Description

Technical Field

[0001] This invention relates to the field of human-computer interaction technology, specifically to a dual-wearable, multi-functional television remote control interaction method, device, and storage medium. Background Technology

[0002] With the improvement of the processing power of smart terminals, human-computer interaction technology has evolved from traditional physical button arrays to natural user interfaces. In the control scenarios of smart TVs and large-screen display devices, in addition to traditional infrared / Bluetooth remote controls and voice commands, wearable gesture input devices based on microelectromechanical systems (MEMS) sensors have attracted much attention due to their non-contact and high degree of spatial freedom. These devices typically collect user motion data through built-in inertial measurement units or capacitive touch units, which are then mapped into control commands after being processed by algorithms. Among them, wearable remote control rings recognize user gestures through built-in gyroscopes, accelerometers, or touch sliding areas, and then send commands to the TV or base station to control the TV. These products aim to provide an intuitive, compact, and immersive viewing experience that is easy to use in a sofa setting.

[0003] However, existing wearable input solutions mostly use single devices (such as a single smart ring) as signal acquisition sources, which presents the following technical bottlenecks in the actual input interface processing and command mapping process: Due to limitations in size and touch area, single-ring devices cannot provide enough input channels to map all the full functions of a TV remote control. Therefore, users cannot achieve complete control of the TV using only the ring. To compensate for this limitation, existing single-ring solutions typically employ a mode-switching design. For example, users switch the recognition mode of the current touch area via specific gestures or buttons, toggling between "up / down mode" and "left / right mode." This manual switching process is unintuitive, increasing the user's mental burden and operational flow, severely impacting the smoothness and immersion of remote control interaction. Single-ring devices also need to utilize limited touch or sensor data to distinguish between various complex gestures (such as differentiating between single-finger swipes and fingertip taps), resulting in low gesture recognition accuracy and unstable interaction response, and a high risk of accidental touches.

[0004] To address this, a dual-wearable, split-function television remote control interaction method, device, and storage medium are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-wearable, collaborative television remote control interaction method, device, and storage medium, which achieves efficient and comfortable blind operation interaction of the television through the division of labor and coordination of micro-movements of the left and right hands.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A dual-wearable, distributed-function television remote control interaction method, which controls a television terminal connected to a smart base station via a smart base station, includes: Receive a first operation signal from the left smart ring worn on the user's left hand. The first operation signal corresponds to the up and down navigation keys and the confirmation key operation command in human-computer interaction. Receive a second operation signal from the right smart ring worn on the user's right hand, the second operation signal corresponding to the left and right navigation keys and the exit operation command in human-computer interaction; Receive a third operation signal from the left smart ring and the right smart ring, the third operation signal being triggered by the left smart ring and the right smart ring simultaneously performing a predetermined action; The predetermined actions include: the left smart ring and the right smart ring sliding in the same direction simultaneously, sliding in opposite directions simultaneously, and / or performing coordinated sliding in any combination of directions; The third operation signal corresponds to the remote control's volume adjustment, channel switching, system menu and / or other advanced collaborative function commands; The first operation signal, the second operation signal, and the third operation signal are triggered by the user performing natural micro-gestures, which include fingertip twitching, light touching, and / or short swipes.

[0007] Preferably, the smart base station parses the first operation signal, the second operation signal, and the third operation signal to obtain a parsing instruction; The smart base station converts the parsed instructions into standard USB keyboard event key values; The smart base station simulates a USB keyboard HID device through a USB interface, reporting the standard USB keyboard event key values ​​to the TV terminal, thereby controlling the TV user interface without modifying the TV terminal.

[0008] Preferably, the smart base station receives the first operation signal, the second operation signal, and the third operation signal via Bluetooth protocol.

[0009] Preferably, the left smart ring and / or the right smart ring automatically enter a sleep state after remaining stationary for a set period of time; After the smart base station detects the movement event of the left smart ring and / or the right smart ring, it automatically wakes up the communication channel. The smart base station maintains a long-term BLE connection with the left and right smart rings and supports dynamic modeling and left / right ring identity memory mechanism, automatically identifying and confirming the wearing identity of the left and / or right hand during multiple wears.

