Description

Technical Field

[0001] This invention relates to the field of smart rings, and particularly to a smart ring and an interaction method based thereon, a smart glasses component, and a computer-readable storage medium. Background Technology

[0002] In the present technology, smart rings usually have mechanical buttons or capacitive touch buttons on the ring body to realize human-computer interaction and remote control of smart glasses. However, these buttons usually only support tapping operations, and the buttons need to be tapped in a specific position to be triggered. Furthermore, the buttons need to be rotated to the fingertip to tap the buttons with one hand, which makes human-computer interaction inconvenient and affects the user experience. Summary of the Invention

[0003] The main objective of this invention is to propose an interaction method based on a smart ring, which aims to increase the coverage area of ​​the sensing area on the ring body, enrich the design and operation freedom of touch operation, and thus improve the convenience of human-computer interaction of the smart ring.

[0004] To achieve the above objectives, the interaction method based on a smart ring proposed in this invention includes the following steps:

[0005] Electrical signals are acquired by an elastic wave sensor configured on the body of the smart ring.

[0006] The touch operation received by the ring body is identified based on the electrical signal;

[0007] Control commands are sent to the smart glasses that are wirelessly connected to the smart ring based on the touch operation.

[0008] Optionally, the touch operation includes a single click, a double click, and / or a swipe.

[0009] Optionally, the step of identifying the touch operation received by the ring body based on the electrical signal includes: identifying the touch operation received by the ring body based on the number of electrical signals within a first time interval.

[0010] Optionally, the elastic wave sensor includes a first elastic wave sensor and a second elastic wave sensor spaced apart along the circumferential direction of the ring body. The step of identifying the touch operation received by the ring body based on the electrical signal includes: acquiring the start signal and end signal of the first electrical signal of the first elastic wave sensor and the second electrical signal of the second elastic wave sensor, respectively; identifying the direction of sliding received by the ring body based on the time sequence, time difference, and / or intensity difference between the start signal of the first electrical signal and the start signal of the second electrical signal, and the time sequence, time difference, and / or intensity difference between the end signal of the first electrical signal and the end signal of the second electrical signal.

[0011] Optionally, if the starting signal of the first electrical signal is prior to the starting signal of the second electrical signal, and / or the time difference between the starting signals of the first and second electrical signals is a positive time difference, and / or the intensity difference between the starting signals of the first and second electrical signals is a positive intensity difference, and the last signal of the first electrical signal is prior to the last signal of the second electrical signal, and / or the time difference between the last signal of the second and first electrical signals is a positive time difference, and / or the intensity difference between the last signal of the second and first electrical signals is a positive intensity difference, then it is determined that the ring body is subject to sliding along the first direction; otherwise, it is determined that the ring body is subject to sliding along the second direction; the second direction is opposite to the first direction.

[0012] Optionally, the interaction method based on the smart ring further includes the step of detecting the wearing direction of the smart ring by means of a wearing direction detection device configured on the ring body.

[0013] Optionally, the wearing direction detection device includes a first detection element and a second detection element disposed on the inner side of the ring body, the first detection element and the second detection element being spaced apart along the axial direction of the ring body; the step of detecting the wearing direction of the smart ring by means of the wearing direction detection device disposed on the ring body includes: acquiring a first trigger signal of the first detection element and a second trigger signal of the second detection element; when the time sequence of the first trigger signal is before the time sequence of the second trigger signal, determining that the wearing direction is positive; when the time sequence of the first trigger signal is after the time sequence of the second trigger signal, determining that the wearing direction is negative.

[0014] Optionally, both the first detection element and the second detection element are configured as capacitive sensors or pressure sensors.

[0015] Optionally, the outer peripheral surface of the ring body is provided with guide marks for indicating the wearing direction.

[0016] The present invention also proposes a smart ring, comprising: a ring body, an elastic wave sensor, a controller, a wireless communication module, and a memory. The elastic wave sensor is disposed on the ring body, and the memory stores an interactive program based on the smart ring that can run on the controller. When the interactive program based on the smart ring is executed by the controller, it implements the steps of the aforementioned interactive method based on the smart ring.

[0017] The present invention also proposes a smart glasses assembly, including smart glasses and the aforementioned smart ring.

[0018] The present invention also proposes a computer-readable storage medium storing an interactive program based on a smart ring, wherein the interactive program based on the smart ring, when executed by a controller, implements the steps of the aforementioned interactive method based on a smart ring.

