[0002] An important factor in the occurrence and development of myopia is long-term close-range eye use, which causes the ciliary muscle of the eye to be continuously tense, and then leads to the elongation of the eye axis. The technologies used in existing myopia control products include far-image light screen technology, simulated natural light technology, and electronic pulse acupoint technology, etc.

[0003] The far-image light screen technology can adjust the virtual viewing distance of the image, allowing users to see virtual long-distance images at close range, thereby relaxing the ciliary muscle and reducing the adjustment burden on the eyes.

Modern technology has realized the simulated application of electronic pulse acupoints through means such as microelectrical stimulation and vibration massage. Electronic pulse acupoint technology has been applied in eye massagers and health care devices, such as electronic eye health care instruments, eye massagers, etc. These devices usually stimulate the acupoints around the eyes through micro-vibration and electrical stimulation, which are convenient to use and have no side effects.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The myopia control effect of existing products needs to be further improved, and it is difficult to apply them jointly within the same time period, resulting in a relatively high time investment cost in use. In view of this, the present application combines multiple means. In an exemplary embodiment, such as Figure 1 and Figure 2As shown in the figure, a head-mounted integrated intelligent system for myopia prevention and control is provided, including: a head-mounted bracket 1, a far-image light screen imaging module, an analog natural light illumination module, an electronic pulse acupoint module 2, a sensing module, and a control module.

[0030] The far-image light screen imaging module, the analog natural light illumination module, the electronic pulse acupoint module 2, the sensing module, and the control module are all fixed on the head-mounted bracket 1. The head-mounted bracket 1 is used to be worn on the user's head and align the far-image light screen imaging module with the user's eyes when worn. The analog natural light illumination module and the electronic pulse acupoint module 2 are located at corresponding positions around the user's eyes.

[0031] The sensing module is used to detect the ambient light intensity, the user's eye position, the user's head posture, and the microelectrode position of the electronic pulse acupoint module 2 in real time. The control module is used to adjust the quality of the virtual image formed in the far-image light screen imaging module according to the ambient light intensity, the user's eye position, and the user's head posture detected in real time, so that the far-image light screen imaging module generates a clear virtual image; the far-image light screen imaging module is used to project the clear virtual image onto the user's eyes.

[0032] The control module is also used to control the analog natural light illumination module to project the simulated natural light onto the user's eyes.

[0109] ① Microprocessor

[0110] Function:

[0111] The microprocessor is the core of the entire control circuit board and is responsible for all calculation, control, and decision-making tasks. It processes sensor data, runs algorithms, and adjusts the image display effect and lens position as needed.

[0112] It includes receiving sensor data, executing control algorithms, and sending control signals to the display screen 3, the focusing device 5, and the image processor, etc.

[0113] The algorithm process inside the microprocessor includes the following key steps:

[0114] Data acquisition:

[0115] Receive sensor data from the sensor control chip. These data include eye position, head posture, ambient light changes, etc. The sensor control chip will transmit these data to the microprocessor regularly.

[0116] Data preprocessing:

[0117] The microprocessor performs simple preprocessing on the sensor data, such as denoising, filtering, and normalization, to ensure the accuracy and reliability of the data.

[0118] Status evaluation:

[0119] Evaluate the user's eye status based on the sensor data. For example, determine whether the eyes are fatigued, whether the head is turned, and whether the ambient light intensity has changed, etc. This information is crucial for adjusting the display effect.

[0120] Decision-making process:

[0121] If the head posture changes, the microprocessor will determine whether it is necessary to adjust the position of the optical lens group 4. For example, when the change amount of the head posture angle exceeds a certain threshold, the microprocessor will trigger an adjustment mechanism, calculate the displacement based on the attitude solution of the inertial measurement unit, generate an adjustment instruction according to the calculated displacement, and adjust the position of the optical lens group 4.

[0122] If the ambient light intensity changes, the microprocessor will adjust the display brightness. When the ambient light intensity is weak, increase the brightness; when the ambient light intensity is strong, reduce the brightness. Through techniques such as histogram equalization, enhance the contrast of the image to make the image details clearer.

[0123] Instruction generation and execution:

[0124] The microprocessor generates a control signal according to the decision result, and commands the interface module to transmit the signal to the image processor, the focusing device 5, and other related components to complete the adjustment.

[0125] Such as: adjusting the focal length of the optical lens, optimizing the brightness and contrast of the display screen 3, etc.

[0126] Feedback and adjustment:

[0127] The microprocessor receives the feedback data from the sensor system in real time to ensure that the adjustment effect meets the user's needs. If the adjusted effect is not ideal, the microprocessor will execute the above process again to further optimize the control parameters.

