Description

Technical Field

[0001] This invention relates to the field of visual function training technology, and in particular to a myopia prevention and control training device. Background Technology

[0002] Currently, myopia, astigmatism, and visual function abnormalities are quite common among teenagers. Existing myopia prevention and control methods mainly rely on medication, orthokeratology lenses, general vision training software, or single vision training programs. While these methods can slow myopia progression or help improve eye function to some extent, they still suffer from limitations in applicability, monotonous training content, lack of dynamic adjustment during training, and difficulty in providing systematic training for different visual functions.

[0003] In existing vision training devices or software, training images are typically displayed as preset patterns or fixed interfaces. Parameters such as the number, position, motion state, display size, display sequence, depth parameters, parallax parameters, and left / right eye display content often lack a unified generation and control mechanism, making it difficult to automatically generate corresponding training targets and form corresponding training images based on different training modes. Furthermore, some training systems can only provide ordinary 2D display or simple image switching, failing to effectively combine display processing methods such as separate left / right eye display, binocular display, training content exchange display, and naked-eye 3D display. This results in insufficient correspondence between training images and visual training objectives, and weak continuity and targeting in the training process. Summary of the Invention

[0004] In this section, as well as in the abstract and title of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title of this application, and such simplifications or omissions shall not be used to limit the scope of the invention.

[0005] To address the shortcomings of existing technologies, one objective of this invention is to provide a myopia prevention and control training device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a myopia prevention and control training device, comprising a control module for generating training images; and a display processing module for displaying the training images; wherein the control module is used to generate corresponding training targets according to preset training modes, and control the display parameters of the training targets to form training images corresponding to different preset training modes.

[0007] In a preferred embodiment of the myopia prevention and control training device of the present invention, the display processing module is used to perform left and right image synthesis processing on the training image to obtain a left-eye display image for the left eye to observe and a right-eye display image for the right eye to observe.

[0008] In a preferred embodiment of the myopia prevention and control training device of the present invention, the display processing module is used to switch the left eye display image and the right eye display image according to a preset switching rule.

[0009] As a preferred embodiment of the myopia prevention and control training device of the present invention, the left eye display image includes a left eye-specific image area and a first binocular common image area, and the right eye display image includes a right eye-specific image area and a second binocular common image area. The first binocular common image area and the second binocular common image area are used to present the same training content to both eyes.

[0010] In a preferred embodiment of the myopia prevention and control training device of the present invention, the left eye dedicated image area is used to display the first training content, the right eye dedicated image area is used to display the second training content, and the display processing module is used to switch the first training content and the second training content according to the preset switching rules.

[0011] As a preferred embodiment of the myopia prevention and control training device of the present invention, the training target includes at least one of graphics, dots, letters, numbers and symbols; the display parameters of the training target include at least one of quantity, display position, movement direction, movement speed, display size, display sequence, display duration, depth of field parameter, parallax parameter and left and right eye display content.

[0012] In a preferred embodiment of the myopia prevention and control training device of the present invention, the control module is used to adjust the display parameters according to the preset difficulty level so that the training difficulty increases or decreases step by step.

[0013] In a preferred embodiment of the myopia prevention and control training device of the present invention, the control module is used to control the training target to be displayed in at least one of the following ways: flashing in a random order, appearing at a random position, or being randomly rearranged.

[0014] As a preferred embodiment of the myopia prevention and control training device of the present invention, it further includes an interaction module, which is connected to the control module and is used to receive at least one of touch input, swipe input and key input to trigger training start, training mode switching, difficulty adjustment, depth of field adjustment or left and right eye display content switching.

[0015] As a preferred embodiment of the myopia prevention and control training device of the present invention, it further includes a display terminal, which is connected to the display processing module and is used to display the training image after display processing. The display terminal is a naked-eye 3D flat panel or a naked-eye 3D display device.

[0016] The beneficial effects of the myopia prevention and control training device of the present invention are as follows: The present invention, by setting up a control module and a display processing module, enables the control module to generate corresponding training targets according to preset training modes and control the changes in the display parameters of the training targets to form training images corresponding to different preset training modes; then, the display processing module processes the training images to output them in a manner suitable for the corresponding training mode. Thus, the present invention establishes a correspondence between training modes, training targets, display parameters, and training images, so that different training items no longer rely solely on fixed images or a single interface display, but can adjust the number of training targets, display position, movement direction, movement speed, display size, display sequence, display duration, depth parameters, parallax parameters, and left and right eye display content according to training needs, thereby improving the richness, relevance, and continuity of training content.

Detailed Implementation

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0041] In this invention, the preset training mode 600 can be understood as the training logic type invoked by the training system when starting a training project. The training target 101 can be understood as a graphical object on the display terminal 400 that is viewed, recognized, tracked, remembered, clicked, or compared by the user. The training image 102 can be understood as a display screen formed by the control module 100 based on the training target 101 and its display parameters. The display parameters are not components independent of the training target 101, but rather a set of parameters used to limit how the training target 101 is presented in the training image 102.

[0042] Example 1

[0043] Reference Figure 1 and Figure 5 This embodiment provides a myopia prevention and control training device, including a control module 100 and a display processing module 200. The control module 100 may be a processor located in a display terminal 400, a training program module running in the processor, or a control unit composed of a processor, a memory, and a training program. The display processing module 200 may be an image processing program, an image compositing SDK calling unit, a graphics rendering engine, or a combination thereof, and it is communicatively connected to the control module 100 via a software interface or a system bus.

[0044] The control module 100 pre-stores multiple preset training modes 600, each corresponding to a set of training target generation rules and a set of display parameter control rules. When a user enters a training item, the control module 100 first identifies the preset training mode 600 corresponding to the current training item, and then generates a training target 101 based on that preset training mode 600. The training target 101 can be a graphic, a dot, a letter, a number, a symbol, or a combination thereof. For example, in visual memory training, the training target 101 can be multiple randomly flashing graphics; in linear motion training, the training target 101 can be a dot or letter moving along a predetermined direction; in partial visual field training, the training target 101 can be a central letter or symbol and its surrounding auxiliary graphics.

[0045] After generating training target 101, control module 100 continues to call display parameters corresponding to the current preset training mode 600. Display parameters are used to limit the display state of training target 101 in training image 102, including but not limited to quantity, display position, movement direction, movement speed, display size, display sequence, display duration, depth parameters, disparity parameters, and left and right eye display content. Therefore, training target 101 is not directly equivalent to training image 102, but rather training image 102 is formed by combining training target 101 with display parameters. The same training target 101, under different display parameters, can form training images 102 with different difficulties, different display formats, or different visual stimulation methods.

[0046] After training image 102 is formed, control module 100 outputs training image 102 to display processing module 200. Display processing module 200 performs display processing on training image 102, including normal image rendering, left and right image compositing, depth of field adjustment, parallax adjustment, local 3D display processing, and allocation or combination of display content for left and right eyes. The processed training image 102 can be further output to display terminal 400 for display. The above settings establish a clear technical chain between training content design, parameter change control, and display processing. That is, preset training mode 600 determines the type of training target 101, display parameters determine the presentation mode of training target 101, training target 101 and display parameters together form training image 102, and display processing module 200 then completes the final display processing according to the display requirements of training image 102.

[0047] The control module 100 centrally manages the training objectives 101 and display parameters, enabling different training items to be generated and scheduled in the same device according to a unified data structure. This avoids the problem in existing vision training software where each item is displayed in isolation, making it difficult to form a systematic training process. The display processing module 200 performs subsequent processing on the training image 102, enabling the training image 102 to adapt to different output formats such as naked-eye 3D display, left and right eye separate display, and binocular display, thereby improving the pertinence and continuity of myopia prevention and control training.