[0019] The technical solution of this invention replaces traditional mechanical buttons or capacitive touch buttons with an elastic wave detection and control component, increasing the coverage area of ​​the sensing area on the smart ring. Touch operations performed by the user on any area of ​​the ring body can be detected and recognized, enabling one-handed operation even when the elastic wave sensor is not located on the fingertip. This improves the convenience of human-computer interaction and enhances the ease of remotely controlling smart glasses via the smart ring. Secondly, changes in the elastic wave signal accurately identify various types of touch operations, such as single clicks, double clicks, or swipes, enriching the design and freedom of touch operations and thus improving the flexibility of the smart ring. Furthermore, since the elastic wave sensor can be applied to rigid structural components made of conductive or non-conductive materials, it avoids material limitations on the smart ring, making the technical solution applicable to a wide range of scenarios.

[0034] This invention provides a smart ring and an interaction method based on the smart ring. Please refer to... Figure 6 , Figure 6This is a schematic diagram of the smart ring structure of the hardware operating environment involved in the embodiment of the present invention. The smart ring may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard. Optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0035] Those skilled in the art will understand that Figure 6 The structure shown does not constitute a limitation on the smart ring and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0036] like Figure 6 As shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a smart ring control program. Figure 6 In the smart ring shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and memory 1005 in the smart ring of the present invention can be set in the smart ring. The smart ring calls the smart ring-based interaction program stored in the memory 1005 through the processor 1001 (i.e., controller) and executes the smart ring-based interaction method provided in the embodiment of the present invention.

[0037] Please refer to Figures 1 to 3 In one embodiment of the present invention, the smart ring 10 includes:

[0038] Ring body 11;

[0039] An elastic wave detection and control component includes an elastic wave sensor 12 and a controller electrically connected to each other. The elastic wave sensor 12 is disposed on the ring body 11, and the controller is used to identify touch operations received by the ring body 11 based on the electrical signals generated by the elastic wave sensor 12; and

[0040] The wireless communication module is electrically connected to the controller, which in turn wirelessly connects to the smart glasses to control the working status of the smart glasses based on touch operations.

[0041] Without loss of generality, an elastic wave is a wave that propagates in a rigid structure (i.e., a hard object), and the elastic wave sensor 12 can convert the detected elastic wave signal into an electrical signal. Compared to other sensors, the elastic wave sensor 12 has many advantages. For example, the elastic wave sensor 12 is not affected by the conductivity of the material, and can support both non-conductive materials (such as glass, plastic, or wood) and conductive materials (such as metals or graphene); furthermore, the elastic wave sensor 12 has low power consumption, no radiation, and strong anti-interference ability. Specifically, the elastic wave sensor 12 includes, but is not limited to, piezoelectric sensors and strain sensors, wherein the piezoelectric sensors include, but are not limited to, piezoelectric ceramics, piezoelectric crystals, and piezoelectric thin films.

[0042] Specifically, the smart ring 10 typically includes many rigid structural components, such as the ring body 11 and a circuit board located within the ring body 11. When a user touches the ring body 11, it generates tiny fluctuations. These fluctuations propagate along the smart ring 10 as elastic waves and are captured by the elastic wave sensor 12. The elastic wave sensor 12 then converts the captured elastic wave signal into an electrical signal and transmits it to the controller. The controller can then recognize the user's touch operation and remotely control the smart glasses to execute corresponding operation commands via the wireless communication module. It can be understood that the elastic waves generated by the touch operation can still be captured by the elastic wave sensor 12 after propagating a considerable distance along the smart ring 10. This means that the touch operation area sensed by the elastic wave sensor 12 can essentially cover the entire ring body 11.

[0043] The technical solution of this invention uses an elastic wave detection and control component to replace traditional mechanical buttons or capacitive touch buttons, which increases the coverage area of ​​the sensing area on the smart ring 10. Touch operations performed by the user in any area of ​​the ring body 11 can be detected and recognized, enabling one-handed operation for tapping or swiping even when the elastic wave sensor 12 is not located on the fingertip. This improves the convenience of human-computer interaction for the smart ring and enhances the ease of remotely controlling smart glasses via the smart ring. Secondly, by accurately identifying various types of touch operations, such as single clicks, double clicks, or swipes, changes in the elastic wave signal enrich the design and freedom of touch operation, thereby improving the flexibility of the smart ring. Furthermore, since the elastic wave sensor 12 can be applied to rigid structural components made of conductive or non-conductive materials, it avoids material limitations on the smart ring 10, making the technical solution applicable to a wide range of scenarios.

