 is used to receive the projection image of the projector 105 . The types of the screen 110 may include but are not limited to a white screen, a gray screen, a reflective screen, an electric screen, and the like.

[0075] In some possible embodiments, when the elderly user 108 rests on the smart sofa 101 and uses the electronic device 109, due to the deterioration of vision and the size limitation of the display screen of the electronic device 109, it is necessary to project the display content of the electronic device 109 onto the screen 110 to achieve better reading and viewing effects. The electronic device 109 may include but is not limited to smart phones, desktop computers, tablet computers, laptops, smart speakers, digital assistants, augmented reality (AR) / virtual reality (VR) devices, smart wearable devices and other electronic devices, and the operating system running on the electronic device 109 may include but is not limited to Android system, IOS system, Linux, Windows, Unix and the like. The projector 105 of the smart sofa 101 can establish a communication connection with the electronic device 109 through the central control device, and the user 108 can directly project the content of the smart phone, tablet computer and other devices onto the wall or the screen 110 through a wireless connection, including videos, pictures, games and the like.

[0076] The above introduction to the application scenarios of the smart sofa can facilitate understanding of how the smart sofa works and implement the methods related to the embodiments of the present application. On this basis, the screen projection method based on the smart sofa is further introduced.

[0077] like Figure 2 As shown, it is a schematic flowchart 200 of a screen projection method based on a smart sofa provided in an embodiment of the present application, and the method comprises the following steps:

[0078] S201 : When a user is detected by the pressure sensor, obtain a current pressure value of the pressure sensor.

[0079] In some possible embodiments, the pressure sensor can convert the pressure signal applied to the seat cushion by the user on the smart sofa into an electrical signal, and judge the size of the pressure value borne by the seat cushion according to the size of the electrical signal. The memory of the smart sofa stores the pressure values ​​of historical users. The smart sofa can judge whether the person on the seat cushion is a user or other object by comparing the pressure value collected by the current pressure sensor with the historical pressure values.

[0080] S202: When the current pressure value is greater than a preset pressure value, establish a communication connection with a target electronic device of the user.

[0081] In some possible embodiments, when the smart sofa obtains the pressure value collected by the pressure sensor and determines that the pressure value is greater than or equal to the preset pressure value, the smart sofa determines that the user is using the smart sofa at this time, and the smart sofa will turn on the camera to capture the user image through the camera. The smart sofa recognizes and analyzes the captured image and determines whether the captured image includes an electronic device. If the captured image includes the target electronic device, the smart sofa establishes a communication connection with the target electronic device through the central control device.

[0082] In some possible embodiments, when the smart sofa obtains the pressure value collected by the pressure sensor and determines that the pressure value is greater than or equal to the preset pressure value, the smart sofa determines that the user is using the smart sofa at this time, and the smart sofa will emit a detection signal to the surrounding environment. The electronic devices in the surrounding environment will return a feedback signal to the smart sofa, and the feedback signal includes the positioning information of each electronic device in the surrounding environment. The smart sofa calculates the distance from each electronic device in the environment to the smart sofa based on the positioning information, determines that the electronic device with the shortest distance is the target electronic device, and the smart sofa establishes a communication connection with the target electronic device through the central control device.

[0083] In some possible embodiments, when the smart sofa obtains the pressure value collected by the pressure sensor and determines that the pressure value is greater than or equal to the preset pressure value, the smart sofa determines that the user is using the smart sofa at this time, and the smart sofa will emit a detection signal to the surrounding environment. The electronic devices in the surrounding environment will return a feedback signal to the smart sofa, and the feedback signal includes the identification information of the electronic devices in the surrounding environment of the smart sofa. The smart sofa matches the identification information of the electronic devices in the surrounding environment with the historical identification information pre-stored in the memory. The smart sofa determines the electronic device with the same identification information as the historical identification information as the target electronic device, and establishes a communication connection with the target electronic device through the central control device.

[0084] In some possible embodiments, when a user uses a smart sofa, the armrest side of the smart sofa will open and expose a accommodating cavity, in which a data transmission module is provided. The user physically connects the electronic device used with the data transmission module on the armrest side of the smart sofa to realize communication transmission, and the smart sofa determines that the electronic device connected to the data transmission module is the target electronic device.

[0085] S203: Acquire display content of the target electronic device through the communication connection.

[0086] In some possible embodiments, the smart sofa establishes a wireless connection with the target electronic device through the central control device. The target electronic device sends the display content on the current display screen to the smart sofa by wireless transmission. The smart sofa receives the data sent by the target electronic device and obtains the display content on the display screen of the target electronic device.

