[0002] With the rapid development of science and technology, brain-computer interface technology (BMI) has shown great potential in many fields such as medicine, education, and entertainment. Especially in the field of concentration training, brain-computer interface technology can provide users with personalized training programs by real-time monitoring and analysis of users' brain activities, thereby significantly improving the training effect. However, the existing concentration training equipment still has the following problems in use:

[0014] In a possible design, electromagnets are fixedly installed on the top inner walls of multiple adjustment grooves, and multiple electromagnets are rotatably sleeved on the outer walls of corresponding connecting rods.

[0017] In one possible design, a brain wave indicator light is fixedly installed on the top of the display screen. The brain wave indicator light is used to receive the user's brain-computer signals and display the user's concentration level by emitting light of different colors.

[0018] A training method of a concentration training device in cooperation with a brain-computer interface comprises the following steps:

[0019] S1. First, the concentration training device can be used by three people at the same time. When using it, the user can complete the connection between the brain-computer device and the training device while wearing the brain-computer device; the concentration training device can display the interactive software connected with the brain-computer on the display screen, and the user can interact with the content displayed on the display screen through the brain-computer, and can complete the training of their own concentration in turn;

[0020] S2. When the user is training, by starting the second motor, the second motor will drive the third gear to rotate, and the third gear will drive the rotating ring to rotate through the outer gear ring, thereby realizing the synchronous rotation of the inner gear ring; when the inner gear ring rotates, it will mesh with the three adjacent fourth gears, thereby completing the rotation drive of the three connecting rods; when the three connecting rods rotate, they will complete the lifting and lowering drive of the slider in the same lifting slot through the reciprocating screw connected to them, thereby completing the reciprocating lifting and lowering movement of multiple display screens; by making the display screen move continuously, the interference to the user can be increased when the user is performing brain-computer interaction, thereby increasing the difficulty of concentration training and enhancing the training effect;

[0021] S3. When the user energizes one of the electromagnets, the electromagnet will generate magnetic force and magnetically attract the moving block. At this time, the moving block will drive the fourth gear to rise, and the corresponding spring will also be compressed; when the fourth gear is completely separated from the inner gear ring, the connecting rod will no longer rotate, and the position of the corresponding display screen will no longer change, which is convenient for realizing the separate movement control of the display screen and can be convenient for changing different training methods for different users; when the electromagnet is powered off, the corresponding fourth gear will mesh with the inner gear ring again under the push of the spring rebound, and the adjustment of the display screen can be restored to meet the training needs of the user;

[0022] S4. When the user is training concentration, he or she can also use the cylindrical level to train in different ways; specifically, the user can control the corresponding first motor to start through brain-computer interaction, and the first motor will drive the second gear to rotate. Since the second gear is meshed with the first gear, the second gear can roll along the first gear, thereby allowing the display screen to rotate with the turntable as the center of rotation; when the display screen rotates, its bottom is no longer horizontal, so the bubbles in the cylindrical level will also move accordingly. The user can control the first motor through the brain-computer to adjust the horizontal posture of the display screen, so that the bubbles in the cylindrical level move to the middle of the cylindrical level, thereby completing the concentration training;

[0023] S5. When the user is training his concentration, the brain wave indicator light can receive brain-computer signals and display different colors according to the user's concentration level. The user and external personnel can judge the user's concentration level according to the color displayed by the brain wave indicator light, so as to adaptively adjust the training method and degree to ensure good training effect on the user's concentration.

[0024] Beneficial effects:

[0025] In the present invention, the concentration training device in cooperation with the brain-computer uses a display screen to interact with the user wearing the brain-computer device, which not only increases the fun and interactivity of the training, but also can adjust the training content and difficulty in real time according to the user's brain-computer signal to achieve personalized training. The design of multiple display screens allows multiple users to train at the same time, which can improve the efficiency of training.

[0026] In the present invention, the brain-computer-assisted concentration training device can realize the height adjustment of multiple display screens through the design of multiple lifting components and driving components, which can increase the interference factors in the training process and improve the difficulty and effect of training. At the same time, the rotation function of the display screen combined with the design of the cylindrical level can further enrich the training method, making the training more comprehensive and diverse, which is conducive to improving the fun and training effect of concentration training;

[0027] In the present invention, the concentration training device coordinated with the brain-computer interface realizes flexible control of the position of the display screen through the coordinated use of the electromagnet and the spring, and different display screens in the same device can be adjusted synchronously or individually, with good use effect. The user can adjust the height and angle of the display screen at any time according to their own needs, thereby improving the convenience and flexibility of training.

[0028] In the present invention, the brain-computer-assisted concentration training device allows users and outsiders to understand the user's concentration level in real time through the introduction of brain wave indicator lights, and make targeted adjustments according to the color changes of the indicator lights to ensure the optimization of the training effect;

[0029] In the present invention, the brain-computer combined concentration training device innovatively integrates display screen interaction, personalized training content adjustment, multi-user synchronous training, height and angle adjustable design, and brain wave real-time feedback mechanism, which not only enhances the fun interaction and personalized experience of training, but also increases the difficulty and diversity of training by flexibly adjusting the position and rotation function of the display screen. At the same time, the intuitive feedback of the brain wave indicator light helps to accurately adjust the training strategy, ensure the optimization of the training effect, and comprehensively improve the efficiency and effectiveness of the user's concentration training.