[0128] ② Interface module

[0129] Function:

[0130] The interface module is a bridge between the microprocessor and other components (such as the image processor, the focusing device 5, the sensor system, etc.). It is responsible for converting the output signal of the microprocessor into a format suitable for each module to receive, ensuring the stability and efficiency of data transmission.

[0131] For example, the interface module performs data conversion (such as converting from a digital signal to an analog signal) and signal enhancement (such as removing noise) to ensure the correct transmission of the signal between different components.

[0132] ③Sensor control chip

[0133] Function:

[0134] The sensor control chip is responsible for managing and controlling the operation of the sensor system (such as infrared sensors, light sensors, and gyroscopes, etc.). It reads the data from each sensor and transfers this data to the microprocessor.

[0135] Control the sampling frequency and data accuracy of the sensors, and perform necessary preprocessing (such as filtering, amplification, etc.) to ensure that the microprocessor can receive valid sensor information.

[0136] The detailed process of the algorithm inside the sensor control chip is as follows:

[0137] Sensor data acquisition:

[0138] The sensor control chip collects data from sensors (such as infrared sensors, light sensors, and gyroscopes).

[0139] The infrared sensor is mainly used to detect the eye position, the light sensor is used to monitor the ambient light intensity, and the gyroscope is used to detect the head posture and movement direction.

[0140] Data preprocessing and filtering:

[0141] Perform preprocessing on the collected data, such as denoising and filtering, to ensure the accuracy of the data.

[0142] Data integration and synchronization:

[0143] Integrate and synchronize the data from different sensors. The sensor control chip needs to ensure that these data are aligned in time so that the microprocessor can efficiently use this information for decision-making.

[0144] Data transmission:

[0145] Transmit the processed data to the microprocessor through the interface module. This process needs to ensure the reliable transmission of the data, and usually uses digital signal processing (DSP) technology to improve the accuracy and speed of data transmission.

[0146] Real-time monitoring and feedback:

[0147] The sensor control chip continuously monitors the working status of the sensors. If a sensor fails or has a deviation, the sensor control chip needs to detect it in real time and send an alarm signal to ensure the stable operation of the system.

[0148] 2. The second control circuit board

[0149] Function: Receive the instructions of the control system, control the operation of the electric drive system, and process the data from the position sensor.

[0150] Composition: a second microprocessor, a signal amplifier, and a second interface module.

[0151] Positional relationship: The second control circuit board is installed inside the electronic pulse acupoint module 2 and is connected to the electric drive system and the position sensor through a cable.

[0152] The position sensor is connected to the signal amplifier through the second interface module; the second microprocessor is respectively connected to the signal amplifier and the electric drive system. The signal amplifier is used to amplify the signals of the user's eye position and microelectrode position detected by the position sensor in real time and then transmit them to the second microprocessor. The second microprocessor is used to compare the amplified user's eye position and microelectrode position. If the deviation between the microelectrode position and the user's eye position is less than the preset threshold, it controls the electric drive system to adjust the microelectrode stimulation position; if the deviation between the microelectrode stimulation position and the user's eye position is greater than or equal to the preset threshold, it controls the electric drive system to stop and issue an alarm or error prompt.

[0153] The specific processing process and processing results of the second microprocessor are as follows:

[0154] Data acquisition:

[0155] Each position sensor (optical) continuously acquires data and transmits these data to the control circuit board through the interface module.

[0156] The data includes the current position of the microelectrode, the specific position of the user's eye, and their relative positional relationship.

[0157] Data preprocessing:

[0158] The signal amplifier amplifies and filters the sensor signals to eliminate noise and interference.

[0159] The microprocessor receives the preprocessed data and converts it into a digital signal for further processing.

[0160] Data analysis and position calculation:

[0161] The microprocessor runs a positioning algorithm to calculate the three-dimensional space coordinates of the microelectrode and the user's eye.

[0162] Establish a real-time coordinate system to determine the distance and angular relationship between the microelectrode and the target acupoint.

[0163] Decision-making and control signal generation:

[0164] According to the predetermined electronic pulse path and position accuracy requirements, the microprocessor compares the current microelectrode position with the target position and calculates the required adjustment amount.

[0165] Generate different control signals according to specific situations, including commands for the movement in and out of the microelectrodes, commands for force adjustment, etc.

[0166] Feedback and safety monitoring:

[0167] Monitor the system status in real time, especially the changes in the position of the microelectrodes and the position of the user's eyes.

[0168] If an abnormal situation is detected (such as the microelectrode deviating from the predetermined trajectory or the sudden change in the position of the user's eyes), the microprocessor immediately generates an alarm signal or a shutdown command.

[0169] The position of the microelectrode deviates from the target position:

[0170] Processing result: There is a deviation between the current position of the microelectrode and the target acupoint position.

