Description

Technical Field

[0001] The present invention relates to the technical field of glasses, and in particular to a pair of glasses for preventing and controlling myopia and correcting sitting posture and a control method thereof. Background Art

[0002] With the popularity of modern electronic products and changes in learning and working methods, people's long-term poor sitting posture and excessive use of eyes have become one of the main causes of myopia and spinal problems. In order to cope with this problem, a variety of sitting posture correction and vision protection products have appeared on the market.

[0003] Chinese patent publication number CN109212781A discloses a kind of smart glasses for posture correction reminder, which uses a level to facilitate identification of whether the user's sitting posture is correct; uses a vibration module to facilitate reminding the user to correct the sitting posture; reduces the induction probability of myopia and spinal curvature diseases; uses a Wi-Fi communication module to facilitate the interaction between the main processor module and external information; uses a data collection and analysis module to facilitate the analysis of the user's sitting posture trend. However, the above smart glasses mainly identify the sitting posture through a level and use a vibration module for reminders. The function is relatively single and lacks more comprehensive vision protection and eye health monitoring. Moreover, different users may have different sensitivities to vibration. If the vibration is too small, some people may feel that the vibration is not obvious enough, thereby ignoring the reminder; if the vibration is too large, it may affect others in a relatively quiet scene (such as a library). In addition, in some cases, such as when the user is performing delicate operations or needs to concentrate highly, the vibration reminder may interfere with the user's operation or attention.

[0004] Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Summary of the invention

[0019] Step S31, the processor chip 6 obtains the spacing value of the straight-line distance between the current head and the viewing direction, the first angle value of the viewing positive direction in the vertical direction, and the second angle value of the viewing positive direction in the horizontal direction through real-time calculation and conversion according to the positioning information, distance information, and head orientation information of the real-time motion trajectory of the head, and compares them with the preset standard spacing value, standard head vertical posture angle value, and standard head horizontal posture angle value;

[0029] 1. The glasses in this case monitor the eye distance in real time through distance sensors, and can detect the direction and posture of the wearer's head in real time through multi-axis sensors. When it detects that the eye distance is too close / too far or the sitting posture is incorrect, such as lowering the head or tilting the head, the processor chip will also issue instructions to intelligently guide the wearer to adjust by adjusting the backlight of the lens, which helps to cultivate correct eye posture and sitting habits, and reduce vision problems and spinal problems caused by bad posture.

[0030] 2. The distance sensor and multi-axis sensor of the method in this case can collect the user's distance information and head orientation information in real time. This information is received and processed by the processor chip to calculate the real-time movement trajectory and positioning of the head. Based on this information, the processor chip can determine whether the user's sitting posture and eye habits meet the health standards, and change the clarity of the lens by adjusting the lens backlight, thereby achieving the prevention and control of myopia and correction of sitting posture. In addition, by adjusting the lens backlight, the lens can be blurred so that the user can intuitively see that the line of sight is blocked, and thus immediately realize that the sitting posture is incorrect. And compared with vibration reminders, backlight reminders will not physically interfere with the user's body or operation.

[0031] 3. By setting the standard spacing value of 30cm, the standard head vertical posture angle value of 25°, and the standard head horizontal posture angle value of 10°, this implementation provides a clear and scientific benchmark for evaluating the user's sitting posture and head posture, which helps to ensure the accuracy and consistency of the evaluation results, thereby more effectively guiding the user to adjust the sitting posture and head posture. By setting the preset range values ​​including the spacing deviation range value of 30cm±10cm, the head down deviation range value of 25±10°, and the head tilt deviation range value of 10±10°, it not only takes into account the differences between individual users, but also ensures the flexibility of the evaluation, so that the method of this case can enable the system to adapt to the sitting habits of different users, while still being able to accurately identify the sitting posture problems that need to be corrected. By limiting when the difference between the user's head posture and the standard value exceeds the preset range, or when there are abnormal behaviors such as frequent up and down changes, the processor chip can quickly identify and send a warning signal to the buzzer, so that when the user is distracted or sleepy, he can also be aware of his sitting posture or head posture problems and take corresponding measures to adjust them.

The processor chip 6 may be a single-chip microcomputer chip. The distance sensor 4, the multi-axis sensor 5, and the processor chip 6 are communicatively connected or electrically connected to each other, and the processor chip 6 is communicatively connected or electrically connected to the lenses 3. In this way, the distance sensor and the multi-axis sensor can collect the wearer's eye behavior and head posture data in real time, and quickly transmit these data to the processor chip through a communication connection or an electrical connection. The processor chip can quickly process and analyze this data, thereby achieving real-time monitoring and intelligent correction of the wearer's eye behavior.