[0010] Preferably, the step of the smart base station automatically confirming the left and right hand wearing the rings through the left and right ring identity memory mechanism includes: Obtain rotational bias score, position score, and historical consistency score. The calculation steps for the rotational bias score are as follows: within a preset sliding window, count the number of clockwise events and the number of counterclockwise events of the ring gyroscope angular velocity in the horizontal axis direction. Calculate the score using the ratio of the number of clockwise and counterclockwise events. If the score is greater than zero, it is determined that the ring is biased towards the right hand; if the score is less than zero, it is determined that the ring is biased towards the left hand. The steps for calculating the position score are as follows: establish a spatial coordinate system based on the base station reference axis, analyze the relative coordinates of the two rings projected onto the horizontal plane, and determine the orientation of the coordinates in combination with the human body midline, and determine the ring located on the right side of the human body midline as having right-hand characteristics. The steps for calculating the historical consistency score are as follows: a sliding voting algorithm is used to suppress accidental reversals and jumps within a preset time. The right-hand probability score is calculated by weighting and summing the rotational skewness score, the positional score, and the historical consistency score. When the probability score for the right hand is greater than the preset high threshold, the ring is determined to be worn on the right hand; when the score is between the preset low threshold and the high threshold, it is recorded as an uncertain state and the data is continuously observed until the data converges and the identity is automatically confirmed.

[0011] Preferably, the smart base station monitors the trigger timestamps of the first operation signal from the left smart ring and the second operation signal from the right smart ring in real time; If the triggering time interval between the first operation signal and the second operation signal is greater than a preset time threshold, the smart base station will parse and report the corresponding TV remote control commands in the order of reception. If the triggering time interval between the first operation signal and the second operation signal is less than and / or equal to the preset time threshold, the smart base station determines that the current operation is a potential collaborative action and enters the collaborative instruction verification state. In the collaborative instruction verification state, if the reported signals of the two rings do not conform to the preset third operation signal gesture characteristics, the smart base station executes a unilateral instruction according to the preset priority weight.

[0012] A dual-wearable, multi-functional TV remote control interactive device for controlling a TV terminal includes a left smart ring, a right smart ring, and a smart base station. The left smart ring has a built-in Bluetooth module, a button touch unit, and a low-power sensor, which are used to generate and send a first operation signal. The first operation signal corresponds to the up and down navigation keys and the confirmation key operation command of the remote control. The right smart ring has a built-in Bluetooth module, a button touch unit, and a low-power sensor, which are used to generate and send a second operation signal. The second operation signal corresponds to the operation commands of the left and right navigation keys and the exit key of the remote control. The smart base station is equipped with a Bluetooth receiver module and a USB interface; The Bluetooth receiving module receives the first operation signal from the left smart ring and the second operation signal from the right smart ring. Used to receive a third operation signal from the left smart ring and the right smart ring, the third operation signal being triggered by the left smart ring and the right smart ring simultaneously performing a predetermined action; Used to parse the received signal and convert it into standard USB keyboard event key values; The device connects to the television via the USB interface and simulates a USB keyboard HID device, reporting the key values ​​to the television to control the television user interface.

[0013] A dual-wearable, multi-functional television remote control interactive storage medium includes: the medium storing computer program instructions, which, when executed by the smart base station, enable the smart base station to implement the dual-wearable, multi-functional television remote control interactive method.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention innovatively adopts a dual-wear design with separate functions for left and right rings, naturally distributing the complete remote control functions (up, down, left, right, confirm, return) to the left and right rings, and supporting complex coordinated actions. This eliminates the cumbersome mode switching required in existing single-ring solutions, achieving full-function remote control without increasing the user's cognitive burden. Simultaneously, the expansion of the left and right input channels significantly improves the efficiency of command recognition and the smoothness of interaction.

[0015] 2. The dual-ring signals are converted into standard USB keyboard events via a smart base station and reported to the TV in the form of a simulated USB HID device. This core technical solution achieves protocol bridging between "wearable devices and traditional TV input interfaces." Therefore, this invention does not require the installation of any drivers or dedicated apps on the TV, making it compatible with mainstream smart TV systems on the market, achieving plug-and-play functionality, and greatly enhancing the product's universality and ease of use.