[0171] Control measures: Adjust the electric drive system, control the movement of the micro-motor and the drive rod, and make the microelectrode return to the correct trajectory. The specific operations include the extension and retraction of the drive rod and the rotation of the gear system.

[0172] The microelectrode reaches the target position:

[0173] Processing result: The microelectrode has reached the target acupoint position.

[0187] Connection relationship: Connected to the head-mounted bracket 1 module, the sensor is connected to the control module through a data cable or wirelessly, and transmits the detected data to the control module.

[0188] 1. Position sensor

[0189] Function: Used to detect the position of the electronic pulse device and the specific position of the user's eyes in real time to ensure the accuracy of the electronic pulse.

[0190] Composition: An optical sensor or an ultrasonic sensor.

[0191] Position relationship: The position sensor is installed around the microelectrode fixing base and can cover the entire electronic pulse range.

[0192] The detection principle of the optical sensor is that the optical sensor detects the position of an object through the reflection, refraction or occlusion of light. The specific process is as follows:

[0193] Arrangement of the optical sensor:

[0194] The optical sensor is installed around the microelectrode fixing base to form a detection network covering the entire electronic pulse range.

[0195] The sensor emits a light beam (such as a laser, infrared light, etc.) and receives the reflected light or judges the position of an object through the occlusion of light.

[0196] Eye position detection:

[0197] The optical sensor emits a light beam, the light beam irradiates the user's eyes and reflects back, and calculates the position of the user's eyes by receiving the time difference, intensity or angle change of the reflected light.

[0198] The sensor may perform multi-point scanning to form a three-dimensional model to accurately locate each area of the user's eyes.

[0199] Microelectrode position detection:

[0200] Similarly, the optical sensor can determine the three-dimensional spatial position of the microelectrode by detecting the reflected light at the position of the microelectrode.

[0201] The sensor monitors the movement trajectory of the microelectrode in real time to ensure that the distance and angle between its position and specific acupoints on the eye meet the predetermined stimulation requirements.

[0202] Data processing and feedback:

[0203] The collected position data is transmitted to the control circuit board through signal transmission.

[0204] The microprocessor processes this data, generates real-time position information, and adjusts the movement trajectory and stimulation intensity of the microelectrode.

[0205] 2. Sensor system

[0211] Functions of the interaction interface: Provide an interaction interface between the user and the device, including input of control parameters and real-time feedback of the status of each module. Connection relationship: Connect to the control module through a data cable or wirelessly. The user inputs instructions through the interface, and the control module makes corresponding adjustments according to the instructions.

[0212] In summary, the key technologies of the present application are:

[0213] 1. Design and implementation of the far-image light screen imaging module: including the optical lens group 4, the image processor, and how to realize the adjustment of the image's far and near viewing angles.

[0214] 2. Design and Implementation of the Simulated Natural Light Module: It includes the light source, light intensity, and color temperature adjustment mechanisms, and how to effectively simulate the natural light environment.

[0215] The specific contents of the light source, light intensity, and color temperature adjustment mechanisms include:

[0216] Light Source Type and Selection:

[0217] The light source is an OLED light source, which can provide high-brightness, good uniformity, and adjustable color temperature lighting effects.

[0218] Light Intensity Adjustment Mechanism:

[0219] The light intensity adjustment is based on sensor data, especially the ambient light sensor. The ambient light sensor can measure the light intensity of the surrounding environment in real time.

[0220] The microprocessor adjusts the brightness of the light source according to the external light intensity and the user's eye perception (such as eye fatigue, light sensitivity, etc.). If the detected ambient light is dim, the system will automatically increase the light intensity; if the ambient light is strong, the light source brightness will be automatically reduced to avoid glare.

[0221] Comprehensive Adjustment:

[0222] The microprocessor integrates control algorithms to fuse the real-time data of light intensity, color temperature, and ambient light intensity, and dynamically adjusts the parameters of the light source to ensure that users can obtain a comfortable visual experience in any environment.

[0223] 3. Design and Implementation of the Electronic Pulse Acupoint Module 2: It includes the specific structure of the electronic pulse device, the stimulation method, and its precise positioning of the acupoints around the eyes.

[0224] Precise Positioning:

[0225] The sensor system (such as vision sensors, infrared sensors, head posture sensors, etc.) is used to monitor the head and eye positions of the user in real time to ensure the precise positioning of the electronic pulse device.

[0226] Stimulation Mechanism:

[0227] The method uses microelectrodes to stimulate specific acupoints around the eyes (such as Jingming, Taiyang, Cuanzhu, etc.) by precisely controlling the stimulation intensity, frequency, and time interval.

