Visual training is a series of targeted exercises and activities that help improve visual function, solve vision problems or relieve visual fatigue. Eye muscle training can enhance the coordination and strength of eye muscles to improve eye movement and stability. Visual attention training can improve the ability to concentrate and the speed of visual information processing to cope with complex visual tasks.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combine the following Figure 1-Figure 5 The vision training method, device and vision training device of the present invention are described.

[0024] The vision training method of the embodiment of the present invention is applied to a vision training device. The vision training device of the embodiment of the present invention is first described below.

[0025] like Figure 1 As shown, the vision trainer of the embodiment of the present invention includes a handheld bracket 110 and a sight mark 120 installed on the handheld bracket 110, a detachable training lens 130, a first sensor 140, a second sensor 150, a sound emitting device 160 and a sound receiving device 170, the first sensor 140 is used to detect the relative position of the user's pupil and the training lens 130, and the second sensor 150 is used to detect the user's facial features and the distance from the training lens 130.

[0026] The handheld bracket is used to support and fix other components, allowing the user to conveniently hold and operate the vision trainer.

[0027] Optotypes are visual target patterns or display areas mounted on a handheld stand that users need to look at and follow for training. These optotypes can include different shapes, colors, or movement patterns for a variety of vision training tasks.

[0028] The detachable training lenses can be replaced or adjusted as needed to change the difficulty of training or provide different visual effects. The detachable design allows the device to be flexibly adjusted at different training stages.

[0029] The first sensor is used to detect the relative position between the user's pupil and the training lens. This helps ensure that the training lens is at the appropriate distance from the user's eyes to achieve accurate training results.

[0030] The second sensor is used to detect the user's facial features and the distance from the training lenses. This helps the device understand the user's facial position and the distance from the lenses to adjust the training content and method to achieve accurate training results.

[0031] The sound device is used to issue sound prompts or guidance to help the user follow the correct steps for training. For example, it can prompt the user when to adjust the viewing angle or change the training mode.

[0032] The sound receiving device is used to receive the user's voice feedback or instructions, which can help the device adjust the training settings or interact according to the user's feedback.

[0033] The design of the vision trainer combines multiple sensors and auxiliary devices to provide accurate vision training. The cooperation of the first sensor and the second sensor ensures that the relative position between the user's eyes and the device is correct, thereby improving the effectiveness of the training.

[0034] By detecting pupil position and facial features, the device can automatically or intelligently adjust the settings of the training lenses to optimize the training conditions and adapt to the user's actual situation.

[0035] The sound-generating device and the sound-collecting device make the training process more interactive and dynamic. Users can get real-time feedback and adjust the training method as needed, thereby reducing the difficulty of the training process and increasing the fun of the training.

[0036] The handheld bracket can also be used to carry various sensors and different lenses. The handheld bracket can also be integrated with electronic integration modules, network modules, power modules, etc.

[0037] like Figure 2 As shown, the visual training method in the embodiment of the present invention mainly includes step 210, step 220, step 230, step 240 and step 250.

[0038] Step 210: Detect the relative position of the user's pupil with respect to the training lens by using a first sensor.

[0039] The first sensor may be an image sensor, a photoelectric sensor or an eye tracker, etc. The first sensor is used to detect the position of the user's pupil from the first sensor, and obtain the relative position of the user's pupil relative to the training lens based on the training lens and the relative position of the training lens.

[0040] When using image sensors, high-resolution image sensors can be used in conjunction with image processing algorithms to identify and track the position of the pupil. The camera captures the user's eye image, and uses image processing algorithms (such as edge detection, feature point detection, etc.) to identify the position of the pupil and calculate the distance and angle of the pupil relative to the training lens.

[0041] When using an eye tracker, the eye tracker determines the position of the pupil by recording the movement of the eye, and infers its relative position relative to the training lens by calculating the position and angle of the eye. An eye tracker is a device used to measure and record eye movements. It tracks the movement trajectory of the eyeball and detects the eye's gaze point, blinking frequency, eye rotation angle, etc. An eye tracker usually contains high-precision sensors and cameras, which capture subtle changes in the eye through infrared light or other optical technology.

