Description

Technical Field

[0001] This invention relates to the field of smart wearable devices and mobile terminal interaction technology, specifically to a smart ring and its matching terminal with magnetic charging and multi-functional interactive extension. Background Technology

[0002] Currently, with the rapid development of smart wearable devices, smart rings, as an emerging interactive terminal, are gradually attracting market attention. Existing technologies typically integrate functions such as health monitoring, gesture control, and notification reminders. However, most smart rings on the market (such as the Samsung Galaxy Ring) use a separate wireless charging dock for charging. Users need to periodically remove the ring and place it on the charging dock, separating the charging process from device usage. This charging method has the following drawbacks: firstly, the ring is small, making it easy for users to forget to charge, leading to depleted power and affecting the user experience; secondly, the ring is easily forgotten or lost after being removed, lacking an effective anti-loss mechanism.

[0003] Furthermore, the interaction between existing smart rings and device terminals mainly relies on wireless communication methods such as Bluetooth, resulting in relatively limited functionality. They cannot utilize physical contact to achieve more convenient extended functions such as identity authentication and posture sensing. Simultaneously, limited internal space in the ring forces large-capacity batteries to encroach on space for sensors, security chips, and other components, restricting functional expansion and making it difficult to strike a balance between miniaturization and multifunctionality. Regarding accessories, some users utilize magnetic ring clips to enhance grip stability or serve as supports; however, these accessories are standalone products, requiring additional carrying and installation, and lack charging and data interaction capabilities, resulting in poor usability.

[0004] Therefore, there is an urgent need for a smart ring and its supporting terminal that can integrate multiple functions such as magnetic charging, anti-loss reminders, identity authentication, and grip posture sensing to solve the problems existing in the current technology. Summary of the Invention

[0005] To address the problems mentioned in the background section regarding smart rings, this invention provides a smart ring and its accompanying terminal that feature magnetic charging and multi-functional interactive extensions.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A smart ring and its matching terminal featuring magnetic charging and multi-functional interactive extension, comprising the matching terminal and the smart ring;

[0008] The supporting terminal has a charging area on its rear shell, which includes a rear cover of the supporting terminal body and a protective shell detachably mounted on the rear cover of the supporting terminal body. The charging area includes a central strong magnet, a first annular electrode, and a second annular electrode. The central strong magnet is used for adsorption and positioning with the smart ring. The first annular electrode is arranged around the central strong magnet and serves as the positive charging electrode. The second annular electrode serves as the negative charging electrode and is arranged around the first annular electrode with insulation between them. The central strong magnet, the first annular electrode, and the second annular electrode form a concentric circle structure.

[0009] The main body of the smart ring is D-shaped, and the D-shaped main body has a planar segment. The planar segment is provided with a magnetic contact group corresponding to the charging area. The magnetic contact group includes a ring-end magnet and inner and outer ring electrodes. When the smart ring is magnetically attached to the charging area of ​​the back shell of the matching terminal, the inner and outer ring electrodes of the ring end maintain electrical contact with the first and second ring electrodes of the matching terminal at any rotation angle, thereby realizing charging.

[0010] By adopting the above technical solution, the charging area on the back shell of the supporting terminal uses concentric magnets and ring electrodes, combined with the planar segment and corresponding contact group on the D-shaped body of the smart ring, so that the ring can maintain stable electrical contact and physical adsorption with the supporting terminal at any rotation angle; the D-shaped planar structure prevents the ring from rolling, improves adsorption stability and directional recognition, and realizes the convenient experience of "adsorption is charging", eliminating users' anxiety about the battery life of the smart ring.

[0011] In a preferred embodiment, this application can be further configured such that: the central strong magnet of the supporting terminal is an electromagnet, and the supporting terminal adjusts the current of the electromagnet through a control system to change the attraction force.

[0012] By adopting the above technical solution, the central strong magnet of the supporting terminal is an electromagnet. Users or the system can dynamically adjust the magnitude of the adsorption force according to different usage scenarios (such as daily holding, support, removing rings, etc.), which not only ensures adsorption stability, but also makes it easy for users to remove rings, improving the flexibility and intelligence of use.

[0013] In a preferred embodiment, the smart ring may be further configured such that: the smart ring has a built-in small-capacity battery, and the smart ring also integrates one or more of the following: a health sensor array, a gesture recognition module, a touch panel, a vibration motor, and a security chip.

[0014] By adopting the above technical solution, magnetic charging is enabled anytime and anywhere. The smart ring can be equipped with a small-capacity battery, thereby freeing up valuable internal space for integrating various functional components such as a health sensor array, gesture recognition module, touch panel, vibration motor, and security chip. This ensures that the ring is thin and comfortable, while greatly expanding its functional integration capabilities and overcoming the contradiction between the function and size of traditional smart rings.

