The energy storage device 5 is located at 1 o'clock to 5 o'clock in the annular cavity.

[0038] It should be noted that the first functional component can receive the user's operating instructions and transmit different signals to the user by interacting with the user, thereby realizing interaction with the user; and the second functional component is wirelessly connected to the external device, so that the user can operate the external device wirelessly connected to it through the first functional component, or obtain the information collected by the first functional component through the external device.

[0039] It is worth noting that the external device can be a host computer, a mobile phone, or other terminal devices.

[0040] It should also be noted that the energy storage device 5 is arranged at 1 o'clock to 5 o'clock in the annular cavity, and the first functional component and the second functional component are arranged at other positions in the annular cavity, making it more convenient for users to operate the smart wearable device.

[0041] The first functional component and the second functional component of the present application can be installed on a circuit board, or can be installed separately in an annular cavity.

[0042] The embodiment of the present invention forms an annular cavity for mounting a first functional component, a second functional component, and an energy storage device 5 through an inner ring 1 and an outer ring 2, and interacts with the user through the first functional component, wirelessly connects the second functional component to an external device, and electrically connects the energy storage device 5 to the first and second functional components, thereby providing electrical energy to the first and second functional components, and the energy storage device 5 is arranged at 1 o'clock to 5 o'clock in the annular cavity. The above disclosure is a smart wearable device that can not only interact with smart wearable devices through the first functional component, but also control an external device wirelessly connected to the second functional component through the first functional component, or obtain information collected by the first functional component through the external device.

[0043] Preferably, the energy storage device 5 is a lithium battery.

[0044] Specifically, the first functional component includes: an indicator light 31, an inertial sensor 32, a touch panel 33, an audio collection device 34, a vibration device 35 and a biometric information collection device 36;

[0045] The indicator light 31 is used to emit a light indication;

[0046] The inertial sensor 32 is used to measure the current posture and acceleration of the smart wearable device;

[0047] The touch panel 33 is used for operation;

[0048] The audio collection device 34 is used to collect the user's voice information;

[0049] The vibration device 35 is used to provide vibration feedback to the user;

[0050] The biometric information collection device 36 is used to collect the user's blood oxygen saturation and heart rate.

[0051] It should be noted that by providing an indicator light 31, the user can understand the current power level of the energy storage device 5 according to the indication of the indicator light 31, or understand the current status of the first functional component and / or the second functional component through the indicator light 31, such as the connection status of the second functional component with the external device, the standby state and working state of the first functional component, etc., and can also indicate whether the smart wearable device is in the power-on state or provide interactive feedback. The inertial sensor 32 is a sensor that can measure the three-dimensional posture and acceleration of an object. By providing the inertial sensor 32, different operations can be achieved by controlling the posture of the smart wearable device, thereby realizing the control of the external device connected to the second functional component or realizing the awakening of the smart wearable device.

[0052] The smart wearable device of the present application can also cooperate with the host computer (such as a mobile phone)'s own sensors for posture perception and perceive the host computer's posture.

[0053] By setting the touch panel 33, the user can wake up the smart wearable device through the touch panel 33, that is, switch the smart wearable device from low power consumption mode to high power consumption mode, and can synchronously control the host computer (such as mobile phone and other devices).

[0054] By providing the audio collection device 34 , the user can implement voice input through the audio collection device 34 , and can assist the inertial sensor in sensing the user's hand movements when necessary.

[0055] By setting up the vibration device 35, when the user operates the touch panel 33, feedback is provided through the vibration device 35, so that the user can distinguish whether the operation is successful. The vibration reminder can also be provided when the power of the energy storage device 5 is lower than the preset value, or as a reminder for other functions.

[0056] By setting up a biometric information collection device 36 for collecting the user's blood oxygen saturation and heart rate, the user can conveniently monitor his or her health status in real time, thereby protecting the user's health.