[0039] Example 1

[0040] Reference Figure 1-7 A concentration training device includes: a base 1, a support rod 2, a plurality of display screens 3, and corresponding lifting components and driving components.

[0041] First, the base 1 serves as the supporting foundation of the entire device, and a support rod 2 is fixedly installed on the top thereof. The outer wall of the support rod 2 is designed with a plurality of lifting grooves 4, and a slider 13 is slidably arranged inside each lifting groove 4. A connecting plate 12 is fixedly installed on one side of the slider 13 for connecting and supporting the display screen 3.

[0042] A mounting shell 16 is fixedly mounted on one side of the display screen 3, and a turntable 15 is rotatably connected to one side of each mounting shell 16. A rotating bracket 14 is fixedly mounted on the turntable 15, and the rotating bracket 14 is rotatably connected to the adjacent connecting plate 12, thereby realizing multi-angle adjustment of the display screen 3. The display screen 3 is used to interact with the user wearing the brain-computer device to assist the user in concentration training.

[0043] In order to adjust the height of the display screen 3, the embodiment is provided with multiple lifting assemblies. Each lifting assembly includes a reciprocating screw 5 rotatably arranged inside the lifting slot 4, one end of the reciprocating screw 5 is threadedly penetrated through the adjacent slider 13, and the slider 13 can be driven to slide up and down in the lifting slot 4 by rotating the reciprocating screw 5, thereby adjusting the height of the display screen 3.

[0044] In order to uniformly control multiple lifting components, a driving component is also provided in this embodiment. The driving component includes a fixed plate 6 fixedly sleeved on the outer wall of the support rod 2, a protective shell 7 is provided above the fixed plate 6, and a second motor 21 is installed in the protective shell 7. The output shaft of the second motor 21 is meshed and transmitted with the outer gear ring 25 of the rotating ring 23 through the third gear 22. The rotating ring 23 is rotatably sleeved on the outer wall of the support rod 2 and an inner gear ring 24 is fixedly installed on the top of the rotating ring 23, and the inner gear ring 24 is meshed with a plurality of fourth gears 28. A plurality of adjustment slots 20 are provided on the outer wall of the support rod 2, and each fourth gear 28 is located in the corresponding adjustment slot 20 and is slidably sleeved on the outer wall of the adjacent connecting rod 26 through a sliding slot slider, and can rotate synchronously with the connecting rod 26. The top of the connecting rod 26 is fixedly connected to the corresponding reciprocating screw rod 5, and the plurality of connecting rods 26 rotate and penetrate the corresponding adjustment slot 20. Therefore, when the second motor 21 is working, the plurality of reciprocating screw rods 5 can be driven to rotate simultaneously, so as to achieve the height synchronization adjustment of the plurality of display screens 3.

[0045] Furthermore, in this embodiment, the structure of the lifting assembly is optimized, and an electromagnet 30 and a spring 29 are added to achieve a more stable transmission effect. An electromagnet 30 is fixedly installed on the top inner wall of each adjustment slot 20, and the electromagnet 30 is rotatably sleeved on the outer wall of the corresponding connecting rod 26. An iron layer is provided on the top of the moving block 27, which is magnetically matched with the electromagnet 30. At the same time, a spring 29 is sleeved on the outer wall of the connecting rod 26, one end of which is fixedly connected to the bottom of the electromagnet 30, and the other end is fixedly connected to the top of the moving block 27. When the electromagnet 30 is energized, it attracts the moving block 27 to move up, so that the fourth gear 28 is separated from the inner gear ring 24, and the position of the corresponding display screen 3 is no longer controlled by the second motor 21; when the power is off, the spring 29 pushes the moving block 27 to move down, and the fourth gear 28 is meshed with the inner gear ring 24 again, which can maintain the stability of the transmission system.

[0046] In order to increase the fun and interactivity of the training, the present embodiment adds a cylindrical level 11 and a rotating mechanism at the bottom of the display screen 3.

The positioning hook 10 is located between the two fixed hooks 9 and in the middle of the cylindrical level 11, and one end of the positioning hook is designed as a tip for providing a center indication for the bubble in the level.

[0047] In addition, a first gear 17 is fixedly sleeved on the outer wall of the turntable 15, and a first motor 18 is fixedly embedded in the mounting shell 16. The output shaft of the first motor 18 is meshed with the first gear 17 through the second gear 19, thereby driving the display screen 3 to rotate with the turntable 15 as the rotation center. Users can train their concentration by observing the movement of bubbles in the cylindrical level 11, and combined with the interactive content of the display screen 3, the training is more vivid and interesting.

[0048] The present application can be used in the field of concentration training technology, and can also be used in other fields applicable to the present application.