[0044] It should be noted that the smart glasses in the embodiments of the present invention include, but are not limited to, VR (Virtual Reality) glasses, AR (Augmented Reality) glasses, MR (Mediated Reality) glasses, or Bluetooth audio glasses. Taking AR glasses as an example, the working state of the smart glasses is controlled by touch operations, including but not limited to controlling the working state of different functional components of the smart glasses and controlling different functional applications of the smart glasses. Functional applications include controlling applications, such as switching between different interfaces or different applications within the same application. Functional components include, but are not limited to, speakers, cameras, and optical engines; for example, a single click to turn the speaker off, a double click to turn the speaker on, and a swipe to adjust the speaker volume. It is understood that the technical solution of the present invention does not specifically limit the correspondence between touch operations and working states; those skilled in the art can arbitrarily combine and adjust them according to actual design requirements.

[0045] It is worth mentioning that, optionally in this embodiment of the invention, the electrical signal is determined to be a valid electrical signal and the next control command is triggered only when the intensity value of the electrical signal generated by the elastic wave sensor 12 is greater than or equal to a first preset intensity value. This reduces the risk of false triggering, such as the vibration sensed by the elastic wave sensor 12 when a fist is accidentally clenched and lightly touched by the smart ring 10. It is understood that those skilled in the art can set specific first preset intensity values ​​according to the product structure of different smart rings 10 and the arrangement of the elastic wave sensors 12.

[0046] Please refer to Figure 3 In some embodiments, the ring body 11 has a mounting cavity, and the elastic wave sensor 12 is fixed to the cavity wall. This provides good protection for the elastic wave sensor 12 and enables it to capture elastic wave signals with higher energy, thereby improving the response sensitivity to touch operations. Optionally, in this embodiment, the elastic wave sensor 12 is adhered to the cavity wall by an adhesive layer structure 15 to facilitate its installation and fixation.

[0047] Of course, in other embodiments, the elastic wave sensor 12 may also be mounted on other rigid structural members, for example, please refer to Figure 4 The elastic wave sensor 12 is mounted on a circuit board, which is fixed to the cavity wall of the mounting cavity. Specifically, in this embodiment, the circuit board optionally includes a rigid circuit board 13 with a controller and a flexible circuit board 14 electrically connected to the rigid circuit board 13. The elastic wave sensor 12 is mounted on the flexible circuit board 14, which is fixed to the cavity wall of the mounting cavity. Of course, please refer to... Figure 5In other embodiments, the circuit board may be configured as a rigid circuit board 13, with both the controller and the elastic wave sensor 12 disposed on the rigid circuit board 13, which is fixed to the cavity wall of the mounting cavity.

[0048] Please refer to Figure 1 In some embodiments, the smart ring 10 further includes a power supply battery 16 disposed on the ring body 11. The power supply battery 16 is electrically connected to the controller, so that the smart ring 10 can be freed from the constraints of a power cord, thereby making it convenient for the user to wear and use. Optionally, in this embodiment, the power supply battery 16 is configured as a rechargeable battery. Of course, in other embodiments, the power supply battery 16 may not be provided, and the power supply to the elastic wave sensor 12 and the controller and other electrical components may be achieved through a charging interface or a power cord.

[0049] In some embodiments, the power supply battery 16 is disposed within the mounting cavity, and the power supply battery 16 and the elastic wave sensor 12 are spaced apart in the circumferential direction of the ring body 11. This maximizes the space utilization of the mounting cavity and facilitates the assembly of the power supply battery 16 and the elastic wave sensor 12. Optionally, in this embodiment, the power supply battery 16 is arc-shaped to allow for a larger volume and thus greater energy storage capacity. However, this design is not limited to this; in other embodiments, the ring body 11 may be an open ring, with the two ends of the power supply battery 16 abutting against the open ends of the ring body 11, so that the smart ring 10 forms a closed ring.

[0050] In some embodiments, multiple elastic wave sensors 12 are provided, and the multiple elastic wave sensors 12 are arranged at intervals in the circumferential direction of the ring body 11. Specifically, optionally, two, three, or even more elastic wave sensors 12 may be configured, and those skilled in the art can determine the number and position of the elastic wave sensors 12 according to design requirements. In this way, the sliding direction can be identified more quickly and accurately, and the ring body 11 can also have multiple touch operation sensing areas, thereby enriching the combination of touch operation and working state correspondence, so as to realize richer and more complex human-computer interaction. Of course, in other embodiments, there may be only one elastic wave sensor 12.

[0051] It is worth mentioning that a single elastic wave sensor 12 can also detect sliding operations. For example, the ring body 11 has a continuous plane, and the elastic wave sensor 12 is located at one end of the continuous plane. If the finger slides from one end of the continuous plane to the other end, the elastic wave intensity captured by the elastic wave sensor 12 gradually increases, and an electrical signal with gradually increasing intensity is generated. If the finger slides from the other end of the continuous plane to the other end, the elastic wave intensity captured by the elastic wave sensor 12 gradually decreases, and an electrical signal with gradually decreasing intensity is generated. In this way, the controller can identify the sliding direction based on the change in the intensity of the electrical signal generated by the elastic wave sensor 12.

