[0002] With the increasing prevalence of smart devices, their intelligent functions have become a key focus for users, such as wear status detection. Currently, common methods for detecting wear status rely on Hall effect sensors and accelerometers. However, accelerometers are prone to false detections in static states and consume significant time from the start of detection to obtaining a result, resulting in high latency. Furthermore, Hall effect sensors are unstable in weak magnetic field environments, leading to low sensitivity, and their manufacturing and integration costs are high. Therefore, the accuracy and sensitivity of these methods for detecting wear status are relatively low.

[0056] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or a wear status detection device capable of performing the above functions. The following description uses a wear status detection device as an example to illustrate this embodiment and the subsequent embodiments.

[0057] Based on this, embodiments of this application provide a method for detecting wearing status, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the wearing status detection method of this application.

[0058] In this embodiment, the wearing status detection method includes steps S10 to S40:

[0059] Step S10: Obtain the current temperature of the magnet assembly set on the target smart device, and determine the current magnetic field strength of the magnet assembly based on the current temperature.

[0060] It should be noted that the reference Figure 2 , Figure 2 This is a schematic diagram of the overall structure, specifically: the target smart device is an AR (Augmented Reality) glasses, and the magnetoresistive sensing device is an AMR switch (Anisotropic Magnetoresistive sensor). Taking the Resistive Switch as an example, 1 represents AR glasses, 2 represents AMR switches, 3 represents the front frame, 4 represents the temperature adjustment component, 5 represents the magnet component, 6 represents the hinge, and 7 represents the temple. The magnet component is set on the front frame structure of the AR glasses. Its setting method includes, but is not limited to, adhesive, magnetic attraction, snap-fit, screw fastening, etc. The shape of the magnet component can be a ring formed by multiple small magnet units arranged off-axis. The magnetic poles of the magnet component are divided into north pole (N pole) and south pole (S pole). The temperature adjustment component is set adjacent to the magnet component and is used to adjust the temperature of the magnet component. The front frame and temple of the AR glasses can be connected by hinges. The temple can rotate within a certain range around the hinge rotation axis. Multiple AMR switches are set on different temples. For example, one AMR switch is set on the left temple and one AMR switch is set on the right temple. Its setting method includes, but is not limited to, adhesive, magnetic attraction, snap-fit, screw fastening, etc. The arrangement of the AMR switches and magnet components is not fixed; it is only necessary to ensure that they can rotate relative to each other. For example, the magnet components can be set on the temples of the AR glasses, and multiple AMR switches can be set on the front frame of the AR glasses.

[0061] As we can understand it, an AMR switch refers to a sensor that uses the anisotropic magnetoresistance effect to detect changes in magnetic fields. It achieves its switching function by detecting the change in resistance caused by the magnetic field. The principle is as follows: the resistance of a ferromagnetic magnet component changes with the direction of the applied magnetic field. The resistance is minimum when the magnetic field is parallel to the current direction and maximum when it is perpendicular to the current direction. When the external magnetic field forms a zero-degree angle with the magnet's built-in magnetic field, the resistance does not change with the applied magnetic field. However, when the external magnetic field and the magnet's built-in magnetic field have a certain angle, the magnetization vector inside the magnet shifts, and the thin-film resistance decreases. This characteristic is called the anisotropic magnetoresistance effect. In other words, an AMR switch changes its resistance by detecting changes in the direction of the magnetic field, thereby triggering the switching action. AMR switches consume energy only when a change in magnetic field is detected, eliminating the need for continuous power supply and significantly reducing power consumption. This makes them ideal for battery-powered smart devices. Compared to Hall effect sensors, AMR switches operate stably in weaker magnetic fields. Compared to the latency of accelerometers and optical sensors, they offer faster response times, enabling real-time detection of the temple's opening and closing status. Furthermore, AMR switches require no complex mechanical structures or optical components, resulting in high integration, simple design, and low cost. They are less affected by external factors such as humidity, dust, and light, offering higher reliability and stability compared to capacitive and optical sensors. Utilizing a non-contact detection method, they eliminate mechanical wear defects and have a longer lifespan compared to mechanical switches.

