Technical Field

[0001] The present invention relates to the field of eye health care, and in particular to a posture correction method, system and terminal for preventing and controlling pseudomyopia in adolescents. Background Art

[0002] Nowadays, students are suffering from myopia at a younger age. The main reason for this phenomenon is that teenagers are burdened with increasing schoolwork and spend too much time studying every day. In addition, with the development of Internet technology, teenagers are becoming more and more addicted to online games. The above unscientific eye habits have caused the vision of teenagers to decline rapidly. The importance and urgency of preventing myopia have been increasingly put on the agenda. It is urgent to pay attention to the vision of teenagers. The decline of vision among teenagers has become a public health issue of common concern and urgent need to be solved all over the world.

[0003] In order to prevent myopia among teenagers, except for teenagers with strong self-awareness and self-discipline, most families currently supervise their children by their parents. When parents are around their children, they will correct their children's posture to help them develop good eye habits. This kind of personal supervision can only be done when parents are around their children. However, parents are not always around their children most of the time, and teenagers have poor self-awareness. When there is no supervision, good posture and good eye habits cannot be guaranteed, which makes supervision not very effective and the efficiency of supervision is low. Summary of the invention

[0004] In order to improve the efficiency of supervision on the prevention of pseudomyopia in adolescents and to cultivate good eye habits, the present invention provides a posture correction method, system and terminal for the prevention and control of pseudomyopia in adolescents.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The embodiment of the present application discloses a posture correction method for preventing and controlling pseudomyopia in adolescents. By wearing a wearable device on the body, the sensor on the wearable device can detect the body posture of the adolescent, determine whether the body posture meets the standard, and adjust the posture of the adolescent in various scenarios to prevent and control pseudomyopia in adolescents.

[0026] Reference Figure 1 A posture correction method for preventing and controlling pseudomyopia in adolescents comprises the following steps: Step S100: obtaining location information and image detection information of a preset positioning point on the wearable device.

[0027] The wearable device is worn by teenagers to correct their body posture. The wearable device has two shoulder straps and two connecting straps located on the front and back sides of the body for connecting the shoulder straps. Positioning points are set on the shoulder straps and the connecting straps, and the positioning points are angle sensors. The change in body posture can be determined based on the change in the distance between the two angle sensors.

[0028] The location information of the positioning points refers to the position distribution of the positioning points on the body when the wearable device is worn. The location information is mainly reflected by the distance relationship between the two positioning points, that is, the relative position of each positioning point on the body is determined by analyzing the angle sensors at each positioning point.

[0029] Image detection information refers to an image of the environment in front of the human body obtained by a micro camera set on the wearable device.

[0030] Step S101: matching the viewing type from a preset object feature database according to the image detection information, where the viewing type includes a paper type and an electronic type.

[0031] The object feature database is a database obtained through machine learning, which contains records of various objects that teenagers browse and watch when studying or relaxing, including paper books and electronic products. The viewing type is the object viewed by teenagers, among which the paper type includes books, and the electronic type includes electronic products such as mobile phones and tablets.

[0032] By using a micro camera to detect objects in front of a person, and then comparing the acquired objects with the data in the object feature database, the type of the object can be matched.

[0033] Step S102: Under the paper type, determine the body posture information according to the position information of each positioning point.

[0034] Body posture information refers to the body posture of the current person when reading. The position information of each positioning point on the wearable device is different under different postures and corresponds one to one. By analyzing the position information of the positioning point, the current body posture can be determined.

[0035] Step S103: When the body posture information does not fall within the preset standard posture range, the posture deviation amount is determined according to the body posture information and the standard posture range.

[0036] The standard posture range is a reference range set by technicians based on the good body posture of the general population. Activities such as learning and reading in this posture can prevent pseudomyopia, which will not be elaborated here.

