[0022] Compared with the prior art, the technical solution of the embodiments of the present invention has the following advantages:

[0023] The smart ring provided in this invention is used to recognize hand gestures. The smart ring includes a ring-shaped body, a sensor module disposed on the surface of the ring-shaped body, and an inertial measurement unit (IMU) integrated inside the ring-shaped body. Compared to existing smart rings that only use the IMU to recognize hand gestures, this invention, by placing the sensor module on the surface of the ring-shaped body, can recognize hand gestures based on data from both the sensor module and the IMU when the user wears the smart ring. This reduces the computational load in the IMU, thereby lowering its power consumption. Furthermore, the reduced computational load also lowers the system latency and improves the response rate of the smart ring, thus enhancing its robustness. Attached Figure Description

[0027] As the background technology shows, current smart rings recognize hand gestures through simulation using acceleration and gyroscopes. With the diversification of gesture functions, the computing power requirements of the main control chip are increasing, leading to higher power consumption of the main control chip in smart rings. At the same time, the computational load of the algorithm on the main control chip of smart rings has increased significantly, which increases the system latency of smart rings, reduces the response rate of smart rings, and thus affects the robustness of smart rings.

[0028] To address the technical issues, this invention provides a smart ring for recognizing hand gestures, comprising: a ring-shaped body; a sensor module disposed on the surface of the ring-shaped body; and an inertial measurement unit integrated inside the ring-shaped body.

[0029] The smart ring provided in this invention is used to recognize hand gestures. The smart ring includes a ring-shaped body, a sensor module disposed on the surface of the ring-shaped body, and an inertial measurement unit (IMU) integrated inside the ring-shaped body. Compared to existing smart rings that only use the IMU to recognize hand gestures, this invention, by placing the sensor module on the surface of the ring-shaped body, can recognize hand gestures based on data from both the sensor module and the IMU when the user wears the smart ring. This reduces the computational load in the IMU, thereby lowering the power consumption of the smart ring. Simultaneously, the reduced computational load in the IMU lowers the system latency of the smart ring, improving its response rate and thus enhancing its robustness.

[0030] To make the above-mentioned objects, features and advantages of the embodiments of the present invention more apparent and understandable, the following description is provided in conjunction with the appendix to the specification. Figures 1 to 2 Specific embodiments of the present invention will be described in detail below. Figure 1 This is a schematic diagram of the structure of one embodiment of the smart ring of the present invention; Figure 2 This is a joint diagram of a specific finger corresponding to an embodiment of the smart ring of the present invention.

[0031] The smart ring 100 includes: a ring-shaped body 160; a sensor module 110 disposed on the surface of the ring-shaped body 160; and an inertial measurement unit 180 integrated inside the ring-shaped body 160.

[0032] It should be noted that, compared to the smart ring 100 which only includes a ring-shaped body 160 and an inertial measurement unit 180 integrated inside the ring-shaped body 160, this embodiment, by setting a sensor module 110 on the surface of the ring-shaped body 160, can identify hand posture based on the data information fed back by the sensor module 110 and the inertial measurement unit 180 when the user wears the smart ring 100. This reduces the amount of data computation in the inertial measurement unit 180, thereby reducing the power consumption of the smart ring 100. At the same time, because the amount of data computation in the inertial measurement unit 180 is reduced, the system latency of the smart ring 100 is reduced, improving the response rate of the smart ring 100, thereby improving the robustness of the smart ring 100.

[0033] Specifically, the annular body 160 provides a support platform for setting up the smart ring 100.

[0034] As an example, the annular body 160 includes an outer shell 101 and an inner shell 102 disposed on the inner circumferential surface of the outer shell 101.

[0035] Specifically, the outer shell 101 and the inner shell 102 provide a bearing surface for mounting the sensor module 110.

[0036] It should be noted that the space between the outer shell 101 and the inner shell 102 is used to house the inertial measurement unit 180, so that the outer shell 101 and the inner shell 102 protect the inertial measurement unit 180. At the same time, it also makes the surface of the annular body 160 relatively smooth, which can improve the comfort of the user's hand when the annular body 160 is worn on the user's designated finger.

[0037] As an example, the annular body 160 has a through hole 130 that provides space for the user to wear the smart ring 100.

[0038] In this embodiment, the material of the annular body 160 includes one or more of ceramic materials, plastic materials, resin materials, and alloy materials.