[0062] It should be understood that temperature affects the magnetic field strength of the magnet assembly; for example, high temperatures can cause magnetic moment disorder and weaken magnetism. To effectively improve the current angle between the magnetoresistive sensing device and the magnet assembly, the current magnetic field strength of the magnet assembly needs to be determined based on the current temperature. This magnet unit can be a small neodymium iron boron magnet.

[0063] In addition, to avoid situations where the current magnetic field strength does not meet the preset strength conditions, this embodiment can also directly set the magnetic field strength of the magnet assembly to meet the preset strength conditions, and add a magnetic shielding layer and a temperature shielding layer around the target smart device to eliminate external interference and reduce the influence of the environmental magnetic field.

[0064] Step S20: When the current magnetic field strength does not meet the preset strength condition, the current temperature is adjusted by the temperature adjustment component corresponding to the magnet assembly.

[0065] It is understandable that when the current magnetic field strength does not meet the preset strength condition, it indicates that the magnetic field strength of the magnet assembly is weak. At this time, the current temperature can be adjusted by the temperature adjustment component corresponding to the magnet assembly to enhance the magnetic field strength, for example, by lowering the temperature of the magnet assembly.

[0066] Further, step S20 includes: when the current magnetic field strength does not meet the preset strength condition, determining the magnetic field strength difference based on the current magnetic field strength and the preset strength condition; acquiring the characteristic information and material information of the magnet assembly, and determining the temperature difference corresponding to the magnetic field strength difference based on the characteristic information and the material information; determining the target operating parameters of the temperature adjustment component corresponding to the magnet assembly based on the temperature difference; and controlling the temperature adjustment component to adjust the current temperature in a manner that operates according to the target operating parameters.

[0067] It should be understood that, in order to effectively improve the accuracy of adjusting the current temperature, when it is determined that the current magnetic field strength does not meet the preset strength condition, the difference in magnetic field strength is determined based on the current magnetic field strength and the preset strength condition. Since the way to determine the temperature difference is different for magnet components with different characteristic information and different material information, it is necessary to determine the temperature difference corresponding to the difference in magnetic field strength based on the characteristic information and material information. The target operating parameter refers to the operating parameter that can adjust the current temperature of the magnet component so that the adjusted current temperature meets the preset strength condition.

[0068] Step S30: Detect the current angle between the multiple magnetoresistive sensors installed on the target smart device and the magnet assembly, and determine the magnetic field direction change data based on the current angle; wherein, there is a relative rotational relationship between the multiple magnetoresistive sensors and the magnet assembly.

[0069] It should be understood that the current angle refers to the angle between the multiple magnetoresistive sensors and the magnet assembly set on the target smart device at the current moment. Since the magnetoresistive sensors rotate with the temple, the angle between the magnetoresistive sensors and the magnet assembly is different when the temple is in different states, and the relative angle between the multiple magnetoresistive sensors and the magnet assembly changes, resulting in a change in the direction of the magnetic field. At this time, the change data of the magnetic field direction can be determined based on the current angle.

[0070] Further, the step of detecting the current angle between the multiple magnetoresistive sensors installed on the target smart device and the magnet assembly, and determining the magnetic field direction change data based on the current angle, includes: controlling the multiple magnetoresistive sensors installed on the target smart device to start respectively; detecting the current angle between the multiple started magnetoresistive sensors and the magnet assembly at the current moment and the historical angle at the previous moment respectively; determining the relative angle change value based on the current angle and the historical angle; and determining the magnetic field direction change data based on the relative angle change value.