[0057] Preferably, the biometric information collection device 36 is a PPG sensor (photoplethysmography). A PPG sensor is a technology used to measure human physiological parameters, and can non-invasively monitor blood oxygen saturation and heart rate. The PPG sensor operates by using light emitted by an LED (such as red, infrared, or green light) to penetrate the skin and reach blood vessels. A photodetector then measures the reflected or transmitted light. These changes in light are related to blood flow, reflecting heart rate and blood oxygen levels.

[0058] Preferably, the inertial sensor 32 is a 6-axis inertial sensor, which can measure acceleration and angular velocity, and further measure the three-dimensional posture of the object by measuring acceleration.

[0059] Specifically, the indicator light 31 is set at the 10 o'clock to 11 o'clock position of the annular cavity;

[0060] It should be noted that the indicator light 31 can be set at the 10 o'clock position of the annular cavity, or at the 11 o'clock position, or between the 10 o'clock and 11 o'clock positions. Regardless of which position it is set at, it is convenient for the user to observe the indicator light 31.

[0061] It should also be noted that when the smart wearable device of the present application is worn on the left or right hand, the position of the indicator light 31 enables the user to more easily observe the prompt of the indicator light.

[0062] Specifically, the touch panel 33 is disposed at the 7 o'clock to 9 o'clock direction of the annular cavity and is located on one side of the annular cavity.

[0063] It should be noted that the touch panel 33 is arranged at the 7 o'clock to 9 o'clock direction of the annular cavity and is located on one side of the annular cavity, so that when the user wears it on the index finger, the user's thumb can easily touch it, thereby facilitating user operation.

[0064] Specifically, the audio collection device 34 is arranged at the 5 o'clock position of the annular cavity.

[0065] It should be noted that the audio collection device 34 is set at the 5 o'clock position of the annular cavity. When the user wears it on the index finger, the user raises the hand with the palm facing the mouth or covers the mouth to input voice.

[0066] It is worth noting that the audio collection device 34 can also collect audio without raising the hand, that is, voice input can be performed without the user raising the hand.

[0067] Specifically, the vibration device 35 is arranged at the 7 o'clock position of the annular cavity.

[0068] It should be noted that the vibration device 35 is set at the 7 o'clock position of the annular cavity, that is, after wearing, the vibration device 35 is near the fingertips, and when the vibration device 35 vibrates, it is convenient for the user to receive feedback from the vibration device 35 and ensure comfort.

[0069] Specifically, the biological information collection device 36 is disposed between the vibration device 35 and the audio collection device 34 .

[0070] It should be noted that the biometric information collection device 36 is set between the vibration device 35 and the audio collection device 34, so that the biometric information collection device 36 can collect the user's blood oxygen saturation and heart rate through the fingertips. Monitoring the user's blood oxygen saturation and heart rate through the fingertips can make the monitoring results more accurate.

[0071] Furthermore, the second functional component includes: a Bluetooth antenna 41 and an NFC device 42;

[0072] The Bluetooth antenna 41 is used for wireless communication with external devices;

[0073] The NFC device 42 is used to simulate a physical card to output data.

[0074] It should be noted that by setting up a Bluetooth antenna 41, a wireless communication connection with an external device can be established through the Bluetooth antenna 41, and the user's blood oxygen saturation and heart rate collected by the biometric information collection device 36 can be transmitted to the external device, and then the recognition algorithm can be processed by the external device.

[0075] It is worth noting that the Bluetooth antenna 41 can also transmit imu, mic, touch and other data.

[0076] Near Field Communication (NFC) is an emerging technology that enables devices (such as mobile phones) using NFC technology to exchange data when they are close to each other. It is an integration of contactless radio frequency identification (RFID) and interconnection technology. By integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chip, it can realize mobile payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other applications using mobile terminals.

[0077] Specifically, the Bluetooth antenna 41 is disposed at the 10 o'clock position of the annular cavity.

[0078] It should be noted that the Bluetooth antenna 41 is set at the 10 o'clock position of the annular cavity, so that when the user's palm is in different holding postures, the Bluetooth antenna 41 can be ensured to be in an outward state, effectively avoiding interference of human skin on the signal.