[0049] Example 2

[0050] refer to Figure 1 , 4 , improved on the basis of Example 1: a brain-computer-assisted concentration training device, which is applied to the field of concentration training technology;

[0051] In order to intuitively display the user's concentration level, this embodiment adds an electroencephalogram indicator light 8 on the top of the display screen 3. The electroencephalogram indicator light 8 is used to receive the user's brain-computer signal and emit different colors of light according to the strength of the signal, thereby providing real-time feedback on the user's concentration state. For example, when the concentration level is high, the indicator light may emit green light; when the concentration level decreases, it turns yellow or red to remind the user to adjust the state.

[0052] Furthermore, the training equipment also includes EEG acquisition equipment and software applications. The EEG acquisition equipment uses advanced brain-computer interface (non-invasive) technology to collect and analyze EEG signals safely and accurately. The software application carries hundreds of rich training contents and a gamified training mode, making scientific training easy and interesting. The system will push appropriate training content and training difficulty according to the child's current ability level, easily improving brain abilities such as attention, reaction, memory, and self-control.

[0053] The training system includes three major training modules: brain relaxation training, neurofeedback training, and cognitive ability training. The training content is rich and interesting, such as level-breaking scenes, combined with 50+ game-based training content, to help children learn to focus while "playing". After each training session, children will receive corresponding gold coins and star rewards based on their training performance. Children can use the gold coins to exchange for gifts in the mall, or they can check the ranking of the training results for the day on the leaderboard page.

[0054] The system can also track the effects. In the report section, you can view the daily training report, which includes detailed information on brain-computer data. Through daily reports and stage reports, you can intuitively see the stage changes and growth changes of children, allowing users to intuitively see the training effects. The report includes the specific improvement effects of concentration, memory, self-control, and reaction, as well as a comprehensive review of training performance.

[0055] A training method of a concentration training device in cooperation with a brain-computer interface comprises the following steps:

[0056] S1. First, the concentration training device can be used by three people at the same time. When using it, the user can complete the connection between the brain-computer device and the training device while wearing the brain-computer device; the concentration training device can display the interactive software connected with the brain-computer on the display screen 3, and the user can interact with the content displayed on the display screen 3 through the brain-computer, and can complete the training of their own concentration in turn;

[0057] S2. When the user is training, by starting the second motor 21, the second motor 21 will drive the third gear 22 to rotate, and the third gear 22 will drive the rotating ring 23 to rotate through the outer gear ring 25, thereby realizing the synchronous rotation of the inner gear ring 24; when the inner gear ring 24 rotates, it will mesh with the three adjacent fourth gears 28, thereby completing the rotation drive of the three connecting rods 26; when the three connecting rods 26 rotate, they will complete the lifting and lowering drive of the slider 13 in the same lifting slot 4 through the reciprocating screw 5 connected thereto, thereby completing the reciprocating lifting and lowering movement of multiple display screens 3; by making the display screen 3 move continuously, the interference to the user can be increased when the user is performing brain-computer interaction, thereby increasing the difficulty of concentration training and enhancing the training effect;

[0058] S3. At the same time, when the user energizes one of the electromagnets 30, the electromagnet 30 will generate magnetic force and magnetically attract the moving block 27. At this time, the moving block 27 will drive the fourth gear 28 to rise, and the corresponding spring 29 will also be compressed; when the fourth gear 28 is completely separated from the inner gear ring 24, the connecting rod 26 will no longer rotate, and the position of the corresponding display screen 3 will no longer change, which is convenient for realizing the separate movement control of the display screen 3 and can be convenient for changing different training methods for different users; when the electromagnet 30 is powered off, the corresponding fourth gear 28 will mesh with the inner gear ring 24 again under the rebound push of the spring 29, and the adjustment of the display screen 3 can be restored to meet the training needs of the user;

[0059] S4. When the user is training concentration, he or she may also use the cylindrical level 11 to train in different ways; specifically, the user may start the corresponding first motor 18 through brain-computer interaction control, and the first motor 18 will drive the second gear 19 to rotate. Since the second gear 19 is meshed with the first gear 17, the second gear 19 can roll along the first gear 17, thereby allowing the display screen 3 to rotate with the turntable 15 as the rotation center; when the display screen 3 rotates, its bottom is no longer horizontal, so the bubbles in the cylindrical level 11 will also move accordingly, and the user may adjust the horizontal posture of the display screen 3 through brain-computer control of the first motor 18, so that the bubbles in the cylindrical level 11 move to the middle of the cylindrical level 11, thereby completing the training of concentration;

[0060] S5. When the user is training his concentration, the brain wave indicator light 8 can receive brain-computer signals and display different colors according to the user's concentration level. The user and external personnel can judge the user's concentration level according to the color displayed by the brain wave indicator light 8, so as to adaptively adjust the training method and degree to ensure good training effect on the user's concentration.

[0061] However, as is well known to those skilled in the art, the working principles and wiring methods of the display screen 3, the brain wave indicator light 8, the first motor 18, the second motor 21 and the electromagnet 30 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
