[0001] This invention relates to the field of smart glasses, and in particular to a smart pair of glasses, a method for detecting the wearing of smart glasses, and an electronic device. Background Technology

[0002] Currently, wear detection in smart glasses typically supports this function, controlling the glasses' automatic sleep and operation by detecting whether the user is wearing them. Existing technologies usually rely on proximity sensors or capacitive sensors for wear detection. However, proximity sensors are prone to false triggering when the sensor's opening is blocked by a hand or dirt, even when the glasses are not worn on the head. Similarly, capacitive sensors can be triggered by sweat, causing the glasses to wake up unnecessarily, impacting user experience and standby time. Summary of the Invention

[0003] The main objective of this invention is to propose a smart glasses, a method for detecting the wearing of smart glasses, and an electronic device, aiming to solve the problem that the detection of smart glasses wearing is easily triggered by external factors.

[0004] To achieve the above objectives, the present invention proposes smart glasses, the smart glasses comprising: nose pads; A sensor, mounted on the nose pad, is used to output human body parameter acquisition signals; A control unit, connected to the sensor, is used to determine whether the smart glasses are being worn by the user based on received human body parameter acquisition signals.

[0005] Optionally, the sensor is a respiratory rate sensor, and the human body parameter acquisition signal includes respiratory acquisition parameters; The respiratory rate sensor is connected to the control unit and is used to output respiratory acquisition parameters; The control unit is specifically used to match the respiratory acquisition parameters with preset respiratory parameters, and determine whether the smart glasses are worn by the user based on the matching result.

[0006] Optionally, the control unit is specifically used to calculate the current matching degree between the respiratory acquisition parameters and the preset respiratory parameters according to the matching degree formula, and compare the current matching degree with the matching degree threshold to determine whether the smart glasses are worn by the user.

[0007] Optionally, the respiratory acquisition parameters include the current respiratory time, the current inspiratory time, the current respiratory cycle value, the current expiratory amplitude, and the current inspiratory amplitude; The control unit is specifically used to calculate the current matching degree by combining the current exhalation time, the current inhalation time, the current respiratory cycle value, the current exhalation amplitude, and the current inhalation amplitude with the preset exhalation time, the preset inhalation time, the preset inhalation time, the preset respiratory cycle value, and the preset exhalation amplitude preset respiratory parameters according to the matching degree formula.

[0008] Optionally, the respiratory acquisition parameters include average expiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, and average inspiratory amplitude. The control unit is also used to obtain the average respiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, and average inspiratory amplitude within a preset time period, and to calculate the current matching degree by comparing the average respiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, average inspiratory amplitude, and current inspiratory amplitude with the preset expiratory time, preset respiratory time, preset inspiratory time, preset respiratory cycle value, and preset expiratory amplitude preset respiratory parameters according to the matching degree formula.

[0009] Optionally, the sensor is a distance sensor and / or the sensor is a capacitive sensor.

[0010] Optionally, the nose pad includes a left nose pad and a right nose pad, and the sensor is disposed on the left nose pad and / or the right nose pad.

[0011] Optionally, the control unit includes: Controller; An analog-to-digital conversion module is electrically connected to the sensor and is used to convert the received human body parameter acquisition signal into an analog-to-digital signal and then output it. The microprocessor is electrically connected to both the analog-to-digital conversion module and the controller. The microprocessor is used to determine whether the smart glasses are being worn by the user based on the received human body parameter acquisition signal after analog-to-digital conversion, so as to trigger the controller to enter a working / sleep state.

[0014] The technical solution of this invention places the sensor on the nose pad, so that when the user picks up the smart glasses by folding the temples together or holding the temples with both hands, the sensor will not be directly in contact with the user due to its placement on the temples. Because the nose pad and temples are not directly adjacent, the user is less likely to touch the nose pad when picking up the glasses, thus minimizing the possibility of the sensor being accidentally triggered due to the user's palm touching the sensor.

[0022] This invention proposes a smart glasses.