[0048] Reference Figure 2 After receiving the training image 102, the display processing module 200 processes the training image 102 into a left-eye display image 201 for the left eye to observe and a right-eye display image 202 for the right eye to observe, based on the left and right eye display content, disparity parameters, depth parameters or preset display templates in the training image 102.

[0049] In this embodiment, the left and right image synthesis processing refers to the process by which the display processing module 200 allocates left and right eye display channels to the training content in the training image 102 according to the left and right eye display content, disparity parameters, depth parameters and / or preset display templates in the training image 102, and forms a left eye display image 201 and a right eye display image 202 respectively.

[0050] Specifically, the left-right image synthesis process does not simply stitch or superimpose two images. Instead, it configures the training content that needs to be observed by the left eye alone to the left-eye display image 201, configures the training content that needs to be observed by the right eye alone to the right-eye display image 202, and configures the training content that needs to be observed by both eyes to the corresponding areas in the left-eye display image 201 and the right-eye display image 202 respectively. When it is necessary to form a depth of field or stereo parallax effect, the position, size, brightness, sharpness or display sequence of the corresponding training content in the left-eye display image 201 and the right-eye display image 202 are differentiated according to the parallax parameter or depth of field parameter.

[0051] Specifically, the display processing module 200 can first read the target object and its display parameters in the training image 102, and then generate left and right display images according to the image synthesis rules provided by the naked-eye 3D display device or 3D flat panel. For training projects that require the left and right eyes to view different content, the display processing module 200 configures a part of the training content in the left-eye display image 201 and another part of the training content in the right-eye display image 202; for training projects that require both eyes to view the same training content, the display processing module 200 can configure the same or corresponding image content in the left-eye display image 201 and the right-eye display image 202; for training projects that require depth of field or stereoscopic parallax, the display processing module 200 sets appropriate horizontal offset, brightness difference, sharpness difference or content difference between the left-eye display image 201 and the right-eye display image 202 to form the desired stereoscopic display effect.

[0052] For example, in depth training F3, the display processing module 200 can generate the same graphic target in both the left-eye display image 201 and the right-eye display image 202, and adjust their relative positions to create inner or outer depth effects. Similarly, in the left- and right-eye split-view scenarios of 3D reading training F9 or Hart table training F12, the display processing module 200 can allow one eye to view text content while the other eye views a blank image or different text content, thus providing the user with differentiated visual stimuli during binocular coordination.

[0053] This embodiment processes the training image 102 into a left-eye display image 201 and a right-eye display image 202, enabling the training device to support ordinary two-dimensional training, binocular split vision training, and three-dimensional fusion training on a single training platform. This maintains the uniformity of the training image 102 generated by the control module 100 and also improves the adaptability of the display processing module 200 to different training objectives.

[0054] Reference Figure 3This embodiment describes the region structure of the left-eye display image 201 and the right-eye display image 202. The left-eye display image 201 includes a left-eye-specific image region 201a and a first binocular shared image region 201b. The right-eye display image 202 includes a right-eye-specific image region 202a and a second binocular shared image region 202b. The left-eye-specific image region 201a carries training content for observation only by the left eye, and the right-eye-specific image region 202a carries training content for observation only by the right eye. The first binocular shared image region 201b and the second binocular shared image region 202b present the same training content to both eyes.

[0055] In actual display, the first binocular shared image region 201b and the second binocular shared image region 202b can have the same content, the same coordinate range, or matching display positions, allowing the user's eyes to jointly observe the training content on the same visual plane. The left-eye exclusive image region 201a and the right-eye exclusive image region 202a can be located on either side, above or below, or in other preset positions of the binocular shared region, and their positions are determined by the display parameters in the training image 102.

[0056] For example, refer to Figure 14 and Figure 15 In the balance training F16, the letters in the upper row can be viewed by the right eye, the letters in the lower row by the left eye, and the middle row by both eyes. In this embodiment, the middle row can be configured in the first shared binocular image area 201b and the second shared binocular image area 202b; the upper and lower rows are configured in the right-eye exclusive image area 202a and the left-eye exclusive image area 201a, respectively. Similarly, in the binocular vision training F20, letters visible only to the left eye, letters visible only to the right eye, and text visible to both eyes can be simultaneously presented using the aforementioned area structure.

[0057] By simultaneously setting dedicated areas and shared areas in the left and right eye display images, the display processing module 200 can not only achieve simple left and right separate vision, but also achieve combined training of separate vision and same vision, thus being suitable for various training purposes such as binocular balance, fusion stability, binocular fixation, and differential stimulation of the left and right eyes.

[0058] Example 2

[0059] Reference Figure 2 and Figure 3This embodiment further illustrates the preset switching rule 601 based on embodiment 1. The preset switching rule 601 can be stored in the control module 100 or called as a display processing parameter of the display processing module 200. The preset switching rule 601 is used to specify the switching conditions, switching timing, switching object, and display state after switching between the left-eye display image 201 and the right-eye display image 202.

[0060] In one implementation, the preset switching rule 601 is a user-triggered switching rule. When the user inputs a left-click, right-click, double-arrow key, or touch switching command through the interaction module 300, the display processing module 200 switches the left-eye display image 201, originally output to the left-eye channel, to the right-eye channel, and simultaneously switches the right-eye display image 202, originally output to the right-eye channel, to the left-eye channel. This method is suitable for training programs that require left-right eye reversal stimulation, such as central fixed parallax training F17, fixational latent strabismus training F21, and binocular radiation training F22.

[0061] In another implementation, the preset switching rule 601 is a staged switching rule. The control module 100 can determine the switching timing based on the training rounds, number of completions, fixation stabilization time, or user operation results. When a training round is completed, the control module 100 sends a switching command to the display processing module 200, causing the left-eye display image 201 and the right-eye display image 202 to be swapped. This avoids the user receiving only unilateral stimulation for a long time and promotes balanced training between the left and right eyes.

[0062] In another embodiment, the preset switching rule 601 may also include a rule that keeps the common content unchanged and only exchanges the differing content. For example, when both the left-eye display image 201 and the right-eye display image 202 include content areas for binocular viewing, the display processing module 200 only exchanges the left-eye exclusive content and the right-eye exclusive content when performing the switching, while keeping the binocular common content unchanged. This allows for differential stimulation of the left and right eyes based on binocular co-fixation, avoiding unnecessary jumps in the common fixation point or common training content.

[0063] By abstracting the control of switching between the left and right eye display content into a preset switching rule 601, multiple training projects can share the same switching logic, reducing the complexity of training project development; at the same time, the content received by the left and right eyes can be changed while maintaining the overall stability of the training image 102, thereby improving the targeting of training for binocular coordination, fusion and visual stability.

[0064] Example 3

[0065] Reference Figure 3This embodiment further illustrates the interchangeable display of the first training content 102a and the second training content 102b. The left-eye dedicated image region 201a is used to display the first training content 102a, and the right-eye dedicated image region 202a is used to display the second training content 102b. The first training content 102a and the second training content 102b can be text, letters, symbols, graphics, line segments, cursors, fixation points, a portion of a radiation image, or a portion of a three-dimensional training object.

[0066] In the initial state, the display processing module 200 outputs the first training content 102a to the left-eye dedicated image region 201a of the left-eye display image 201, and the second training content 102b to the right-eye dedicated image region 202a of the right-eye display image 202, according to the left and right eye display content carried by the training image 102. When the preset switching rule 601 is triggered, the display processing module 200 causes the first training content 102a and the second training content 102b to be swapped in display, that is, the first training content 102a is switched to be displayed in the right-eye display image 202, and the second training content 102b is switched to be displayed in the left-eye display image 201.

