[0035] The ear loop b is located on the side of the main body a of each temple 200 away from the frame 100 and is connected to the main body a of each temple 200. Specifically, the ear loop b of the first temple 210 is connected to the main body a of the first temple 210, and the ear loop b of the second temple 250 is connected to the main body a of the second temple 250. In some other embodiments, the ear loop b may include an extension structure located on the side of the ear support c closer to the frame. The extension structure and the ear support correspond to the front and back sides of the user's ear, respectively, and this application does not impose any limitations on this.
[0036] The ear support c is connected to the end of the ear loop b of the temple 200 away from the main body a. There are two ear supports c: a first ear support 215 and a second ear support 255. The first ear support 215 is located at the end of the ear loop b of the first temple 210 away from the frame 100 and is connected to the ear loop b of the first temple 210, used to further secure the smart glasses 1000 tightly to the user's ear and prevent the smart glasses 1000 from slipping off. The second ear support 255 is located at the end of the ear loop b of the second temple 250 away from the frame 100 and is connected to the ear loop b of the second temple 250, used to further secure the smart glasses 1000 tightly to the user's ear and prevent the smart glasses 1000 from slipping off.
[0037] Along the length of the frame 100, the nose pads 300 are located in the middle of the frame 100, spaced apart from the temples 200, and connected to the frame 100. There are two nose pads 300, including a first nose pad 310 and a second nose pad 350. The second nose pad 350 is located on the side of the first nose pad 310 away from the first temple 210, and is opposite to and spaced apart from the first nose pad 310.
[0038] The lens 400 is located between the nose pad 300 and the temple 200 and is mounted on the frame 100. There are two lenses 400, which are spaced apart. One lens 400 is located between the first temple 210 and the first nose pad 310, and the other lens 400 is located between the second temple 250 and the second nose pad 350.
[0039] The smart glasses 1000 also includes multiple EEG acquisition electrodes Q and sensory stimulation components. All EEG acquisition electrodes Q and sensory stimulation components are located on the frame A. The multiple EEG acquisition electrodes Q are spaced apart and used to acquire the user's EEG signals. At least one EEG acquisition electrode Q is located on the ear hook b. Specifically, the multiple EEG acquisition electrodes Q include at least one active electrode 700, at least one reference electrode 500, and at least one ground electrode 600. At least one active electrode 700 is located on the ear hook b, and at least one reference electrode 500 is located on the ear support c or nose pad 300.
[0040] In this embodiment, there are 2N active electrodes 700, where N is a positive integer. The 2N active electrodes 700 are symmetrically arranged on the frame A. Specifically, N active electrodes 700 are located on the ear loops b of the first temple 210 and the first nose pad 310, and the other N active electrodes 700 are located on the ear loops b of the second temple 250 and the second nose pad 350. For example, N is 3, meaning there are 6 active electrodes 700. Four active electrodes 700 are symmetrically arranged on the ear loops b of the first temple 210 and the second temple 250, corresponding to the left and right periauricular regions of the user's brain, respectively, to collect temporal lobe EEG signals. The other two active electrodes 700 are symmetrically arranged on the first nose pad 310 and the second nose pad 350. In some other embodiments, the 2N active electrodes 700 may be symmetrically arranged only on the ear-hook portion b of the first temple 210 and the ear-hook portion b of the second temple 250, that is, N active electrodes 700 are arranged on the first temple 210 and the other N active electrodes 700 are arranged on the second temple 250. Alternatively, the 2N active electrodes 700 may be asymmetrically arranged on the frame A. This application does not limit this. In some other embodiments, the active electrodes 700 may also be arranged on the extension structure of the ear-hook portion b for collecting electroencephalogram (EEG) signals from the periphery of the user's ear. This application does not limit this.
[0041] In this embodiment, there are two reference electrodes 500. The two reference electrodes 500 are symmetrically arranged on the frame A. One reference electrode 500 is located on the first ear support 215, corresponding to the user's left mastoid process, to collect EEG signals from the user's left side. The other reference electrode 500 is located on the second ear support 255, corresponding to the user's right mastoid process, to collect EEG signals from the user's right side. It should be noted that the reference electrodes 500 are typically positioned at locations corresponding to the body's zero-potential points, such as the earlobe, nose tip, and mastoid process, so that the potential collected by the reference electrodes 500 can provide a stable reference potential for the active electrode 700, thereby making the measurement of EEG signals more accurate. Therefore, in this embodiment, the reference electrode 500 is located on the ear support c. In some other embodiments, the two reference electrodes 500 may also be symmetrically arranged on the first nose pad 310 and the second nose pad 350; this application does not impose any limitations on this.