[0023] Reference Figure 1 and Figure 6 In one embodiment, the smart glasses include: Nose pad 10; Sensor 20 is disposed on the nose pad 10 and is used to output human body parameter acquisition signals; Control unit 30, which is connected to sensor 20, is used to determine whether the smart glasses are being worn by the user based on the received human body parameter acquisition signals.

[0024] In this embodiment, the sensor 20 can be a distance sensor 20, a capacitance sensor 20, or a respiratory rate sensor 21, etc.

[0025] Optionally, the nose pads 10 are usually a pair, including a left nose pad and a right nose pad. When there is one sensor 20, it can be set on the left nose pad or the right nose pad. When there are two sensors 20, they can be set on the left nose pad and the right nose pad respectively.

[0026] Understandably, wear detection in smart glasses is typically based on a distance sensor 20 or a capacitive sensor 20, which are usually located on the temples. During wear detection, the user's scalp is pressed against the temples, either blocking the light / sound waves emitted by the distance sensor 20 or altering the capacitance value output by the capacitive sensor 20, thus detecting the object's distance. However, when users pick up the glasses, they often fold the temples, hold both temples together, or hold each temple with both hands. This can cause the emitted light / sound waves to be blocked or the output capacitance value to change during the process of being picked up, leading to the smart glasses being falsely triggered and ending their sleep state even before being worn by the user.

[0027] Therefore, in this embodiment, the sensor 20 is placed on the nose pad 10, so that when the user picks up the smart glasses by folding the temples together or holding the temples separately with both hands, the sensor 20 will not be directly contacted because it is placed on the temples. Since the nose pad 10 is not directly adjacent to the temples, the user will not easily touch the nose pad 10 when picking it up, thus minimizing the possibility of the smart glasses being falsely triggered due to the palm touching the sensor 20. In situations such as when the user is tidying up the room, and the smart glasses are picked up but not worn, the user's palm will pick up the smart glasses by touching the temples, but will not directly touch the nose pad 10. Since the sensor is placed on the nose pad 10, the nose pad 10 cannot collect human body parameter information. Therefore, the control unit 30 will not determine that the smart glasses are being worn based on the received human body parameter collection signal, thus keeping the smart glasses in a dormant state and preventing the sensor 20 from being falsely triggered due to the palm being blocked.

[0028] Specifically, during normal wear detection of the smart glasses, sensor 20 continuously monitors the human body at the nose pad 10. When a user puts on the smart glasses, sensor 20, located at the nose pad 10, will be in close contact with the user's nose, collecting human body parameter information at the nose pad 10 and outputting the corresponding human body parameter collection signal. Based on the received human body parameter collection signal, control unit 30 determines that the smart glasses are being worn, thus entering working mode and controlling the display screen to light up. Specifically, when determining whether the smart glasses are being worn based on the received human body parameter collection signal, control unit 30 can set a preset parameter range. When control unit 30 determines that the current human body parameters at the nose pad 10 are within the preset parameter range, it determines that the smart glasses are being worn.

[0029] This invention places the sensor 20 on the nose pad 10, ensuring that when the user holds the smart glasses by folding the temples together or holding the temples separately, the sensor 20 will not be directly contacted due to its placement on the temples. Because the nose pad 10 is not directly adjacent to the temples, the user is less likely to touch it, minimizing the possibility of the sensor 20 being accidentally triggered by a hand touching it.

[0030] Reference Figure 2 and Figure 6 In one embodiment, the sensor 20 is a respiratory rate sensor 21, and the human body parameter acquisition signal is a respiratory acquisition parameter; The respiratory rate sensor 21 is connected to the control unit 30 and is used to output respiratory acquisition parameters; The control unit 30 is specifically used to match the respiratory acquisition parameters with preset respiratory parameters, and determine whether the smart glasses are worn by the user based on the matching result.

[0031] It should be noted that each nose pad 10 is provided with a nose pad silicone. The breathing rate sensor 21 can be placed inside the nose pad silicone and connected to the control unit 30 of the smart glasses via a signal line, or it can be placed on the side of the nose pad silicone that is in contact with the nose wing.

