[0023] As shown in the drawings, the visual trainer of the present application comprises a handheld support 110, and a visual target 120 and a training lens 130 mounted on the handheld support 110. Figure 1

[0024] The visual target 120 is mounted on one end of the handheld support 110, and the training lens 130 is mounted on the outer wall surface of the handheld support 110. The visual target 120 is used to display a target pattern, and the training lens 130 comprises a pair of detachable spectacle lenses located on one side of the handheld support 110.

[0025] The visual trainer further comprises a first sensor 140 and a second sensor 150 mounted on the handheld support 110. The first sensor 140 is used to detect the relative position between the position of the user's pupil and the training lens 130 to obtain the relative position of the user's pupil with respect to the training lens. The second sensor 150 is used to detect the facial features of the user and the distance from the training lens 130 to determine the posture of the user's face with respect to the visual trainer.

[0026] ​The handheld stand 110 is a main component of the visual trainer, which can be held by the user. The user can easily carry and move the visual trainer without location restrictions, increasing the flexibility of use. Handheld use makes the operation intuitive and easy to understand, and the user can quickly start training without complex setup or installation process.

[0027] The handheld stand 110 allows the user to adjust the position and angle of the visual trainer according to their own comfort, improving the degree of personalization of training. The user can also adjust the position of the handheld stand 110 at any time according to different training scenarios and needs to adapt to different training content.

[0028] Handheld use can increase the interaction between the user and the trainer, making the training process more active and engaging, suitable for users of different ages and ability levels.

[0029] Compared with visual training equipment that needs to be fixed and installed, handheld visual trainers are generally less expensive and more suitable for individual users and small-scale use.

[0030] The design of handheld visual trainers also makes visual training more flexible, convenient and personalized, while also improving the accessibility and user-friendliness of training.

[0031] The target 120 is installed at one end of the handheld stand 110 and is used to display the target pattern. The target 120 can be a display screen or a printed pattern, used to guide the user's gaze, for example, the target 120 can be an electronic target 120 to display the "E" letter.

[0032] As shown in Figure 1 The training lenses 130 can be installed on the outer wall of the handheld stand 110, and the training lenses 130 include a pair of detachable eyeglass lenses. These lenses may have specific optical properties, such as the degree for correcting vision, or lenses for simulating specific visual conditions.

[0033] The first sensor 140 is used to detect the user's pupil position and the relative position between the pupil and the training lenses 130. The second sensor 150 is used to detect the user's facial features and the distance from the training lenses 130 to determine the user's posture relative to the visual trainer.

[0034] To achieve real-time detection of the user during use, the first sensor 140 and the second sensor 150 are installed on the same side of the handheld stand 110 as the target 120. The data collected by the first sensor 140 is used to determine the alignment of the user's pupil and the training lenses 130, which is crucial for ensuring the effectiveness of visual training. The data collected by the second sensor 150 is used to determine the orientation and distance of the user's face, which can determine the user's posture, which helps to adjust the training lenses or the target 120 to adapt to the user's posture.

[0035] The first sensor 140 is an existing structure and is directly applied to this application. It can be any of an image sensor, a photoelectric sensor, or an eye tracker. When using an image sensor, a high-resolution image sensor can be used in conjunction with image processing algorithms to identify and track the position of the pupil. The camera captures an image of the user's eyes, and image processing algorithms (such as edge detection, feature point detection, etc.) are used to identify the position of the pupil and calculate the distance and angle of the pupil relative to the training lens 130. These are existing technologies inherent to image sensors and will not be elaborated upon.

[0036] When using an eye tracker, the device determines the pupil's position by recording eye movements and infers the eye's relative position to the training lens 130 by calculating the eye's position and angle. An eye tracker is a device used to measure and record eye movements. It tracks the eye's trajectory to detect the gaze point, blink frequency, and eye rotation angle. Eye trackers typically include high-precision sensors and cameras that capture subtle changes in the eye using infrared light or other optical technologies. These are existing technologies inherent in eye trackers and will not be elaborated upon further.

[0037] During this process, the user can hold the handheld support 110 so that the visual target 120 is on the left side. An eye tracker can then monitor the user's eye movements, detecting whether the user's pupils are aligned with the training lens 130, or whether the user's pupils are focused in the direction of the visual target 120. Once the user begins training, eye movement data can be continuously tracked and recorded.

[0038] The second sensor 150 is an existing structure and is directly applied to this application; specifically, it can be a depth camera or a facial recognition sensor. The second sensor 150, such as a depth camera or facial recognition sensor, can detect the user's facial features. These features typically include landmark facial points such as eyes, nose, and mouth, used to analyze the user's facial posture. The user's facial posture relative to the visual trainer can be determined by detecting the positional relationship of these points.

[0039] This invention relates to a vision trainer for visual training, which may include vision correction, stereoscopic vision training, and eye-tracking control training. Since the training lens 130 is detachable, users can replace it with lenses of different prescriptions or types as needed. Furthermore, the inclusion of the first sensor 140 and the second sensor 150 allows the trainer to adapt to different users' training positions and postures. In addition, the data collected by the first sensor 140 and the second sensor 150 can be used to adjust the training program in real time or for subsequent analysis to evaluate training effectiveness and user progress.