This application does not limit this.
[0042] The grounding electrode 600 is located on the ear support c of the eyeglass frame A, on the side of the reference electrode 500 away from the ear hook b, and is spaced apart from both the reference electrode 500 and the active electrode 700. The grounding electrode 600 and the active electrode 700 do not interfere with each other. It should be noted that the grounding electrode 600 and the reference electrode 500 do not interfere with each other through a rationally designed functional partition, electrical isolation, appropriate layout, and noise suppression measures, thus avoiding electrical interference between them and ensuring accurate signal acquisition and processing. In this embodiment, there are two grounding electrodes 600. The two grounding electrodes 600 are symmetrically arranged on the eyeglass frame A. One grounding electrode 600 is located on the first ear support 215, and the other grounding electrode 600 is located on the second ear support 255.

In some other embodiments, the grounding electrode 600 may also be located at the end of the eyeglass frame A away from the active electrode 700; this application does not limit this. In some other embodiments, the grounding electrode 600 may be asymmetrically arranged on the frame A, or there may be only one grounding electrode 600. This application does not limit this.
[0043] The smart glasses 1000 also includes a sensory stimulation component. This component, located on the frame A, sends sensory stimulation signals to the user, which stimulate the user to alter their brain function. The sensory stimulation component includes at least one of an augmented reality (AR) component, an extended reality (XR) component, a virtual reality (MR) component, an augmented virtual reality (VR) component, a mixed reality (AVR) component, and a speaker 810.

In this embodiment, the sensory stimulation component includes an AR component, an XR component, and a speaker 810.
[0044] A speaker 810 is disposed on the frame A. Specifically, the speaker 810 is disposed on the temple 200. The speaker 810 is disposed on the temple 200 and spaced apart from multiple EEG acquisition electrodes Q. In this embodiment, there are two speakers 810. The two speakers 810 are symmetrically disposed on the first temple 210 and the second temple 250. The speaker 810 can provide voice feedback to the user, play audio for the user, provide auditory stimulation signals to the user, change the user's brain function state, enhance the user's interactive experience with the smart glasses 1000, and improve the interactivity, audio experience, and multifunctionality of the smart glasses 1000, thereby enhancing the practicality and user experience of the smart glasses 1000. In some other embodiments, one or more speakers 810 may be provided; this application does not limit this.
[0045] The smart glasses 1000 also includes a microphone 850. The microphone 850 is located on the frame A. Specifically, the microphone 850 is located on the main body a of the temple 200. There are two microphones 850. The two microphones 850 are symmetrically arranged on the main body a of the first temple 210 and the main body a of the second temple 250. For example, one microphone 850 is located on the surface of the first temple 210 facing the second temple 250, and the other microphone 850 is located on the surface of the second temple 250 facing the first temple 210. The microphones 850 are configured to capture the user's voice commands and can be used for calls to enhance the user's interactive experience with the smart glasses 1000, thereby improving the interactivity of the smart glasses 1000. In some other embodiments, one or more microphones 850 may be provided; this application does not limit this.
[0046] The smart glasses 1000 also includes a main circuit board (not shown), a signal acquisition module (not shown), a signal transmission module (not shown), a processor (not shown), and a power supply (not shown). The main circuit board, signal acquisition module, signal transmission module, processor, and power supply are all located on the frame A. For example, the main circuit board, signal acquisition module, signal transmission module, processor, and power supply are all located on the main body a of the temple 200, and within the control area d.
[0047] In this embodiment, there are two main circuit boards to ensure the symmetrical structure of the smart glasses 1000. One main circuit board is located on the main body a of the first temple 210 and in the first control area d1. The other main circuit board is located on the second temple 250 and in the second control area d2. In some other embodiments, there may be one or more main circuit boards, and this application does not limit this.
[0048] The signal acquisition module, signal transmission module, and processor are all located on the main circuit board and are spaced apart. Specifically, the signal acquisition module, signal transmission module, and processor are all located on the main circuit board of each temple 200. The signal acquisition module is electrically connected to multiple EEG acquisition electrodes Q, used to control whether the multiple EEG acquisition electrodes Q acquire EEG signals, to acquire EEG signals from one or more EEG acquisition electrodes Q, and to perform preliminary processing on the EEG signals. It should be noted that the signal acquisition module can control one or more active electrodes 700 to acquire the user's EEG signals according to actual needs.