[0037] Compare the person's current body posture information with the standard posture range. If the body posture information falls within the standard posture range, it means that the person's current body posture during learning is good and meets the standard requirements, and the wearable device only gives a prompt. If the body posture information does not fall within the standard posture range, it means that the person is not learning and reading with a good body posture. In this body posture, vision may be affected, so posture correction is required. The posture deviation is the amount of adjustment that the wearable device needs to make to the person's body posture. The posture deviation is the difference between the body posture information and the standard posture range.

[0038] Step S104: matching the correction force of the wearable device according to the posture deviation amount.

[0039] Correction force refers to the force applied by the wearable device to the person's body when correcting the person's body posture. The greater the posture deviation, the greater the force that needs to be applied, otherwise the spine cannot be completely corrected.

[0040] Step S105: Prompt based on the posture deviation amount and correction strength.

[0041] After the wearable device determines the amount of posture deviation and the correction force based on the person's body posture information, it will issue a voice prompt to warn the person that the body posture correction process will follow so that the person can be mentally prepared.

[0042] The method of body posture correction is to control the tightness of the shoulder straps of the wearable device so that the body posture of the person is passively adjusted. In this embodiment, the length of the shoulder straps of the wearable device can be adjusted by telescopic adjustment.

[0043] Reference Figure 2 , the posture correction method for adolescents when they are tired in the paper type includes the following steps: Step S200: Obtain the holding time of the paper type.

[0044] The holding time refers to the time that the person's body posture is maintained within the standard posture range during learning. After the person's body posture is adjusted to the standard posture range, the wearable device starts counting the holding time through the timer inside the system.

[0045] Step S2001: When the holding time is less than the preset fatigue time, continue to obtain the holding time.

[0046] The fatigue time is a reference value set by technicians based on the time required for the general population to maintain a fixed posture until fatigue occurs, and will not be elaborated here.

[0047] The hold time and fatigue time are compared. If the hold time does not reach the fatigue time, it is determined that the person's body posture can continue to be maintained within the standard posture range. At this time, the wearable device will not adjust the posture, but will continue to count the hold time.

[0048] Step S2002: When the holding time is not less than the preset fatigue time, the difference between the holding time and the fatigue time is determined, and the difference is defined as the excess time.

[0049] If the holding time exceeds the fatigue time, the system determines that the person is beginning to feel fatigued and needs to rest. The system will control the wearable device to relax the person. The adjustment amount of the wearable device is related to the amount by which the holding time exceeds the fatigue time, which will not be elaborated here.

[0050] The excess time is the amount by which the hold time exceeds the fatigue time. After the hold time exceeds the fatigue time, the wearable device will continue to obtain the hold time and adjust the wearable device according to the excess time.

[0051] Step S20021: adjusting the angle according to the exceeding time matching posture.

[0052] The posture adjustment angle refers to the angle that the wearable device allows the person's body to bend in order to eliminate fatigue. By allowing the person to bend and relax, fatigue can be reduced. The posture adjustment angle corresponds to the duration of the overtime. The longer the overtime, the larger the posture adjustment angle allowed, until the posture adjustment angle reaches the set maximum angle.

[0053] Step S20022: Prompt by adjusting the angle according to the posture.

[0054] The system gives real-time voice prompts based on changes in posture adjustment angles, notifying personnel of their current status and the status of the wearable device, and adjusts body posture by controlling the wearable device. Adjusting body posture includes the following steps: Step S200221, determining the extension of the shoulder strap of the wearable device according to the posture adjustment angle.

[0055] The wearable device adjusts and extends the shoulder straps so that the person's body can bend. The shoulder strap extension is the amount of adjustment of the shoulder straps by the wearable device.

[0056] The amount of shoulder strap extension is related to the posture adjustment angle and has a one-to-one correspondence. The larger the posture adjustment angle, the greater the amount of shoulder strap extension of the wearable device. Therefore, the amount of shoulder strap extension can be determined by the posture adjustment angle.