[0040] As mentioned above, the glasses in this case monitor the eye distance in real time through distance sensors, and can detect the orientation and posture of the wearer's head in real time through multi-axis sensors. When it detects that the eye distance is too close / too far or the sitting posture is incorrect, such as lowering the head or tilting the head, the processor chip will also issue instructions to intelligently guide the wearer to adjust by adjusting the backlight of the lens, which helps to cultivate correct eye posture and sitting habits, and reduce vision problems and spinal problems caused by bad posture.

[0041] As a preferred embodiment, the multi-axis sensor 5 is a six-axis sensor; the distance sensor 4 is an optical sensor. In this way, the six-axis sensor can simultaneously measure the force of an object in three directions and the torque or angular velocity, angular acceleration, etc. in three directions, and achieve high-precision multi-dimensional measurement capabilities, so that the glasses can accurately sense the wearer's head The tiny movements and posture changes.

[0042] As a preferred embodiment, the spectacle frame 1 is provided with a main frame 11 and two first protrusions 12 protruding backward from the left and right sides of the main frame 11, each of the first protrusions 12 is hinged to the temple 2; the processor chip 6 is installed inside one of the first protrusions 12. In this way, by forming the first protrusions 12 on the rear side of the main frame 11 of the spectacle frame 1, not only a hinge point is provided for the temple 2, but also the rear space is cleverly utilized to provide an independent installation space for the processor chip 6. Moreover, the independent installation space provides a certain heat dissipation space for the processor chip 6. This design improves the durability and reliability of the glasses.

[0043] As a preferred embodiment, a nose pad groove portion 112 is provided between the bottoms of the two annular lens ring portions 111, a first connecting portion 113 is formed above the nose pad groove portion 112 and is located between the tops of the two annular lens ring portions 111 to play a connecting role, and a raised connecting portion 114 is formed by protruding outward from the outermost tops of the two annular lens ring portions 111 to facilitate connection with the first protrusion 12; a first groove 115 is formed in each raised connecting portion 114, and the multi-axis sensor 5 is installed at the position of the first groove 115; the distance sensor 4 is installed at the position of the first connecting portion 113.

The first connecting portion 113 is located above the nose pad groove and between the tops of the two annular mirror rings, which plays a role of connection and stability, making the overall structure of the glasses frame more stable and not easy to deform. The convex connecting portion 114 is arranged to protrude outward from the outermost top of the annular mirror ring, which is convenient for connection with the first protrusion 12, not only enhancing the stability of the glasses leg. The arrangement of the first groove 115 formed by each convex connecting portion 114 provides an independent installation space for the multi-axis sensor 5, which is not only convenient for disassembly and assembly, but also enables the sensor to more accurately sense the wearer's head movements and posture changes, providing accurate data support for intelligent correction and monitoring. The arrangement of the distance sensor 4 installed at the position of the first connecting portion 113 makes it in the central position of the glasses, making full use of the space of the glasses frame while enabling the distance sensor to more directly and accurately measure the distance between the wearer's eyes and the target being viewed, providing effective data support for preventing myopia.

[0045] like Figure 4As shown, as a preferred embodiment, the lens 3 is provided with at least a backlight layer 31 with adjustable backlight and a dimming layer 32 with variable transparency. In this way, the backlight layer can be adjusted in coordination with the distance sensor 4, the multi-axis sensor 5, and the processor chip 6, so as to adjust the clarity and blur, so that when the user's sitting posture is not standard, the blur can be used to remind him to correct his sitting posture. The dimming layer 32 is provided so that the lens can automatically change its transparency according to the change of ambient light or temperature, so as to adjust the light transmittance of the lens according to the intensity of sunlight and protect the eyes from strong light damage.

[0046] As a preferred embodiment, the temple 2 is provided with two second grooves 21 for easy grasping at the front and rear ends of the inner side thereof, and a luminous layer 210 is coated on the surface of each second groove 21. In this way, the second grooves provided at the front and rear ends of the inner side of the temple and the luminous layer coating design improve the convenience of grasping and the visibility at night, making it more convenient for users to use.