[0032] In this embodiment, the respiratory acquisition parameters can be the respiratory frequency, or specific parameters such as respiratory amplitude, inhalation time, and exhalation time; the preset respiratory range is set by the designer based on multiple sets of human test results when designing the smart glasses, such as the respiratory frequency can be set to 12~20 breaths / minute.

[0033] During normal wear detection of the smart glasses, the respiratory rate sensor 21 detects human breathing information at the nose pad 10 in real time. When the user puts on the smart glasses, the respiratory rate sensor 21 will be in close contact with the user's nose, collecting the vibration of the user's nose caused by breathing and outputting the corresponding respiratory collection parameters. The control unit 30 has a preset breathing range. Therefore, when the control unit 30 matches the received respiratory collection parameters with the preset breathing range, it can detect that the respiratory collection parameters are within the preset breathing range, determine that the smart glasses are being worn, and thus be triggered to enter the working state and control the display screen to light up.

[0034] When the smart glasses are not being worn, the breathing rate sensor 21 cannot collect breathing information at the nose pad 10. Therefore, the breathing collection parameters received by the control unit 30 will be much lower than the preset breathing range, thus determining that the smart glasses are not being worn and thus maintaining a sleep state, and the display screen remains off.

[0035] This invention collects the user's breathing information by setting a respiratory rate sensor 21 and outputs it to a microprocessor 31. The microprocessor 31 detects the current wearing status of the smart glasses based on the received breathing parameters and triggers the control unit 30 to enter a working / sleep state based on the detection result, thereby controlling the load to work / stop. This utilizes the respiratory rate sensor 21 to detect the human body's breathing characteristics, thus realizing the detection of whether the smart glasses are being worn. Because human breathing characteristics are relatively stable and a matching algorithm is incorporated, the detection results are less susceptible to interference from bodily fluids or environmental factors, improving detection accuracy.

[0036] Reference Figure 3 , Figure 6 and Figure 7 In one embodiment, the control unit 30 is specifically used to calculate the current matching degree between the respiratory acquisition parameters and the preset respiratory parameters according to the matching degree formula, and compare the current matching degree with the matching degree threshold to determine whether the smart glasses are worn by the user.

[0037] In this embodiment, the matching degree threshold is set by the R&D personnel based on multiple sets of human test results. The matching degree threshold is the critical value when the respiratory acquisition parameters are matched with the preset respiratory parameters. When the current matching degree exceeds the critical value, it is considered that the glasses are being worn. The value of the critical value can be 45%, 55%, 65%, etc.

[0038] It should be noted that the respiratory rate sensor 21 converts the human breathing process into... Figure 7 The voltage waveform shown is transmitted to the control unit 30, which then detects the current wearing status of the smart glasses based on the corresponding voltage waveform. Since everyone's breathing process has subtle differences, it is necessary to match key parameters such as breathing frequency with a standard matching threshold using a matching degree formula. When the matching degree is greater than the matching threshold, the glasses are considered to be worn.

[0039] After receiving the respiratory acquisition parameters, the control unit 30 performs algorithmic analysis on the voltage waveform, such as determining the current respiratory rate based on the amplitude of the voltage signal waveform and the respiratory rate based on the frequency of the voltage signal waveform, and sets a matching degree threshold Q. If the matching degree is greater than or equal to Q, it is considered that the glasses are worn on the body, and the control unit 30 interrupts its sleep mode and starts working, and lights up the screen. During operation, the control unit 30 monitors the respiratory rate data in real time and calculates the matching degree. If the matching value is less than the threshold Q, it is considered that the glasses have been removed, and the control unit 30 controls the screen to turn off and enters sleep mode to save power.

[0040] Reference Figure 3 , Figure 6 and Figure 8 In one embodiment, the respiratory acquisition parameters include the current respiratory time, the current inspiratory time, the current respiratory cycle value, the current expiratory amplitude, and the current inspiratory amplitude; The control unit 30 is specifically used to calculate the current matching degree by combining the current exhalation time, the current inhalation time, the current respiratory cycle value, the current exhalation amplitude, and the current inhalation amplitude with the preset exhalation time, the preset inhalation time, the preset inhalation time, the preset respiratory cycle value, and the preset exhalation amplitude preset respiratory parameters according to the matching degree formula.