[0057] Step S200222, controlling the shoulder straps of the wearable device to extend according to the extension amount of the shoulder straps to adjust the posture.

[0058] The wearable device continuously obtains the holding time. As the holding time increases, the shoulder strap extension also increases. Therefore, the wearable device adjusts the personnel's posture in a continuous dynamic process. When the holding time exceeds the fatigue time, the wearable device begins to adjust.

[0059] Reference Figure 3 After the posture is adjusted according to the posture adjustment angle, a shadow will appear on the reading material. The method for removing the shadow includes the following steps: In this embodiment, the application scenario is that a teenager is sitting at a desk to study, and the lighting device illuminates the book. When the holding time exceeds the fatigue time, the wearable device will adjust the teenager's body posture to relax. At this time, the teenager's body will gradually lean forward and the distance from the book will gradually get closer. In order not to affect vision, the steps of this embodiment are performed simultaneously during the process of the wearable device adjusting the posture to relax.

[0060] Step S300: determining the shadow features and shadow feature range produced by the human body under a preset lighting device according to the image detection information and a preset shadow feature library.

[0061] The lighting device refers to the lamp used to illuminate the book, specifically a desk lamp.

[0062] The shadow feature library is a database containing shadow morphological images obtained by the system through machine learning, which will not be described in detail here.

[0063] By comparing the image detection information with the shadow feature library, the shadow features and shadow feature range in front of the person can be identified. The shadow feature range is the range covered by the shadow on the desktop or reading material.

[0064] Step S301: matching the reading object position and reading object range from a preset reading object feature database according to the image detection information.

[0065] The reading material feature database is a database containing image features of various reading material forms, which is stored in the system and will not be described in detail here.

[0066] The image detection information in front of the person is obtained through a micro camera, and then the obtained image detection information is matched with the reading feature database to determine whether there is a reading feature in front of the person and determine the location of the reading feature and the reading range by performing image recognition processing on the image detection information. The reading range refers to the range covered by the reading on the desktop.

[0067] Step S302: when the reading object range falls within the shadow feature range, the illumination power and illumination angle of the illumination device are determined according to the illumination device parameter determination method.

[0068] When the reading object range does not fall into the shadow feature range, the reading object position is well illuminated and will not affect the reading of personnel and the eyes. In this case, no system intervention is required.

[0069] When the reading material range falls into the shadow characteristic range, part of the shadow produced by the person's body under the light may cover the reading material, resulting in a shadow on the reading material. At this time, the illumination power and illumination angle of the lighting device need to be adjusted.

[0070] The irradiation power is the luminous power of the lighting device. The greater the luminous power, the greater the light intensity.

[0071] The angle of illumination refers to the direction of light emitted by a lighting device.

[0072] The two parameters of the illumination power and illumination angle of the illumination device are determined by a method for determining the parameters of the illumination device. The method for determining the parameters of the illumination device is not described in detail here, but will be described in detail in subsequent embodiments.

[0073] Step S303: controlling the lighting device to perform lighting according to the lighting power and the lighting angle.

[0074] After determining the two parameters of irradiation power and irradiation angle, the lighting device is adjusted so that the shadow cast by the person's body is removed from the reading material.

[0075] The method for determining lighting device parameters comprises the following steps: Step S400: Match the lighting device position from a preset lighting device feature database according to the image detection information, and determine the spacing distance value between the preset lighting device and the wearable device according to the lighting device position, the preset reference position and the reference coordinates of the reference position.

[0076] The lighting device database is a database obtained by machine learning, which includes desk lamps of various shapes and types, which will not be described here.

[0077] By acquiring image detection information in front of the person through a micro camera, and then matching the acquired image detection information with the lighting device database, it is possible to determine whether there is a lighting device in front of the person and determine the position of the lighting device in the image detection information. The lighting device position is the position of the lighting device in the image detection information.