[0071] It should be noted that when the temple of the target smart device starts to rotate, multiple magnetoresistive sensors installed on the target smart device are activated. At this time, the angle between the multiple magnetoresistive sensors and the magnet assembly is continuously detected, such as the current angle at the current moment and the historical angle at the previous moment. The relative angle change value refers to the change in angle from the previous moment to the current moment. After determining the relative angle change value based on the current angle and the historical angle, the magnetic field direction change data is determined based on the relative angle change value.

[0072] Further, after step S30, the method further includes: when any data in the various magnetic field direction change data does not meet the preset change condition, performing fault detection on the multiple magnetoresistive sensing devices respectively; determining the faulty magnetoresistive sensing device and the normal magnetoresistive sensing device based on the fault detection result; when the distance between the faulty magnetoresistive sensing device and the magnet assembly is greater than or equal to the distance between the normal magnetoresistive sensing device and the magnet assembly, selecting the magnetic field direction change data of the normal magnetoresistive sensing device from the various magnetic field direction change data; determining the first resistance change value based on the magnetic field direction change data of the normal magnetoresistive sensing device, and detecting the wearing status of the target smart device based on the first resistance change value.

[0073] It should be understood that if any data in the various magnetic field direction change data does not meet the preset change conditions, it indicates that at least one magnetoresistive sensing device is malfunctioning. In this case, it is necessary to perform fault detection on multiple magnetoresistive sensing devices separately to distinguish between faulty magnetoresistive sensing devices and normal magnetoresistive sensing devices.

[0074] Understandably, in order to effectively improve the accuracy of detecting the wearing status of the target smart device, this embodiment uses the magnetic field direction change data of the normal magnetoresistive sensor closest to the magnet assembly to determine the resistance change value. When it is determined that the distance between the faulty magnetoresistive sensor and the magnet assembly is greater than or equal to the distance between the normal magnetoresistive sensor and the magnet assembly, it indicates that the normal magnetoresistive sensor is closest and in a normal state. At this time, the magnetic field direction change data of the normal magnetoresistive sensor is selected from the various magnetic field direction change data, and the first resistance change value is determined based on the magnetic field direction change data of the normal magnetoresistive sensor. The number of magnetic pole increases is determined based on the first resistance change value. The number of magnetic pole increases is converted into a corresponding wearing status recognition signal through the signal processing circuit, which is used to identify the opening and closing angle of the temples, thereby detecting the wearing status of the target smart device.

[0075] Furthermore, after the step of determining the faulty magnetoresistive sensing device and the normal magnetoresistive sensing device based on the fault detection result, the method further includes: when the distance between the faulty magnetoresistive sensing device and the magnet assembly is less than the distance between the normal magnetoresistive sensing device and the magnet assembly, acquiring the location information of the faulty magnetoresistive sensing device on the target smart device; generating device fault prompt information based on the location information, and displaying the device fault prompt information on a terminal connected to the target smart device; determining a second resistance change value based on the distance between the normal magnetoresistive sensing device and the magnet assembly, the distance between the faulty magnetoresistive sensing device and the magnet assembly, and the magnetic field direction change data of the normal magnetoresistive sensing device, and detecting the wearing status of the target smart device based on the second resistance change value.

[0076] It is understandable that when the distance between the faulty magnetoresistive sensing device and the magnet assembly is less than the distance between the normal magnetoresistive sensing device and the magnet assembly, it indicates that the faulty magnetoresistive sensing device is relatively close, but it is in a faulty state. At this time, the magnetic field direction change data of the faulty magnetoresistive sensing device is unavailable. Based on the location information, a device fault prompt message is generated and displayed on the terminal connected to the target smart device to prompt professional personnel to replace the faulty magnetoresistive sensing device.