[0015] In a preferred embodiment, this application can be further configured such that: after the smart ring is attached to the back cover of the supporting terminal, the smart ring body serves as a support point, causing the supporting terminal to tilt and stand on the table, forming a horizontal or vertical screen stand.

[0016] By adopting the above technical solution, the smart ring can be attached to the back shell of the matching terminal, and its body can serve as a stable support point. By rotating the ring to adjust the support angle, the matching terminal can be tilted and placed on the table to form a horizontal or vertical screen stand. This function does not require additional accessories and improves the convenience of using the terminal in scenarios such as watching movies and making video calls.

[0017] In a preferred embodiment, this application can be further configured such that when the smart ring is attached to the back shell of the matching terminal, the smart ring serves as a gripping auxiliary anchor point to enhance grip stability and prevent drops.

[0018] By adopting the above technical solution, when the smart ring is attached to the back shell of the matching terminal, the user's finger makes physical contact with the ring. The ring acts as an auxiliary anchor point for gripping, increasing the friction and support point when gripping. It improves stability when gripping vertically and acts as a finger buckle when gripping horizontally, effectively reducing the risk of the device terminal slipping and enhancing grip safety and drop resistance.

[0019] In a preferred embodiment, this application can be further configured such that: the smart ring has a built-in health sensor, and when the smart ring is attached to the back shell of the supporting terminal, the health data is synchronized to the supporting terminal at high speed through the magnetic contact group.

[0020] By adopting the above technical solution, the smart ring has a built-in health sensor. When the ring is attached to the matching terminal, the health data is transmitted in a high-speed and stable wired synchronous manner through the magnetic contact group. Compared with the wireless transmission method, it is more efficient and reliable, avoids the delay or disconnection problems that may exist in Bluetooth transmission, and improves the real-time performance and accuracy of health data management.

[0021] The second objective of this invention is achieved through the following technical solution:

[0022] The smart ring and its associated terminal application have a two-way anti-loss method, which includes the following steps:

[0023] Detect the physical adsorption state between the smart ring and the matching terminal to obtain physical connection status information;

[0024] Detect the wireless communication connection status between the smart ring and the matching terminal, and obtain wireless communication status information;

[0025] When the physical adsorption state is detached, the wireless communication connection state is disconnected, and the duration of both detachment and disconnection exceeds a preset threshold, an anti-loss reminder is triggered.

[0026] The anti-loss reminder includes at least one of the following: the matching terminal sends a reminder that the ring has been forgotten, the smart ring sends a reminder that the matching terminal has been forgotten, or both send reminders simultaneously.

[0027] By adopting the above technical solution, the two-way anti-loss method combines the dual detection of physical adsorption status and wireless communication status. The reminder is only triggered when both are disconnected and the duration exceeds the threshold, effectively avoiding false alarms. At the same time, it covers two scenarios: forgetting the ring and forgetting the device terminal, realizing closed-loop anti-loss protection and improving the security of user devices.

[0028] The third objective of this invention is achieved through the following technical solution:

[0029] The smart ring and its associated terminal application employ a dual authentication method, which includes the following steps:

[0030] The smart ring has a built-in unique identification chip. When the smart ring and the matching terminal establish a physical connection authentication channel through the magnetic contact group, the first layer of ID authentication is performed.

[0031] After the first ID authentication is successful, the supporting terminal prompts the user to perform biometric authentication, which includes facial recognition or fingerprint recognition.

[0032] After successful biometric authentication, the terminal performs a full unlock or large-amount payment operation.

[0033] When the smart ring is lost, the accompanying terminal adds the smart ring's ID to the blacklist via remote command, thus invalidating the first layer of ID authentication. The accompanying terminal still allows for unlocking using biometric identification alone.

[0034] By adopting the above technical solution, the dual authentication method combines the physical contact ID authentication of the ring with biometric identification to build a multi-layered security system. After the ring is lost, the user can add the ring ID to the blacklist via remote command to disable its authentication, while the device terminal can still be unlocked using biometric identification alone. This ensures security and avoids the risk of the device terminal becoming unusable due to the loss of the ring, thus balancing security and convenience.

[0035] The fourth objective of this invention is achieved through the following technical solution:

[0036] The smart ring and its associated terminal application include a grip posture sensing and mode switching method, which comprises the following steps:

[0037] Detect the adsorption contact position of the smart ring on the back shell of the matching terminal;

[0038] When the adsorption contact position is located in the lower middle area of ​​the back shell of the accessory terminal, it is determined to be in a vertical grip state, and the accessory terminal automatically enters the one-handed mode or the keyboard shrinking mode.