[0067] It should be noted that the "display swap" in this embodiment does not necessarily change the spatial definition of the left-eye dedicated image region 201a or the right-eye dedicated image region 202a itself, but rather changes the training content displayed in the two regions. The regions can exist as fixed display containers, and what is actually swapped is the first training content 102a and the second training content 102b.

[0068] This implementation method is applicable to the left and right eye separation sub-items in 3D reading training F9, Hart table training F12, central fixed parallax training F17, fixational latent strabismus training F21, and binocular radiation training F22. In these training programs, users typically need to first complete fixation, recognition, or stabilization training in a left-right eye allocation state, and then switch the content received by the left and right eyes using the left and right keys or other triggering methods to obtain reverse stimulation and binocular balanced training effects.

[0069] Example 4

[0070] Reference Figure 4 This embodiment further illustrates the training objective 101 and display parameters. The training objective 101 may include at least one of graphics, dots, letters, numbers, and symbols. Graphics may be squares, circles, triangles, stars, rhombuses, pentagons, crescents, hearts, flowers, or other recognizable patterns; dots may be ordinary dots, flashing dots, numbered dots, or movable balls; letters and numbers may be used for Hart chart training, visual memory training, brain memory training, sequential memory training, stereoscopic visual acuity training, and stereoscopic character visual acuity training; symbols may be used for children's training or training scenarios where letters are not suitable.

[0071] Display parameters include at least one of the following: quantity, display position, movement direction, movement speed, display size, display sequence, display duration, depth of field parameter, parallax parameter, and content displayed to the left and right eyes. Quantity limits the number of training targets 101 that appear simultaneously or sequentially, for example, gradually increasing from one graphic to nine graphics. Display position limits the coordinates, area, or range of appearance of the training target 101 on the screen; for example, the training target 101 may appear in the center area, edge area, or random area. Movement direction limits the movement of the training target 101 from left to right, from right to left, from top to bottom, from edge to center, or along a curve. Movement speed limits the speed at which the training target 101 moves or rotates.

[0072] Display size limits the size of training targets 101. For example, in half-field training F15, stereoscopic visual acuity training F18, and stereoscopic character visual acuity training F19, letters or symbols can be gradually reduced in size to increase training difficulty. Display timing limits the order in which multiple training targets 101 appear. For example, in visual memory training F1, multiple graphics flash in a random order; in sequential memory training F6, multiple numbers or words are first displayed in sequence and then randomly rearranged. Display duration limits the duration for which training targets 101 are continuously displayed, such as 200ms, 500ms, 800ms, or 1500ms. Depth of field and parallax parameters limit the effect of 3D display or local parallax display. Left / right eye display content limits whether a certain training content is viewed by the left eye, right eye, or both eyes.

[0073] The aforementioned display parameters can serve as a parameter table or configuration item when the control module 100 generates the training image 102. After the control module 100 reads the current training mode, it can call the corresponding parameter combination according to the training mode. In this way, the same training objective 101 can be reused in multiple training modes, while different training modes can form differentiated training images 102 through different display parameters, thereby improving the system's scalability.

[0074] Example 5

[0075] Reference Figure 4 This embodiment illustrates the method for adjusting preset difficulty levels. The control module 100 can set at least two preset difficulty levels, such as level one, level two, and level three. Each difficulty level corresponds to a set of display parameters. When training begins, the control module 100 can determine the initial difficulty level based on the user's training stage, historical training results, user selection, or system default values.

[0076] In one implementation, Level 1 difficulty corresponds to a smaller number of training targets 101, a larger display size, a slower motion speed, a longer display duration, and a smaller parallax parameter; Level 2 difficulty increases the number of training targets 101, reduces the display size, or increases the motion speed based on Level 1; Level 3 difficulty further increases the number of targets, shortens the display duration, speeds up the motion, and increases the depth of field or parallax variation range.

[0077] For example, in Visual Memory Training F1, Level 1 displays 1 to 3 images, Level 2 displays 4 to 6 images, and Level 3 displays 7 to 9 images, with the flashing order of the images randomly generated. In Fast Visual Training F2, Level 1 allows for a lower frequency of dot appearance, Level 2 increases the frequency, and Level 3 increases the number of dots or shortens the dot duration. In Linear Motion Training F7, the difficulty level can be achieved by increasing the speed of the movement.

[0078] The control module 100 can also automatically adjust the difficulty based on the training results. For example, when the user's accuracy rate exceeds a preset threshold in several consecutive training rounds, the control module 100 increases the difficulty level; when the user's error rate is high or the response time is too long, the control module 100 decreases the difficulty level or maintains the current level. This makes the training process adaptive, avoiding overly difficult training that makes it impossible to complete, and also avoiding overly easy training that leads to insufficient stimulation.

[0080] This embodiment illustrates the specific method by which training target 101 is randomly displayed. Control module 100 can control the training target 101 to flash in a random order, appear at a random position, or be randomly rearranged using random number generation rules or pseudo-random sequences. The random rules can be determined based on the current training project, training stage, and difficulty level.

[0081] In the visual memory training F1, the control module 100 first generates multiple graphics in the training image 102, and then controls the graphics to flash sequentially in a random order. After the flashing ends, all graphics become clickable again, and the user needs to click the graphics in the memorized flashing order. The control module 100 compares the user's clicking order with the random flashing order, outputs a correct or incorrect prompt, and decides whether to proceed to the next round based on the result.

[0082] In the rapid visual training F2, the control module 100 sets a gaze point at the center of the screen and generates dots at random locations around the center point. The user needs to keep their gaze on the center point while using peripheral vision to find the dots and eliminate them through touch. The location, timing, and number of dots can all be changed according to the difficulty level.

[0083] In the sequential memory training F6, the control module 100 first displays numbers or words in rows according to a preset order, and then after a brief blackout, randomly rearranges these targets to different positions in the training image 102, requiring the user to click in the previously memorized order. This random rearrangement prevents the user from relying solely on the target positions to complete the training, but requires them to actually memorize the target content and their order.

[0084] By increasing the uncertainty of training through random display mechanisms, users' mechanical memory of fixed positions and sequences is reduced, making training closer to the actual visual recognition, visual tracking, and spatial localization process.

[0085] Example 7

[0086] Reference Figure 1 , Figure 5 and Figure 6 This embodiment describes the interaction module 300. The interaction module 300 is connected to the control module 100 and is used to receive at least one of the user's touch input, swipe input, and key input. The interaction module 300 can be a touchscreen input unit, physical buttons, virtual buttons, directional keys, a swipe gesture recognition unit, a voice prompt confirmation unit, or a combination thereof.

[0087] After receiving input, the interaction module 300 sends the input event to the control module 100. The control module 100 executes corresponding actions based on the type of input event and the current training state. Touch input can be used to click on the training target 101, trigger the start of training, confirm the training result, or fix the position of the training image; swipe input can be used to zoom in or out on letters, switch training content, adjust the display size, or adjust the difficulty; button input can be used to switch between left / right eye display content, randomly change letters, adjust the depth of field, enter the next round of training, or return to the training interface.

[0088] For example, in Depth of Field Training F3, the left arrow adjusts the inner depth of field, and the right arrow adjusts the outer depth of field. Touching a target fixes the image position, allowing users to gradually increase or decrease the depth of field parameters. In Hart Table Training F12, swiping right randomly changes the letter, swiping left shrinks the letter, and the left and right keys switch between left and right eye content in split-view training. In Half-Field Training F15, random key presses change letters or symbols, and swiping adjusts the size of letters or symbols.

[0089] By connecting the interaction module 300 to the control module 100, this invention not only passively displays the training image 102, but also dynamically adjusts the training process according to user operations. This setting allows training mode switching, difficulty adjustment, depth-of-field adjustment, and switching of left and right eye display content to all be completed within the same interactive framework, improving the operability and continuity of the training process.