[0039] In this embodiment, the diameter of the annular body 160 is used as the dividing line AA. The annular body 160 includes a first body 105 and a second body 103 that contacts the first body 105. The first body 105 and the second body 103 are symmetrical about the dividing line AA.

[0040] Specifically, by setting the first body 105 and the second body 103, it is beneficial to accurately set the touch area on the first body 105 or the second body 103, so that the data information collected by the sensor module 110 set on the touch area is more accurate, thereby improving the accuracy of the smart ring 100 in recognizing hand posture.

[0041] In this embodiment, the surface of the annular body 160 includes multiple touch areas, and the multiple touch areas are located on the surface of the first body 105.

[0042] It should be noted that the touch area is the area where the sensor module 110 is located.

[0043] It should also be noted that during the process of the user wearing the smart ring 100 on a designated finger, if the first body 105 is worn below the designated finger, the second body 103 is located above the designated finger. Accordingly, when the user's hand makes gestures such as clenching a fist, loosening, closing the fingers, picking, or pinching, the designated finger will be squeezed by other fingers, thereby causing the touch area on the surface of the first body 105 to feed back data information, and then the smart ring 100 can recognize the hand gesture based on the feedback data information.

[0044] In other embodiments, the surface of the annular body 160 includes a plurality of touch areas (not labeled) located on the surface of the second body 103.

[0045] It should be noted that the touch area is the area where the sensor module 110 is located.

[0046] It should also be noted that during the process of the user wearing the smart ring 100 on a designated finger, if the second body 103 is worn below the designated finger, the first body 105 is located above the designated finger. Accordingly, when the user's hand makes gestures such as clenching a fist, loosening, closing the fingers, picking, or pinching, the designated finger will be squeezed by other fingers, thereby causing the touch area on the surface of the second body 103 to feed back data information, which in turn allows the smart ring 100 to recognize the hand gesture based on the feedback data information.

[0047] In this embodiment, the touch area is located at the intersection of the dividing line AA and the first body 105, and at the intersection of the extension line BB perpendicular to the dividing line AA and the first body 105.

[0048] It should be noted that the touch area is located at the intersection of the dividing line AA and the first body 105, and at the intersection of the extension line BB perpendicular to the dividing line AA and the first body 105. When the user wears the smart ring 100 on a designated finger, the intersection of the dividing line AA and the first body 105 is the position where the pressure between the designated finger and its adjacent finger is the greatest. The intersection of the extension line BB perpendicular to the dividing line AA and the first body 105 is the position where the pressure between the first joint 190 and the third joint 191 of the designated finger is the greatest when the user is in a fist-clenching posture. This allows the touch area of ​​the smart ring 100 to acquire data information in a timely manner and determine the user's hand posture.

[0049] In other embodiments, the touch area is located at the intersection of the dividing line and the second body, and at the intersection of an extension line perpendicular to the dividing line and the extension line with the second body.

[0050] It should be noted that the touch area is located at the intersection of the dividing line and the second body, and at the intersection of the extension line perpendicular to the dividing line and the second body. When the user wears the smart ring on a designated finger, the intersection of the dividing line and the second body is the location where the pressure between the designated finger and its adjacent finger is the greatest. The intersection of the extension line perpendicular to the dividing line and the second body is the location where the pressure between the first and third joints of the designated finger is the greatest when the user is making a fist. This allows the touch area of ​​the smart ring to acquire data information in a timely manner and determine the user's hand posture.

[0051] In this embodiment, the annular body 160 includes an inner surface (not labeled) and an outer surface (not labeled) opposite to the inner surface.

[0052] Specifically, both the inner and outer surfaces provide bearing surfaces for the sensor module 110.

[0053] It should be noted that when a user makes a fist, release, close, grasp, or pinch gesture on a designated finger wearing the smart ring 100, pressure will occur between the designated finger and its adjacent fingers. The sensor module 110 will feed back data information due to this pressure, enabling the smart ring 100 to recognize the hand gesture based on the data information fed back by the sensor module 110. This reduces the amount of data computation in the inertial measurement unit 180, thereby reducing the power consumption of the smart ring 100. At the same time, the reduced amount of data computation in the inertial measurement unit 180 reduces the system latency of the smart ring 100, improves the response rate of the smart ring 100, and thus improves the robustness of the smart ring 100.