[0087] In some possible embodiments, the smart sofa establishes a physical connection with the target electronic device through a data transmission module, and the target electronic device sends the display content on the current display screen directly to the smart sofa through the data transmission module. The smart sofa receives the data sent by the target electronic device and obtains the display content on the display screen of the target electronic device.

[0088] S204: Projecting the display content via the first projection port to a position in front of the smart sofa by the projector.

[0089] In some possible embodiments, when the smart sofa detects that the user is in a normal sitting position, the smart sofa controls the projector to project the display content on the target electronic device onto a distant screen or wall through the first projection port on the front side of the armrest.

[0090] In some possible embodiments, when the smart sofa detects that the user is in a lying position, the smart sofa controls and adjusts the lens angle of the projector to align it with the second projection port on the hand placement surface on the upper surface of the armrest of the smart sofa, and then controls the projector to project the display content on the target electronic device through the second projection port on the hand placement surface on the upper surface of the armrest to a distant screen or wall.

[0091] The above embodiment demonstrates a screen projection method based on a smart sofa, which optimizes the reading experience of elderly users on the target electronic device by projecting the display content of the target electronic device to a distant wall or receiving screen, thereby improving the intelligence of the smart sofa. Next, we will further introduce how the smart sofa identifies and establishes a connection with the target electronic device.

[0092] like Figure 3 As shown, it is a schematic flowchart 300 of a method for projecting a screen of an electronic device provided in an embodiment of the present application, and the method includes:

[0093] S301, the smart sofa obtains the pressure value detected by the pressure sensor.

[0094] In some possible embodiments, a pressure sensor built into the seat cushion of the smart sofa continuously monitors the seat cushion pressure of the user, and the sensor reads the pressure value in real time and sends the data to the control unit of the smart sofa.

[0095] S302, when the pressure value is greater than a preset pressure value, the smart sofa controls the camera to be turned on.

[0096] In some possible embodiments, the pressure value corresponding to the user's standard weight is pre-stored in the memory of the smart sofa. When the control unit of the smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value, the smart sofa determines that the user is using the smart sofa, and the control unit of the smart sofa controls the camera on the smart sofa to turn on and take an image of the user to further determine the electronic device that the target is using; when the control unit of the smart sofa determines that the pressure value detected by the pressure sensor is less than the preset pressure value, the smart sofa determines that other objects may be placed on the seat cushion of the smart sofa, and the camera is still in standby mode.

[0097] S303, the smart sofa obtains a target image through a camera.

[0098] In some possible embodiments, the camera starts to capture and process images in the environment, and transmits the captured images to the image processing unit of the smart sofa in real time.

[0099] S304, the smart sofa identifies the target electronic device included in the target image and the corresponding device type.

[0100] In some possible embodiments, the image processing unit of the smart sofa applies an image recognition algorithm to identify the device type corresponding to the electronic device appearing in the image, and the smart sofa determines that the electronic device appearing in the image is a target electronic device, where the device type may include but is not limited to smart phones, tablet computers, laptops, and smart wearable devices.

[0101] S305, the smart sofa sends a connection request message to the central control device, where the connection request message includes the type of electronic device.

[0102] In some possible embodiments, the control unit of the smart sofa constructs a connection request message including the device type and its identification information according to the identification result, and sends it to the central control device.

[0103] S306: The central control device sends a connection information acquisition request to the target electronic device according to the connection request information.

[0104] In some possible embodiments, after the central control device receives the connection request information sent by the smart sofa, it parses the request information, obtains the device type of the electronic device with which the smart sofa wants to establish a communication connection, queries the device that has already established a communication connection with the central control device, and sends a connection information acquisition request to the target electronic device corresponding to the device type obtained by the analysis.

[0105] S307: The target electronic device receives the connection information acquisition request and sends the target connection information to the central control device.

[0106] In some possible embodiments, after receiving the connection request, the target device performs identity authentication and sends target connection information to the central control device.

[0107] S308, after receiving the target connection information, the central control device sends the target connection information to the smart sofa.

[0108] In some possible embodiments, after receiving the connection information of the target electronic device, the central control device forwards it to the control unit of the smart sofa.

[0109] S309, after receiving the target connection information, the smart sofa establishes a communication connection with the target electronic device according to the target connection information.

[0110] In some possible embodiments, after receiving the connection information of the target electronic device, the smart sofa attempts to establish a network communication connection with the target electronic device for transmitting data.

[0111] S310, the smart sofa obtains display content of the target electronic device.

[0112] In some possible embodiments, after the smart sofa successfully establishes a communication connection with the target electronic device, the smart sofa requests the display content of the target device and obtains the image information, text information, audio information, etc. of the target electronic device. The target electronic device transmits the image information, text information, audio information, etc. requested by the smart sofa to the smart sofa.