[0077] It should be noted that, in order to detect the wearing status of the target smart device even when the magnetoresistive sensing device is faulty, this embodiment sets up multiple magnetoresistive sensing devices on the target smart device and activates multiple magnetoresistive sensing devices simultaneously to detect the wearing status. Since the normal magnetoresistive sensing device is far away, there will be errors if the magnetic field direction change data of the normal magnetoresistive sensing device is used directly for detection. In order to effectively improve the accuracy of detecting the wearing status of the target smart device, the magnetic field direction change data of the faulty magnetoresistive sensing device is predicted based on the distance between the normal magnetoresistive sensing device and the magnet assembly, the distance between the faulty magnetoresistive sensing device and the magnet assembly, and the magnetic field direction change data of the normal magnetoresistive sensing device. At this time, the second resistance change value can be determined based on the magnetic field direction change data of the faulty magnetoresistive sensing device, and then the number of magnetic poles increased is determined based on the second resistance change value. The number of magnetic poles increased is converted into a corresponding wearing status recognition signal by the signal processing circuit, which is used to identify the opening and closing angle of the temples, and thus detect the wearing status of the target smart device.

[0078] Step S40: When all the magnetic field direction change data meet the preset change conditions, the wearing status of the target smart device is detected based on the target data in each of the magnetic field direction change data.

[0079] Understandably, when the data on changes in all magnetic field directions meet the preset conditions, it indicates that all magnetoresistive sensing devices are functioning correctly. In this case, to effectively improve the accuracy of detecting the wearing status of the target smart device, the magnetic field direction change data from the nearest magnetoresistive sensing device is extracted from the data on changes in all magnetic field directions to detect the wearing status of the target smart device. Alternatively, the magnetic field direction change data from a more distant magnetoresistive sensing device can also be used to verify the wearing status.

[0080] Furthermore, after step S40, the method further includes: when the wearing state is an unwearing state, triggering the sleep function of the target smart device according to a device sleep command; when the wearing state is a fully worn state, triggering the wake-up function of the target smart device according to a device wake-up command; when the wearing state is a half-wearing state, acquiring the user's image information through a camera device installed on the target smart device, and extracting the feature information of the image information; when the feature information exists in the historical feature database, searching for target interaction data specific to the user based on the feature information; and interacting with the user based on the target interaction data.

[0081] It should be understood that the wearing state in this embodiment is divided into three types: not wearing, fully wearing, and partially wearing. The partially wearing state refers to the state where the user has not correctly worn the target smart device, such as wearing it without fully opening the temples or wearing it with an incorrect head size. The partially wearing state can also be divided into large-angle partially wearing and small-angle partially wearing states. When the wearing state is "not wearing," it indicates that the user is not wearing the target smart device. In this case, the device's sleep function can be triggered according to the device's sleep command, putting the target smart device into a sleep state. When the wearing state is "fully wearing," it indicates that the user has correctly worn the target smart device. In this case, the device's wake-up function can be triggered according to the device's wake-up command, putting the target smart device into a working state.

[0082] Understandably, when the wearing status is determined to be in a half-wearing state, it indicates that the user is not wearing the target smart device correctly. In this case, in order to improve the user experience, it is necessary to collect the user's image information and, if the feature information exists in the historical feature database, search for the target interaction data that is unique to the user based on the feature information. This target interaction data can be images, text, etc. The application displaying this target interaction data has low power consumption and consumes less electricity.

[0083] It should be noted that this embodiment will also provide feedback to the R&D team on the outward tilt angle of the target smart device under different wearing conditions, thereby obtaining real user data feedback, which will facilitate subsequent product development and the organization of user profile data.

[0084] This embodiment acquires the current temperature of a magnet assembly mounted on a target smart device and determines the current magnetic field strength of the magnet assembly based on the current temperature. When the current magnetic field strength does not meet a preset strength condition, the current temperature is adjusted by a temperature adjustment component corresponding to the magnet assembly. The current angles between multiple magnetoresistive sensors mounted on the target smart device and the magnet assembly are detected, and magnetic field direction change data is determined based on the current angles. A relative rotational relationship exists between the multiple magnetoresistive sensors and the magnet assembly. When all the magnetic field direction change data meet the preset change condition, the wearing status of the target smart device is detected based on the target data in each of the magnetic field direction change data. By using the temperature adjustment component to ensure that the magnetic field strength of the magnet assembly meets the preset strength condition, and then using the magnetic field direction change data detected by multiple magnetoresistive sensors to determine the wearing status of the target smart device, the accuracy and sensitivity of the wearing status detection can be effectively improved, while reducing detection costs and latency.