[0041] In this embodiment, as Figure 8 As shown, after the respiratory sensor 20 outputs the collected respiratory parameters in the form of a voltage waveform, the control unit 30 quantifies the output voltage waveform to obtain the respiratory time, inspiratory time, respiratory cycle, expiratory amplitude, and inspiratory amplitude.

[0042] Furthermore, considering the subtle differences in each person's breathing process, this embodiment uses a weighted matching method for breathing time, inhalation time, respiratory cycle, expiratory amplitude, and inhalation amplitude. When the matching degree is greater than a set threshold, the glasses are considered to be worn. For example, suppose that the data detected by sensor 20 in a certain instance is the current breathing time t1, current inhalation time t2, current respiratory cycle t, current expiratory amplitude a, and current inhalation amplitude b. The standard breathing time for a human body is a preset breathing time T1, preset inhalation time T2, preset respiratory cycle T, preset expiratory amplitude A, and preset inhalation amplitude B. Then, the matching degree q of the detected values ​​can be calculated using the following formula: q + + ) W+ P] 100%; And P+W=100%; X+Y+Z+U=100%. Where X is the proportion of the expiratory time matching parameter, Y is the proportion of the inspiratory time matching parameter, Z is the proportion of the expiratory amplitude matching parameter, U is the proportion of the inspiratory amplitude matching parameter, W is the proportion of the total respiratory matching parameter, and P is the proportion of the respiratory cycle matching parameter.

[0043] It is understandable that the control unit 30 has a pre-stored range of parameter values. Breathing acquisition parameter values ​​that exceed the range will be discarded. Then, by weighting the proportion of different breathing acquisition parameters according to the matching formula, a matching value q is obtained. When q is greater than or equal to Q, it is determined that the smart glasses are in the wearing state, the control unit 30 interrupts sleep mode, and controls the display to light up.

[0044] Reference Figure 3 , Figure 6 and Figure 8 In one embodiment, the respiratory acquisition parameters include average expiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, and average inspiratory amplitude. The control unit 30 is further configured to obtain the average respiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, and average inspiratory amplitude within a preset time period, and to calculate the current matching degree by comparing the average respiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, average inspiratory amplitude, and current inspiratory amplitude with the preset expiratory time, preset respiratory time, preset inspiratory time, preset respiratory cycle value, and preset expiratory amplitude preset respiratory parameters according to the matching degree formula.

[0045] It should be noted that human breathing is not always consistent. People may take deep breaths when tired or hold their breath when they smell an odor. Therefore, it is often inaccurate to collect breathing data only within a single cycle.

[0046] In this embodiment, a preset time period is pre-stored in the control unit 30. When the respiratory rate sensor 21 is working, the control unit 30 processes the received respiratory acquisition parameters in a preset time period. By analyzing the voltage signal waveform within the preset time period, the average respiratory time, average inspiratory time, average respiratory cycle value, average expiratory amplitude, and average inspiratory amplitude within the preset time period are obtained. An algorithmic analysis is then performed on the average respiratory acquisition parameters within the preset time period. If the matching degree is greater than or equal to Q, it is considered that the glasses are worn on the body, and the control unit 30 interrupts its sleep state and begins working, turning on the screen. During operation, the control unit 30 continuously monitors the respiratory rate data and calculates the matching degree. If the matching value is less than the threshold Q, it is considered that the glasses have been removed, and the control unit 30 controls the screen to turn off and enters a sleep state to save power.

[0047] Reference Figure 1 and Figure 6 In one embodiment, the sensor 20 is a distance sensor 20 and / or the sensor 20 is a capacitive sensor 20.

[0048] In this embodiment, the distance sensor 20 is electrically connected to the microprocessor 31 and is used to collect the distance between the nose pad 10 and the human body, and output the corresponding distance acquisition signal; the capacitance sensor 20 is electrically connected to the microprocessor 31 and is used to output the corresponding capacitance acquisition signal according to whether it is in contact with the human body.