[0090] Example 8

[0091] Reference Figure 5 This embodiment describes a display terminal 400. The display terminal 400 is connected to the display processing module 200 and is used to display the training image 102 after display processing. The display terminal 400 can be a naked-eye 3D flat panel, a naked-eye 3D display screen, a display device with left and right eye image guidance structure, or an intelligent display device that can call a 3D synthesis SDK.

[0092] In one embodiment, both the control module 100 and the display processing module 200 are located within the display terminal 400. The processor within the display terminal 400 runs a training program. In the training program, the control module 100 generates a training image 102. The display processing module 200 calls the image compositing interface provided by the display terminal 400 to complete left and right image compositing, parallax adjustment, or depth-of-field adjustment, which is then output to the display screen of the display terminal 400.

[0093] In another embodiment, the control module 100 is located in an external host or server, and the display processing module 200 is located in the display terminal 400. The control module 100 sends the training image 102 or training parameters to the display terminal 400, and the display terminal 400 completes image processing and display. This method is suitable for scenarios involving multi-terminal training or centralized management of training data.

[0094] When the display terminal 400 is a naked-eye 3D flat panel, the user can observe the training content after left and right image synthesis without wearing special glasses. By combining naked-eye 3D display with training target 101, display parameters and preset switching rules 601, depth training, left and right eye separate vision training, binocular joint training and local parallax training can be realized, improving the performance of training image 102 in myopia prevention and control training.

[0095] Example 9

[0096] Reference Figure 6 This embodiment illustrates the interface navigation and training control process of the myopia prevention training device. After system startup, the main training interface 500 is first displayed. The main training interface 500 includes a function entry point and a training entry point. The function entry point is used to access function interfaces related to user information, operating instructions, or system settings, while the training entry point is used to access training interfaces related to myopia prevention training. The control module 100 receives trigger operations on the function entry point or training entry point and enters the corresponding interface or training process based on the triggered entry point.

[0097] When a user triggers a training entry, the system displays the training interface corresponding to that entry and determines a preset training mode 600 based on the selected training item. The control module 100 generates a corresponding training target 101 based on the preset training mode 600 and controls the display parameters of the training target 101 to form a training image 102. The display processing module 200 processes the training image 102 and outputs it for display to perform corresponding myopia prevention training.

[0098] In one specific implementation, the function entry points include a user login button 501 and an operation guide button 502, and the training entry points include an overall vision function improvement training button 503 and a myopia training button 504. When a user triggers the user login button 501, the system displays the user login interface 501a; when a user triggers the operation guide button 502, the system displays the operation guide interface 502a; when a user triggers the overall vision function improvement training button 503, the system displays the overall vision function improvement training interface 503a, and generates a corresponding training target 101 based on the selected training item in this interface, controls the change of the display parameters of the training target 101 to form a training image 102, and outputs the training image 102 after display processing; when a user triggers the myopia training button 504, the system displays the myopia training interface 504a, determines the preset training mode 600 based on the selected training item in this interface, generates a corresponding training target 101, controls the change of the display parameters of the training target 101 to form a training image 102, and outputs the training image 102 after display processing to execute training items related to myopia training.

[0099] The overall visual function improvement training interface 503a and the myopia training interface 504a are not simple menu pages, but rather entry points for selecting training modes. The former mainly corresponds to the training programs from spatial motion training F14 to before, focusing on the overall improvement of visual memory, visual motion, eye movement, visual perception, dynamic vision, and fusion ability; the latter mainly corresponds to the training programs from semi-field training F15 to semi-field symbol training F23 after spatial motion training F14, focusing on myopia, astigmatism, and binocular vision-related training.

[0100] This method allows users to access login, guide, and two types of training entry points directly from the main training interface 500, making the process clear. At the same time, after entering a training project, the technical chain of the aforementioned control module 100, training target 101, display parameters, and display processing module 200 is still invoked, thereby ensuring the consistency between interface interaction and training image generation logic.

[0101] Example 10

[0102] In this embodiment, the function entry point includes a user login button 501. (Refer to...) Figure 7When a user triggers the login button 501, the system displays the login interface 501a. The login interface 501a includes an account input area E1, a password input area E2, a login control E3, and a registration control E4. The account input area E1 is used to receive usernames, mobile phone numbers, or other account information; the password input area E2 is used to receive passwords or verification codes; the login control E3 is used to submit a login request; and the registration control E4 is used to access the registration interface 501b.

[0103] When a user triggers the registration control E4, the system displays the registration interface 501b. Registration interface 501b may include input areas for name, age, gender, phone number, WeChat ID, or other identity information, and may display an "Immediate Login" button E5. After completing the registration information input, the user can submit the information via the registration button; if the user already has an account or wishes to return to the login interface, they can trigger the "Immediate Login" button E5, causing the system to switch from registration interface 501b to user login interface 501a.

[0104] By setting up a user login interface 501a and a registration interface 501b, the system can associate user identity with training records, vision data, training stage, and training difficulty. This not only facilitates different users using the same training device independently, but also makes it easier for the subsequent control module 100 to call up appropriate preset training modes 600 and display parameters based on the user's historical training information.

[0105] Example 11

[0106] Reference Figure 8 and Figure 9 This embodiment illustrates the user information flow after successful login. After successful login, the user login button 501 on the main training interface 500 is updated to a user information button 505. In response to the triggering operation of the user information button 505, the system displays the user information interface 505a. The user information interface 505a can display the user's name, age, gender, contact number, account information, and relevant vision data entry.

[0107] A button 505b for relevant vision data is set in the user information interface 505a. When the user triggers the button 505b, the system displays the user vision information interface 505c. The user vision information interface 505c is used to receive user vision information editing operations. The vision information may include pre-correction right eye myopia, left eye myopia, right eye astigmatism, left eye astigmatism, and other vision description information, and may also include corresponding data after correction.

[0108] In response to the trigger operation of the save control E6, the system saves the user's vision information and displays the training stage selection interface 505d. The training stage selection interface 505d may include options such as Stage I and Stage II. After the user selects a training stage, in response to the trigger operation of the confirm control E7, the system returns to the main training interface 500.

[0109] User information, vision information, and training stage selection results can serve as a reference for the control module 100 to select the training difficulty level, training item order, and display parameters. For example, for stage I users, a lower difficulty level and a larger display size can be used; for stage II users, the number of targets, movement speed, disparity parameters, or the display size can be gradually increased. This combines basic user information with training image generation rules, improving the individual adaptation capability of the training process.

[0110] Example 12

[0111] In this embodiment, the function entry point includes an operation guide button 502. (Refer to...) Figure 10 When the user triggers the operation guide button 502, the system displays the operation guide interface 502a. The operation guide interface 502a is used to centrally display the operation instructions for each training item, so that the user can understand the training purpose, operation actions, precautions and switching methods before formal training.

[0112] The operation guide interface 502a can display the operation instructions for the following training orders or categories: Visual Memory Training F1, Rapid Visual Training F2, Depth of Field Training F3, Brain Memory Training F4, Hand-Eye Coordination Training F5, Sequential Memory Training F6, Linear Motion Training F7, 3D Motion Training F8, 3D Reading Training F9, Time Visual Training F10, Circle Space Training F11, Hart Table Training F12, Sagging Training F13, Spatial Motion Training F14, Semi-field Training F15, Balance Training F16, Central Fixed Parallax Training F17, Stereotype Vision Training F18, Stereo Character Vision Training F19, Binocular Vision Training F20, Fixational Latent Strabismus Training F21, Binocular Radiation Training F22, and Semi-field Symbol Training F23.