[0113] S311, the smart sofa projects the display content of the target electronic device through a projector.

[0114] In some possible embodiments, after the smart sofa acquires the display content of the target electronic device, the smart sofa detects the inclination angles of the backrest and the footrest, and determines the user's posture according to the inclination angles of the backrest and the footrest. When the smart sofa detects that the inclination angles of the backrest and the footrest are both less than a preset angle, the smart sofa determines that the user who is using the smart sofa is in a lying position, and the smart sofa controls and adjusts the lens angle of the projector to align it with the second projection port on the hand placement surface on the upper surface of the armrest, and the smart sofa uses the projector to project the display content of the target electronic device to the ceiling through the second projection port.

[0115] In some possible embodiments, after the smart sofa acquires the display content of the target electronic device, the smart sofa detects the inclination angles of the backrest and the footrest, and determines the user's posture according to the inclination angles of the backrest and the footrest. When the smart sofa detects that the inclination angles of the backrest and the footrest are both greater than or equal to the preset angle, the smart sofa determines that the user who is using the smart sofa is in a sitting position, and the smart sofa uses a projector to project the display content of the target electronic device to the wall or curtain in front of the smart sofa through the first projection port.

[0116] For example, the pressure sensor located in the seat cushion detects a pressure value of 700N, and the pressure value pre-stored in the smart sofa memory is 600N. The smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value. At this time, the smart sofa determines that the user is using the smart sofa, controls the camera to turn on, and the camera captures the user image and sends it to the image processing unit. The image processing unit recognizes that the user image includes a smart phone, an electronic device. The smart sofa determines that the smart phone is the target electronic device and sends a connection request message to the smart home central controller. The connection request message includes the device type information of the smart phone. After the smart home central controller receives the connection request message sent by the smart sofa, it checks whether the electronic devices that have established a wireless connection with the smart home central controller include the device type of the smart phone. If there happens to be a smart phone that has established a wireless connection with the smart home central controller, the smart home central controller determines that the smart phone is the target electronic device and sends a connection information acquisition request to the smart phone. After receiving the connection information acquisition request sent by the central control device, the smart phone verifies the identity of the smart home central control. After the identity verification is passed, the target connection information with the smart sofa is sent to the smart home central control. After receiving the target connection information sent by the smart phone, the smart home central control forwards the target connection information to the smart sofa. After receiving the target connection information of the smart phone, the smart sofa establishes a communication connection with the smart phone. The smart phone sends the image information, audio information, text information, etc. of the current display page to the smart sofa in a wireless transmission manner. At this time, the smart sofa detects that the inclination angle of the backrest is 60° and the inclination angle of the footrest is 45°. The preset angle in the memory of the smart sofa is 30°. The smart sofa detects that the inclination angle of the backrest and the inclination angle of the footrest are both greater than the preset angle. The smart sofa determines that the user who is using the smart sofa is in a sitting position. Then the smart sofa projects the image information of the smart phone through the first projection port on the front side of the armrest through the projector to the wall or screen in front of the smart sofa. At the same time, the smart sofa is also provided with a smart speaker, which is used to play the audio information of the smart phone synchronously when the projector projects the image information and audio information on the smart phone.

[0117] The above embodiments show how to determine the target electronic device through the camera. Through image recognition, the target device can be accurately identified and confirmed, reducing the risk of misidentification and improving the user experience. The smart sofa can achieve wireless connection with the target electronic device through the central control device, which is conducive to more intelligent home control and management. Next, how to determine the target electronic device through the positioning information of the electronic device is further introduced.

[0118] like Figure 4 As shown, it is a schematic flowchart 400 of another electronic device screen projection method provided in an embodiment of the present application, and the method includes:

[0119] S401, the smart sofa obtains the pressure value detected by the pressure sensor.

[0120] Step S401 is similar to step S301 and will not be described again here.

[0121] S402: When the pressure value is greater than a preset pressure value, the smart sofa sends a first detection signal to the surrounding environment.

[0122] In some possible embodiments, the pressure value corresponding to the user's standard weight is pre-stored in the memory of the smart sofa. When the control unit of the smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value, the smart sofa determines that the user is using the smart sofa, and the smart sofa transmits a broadcast signal to the surrounding environment to find nearby electronic devices.

[0123] S403, the smart sofa receives a feedback signal from the electronic device in response to the first detection signal, where the feedback signal includes positioning information of the electronic device.

[0124] In some possible embodiments, the smart sofa continuously monitors feedback signals returned by electronic devices in the surrounding environment in response to broadcast signals, and the feedback signals include positioning information of the electronic devices, which is used to indicate the position of the electronic devices relative to the smart sofa.