[0052] When multiple elastic wave sensors 12 are provided, the sliding direction can be determined by the time sequence of the electrical signals of the multiple elastic wave sensors 12. For example, in some embodiments, the elastic wave sensors 12 include a first elastic wave sensor 12 and a second elastic wave sensor 12 arranged at intervals along the circumferential direction of the ring body 11. First, the start signal and the end signal of the first electrical signal of the first elastic wave sensor 12 and the second electrical signal of the second elastic wave sensor 12 are acquired. Then, based on the time sequence, time difference, and / or intensity difference between the start signal of the first electrical signal and the start signal of the second electrical signal, and the time sequence, time difference, and / or intensity difference between the end signal of the first electrical signal and the end signal of the second electrical signal, the sliding direction of the ring body 11 is identified.

[0053] Specifically, in some embodiments, when the starting signal of the first electrical signal precedes the starting signal of the second electrical signal and the ending signal of the first electrical signal follows the ending signal of the second electrical signal, it is determined that the ring body is sliding along a first direction; otherwise, it is determined that the ring body is sliding along a second direction, where the second direction is opposite to the first direction. In other embodiments, it can also be determined that the ring body is sliding along a first direction when the time difference between the starting signal of the first electrical signal and the starting signal of the second electrical signal is positive, and the time difference between the ending signal of the second electrical signal and the ending signal of the first electrical signal is positive; otherwise, it is determined that the ring body is sliding along a second direction. In still other embodiments, it can also be determined that the intensity difference between the starting signal of the first electrical signal and the starting signal of the second electrical signal is positive, and the intensity difference between the ending signal of the second electrical signal and the ending signal of the first electrical signal is positive; otherwise, it is determined that the ring body is sliding along a second direction. Of course, in other embodiments, the sliding direction can also be identified by arbitrarily combining the time sequence, time difference, and intensity difference.

[0054] It should be noted that the ring body 11 has an inner end face and an outer end face. When worn in the forward position, the inner end face is close to the palm, while when worn in the reverse position, the inner end face is far away from the palm. When the ring body 11 itself is used as a reference, when viewed from the outer end face toward the inner end face, the ring body 11 has two sliding directions: clockwise and counterclockwise, corresponding to the first direction and the second direction. For example, the first direction can be set as the clockwise direction and the second direction as the counterclockwise direction.

[0055] Furthermore, when using the user's subjective perspective as a reference, the left and right hands are positioned on the left and right sides of the torso, respectively. Sliding inward refers to sliding along the direction closer to the center of the user's torso, while sliding outward refers to sliding away from the center of the torso. Specifically, when the smart ring 10 is worn on the left hand, sliding from the left side of the fingertip to the right is the same direction as sliding from the right side of the fingertip to the left when the smart ring 10 is worn on the right hand, and both are configured to slide inward. Similarly, when the smart ring 10 is worn on the left hand, sliding from the right side of the fingertip to the left is the same direction as sliding from the left side of the fingertip to the right when the smart ring 10 is worn on the right hand, and both are configured to slide outward. It can be understood that if a user habitually slides inward or outward when operating with one hand, they will follow this habit regardless of whether the smart ring 10 is worn on the left or right hand.

[0056] It is understandable that the operating habits that users find easier to understand and remember, including swiping inwards and outwards, may differ from the swiping direction sensed by the ring body 11 due to the wearing position (left or right hand) and wearing posture (front or back). For example, when the ring body 11 is worn frontally on the left hand, swiping inwards (from the user's perspective) will result in the ring body 11 sensing a counter-clockwise swiping motion (from the ring body 11's perspective); when the ring body 11 is worn frontally on the right hand, swiping inwards will result in the ring body 11 sensing a clockwise swiping motion; and when the ring body 11 is worn backwards on the left hand, swiping inwards will result in the ring body 11 sensing a clockwise swiping motion, and when the ring body 11 is worn backwards on the right hand, swiping inwards will result in the ring body 11 sensing a counter-clockwise swiping motion.