[0049] When the sensor 20 is a distance sensor 20, the microprocessor 31 is used to determine the current wearing parameters based on the received parameter acquisition signal, match the detected current wearing parameters with preset parameters, and control the load to work / stop working based on the matching result.

[0050] When the sensor 20 is a distance sensor 20, the microprocessor 31 is specifically used to determine the current human body distance based on the received distance acquisition signal, match the detected current human body distance with a preset distance, and control the load to work / stop working based on the matching result.

[0051] Reference Figure 3 , Figure 4 In one embodiment, the control unit 30 includes: Controller 32; Analog-to-digital conversion module 40, which is electrically connected to the sensor 20, is used to convert the received human body parameter acquisition signal into analog and digital signals and then output it. The microprocessor 31 is electrically connected to the analog-to-digital conversion module 40 and the controller 32 respectively. The microprocessor 31 is used to determine whether the smart glasses are being worn by the user based on the received human body parameter acquisition signal after analog-to-digital conversion, so as to trigger the controller 32 to enter the working / sleep state.

[0052] It should be noted that existing smart glasses typically include a microprocessor 31 and a controller 32. The controller 32 is the main power-consuming component of the smart glasses, while the microprocessor 31 consumes less power when it is working. Therefore, when the smart glasses are not worn, the controller 32 will control the high-power load such as the display screen to stop working, leaving the microprocessor 31 to receive the acquisition signals output by the sensor 20 in real time to detect the wearing status of the smart glasses, so as to trigger the controller 32 to work in time when it is detected that the user is wearing the glasses.

[0053] In this embodiment, when the smart glasses are being worn normally, sensor 20 connects the respiratory rate sensor 21 to the analog-to-digital converter module 40, digitizes the analog voltage signal, and then transmits the digital signal to the microprocessor 31. The microprocessor 31 receives the respiratory acquisition parameters output by the respiratory rate sensor 21 in real time. After receiving the respiratory acquisition parameters, it performs algorithmic analysis on the human respiratory acquisition parameters to obtain a matching degree q. Furthermore, the microprocessor 31 has a matching degree threshold Q. If the matching degree q is greater than or equal to the matching degree threshold Q, it indicates that the smart glasses are worn on the human body. At this time, the microprocessor 31 sends an interrupt signal to wake up the controller 32, causing the controller 32 to enter the working state and turn on the screen. If the matching value q is less than the threshold Q, it indicates that the smart glasses are not worn. At this time, the microprocessor 31 outputs a sleep signal to trigger the controller 32 to enter the sleep state to save power.

[0054] Optionally, in some embodiments, the microprocessor 31 may also select a control chip with ADC function, so that the analog-to-digital conversion module 40 is integrated inside the microprocessor 31.

[0055] Reference Figure 1 In one embodiment, the smart glasses further include: Temples; The sensor 20 is disposed on the temple of the mirror.

[0056] In this embodiment, a pulse sensor 22 can also be used on the temple, or it can be used in combination with the breathing sensor 20 and pulse sensor 22 at the nose pad 10, while the previous distance sensor 20 and capacitance sensor 20 are retained on the temple.

[0057] When the pulse sensor 22 is used on the temple of the glasses, it detects the pulse parameters at the temple in real time. When the user wears the smart glasses, the pulse sensor 22 on the temple will be in close contact with the user's temple to collect the pulse of the head and output the corresponding pulse collection signal. The controller 32 has a preset pulse range. Therefore, when the controller 32 obtains the current pulse parameters at the temple based on the received pulse collection signal and matches the current pulse parameters with the preset pulse range, it can detect that the current pulse parameters are within the preset pulse range, determine that the smart glasses are being worn, and thus output an interrupt signal to the processor. This triggers the processor to enter the working state and controls the display screen to light up.

[0058] It should be noted that the preset pulse range is set by the designers based on multiple sets of human test results when designing the smart glasses, and can be 60-100 beats / minute, etc. Therefore, if the smart glasses are mistakenly worn by pets or other living beings, the processor will not output an interrupt signal and will remain in sleep mode because the detected current pulse parameters are not within the preset pulse range.