[0125] S404: The smart sofa calculates the distance between the electronic device and the smart sofa according to the positioning information included in the feedback signal.

[0126] In some possible embodiments, the smart sofa calculates the distance between each electronic device and itself based on the positioning information such as coordinate information in the feedback signal of the electronic device and its own positioning information, and obtains the distance between each electronic device and the smart sofa.

[0127] S405: The smart sofa determines that the electronic device corresponding to the minimum distance is the target electronic device.

[0128] In some possible embodiments, the smart sofa traverses the above distances to obtain the minimum distance, and determines that the electronic device corresponding to the minimum distance is the target electronic device. When the electronic device is closest to the smart sofa, it indicates that the electronic device is most likely the target electronic device being used by the user located above the cushion.

[0129] S406, the smart sofa sends a connection request message to the central control device, where the connection request message includes the location information of the target electronic device.

[0130] In some possible embodiments, the smart sofa constructs a connection request message, the connection request message includes the location information of the target electronic device, and the smart sofa sends the connection request message to the central control device.

[0131] S407: The central control device sends a connection information acquisition request to the target electronic device according to the connection request information.

[0132] In some possible embodiments, the central control device queries the positioning information of the electronic device that has established a wireless connection with the central control device based on the positioning information of the target electronic device, determines that the electronic device corresponding to the positioning information that is the same as the positioning information sent by the smart sofa is the target electronic device, and sends a connection information acquisition request to the target electronic device.

[0133] S408: The target electronic device receives the connection information acquisition request and sends the target connection information to the central control device.

[0134] S409, after receiving the target connection information, the central control device sends the target connection information to the smart sofa.

[0135] S410, after receiving the target connection information, the smart sofa establishes a communication connection with the target electronic device according to the target connection information.

[0136] S411, the smart sofa obtains display content of the target electronic device.

[0137] S412, the smart sofa projects the display content of the target electronic device through a projector.

[0138] Steps S408-S412 are similar to steps S307-S311 and are not described again here.

[0139] Exemplarily, the pressure sensor located in the seat cushion detects a pressure value of 750N, and the pressure value pre-stored in the smart sofa memory is 600N. The smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value. At this time, the smart sofa determines that the user is using the smart sofa, and the smart sofa sends broadcast information to the surrounding environment. After receiving the broadcast information, the smart phones and tablet computers in the surrounding environment return their own positioning information. The smart sofa calculates that the distance between the smart sofa and the smart sofa is 5m, and the distance between the tablet computer and the smart sofa is 0.3m based on the positioning information of the smart phone and the tablet computer and its own positioning information. The smart sofa determines that the tablet computer is the target electronic device, that is, the user located above the seat cushion is using the tablet computer. The smart sofa sends a connection request message to the smart home central controller, and the connection request message includes the positioning information of the tablet computer. After receiving the connection request message sent by the smart sofa, the smart home central controller checks whether the electronic devices that have established a wireless connection with the smart home central controller include the same positioning information as the positioning information sent by the smart sofa. If the tablet computer has established a wireless connection with the smart home central controller in advance, the smart home central controller can determine that the tablet computer is the target electronic device and send a connection information acquisition request to the tablet computer. After receiving the connection information acquisition request sent by the central control device, the tablet computer verifies the identity of the smart home central controller. After the identity verification is passed, the target connection information with the smart sofa is sent to the smart home central controller. After receiving the target connection information sent by the tablet computer, the smart home central controller forwards the target connection information to the smart sofa. After receiving the target connection information from the tablet computer, the smart sofa establishes a communication connection with the tablet computer. The tablet computer sends the image information, audio information, text information, etc. of the currently displayed page to the smart sofa by wireless transmission. The smart sofa detects at this time that the inclination angle of the backrest is 25° and the inclination angle of the footrest is 15°. The preset angle in the memory of the smart sofa is 30°. The smart sofa detects that the inclination angle of the backrest and the inclination angle of the footrest are both less than the preset angle. The smart sofa determines that the user who is using the smart sofa is in a lying position, then the smart sofa adjusts the lens of the projector to align with the second projection port on the hand placement surface on the upper surface of the armrest. The smart sofa projects the image information of the tablet computer onto the wall or screen in front of the smart sofa through the second projection port on the hand placement surface on the upper surface of the armrest. At the same time, a smart speaker is also provided on the smart sofa, which is used to synchronously play the audio information of the tablet computer when the projector is projecting the image information and audio information on the tablet computer.

[0140] The above embodiment shows that the smart sofa calculates the distance between the electronic device and the smart sofa by receiving the positioning information of the electronic device, and determines that the electronic device with the shortest distance is the target electronic device, which further improves the accuracy of the target electronic device identification. Next, how to identify the target electronic device through the identification information of the electronic device is further introduced.