[0085] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 Step S40 includes steps S401 to S404:

[0086] Step S401: When all the magnetic field direction change data meet the preset change conditions, the distance between each magnetoresistive sensing device and the magnet assembly is detected respectively.

[0087] It should be noted that when the data changes in each magnetic field direction meet the preset change conditions, it indicates that all magnetoresistive sensing devices are normal. At this time, the distance between each magnetoresistive sensing device and the magnet assembly is measured to determine the magnetoresistive sensing device closest to the magnet assembly.

[0088] Step S402: Select target data from the various magnetic field direction change data according to the distance.

[0089] Understandably, the target data refers to the magnetic field direction change data of the magnetoresistive sensing device closest to the magnet assembly. After detecting the distance between each magnetoresistive sensing device and the magnet assembly, the magnetoresistive sensing device closest to the magnet assembly is determined, and the magnetic field direction change data of the magnetoresistive sensing device closest to the magnet assembly is selected from the various magnetic field direction change data, which is the target data.

[0090] Step S403: Determine the target resistance change value based on the target data, and generate a wearing status identification signal based on the target resistance change value.

[0091] It should be understood that the target resistance change value refers to the value of the resistance change caused by the change in the relative angle between the magnetoresistive sensing device closest to the magnet assembly and the magnet assembly. The wearing status recognition signal refers to the signal used to identify the wearing status of the target smart device. After determining the target resistance change value, the number of magnetic poles is determined based on the target resistance change value. The number of magnetic poles is converted into the corresponding wearing status recognition signal through the signal processing circuit. The magnet assembly is turned on 5 times and off 5 times per cycle, with an angular resolution of 36°.

[0092] Step S404: Detect the wearing status of the target smart device based on the wearing status recognition signal.

[0093] It is understandable that the wearing status refers to the state of the user wearing the smart device at the current moment. After generating the wearing status recognition signal based on the target resistance change value, the wearing status of the target smart device is detected based on the wearing status recognition signal.

[0094] In this embodiment, when all the magnetic field direction change data meet preset change conditions, the distance between each magnetoresistive sensing device and the magnet assembly is detected; target data is selected from the magnetic field direction change data based on the distance; a target resistance change value is determined based on the target data, and a wearing status recognition signal is generated based on the target resistance change value; the wearing status of the target smart device is detected based on the wearing status recognition signal. By using the above method, when all the magnetic field direction change data meet preset change conditions, the magnetic field direction change data of the magnetoresistive sensing device closest to the magnet assembly is selected from the magnetic field direction change data, and the wearing status of the target smart device is detected based on the wearing status recognition signal, thereby effectively improving the accuracy of wearing status detection.

[0095] This application also provides a wearing status detection device, please refer to... Figure 4 The wearing status detection device includes:

[0096] The acquisition module 10 is used to acquire the current temperature of the magnet assembly set on the target smart device, and determine the current magnetic field strength of the magnet assembly based on the current temperature.

[0097] The adjustment module 20 is used to adjust the current temperature by means of a temperature adjustment component corresponding to the magnet assembly when the current magnetic field strength does not meet the preset strength condition.

[0098] The determining module 30 is used to detect the current angle between the multiple magnetoresistive sensing devices installed on the target smart device and the magnet assembly, and to determine the magnetic field direction change data based on the current angle; wherein, there is a relative rotational relationship between the multiple magnetoresistive sensing devices and the magnet assembly.

[0100] This embodiment acquires the current temperature of a magnet assembly mounted on a target smart device and determines the current magnetic field strength of the magnet assembly based on the current temperature.
