[0002] As an upgraded product of traditional sofas, the functional sofa realizes the electric adjustment of various postures such as sitting posture and lying angle through the built-in linear drive system, aiming to improve the comfort and convenience of use. At present, the control core of the functional sofa on the market mainly depends on the physical hand controller. Although these hand controllers have different technical forms, for example, there are styles that need to directly press the button, or designs that use front and rear sliding covers for operation, but their essence all belong to the category that the user needs to contact and interact with specific physical controls. However, this interaction mode relying on physical hand controllers gradually shows its limitations. On the one hand, the operation mode is relatively single, and the user experience is poor; on the other hand, the specific form of physical keys or sliding structures has the risk of wear, looseness and failure after long-term use, affecting the durability of the product. For wireless hand controllers, although the wiring trouble is avoided, they usually use disposable batteries or rechargeable batteries for power supply, and there is a problem of needing to be replaced or charged regularly. If the power is exhausted or the user forgets the placement position of the hand controller, it will directly lead to the inability to use the function immediately. In addition, the connection line of some wired hand controllers is relatively long, and it is easy to be squeezed or entangled inside the sofa, which may cause line damage or contact failure.

[0017] This invention proposes a gesture control system, method, and a functional sofa for reclining sofas. It addresses the problems of limited operation methods and low reliability in existing reclining sofas. In this embodiment, a scanning and recognition module first scans the user's hand movements to obtain gesture pressure data. Then, a main control module and a data analysis module integrate and analyze the gesture pressure data to obtain gesture results. Finally, based on the gesture results, a drive module controls the reclining sofa. This system upgrades the reclining sofa's operation from a single interaction relying on physical buttons or sliding covers to intuitive gesture control. This not only enriches the reclining sofa's operation methods but also improves ease of use while reducing physical wear and tear and the risk of contact failures in buttons or sliding structures, thus enhancing the reclining sofa's reliability.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This invention provides a gesture control system, such as... Figure 1As shown, the gesture control system 20 includes a control terminal 21 and a functional sofa 22. The functional sofa 22 is communicatively connected to the control terminal 21. The control terminal 21 includes, but is not limited to, a hand controller, an APP, etc. The functional sofa 22 includes a controller 221, a motor 222, and a functional frame 223. The controller 221 controls the motor 222 to drive the functional frame 223 to move. The modules configured in the controller 221 and the specific functions implemented in the modules will be described in detail in the following embodiments. For the sake of simplicity, they will not be described in detail here.

[0020] Please see Figure 2 , Figure 2 A block diagram of the functional sofa gesture control system according to an embodiment of the present invention is shown, as follows: Figure 2 As shown, the functional sofa gesture control system 10 provided in this embodiment of the invention includes a scanning and recognition module 11, a main control module 12, a data analysis module 13, and a drive module 14. The scanning and recognition module 11 scans the user's hand movements to obtain gesture pressure data; the main control module 12 integrates the gesture pressure data sent by the scanning and recognition module 11 to obtain integrated gesture pressure data; the data analysis module 13 analyzes the integrated gesture pressure data sent by the main control module 12 to obtain gesture results and sends the gesture results to the main control module 12; the drive module 14 controls the functional sofa 22 according to the control commands sent by the main control module 12 corresponding to the gesture results. It should be noted that in this embodiment, as... Figure 2 As shown, the functional sofa gesture control system 10 also includes a manual intervention module 15, which is used to manually select whether to activate the gesture control function of the functional sofa 22. It should also be noted that in this embodiment, the manual intervention module 15, the scanning and recognition module 11, the data analysis module 13, and the drive module 14 are all connected to the main control module 12. Understandably, the controller 221 is configured with the manual intervention module 15, the scanning and recognition module 11, the data analysis module 13, the drive module 14, and the main control module 12, and all of these modules together constitute the functional sofa gesture control system 10. The functional sofa gesture control system 10 also includes a sofa body, which serves as the main carrier for all the above modules.