[0016] 3. This invention introduces a dynamic modeling and left / right ring identification memory mechanism, combined with a probabilistic recognition algorithm, to automatically confirm the left / right hand identity during multiple wears, eliminating the need for manual configuration by the user. Simultaneously, the system supports low-power sleep mode and automatic wake-up during motion events, ensuring ultra-long battery life. These system-level optimizations effectively reduce the user's operational threshold and maintenance costs, guaranteeing stability and reliability during wear and use. Attached Figure Description

Figure 2 This is a flowchart of a dual-wearable, division-of-labor television remote control interaction method proposed in this invention. Figure 3 This is a flowchart of the method for the left and right ring identity memory mechanism proposed in this invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figures 1 to 3 This invention provides a dual-wearable, collaborative television remote control interaction method, the technical solution of which is as follows: A dual-wearable, collaborative television remote control interaction method, such as... Figures 1-2 As shown, it includes: A dual-wearable, distributed-function television remote control interaction method, which controls a television terminal connected to a smart base station via a smart base station, includes: Receive a first operation signal from the left smart ring worn on the user's left hand. The first operation signal corresponds to the up and down navigation keys and the confirmation key operation command in human-computer interaction. Receive a second operation signal from the right smart ring worn on the user's right hand, the second operation signal corresponding to the left and right navigation keys and the exit operation command in human-computer interaction; Receive a third operation signal from the left smart ring and the right smart ring, the third operation signal being triggered by the left smart ring and the right smart ring simultaneously performing a predetermined action; The predetermined actions include: the left smart ring and the right smart ring sliding in the same direction simultaneously, sliding in opposite directions simultaneously, and / or performing coordinated sliding in any combination of directions; The third operation signal corresponds to the remote control's volume adjustment, channel switching, system menu and / or other advanced collaborative function commands; The first operation signal, the second operation signal, and the third operation signal are triggered by the user performing natural micro-gestures, which include fingertip twitching, light touching, and / or short swipes.

[0020] The third operation signal also includes a virtual knob continuous adjustment command: when the left smart ring and the right smart ring simultaneously maintain a predetermined trigger posture, the smart base station monitors the roll angle change of either ring around its longitudinal axis, maps the roll angle change into a continuous pulse signal for volume increase or decrease or video progress bar adjustment, and reports it to the TV.

[0021] The predetermined trigger posture of the virtual knob refers to the accelerometer readings of the two rings being consistent along the vertical axis, and the cross-correlation coefficient being greater than 0.85 within a 100ms window, representing a synchronized, static state with both hands placed parallel to each other. In this state, the system activates the roll angle monitoring engine, ignoring minute jitters with a modulus less than 5° / s, and only accumulating and converting continuous roll changes exceeding the preset dead zone into adjustment pulses to ensure smooth control.

[0022] This invention effectively solves the inefficiency problem of traditional discrete buttons requiring frequent clicks or long presses when adjusting volume or video progress by simulating the interaction logic of a physical knob. Utilizing the natural rotation of the wrist, it achieves precise and continuous control of analog quantities, balancing the agility of large-scale adjustments with the accuracy of fine-tuning. This greatly reduces finger fatigue from repetitive operations and significantly improves the intuitiveness and smoothness of blind operation.

[0023] Furthermore, the smart base station analyzes the first operation signal, the second operation signal, and the third operation signal to obtain an analysis instruction; The smart base station converts the parsed instructions into standard USB keyboard event key values; The smart base station simulates a USB keyboard HID device through a USB interface, reporting the standard USB keyboard event key values ​​to the TV terminal, thereby controlling the TV user interface without modifying the TV terminal.