[0054] It should also be noted that the sensor module 110 will provide feedback data due to compression, enabling the smart ring 100 to recognize hand postures based on the data feedback from the sensor module 110. This reduces the amount of data computation in the inertial measurement unit 180. In the process of recognizing hand postures, the smart ring collects data feedback from both the sensor module 110 and the inertial measurement unit 180. Since the sensor module 110 shares some of the data computation, the amount of data computation in the inertial measurement unit 180 is reduced.

[0055] In this embodiment, the sensor module 110 is disposed in the touch area.

[0056] As an example, the sensor module 110 is disposed on the inner surface of the annular body 160.

[0057] Specifically, the sensor module 110 is disposed on the inner surface of the annular body 160, which makes the smart ring 100 more aesthetically pleasing. At the same time, it reduces the probability of the sensor module 110 being damaged during a fall, thereby improving the reliability of the smart ring 100.

[0058] In other embodiments, the sensor module 110 may also be disposed on the outer surface of the annular body 160.

[0059] In other embodiments, the sensor module 110 is disposed on the inner and outer surfaces of the annular body 160.

[0060] Specifically, when the sensor module 110 is disposed on the inner surface and the outer surface of the annular body 160, the sensor module 110 disposed on the inner surface and the sensor module 110 disposed on the outer surface are symmetrical about the annular body 160.

[0061] It should be noted that the sensor module 110 disposed on the inner surface and the sensor module 110 disposed on the outer surface are symmetrical to the annular body 160, so that the smart ring 100 can sense the squeezing force on both the inner and outer surfaces, thereby making the smart ring 100 more sensitive.

[0062] As an example, the sensor module 110 includes one or more of the following: capacitive touch sensor, inductive touch sensor, resistive touch sensor, physical button, pressure sensor, and proximity sensor.

[0063] Specifically, capacitive touch sensors, inductive touch sensors, resistive touch sensors, physical buttons, pressure sensors, and proximity sensors all generate electrical signals when a user's designated finger is squeezed, enabling the smart ring 100 to recognize hand gestures based on the feedback electrical signals.

[0064] It should be noted that when the smart ring 100 is worn on a designated finger and the finger makes an unfolding or rotating gesture, the inertial measurement unit 180 can identify the user's hand gesture based on information such as the acceleration, angular velocity and displacement direction of the designated finger.

[0065] In this embodiment, the inertial measurement unit 180 includes an accelerometer and a gyroscope.

[0066] As an example, the inertial measurement unit 180 is adapted to acquire rotational and displacement information in the 6-DOF pose of the hand.

[0067] It should be noted that by acquiring the rotation and displacement information in the 6-DOF pose of the hand, the main control chip in the smart ring 100 can recognize the user's hand posture based on a deep learning model.

[0068] In this embodiment, the smart ring 100 further includes a data acquisition module 161, which is integrated inside the ring-shaped body 160. The data acquisition module 161 is adapted to acquire data information obtained by the sensor module 110 and the inertial measurement unit 180.

[0069] Specifically, the data acquisition module 161 in the smart ring 100 is responsible for collecting and processing data from the sensor module 110 and the inertial measurement unit 180 (IMU), ensuring that the data collected from the sensor module 110 and the inertial measurement unit 180 can be accurately and effectively acquired and transmitted for subsequent gesture recognition analysis and application.

[0070] As an example, the data acquisition module 161 adopts a low-power design, which can further reduce the power consumption of the smart ring 100 and extend the running time of the smart ring 100.

[0071] In this embodiment, the smart ring 100 further includes a main control chip 162, which is integrated inside the ring-shaped body 160. The main control chip 162 is adapted to acquire the data information collected by the data acquisition module 161 and recognize hand posture based on the data information.

[0072] Specifically, the main control chip 162 is used to process the data information collected by the data acquisition module 161, and at the same time, it can also control various functions of the smart ring 100 (such as communication between the smart ring 100 and other electronic devices).

[0073] In this embodiment, the main control chip 162 recognizes hand gestures based on a deep learning model.

[0074] For example, when the sensor modules 110 of the touch area all return signals, the main control chip 162 can identify that the user's hand is in a clenched fist posture based on a deep learning model.

[0075] For example, when the sensor module 110 located at the intersection of the dividing line AA and the first body 105, and the sensor module 110 located at the intersection of the extension line BB perpendicular to the dividing line AA and the first body 105, the main control chip 162 can identify that the user's hand is in a five-finger-closed posture based on a deep learning model.