[0039] When the adsorption contact position is located in the middle-side area of ​​the back cover of the accessory terminal, it is determined to be in a horizontal grip state, and the accessory terminal automatically enters landscape mode or game mode.

[0040] By adopting the above technical solution, the grip posture sensing and mode switching method automatically identifies the user's current grip posture (vertical or horizontal) by detecting the magnetic contact position of the ring on the back shell of the matching terminal, and triggers the matching terminal to switch to the corresponding operation mode (such as one-handed mode, minimized keyboard mode, landscape mode, or game mode). This interaction method does not require manual settings by the user, improving the convenience of operation and intelligent experience.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. The smart ring can be charged at any time while it is in an magnetic state by using the magnetic contacts on the back of the matching terminal. Users can charge the ring while holding the device, which solves the battery anxiety problem caused by the need to take the smart ring out and put it away for charging.

[0043] 2. Due to its convenient charging, the ring's built-in battery can be miniaturized, freeing up valuable internal space for integrating various functional components such as a health sensor array, gesture recognition module, touch panel, vibration motor, and security chip, achieving a high degree of unity between lightweight and multifunctionality;

[0044] 3. The ring also serves multiple functions, including a stand (for horizontal / vertical screen support), a grip anchor point (enhancing drop resistance and stability), a charger, and an identification key. Users do not need to purchase or carry separate accessories such as magnetic ring clips or stands, thus improving ease of use.

[0045] 4. By constructing a dual identity authentication mechanism through physical contact ID authentication and biometrics (face / fingerprint), the security of device unlocking and large-amount payments is improved. In the event of a lost ring, its ID can be remotely added to the blacklist, and the user can still use biometrics to unlock the device independently, avoiding the risk of the terminal becoming unusable due to the loss of accessories.

[0046] 5. Based on the magnetic contact position of the ring on the back shell of the terminal, it automatically recognizes the horizontal or vertical grip posture and triggers the terminal to automatically switch to landscape mode / game mode or one-handed mode / small keyboard mode, so as to achieve a seamless intelligent interactive experience.

[0047] 6. By combining physical adsorption status detection with wireless communication (such as Bluetooth) connection status detection, a two-way anti-loss mechanism is constructed; if the ring is not adsorbed back to the device terminal in time after being removed, the device terminal will issue an alert; when the device terminal is disconnected from the ring and is not in an adsorbed state, the ring will vibrate to remind the user that the device terminal may have been lost. It also supports a reverse search function to effectively prevent the ring and device terminal from being forgotten in both directions. Attached Figure Description

[0057] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0058] In one embodiment, such as Figure 1-5 As shown, this application discloses a smart ring and a matching terminal with magnetic charging and multi-functional interactive extension, specifically including: a smart ring 1 and a matching terminal 2;

[0059] Reference Figure 2 The supporting terminal 2 is an electronic product such as a mobile phone or tablet. The back cover 20 of the supporting terminal 2 has a charging area 21. The back cover 20 includes the back cover of the supporting terminal 2 body and a protective shell that can be detachably installed on the back cover of the supporting terminal 2 body. The charging area 21 includes a central strong magnet, a first ring electrode and a second ring electrode. The central strong magnet is used to attach and position with the smart ring 1. The first ring electrode is arranged around the central strong magnet and serves as the positive charging electrode. The second ring electrode serves as the negative charging electrode and is arranged around the periphery of the first ring electrode. An insulating layer is provided between the first ring electrode and the second ring electrode. The central strong magnet, the first ring electrode and the second ring electrode form a concentric circle structure.

[0060] Reference Figure 1 The main body of the smart ring 1 is D-shaped, and the D-shaped main body has a planar segment. The planar segment is provided with a magnetic contact group 10 corresponding to the charging area 21. The magnetic contact group 10 includes a ring end magnet and inner and outer ring electrodes. When the smart ring 1 is magnetically attached to the charging area 21 of the back shell 20 of the matching terminal 2, the inner and outer ring electrodes of the ring end maintain electrical contact with the first ring electrode and the second ring electrode of the matching terminal 2 at any rotation angle, so as to realize charging.

[0061] In actual use, the user aligns the flat section of the D-shaped smart ring 1 with the charging area 21 of the back shell 20 of the matching terminal 2. The central strong magnet attracts the magnet at the end of the ring, causing the ring to automatically attach and position itself. Since the first and second annular electrodes are concentric rings, the inner and outer annular electrodes can remain connected to the two annular electrodes at any rotation angle, thus achieving the convenient experience of "attachment for charging".