[0059] When the smart glasses are not being worn, the pulse sensor 22 cannot collect pulse information at the temple. Therefore, when the controller 32 obtains the current pulse parameters from the pulse acquisition signal, the current pulse parameters will be much lower than the preset pulse range, thus determining that the smart glasses are not being worn and will not output an interrupt signal, keeping the processor in sleep mode and the display screen off.

[0060] Because of the relatively stable characteristics of the human pulse and the integration of a matching algorithm, the detection results are less susceptible to interference from bodily fluids or environmental factors, thus improving detection accuracy. This reduces the likelihood of accidental touches affecting the smart glasses' standby time without requiring changes to the sensor's position.

[0061] Furthermore, since the distance sensor 20 and the capacitive sensor 20 do not require weighted analysis of the voltage waveform output by the sensor 20 when collecting human body parameters, their calculation speed is often faster than that of the breathing sensor 20. Therefore, when combined with the breathing sensor 20 and pulse sensor 22 at the nose pad 10, and retaining the distance sensor 20 and capacitive sensor 20 on the temples, different priorities can be set according to the user's usage habits. For example, if the user is used to running at night, the capacitive sensor 20 is more susceptible to interference from sweat between 8 pm and 10 pm. Therefore, the sensor 20 at the nose pad 10 can be set to the highest priority between 8 pm and 10 pm to prevent the smart glasses from being falsely triggered by external interference. At other times, the capacitive sensor 20 at the temples can be set to the highest priority so that the smart glasses can quickly enter sleep or working state when they are not affected by sweat.

[0062] The user's usage habits can be determined by the user manually inputting information through interactive components such as the display screen, or by setting a water immersion sensor 20 on the temple of the glasses. Based on the liquid collection signal output by the water immersion sensor 20, the user can determine when they will sweat profusely.

[0063] Reference Figures 1 to 10 In one embodiment, the smart glasses include a nose pad 10 and a sensor 20 disposed on the nose pad 10; The method for detecting the wearing of smart glasses includes the following steps: S100. Determine the respiratory acquisition parameters based on the received respiratory acquisition parameters; S200. Match the respiratory acquisition parameters with preset respiratory parameters to determine whether the smart glasses are being worn by the user based on the matching result.

[0064] In this embodiment, the respiratory acquisition parameters can be the respiratory frequency, or specific parameters such as respiratory amplitude, inhalation and exhalation time; the preset respiratory range is set by the designer based on multiple sets of human test results when designing the smart glasses, such as the respiratory frequency can be set to 12~20 breaths / minute.

[0065] During normal wear detection of the smart glasses, the respiratory rate sensor 21 continuously monitors the respiratory parameters collected at the nose pad 10. When the user puts on the smart glasses, the respiratory rate sensor 21 is in close contact with the user's nose, collecting the vibrations of the user's nose caused by breathing and outputting the corresponding respiratory parameters. The control unit 30 has a preset breathing range. Therefore, when the control unit 30 obtains the respiratory parameters collected at the nose pad 10 based on the received respiratory parameters and matches the respiratory parameters with the preset breathing range, it can detect that the respiratory parameters are within the preset breathing range, determine that the smart glasses are being worn, and thus be triggered to enter the working state and control the display screen to light up.

[0066] When the smart glasses are not being worn, the respiratory rate sensor 21 cannot collect respiratory information at the nose pad 10. Therefore, when the control unit 30 obtains respiratory collection parameters, the respiratory collection parameters will be much lower than the preset respiratory range, thus determining that the smart glasses are not being worn and thus maintaining a sleep state, and the display screen remains off.

[0067] This invention collects the user's breathing information by setting a respiratory rate sensor 21 and outputs it to a microprocessor 31. The microprocessor 31 detects the current wearing status of the smart glasses based on the received breathing parameters and triggers the control unit 30 to enter a working / sleep state based on the detection result, thereby controlling the load to work / stop. This utilizes the respiratory rate sensor 21 to detect the human body's breathing characteristics, thus realizing the detection of whether the smart glasses are being worn. Because human breathing characteristics are relatively stable and a matching algorithm is incorporated, the detection results are less susceptible to interference from bodily fluids or environmental factors, improving detection accuracy.