[0021] In some embodiments, such as this embodiment, as Figure 3As shown, the scanning and recognition module 11 includes an initialization submodule 111, a sampling submodule 112, and a data transmission submodule 113. The initialization submodule 111 is used to select the ADC (Analog-to-Digital Converter) channel and the sampling channel. The sampling submodule 112 is used to collect gesture pressure data of the user's hand operation based on the ADC channel and the sampling channel, and save the gesture pressure data to a global array. The data transmission submodule 113 is used to send the gesture pressure data in the global array to the main control module 12 via a serial port. Specifically, the sampling submodule 112 includes a sensing submodule, which is used to detect the user's hand gestures. More specifically, the sensing submodule includes a resistance sensing submodule and a capacitance sensing submodule. The resistance sensing submodule includes a resistance matrix sensor and is used to detect slapping gestures; the capacitance sensing submodule includes a capacitance matrix sensor and is used to detect swiping gestures. It should be noted that, in this embodiment, a slapping gesture includes, for example, slapping once, twice, three times, or four times on the armrest or backrest of the functional sofa 22; a sliding gesture includes, for example, sliding forward, backward, or diagonally on the upper, inner, or outer side of the armrest of the functional sofa 22. Understandably, in other embodiments, omnidirectional 360-degree slapping and sliding gestures may also be supported. It should also be noted that, in this embodiment, the ADC channel is the physical input pin of the analog-to-digital converter, responsible for receiving the gesture-based analog pressure signals from the resistor matrix sensor and the capacitor matrix sensor; the sampling channel is a logical path configured at the software or register level, which determines which ADC channel's signal is selected and enters the subsequent sample-and-hold circuit for conversion. Understandably, the ADC channel is a "hardware port," and the sampling channel is a "software path," and the two work together to ensure the correct acquisition of gesture pressure data. It should also be noted that in this embodiment, the resistor matrix sensor is a 1-row, 12-column resistor matrix, and the capacitor matrix sensor is a 1-row, 8-column capacitor matrix. Understandably, in other embodiments, the number of rows and columns of the resistor matrix and capacitor matrix can be determined according to the actual situation, and no specific limitation is made here.

[0022] In some embodiments, such as this embodiment, as Figure 4As shown, the main control module 12 includes a definition submodule 121, a detection submodule 122, a verification submodule 123, and a mapping submodule 124. The definition submodule 121 defines a global structure; the detection submodule 122 detects whether the length of the gesture pressure data is a preset length; the verification submodule 123 performs a CRC (Cyclical Redundancy Check) check on the gesture pressure data when the length is the preset length, and copies the gesture pressure data into the global structure to obtain the integrated gesture pressure data when the check result is successful; the mapping submodule 124 maps the gesture result to the control command. It should be noted that in this embodiment, length checking and CRC verification ensure data integrity, and copying the gesture pressure data that has passed length checking and CRC verification into the global structure to obtain the integrated gesture pressure data provides a standardized format for subsequent analysis. It should also be noted that, in this embodiment, the mapping submodule 124 accurately converts the identified abstract gesture results (such as "tap twice" or "swipe right") into specific control commands that the driving module 14 can understand and execute, according to the preset gesture command mapping table.

[0023] In some embodiments, such as this embodiment, as Figure 5As shown, the data analysis module 13 includes a basic action discrimination submodule 131, a gesture recognition submodule 132, and a gesture sending submodule 133. The gesture recognition submodule 132 is used to identify complex gestures by analyzing the combination of the basic actions to obtain the gesture result. Continuous pressing and lifting at the same focus coordinate is identified as a slapping action, and continuous movement of the focus on the coordinate is identified as a sliding action. The gesture sending submodule 133 is used to send the gesture result to the main control module 12. It should be noted that in this embodiment, continuous pressing and lifting at the same focus coordinate is recognized as a tapping action, and continuous movement of the focus on the coordinate is recognized as a sliding action. For example, if a finger quickly completes two actions, "pressing" and "lifting," at the same position (e.g., coordinates (100, 200), it is recognized as a single click; if two such operations are performed consecutively within a short period of time, it is recognized as a double click; for example, if a finger starts touching the screen at coordinates (100, 200), then moves to coordinates (300, 200) and lifts, it is recognized as a horizontal rightward sliding action by tracking the continuous change trajectory of the focus coordinate. It should also be noted that in this embodiment, after the data analysis module 13 sends the gesture result to the active module, the main control module 12 maps the gesture result into control commands and sends the control commands to the drive module 14. The drive module 14 controls the functional sofa 22 according to the control commands, and the control specifically includes heating, massage, light on / off, opening, retracting, and stopping the functional shelf 223. For ease of understanding, the following examples illustrate the process: A single tap stops the function shelf 223; two taps open the function shelf 223; three taps retract the function shelf 223; sliding forward opens the function shelf 223; sliding backward stops the function shelf 223; sliding upward turns on heating, and sliding downward turns off heating; circling clockwise on a specific area of ​​the armrest activates the massage, while circling counterclockwise switches the massage mode or turns it off; two quick taps on the top area of ​​the functional sofa 22 turn on the ambient lighting; a long press turns off all lights.

[0024] Please refer to Figure 6 , Figure 6 A flowchart illustrating the gesture control method for a functional sofa according to an embodiment of the present invention is shown, as follows: Figure 6 As shown, the gesture control method for the functional sofa includes steps S110-S120.

[0025] S110. If a preset switch command is received, the gesture pressure data is acquired and the gesture pressure data is integrated to obtain gesture integrated pressure data.

[0026] In this embodiment, the step of acquiring gesture pressure data includes: selecting and enabling the corresponding ADC channel and sampling channel; and converting the detected simulated pressure signal of the user's hand operation into the gesture pressure data through the ADC channel. It should be noted that in this embodiment, the functional sofa gesture control method is applied to the aforementioned functional sofa gesture control system; the functional sofa is powered on and initialized by the user turning on the physical switch on the hand controller, entering a standby or operable state. Subsequently, if the user performs a gesture operation, the gesture pressure data can be acquired through the scanning and recognition module, and the gesture pressure data is integrated by the main control module to obtain integrated gesture pressure data.