[0057] Therefore, considering user operating habits, in order to accurately identify the user's true swiping intentions, in some embodiments, the controller's operating mode includes a left-hand mode and a right-hand mode. Users can wear the smart ring 10 on either their left or right hand and select the corresponding left-hand or right-hand mode. For example, in right-hand mode, a clockwise swipe on the smart ring 10 is interpreted as an inward swipe, and in left-hand mode, a counter-clockwise swipe on the smart ring 10 is also interpreted as an inward swipe, controlling the smart glasses to execute the same command, such as decreasing the volume of the smart glasses. Similarly, in right-hand mode, a counter-clockwise swipe on the smart ring 10 is interpreted as an outward swipe, and in left-hand mode, a clockwise swipe on the smart ring 10 is also interpreted as an outward swipe, controlling the smart glasses to execute the same command, such as increasing the volume of the smart glasses. This makes it easier for users to remember the control logic and better suits the habit of single-handed operation. Of course, in other embodiments, there may be no distinction between left and right-hand modes, with only one default mode, for example, a default right-hand mode that the user can only wear on their right hand.

[0058] Specifically, the selection of left-hand or right-hand mode can be remotely set via smart glasses. For example, the smart glasses may have two corresponding option buttons, allowing the user to remotely control the smart ring 10 to enter either left-hand or right-hand mode. Alternatively, in other embodiments, switching between left-hand and right-hand modes can be achieved by recognizing touch operations on the smart ring 10. For instance, the smart ring 10 may default to right-hand mode upon startup; if a long press is detected on the smart ring 10, it switches to left-hand mode; if another long press is detected, it switches back to right-hand mode, and so on.

[0059] Considering that the sliding direction is also affected by the wearing state of the smart ring 10, in order to more accurately identify the user's true sliding operation intention, in some embodiments, a guide mark 17 for indicating the wearing direction is provided on the outer peripheral surface of the ring body 11. Specifically, the guide mark 17 is a linear mark provided on the outer peripheral surface of the ring body 11 near the axial direction of the ring body 11; or, the guide mark 17 is a guide arrow, guide triangle, or guide text provided on the outer peripheral surface of the ring body 11. In this way, the guide mark 17 can guide and standardize the user's wearing method, so that the smart ring 10 can be in a positive wearing posture whether it is on the left or right hand. This simplifies the control logic of the elastic wave detection control component and improves its response speed while accurately identifying touch operations. Of course, in other embodiments, the guide mark 17 can also be in other forms.

[0060] Furthermore, considering that users may not be able to wear the ring correctly according to the guide mark 17 in special circumstances, such as when they cannot see the guide mark 17 clearly in a dimly lit environment and are in a hurry to use it, the smart ring 10 may also include a wearing direction detection device in some embodiments. This device includes a first detection element and a second detection element disposed on the inner side of the ring body 11. The first and second detection elements are spaced apart along the axial direction of the ring body 11 and are both electrically connected to the controller. Thus, the wearing direction of the smart ring 10 is determined by the triggering sequence of the first and second detection elements. This wearing direction includes the first and second axial directions of the ring body 11, with the first and second axial directions being opposite. For example, the first axial direction is from the outer end face towards the inner end face, and the second axial direction is from the inner end face towards the outer end face. Therefore, when the wearing direction is the first axial direction, it is a forward wearing posture; when the wearing direction is the second axial direction, it is a reverse wearing posture. When the first detection element triggers before the second detection element, the wearing direction is determined to be the first axial direction; when the second detection element triggers before the first detection element, the wearing direction is determined to be the second axial direction.

[0061] Specifically, in some embodiments, both the first and second detection elements are configured as capacitive sensors or pressure sensors. This allows for timely triggering of the first and second detection elements during wear, improving trigger sensitivity, and the structure is simple and easy to implement. Of course, in other embodiments, the first and / or second detection elements can also be configured as laser sensors, infrared sensors, or ultrasonic sensors, etc.

[0062] The present invention proposes an interaction method based on a smart ring, applicable to smart rings. Please refer to [link / reference]. Figure 7 In the first embodiment of the interaction method based on a smart ring of the present invention, the interaction method based on a smart ring includes steps S10, S20 and S30, as follows:

[0063] Step S10: Acquire elastic wave signals and generate electrical signals by means of elastic wave sensors configured on the ring body of the smart ring.

[0064] Specifically, the smart ring includes a ring body and an elastic wave detection and control component disposed on the ring body. The elastic wave detection and control component includes an elastic wave sensor and a controller electrically connected to each other. The elastic wave sensor is disposed on the ring body. When the user touches the ring body, it will cause a tiny ripple. This ripple propagates on the ring body in the form of an elastic wave and is captured by the elastic wave sensor. Then, the elastic wave sensor converts the captured elastic wave signal into an electrical signal and transmits it to the controller.

[0065] It is understandable that the elastic waves generated by touch operation can still be captured by the elastic wave sensor after propagating a long distance on the smart ring. This means that the touch operation area that the elastic wave sensor can sense can basically cover the entire ring body.