[0228] The stimulation parameters can be dynamically adjusted according to user needs, environmental factors, and sensor feedback. For example, after long-term screen viewing, the system may automatically activate the stimulation of acupoints around the eyes to relieve eye fatigue.

[0229] Stimulation Control:

[0230] The microprocessor automatically adjusts the stimulation intensity and duration of the electronic pulse device according to the user's physiological responses and needs. The sensor monitors the responses in the stimulation area (such as muscle relaxation) in real time and adjusts the stimulation strategy in a timely manner to provide a comfortable and effective treatment effect.

[0231] 4. Design and implementation of the head-mounted bracket 1: including the material of the bracket, wearing comfort, stability, and its connection method with other modules.

[0232] 5. Design and implementation of the integrated control module: including the sensor system, control algorithm, and its comprehensive adjustment method for optical imaging, illumination, and electronic pulse intensity.

[0233] Among them, the control algorithm of the control module generally includes the following processes:

[0234] Data acquisition: The sensor system monitors data such as the user's eye position, ambient light, and eye fatigue level in real time.

[0235] Data analysis and processing: The control algorithm analyzes the acquired data to identify the current eye state of the user. For example, it judges whether the user's eyes are overly fatigued or the eye's adjustment ability to the far image screen.

[0236] Decision-making process: Based on the analysis results, the algorithm decides the parameters that need to be adjusted. For example, if the user is in a relatively dark environment, the brightness of the illumination module may need to be increased; if there are signs of eye fatigue, the electronic pulse intensity may need to be increased.

[0237] Instruction generation: The control algorithm generates specific control instructions to direct the far image screen, illumination, electronic pulse module, etc. to make corresponding adjustments.

[0238] Feedback adjustment: The sensor feeds back the adjusted data, and the control system continues to adjust the parameters based on the new data to ensure continuous optimization of the effect.

[0239] Among them, the specific process of the comprehensive adjustment method for optical imaging, illumination, and electronic pulse intensity is:

[0240] Optical imaging adjustment:

[0241] The control system adjusts the imaging effect of the far image screen according to the eye position and fatigue level. If the eyes are overly fatigued, the system will automatically increase the clarity and contrast of the far image, simulate a more natural farsighted environment, and reduce the eye adjustment burden.

[0242] Illumination adjustment:

[0243] The system automatically adjusts the light intensity according to the ambient light intensity detected by the ambient light sensor. If the light is insufficient, the system will increase the brightness of the simulated natural light or adjust the color temperature so that the eyes are in a more comfortable lighting environment.

[0244] Electronic pulse intensity adjustment:

[0245] The control system adjusts the electronic pulse intensity according to information such as the eye fatigue level and usage time. A higher fatigue level may mean that a stronger stimulation intensity is needed to promote blood circulation; while a lower fatigue level may be suitable for a mild stimulation intensity.

[0246] In addition, the timing and frequency of the electronic pulse module are also adjusted according to the feedback of the algorithm to ensure the effectiveness and comfort of the stimulation.

[0247] Among them, the specific process of realizing the adjustment of the image's far and near perspectives is as follows:

[0248] Sensor data acquisition:

[0249] Use a head pose sensor (such as a gyroscope) and an eye movement sensor (such as an infrared sensor) to obtain the user's eye position and head movement in real time. These data provide a basis for judging the user's visual needs.

[0250] Data processing and analysis:

[0251] The microprocessor receives and processes the data from the sensors to determine the user's head pose and the focal length requirement of the eyes.

[0252] According to the relative distance and viewing angle between the user's eyes and the display screen 3, the microprocessor runs an algorithm to adjust the position or focal length of the optical lens group 4. If the user needs to view a distant object, the system will adjust the focal length of the lens group to simulate a far perspective; if the user approaches the display screen 3, the focal length of the lens group will be adjusted to a near perspective.

[0253] The focusing device 5 (such as an electric focusing motor) operates according to the instructions of the microprocessor to adjust the position or focal length of the lens group in real time to ensure that the image is always clear.

[0254] Feedback and fine-tuning:

[0255] The system continuously monitors the user's head and eye positions and adjusts the focal length of the image in real time according to the changes to ensure visual comfort. For example, when it detects that the user is gazing at a distant object, the system will automatically adjust the image to the optimal far-sighted state.

[0256] The advantages of this application are as follows:

[0257] Effectively relieve visual fatigue: Through the far-image light screen imaging and simulated natural light technology, reduce the eye adjustment burden and light fatigue.

[0258] Prevention and control of myopia development: Comprehensively apply a variety of technical means to provide comprehensive vision protection.

[0259] Provide a comfortable wearing experience: The design of the head-mounted bracket 1 improves the comfort and stability of wearing.