[0141] like Figure 5 As shown, it is a schematic flowchart 500 of another electronic device screen projection method provided in an embodiment of the present application, and the method includes:

[0142] S501, the smart sofa obtains the pressure value detected by the pressure sensor.

[0143] Step S501 is similar to step S301 and will not be described again here.

[0144] S502: When the pressure value is greater than a preset pressure value, the smart sofa sends a second detection signal to the surrounding environment.

[0145] Step S502 is similar to step S402 and will not be described again.

[0146] S503: The smart sofa receives a feedback signal from the electronic device in response to the second detection signal, where the feedback signal includes identification information of the electronic device.

[0147] In some possible embodiments, the smart sofa will continuously monitor the feedback signal returned by electronic devices in the surrounding environment in response to the broadcast signal. The feedback signal includes the device ID information of the electronic device, that is, the unique identification code of the electronic device, which is used to indicate the identity of the electronic device.

[0148] S504: The smart sofa determines that the electronic device corresponding to the identification information included in the feedback signal that is the same as the preset historical identification information is the target electronic device.

[0149] In some possible embodiments, the memory of the smart sofa stores historical identification information of electronic devices that frequently communicate with the smart sofa. The smart sofa compares the identification information included in the feedback signal of the electronic device in the surrounding environment in response to the second detection signal with the pre-stored historical identification information, and determines that the electronic device in the surrounding environment corresponding to the identification information identical to the historical identification information is the target electronic device.

[0150] S505, the smart sofa sends a connection request message to the central control device, where the connection request message includes identification information of the target electronic device.

[0151] In some possible embodiments, the smart sofa constructs a connection request message, the connection request message includes identification information of the target electronic device, and the smart sofa sends the connection request message to the central control device.

[0152] S506: The central control device sends a connection information acquisition request to the target electronic device according to the connection request information.

[0153] In some possible embodiments, the central control device queries the identification information of the electronic device that has established a wireless connection with the central control device based on the identification information of the target electronic device, determines that the electronic device corresponding to the identification information that is the same as the identification information sent by the smart sofa is the target electronic device, and sends a connection information acquisition request to the target electronic device.

[0154] S507: The target electronic device receives the connection information acquisition request and sends the target connection information to the central control device.

[0155] S508, after receiving the target connection information, the central control device sends the target connection information to the smart sofa.

[0156] S509, after receiving the target connection information, the smart sofa establishes a communication connection with the target electronic device according to the target connection information.

[0157] S510, the smart sofa obtains display content of the target electronic device.

[0158] S511, the smart sofa projects the display content of the target electronic device through a projector.

[0159] Steps S507-S511 are similar to steps S307-S311 and will not be described again here.

[0160] For example, the pressure sensor located in the seat cushion detects a pressure value of 650N, and the pressure value pre-stored in the smart sofa memory is 600N. The smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value. At this time, the smart sofa determines that the user is using the smart sofa, and the smart sofa sends a broadcast message to the surrounding environment. After receiving the broadcast message, the smart phones and laptops in the surrounding environment return their own MAC address information, which is 00:1A:2B:3C:4D:5E and F0:9F:3C:8B:4A:6B respectively. The smart sofa queries the historical MAC address information pre-stored in the memory, which is 00:1A:2B:3C:4D:5E. The smart sofa determines that the smart sofa is in use. The mobile phone is the target electronic device, that is, the user located above the cushion is using the smart phone. The smart sofa sends a connection request message to the smart home central controller, and the connection request message includes the MAC address information of the smart phone 00:1A:2B:3C:4D:5E. After the smart home central controller receives the connection request message sent by the smart sofa, it checks whether the electronic devices that have established a wireless connection with the smart home central controller include the same MAC address information as the MAC address information sent by the smart sofa. If the smart phone and the smart home central controller have established a wireless connection in advance, the smart home central controller can determine that the smart phone is the target electronic device and send a connection information acquisition request to the smart phone. After receiving the connection information acquisition request sent by the central control device, the smart phone verifies the identity of the smart home central controller. After the identity verification is passed, the target connection information with the smart sofa is sent to the smart home central controller. After receiving the target connection information sent by the smart phone, the smart home central controller forwards the target connection information to the smart sofa. After receiving the target connection information from the smart phone, the smart sofa establishes a communication connection with the smart phone. The smart phone sends the image information, audio information, text information, etc. of the currently displayed page to the smart sofa by wireless transmission. The smart sofa then detects that the inclination angle of the backrest is 20° and the inclination angle of the footrest is 10°. The preset angle in the memory of the smart sofa is 30°. The smart sofa detects that the inclination angle of the backrest and the inclination angle of the footrest are both less than the preset angle. The smart sofa determines that the user who is using the smart sofa is in a lying position, then the smart sofa adjusts the lens of the projector to align with the second projection port on the hand placement surface on the upper surface of the armrest. The smart sofa projects the image information of the smart phone through the second projection port on the hand placement surface on the upper surface of the armrest through the projector to the wall or screen in front of the smart sofa. At the same time, a smart speaker is also provided on the smart sofa, which is used to synchronously play the audio information of the smart phone when the projector is projecting the image information and audio information on the smart phone.