[0066] Step S20: Identify the touch operation received by the ring body based on the electrical signal.

[0067] In this embodiment, the touch operation includes single click, double click, and / or swipe. The swipe can be between different positions on the same rigid structural member, such as sliding from one end of the ring body to the other end; or it can be sliding from one of multiple rigid structural members to another. For example, in an embodiment where the ring body is an open ring and the two ends of the power supply battery are connected to the two ends of the opening of the ring body to form a closed ring, the power supply battery can slide to the ring body or the ring body can slide to the power supply battery.

[0068] Specifically, optionally, the touch operation received by the ring body is identified based on the number of electrical signals within the first time interval. For example, it is determined whether the number of electrical signals acquired within the first time interval is 1 or 2; when the number of electrical signals is 1, the touch operation is determined to be a single click; when the number of electrical signals is 2, the touch operation is determined to be a double click, and so on. It is worth mentioning that, to avoid misjudgment, in this embodiment, optionally, the double click is determined to be valid only when the time interval between the two electrical signals is greater than the second time interval; the second time interval is less than the first time interval. Those skilled in the art can set the first time interval and the second time interval based on design experience, therefore, this application does not make specific limitations here.

[0069] Step S30: Send a control command to the smart glasses that are wirelessly connected to the smart ring according to the touch operation.

[0070] In this embodiment, smart glasses include, but are not limited to, VR (Virtual Reality) glasses, AR (Augmented Reality) glasses, MR (Mediated Reality) glasses, or Bluetooth audio glasses. Taking AR glasses as an example, control commands are sent to the smart glasses based on touch operations. These commands include, but are not limited to, controlling the working state of different functional components of the smart glasses and controlling different functional applications of the smart glasses. Functional applications include controlling applications, such as switching between different interfaces or different applications within the same application. Functional components include, but are not limited to, speakers, cameras, and optical engines. For example, clicking on a smart ring to turn the speaker off, double-clicking to turn the speaker on, and sliding to adjust the speaker volume. It is understood that the technical solution of this invention does not specifically limit the correspondence between touch operations and control commands; those skilled in the art can arbitrarily combine and adjust them according to actual design requirements.

[0071] The technical solution of this invention replaces traditional mechanical buttons or capacitive touch buttons with an elastic wave detection and control component, increasing the coverage area of ​​the sensing area on the smart ring. Touch operations performed by the user in any area of ​​the ring body can be detected and recognized, enabling one-handed operation even when the elastic wave sensor is not located on the fingertip. This improves the convenience of human-computer interaction and enhances the ease of remotely controlling smart glasses via the smart ring. Secondly, changes in the elastic wave signal accurately identify various types of touch operations, such as single clicks, double clicks, or swipes, enriching the design and freedom of touch operation, thus improving the flexibility of the smart ring. Furthermore, since the elastic wave sensor can be applied to rigid structural components made of conductive or non-conductive materials, it avoids material limitations on the smart ring, making the technical solution applicable to a wide range of scenarios.

[0072] In the second embodiment of the interaction method based on a smart ring of the present invention, based on the first embodiment of the interaction method based on a smart ring described above, the elastic wave sensor includes a first elastic wave sensor and a second elastic wave sensor spaced apart along the circumferential direction of the ring body. The step of identifying the touch operation received by the ring body based on the electrical signal includes steps S21 and S22, as follows:

[0073] Step S21: Obtain the start signal and end signal of the first electrical signal of the first elastic wave sensor and the second electrical signal of the second elastic wave sensor, respectively.

[0074] Specifically, when a user taps or slides on the ring body, the generated elastic wave signal will remain on the ring body for a certain period of time and have a start signal and an end signal on the time axis. When the elastic wave sensor receives the start elastic wave signal, it will generate a corresponding start electrical signal, and when it receives the end elastic wave signal, it will generate a corresponding end electrical signal.

[0075] Step S22: Based on the time sequence, time difference, and / or intensity difference between the start signal of the first electrical signal and the start signal of the second electrical signal, and the time sequence, time difference, and / or intensity difference between the last signal of the first electrical signal and the last signal of the second electrical signal, identify the direction of sliding of the ring body.

[0076] Specifically, in some embodiments, when the time sequence of the start signal of the first electrical signal is before the start signal of the second electrical signal, and the time sequence of the last signal of the first electrical signal is after the last signal of the second electrical signal, it is determined that the ring body is sliding along the first direction; otherwise, it is determined that the ring body is sliding along the second direction; the second direction is opposite to the first direction.