[0042] In the case where the first sensor is an eye tracker, after the user is reminded by a sound device to rotate the vision trainer based on the deflection angle so that the user's pupil is aligned with the angle of the training lens to start training, the vision training method of an embodiment of the present invention also includes: during the user's training process, detecting the user's eye movement data by the eye tracker; and correcting the user's eye movement during the training process by the sound device based on the eye movement data.

[0043] During this process, the user can hold the handheld stand so that the sight mark is on the left side, and use the eye tracker to monitor the user's eye movement, which can detect whether the user's pupil is aligned with the training lens, or whether the user's pupil is looking in the direction of the sight mark. When the user starts training, the eye movement data can be continuously tracked and recorded, and real-time feedback can be provided through the sound device.

[0044] If it is detected that the user's eye movement deviates from the preset track or target, the sound device will issue a sound prompt to correct the user's eye movement behavior. In this way, the user can continuously adjust his or her eye position during the training process, thereby improving the training effect and ultimately improving visual ability. In addition, real-time monitoring and feedback during the training process enhance the interactivity and effectiveness of the training.

[0045] Step 220 , based on the relative position of the user's pupil relative to the training lens, determine the deviation information of the user's pupil relative to the center of the training lens.

[0046] By detecting the actual position of the user's pupil relative to the training lens, the device can calculate the degree of deviation of the pupil from the center of the lens. This deviation information can help the device understand whether the pupil is aligned with the ideal position of the training lens, so as to make corresponding adjustments to ensure the accuracy and effectiveness of vision training. In short, it is used to measure and correct the deviation of the pupil on the lens.

[0047] Step 230: Based on the deviation information, the user is reminded through a sound device to move the vision training device so that the user's pupil is aligned with the training lens position.

[0048] When the user's pupil is aligned with the training lens, the projection of the user's pupil on the plane corresponding to the training lens is within the range of the training lens.

[0049] Deviation information refers to the offset of the user's pupil position relative to the center of the training lens. The training lens usually has an optimal observation position. Under optimal conditions, the user's pupil should be aligned with the center of the training lens. When the user's pupil deviates far from this center, this offset can be detected and deviation information can be generated.

[0050] Feedback can be provided through a sound device. If the user's pupil deviates from the ideal position of the training lens, the user can be reminded to make adjustments through a prompt sound or voice. This feedback mechanism can help the user correct the posture of the trainer or head in time to avoid affecting the training effect.

[0051] The pupil is aligned with the position of the training lens, which means that the user's eyes should be observed just through the range of the training lens. Specifically, when the pupil of the user's eye passes through the training lens, its projection should be within the range of the lens.

[0052] The training lens can usually be regarded as a plane. When the user's pupil passes through the lens, there will be a projection on the lens (that is, the user's eye's perspective projection on the lens plane). If the user's eye position is incorrect, the pupil projection may deviate from the effective range of the lens. When the pupil projection falls within the range of the training lens, it means that the user's eye position is aligned with the lens.

[0053] When the user's pupil is correctly aligned with the training lens, it can be detected that the projection of the pupil on the lens plane is within the range of the lens. The user's line of sight just passes through the training lens and is in a relatively ideal training position. If it is detected that the projection of the pupil deviates from the area of ​​the training lens, the sound device can be used to remind the user to adjust the line of sight or the position of the trainer to ensure that the pupil returns to the correct position.

[0054] Step 240: When the user's pupil is aligned with the training lens, the second sensor is used to detect the user's facial features and determine the deflection angle of the vision trainer relative to the user's face.

[0055] In the previous stage, the user's pupil has been adjusted to the range of the training lens according to the aforementioned process (detected by the first sensor and based on the prompt of the sound-emitting device).

[0056] After the pupils are aligned, the user's facial features can be further detected by a second sensor, such as a depth camera or a facial recognition sensor. These features usually include landmark facial points such as eyes, nose, and mouth, which are used to analyze the user's facial posture. The positional relationship of these points can be detected to determine the posture of the user's face relative to the visual trainer.

[0057] The deflection angle refers to the relative rotation angle between the visual trainer and the user's face. Assuming that the user's face is a plane and the visual trainer is a movable device, it is necessary to ensure that the angle between the two planes is ideal, usually parallel or at a certain angle.