[0049] The signal transmission module is electrically connected to the signal acquisition module. The signal transmission module transmits the pre-processed EEG signals from the signal acquisition module to a remote server or processor. Both the remote server and processor are used for storing and analyzing the EEG signal data. The remote processor, such as in the cloud, can store and analyze large amounts of data collected over a long period, and perform statistical analysis calculations on this data. Its analysis reports are then fed back to external devices connected to the smart glasses 1000.
[0050] The processor is electrically connected to both the signal transmission module and the sensory stimulation component. The processor controls the sensory stimulation component to send sensory stimulation signals to the user based on the brainwave signals acquired by the multiple brainwave acquisition electrodes Q. The processor can perform embedded calculations and real-time analysis on the transmitted brainwave signals. Because the processor is located inside the smart glasses 1000, the brainwave signal data can be analyzed and statistically calculated within the smart glasses 1000, reducing the latency of data transmission and remote data analysis and calculation, thus ensuring data timeliness.
[0051] The power supply is spaced apart from the main circuit board and electrically connected to it, supplying power to the smart glasses 1000 and controlling the opening and closing of the main circuit board. There are two power supplies. One power supply is located on the first temple 210, in the first control area d1, and electrically connected to one main circuit board. The other power supply is located on the second temple 250, in the second control area d2, and electrically connected to another main circuit board. In some other embodiments, there may be only one power supply, and this power supply may be electrically connected to two main circuit boards; this application does not limit this.
[0052] The smart glasses 1000 also includes a first EEG acquisition system and a second EEG acquisition system. The first EEG acquisition system includes a main circuit board, EEG acquisition electrodes, and a power supply located on the first temple 210. The second EEG acquisition system includes a main circuit board, EEG acquisition electrodes, and a power supply located on the second temple 250. The first and second EEG acquisition systems can work independently or simultaneously.
[0053] It should be noted that in this embodiment, the smart glasses 1000 has a symmetrical structure, that is, the functions and internal components of the smart glasses 1000 are arranged symmetrically. Specifically, the active electrode 700, reference electrode 500, ground electrode 600, main circuit board, and power supply are all symmetrically arranged on the frame A. This allows the first and second EEG acquisition systems to work independently or synchronously. It also facilitates wiring and integrated circuits, balances the current distribution within the smart glasses 1000, improves the balanced reception and transmission of signals, and reduces signal noise and interference. This ensures that the EEG signals acquired by the multiple EEG acquisition electrodes Q in the two independent EEG acquisition systems are more stable and clearer. Furthermore, it improves wearing comfort and experience to meet the needs of daily long-term wear of the smart glasses 1000 for monitoring physical condition. In some other embodiments, there may be only one EEG acquisition system. In this case, the active electrode 700, reference electrode 500, ground electrode 600, main circuit board and power supply in the EEG acquisition system may not be designed symmetrically. There may be one or more active electrodes 700, and there may be only one reference electrode 500 and one ground electrode 600. This application does not limit this.
[0054] The smart glasses 1000 also includes a charging port 910 and an indicator light 950. Both the charging port 910 and the indicator light 950 are located on the main body a of the temple 200, and are spaced apart from the speaker 810 and microphone 850. There are two charging ports 910: one on the main body a of the first temple 210 and the other on the main body a of the second temple 250. The charging ports 910 allow connection to an external power source for charging the smart glasses 1000, and also provide data transmission functionality for data transfer. In some other embodiments, one or more charging ports 910 may be provided; this application does not limit this.
[0055] In this embodiment, there are two indicator lights 950. One indicator light 950 is located on the surface of the main body a of the first temple 210 opposite to the surface of the second temple 250, and the other indicator light 950 is located on the surface of the main body a of the second temple 250 opposite to the surface of the first temple 210. The indicator lights 950 can display the charging status of the smart glasses 1000. In some other embodiments, one or more indicator lights 950 may be provided, and this application does not limit this.