[0077] In other embodiments, the ring body is determined to be sliding along the first direction if the time difference between the start signal of the first electrical signal and the start signal of the second electrical signal is positive, and the time difference between the last signal of the second electrical signal and the last signal of the first electrical signal is positive; otherwise, the ring body is determined to be sliding along the second direction.

[0078] In some other embodiments, the ring body may be determined to be sliding along the first direction if the intensity difference between the starting signal of the first electrical signal and the starting signal of the second electrical signal is positive, and the intensity difference between the last signal of the second electrical signal and the last signal of the first electrical signal is positive; otherwise, the ring body may be determined to be sliding along the second direction.

[0079] Of course, in other embodiments, the sliding direction can also be identified by arbitrarily combining the time sequence, time difference, and intensity difference.

[0080] Optionally, the signal is determined to be valid only when its intensity value is greater than or equal to a first preset intensity value, and comparisons are made only between valid signals based on intensity difference, time sequence, and time difference. This reduces the risk of false triggering, such as vibrations detected by the elastic wave sensor when a fist is accidentally clenched and lightly touched. It is understood that those skilled in the art can specifically set the first preset intensity value according to the product structure of different smart rings and the deployment method of the elastic wave sensor.

[0081] In the third embodiment of the interaction method based on a smart ring of the present invention, based on the second embodiment of the interaction method based on a smart ring described above, the interaction method based on a smart ring further includes step S40, as follows:

[0082] Step S40: Detect the wearing direction of the smart ring using a wearing direction detection device configured on the ring body.

[0083] Specifically, the wearing direction includes a first axis and a second axis of the ring body, with the first axis being opposite to the second axis. For example, the first axis can be the direction from the outer end face of the ring body towards its inner end face, and the second axis can be the direction from the inner end face of the ring body towards its outer end face. When the wearing direction is the first axis, it is a forward wearing posture, in which case the inner end face of the ring body is close to the palm; when the wearing direction is the second axis, it is a reverse wearing posture, in which case the inner end face of the ring body is away from the palm. Of course, in other embodiments, the first axis can also be the direction from the inner end face of the ring body towards its outer end face, and the second axis can be the direction from the outer end face of the ring body towards its inner end face.

[0084] When viewed along the first axis, the ring itself has two sliding directions: clockwise and counterclockwise. These correspond to the first and second directions, respectively. For example, the first direction can be set as clockwise, and the second direction as counterclockwise. If the smart ring's interaction program is defaulted to wearing the smart ring along the first axis, and is set to generate a first control command upon sensing clockwise sliding and a second control command upon sensing counterclockwise sliding, then when the user wears the smart ring along the second axis, the sliding operation intended to generate the first control command will actually cause the smart ring to sense counterclockwise sliding and generate the second control command. This results in the smart glasses failing to correctly respond to the user's true intention. Therefore, this embodiment improves the accuracy of recognizing the user's true intention by identifying the wearing direction and using it as one of the criteria for judging the user's operation, thereby improving the ease of use and accuracy of the smart ring.

[0085] Of course, in other embodiments, the wearing direction detection device may not be provided. For example, it can guide and standardize the user's wearing method, requiring the user to wear the smart ring in accordance with the first axis (i.e., the forward wearing posture); or prompt the user to make necessary adjustments to the touch operation according to the different wearing postures.

[0086] In the fourth embodiment of the interaction method based on a smart ring of the present invention, based on the third embodiment of the interaction method based on a smart ring described above, the wearing direction detection device includes a first detection element and a second detection element disposed on the inner side of the ring body, the first detection element and the second detection element being spaced apart along the axial direction of the ring body; the step of detecting the wearing direction of the smart ring by means of the wearing direction detection device disposed on the ring body includes steps S41, S42 and S43, as follows:

[0087] Step S41: Acquire the first trigger signal of the first detection element and the second trigger signal of the second detection element;

[0088] Step S42: When the timing sequence of the first trigger signal is earlier than the timing sequence of the second trigger signal, the wearing direction is determined to be the first axis;

[0089] Step S43: When the timing sequence of the first trigger signal is after the timing sequence of the second trigger signal, the wearing direction is determined to be the second axis, which is opposite to the first axis.

[0090] In this embodiment, the ring body has opposing inner and outer surfaces. When the smart ring is worn on a finger, the inner surface is close to the finger and the outer surface is away from the finger. The first detection element is adjacent to the inner end face of the ring body, and the second detection element is adjacent to the outer end face of the ring body. When the user wears the smart ring along the first axis, the inner end face of the ring body first slips onto the finger, causing the first detection element to first come into contact with the finger and generate a first trigger signal. Then, when the outer end face of the ring body also slips onto the finger, the second detection element comes into contact with the finger and generates a second trigger signal. Thus, by determining the timing of the triggering of the first and second detection elements, the wearing direction can be accurately identified, and the structure is simple and easy to implement. Of course, in other embodiments, a distance sensor may be provided on both the inner and outer end faces of the ring body. When the user wears the smart ring along the first axis, the distance sensor on the inner end face can detect the distance from the inner end face to the base of the finger (i.e., the edge of the palm). This distance gradually decreases as the smart ring is gradually put on the finger. Meanwhile, the distance sensor on the outer end face has no effective signal or the measured distance value does not change significantly. In this case, the wearing direction can be determined to be the first axis. Otherwise, the wearing direction can be determined to be the second axis.