[0047] Embodiment 2

[0048] like Figure 5 As shown, a control method for preventing and controlling myopia and sitting posture correction glasses is applied to the myopia prevention and control and sitting posture correction glasses described in Example 1, and the control method includes the following steps:

[0049] Step S1, collecting distance information in real time through the distance sensor 4, collecting head orientation information in real time through the multi-axis sensor 5, and sending them to the processor chip 6;

[0050] Step S2, the processor chip 6 calculates and records the information collected in real time in step S1 to obtain the real-time movement trajectory of the head and locate the movement trajectory of the head;

[0051] Step S3, the processor chip 6 obtains the current spacing value and angle value through real-time calculation and conversion according to the positioning information, distance information, and head orientation information of the real-time motion trajectory of the head, and compares them with the preset parameters; the processor chip 6 makes corresponding electrical signal feedback according to the comparison result, and changes the backlight in the interlayer of the upper lens 3 of the glasses by controlling the output change of the current according to the electrical signal feedback result;

[0052] Step S4: the lens 3 changes the backlight wavelength in the interlayer according to the intensity change of the output current, thereby changing the clarity of the lens.

[0053] As described above, the distance sensor and multi-axis sensor of the method of this case can collect the user's distance information and head orientation information in real time. This information is received and processed by the processor chip to calculate the real-time movement trajectory and positioning of the head. Based on this information, the processor chip can determine whether the user's sitting posture and eye habits meet the health standards, and change the clarity of the lens by adjusting the lens backlight, thereby achieving the prevention and control of myopia and correction of sitting posture. In addition, the lens backlight can be adjusted to blur the lens so that the user can intuitively see that the line of sight is blocked, so as to immediately realize that the sitting posture is incorrect. And compared with the vibration reminder, the backlight reminder will not physically interfere with the user's body or operation.

[0054] As a preferred implementation, the distance information is the straight-line distance between the head and the direction being looked at, acquired through real-time collection; the head orientation information includes: the angle between the direction being looked at by the head in the vertical direction and the angle between the direction being looked at and the horizontal direction. In this way, by limiting the specific contents of the distance information and the head orientation information, more comprehensive data support is provided to the processor chip, enabling it to more accurately judge the user's sitting posture and eye habits.

[0055] As a preferred implementation, step S3 includes:

[0056] Step S31, the processor chip 6 obtains the spacing value of the straight-line distance between the current head and the viewing direction, the first angle value of the viewing positive direction in the vertical direction, and the second angle value of the viewing positive direction in the horizontal direction through real-time calculation and conversion according to the positioning information, distance information, and head orientation information of the real-time motion trajectory of the head, and compares them with the preset standard spacing value, standard head vertical posture angle value, and standard head horizontal posture angle value;

[0057] Step S32, the processor chip 6 obtains the difference between the actual spacing value and the standard spacing value, the difference between the first angle value and the standard head vertical posture angle value, and the difference between the second angle value and the standard head horizontal posture angle value according to the comparison result;

[0058] Step S33: if all the differences do not exceed the preset range, it is determined that there is no need to correct the sitting posture, and there is no need to feed back the electrical signal result to the lens, and the lens maintains the original state;

[0059] If any of the differences exceeds the preset range and the duration of the non-compliant state is greater than the preset time, it is determined that the sitting posture needs to be corrected, and one or more non-compliant differences are comprehensively calculated to make corresponding electrical signal feedback, and one or more non-compliant differences are recorded and stored to determine the eye health status;

[0060] Step S34: According to the feedback result of the electric signal, the backlight in the interlayer of the lens 3 on the glasses is changed in real time by controlling the output change of the current.

[0061] As described above, by comparing the actual value with the preset value, the processor chip can more accurately identify the problem that needs to be corrected, and take corresponding measures to intervene, thereby improving the effect of preventing and controlling myopia and correcting sitting posture. By obtaining the current spacing value and angle value through real-time calculation and conversion, and comparing them with the preset parameters, the processor chip can accurately determine whether the user's sitting posture and eye habits meet the standards. For situations that do not meet the standards, the processor chip can make corresponding electrical signal feedback, and change the backlight in the lens interlayer by controlling the output change of the current, thereby adjusting the clarity of the lens. In addition, the method also has the function of recording and storing non-conforming standard deviation values, which provides data support for subsequent observations of whether one's sitting posture has improved, which is conducive to subsequent improvement of the effect of preventing and controlling myopia and correcting sitting posture. Moreover, step S33 specifically limits the judgment that the sitting posture needs to be corrected only when it is in a non-conforming state and the duration is greater than the preset time value, avoiding the situation where frequent misjudgments and frequent changes in blur affect the user's eyes, improving the correction accuracy while ensuring the safety of the user's eyes.