[0076] In this embodiment, the smart ring 100 further includes a power module 170, which is integrated inside the ring-shaped body 160. The power module 170 is adapted to provide power voltage to the sensor module 110 and the inertial measurement unit 180.

[0077] Specifically, the power module 170 is adapted to provide power voltage to the sensor module 110 and the inertial measurement unit 180, enabling the smart ring 100 to provide users with a shrinkage recognition function.

[0078] Accordingly, embodiments of the present invention provide a method for recognizing hand gestures. Wherein, Figure 3 This is a flowchart of the steps corresponding to one embodiment of the present invention for recognizing hand postures.

[0079] Reference Figures 1 to 2 Step S1: Provide the smart ring 100 provided by the present invention, which is worn on the user's designated finger.

[0080] Specifically, the detailed description of the smart ring 100 will not be repeated here; please refer to the description in the foregoing embodiments.

[0081] Reference Figures 1 to 2 Step S2: Based on the data information obtained by the sensor module 110 and the inertial measurement unit 180, identify the hand posture.

[0082] Specifically, by setting a sensor module 110 on the surface of the annular body 160, when the user wears the smart ring 100, the hand posture can be identified based on the data information fed back by the sensor module 110 and the inertial measurement unit 180. This reduces the amount of data computation in the inertial measurement unit 180, thereby reducing the power consumption of the smart ring 100. At the same time, because the amount of data computation in the inertial measurement unit 180 is reduced, the system latency of the smart ring 100 is reduced, the response rate of the smart ring 100 is improved, and thus the robustness of the smart ring 100 is enhanced.

[0083] As an example, the steps of identifying hand posture based on the data information obtained by the sensor module 110 and the inertial measurement unit 180 include: identifying hand posture based on the electrical signal obtained by the sensor module 110; and identifying hand posture based on the rotational and displacement information in the 6-DOF pose obtained by the inertial measurement unit 180.

[0084] It should be noted that when a user makes a fist, release, put their fingers together, pick up, or pinch gestures while wearing the smart ring 100 on their designated finger, pressure will occur between the designated finger and its adjacent fingers. The sensor module 110 will provide feedback data information due to the pressure, so that the smart ring 100 can recognize the hand gesture based on the feedback data information. This reduces the amount of data calculation in the inertial measurement unit 180, thereby reducing the power consumption of the smart ring 100.

[0085] It should also be noted that the sensor module 110 will provide feedback data due to compression, enabling the smart ring 100 to recognize hand postures based on the data feedback from the sensor module 110. This reduces the amount of data computation in the inertial measurement unit 180. In the process of recognizing hand postures, the smart ring collects data feedback from both the sensor module 110 and the inertial measurement unit 180. Since the sensor module 110 shares some of the data computation, the amount of data computation in the inertial measurement unit 180 is reduced.

[0086] Specifically, when the smart ring 100 is worn on a designated finger and makes gestures such as unfolding or rotating, no squeezing force is generated between the designated finger and its adjacent fingers, and the sensor module 110 does not feed back electrical signals. The rotation and displacement information in the 6-DOF pose obtained by the inertial measurement unit 180 can identify the user's hand posture based on information such as the acceleration, angular velocity and displacement direction of the designated finger.

[0087] Accordingly, embodiments of the present invention also provide an interactive system.

[0088] The interactive system includes: a smart ring, wherein the smart ring is the smart ring provided by the present invention; and an electronic device, wherein the electronic device is communicatively connected to the smart ring.

[0089] Specifically, by setting sensor modules on the surface of the ring-shaped body, when a user wears the smart ring, the hand posture can be identified based on the data information fed back by the sensor modules and the data information fed back by the inertial measurement unit. This reduces the amount of data computation in the inertial measurement unit, thereby reducing the power consumption of the smart ring. At the same time, because the amount of data computation in the inertial measurement unit is reduced, the system latency of the smart ring is reduced, improving the response rate of the smart ring and thus improving the robustness of the smart ring.

[0090] As an example, electronic devices include one or more of VR display devices, AR display devices, and MR display devices.

[0091] Specifically, VR display devices include VR glasses or VR helmets; AR display devices include AR glasses or AR helmets; and MR display devices include MR helmets or MR glasses.