[0113] Furthermore, in this embodiment, the operation instructions for each training item displayed in the operation guide interface 502a may include the following: Reference Figure 11The operation instructions for Visual Memory Training F1 include: Control module 100 generates multiple training targets 101 in training image 102. Each training target 101 can be at least one of the following: a graphic, a dot, a letter, a number, or a symbol. Control module 100 controls the multiple training targets 101 to flash sequentially in a random order, prompting the user to remember the flashing order of each training target 101. After the flashing ends, control module 100 re-displays the multiple training targets 101 in training image 102, prompting the user to click on the corresponding training targets 101 in the remembered flashing order. Control module 100 outputs a result prompt based on whether the user's click order matches the flashing order, and increases the number of training targets 101, shortens the display time, changes the display position, or increases the complexity of the flashing order according to the preset difficulty level. Thus, through the combination of random flashing, sequential memory, and click feedback, the user is guided to perform visual memory, eye movement, and spatial positioning training.

[0114] Reference Figure 11 The operation instructions for the F2 rapid visual training method include: the control module 100 sets a central fixation point in the training image 102 and randomly generates dots, letters, numbers, or shapes around the central fixation point as training targets 101; prompting the user to keep their gaze on the central fixation point and observe the randomly appearing training targets 101 through peripheral vision; when the user finds a training target 101, they can click and eliminate the training target 101 through touch input, and the control module 100 outputs a confirmation prompt after the user's correct touch; after one round of training, the control module 100 can display the result information and prompt the user to touch the central fixation point again to start the next round of training. The control module 100 can gradually increase the frequency, number, display range, or shorten the display duration of the training targets 101 according to the training rounds. Thus, through the combination of central fixation, peripheral observation, and rapid touch, the user's peripheral visual recognition speed and visual-motor coordination ability are improved.

[0115] Reference Figure 11The operation instructions for Depth of Field Training F3 include: the control module 100 generates a vector image, a target image, or other training target 101 capable of forming depth perception, and forms a training image 102; the display processing module 200 performs left and right image compositing processing on the training image 102 to generate a left-eye display image 201 and a right-eye display image 202, and forms a three-dimensional depth of field effect through depth parameters and parallax parameters. Depth of Field Training F3 can include external depth of field training and internal depth of field training. When performing external depth of field training, the control module 100 controls the training target 101 to present a visual effect of protruding outward from the display terminal 400 through display parameters. The user adjusts the external depth of field step by step using the right arrow, external depth of field adjustment control, or corresponding buttons; when the user touches the training target 101, the control module 100 fixes the display position of the training target 101, and continues to increase or decrease the depth of field difficulty step by step after the position is fixed. During inner depth training, the control module 100 controls the training target 101 to present a visual effect of being recessed towards the display terminal 400 through display parameters. The user adjusts the inner depth step by step using the left arrow, the inner depth adjustment control, or the corresponding button, and continues to increase the difficulty after the image stabilizes. Thus, through alternating training of outer and inner depth, the user's binocular fusion ability, depth positioning ability, and stereoscopic spatial judgment ability are improved.

[0116] Reference Figure 11 The operating instructions for Brain Memory Training F4 include: the control module 100 displays words, numbers, letter combinations, or symbol combinations in the training image 102, and hides or switches the training target 101 after a preset display duration; prompts the user to input previously displayed content in a designated input area based on memory; the control module 100 outputs result prompts based on the consistency between the user's input and the previously displayed content, and gradually increases the word length, number of digits, number of characters, or shortens the display duration according to a preset difficulty level. For example, it can start with a 3-letter word or a 3-digit number, gradually increasing to longer words or more digits. Thus, through the combination of short-term display, memory retention, and input feedback, the user's visual perception, visual memory, and recognition abilities for text, numbers, and symbols are trained.

[0117] Reference Figure 11The operation instructions for the F5 hand-eye coordination training program include: the control module 100 generates rotating dots, letters, numbers, or graphics as training targets 101 in the training image 102, and controls the training targets 101 to move clockwise, counterclockwise, radially, circumferentially, or other preset trajectories; prompting the user to quickly touch and eliminate the corresponding training targets 101 during their movement; the control module 100 outputs result prompts based on the user's touch accuracy, reaction time, and omission rate, and gradually increases the movement speed, rotation speed, number of displays, or complexity of the movement trajectory of the training targets 101. Thus, through the combination of dynamically displayed targets and touch-to-eliminate actions, the user's dynamic positioning ability, visual prediction ability, and hand-eye coordination ability are trained.

[0118] Reference Figure 11 The operation instructions for Sequential Memory Training F6 include: the control module 100 displays multiple numbers, letters, words, graphics, or symbols as training targets 101 in a preset order; after the display ends and a preset interval has elapsed, the control module 100 randomly rearranges the training targets 101 to different display positions in the training image 102; the user is prompted to click on the randomly rearranged training targets 101 in the previously memorized display order; the control module 100 outputs correct or incorrect prompts based on the click order, and gradually increases the number of training targets 101, shortens the memorization time, increases the rearrangement range, or improves the target similarity according to the training rounds. Thus, through the combination of sequential display, short-term memory, random rearrangement, and sequential clicking, the user's ability to memorize the sequence of visual information and their spatial retrieval ability are trained.

[0119] Reference Figure 11 The operation instructions for the Linear Motion Training F7 include: the control module 100 generates dots, balls, letters, numbers, or symbols as training targets 101, and controls the training targets 101 to move in the left-right, up-down, diagonal, or other linear directions; prompting the user to coordinate their eyes to track the movement trajectory of the training targets 101, causing their eyes to follow the movement of the training targets 101; the control module 100 gradually increases the movement speed of the training targets 101, changes the movement direction, shortens the display time, or increases the number of reciprocating movements according to the preset difficulty level. Thus, by guiding the user through eye-tracking training with linearly moving targets, it improves the ability of both eyes to move in the same direction, the ability to control movement trajectory, and the ability to dynamically follow visual movements.

[0120] Reference Figure 12The operation instructions for 3D motion training F8 include: the control module 100 generates small balls, dots, or other training targets 101 with numbers, letters, or symbols, and controls the training targets 101 to appear or move randomly in the training image 102; the display processing module 200 performs local parallax processing or left-right image compositing processing on the training targets 101 to make the training targets 101 present a three-dimensional display effect; prompting the user to read, recognize, or click on the three-dimensional training targets 101 in a preset order, such as quickly reading the numbered three-dimensional training targets 101 in ascending order of numbers; the control module 100 gradually increases the number of training targets 101, changes the display position, changes the movement speed, or adjusts the parallax parameters according to the preset difficulty level. Thus, through the combination of three-dimensional moving targets, active recognition, and increasing quantity, the user's stereoscopic visual perception ability, dynamic fusion ability, and spatial positioning ability are trained.

[0121] Reference Figure 12 The operation instructions for the 3D reading training F9 include: the display processing module 200 generates a left-eye display image 201 and a right-eye display image 202 based on the training image 102, allowing the left and right eyes to receive different image content respectively; the display image corresponding to one eye can display text, letters, sentences, or reading content, while the display image corresponding to the other eye can display blank content, auxiliary graphics, or different text content; prompting the user to read specified content, and triggering a preset switching rule 601 through the left button, right button, continue, random button, or other switching controls to switch the content displayed by the left and right eyes; the control module 100 can also increase the training difficulty by reducing the text size, increasing the number of texts, changing the reading content, or shortening the reading time. Thus, through the coordination of left-eye and right-eye separate reading and content switching display, the binocular coordination ability, the visual acuity of the weaker eye, and the convergence, accommodation, and fusion abilities during the reading process are trained.