[0024] Specifically, the smart base station internally stores a preset instruction mapping table to convert non-standard Bluetooth gesture signals into Usage IDs conforming to the standard USB HID protocol. For example, a "finger twitch" triggered by the left smart ring is mapped to the "Enter key (Usage ID: 0x28)"; a "short swipe" triggered by the right smart ring is mapped to the "Exit key (ESC, Usage ID: 0x29)". For volume adjustment in the third operation signal, the base station converts it into volume up / down key values ​​under the consumer control device category. This mapping mechanism allows the TV to recognize the smart base station as a standard input device, thereby directly calling the underlying navigation logic without installing additional drivers or modifying the system layer.

[0025] By pre-setting a command mapping table in the smart base station, non-standard ring gesture signals are accurately converted into Usage IDs of the standard USBHID protocol. This mechanism successfully achieves protocol bridging between wearable devices and traditional TV input interfaces, enabling the TV to recognize it as a standard keyboard. Its core advantage lies in enhancing the product's versatility; it allows for plug-and-play full-function control without requiring driver installation or system modifications on the TV, improving the smoothness and compatibility of the interaction.

[0026] Furthermore, the smart base station receives the first operation signal, the second operation signal, and the third operation signal via Bluetooth protocol. Bluetooth protocol offers lower transmission latency and a more stable connection.

[0027] After the smart base station confirms that the received operation signal has been successfully parsed and reported to the TV, it sends a tactile feedback command to the left and right smart rings via the Bluetooth communication channel. The tactile actuators built into the left and right smart rings perform vibrations at a preset frequency according to the tactile feedback command. The vibrations include a single short vibration for the confirmation button operation command and a bilateral synchronous long vibration for the collaborative function command.

[0028] This invention introduces a two-way haptic interaction mechanism, effectively solving the problem of lack of feedback in blind operation scenarios. Through differentiated vibration modes, users can intuitively perceive whether commands have been successfully parsed and reported without looking at the screen. This closed-loop feedback design completely eliminates the uncertainty of operation, significantly enhancing users' confidence and experience in immersive movie viewing.

[0029] Furthermore, the left smart ring and / or the right smart ring automatically enter a sleep state after remaining stationary for a set period of time; After the smart base station detects the movement event of the left smart ring and / or the right smart ring, it automatically wakes up the communication channel. The smart base station maintains a long-term BLE connection with the left and right smart rings and supports dynamic modeling and left / right ring identity memory mechanism, automatically identifying and confirming the wearing identity of the left and / or right hand during multiple wears.

[0030] The identity memory mechanism establishes a correlation matrix between the device's unique identifier (MAC address) and the worn tag in the non-volatile storage module of the smart base station. When the system is used for the first time or when the wearer is changed, the base station enters an active learning mode, continuously collecting more than 10 sets of sliding trajectory features to calculate the aforementioned score. The right-hand probability score corresponding to a certain MAC address is then calculated. When the convergence value is above 0.7 three times consecutively, the system completes calibration and locks the identity. In subsequent wear, the base station only needs to perform a brief hand-holding self-test to complete the identity backtracking within 1 second, realizing a rapid cold start of the interaction mode.

[0031] This embodiment, through BLE long connection and automatic sleep / wake mechanism, greatly extends the battery life of wearable devices while ensuring millisecond-level response. It not only solves the complexity of pairing multiple devices but also completes rapid cold start with just one second of hand-held self-test, completely eliminating the tedious manual configuration for users and significantly improving the intelligence and convenience of interaction in multiple users and scenarios.

[0032] Furthermore, such as Figure 3 As shown, the steps by which the smart base station automatically confirms the left and right hand wearing the rings through the left and right ring identity memory mechanism include: Obtain rotational bias score, position score, and historical consistency score. The calculation steps for the rotational bias score are as follows: within a preset sliding window, count the number of clockwise events and the number of counterclockwise events of the ring gyroscope angular velocity in the horizontal axis direction. Calculate the score using the ratio of the number of clockwise and counterclockwise events. If the score is greater than zero, it is determined that the ring is biased towards the right hand; if the score is less than zero, it is determined that the ring is biased towards the left hand. The steps for calculating the position score are as follows: establish a spatial coordinate system based on the base station reference axis, analyze the relative coordinates of the two rings projected onto the horizontal plane, and determine the orientation of the coordinates in combination with the human body midline, and determine the ring located on the right side of the human body midline as having right-hand characteristics. The steps for calculating the historical consistency score are as follows: a sliding voting algorithm is used to suppress accidental reversals and jumps within a preset time. The right-hand probability score is calculated by weighting and summing the rotational skewness score, the positional score, and the historical consistency score. When the probability score for the right hand is greater than the preset high threshold, the ring is determined to be worn on the right hand; when the score is between the preset low threshold and the high threshold, it is recorded as an uncertain state and the data is continuously observed until the data converges and the identity is automatically confirmed.