[0040] According to the visual trainer provided by the utility model, the target 120 and the training lens 130 are integrated on the handheld support 110, so that the user can conveniently realize visual training in multiple modes, the first sensor 140 and the second sensor 150 are arranged, the visual training tool can be adjusted according to the pupil position of the user and the facial posture of the trainer, the visual training accuracy and effect can be improved when the user holds the training lens.

[0041] In some embodiments, the visual trainer of the utility model further comprises different types of replacement training lenses 131 for replacement, and the replacement training lenses 131 are installed on the handheld support 110.

[0042] The visual trainer is equipped with multiple types of replacement training lenses 131, and these lenses have different optical properties, such as different degrees, focal lengths or specific vision correction functions. The replacement training lenses 131 can be conveniently installed and removed, allowing the user to replace the appropriate lens at any time according to the training requirements or personal vision changes. Different replacement training lenses 131 can adapt to different users' vision problems, such as myopia, hyperopia, astigmatism, etc., and different training goals, such as improving focusing ability, eye muscle coordination or stereoscopic vision.

[0043] Because different types of lenses can be replaced, the same visual trainer can be used by multiple users or by one user at different stages, increasing the versatility and practicality of the trainer. By selecting the appropriate replacement training lens 131, the user can obtain more accurate visual training, thereby improving the training effect and satisfaction.

[0044] In some embodiments, the training lens and the replacement training lens 131 are respectively installed on both sides of the handheld support 110, and each of the training lens and the replacement training lens 131 is respectively installed on the mounting ring 112, which is rotatably sleeved on the outside of the handheld support 110 to rotate the training lens 130 and the replacement training lens 131.

[0045] The training lens 130 and the replacement training lens 131 are respectively installed on both sides of the handheld support 110, so that the user can conveniently select and use them as needed. Each lens is installed on an independent mounting ring 112, and this design allows the lens to be flexibly adjusted in position on the handheld support 110. The mounting ring 112 can be rotatably sleeved on the outside of the handheld support 110, which means that the user can rotate the training lens 130 and the replacement training lens 131 by rotating the mounting ring 112 to adjust to the appropriate position. The user can easily rotate the mounting ring 112 according to the training needs or personal preferences, switching or adjusting the direction and angle of the lens. This design improves the adaptability of the visual trainer, allowing the same device to adapt to different training scenarios and user needs.

[0046] The mounting ring 112 generally comprises a ring structure, which can be made of durable materials such as metal or plastic, for securing and connecting the lenses. The mounting ring 112 can also include one or more securing devices that allow it to be mounted on the handheld holder 110 or other components on the handheld holder 110.

[0047] In some embodiments, the handheld holder 110 is equipped with an electronic slide rail 111, which is used to drive the mounting ring 112 to move the training lenses 130 and replacement training lenses 131 along the axial direction of the handheld holder 110.

[0048] The electronic slide rail 111 integrated on the handheld holder 110 is an electrically driven guide rail that can accurately control movement. The electronic slide rail 111 is responsible for driving the mounting ring 112, which carries the lenses, to move along the axial direction of the handheld holder 110 (i.e., along the length of the holder). Through the movement of the electronic slide rail 111, the positions of the training lenses 130 and replacement training lenses 131 can be adjusted to adapt to different visual training needs. The electronic slide rail 111 system allows precise control of the movement of the lenses, including speed and distance, thereby improving the accuracy and efficiency of the training. This design allows the adjustment of the lenses to be completed through automated operation, reducing the need for manual operation and improving the convenience of use.

[0049] In some embodiments, the visual trainer of the present application further comprises a sound emitting device 160 mounted on the outer wall of the handheld holder 110, which is used to emit sound prompts or instructions. For example, the sound emitting device 160 can be a loudspeaker or the like.

[0050] The sound emitting device 160 is used to emit sound prompts or instructions to help users follow the correct steps for training. For example, it can prompt the user when to adjust the viewing angle or change the training mode.

[0051] In some embodiments, the visual trainer of the present application further comprises a sound collecting device 170 mounted on the outer wall of the handheld holder 110, which is used to receive user sound feedback or instructions. The sound collecting device 170 can be a microphone or the like.

[0052] The sound collecting device 170 receives user sound feedback or instructions, which can help the device adjust the training settings or interact according to user feedback.

[0053] The bottom outer wall surface of the handheld support 110 is sleeved with a silica gel sleeve 180 for holding. The silica gel sleeve 180 generally has good softness and elasticity, can increase the holding comfort of the handheld support 110, and reduce hand fatigue when used for a long time. The silica gel material also has good anti-skid properties, can maintain stable holding even in hand sweat or humid environment, and prevents the handheld support 110 from slipping off.

[0054] The bottom end of the handheld support 110 is also provided with a charging port 190 for charging the visual trainer.

[0055] It can be understood that a power supply component such as a battery can be arranged in the visual trainer to supply power. The charging port 190 can be used to charge the battery to facilitate the use of the visual trainer.

[0056] The visual trainer can also integrate an electronic integration module, which can be built into the lower half of the handheld support 110. The electronic integration module can internally include an AI intelligent control system. When the user issues an instruction, the visual trainer can switch the training module, which is convenient for operation. When the user completes the training, the network card will upload the training data of the day to the background system, including the training time and the number of training times. The user can check the training data through the software background.

[0057] In addition, it should be noted that the above-mentioned sensors and other modules are directly applied by the present application without improvement, and are directly used for work with their own functions, which are prior art.

[0058] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. The specification and examples given are considered exemplary only, and the true scope and spirit of the application is indicated by the appended claims.