[0027] Furthermore, the step of integrating the gesture pressure data to obtain integrated gesture pressure data includes: detecting whether the length of the gesture pressure data is a preset length; If the length of the gesture pressure data is the preset length, a CRC check is performed on the gesture pressure data to obtain a check result; the integrated gesture pressure data is obtained based on the check result and the gesture pressure data. Specifically, the step of analyzing the integrated gesture pressure data to obtain the gesture result includes: if the check result is a check failure, the gesture pressure data is discarded or an error code is returned; if the check result is a check success, the gesture pressure data is copied to a predefined global structure to obtain the integrated gesture pressure data. It should be noted that in this embodiment, the dual checks of length and CRC can effectively filter out erroneous or incomplete data caused by transmission interference, ensuring the input quality for subsequent analysis. After successful check, the gesture pressure data is copied to a predefined global structure, providing the algorithm analysis module with uniformly formatted and memory-organized data input, thereby improving stability and recognition accuracy.

[0028] S120. Analyze the integrated pressure data of the gesture to obtain the gesture result, and control the functional sofa according to the gesture result.

[0029] In this embodiment, an algorithm analysis module identifies three basic actions—pressing, lifting, and focus coordinates—from the integrated pressure data of the gestures. Combinations of these basic actions are analyzed to identify complex gestures, resulting in the gesture outcome. The functional sofa is then controlled via a drive module and a main control module based on the gesture outcome. Specifically, the step of analyzing combinations of basic actions to identify complex gestures includes: combining the identified basic actions into a sequence of actions in chronological order; and matching the sequence of actions with a predefined complex gesture pattern to obtain the gesture outcome. More specifically, the step of controlling the functional sofa based on the gesture outcome includes: mapping the gesture outcome to a control command using a preset gesture command mapping table; and controlling the functional sofa according to the control command. It should be noted that in this embodiment, different gestures correspond to different control functions. For example, tapping twice on the left armrest corresponds to starting / stopping the massage function; sliding forward on the armrest surface corresponds to opening the massage rack; custom gestures are supported, for example, tapping three times on the right armrest switches the massage mode.

[0030] To facilitate understanding, the following example illustrates the gesture control system and methods for reclining sofas, using the example of a user wanting to straighten the backrest of a reclining sofa to make it easier to get up: When a user places their hand on the armrest of the recliner and makes a quick backward sliding gesture, a built-in capacitive matrix sensor under the armrest detects the capacitance changes caused by the hand's proximity and movement in real time, while a resistive matrix sensor simultaneously monitors for slight pressure. The ADC channel inside the scanning and recognition module samples these continuous gesture-based pressure signals and converts them into gesture pressure data, which is then saved to a global array. The main control module checks the received gesture pressure data for length and CRC verification to ensure that no errors or loss occurred during transmission. If the verification fails, the gesture pressure data is discarded and prepared for the next data acquisition. If the verification passes, the gesture pressure data is integrated and copied into a predefined global structure to form standardized "integrated gesture pressure data." The data analysis module then identifies the integrated gesture pressure data. The system first identifies the pressing, lifting, and focus coordinates. Then, it analyzes the combination and timing of these basic actions. For example, in this embodiment, it identifies a continuous backward displacement of the focus coordinates within a short period of time, without any strong pressing signal. This highly matches the preset "slide backward" gesture pattern in the library. Based on this, the gesture result is determined to be "slide backward." After receiving the information that "the gesture result is slide backward," the main control module immediately queries its internal gesture command mapping table. The gesture command mapping table clearly indicates that "slide backward" corresponds to the control command of "retract the functional frame" or "adjust the backrest." Therefore, the main control module sends the corresponding instruction to the drive module. The drive module (such as a motor driver) then acts to generate a precise control signal (such as a specific voltage) to drive the motor in the backrest of the functional sofa to operate, smoothly adjusting the backrest to an upright posture and assisting the user to get up easily.

[0031] In summary, the functional sofa gesture control method in this embodiment of the invention directly converts user gestures such as patting and sliding into control commands for the sofa, greatly improving the convenience of operation and user experience. Users can adjust the posture or function of the functional sofa without searching for or touching the hand controller. In terms of technical implementation, a series of operations, such as ADC channel selection, data length checking, CRC verification, and copying valid data to the global structure, ensure the high reliability and integrity of the data processing stage from the acquisition of gesture simulation pressure signals, laying a solid foundation for subsequent accurate recognition. At the recognition level, by analyzing basic actions such as pressing, lifting, and focus coordinates and combining them into sequences and matching them with predefined complex gesture patterns, complex gesture intentions can be accurately distinguished, effectively reducing the false recognition rate. In addition, the preset gesture command mapping table makes the correspondence between gestures and sofa functions (such as backrest adjustment, heating, massage, etc.) highly customizable, meeting the personalized needs of different users and enhancing flexibility and practicality.