[0033] Specifically, in calculating the rotational skewness score The system predefines typical viewing postures (such as palms down or palms facing each other) as calibration benchmarks. The angular velocity of the ring gyroscope along the horizontal axis (i.e., the axis perpendicular to the gravity vector and parallel to the ground) is discretized, and a signal with an angular velocity magnitude greater than 30° / s and a duration exceeding 40 ms is defined as a valid rotation event. The number of clockwise events within the sliding window is counted. Number of counter-clockwise events According to the formula ; Calculate the score, where It is a very small constant to prevent the denominator from being zero.

[0034] Location score The analysis is based on the channel detection function in the Bluetooth protocol. The smart base station uses a multi-antenna array to obtain the absolute distance and angle of arrival information of the left and right smart rings relative to the base station through phase measurement or round-trip time measurement. Scores are obtained by projecting the spatial coordinates of the two rings onto a horizontal plane and comparing their azimuth deviations on either side of the body's midline. If ring A is located in the right-handed habitual operating area (to the right of the midline), then its It tends towards 1, and conversely, it tends towards 0.

[0035] The system uses a multi-factor weighted fusion model to calculate the final right-hand probability score. The specific formula is described as follows: the right-hand probability score is equal to the sum of 0.5 times the rotation skewness score, 0.35 times the position score, and 0.15 times the historical consistency score. Wherein, the historical consistency score... The decision results within the preceding 1 to 2 seconds are smoothed using a first-order IIR filter to suppress occasional motion reversal noise.

[0036] During the judgment stage, when When the score exceeds a preset high threshold of 0.7, the smart base station immediately determines that the ring is worn on the right hand and logically binds its Bluetooth MAC address to the right-hand command set (left, right navigation, and exit). When the score is between 0.4 and 0.7, the system marks it as "uncertain" and continues to accumulate sampled data. Once the identity is confirmed, the smart base station dynamically adjusts the HID key-value mapping logic reported by the two rings to the TV by updating the internal mapping table, ensuring that the user can achieve full-function interaction without manually switching modes.

[0037] This embodiment achieves extremely high accuracy and robustness in wearable device identification through a three-dimensional deep fusion algorithm that considers rotational bias, spatial position, and historical consistency. It automatically identifies the left or right hand using Bluetooth channel detection technology and physical motion characteristics, eliminating the cumbersome initial setup process of traditional devices.

[0038] Furthermore, when determining the cooperative sliding, the smart base station extracts the projections of the angular velocity vectors collected by the gyroscopes built into the two rings onto the horizontal plane, and calculates the angle between the two sets of vectors. .like If the deviation in sliding speed on both sides is less than 20%, it is determined to be "simultaneous sliding in the same direction"; if If so, it is determined as "sliding in opposite directions at the same time".

[0039] Furthermore, the smart base station is equipped with a time synchronization window. Its value ranges from 50ms to 150ms. When the base station receives signal A from the left smart ring, it starts the timer; if... If signal B from the right smart ring is received within a certain time, the feature vectors of A and B are extracted and matched collaboratively. If both A and B are "short swipes in the same direction," it is interpreted as a continuous volume adjustment command; if the signal interval exceeds [a certain value], it is interpreted as a continuous volume adjustment command. If the system determines that the signal is a single-sided first operation signal and a second operation signal, it will avoid false triggering due to wireless communication delay.