[0058] If there is a deviation between the vision trainer and the user's face, such as the device is tilted or turned, this deviation angle can be detected.

[0059] Even if the user's pupil position is aligned with the training lens position, if the overall angle of the visual trainer and the face is not aligned, the training effect will be affected. For example, if the trainer is tilted horizontally or vertically, the user's pupil may be in an unnatural position, affecting the relationship between the line of sight and the sight mark. Therefore, it is necessary to further determine whether the trainer maintains the correct angle relationship with the face by detecting facial features.

[0060] When the user's pupil is aligned with the training lens, the second sensor will detect the user's facial features, analyze the facial posture and angle, and determine whether there is a deflection between the visual trainer and the user's face. Based on this deflection angle, the user can be reminded to adjust the posture of the trainer to ensure that the angle between the visual trainer and the user's face remains appropriate, making the training conditions more ideal, further improving the accuracy and effect of the training, and ensuring that the relationship between the user's line of sight and the training lens and the trainer is in the best state.

[0061] Step 250, based on the deflection angle, the user is reminded through the sound device to rotate the vision trainer so that the user's pupil is aligned with the training lens angle to start training; when the user's pupil is aligned with the training lens angle, the plane where the user's pupil is located is parallel to the plane corresponding to the training lens.

[0062] In the previous step, the second sensor has detected the deflection angle between the user's facial posture and the trainer. This deflection angle indicates whether there is an angular error between the visual trainer and the user's face, that is, whether the visual trainer is tilted, rotated or deflected. In order to keep the trainer and the user's line of sight in an ideal training posture, it is necessary to first determine this deflection angle.

[0063] Once the deflection angle is determined, the user can be reminded through a sound device. If the angle is incorrect, the user can be informed that the visual trainer needs to be turned or adjusted. For example, if the visual trainer is tilted or rotated, the user needs to turn the visual trainer according to the prompt to correct the angle between the visual trainer and the face, ensuring that the user's line of sight and the visual trainer can be maintained at the correct angle for effective training.

[0064] When the user adjusts the trainer according to the voice prompts so that the angle of his pupil is aligned with the angle of the training lens, the angle of the user's pupil projected on the lens has completely matched the angle of the training lens. Angle alignment means that the direction of the user's eyes and the training lens is correct, without any tilt or deflection error.

[0065] When it is detected that the user's pupil is aligned with the angle of the training lens, the plane where the user's pupil is located is parallel to the plane corresponding to the training lens. In other words, the user's line of sight is facing the training lens, and there is no line of sight angle deviation.

[0066] When the plane of the user's pupil is parallel to the plane of the training lens, the training condition reaches the ideal state. Parallel means that the user's line of sight is aligned with the training lens in the most direct and effective way. If there is an angle deviation, the training effect may be disturbed or inaccurate.

[0067] When the user's pupil is aligned with the angle of the training lens, it means that the user's line of sight is consistent with the direction of the training lens, and the plane where the user's pupil is located is parallel to the plane of the training lens. During the alignment process, the user can be reminded by the sound device to adjust the device angle or their posture until the angle of the pupil and the lens are completely aligned. In this parallel state, the alignment of the user's line of sight with the trainer is optimal, and training can begin in an ideal posture, thereby ensuring the accuracy and effectiveness of vision training.

[0068] According to the vision training method provided by the embodiment of the present invention, the relative position of the user's pupil and the training lens is detected by the first sensor, and whether the pupil is aligned with the lens can be monitored in real time. An accurate prompt is given by the sound device to remind the user to adjust the position of the vision trainer in time, ensuring that the position of the user's eyes is always within the effective training range of the training lens during the training process. After the pupil is aligned with the training lens, the second sensor detects the user's facial features to determine the deflection angle of the vision trainer. When an angle deviation is detected, the user is prompted to turn the trainer by sound to ensure that the user's line of sight remains parallel to the lens, thereby further improving the accuracy of the training and avoiding the interference of the angle deviation on the training effect. The user does not need to rely on manual or visual judgment, which reduces the difficulty of complex operations and alignment processes and improves the overall user experience. The user does not need to have professional technical knowledge to complete the training preparation work, so that the training posture meets the requirements, ensures the standardization and consistency of the training, and avoids fluctuations in training quality caused by alignment or angle deviation.