[0062] In this embodiment, the central strong magnet of the supporting terminal 2 can be an electromagnet; the supporting terminal 2 adjusts the current of the electromagnet through a built-in control system, thereby changing the attraction force.

[0063] In everyday holding scenarios, the system controls a small current output, providing moderate suction force so that users can easily remove the ring at any time. When users need to use the support function or enhance grip stability, the system automatically increases the current to improve suction force and ensure the ring is firmly attached. When users trigger the "Find Ring" function through the accompanying Terminal 2 App, the system can periodically change the current magnitude to make the ring vibrate or beep regularly to assist users in locating it.

[0064] Furthermore, the central strong magnet of the accessory terminal 2 is an electromagnet, and the magnitude of its attraction force is controlled by adjusting the duty cycle of the pulse width modulation (PWM) signal. The duty cycle refers to the proportion of the energized time within one cycle. The higher the duty cycle, the greater the average current of the electromagnet coil and the stronger the attraction force, and vice versa. The main control chip of the accessory terminal 2 can steplessly adjust the attraction force by directly changing the duty cycle value of the PWM signal output to the electromagnet drive circuit through software: when a smaller attraction force is needed so that the user can remove the ring at any time (such as in daily holding scenarios), the main control chip sets the duty cycle to a lower value (such as 20%~30%); when a larger attraction force is needed to ensure a firm attraction (such as when the accessory terminal 2 is supported by a desktop stand or in anti-loss scenarios), the main control chip sets the duty cycle to a higher value (such as 80%~100%). In this way, the accessory terminal 2 system can dynamically adjust the attraction force of the electromagnet according to different usage scenarios, taking into account both attraction stability and ease of retrieval.

[0065] In this embodiment, due to the ability to achieve magnetic charging anytime and anywhere, the smart ring 1 can be equipped with a small-capacity battery (e.g., 10-30mAh), thereby freeing up valuable internal space for integrating various functional components. The ring can integrate one or more of the following: a health sensor array (including heart rate sensor, blood oxygen sensor, accelerometer, body temperature sensor, etc.), a gesture recognition module (such as an IMU inertial measurement unit), a touch panel (such as a capacitive touch strip), a vibration motor, and a security chip (such as an SE security element).

[0066] When a user wears the ring, the health sensor can monitor health data such as heart rate, blood oxygen, steps, and sleep quality in real time; the gesture recognition module can recognize the user's pinch, rotate, and slide gestures, enabling remote control of the accompanying terminal 2 (such as taking photos, changing songs, answering phone calls, etc.).

[0067] Reference Figure 3-5 Once the smart ring 1 is attached to the back cover 20 of the companion terminal 2, the user can rotate the ring to the desired angle and use the ring itself as a support point to tilt the companion terminal 2 onto the table, forming a horizontal or vertical screen stand. For example, when the user needs to watch a video, the ring can be attached to the middle side of the back cover 20 of the companion terminal 2 and rotated to an appropriate angle, so that the companion terminal 2 stands stably on the table in a horizontal position. When the user needs to make a video call, the ring can be attached to the lower middle area of ​​the back cover 20 to form a vertical screen stand. This function eliminates the need to carry an additional companion terminal 2 stand, improving ease of use.

[0068] In this embodiment, when the smart ring 1 is attached to the back shell 20 of the supporting terminal 2, the user's finger makes physical contact with the ring. The ring acts as an auxiliary anchor point for gripping, enhancing grip stability and drop resistance. In the vertical grip position, the ring is located in the lower middle area of ​​the back shell 20 of the supporting terminal 2, and the user's little finger or ring finger can rest against the lower edge of the ring, increasing friction and providing a support point, reducing the risk of slipping. In the horizontal grip position, the ring is located in the middle-side area of ​​the back shell 20 of the supporting terminal 2, and the user's finger passes through the gap between the ring and the back shell 20, forming a "ring buckle" effect, further improving grip stability.

[0069] In this embodiment, the smart ring 1 incorporates built-in health sensors (such as heart rate sensors and blood oxygen sensors). When the smart ring 1 is attached to the back shell 20 of the accessory terminal 2, health data is synchronized to the accessory terminal 2 at high speed via a wired connection through the magnetic contact group 10. Compared to traditional Bluetooth wireless transmission, wired synchronization offers higher transmission rates and lower latency, and is unaffected by wireless signal interference. Users can view detailed health data analysis reports in real time on the accessory terminal 2, such as heart rate variability (HRV), blood oxygen saturation, and stress index. Simultaneously, the ring's charging process automatically completes data synchronization without requiring additional user intervention, enhancing the convenience of data management.