[0040] Furthermore, the smart base station monitors in real time the trigger timestamps of the first operation signal from the left smart ring and the second operation signal from the right smart ring; If the triggering time interval between the first operation signal and the second operation signal is greater than a preset time threshold, the smart base station will parse and report the corresponding TV remote control commands in the order of reception. If the triggering time interval between the first operation signal and the second operation signal is less than or equal to the preset time threshold, the smart base station determines that the current operation is a potential collaborative action and enters the collaborative instruction verification state. In the collaborative instruction verification state, if the reported signals of the two rings do not conform to the preset third operation signal gesture characteristics, the smart base station executes a unilateral instruction according to the preset priority weight.

[0041] The preset priority weights are divided into three levels based on the interaction security level: the highest priority is system-level instructions (such as the exit button and power button), the second highest priority is confirmation instructions, and the normal priority is navigation and adjustment instructions. System-level instructions are set to 100, confirmation instructions to 80, and navigation and adjustment instructions to 50. When two rings report conflict signals within a very short time (e.g., the left hand clicks confirmation while the right hand performs swipe navigation) and the coordination conditions are not met, the base station will search the priority table, prioritize forwarding the higher-priority confirmation instruction to the TV, and discard the lower-priority navigation instruction. If the priorities are the same, the first valid signal arriving at the base station will be executed according to the time order.

[0042] This embodiment effectively resolves command conflicts and accidental touches in dual-device interaction through timestamp monitoring and a multi-level priority arbitration mechanism. It accurately identifies independent actions on one side and collaborative actions on both sides, ensuring the precise execution of complex interaction logic. By introducing a tiered priority system, system-level and confirmation-level core commands are prioritized in conflict scenarios, improving the stability and security of operation.

[0043] The sensors inside the left and right smart rings collect the gravitational acceleration components in real time. When the angle between the calculated gravitational acceleration vector and a specific axis of the ring coordinate system is within a preset downward range, the system determines that it is currently in a natural relaxed state and automatically blocks the first or second operation signal generated by the ring.

[0044] This invention is based on gravity vector attitude calculation to accurately identify the user's relaxed arm state from a physical perspective. When the system detects a naturally drooping hand, it automatically blocks the signal input, eliminating accidental touch interference caused by unconscious finger movements or clothing friction.

[0045] This embodiment utilizes a dual-wear design with separate functions for the left and right hands, naturally distributing the complete remote control functionality to both ends and completely eliminating the cumbersome operation of frequent mode switching inherent in single-ring solutions. The system supports natural micro-motion triggering; through the efficient coordination and division of labor between the left and right hands, it not only expands the command channels for human-computer interaction but also significantly improves the accuracy and response speed of gesture recognition. This design reduces the user's mental burden, achieving a more intuitive and fluid TV blind operation experience, greatly enhancing the immersion during viewing.

[0046] Example 2 This embodiment provides a dual-wearable, multi-tasking television remote control interactive device, the technical solution of which is as follows: A dual-wearable, multi-functional TV remote control interactive device for controlling a TV terminal includes a left smart ring, a right smart ring, and a smart base station. The left smart ring has a built-in Bluetooth module, a button touch unit, and a low-power sensor, which are used to generate and send a first operation signal. The first operation signal corresponds to the up and down navigation keys and the confirmation key operation command of the remote control. The right smart ring has a built-in Bluetooth module, a button touch unit, and a low-power sensor, which are used to generate and send a second operation signal. The second operation signal corresponds to the operation commands of the left and right navigation keys and the exit key of the remote control. The smart base station is equipped with a Bluetooth receiver module and a USB interface; The Bluetooth receiving module receives the first operation signal from the left smart ring and the second operation signal from the right smart ring. Used to receive a third operation signal from the left smart ring and the right smart ring, the third operation signal being triggered by the left smart ring and the right smart ring simultaneously performing a predetermined action; Used to parse the received signal and convert it into standard USB keyboard event key values; The device connects to the television via the USB interface and simulates a USB keyboard HID device, reporting the key values ​​to the television to control the television user interface.