[0069] In some embodiments, detecting facial features of the user by a second sensor and determining a deflection angle of the vision trainer relative to the user's face includes the following process.

[0070] The second sensor can detect the user's facial features, identify the user's eyes and nose, and obtain the relative position of the user's eyes and nose; then, based on the relative position of the user's eyes and nose, create facial feature points to define the equation of the facial plane, and obtain the position of the plane where the user's face is located; finally, based on the position of the plane where the user's face is located, determine the deflection angle of the visual trainer relative to the user's face.

[0071] In this embodiment, the facial features of the user can be detected by the second sensor, and the relative position between the eyes and the nose can be identified to determine the deflection angle of the vision trainer relative to the user's face.

[0072] The second sensor can be a camera or a depth sensor. First, the key feature points of the user's face are detected, usually including the eyes and nose. These two feature points are fixed positions on the face, and their relative relationship can stably reflect the orientation and angle of the user's face.

[0073] The overall posture of the user's face can be determined based on the relative position between the eyes and the nose. For example, the positional relationship between the eyes and the nose relative to the vision trainer can provide angular information about whether the user's head is tilted, raised, or bent.

[0074] On this basis, an equation for a "face plane" can be created through geometric methods based on the relative positions of the user's eyes and nose. This is to construct a two-dimensional or three-dimensional geometric model based on the relative positions of the eyes and nose to define the orientation and plane of the face.

[0075] By calculating the angle between the equation of the user's facial plane and the plane of the visual trainer, the deflection angle of the visual trainer relative to the user's face can be accurately identified. The deflection angle may include left and right tilt (horizontal angle) and up and down tilt (vertical angle), thereby giving feedback to the user whether the trainer needs to be adjusted.

[0076] In this embodiment, by automatically detecting facial features, the user does not need to make manual adjustments or rely on external devices to help with alignment. It can automatically identify whether there is a deflection angle and accurately give adjustment prompts, which greatly improves the ease of use of the trainer and the accuracy of alignment, ensuring that visual training is always carried out in the best condition.

[0077] Everyone has different facial features, and judging the facial plane by the relative position of the eyes and nose can adapt to the facial shapes and sizes of different users, making the visual trainer widely applicable to a variety of people without the need for complex adjustments for each user.

[0078] During the training process, it can give real-time prompts to adjust the trainer according to changes in facial features. When the user changes the head posture or position during training, it can automatically identify deviations through continuous detection and promptly remind the user to make adjustments, thus ensuring the consistency and effectiveness of the training effect.

[0079] Users do not need to make frequent and tedious manual adjustments, they only need to make fine adjustments according to the prompts issued by the system. This automated detection and feedback mechanism reduces the complexity of manual adjustments during training and increases the comfort and naturalness of the training process.

[0080] In some embodiments, Figure 3 As shown, after the user is reminded by the sound device to rotate the vision trainer based on the deflection angle so that the user's pupil is aligned with the training lens angle to start training, the method further includes steps 310, 320, 330, 340 and 350.

[0081] Step 310: Receive the user's voice input through a sound receiving device.

[0082] Step 320, determining the training mode and user information based on the user's voice input.

[0083] Step 330: Determine the target distance between the pupil and the sight mark of the user during training based on the training mode and user information.

[0084] Step 340: Detect the actual distance between the pupil and the sight mark on the user's face by using a second sensor.

[0085] Step 350: When the actual distance does not match the target distance, the user is reminded to adjust the actual distance to the sight mark through the sound device.

[0086] It is understandable that the user's voice input is received through a sound receiving device such as a microphone. The user can interact with the visual trainer through voice, for example, telling the visual trainer which mode of training they are ready to start, or providing other relevant user information. Voice interaction simplifies the way users interact with the device, especially for users who do not want to rely on manual operation, such as children.

[0087] When determining the training mode and user information based on the user's voice input, the training mode required by the user and the user's personal information can be identified by processing the user's voice input. The training mode may involve different training intensities, methods or goals, such as hyperopia correction, myopia correction, etc. User information may include the user's age, vision status, etc. Automatically determining this information through voice input improves the personalization and convenience of the training process, without the need for manual settings by the user, and increases the comfort and intelligence level of the user experience.