[0062] As a preferred embodiment, the following steps are also included: the lens 3 changes the transparency of the lens 3 according to temperature changes / environmental changes. This function enables the lens to adapt to different environmental conditions and user needs, further improving the practicality and comfort of the glasses. For example, in a strong sunlight environment, the lens can automatically reduce the transparency to reduce the stimulation of light to the eyes; in a dim environment, the lens can increase the transparency to improve the clarity of the field of vision. This adaptive adjustment function not only helps to protect the user's vision health, but also improves the overall performance of the glasses and user experience.

[0063] As a preferred embodiment, the standard spacing value is 30cm, the standard head vertical posture angle value is 25°, and the standard head horizontal posture angle value is 10°; the preset range values ​​in step S33 include: spacing deviation range value, set to 30cm±10cm; head down deviation range value, set to 25±10°; head tilt deviation range value, set to 10±10°; Figure 4 As shown, the spectacle frame 1 is also provided with a buzzer 7 which communicates with or is electrically connected to the processor chip 6;

[0064] Step S3 also includes the following steps:

[0065] When the difference between the acquired first angle value and the standard head vertical posture angle value is greater than 30° / the difference between the acquired second angle value and the standard head vertical posture angle value is greater than 30° / the difference between the first angle value and the standard head vertical posture angle value frequently changes up and down, it is determined that the user is in an abnormal state, such as the user is dozing off, and the processor chip 6 sends a warning signal to the buzzer 7, and the buzzer 7 starts.

[0066] As described above, by setting the standard spacing value of 30cm, the standard head vertical posture angle value of 25°, and the standard head horizontal posture angle value of 10°, this implementation provides a clear and scientific benchmark for evaluating the user's sitting posture and head posture, which helps to ensure the accuracy and consistency of the evaluation results, thereby more effectively guiding the user to adjust the sitting posture and head posture. By setting the preset range values ​​including the spacing deviation range value of 30cm±10cm, the head-down deviation range value of 25±10°, and the head-tilting deviation range value of 10±10°, the differences between individual users are taken into account, and the flexibility of the evaluation is ensured, so that the method of this case can enable the system to adapt to the sitting habits of different users, while still being able to accurately identify the sitting posture problems that need to be corrected. By limiting when the difference between the user's head posture and the standard value exceeds the preset range, or when abnormal behaviors such as frequent up and down changes occur, the processor chip can quickly identify and send a warning signal to the buzzer, so that when the user is distracted or sleepy, he can also be aware of his sitting posture or head posture problems, and take corresponding measures to adjust them.

[0067] As a preferred embodiment, the lens 3 changes the transparency of the lens 3 according to temperature changes / environmental changes. In this way, the lens can adapt to different temperature / environmental conditions, thereby flexibly changing the transparency, further improving the practicality and comfort of the glasses. For example, in a strong sunlight environment, the lens can automatically reduce the transparency to reduce the stimulation of light to the eyes; in a dim environment, the lens can increase the transparency to improve the clarity of the field of vision. This adaptive adjustment function not only helps to protect the user's vision health, but also improves the overall performance of the glasses and user experience.

[0068] In summary, the present invention relates to a kind of glasses for preventing and controlling myopia and correcting sitting posture and a control method thereof. The glasses integrate a distance sensor and a multi-axis sensor, and can monitor the user's eye distance and head position and posture in real time. When it is detected that the eye distance is too close or too far, and the sitting posture is incorrect, such as lowering the head or tilting the head, the processor chip will receive and process this information to determine whether the user's eye habits and sitting posture meet the health standards. In order to achieve intelligent guidance, the glasses change the clarity of the lenses by adjusting the backlight of the lenses, thereby intelligently guiding the wearer to adjust the eye distance and sitting posture. This adjustment method not only helps to cultivate correct eye posture and sitting habits, but also effectively reduces vision problems and spinal problems caused by bad posture. In addition, the present invention also blurs the lenses by adjusting the backlight of the lenses, so that the user can intuitively see that the line of sight is blocked, so as to immediately realize that the sitting posture is incorrect and actively adjust it. Compared with the vibration reminder, the backlight reminder method is gentler and will not interfere with the user's body or operation in a physical way.

[0069] As mentioned above, this case protects a pair of glasses for preventing and controlling myopia and correcting sitting posture and a control method thereof. All technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