[0056] The smart glasses 1000 also includes a touch control e. The touch control e is located on the main body a of the temple 200 and is electrically connected to the processor. The touch control e is used to receive touch or swipe commands from the user and control the execution of functions of the smart glasses 1000. There are two touch controls e: one is located on the main body a of the first temple 210, and the other is located on the main body a of the second temple 250. By providing touch controls e, users can execute core, secondary, or auxiliary functions of the smart glasses 1000 via touch, improving the convenience and operational efficiency of the smart glasses 1000. In some other embodiments, the smart glasses 1000 may not have touch controls e, and users can wake up or switch functions of the smart glasses 1000 through a voice assistant.
[0057] In this embodiment, touch operations on the touch control e of the second temple 250 can execute the core functions of the smart glasses 1000. For example, a single click on the touch control e of the second temple 250 can control audio playback or pause of the smart glasses 1000; a swipe forward or backward on the touch control e can adjust the volume; and a double click on the touch control e can answer or hang up a phone call. In this embodiment, touch operations on the touch control e of the first temple 210 can execute secondary or auxiliary functions of the smart glasses 1000. For example, a single click on the touch control e of the first temple 210 can wake up the voice assistant or activate the AR function; a double click on the touch control e can switch audio modes or navigation modes; and a long press on the touch control e can quickly open applications or perform custom functions.
[0058] Please continue reading. Figure 1 and Figure 2 In this embodiment, the smart glasses 1000 further includes a first sensor (not shown). The first sensor is disposed on the frame A and electrically connected to the processor. For example, the first sensor may be disposed on the nose pad 300.

[0060] The smart glasses 1000 also includes a second sensor (not shown). The second sensor is located on the frame A and electrically connected to the processor of the smart glasses 1000. The second sensor can be located at at least one of the frame 100, temple 200, nose pad 300, and ear hook c. The second sensor is used to collect the user's physiological signals. The processor obtains the user's physiological information based on the monitoring results of the second sensor, thereby increasing the monitoring dimensions of the smart glasses 1000. The second sensor includes at least one of a photoplethysmogram (PPG), an accelerometer, and a gyroscope. For example, the PPG is located on the ear hook b. The smart glasses 1000 monitors heart health via the PPG. The accelerometer can be located on the main body a. The smart glasses 1000 monitors the user's step count via the accelerometer. The second sensor can be combined with a vital signs monitoring system to collect multimodal data, enabling comprehensive monitoring and assessment of the user and increasing the monitoring dimensions of the smart glasses 1000.
[0061] Please refer to the following: Figure 3 , Figure 3 yes Figure 1 The functional implementation logic of the smart glasses 1000 shown is illustrated.
[0062] In this embodiment, the smart glasses 1000 has a vital signs monitoring system. The vital signs monitoring system includes multiple EEG acquisition electrodes Q, a first sensor, a second sensor, a signal acquisition module, and a signal transmission module to monitor the user's vital signs. The multiple EEG acquisition electrodes Q include multiple reference electrodes 500, multiple ground electrodes 600, and multiple active electrodes 700. Because the smart glasses 1000 have a structure similar to ordinary glasses, they are portable and comfortable, allowing users to wear them daily for extended periods to monitor vital signs. The smart glasses 1000 can be used in scenarios such as work, study, or driving. The presence of multiple EEG acquisition electrodes Q allows for the collection of a large amount of EEG signals, enabling a comprehensive assessment of the user's state and improving the accuracy and comprehensiveness of the monitoring results. Specifically, when the user wears the smart glasses 1000, the smart glasses 1000 collects the user's EEG signals through the multiple EEG acquisition electrodes Q and processes them to reflect the brain function state. The processing methods include remote computing and embedded computing. Remote computing, achieved through remote servers such as cloud computing, can be used by the smart glasses 1000 to monitor users for extended periods without requiring immediate feedback. For example, the smart glasses 1000 can monitor a user's state for an hour, half a day, or a day or more; for instance, it can monitor a user's attention span. Specifically, the brainwave signals collected by the smart glasses 1000 are transmitted to the cloud for centralized storage and analysis, including long-term statistical calculations and trend analysis. After cloud computing is complete, the statistical results of the brainwave signals are returned to the user's terminal device and the external device connected to the smart glasses 1000, generating status reports, trend reports, and other analytical reports.