[0088] Based on the training mode selected by the user and the user information recognized by the system, the optimal target distance of the user's pupil from the sight mark during training can be automatically calculated. This distance is set based on scientific training parameters and individual differences of users (such as vision status). For example, for training to correct myopia, the system may require the user's pupil to be 20 cm away from the sight mark, while different distances may be set for other training. By determining this target distance, it is ensured that the user is in the correct distance range during training to maximize the training effect.

[0089] The second sensor continuously monitors the user's face, especially the actual distance between the user's pupil and the sight mark. This step is performed in real time during the training process to ensure that the user's position always remains within the target distance. By detecting the actual distance in real time, dynamic feedback can be provided on whether the user is in the correct position, ensuring the accuracy and effectiveness of the training.

[0090] In the event that the actual distance does not match the target distance, the user can be reminded to adjust the actual distance to the sight mark through the sound device. If the second sensor detects that the actual distance between the user's pupil and the sight mark does not match the preset target distance (too far or too close), the user can be reminded to make adjustments through the sound device. For example, if the user accidentally steps back or gets too close during training, the vision trainer will sound a reminder to remind them to adjust to the correct position. Through this automatic reminder, users can get instant feedback during training, reduce human errors, and ensure that the entire training process remains within the correct parameters.

[0091] In some embodiments, Figure 1 As shown, the training lens is mounted on the handheld bracket via an electronic slide rail 111. The electronic slide rail can slide up and down on the handheld bracket 110.

[0092] After determining the deviation information of the user's pupil relative to the center of the training lens based on the relative position of the user's pupil relative to the training lens, the vision training method of the embodiment of the present invention further includes: detecting the user's pupil distance by means of the second sensor; and based on the deviation information and the user's pupil distance, controlling the electronic slide rail to move the training lens along the axial direction of the handheld bracket so that the pupils of both eyes of the user are respectively aligned with the left and right lens positions of the training lens.

[0093] In this process, the first sensor first obtains the deviation information of the user's pupil relative to the training lens to understand whether the user's eyes are accurately aligned with the training lens. Next, the second sensor is used to measure the user's pupil distance. According to the deviation information and pupil distance, the electronic slide rail can be controlled to move the training lens along the axis of the handheld bracket, thereby adjusting the position of the left and right lenses so that the user's pupils are accurately aligned with their respective training lenses. This automatic adjustment mechanism ensures the accuracy of training and helps users achieve better visual training results.

[0094] After determining the deviation information of the user's pupil relative to the center of the training lens based on the relative position of the user's pupil relative to the training lens, the vision training method of the embodiment of the present invention also includes: determining that the deviation information of the user's pupil relative to the center of the training lens is that the distance that the user's pupil deviates in the axial direction of the handheld bracket is smaller than the adjustable distance of the electronic slide rail for the training lens in the axial deviation direction of the handheld bracket; and controlling the electronic slide rail to move the training lens along the axial direction of the handheld bracket so that the user's pupil is aligned with the position of the training lens.

[0095] The training lens is mounted on an electronic slide that is fixed to the handheld holder. The electronic slide allows the training lens to be adjusted along the axial direction of the holder (usually up and down) while the user holds the vision trainer by the handheld holder.

[0096] In this embodiment, through the adjustable electronic slide rail, the vision trainer can automatically and accurately adjust the position of the training lens according to the actual situation of the user to ensure that the training lens is aligned with the user's pupil, thereby improving the accuracy and convenience of the training effect.

[0097] If the detected deviation distance between the pupil and the center of the training lens is smaller than the distance range that the electronic slide rail can adjust, that is, the electronic slide rail has enough moving space to compensate for the deviation, the slide rail can be controlled to move the training lens for automatic alignment.

[0098] After confirming that the deviation distance is within the adjustment range of the slide rail, the electronic slide rail can be controlled to move the training lens along the axial direction of the bracket until the pupil is aligned with the training lens position. In other words, the electronic slide rail will automatically adjust the position of the training lens instead of requiring the user to manually adjust the position of the vision trainer.