[0047] During the specific command conversion process, the smart base station stores a preset command mapping table to convert non-standard Bluetooth gesture signals into Usage IDs that conform to the standard USB HID protocol. For example, a "finger twitch" triggered by the left smart ring is mapped to the "Enter key (Usage ID: 0x28)," and a "short swipe" triggered by the right smart ring is mapped to the "Exit key (ESC, Usage ID: 0x29)." For volume adjustment in the third operation signal, the base station converts it into volume up / down key values ​​under the consumer control device category. This mapping mechanism allows the TV to recognize the smart base station as a standard input device, thereby directly calling the underlying navigation logic.

[0048] The smart base station automatically identifies the wearer's hand by using a left / right ring identification memory mechanism. The system obtains rotational skewness scores, position scores, and historical consistency scores, and then calculates a weighted sum to arrive at a right-hand probability score. The position score is analyzed based on the channel sounding function in the Bluetooth protocol. The base station uses a multi-antenna array to obtain the absolute distance and angle of arrival information of the ring relative to the base station through phase measurement or round-trip time measurement. When the score exceeds a high threshold of 0.7, the base station determines that the ring is worn on the right hand and logically binds its Bluetooth MAC address to the right-hand command set, dynamically adjusting the HID key-value mapping logic reported to the television.

[0049] The smart base station monitors the trigger timestamps of signals from the left and right smart rings in real time. If the trigger interval is less than or equal to a preset time threshold (e.g., 50ms to 150ms), the base station determines it as a potential coordinated action. If it does not meet the coordinated characteristics, the base station executes a unilateral command according to a preset priority weight, with system-level commands (e.g., exit button, power button) having the highest priority, followed by confirmation commands, and navigation and adjustment commands having normal priority.

[0050] This embodiment achieves natural decoupling of full-function remote control through physical division of labor between left and right hardware and protocol simulation of intelligent base stations, completely eliminating the drawbacks of traditional single-end devices that require frequent mode switching. Utilizing Bluetooth channel detection and multi-factor weight fusion algorithms, the system can accurately and automatically identify the left and right hands, and with a multi-level priority arbitration mechanism, effectively solves the problems of command conflicts and accidental touches. The device achieves plug-and-play functionality by simulating a standard USB HID device, providing extremely high compatibility and response speed without changing the TV interface, significantly improving the intelligence level of TV interaction and the smoothness of blind operation.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The calculation steps for the rotational bias score are as follows: within a preset sliding window, count the number of clockwise events and the number of counterclockwise events of the ring gyroscope angular velocity in the horizontal axis direction. Calculate the score using the ratio of the number of clockwise and counterclockwise events. If the score is greater than zero, it is determined that the ring is biased towards the right hand; if the score is less than zero, it is determined that the ring is biased towards the left hand. The steps for calculating the position score are as follows: establish a spatial coordinate system based on the base station reference axis, analyze the relative coordinates of the two rings projected onto the horizontal plane, and determine the orientation of the coordinates in combination with the human body midline, and determine the ring located on the right side of the human body midline as having right-hand characteristics. The steps for calculating the historical consistency score are as follows: a sliding voting algorithm is used to suppress accidental reversals and jumps within a preset time. The right-hand probability score is calculated by weighting and summing the rotational skewness score, the positional score, and the historical consistency score. When the probability score for the right hand is greater than the preset high threshold, the ring is determined to be worn on the right hand; when the score is between the preset low threshold and the high threshold, it is recorded as an uncertain state and the data is continuously observed until the data converges and the identity is automatically confirmed.

6. The dual-wearable, collaborative television remote control interaction method according to claim 4, characterized in that, It also includes instructions for arbitration and conflict resolution procedures: The smart base station monitors the trigger timestamps of the first operation signal from the left smart ring and the second operation signal from the right smart ring in real time. If the triggering time interval between the first operation signal and the second operation signal is greater than a preset time threshold, the smart base station will parse and report the corresponding TV remote control commands in the order of reception. If the triggering time interval between the first operation signal and the second operation signal is less than or equal to the preset time threshold, the smart base station determines that the current operation is a potential collaborative action and enters the collaborative instruction verification state. In the collaborative instruction verification state, if the reported signals of the two rings do not conform to the preset third operation signal gesture characteristics, the smart base station executes a unilateral instruction according to the preset priority weight.