[0122] Reference Figure 12 The operation instructions for the Time-Based Visual Training F10 include: The control module 100 outputs sound, rhythmic, or visual cues during training and starts timing from the moment the cues are output; it prompts the user to press the left button, right button, or designated touch area within a preset time; the control module 100 outputs a result prompt based on the time difference between the user's click and the prompt's timing, outputting a correct prompt if the user completes the operation within the preset time range, otherwise outputting an error prompt; the control module 100 can also shorten the allowable reaction time according to the training stage, for example, setting a longer reaction time in the first stage and a shorter reaction time in the second stage. Thus, through the coordination of sound rhythm, visual cues, and click responses, the user's rhythmic perception, reaction synchronization, and sensory integration abilities between vision and hearing are trained.

[0123] Reference Figure 12The operation instructions for the Circle Space Training F11 include: the control module 100 displays circles, double circles, concentric circles, or continuous circular trajectories in the training image 102, and prompts the user to draw along the circle area. Circle Space Training F11 can include a first sub-training and a second sub-training. In the first sub-training, the control module 100 displays a single circle, double circles, or circles side-by-side. The user draws within the circle using their finger, stylus, or other input method, ensuring the drawn trajectory does not exceed the circle boundary. After becoming proficient, the user can draw simultaneously within the left and right circles using their left and right hands respectively. The control module 100 outputs prompts based on whether the touch trajectory crosses the boundary, is continuous, and approaches the circle trajectory. In the second sub-training, the control module 100 displays a continuous circular trajectory. The user continuously draws overlapping lines along the circle, ensuring the lines coincide with the circular trajectory as much as possible and do not exceed the circle boundary. The control module 100 determines the training result based on the deviation between the drawn trajectory and the preset circle trajectory. Thus, through the first and second sub-training in the circular space, users' bilateral coordination, visual-motor coordination, and visual target-based hand spatial control are trained.

[0124] Reference Figure 12 The operation instructions for Hart table training F12 include: the control module 100 generates a character table containing multiple random letters, numbers, or symbols in the training image 102, and prompts the user to count or identify the number of identical characters. Hart table training F12 can include Hart table training I, Hart table training II, and Hart table training III. Hart table training I is a two-dimensional character statistics training. The control module 100 generates a character table composed of random letters, numbers, or symbols in the training image 102, and the user quickly counts the number of identical characters. The user can randomly change the character content by sliding to the right and reduce the character size by sliding to the left to gradually increase the training difficulty. Hart table training II is a three-dimensional character table training. The display processing module 200 performs left and right image compositing or local parallax processing on the character table to make at least some of the characters in the character table present a three-dimensional display effect. As the user continues to count the number of identical characters, the control module 100 can gradually shorten the counting time, reduce the character size, or randomly change the character content. Hart table training III is a left- and right-eye character training method. The display processing module 200 generates a left-eye display image 201 and a right-eye display image 202 based on the training image 102, and enables the left and right eyes to receive different character content respectively. Users can randomly change letters or characters by sliding, and trigger the preset switching rule 601 by using the left button, right button or other switching controls to exchange the display content between the left and right eyes. Thus, through the combination of two-dimensional character statistics, three-dimensional character fusion and left- and right-eye character training, the user's dynamic vision, character recognition ability and center fusion ability are improved.

[0125] Reference Figure 12 The operation instructions for saccade training F13 include: the control module 100 sets a central fixation point in the training image 102 and randomly displays marked targets on the left and right sides, top and bottom sides, or other areas of the training image 102. Saccasion training F13 can include saccade training I and saccade training II. In saccade training I, the control module 100 sets a central fixation point in the central area of ​​the training image 102 and randomly displays marked targets on letters, numbers, or symbols on the left and right sides of the screen, prompting the user to quickly switch their gaze between the central fixation point and the randomly appearing marked targets on the left and right sides; the control module 100 gradually increases the speed of marked target appearance, shortens the display duration, or increases random position changes according to the training time. In saccade training II, the user first clicks on the central fixation point in the training image 102, and the control module 100 then displays letters, numbers, or symbols at random positions on the screen. The user needs to quickly shift their gaze and identify the training target 101; after repeating the above operation, the control module 100 adjusts the training difficulty according to the user's response speed and recognition accuracy. Therefore, the F13 saccade training can train both the ability to quickly switch between center and periphery gaze and the ability to search for and recognize random targets after a click.

[0126] Reference Figure 12 The operation instructions for the spatial motion training F14 include: the control module 100 randomly generates different numbers of circles, letters, numbers, graphics, or symbols as training targets 101 in the training image 102, and controls the training targets 101 to appear from the edge of the screen, corner area, or random position; prompting the user to concentrate and track all training targets 101 by jumping with both eyes; the control module 100 gradually increases the number, appearance range, movement speed, direction change, or randomness of training targets 101 according to the preset difficulty level. Thus, through the combination of omnidirectional random target appearance, jumping tracking, and increasing number, the user's omnidirectional eye movement ability, spatial positioning speed, and multi-target tracking ability are trained.

[0127] Reference Figure 13 The operating instructions for the F15 half-field training include: the control module 100 displays a training target 101 centered on a letter in the training image 102, and displays a square or other auxiliary graphic with diagonal lines around the letter; prompts the user to fixate on the central letter, and determines whether the diagonal lines remain black, clear, and stable while recognizing the letter; the user can change letters by pressing random keys, and zoom in or out of the letters by sliding; the control module 100 determines the current training difficulty based on the smallest letter size that the user can stably recognize, and prompts the user to change the target or reduce the difficulty when the diagonal lines become lighter or unstable. Thus, through the coordination of the central letter and the surrounding diagonal lines, the user's visual acuity, half-field perception ability, and fixed-gaze stability are trained.

[0128] Reference Figures 14-16 The operation instructions for Balance Training F16 include: The display processing module 200 generates a left-eye display image 201 and a right-eye display image 202 based on the training image 102, and allows different display content to be viewed by the left eye, right eye, or both eyes simultaneously. Balance Training F16 can include ordinary balance training and children's balance training. Ordinary balance training is suitable for users who can recognize letters, and the training target 101 can be letters, numbers, or characters; children's balance training is suitable for users who cannot stably recognize letters but can recognize symbols or shapes, and the training target 101 can be geometric shapes, direction symbols, animal patterns, or other shapes that children can recognize. Both ordinary balance training and children's balance training can include three training parts. In the first part, the display processing module 200 generates a left-eye display image 201 and a right-eye display image 202, so that the two lines of gradually decreasing training content are viewed by both eyes respectively, for example, the upper line is viewed by the right eye and the lower line is viewed by the left eye; the user repeatedly observes until vision is stable, and can switch the display content between the left and right eyes using the left key, right key, or double arrow key. In the second part, training image 102 adds a middle row of content for both eyes to view together. The upper and lower rows are viewed by the right and left eyes respectively, while the middle row is viewed by both eyes. Users observe the upper and lower rows while keeping the middle row stable, and repeatedly switch between the left and right eye content. In the third part, training image 102 displays multiple columns of letters, symbols, or graphics. The middle column is viewed by both eyes, the two left columns by the left eye, and the two right columns by the right eye. Users change the training content using random buttons, zoom in or out using swipes, and switch the content displayed by the left and right eyes using the left and right keys. Thus, through general balance training and children's balance training, the Balance Training F16 can cater to users of different ages and recognition abilities, and improve binocular balance and fusion stability through the combination of monocular content and binocular content.

[0129] Reference Figure 17 The operation instructions for the central fixed parallax training F17 include: the control module 100 displays a square and a triangle with two vertices connected within the square in the training image 102; the display processing module 200 configures the upper triangle to be viewed by the right eye and the lower triangle to be viewed by the left eye; the user is prompted to fixate on the contact point of the two triangles and observe whether the two triangles remain black, stationary, and uniformly colored; when the image moves or becomes unstable, the user is prompted to continue fixing their gaze until the image stabilizes; once the image stabilizes, the user triggers a preset switching rule 601 using the left button, right button, or other switching controls to swap the content displayed by the left and right eyes. Thus, through central fixed gaze, left-right eye difference display, and content inversion training, the stability of binocular central gaze and binocular balance ability are improved.