[0070] In one embodiment, a smart ring and its accompanying terminal feature magnetic charging and multi-functional interactive extensions, wherein the smart ring and its accompanying terminal employ a two-way anti-loss method. For example... Figure 6 As shown, this two-way anti-loss method includes:

[0071] S11: Detect the physical adsorption state between the smart ring and the matching terminal, and obtain physical connection status information;

[0072] In this embodiment, the physical adsorption state refers to the direct physical contact and electrical connection established when the smart ring is attracted to the central strong magnet in the charging area of ​​the matching terminal's back cover through the magnetic contact group on its planar segment. This state is determined by detecting the level signal between the charging contacts or by detecting the Hall sensor signal in the magnetic circuit. When the ring is adsorbed onto the matching terminal's back cover, the system obtains the "adsorbed" physical connection state information. When the ring is removed from the matching terminal's back cover, the system obtains the "detached" physical connection state information.

[0073] Specifically, the charging management chip inside the supporting terminal continuously monitors the voltage or current changes on the charging area contacts; when the ring is attracted, the contacts are short-circuited or a charging circuit is formed, and the chip detects a certain level value, which is determined to be the "attracted state"; when the ring is removed, the circuit is broken, the level value returns to zero, and it is determined to be the "detached state"; this status information is reported to the supporting terminal main control system in real time, as the first basis for anti-loss judgment.

[0074] S12: Detect the wireless communication connection status between the smart ring and the matching terminal, and obtain wireless communication status information;

[0075] In this embodiment, the wireless communication connection status refers to the wireless connection status established between the smart ring and the matching terminal through the Bluetooth Low Energy communication protocol; this status reflects whether the ring and the matching terminal are within the effective wireless communication range (usually within 10 meters); when the two are successfully paired and maintain heartbeat packet interaction, the status is "connected"; when the signal is interrupted or out of range, and the heartbeat packet times out without response, the status is "disconnected".

[0076] Specifically, the ring integrates a low-power Bluetooth module. After the initial pairing with the paired terminal, the two will periodically exchange connection-keeping signals. The application (App) of the paired terminal will listen for connection status callbacks from the Bluetooth protocol stack. If the ring continues to move away from the paired terminal until it can no longer receive query signals from the paired terminal, the Bluetooth link will be disconnected due to timeout, and the system will record the wireless communication status as "disconnected". This status information is monitored independently and in parallel with the physical adsorption status.

[0077] S13: When the physical adsorption state is detached and the wireless communication connection state is disconnected, and the duration of both detachment and disconnection exceeds a preset threshold, an anti-loss reminder is triggered.

[0078] In this embodiment, the preset threshold is a time length that is set by the system default or defined by the user. Its purpose is to prevent frequent false alarms caused by momentary signal loss or the user temporarily removing the ring (such as washing hands). The typical threshold can be set to 30 seconds to 2 minutes. Only when the ring is physically removed from the matching terminal and the Bluetooth connection is also disconnected, and both of these states continue for more than the threshold, will the system determine it as a real "potential loss" event, rather than a temporary operation by the user.

[0079] Specifically, assuming a preset threshold of 1 minute; when a user removes the ring and places it on their desk, then takes the accompanying terminal to the meeting room, at this point: the physical adsorption state immediately changes to "detached," and as the user moves away, the Bluetooth connection also changes to "disconnected." The timer inside the accompanying terminal system starts counting and continuously monitors these two states; if the user returns and re-adsorbs the ring or reconnects via Bluetooth within 1 minute, the timer resets to zero, and no alert is triggered; if more than 1 minute has passed and the two states have not been restored, the system determines that the ring has left the user's control (forgotten) and immediately triggers the anti-loss alert logic.

[0080] S14: The anti-loss reminder includes at least one of the following: the matching terminal sends a ring-forgotten reminder, the smart ring sends a matching terminal-forgotten reminder, or both send reminders simultaneously;

[0081] In this embodiment, the anti-loss reminder is a warning method that notifies the user through sound, light, and electricity, and it is bidirectional; the "ring-forgot reminder issued by the accessory terminal" is intended to prevent the ring from being lost alone; the "accessory terminal-forgot reminder issued by the smart ring" is intended to prevent the accessory terminal from being forgotten; both can be triggered simultaneously to achieve closed-loop protection.