[0079] Specifically, the NFC device 42 is disposed in the annular cavity from 12 o'clock to 1 o'clock.

[0080] It should be noted that the NFC device 42 is set at the 12 o'clock to 1 o'clock direction of the annular cavity to facilitate users to use NFC to contact other devices (such as swiping an access card, etc.).

[0081] In order to facilitate understanding of the above solution, a further introduction is given below.

[0082] The smart wearable device of the present application is a ring structure, specifically a ring.

[0083] The ring is connected to a host computer (such as a mobile phone, computer, large screen, XR glasses, car, smart home, etc.). The ring and the host computer jointly perform data perception, feedback, and calculation, forming a complete interactive system.

[0084] Awakening the ring has two meanings: first, it switches from a low-power mode to a higher-power mode, corresponding to changes in sensor sampling rate, data transmission rate, MCU main control frequency, etc. Second, it awakens a function. The touch action itself is a prefix to the interaction action sequence and becomes part of the interaction.

[0085] The ring touchpad 33 wake-up method has the following advantages: 1) The touch location serves as the wake-up starting point, making it convenient and easy for users to use. 2) Touch is a natural part of interactive actions. 3) Touch sensing and other sensors collaborate to detect specific actions, reducing accidental touches.

[0086] After detecting a trigger signal, the ring combines it with specific data patterns from the ring and phone to identify different trigger actions, mapping them to different interactive functions. The ring's sensor placement and the integrated system make this triggering method and action more natural, convenient, and provide a better user experience.

[0087] The specific implementation method is as follows:

[0088] 1. The ring has a low power state and a high power state. The high power state has state 1, state 2, state 3, state 4, etc. In the low power state, the ring's sensor is in low power mode or sleep mode, and the Bluetooth antenna 41 is in a low power broadcast mode. A certain data pattern composed of touch, or a combination of touch and other sensor signals, is encoded as a specific wake-up method, corresponding to wake-up action 1, wake-up action 2, wake-up action 3, wake-up action 4, etc. When the wake-up mode is detected, the ring switches the power consumption from low power mode to the state corresponding to the wake-up mode. Turn on the high sampling rate data acquisition mode of the relevant sensors, collect the raw data and transmit it to the mobile phone host computer. The sensors here include but are not limited to touch chips, IMU (Inertial Measurement Unit, inertial sensor 32), microphones (i.e., audio acquisition device 34), PPG, etc.

[0089] 2. Once the wake-up pattern is detected, a time window is set. During this time window, the phone begins monitoring phone interface events and raw sensor data, and receives data transmitted by the ring. These two data types are then fused as wake-up data to detect subsequent specific wake-up actions. Raw data can include one or more of the following: a three-axis accelerometer, a three-axis gyroscope, a three-axis magnetometer, voice data, PPG data, ring touch chip event data or array coordinate data, or touch point trajectory data from the phone's touch screen. After the time window expires and there is no continuous data input, data collection ceases.

[0090] 3. The phone processes the wake-up data using a recognition algorithm. The algorithm consists of three steps: pre-processing, wake-up pattern classification, and post-processing. Pre-processing involves filtering and calibrating the raw data to remove high-frequency noise generated by sensors, map raw data from different hardware devices to a unified coordinate system, and align timestamps. Wake-up pattern classification uses a neural network algorithm to train a classifier to classify patterns in wake-up data from multiple sensors. The classification results output a specific wake-up action. Post-processing uses rules to aggregate and constrain the wake-up pattern results from different raw data and derive the final recognition results, improving the accuracy and robustness of gesture and / or voice pattern recognition. Post-processing includes rules for determining which sensor data features are included and excluded in the wake-up pattern, as well as the order and time intervals of the recognition results, enabling continuous action recognition and context modeling in pattern recognition. The advantage of this processing method is that the wake-up pattern is triggered by the user's natural wake-up action and behavior, and through the combined detection of multiple sensors, it prevents accidental touches. After recognition, a specific wake-up pattern is obtained, corresponding to a specific interactive function.