[0130] Reference Figure 13The operation instructions for the stereoscopic visual acuity training F18 include: the control module 100 displays multiple rows of progressively smaller letters, numbers, or optotypes in the training image 102; the display processing module 200 performs local parallax processing on some rows or parts of the content to create a three-dimensional display effect, while retaining another part of the content as a two-dimensional display effect. The stereoscopic visual acuity training F18 can include convex optotype training and concave optotype training. In convex optotype training, the display processing module 200 makes some optotypes appear as a three-dimensional display effect protruding outwards from the display terminal 400, while retaining the middle rows or parts of the optotypes as a two-dimensional display effect; the user identifies the optotypes row by row and changes the optotype content by pressing random buttons. In concave optotype training, the user reverses the depth of field direction using internal keys, external keys, depth adjustment controls, or corresponding touch operations, switching the originally convex three-dimensional optotypes to a concave effect; the control module 100 automatically adjusts the three-dimensional difficulty level according to the training stage and increases the training difficulty by reducing the size of the optotypes. Therefore, by comparing two-dimensional and three-dimensional targets, as well as convex and concave targets, users' stereoscopic vision sharpness and visual acuity are improved.

[0131] Reference Figure 13 The operation instructions for the stereo character vision training F19 include: the control module 100 displays multiple lines of letters, numbers, or characters in the training image 102, where each line has at least one character that creates a three-dimensional display effect through local parallax processing, and the remaining characters can be two-dimensional characters. The stereo character vision training F19 can include convex character training and concave character training. In convex character training, the display processing module 200 makes some characters appear as three-dimensional characters protruding outwards from the display terminal 400, prompting the user to read each line of characters and identify the three-dimensional characters within them. In concave character training, the user reverses the depth direction of the three-dimensional characters using internal keys, external keys, or a depth-of-field switching control, switching convex characters to concave characters; the control module 100 can change the character content through random key presses, reduce the character size through sliding operations, and adjust the difficulty of the three-dimensional display according to the training stage. Thus, by comparing two-dimensional characters of different sizes and with three-dimensional characters of different depth directions, the user's ability to recognize stereo characters and their stereoscopic visual acuity are trained.

[0132] Reference Figure 18The operation instructions for the binocular vision training F20 include: the display processing module 200 combines letters visible only to the left eye, letters visible only to the right eye, and text or symbols visible to both eyes to form a training image 102; the left-eye display image 201 may include a left-eye exclusive image area 201a and a first binocular shared image area 201b, and the right-eye display image 202 may include a right-eye exclusive image area 202a and a second binocular shared image area 202b; the user is prompted to identify the content in different areas while viewing with both eyes simultaneously, and to zoom in or out of characters by sliding; the control module 100 can also adjust the character size, display position, or number of characters displayed according to the user's recognition performance. Thus, by synchronously displaying content visible only to the left eye, only to the right eye, and visible to both eyes, binocular vision training is achieved, along with convergence coordination and binocular visual stability.

[0133] Reference Figure 19 The operation instructions for the fixational latent strabismus training F21 include: the control module 100 displays a cross-shaped image with a center point and a circle in the training image 102; the display processing module 200 makes different segments or regions of the cross image viewed by the left and right eyes respectively, for example, the right eye views the upper right segment and the left eye views the lower left segment; the user is prompted to fixate on the center point and observe whether the cross arms remain black, stationary, and uniformly colored; when the image moves or becomes unstable, the user is prompted to continue fixating until it stabilizes; once the image stabilizes, the user triggers a preset switching rule 601 using the left and right keys to swap the content displayed by the left and right eyes. Thus, through the combination of central fixation, differential vision, and content switching, binocular visual stability is trained and central fixation ability is improved.

[0134] Reference Figure 20 The operating instructions for the F22 binocular radiation training system include: the control module 100 displays a radiation image with a center point in the training image 102; the display processing module 200 configures the upper half, lower half, or different ray regions of the radiation image for viewing by the left or right eye, for example, the right eye views the upper half and the left eye views the lower half; the user is prompted to fixate on the center point and observe whether all rays remain uniformly black and stationary; once the image stabilizes, the user triggers a preset switching rule 601 using the left and right keys, the switch button, or other controls to swap the content displayed by the left and right eyes. Thus, by using separate radiation images, central fixation in binocular co-op mode, and switching content between the left and right eyes, binocular fusion ability and stereoscopic stability are improved.

[0135] Reference Figure 13The operation instructions for the Partial Visual Field Symbol Training F23 include: the control module 100 displays the training target 101 centered on a symbol in the training image 102, and displays a square or other auxiliary graphic with diagonals around the symbol; the symbol can be a geometric symbol, directional symbol, simple pattern, or a child-recognizable graphic; the user is prompted to fixate on the central symbol and observe whether the surrounding diagonals remain black, clear, and stable while recognizing the symbol; the user can change the symbol by pressing random keys and zoom in or out of the symbol by sliding; the control module 100 determines the training result based on the smallest symbol size that the user can stably recognize and the clarity of the diagonals. Therefore, the Partial Visual Field Symbol Training F23 is suitable for users unfamiliar with letters and, together with the Partial Visual Field Training F15, forms a training method for partial visual field perception and visual acuity.

[0136] The operation instructions for each of the above training items can be displayed in the operation guide interface 502a in the form of text descriptions, graphic descriptions, pop-up descriptions, scrolling descriptions, or training item details pages. When the user selects any training item in the operation guide interface 502a, the control module 100 can display the corresponding operation instructions for that training item, and return to the main training interface 500, the overall visual function improvement training interface 503a, or the myopia training interface 504a after the user confirms. By centrally configuring the operation instructions for each training item in the operation guide interface 502a, users can understand the observation method, operation method, switching method, and difficulty change method of the training target 101 before entering training, thereby reducing misoperation and making the collaborative relationship between each training item and the control module 100, the display processing module 200, and the interaction module 300 clearer.

[0137] Example 13

[0138] In this embodiment, the training entry point includes an overall visual function improvement training button 503, and the training interface includes an overall visual function improvement training interface 503a. (Refer to...) Figure 11 and Figure 12 When the user triggers the Overall Visual Function Enhancement Training button 503, the system displays the Overall Visual Function Enhancement Training interface 503a. The Overall Visual Function Enhancement Training interface 503a is used to display and switch between the following training programs in a preset order: Visual Memory Training F1, Rapid Visual Training F2, Depth of Field Training F3, Brain Memory Training F4, Hand-Eye Coordination Training F5, Sequential Memory Training F6, Linear Motion Training F7, 3D Motion Training F8, 3D Reading Training F9, Time Visual Training F10, Circle Space Training F11, Hart Table Training F12, Sagging Training F13, and Spatial Motion Training F14.

[0139] In visual memory training F1, the control module 100 generates multiple graphics as training targets 101 and controls them to flash in a random order. The user clicks on the graphics in the order they are to be memorized. The difficulty can be increased by adding more graphics. In fast visual training F2, the control module 100 randomly generates dots around the center point. The user keeps their gaze on the center point and eliminates the dots by touch. In depth-of-field training F3, the display processing module 200 performs left-right image synthesis on the training image 102 and adjusts the depth-of-field parameters. The user adjusts the inner or outer depth of field using the arrow controls.

[0140] In Brain Memory Training F4, training target 101 can be a word or a number. Control module 100 controls the character length according to the difficulty level and requires the user to write it down in a designated area. In Hand-Eye Coordination Training F5, training target 101 can be a rotating dot, letter, or number. Control module 100 controls the rotation direction and speed, and the user quickly touches to eliminate it. In Sequential Memory Training F6, targets are first displayed in sequence and then randomly rearranged; the user clicks in the order they are to be remembered. In Linear Motion Training F7, targets move left and right or in other directions, with the movement speed increasing with difficulty.