[0099] In this embodiment, through the automatic adjustment of the slide rail, the user can complete the alignment of the training lens and the pupil without manually moving the vision trainer, which not only improves the convenience of operation, but also enhances the accuracy of alignment and reduces human errors. If the user moves slightly during use, the vision trainer can make real-time adjustments to adapt to individual differences, especially for children or elderly users.

[0100] In some embodiments, after the user is reminded by a sound device to rotate the vision trainer based on the deflection angle so that the user's pupil is aligned with the training lens angle to start training, the vision training method further includes the following process.

[0101] During the training process, the actual distance between the pupil of the user's face and the sight mark is detected by the second sensor; when the actual distance does not match the target distance, the distance deviation between the actual distance and the target distance is determined; it is determined that the distance deviation between the actual distance and the target distance is less than the adjustable distance of the electronic slide rail for the training lens in the deviation direction of the axial direction of the handheld bracket; the electronic slide rail is controlled to move the training lens along the axial direction of the handheld bracket so that the user's pupil is aligned with the position of the training lens.

[0102] This embodiment introduces a mechanism for automatically adjusting the position of the training lenses, which detects the distance between the user's pupil and the sight mark during the training process and makes adjustments based on actual conditions.

[0103] The second sensor can continuously monitor the distance between the user's pupil and the sight mark during the vision training process. The sight mark can be a fixed target point that the user needs to focus on during the vision training and keep a specific distance from it to ensure effective training.

[0104] When the actual distance does not match the target distance, the distance deviation is determined. If the second sensor detects that the actual distance between the user's pupil and the sight mark is inconsistent with the preset target distance, the distance deviation between the two can be calculated. This deviation is used to measure whether the user is in the correct training position.

[0105] Next, it can be checked whether the calculated distance deviation is within the adjustable range of the electronic slide rail. If the distance deviation is within the adjustable range of the slide rail, the device can automatically adjust the position of the training lens.

[0106] When it is determined that the deviation is within the adjustable range of the electronic slide rail, the system will control the electronic slide rail to automatically adjust the training lens along the axial direction of the handheld bracket, so that the user's pupil is realigned with the training lens, ensuring that the user can maintain the correct distance from the sight mark.

[0107] In this embodiment, by continuously monitoring the distance between the user's pupil and the sight mark and automatically adjusting the position of the training lenses, it can ensure that the user is always at the correct training distance, avoiding a decrease in training effect due to improper position, and automatically adjusting the lens position according to actual conditions. There is no need for the user to frequently manually adjust the distance of the device, which reduces the complexity of user operations and makes training easier and smoother.

[0108] During the entire training process, the user can maintain a consistent distance from the sight mark, ensuring the stability of the training and the repeatability of the effect. This is very important for users who need to train for a long time, especially when the user's position is slightly offset during the training process, it can be automatically corrected.

[0109] The automatic adjustment function makes the device smarter and the user experience more friendly. Especially for users such as children, the automatic correction function can effectively reduce the need for them to repeatedly adjust the position during training, improving the comfort of training.

[0110] Even if the user's posture changes slightly during training, it can dynamically adapt and automatically adjust to ensure that the user is always in the correct training state. This flexibility improves the system's adaptability to the actual usage environment.

[0111] In some embodiments, after the user is reminded to turn the visual trainer to align the user's pupil with the training lens angle to start training based on the deflection angle through the sound device, the electronic slide is controlled to move the training lens along the axial direction of the handheld bracket to align the user's pupil with the training lens position. The speed at which the electronic slide moves the training lens can be set according to actual needs. During the training process, the moving speed of the electronic slide is greater than the sliding speed before the training, which can make the electronic slide respond faster and adjust automatically faster during the training process, improve the user experience, and reduce the probability of user misoperation.

[0112] In some embodiments, the vision trainer also includes a data collection module and a network module; after the user is reminded by a sound device to rotate the vision trainer based on the deflection angle so that the user's pupil is aligned with the training lens angle to start training, the vision training method also includes: collecting training data through the data collection module; after the training is completed, sending the collected training data to the user terminal through the network module.