[0161] The above embodiment demonstrates a method for identifying a target electronic device by comparing the identification information of the electronic device with the historical identification information, thereby optimizing the efficiency of the smart sofa in identifying the target electronic device.

[0162] Next, it is further introduced how to comprehensively utilize the positioning information and identification information of the electronic device to realize the identification of the target electronic device.

[0163] like Figure 6 As shown, it is a schematic flowchart 600 of another electronic device screen projection method provided in an embodiment of the present application, and the method includes:

[0164] S601, the smart sofa obtains the pressure value detected by the pressure sensor.

[0165] Step S601 is similar to step S301 and will not be described again here.

[0166] S602: When the pressure value is greater than a preset pressure value, the smart sofa sends a first detection signal to the surrounding environment.

[0167] Step S602 is similar to step S402 and will not be described again here.

[0168] S603, the smart sofa receives a feedback signal from the electronic device in response to the first detection signal, where the feedback signal includes positioning information and identification information of the electronic device.

[0169] In some possible embodiments, the smart sofa will continuously monitor the feedback signals returned by electronic devices in the surrounding environment in response to the broadcast signals. The feedback signals include positioning information of the electronic device, such as location coordinate information, which is used to indicate the position of the electronic device relative to the smart sofa, and device ID information, that is, the unique identification code of the electronic device, which is used to indicate the identity of the electronic device.

[0171] In some possible embodiments, the memory of the smart sofa stores historical identification information of electronic devices that are often in communication connection with the smart sofa. The smart sofa compares the identification information included in the feedback signal of the electronic devices in the surrounding environment for the first detection signal with the pre-stored historical identification information, and determines that the electronic devices in the surrounding environment corresponding to the identification information that is the same as the historical identification information are candidate electronic devices. The smart sofa calculates the distance between each electronic device and itself based on the positioning information such as coordinate information in the feedback signal of the electronic device and its own positioning information, and obtains the distance between each electronic device and the smart sofa.

[0172] S605: The smart sofa determines whether the electronic device corresponding to the minimum distance is a candidate electronic device.

[0173] In some possible embodiments, the smart sofa determines whether the target electronic device is a new connected device or an electronic device that has been connected to the smart sofa before by determining whether the electronic device corresponding to the minimum distance is one of the candidate electronic devices.

[0174] S606: The smart sofa determines that the electronic device corresponding to the shortest distance among the candidate electronic devices is the target electronic device.

[0175] In some possible embodiments, when the smart sofa determines that the identification information of the electronic device corresponding to the minimum distance belongs to historical identification information, the smart sofa determines that the target electronic device has established a connection with the smart sofa, and the smart sofa determines that the electronic device corresponding to the minimum distance among the candidate electronic devices is the target electronic device.

[0176] S607: The smart sofa determines that the electronic device corresponding to the minimum distance is the target electronic device, and adds the identification information of the target electronic device to the historical identification information.

[0177] In some possible embodiments, when the smart sofa determines that the identification information of the electronic device corresponding to the minimum distance does not belong to the historical identification information, the smart sofa determines that the target electronic device is a new electronic device, the smart sofa determines that the electronic device corresponding to the minimum distance is the target electronic device, and adds the identification information corresponding to the target electronic device to the historical identification information for quick identification of the electronic device next time.

[0178] S608, the smart sofa sends a connection request message to the central control device, where the connection request message includes the location information and identification information of the target electronic device.

[0179] In some possible embodiments, the smart sofa constructs a connection request message, the connection request message includes the location information and identification information of the target electronic device, and the smart sofa sends the connection request message to the central control device.

[0180] S609: The central control device sends a connection information acquisition request to the target electronic device according to the connection request information.

[0181] In some possible embodiments, the central control device queries the positioning information and identification information of the electronic device that has established a wireless connection with the central control device based on the positioning information and identification information of the target electronic device, determines that the electronic device with the same positioning information and identification information as those sent by the smart sofa is the target electronic device, and sends a connection information acquisition request to the target electronic device.

[0182] S610: The target electronic device receives a connection information acquisition request and sends target connection information to the central control device.