[0063] Embedded computing utilizes the processor of the smart glasses 1000 for computational analysis, enabling real-time monitoring of the user, such as emergency health status monitoring or real-time alerts. Specifically, the EEG signals collected by multiple EEG electrodes Q are directly processed and analyzed by the processor of the smart glasses 1000. This reduces data transmission and remote computation latency, ensures data immediacy, and provides rapid response, making it suitable for scenarios where the smart glasses 1000 performs real-time feedback training.
[0064] In this embodiment, the vital sign monitoring system and sensory stimulation component of the smart glasses 1000 constitute a closed-loop control mechanism. Specifically, taking the smart glasses 1000's focus monitoring and feedback training as an example, the closed-loop control mechanism is analyzed as follows: the EEG signals collected by multiple EEG acquisition electrodes Q of the smart glasses 1000 are directly monitored and analyzed in real time by the embedded computing system within the smart glasses 1000, and combined with the sensory stimulation component for immediate feedback training. Specifically, the feedback training provides sensory stimulation signals to the user through the sensory stimulation component of the smart glasses 1000. These sensory stimulation signals stimulate the user to change their brain function state. The multiple EEG acquisition electrodes Q then collect the user's EEG signals again and feed them back to the sensory stimulation component. The sensory stimulation component then sends sensory stimulation signals to further change the user's brain function state. Through this process, the smart glasses 1000 continuously monitors the user in real time through multiple EEG acquisition electrodes Q and repeatedly adjusts the user's brain function state through the sensory stimulation component to adjust the focus level in real time, thereby achieving adaptive focus improvement training. For example, the smart glasses 1000, combined with sensory stimulation components such as augmented reality (AR) and extended reality (XR) components, provides users with visual stimulation, thereby adjusting the user's attention to form feedback training. Alternatively, the smart glasses 1000, combined with sensory stimulation components such as a speaker 810, plays music to provide users with auditory stimulation, thereby adjusting the user's attention to form feedback training. It is important to note that the vital signs monitoring system in the smart glasses 1000, together with the sensory stimulation components, forms a closed-loop system, which not only improves the immediacy of data collection by the smart glasses 1000 but also provides users with a more interactive and engaging feedback training experience. The vital signs monitoring system of the smart glasses 1000 can also be used for monitoring and intervening in other brain functional states. For example, the smart glasses 1000 can be used for cognitive load monitoring, fatigue monitoring, emotion monitoring, and brain disease detection.

Figure 3The smart glasses 1000 can also monitor and collect blink signals in real time via active electrodes 700, thereby controlling the functions of the smart glasses 1000 and other external devices connected to the smart glasses 1000. For example, the smart glasses 1000 can control page turning in e-books or slideshows on external devices connected to the smart glasses 1000 using the collected blink signals. The smart glasses 1000 can also control music playback or pause, and start or stop attention monitoring and feedback training functions using the collected blink signals. The smart glasses 1000 can also interact with external devices via blink signals to control connected mobile phones or other smart devices, achieving convenient contactless operation. By collecting blink signals via active electrodes 700, the smart glasses 1000 enables interaction between users and external devices, not only improving the convenience of user operation but also providing a new human-computer interaction solution for special groups (such as people with mobility impairments), further expanding the application scenarios of the smart glasses 1000 in multiple fields. In some other embodiments, the smart glasses 1000 may also control the functions of the smart glasses 1000 and other external devices connected to the smart glasses 1000 by collecting other types of EEG signals, and this application does not limit this.
[0066] The smart glasses 1000 provided in this embodiment, through multiple EEG acquisition electrodes Q, achieves comprehensive monitoring, evaluation, and intervention of the user's brain function state. This improves the portability and comfort of EEG acquisition devices and enhances the accuracy and comprehensiveness of monitoring results. Specifically, the smart glasses 1000 can transmit the acquired EEG signal data to a remote server for analysis and processing, generating an analysis report for long-term monitoring of the user's vital signs. Alternatively, the smart glasses 1000 can perform embedded calculations on the acquired EEG signals within its internal processor and feed the analysis results back to the smart glasses 1000. Based on the analysis results, the smart glasses 1000 can then activate sensory stimulation components to regulate the user's brain function state, achieving closed-loop regulation and intervention. Furthermore, the smart glasses 1000 incorporates a second sensor that collects the user's physiological signals. This second sensor, combined with the EEG signal data collected by the multiple EEG acquisition electrodes Q, forms multimodal data, further increasing the monitoring dimensions of the smart glasses 1000 and enabling a comprehensive assessment of the user's brain function state.