[0113] The main function of the data collection module is to collect various data of the user during the visual training process, such as the user's pupil position, the distance between the pupil and the sight mark, the training time, the number of training times, etc. These data can help analyze the user's training status, progress and training effect.

[0114] When the training is finished, the visual trainer sends the collected data to the user terminal, such as a smartphone, tablet or computer, through a network module, such as Wi-Fi, Bluetooth, cellular network, etc. The user terminal may be the user's own device or the doctor's / trainer's device for viewing and analyzing the training results.

[0115] The user terminal can display these training data and further use them to analyze the user's training progress, adjust the training plan, etc. For example, the user can view the training report in the mobile app, and the doctor or trainer can also conduct remote evaluation and guidance based on the uploaded data.

[0116] In this embodiment, by automatically collecting and uploading training data, real-time feedback can be provided, which helps users or professionals better understand the progress and problems in the training process, so as to make targeted adjustments and improvements to improve the training effect. Through the network module, the training data can be saved to the user terminal or cloud system, avoiding the risk of data loss. Users can check past training records at any time and track long-term training effects.

[0117] For users who need remote monitoring and guidance, such as patients undergoing rehabilitation training, by sending training data to remote doctors or trainers, the latter can make professional recommendations based on the data and provide personalized guidance.

[0118] The collected training data can be used to analyze the user's visual training effect, so as to further optimize and personalize the training plan. For example, if the data shows that the user's progress in certain aspects is slow, the trainer or doctor can automatically or manually adjust the training difficulty and mode to ensure more efficient training.

[0119] The user terminal can automatically process the received data, such as generating training reports, counting the user's training trends, and even predicting the user's future training progress through algorithms. This reduces the burden of manual recording and improves efficiency.

[0120] Users do not need to manually record the training process, all data is automatically collected and uploaded, simplifying the use process. This is especially helpful for children or elderly users, because they are usually not good at manually managing equipment or recording training data.

[0121] The vision training device provided by the present invention is described below. The vision training device described below and the vision training method described above can be referenced to each other.

[0122] like Figure 4 As shown, the vision training device according to the embodiment of the present invention mainly includes a first detection module 410 , a first processing module 420 , a second processing module 430 , a second detection module 440 and a third processing module 450 .

[0123] The first detection module 410 is used to detect the relative position of the user's pupil with respect to the training lens through a first sensor; The first processing module 420 is used to determine the deviation information of the user's pupil relative to the center of the training lens based on the relative position of the user's pupil relative to the training lens; The second processing module 430 is used to remind the user to move the vision training device through a sound device based on the deviation information so that the user's pupil is aligned with the training lens position; when the user's pupil is aligned with the training lens position, the projection of the user's pupil on the plane corresponding to the training lens is located within the range of the training lens; The second detection module 440 is used to detect the facial features of the user through the second sensor when the user's pupil is aligned with the training lens position, and determine the deflection angle of the vision trainer relative to the user's face; The third processing module 450 is used to remind the user to turn the vision trainer through a sound device based on the deflection angle so that the user's pupil is aligned with the training lens angle to start training; when the user's pupil is aligned with the training lens angle, the plane where the user's pupil is located is parallel to the plane corresponding to the training lens.

[0124] According to the visual training device provided by the embodiment of the present invention, the relative position of the user's pupil and the training lens is detected by the first sensor, and whether the pupil is aligned with the lens can be monitored in real time. An accurate prompt is given by the sound device to remind the user to adjust the position of the visual trainer in time, thereby ensuring that the position of the user's eyes is always within the effective training range of the training lens during the training process. After the pupil is aligned with the training lens, the second sensor detects the user's facial features to determine the deflection angle of the visual trainer. When an angle deviation is detected, the user is prompted to turn the trainer by sound to ensure that the user's line of sight remains parallel to the lens, thereby further improving the accuracy of the training and avoiding the interference of the angle deviation on the training effect. The user does not need to rely on manual or visual judgment, which reduces the difficulty of complex operations and alignment processes and improves the overall user experience. The user does not need to have professional technical knowledge to complete the training preparation work, so that the training posture meets the requirements, ensures the standardization and consistency of the training, and avoids fluctuations in training quality caused by alignment or angle deviation.