[0183] S611, after receiving the target connection information, the central control device sends the target connection information to the smart sofa.

[0184] S612, after receiving the target connection information, the smart sofa establishes a communication connection with the target electronic device according to the target connection information.

[0185] S613, the smart sofa obtains display content of the target electronic device.

[0186] S614, the smart sofa projects the display content of the target electronic device through a projector.

[0187] Steps S610-S614 are similar to steps S307-S311 and will not be described again here.

[0188] Exemplarily, the pressure sensor located in the seat cushion detects a pressure value of 720N, and the pressure value pre-stored in the smart sofa memory is 600N. The smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value. At this time, the smart sofa determines that the user is using the smart sofa, and the smart sofa sends broadcast information to the surrounding environment. There are three electronic devices in the surrounding environment, including a smart phone, a tablet computer and a laptop computer. After receiving the broadcast information, the smart phone returns its own MAC address information 00:1A:2B:3C:4D:5E and positioning information. After receiving the broadcast information, the tablet computer returns its own MAC address information F0:9F:3C:8B:4A:6B and positioning information. After receiving the broadcast information, the laptop computer returns its own MAC address information B2:5E:7D:8F:3C:1A and positioning information. The smart sofa queries the historical MAC address information pre-stored in the memory as 00:1A:2B:3C:4D:5E and F0:9F:3C:8B:4A:6B. The smart sofa compares the received MAC address information of the smart phone and the tablet computer, and determines that the smart phone and the tablet computer are candidate electronic devices. The smart sofa calculates the distance between each electronic device and itself according to the positioning information returned by the smart phone, tablet computer, and laptop computer and its own positioning information. The smart sofa determines that the laptop computer is the closest to itself, but the laptop computer is not a candidate electronic device, that is, the identification information of the laptop computer is not pre-stored in the memory. At this time, the smart sofa determines the laptop computer as the target electronic device, that is, the user located above the cushion is using the laptop computer, and stores the identification information of the laptop computer in the memory. The smart sofa sends a connection request message to the smart home central controller, and the connection request message includes the MAC address information B2:5E:7D:8F:3C:1A and positioning information of the laptop computer. After receiving the connection request message sent by the smart sofa, the smart home central controller checks whether the electronic devices that have established a wireless connection with the smart home central controller include electronic devices with the same MAC address information and the same identification information as those sent by the smart sofa. If the laptop computer has established a wireless connection or a priority connection with the smart home central controller in advance, the smart home central controller can determine that the laptop computer is the target electronic device and send a connection information acquisition request to the laptop computer. After receiving the connection information acquisition request sent by the central control device, the laptop computer verifies the identity of the smart home central controller. After the identity verification is passed, the target connection information with the smart sofa is sent to the smart home central controller. After receiving the target connection information sent by the laptop computer, the smart home central controller forwards the target connection information to the smart sofa. After receiving the target connection information from the laptop computer, the smart sofa establishes a communication connection with the laptop computer.The laptop computer sends the image information, audio information, text information, etc. of the currently displayed page to the smart sofa by wireless transmission. The smart sofa then detects that the inclination angle of the backrest is 20° and the inclination angle of the footrest is 10°. The preset angle in the memory of the smart sofa is 30°. The smart sofa detects that the inclination angle of the backrest and the inclination angle of the footrest are both less than the preset angle. The smart sofa determines that the user who is using the smart sofa is in a lying position, then the smart sofa adjusts the lens of the projector to align with the second projection port on the hand placement surface on the upper surface of the armrest. The smart sofa projects the image information of the laptop computer through the second projection port on the hand placement surface on the upper surface of the armrest through the projector to the wall or screen in front of the smart sofa. At the same time, a smart speaker is also provided on the smart sofa, which is used to synchronously play the audio information of the laptop computer when the projector is projecting the image information and text information on the laptop computer.

[0189] In the above embodiment, both the positioning information of the electronic device and the identification information of the electronic device are taken into consideration, further achieving a balance between the accuracy and speed of the smart sofa in identifying the target electronic device. Next, the physical connection between the smart sofa and the target electronic device is introduced.

[0190] like Figure 7 As shown, it is a schematic flowchart 700 of another electronic device screen projection method provided in an embodiment of the present application, and the method includes:

[0191] S701, the smart sofa obtains the pressure value detected by the pressure sensor.

[0192] Step S701 is similar to step S301 and will not be described again here.

[0193] S702, when the pressure value is greater than a preset pressure value, the accommodating cavity on the smart sofa control armrest opens and exposes the data transmission module.