[0141] In 3D motion training F8, the display processing module 200 performs local parallax processing, displaying numbered dots or balls in a 3D effect, with the control module 100 controlling the number of balls to increase. In 3D reading training F9, the display processing module 200 generates different images for the left and right eyes, allowing the user to switch between them using a preset switching rule 601. In time vision training F10, the control module 100 starts a timer based on sound or rhythm signals, and the user clicks a button within a specified time. In circle space training F11, the user draws a trajectory within a circle, and the interaction module 300 receives the drawing input. In Hart table training F12, the control module 100 generates a random array of letters and scales or rearranges them based on sliding operations. In saccade training F13, the target appears alternately on the left, right, or center areas, training the eye's saccade ability. In spatial motion training F14, the control module 100 controls different numbers of circles, letters, or numbers to appear randomly from the edge of the screen.

[0142] The overall visual function enhancement training interface 503a organizes various training items in a preset order, forming a continuous training chain from memory, peripheral vision, depth of field, visual perception, dynamic tracking to spatial positioning. This interface is not only a list of items, but also reflects the control logic of the control module 100 in calling different training objectives 101 and display parameters based on different training items.

[0143] Example 14

[0144] In this embodiment, the training entry point includes a myopia training button 504, and the training interface includes a myopia training interface 504a. (Refer to...) Figure 13When the user triggers the myopia training button 504, the system displays the myopia training interface 504a. The myopia training interface 504a is used to display and switch between the following training modes in a preset order: half-field training F15, balance training F16, central fixed parallax training F17, stereoscopic optotype vision training F18, stereoscopic character vision training F19, binocular vision training F20, fixational latent strabismus training F21, binocular radiation training F22, and half-field symbol training F23.

[0145] Furthermore, referring to Figure 13 The myopia training interface 504a can also display a vision level indicator S. The vision level indicator S represents the vision level, optotype level, character size level, or training difficulty level corresponding to the training target 101 in the current training image 102. As one implementation, the vision level indicator S can be displayed in numerical form such as 0.1, 0.12, 0.16, 0.2, 0.25, 0.32, 0.4, 0.5, 0.63, 0.8, and 1.0, or in the form of levels such as Level 1, Level 2, Level 3, Low, Medium, and High. The vision level indicator S is not limited to actual medical testing vision values; it can also serve as an internal indicator within the training system to differentiate the display size, depth of field intensity, parallax intensity, or recognition difficulty of the training target 101.

[0146] In one specific implementation, the control module 100 generates a corresponding visual acuity level identifier S based on the current training item, the training stage selected by the user, historical training results, or a preset difficulty level, and displays the visual acuity level identifier S above, to the side, near the training target 101, or in the training item title area of ​​the training image 102. When the user performs stereoscopic visual acuity training F18, stereoscopic character visual acuity training F19, binocular visual acuity training F20, partial visual field training F15, or partial visual field symbol training F23, the user can determine the visual acuity level or difficulty level of the current training target 101 based on the visual acuity level identifier S.

[0147] In one specific embodiment, the visual acuity level indicator S is associated with the display parameters of the training target 101. The control module 100 can adjust the display size, display position, disparity parameter, depth parameter, or left / right eye display content of the training target 101 according to the visual acuity level indicator S. For example, when the visual acuity level indicator S corresponds to a lower level, the control module 100 can control the training target 101 to be displayed at a larger size and set a smaller disparity parameter or a lower depth difficulty; when the visual acuity level indicator S corresponds to a higher level, the control module 100 can control the training target 101 to be displayed at a smaller size and increase the disparity parameter, depth parameter, or recognition difficulty. Thus, the visual acuity level indicator S is not only used to indicate the current training level to the user, but also serves as a reference for the control module 100 to adjust the display parameters.

[0148] In one specific implementation, when a user performs swipe input, key input, or touch input through the interaction module 300, the control module 100 can update the visual acuity level indicator S according to the user's operation. For example, when the user swipes left to shrink the training target 101, the control module 100 can switch the visual acuity level indicator S to a higher level; when the user reduces the difficulty or enlarges the training target 101, the control module 100 can switch the visual acuity level indicator S to a lower level. After training, the control module 100 can also record the highest visual acuity level indicator S that the user can stably recognize as the training result or stage result, and store it in association with the user's visual acuity information in the user's visual acuity information interface 505c.

[0149] By setting a vision level indicator S, the myopia training interface 504a can intuitively display the recognition level or training difficulty corresponding to the current training target 101, allowing users to understand the current training stage. At the same time, the control module 100 can progressively adjust the display parameters based on the vision level indicator S, so that training items such as half-field training F15, stereoscopic optotype vision training F18, stereoscopic character vision training F19, and binocular vision training F20 have a clearer hierarchical relationship, thereby improving the observability, recordability, and continuity of the training process.

[0150] In the half-field training F15 and half-field symbol training F23, the training target 101 can be a central letter or symbol and a square surrounded by diagonals. The control module 100 can change the letter or symbol by pressing random keys and zoom in or out of the letter or symbol by sliding input, allowing the user to judge the clarity of the letter or symbol and its surrounding diagonals when fixating on it.

[0151] In the balanced training F16, the display processing module 200 can configure the upper row content for right-eye viewing and the lower row content for left-eye viewing, and in another stage, add a middle row or column for both eyes to view. Through the combination of the left-eye dedicated image area 201a, the right-eye dedicated image area 202a, the first binocular shared image area 201b, and the second binocular shared image area 202b, synchronous display of content differing between the left and right eyes and content shared by both eyes can be achieved.

[0152] In the central fixed parallax training F17, training image 102 displays a square with two triangles connected by two vertices inside. The upper triangle can be viewed by the right eye, and the lower triangle by the left eye. The user fixates on the contact point and switches the content displayed to the left and right eyes after stabilization. In the stereoscopic optotype vision training F18, the upper and lower rows of letters can have a three-dimensional convex or concave effect, while the middle row can have a two-dimensional effect. Local parallax processing is used to compare two-dimensional and three-dimensional vision. In the stereoscopic character vision training F19, each row can be set with one three-dimensional convex letter, and the letter can be changed using a random key or slid to shrink the letter.

[0153] In binocular vision training F20, the display processing module 200 generates training image 102 by synthesizing content visible only to the left eye, content visible only to the right eye, and content visible to both eyes simultaneously. In fixational latent strabismus training F21, training image 102 can display a cross with a center point and a circle. The right eye views the upper right segment, and the left eye views the lower left segment. After stabilization, the content displayed by the left and right eyes is swapped. In binocular radial image training F22, the right eye views the upper half of the radial image, and the left eye views the lower half. After stabilization, the left and right keys are pressed to swap the displayed content.

[0154] The training programs in the myopia training interface 504a primarily utilize display processing methods such as left and right eye separate vision, binocular simultaneous display, content swapping, local parallax, depth of field adjustment, and size scaling. These methods, combined with user gaze, recognition, reading, and clicking actions, form a training process aimed at myopia prevention and improvement of binocular vision. By concentrating these training programs within the myopia training interface 504a, the system can continue with more targeted myopia-related training after overall visual function has improved.

[0155] The control module 100, display processing module 200, and interaction module 300 can be integrated into the same display terminal 400, or they can be set in different devices and connected via wired or wireless communication. The training target 101, training image 102, left-eye display image 201, right-eye display image 202, and their respective image regions can be proportionally adjusted according to the pixel size, viewing angle allocation method, and naked-eye 3D display method of the specific display device.

[0156] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