[0082] Specifically, the accessory terminal issues a ring-forgotten reminder: When the accessory terminal determines that the ring may be lost, it immediately plays a preset warning sound through its built-in speaker (such as "Please check if you are wearing the ring") or pops up a window on the accessory terminal screen to indicate "The ring may have been lost," and records the current GPS location for the user to trace back and find; The smart ring issues an accessory terminal-forgotten reminder: This logic is determined independently on the ring; When the ring detects that its physical adhesion has failed and the Bluetooth disconnection exceeds a threshold, the microcontroller inside the ring drives the vibration motor to generate intermittent strong vibrations or drives the buzzer to emit a high-frequency beeping sound, reminding the user that the accessory terminal may have been forgotten somewhere, and to take the ring back to find it; Both issue reminders simultaneously: In the most risky scenarios (such as when the two are far apart and both are stationary for a long time), the accessory terminal and the ring will each perform the above reminder actions to maximize the user's attention.

[0083] The two-way anti-loss method can accurately distinguish between scenarios where the user actively removes the ring and scenarios where it is truly forgotten or lost, effectively avoiding false alarms and missed alarms, and achieving two-way security protection for the smart ring and its matching terminal.

[0084] In one embodiment, a smart ring and its accompanying terminal feature magnetic charging and multi-functional interactive extensions, wherein the smart ring and its accompanying terminal employ a dual authentication method. For example... Figure 7 As shown, this dual authentication method includes:

[0085] S21: The smart ring has a built-in unique identification chip. When the smart ring and the matching terminal establish a physical connection authentication channel through the magnetic contact group, the first layer of ID authentication is performed.

[0086] In this embodiment, the unique identification chip refers to a security chip pre-programmed with a globally unique identifier (UID). This identifier is written at the factory and cannot be tampered with, serving as an electronic ID card to distinguish different smart rings. The physical connection authentication channel refers to the wired electrical connection path established between the smart ring and the matching terminal through a magnetic contact group. This path is not only used for charging and data transmission, but also serves as a trust channel for identity authentication.

[0087] Specifically, the smart ring integrates an SE security chip that meets or exceeds the EAL4+ security level. This chip stores a unique ID bound to the ring. When the ring's D-shaped flat section is attached to the charging area of ​​the matching terminal's back cover, the ring electrode on the ring end establishes stable electrical contact with the ring electrode on the matching terminal. The matching terminal's main control chip sends an authentication request command to the ring through this physical channel. The security chip on the ring responds and returns its unique ID. The matching terminal compares this ID with its locally stored list of authorized IDs: if a match is found, the first layer of ID authentication is successful; if a match fails, further operation is rejected, and the matching terminal screen displays "Unauthorized Ring." This authentication process is completed within milliseconds, imperceptibly to the user.

[0088] S22: After the first ID authentication is successful, the supporting terminal prompts the user to perform biometric authentication, which includes facial recognition or fingerprint recognition.

[0089] In this embodiment, biometric authentication refers to liveness detection technology based on the user's physiological characteristics as a second layer of identity verification factor; facial recognition uses the front-facing camera and 3D structured light module of the supporting terminal to collect facial depth information, and fingerprint recognition uses the fingerprint module under the screen or on the side of the supporting terminal to collect fingerprint features; this step ensures that the operator is the legitimate user of the ring, and not someone else who merely holds the ring.

[0090] Specifically, after the first layer of ID authentication is successful, the supporting terminal system automatically wakes up the biometric module and pops up a prompt box on the screen interface, such as "Please verify your face to complete the unlock" or "Please press the fingerprint sensing area"; the user follows the prompts to align their face or press their finger; the supporting terminal compares the collected biometric features with the pre-entered template, and the comparison algorithm runs in TEE (Trusted Execution Environment) to ensure security; only if the comparison passes, the biometric authentication is successful; if it fails multiple times in a row, the system will enter a cooling-off period or require the user to enter a backup password.

[0091] S23: After successful biometric authentication, the terminal performs a full unlock or large-amount payment operation;

[0092] In this embodiment, full unlocking refers to unlocking the screen of the terminal and granting full access to all applications and data, which is different from shallow unlocking that only allows viewing notifications; large-amount payment operations refer to mobile payment transactions that exceed a preset amount threshold (such as 200 RMB), which require strong identity verification according to financial security regulations; after successful dual authentication, the system grants high-security-level operation permissions.

[0093] Specifically, when a user attaches the ring to the paired terminal and completes facial recognition, the terminal determines that both "possessing an authorized ring" and "operating on behalf of the user" are met, and directly accesses the main screen without requiring additional swiping or password input. For payment scenarios: when a user initiates a transfer exceeding 200 yuan, the payment application calls a security interface, requiring the system to complete two-factor authentication. If the ring is already attached and the ID verification is successful, the user only needs to confirm with their fingerprint once to complete the payment, without having to re-enter the payment password. The system will also record the time of two-factor authentication, the ring ID, and the biometric identification method in the security log for subsequent auditing.