[0091] 4. After recognition, the ring and phone provide feedback that the user trigger mode has been activated, including but not limited to ring vibration, LED light, visual feedback on the phone interface, and sound feedback on the phone.

[0092] 5. After recognition, a specific wake-up pattern is obtained. Each wake-up pattern corresponds to a specific interactive function. The wake-up action is designed to follow the user's natural movements under the interactive function.

[0093] Specifically, the wake-up method is as follows:

[0094] 1) Trigger Action 1: Double-click the touchpad 33. Trigger Action 1 corresponds to State 1. After waking up, the ring enters State 1 from low-power mode. The sensor and Bluetooth wake up from low-power mode, remain active, and begin collecting and transmitting data corresponding to subsequent user actions to the phone via Bluetooth. The phone activates the interface and sensor monitoring state and begins collecting interface touch and sensor data. The ring sensor data and the phone sensor data are combined to determine the data mode.

[0095] 2) Trigger Action 2: Press touchpad 33, raise your hand, and speak. Data detection: After a long press on the touchpad, the IMU detects the hand-raised gesture, and the microphone detects the close-range voice signal. Trigger Action 2 corresponds to State 2, and the ring enters State 2 from other modes, entering voice interaction mode. The ring caches the user's voice signal, and data preprocessing is performed in the MCU. The processed voice data is transmitted via Bluetooth to a corresponding host computer, such as a mobile phone. Further voice recognition and other functions are performed in the mobile phone.

[0096] 3) Trigger Action 3: Raise your hand, place the ring against your lips, and speak. Data detection: After a long press on the touchpad, the microphone detects a close-range, whispered voice signal. Trigger Action 3 corresponds to State 3, where the ring enters Covert Voice Interaction Mode from any other mode. The ring caches the user's voice signal, and the MCU performs data preprocessing, including filtering for breath noise and gaining the voice signal. The processed voice data is then transmitted to the corresponding mobile phone via Bluetooth.

[0097] 4) Trigger Action 4: Place your thumb on the touchpad and use your index finger to draw on the host computer's touchpad 33 (e.g., a large screen). Data detection indicates a touchpad long press command and a touch command on the host computer's touchpad 33. Trigger Action 4 corresponds to State 4, and the ring enters State 4 from another mode. At this point, touch input on the touchpad 33 is treated as a separate data stream from the original touch interface, processed separately, and data mapped, adding a new mode of touch input to the host computer.

[0098] 6. For the above different trigger actions, the key modes that need to be identified in data processing include: 1) event recognition of single click, double click, and long press based on the touch chip, as well as the duration of the long press event. 2) Hand-raising action detection based on IMU data and realized by neural network algorithm. 3) Normal voice speech at medium distance, normal voice speech at close distance, and soft voice speech at close distance are comprehensively judged through breath sound perception and volume perception based on MIC data. 4) Touch screen touch signal input based on the host computer of a smartphone. Other similar data modes are non-critical modes and are processed as noise.

[0099] 7. Correspondingly, trigger action 1 corresponds to a double-click on the touch chip, and there are no other critical modes within the time window. Trigger action 2 includes a touchpad 33 long press event, a hand raise event, and a normal voice at close range, and there are no other critical times within the time window. Trigger action 3 includes a touchpad 33 long press event, a hand raise event, and a close range whisper event.

[0100] Trigger action 4 includes a long press event of the touch panel 33 and a touch signal input from the touch screen of the mobile phone.

[0101] 8. In touch mode, events for the ring touchpad 33 may not be included. However, they are included to reduce accidental triggering and improve accuracy. Firstly, the user's thumb touching the touchpad 33 is an intentional action, and secondly, the current ring design makes it very convenient for the thumb to touch the touchpad 33. The ring's microphone is positioned so that the mic port naturally aligns with the user's mouth during triggering actions 2 and 3, providing a convenient and natural experience.

[0102] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