[0091] Optionally, both the first and second detection elements can be configured as capacitive sensors or pressure sensors. This allows for timely triggering of the first and second detection elements during wear, improving trigger sensitivity and simplifying the structure for easy implementation. Alternatively, in other embodiments, the first and / or second detection elements can also be configured as laser sensors, infrared sensors, or ultrasonic sensors, etc.

[0092] It's important to note that when using the user's subjective perspective as a reference, the left and right hands are positioned on the left and right sides of the torso, respectively. Sliding inwards refers to sliding along the direction closer to the center of the user's torso, while sliding outwards refers to sliding away from the center of the torso. Specifically, when the smart ring is worn on the left hand, sliding from the left side of the fingertip to the right is the same direction as sliding from the right side of the fingertip to the left when the smart ring is worn on the right hand, and both are configured to slide inwards. Similarly, when the smart ring is worn on the left hand, sliding from the right side of the fingertip to the left is the same direction as sliding from the left side of the fingertip to the right when the smart ring is worn on the right hand, and both are configured to slide outwards. This means that if a user habitually slides inwards or outwards when operating with one hand, they will follow this habit regardless of whether the smart ring is worn on their left or right hand.

[0093] It's understandable that user-friendly operating habits, such as swiping inwards and outwards, may differ from the swiping direction sensed by the ring itself, depending on the wearing position (left or right hand) and posture (front or back). For example, when the ring is worn frontally on the left hand, swiping inwards (from the user's perspective) is perceived as a counter-clockwise swiping motion (from the ring itself's perspective); when worn frontally on the right hand, swiping inwards is perceived as a clockwise swiping motion; and when worn backwards on the left hand, swiping inwards is perceived as a clockwise swiping motion, and when worn backwards on the right hand, swiping inwards is perceived as a counter-clockwise swiping motion.

[0094] Therefore, considering user operating habits, in order to more accurately identify the user's true swiping intentions, in some embodiments, the controller's operating mode includes a left-hand mode and a right-hand mode. Users can wear the smart ring on either their left or right hand and select the corresponding left-hand or right-hand mode. For example, in right-hand mode, a clockwise swipe on the smart ring is interpreted as an inward swipe, and in left-hand mode, a counter-clockwise swipe is also interpreted as an inward swipe, controlling the smart glasses to execute the same command, such as decreasing the volume. Similarly, in right-hand mode, a counter-clockwise swipe is interpreted as an outward swipe, and in left-hand mode, a clockwise swipe is also interpreted as an outward swipe, controlling the smart glasses to execute the same command, such as increasing the volume. This makes it easier for users to remember the control logic and better suits the habit of single-handed operation. Of course, in other embodiments, there may be no distinction between left and right-hand modes, with only one default mode, for example, a default right-hand mode that the user can only wear on their right hand.

[0095] Specifically, the selection of left-hand or right-hand mode can be remotely set via smart glasses. For example, the smart glasses may have two corresponding option buttons, allowing the user to remotely control the smart ring to switch between left-hand and right-hand modes. Alternatively, in other embodiments, switching between left-hand and right-hand modes can be achieved by recognizing touch operations on the smart ring. For instance, the smart ring might default to right-hand mode upon startup; if a long press is detected, it switches to left-hand mode; if another long press is detected, it switches back to right-hand mode, and so on.

[0096] Taking the example of a smart ring remotely controlling the volume of smart glasses after a sliding operation as an example, the correspondence between the user's sliding operation, the actual sliding direction of the ring, and the operation performed by the smart glasses under different wearing positions and directions can be seen in the table below. It can be seen that by combining the wearing direction with the actual sliding direction, a clear logical relationship can be established between the user's operation and the smart glasses' execution: sliding inward corresponds to decreasing the volume, and sliding outward corresponds to increasing the volume. This makes it easier for users to understand and remember the control logic, thereby improving the ease of use of the smart ring. In other words, by accurately identifying the wearing direction, the user's true operational intent can be more accurately identified, thus enabling the ring to respond to the user's true operational intent regardless of how it is worn.