[0094] S24: When the smart ring is lost, the supporting terminal adds the ID of the smart ring to the blacklist via remote command, thereby invalidating the first layer of ID authentication. The supporting terminal still allows the use of biometric identification to unlock the device independently.

[0095] In this embodiment, a remote command refers to a secure operation command issued by the user after logging into the same account through another trusted device (such as a backup mobile phone, tablet, or web-based cloud service); the blacklist is a list of denied authorizations maintained locally on the supporting terminal and stored in a secure area. The ring ID in the list will be ignored by the system and will not pass the first layer of authentication; this mechanism ensures that the lost ring cannot be used by others to unlock the user's supporting terminal or complete payments, while the user's supporting terminal itself is not affected.

[0096] Specifically, after discovering their ring is lost, users can immediately take any of the following actions: Log in to the cloud service website provided by the compatible terminal manufacturer, find the lost ring in the "Device Management - Security Accessories" list, and click "Report Lost" or "Add to Blacklist"; Use another tablet logged into the same account to remotely report the ring lost in the compatible app; The remote command is sent to the user's compatible terminal through an encrypted channel, and the compatible terminal writes the lost ring's ID to the local security blacklist upon receiving the command; Subsequently, no matter who attempts to authenticate with the ring, the compatible terminal will fail the first ID comparison due to matching the blacklist and record an abnormal attempt; At the same time, the compatible terminal fully retains its biometric unlocking function: users can still use facial recognition or fingerprint to unlock the compatible terminal, complete small payments, make and receive calls, etc.; If the user later finds the ring, they can perform the "Unreport Lost" operation through the same path to remove the ID from the blacklist and restore full functionality; If the ring is confirmed to be unrecoverable, the user can also delete the ring's authorization record on the compatible terminal, making the ring permanently invalid.

[0097] The dual authentication method achieves the design goal of being both secure and flexible: dual protection enhances security during daily use; users experience no anxiety if the ring is lost, and the associated terminal functions remain unaffected.

[0098] In one embodiment, a smart ring and its accompanying terminal, featuring magnetic charging and multi-functional interactive extensions, are provided. The smart ring and terminal utilize a grip posture sensing and mode switching method. For example... Figure 8 As shown, the grip posture sensing and mode switching method includes:

[0099] S31: Detect the adsorption contact position of the smart ring on the back shell of the matching terminal;

[0100] In this embodiment, the adsorption contact position refers to the specific coordinate area corresponding to the center of the ring when the D-shaped planar segment of the smart ring establishes a magnetic connection with the charging area of ​​the back shell of the matching terminal. This position is sensed by a contact sensor array or capacitive position detection unit arranged around the charging area of ​​the back shell of the matching terminal. Due to the magnetic properties of the ring, it can accurately adsorb within the concentric circle structure of the charging area each time. By detecting the conduction combination of the ring with electrodes at different positions, the system can deduce the relative installation position of the ring on the back shell of the matching terminal.

[0101] Specifically, the charging area on the back cover of the accessory terminal is not limited to a single point, but rather consists of multiple discrete concentric circular charging areas distributed along the central axis of the back cover (for example, a main charging area is located in the lower part of the back cover, and another charging area is located on the side of the middle part). Each charging area is equipped with an independent central magnet, a ring electrode, and a position encoding pin. When the ring is attracted to a certain charging area, the corresponding position detection pin is shorted or a specific level signal is generated. The main control chip of the accessory terminal collects the signal status of each position pin through analog-to-digital conversion (ADC), and combined with a preset coordinate mapping table, can uniquely determine the ring's attraction position coordinates (x, y) with an accuracy of millimeters. In addition, multiple Hall sensors can be arranged around the charging area to calculate the position by utilizing the difference in the magnetic field strength distribution of the ring's magnet. This position detection process is completed the moment the ring is attracted (within approximately 50 milliseconds) and is continuously monitored. If the user moves the ring during use, the system updates the position information in real time.

[0102] S32: When the adsorption contact position is located in the lower middle area of ​​the back shell of the supporting terminal, it is determined to be in a vertical grip state, and the supporting terminal automatically enters the one-handed mode or the keyboard shrinking mode.