[0194] In some possible embodiments, the memory of the smart sofa pre-stores pressure values ​​corresponding to the user's standard weight. When the control unit of the smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value, the smart sofa determines that the user is using the smart sofa, and the accommodating cavity on the smart sofa control armrest is in an open state. When the accommodating cavity is opened, the data transmission module contained in the accommodating cavity can be used to connect with the electronic device. The data transmission module may include but is not limited to a USB interface, a Type-C interface, an HDMI interface, an Ethernet interface, etc.

[0195] S703, the smart sofa controls the projector to project a preset prompt video.

[0196] In some possible embodiments, elderly users may not be very sensitive to the operation of electronic products. After the smart sofa controls the accommodating cavity to be in an open state and exposes the data transmission module, the smart sofa will detect the inclination angle of the backrest and the footrest, and judge the user's posture according to the inclination angle of the backrest and the footrest. When the smart sofa detects that the inclination angles of the backrest and the footrest are both less than the preset angle, the smart sofa determines that the user who is using the smart sofa is in a lying position, and the smart sofa controls and adjusts the lens angle of the projector to align it with the second projection port on the hand placement surface on the upper surface of the armrest. The smart sofa uses the projector to project the preset prompt video to the ceiling through the second projection port. When the smart sofa detects that the inclination angles of the backrest and the footrest are both greater than or equal to the preset angle, the smart sofa determines that the user who is using the smart sofa is in a sitting position, and the smart sofa uses the projector to project the preset prompt video to the ceiling through the first projection port. The preset prompt video is used to indicate the location of the data transmission module and demonstrate how to connect different types of electronic devices to the data transmission module, so as to guide the elderly user to complete the physical connection between the target electronic device and the data transmission module.

[0197] S704, the user physically connects the electronic device to the data transmission module according to the instructions in the prompt video, and the smart sofa determines that the electronic device physically connected to the data transmission module is the target electronic device.

[0198] In some possible embodiments, after the user physically connects the electronic device he is using with the data transmission module according to the preset prompt video, the smart sofa can identify the user's electronic device through the data transmission module, and the smart sofa determines that the electronic device physically connected to the data transmission module is the target electronic device.

[0199] S705, the smart sofa obtains display content of the target electronic device.

[0200] S706, the smart sofa projects the display content of the target electronic device through a projector.

[0201] Steps S705-S706 are similar to steps S310-S311 and will not be described in detail here.

[0202] Exemplarily, the pressure sensor located in the seat cushion detects a pressure value of 630N, and the pressure value pre-stored in the smart sofa memory is 600N. The smart sofa determines that the pressure value detected by the pressure sensor is greater than the preset pressure value. At this time, the smart sofa determines that the user is using the smart sofa, controls the accommodating cavity to be in an open state and exposes the Type-C data transmission interface. The smart sofa then detects that the inclination angle of the backrest is 60°, and the inclination angle of the footrest is 45°. The preset angle in the memory of the smart sofa is 30°. The smart sofa detects that the inclination angle of the backrest and the inclination angle of the footrest are both greater than the preset angle. The smart sofa determines that the user who is using the smart sofa is in a sitting position, and the smart sofa projects the preset prompt video through the first projection port on the front side of the armrest through the projector to the wall or screen in front of the smart sofa. According to the prompt video, the user physically connects the smartphone he is using to the Type-C data transmission interface. The smart sofa determines the smartphone as the target electronic device. The smartphone sends the image information, audio information, text information, etc. of the currently displayed page to the smart sofa by wireless transmission. The smart sofa then switches the projection content to the image information of the smartphone. At the same time, the smart sofa is also equipped with a smart speaker, which is used to synchronously play the audio information of the smartphone while the projector is projecting the image information and audio information on the smartphone.

[0203] The above embodiment shows that the smart sofa establishes a communication connection with the target electronic device through a physical connection.

[0206] In some possible embodiments, when the smart sofa detects that the inclination angles of the backrest 811 and the footrest 812 are both greater than or equal to the preset angle, the smart sofa determines that the user who is using the smart sofa is in a sitting position, and the smart sofa uses the projector 801 to project the display content of the target electronic device to the wall or curtain in front of the smart sofa through the first projection port 802. When the smart sofa detects that the inclination angles of the backrest 811 and the footrest 812 are both less than the preset angle, the smart sofa determines that the user who is using the smart sofa is in a lying position, and the smart sofa controls and adjusts the lens angle of the projector 801 to align it with the second projection port 803 of the hand placement surface 804 on the upper surface of the armrest, and the smart sofa uses the projector 801 to project the display content of the target electronic device to the ceiling through the second projection port 803.

[0207] In some possible embodiments, a accommodating cavity 808 is provided in the right armrest of the smart sofa. The accommodating cavity 808 is normally closed.