[0103] In this embodiment, the vertical grip refers to the user's posture of holding the terminal with one hand, the terminal screen facing the user's face, and the terminal's length direction being basically perpendicular to the horizontal plane; the lower middle area refers to the strip-shaped area extending along the length of the terminal's back cover from slightly below the geometric center to near the bottom edge of the terminal (for example, for a 6.7-inch terminal, this area is approximately 120mm to 160mm from the top of the terminal); this area is precisely where the little finger or ring finger naturally rests when the user holds the terminal vertically; the one-handed mode refers to an interaction mode in which the content displayed on the terminal screen is compressed inwards, so that the control elements in the upper half of the screen fall within the reach of the thumb; the reduced keyboard mode refers to a keyboard layout in which the input method keyboard is shifted to one side of the screen and reduced in size to facilitate one-handed typing.

[0104] Specifically, the accompanying terminal system monitors the ring's magnetic position coordinates in real time. When the system determines that the ordinate (Y value) of the ring's center is greater than a preset first threshold (e.g., Y > 120mm, with the top of the terminal as the origin and downward as positive), and the lateral (X value) is within ±15mm of the terminal's width center, it is determined to be in a vertical grip state. At this time, the system automatically performs the following operations: Enable one-handed mode: If the user previously enabled the "Automatic Ring Magnification Switching Mode" option in the system settings, the system will shrink the screen display content to the lower left or right corner according to a preset ratio (e.g., 70%) (based on the user's dominant hand setting), and simultaneously move the navigation buttons such as Back, Home, and Multitasking down, so that the user's thumb does not need to move to the bottom center of the screen to complete the operation; Switch to zoom-out button. Keyboard: When a user focuses on the input box to bring up the keyboard, the keyboard appears as a floating keypad by default and attaches to the lower left or right corner of the screen. The keyboard size is reduced to 60% of the standard size, and the key spacing is adjusted accordingly to accommodate thumb taps. Users can slide on the drag bar at the top of the keyboard to adjust its precise position. Additional optimizations: The system can also improve touch sensitivity to be compatible with screen protectors and expand the notification bar pull-down response area to further optimize the one-handed operation experience. If users do not wish to switch automatically, they can click "Do not switch" or "Do not remind again" in the pop-up floating prompt box, and the system will record user preferences.

[0105] S33: When the adsorption contact position is located in the middle of the side area of ​​the back shell of the supporting terminal, it is determined to be in a horizontal grip state, and the supporting terminal automatically enters the landscape mode or game mode.

[0106] In this embodiment, the horizontal grip refers to the user holding the terminal with both hands, with the long side of the terminal screen horizontal and the short side vertical, similar to the posture of holding a game controller or watching a video; the middle-side area refers to the side area located slightly to the left or right of the geometric center of the terminal along the width direction of the terminal's back cover, while the vertical coordinate is located in the middle of the height direction of the terminal (for example, the horizontal coordinate X < 15mm or X > terminal width - 15mm, and the vertical coordinate Y is between 40mm and 120mm); this area is exactly where the index or middle finger naturally rests when the user holds the terminal horizontally; landscape mode refers to the application interface being rotated 90 degrees to present a horizontal layout, suitable for scenarios such as video playback and slideshow browsing; game mode refers to a specific operating environment in which the system automatically allocates more CPU / GPU resources to the current game, blocks notification pop-ups, locks screen brightness, and optimizes network latency.

[0107] Specifically, the accompanying terminal system continuously monitors the ring's magnetic position coordinates. When the system determines that the horizontal coordinate (X value) of the ring's center is less than the preset second threshold (X < 15mm, left-side grip) or greater than the width of the accompanying terminal minus the third threshold (X > the width of the accompanying terminal - 15mm, right-side grip), and the vertical coordinate is in the middle range (40mm < Y < 120mm), it is determined to be in a horizontal grip state. At this time, the system automatically performs the following operations: Trigger landscape switching: The system broadcasts a landscape mode switching signal. After receiving the signal, if the foreground application supports landscape layout (such as video apps, photo albums, and some games), it will automatically rotate to landscape display. If the current application does not support landscape (such as social apps that scroll through information feeds vertically), the system will maintain the portrait mode but pop up a manual rotation prompt. Enable game mode: If the system detects that the foreground application belongs to the game category (judged by the application package name or foreground process type), it will automatically enable game mode. After exiting the horizontal grip state (the ring is removed or moved to a non-horizontal grip area), the system automatically restores the original mode settings.

[0108] The grip posture sensing and mode switching method requires no manual settings from the user. It can intelligently recognize the grip posture and switch to the most suitable matching terminal mode simply by the natural adsorption position of the ring, improving the convenience of operation and intelligent experience. This method is particularly suitable for high-frequency scenarios such as quickly unlocking the phone to reply to messages with one hand, watching movies in landscape mode during commutes, and starting a game during short breaks.

[0109] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present invention, such design should fall within the protection scope of the present invention.