[0078] The preset reference position and the reference coordinates of the reference position are reference targets set by technicians for determining the actual position of the lighting device, and are not described in detail here. The reference position selects a fixed object on the desk as a reference.

[0079] By analyzing the reference position of the image detection information and the reference coordinates of the actual reference position, the scaling ratio of the image detection information can be determined, and then the actual spacing distance value between the lighting device and the wearable device can be determined by combining the scaling ratio and the position of the lighting device in the image detection information for analysis.

[0080] Step S401: determining an irradiation distance value according to a spacing distance value, a preset reference reading distance value, and a preset reference irradiation angle.

[0081] The preset benchmark reading distance value is the standard distance value between the wearable device and the book when the teenager's body posture is in the standard posture range, which is set by the technician and can be identified as the distance between the person and the book, and will not be elaborated here.

[0082] The reference illumination angle is the initial illumination angle of the lighting device, which can be determined as the angle between the reference reading distance value and the spacing distance value. When the teenager's body posture is in the standard posture range and the lighting device illuminates at the reference illumination angle, no human shadow will appear on the book.

[0083] The irradiation distance value is the distance between the lighting device and the book, and the irradiation distance value can be calculated according to the cosine formula through the spacing distance value, the reference reading distance value and the reference irradiation angle.

[0084] Step S402: Analyze and match the illumination power according to the illumination distance value and the preset reading illumination intensity.

[0085] The preset reading light intensity is a light intensity range in which the light reflected from the book is not likely to affect the eyes when teenagers read, and will not be elaborated here.

[0086] The irradiation power is determined by the irradiation distance value and the reading light intensity. The reading light intensity is a fixed reference value. The larger the irradiation distance value, the greater the irradiation power.

[0087] Step S403: determining a learning distance value between the reading object and the wearable device according to the reading object position, a preset reference position, and a reference coordinate of the reference position.

[0088] The learning distance value is the distance between the wearable device and the book. When the wearable device adjusts the body posture of the person, the distance between the wearable device and the book will also change, so it is necessary to obtain the learning distance value. The method for obtaining the learning distance value is the same as the method for obtaining the spacing distance value in step S400, and will not be repeated here.

[0089] Step S404: determining whether to issue a prompt based on a comparison between the learned distance value and a preset warning distance value or determining an irradiation angle based on the learned distance value and the irradiation distance value.

[0090] The warning distance value is a reference value set by the technician to prevent the distance between the person and the book from being too close, so it will not be elaborated here. During the process of the wearable device adjusting the person's body posture and relaxing it, if the learning distance value is not less than the warning distance value, it means that the distance between the person and the book meets the requirements, and only a prompt will appear to remind the person that the distance between the person and the book is shrinking. If the learning distance value is less than the warning distance value, it means that the distance between the person and the book is too small, and the person's shadow under the light will appear on the book, affecting the eyes when reading. At this time, the illumination angle of the lighting device needs to be adjusted. The illumination angle is recalculated and determined based on the learning distance value and the illumination distance value.

[0091] Step S405: outputting the irradiation power and irradiation angle.

[0092] After determining the two parameters of irradiation power and irradiation angle, the system outputs the two parameters to the lighting device, and the lighting device is adjusted according to the two parameters.

[0093] Reference Figure 4 , the method for handling reading materials under sunlight includes the following steps: The environment of this embodiment is: teenagers are reading at a desk, and sunlight shines through the window to increase the indoor brightness. At this time, there is no need to turn on the lights.

[0094] Step S500: Acquire the ambient light intensity at the reading object location.

[0095] Ambient light intensity refers to the brightness at the reading position under sunlight, and the ambient light intensity is acquired by a photosensitive element set on the wearable device.

[0096] Step S5001: When the ambient light intensity falls within the preset reference adaptation light range, continue to detect the ambient light intensity.

[0097] The benchmark adaptation lighting range is the range of light brightness that the eyes of teenagers can adapt to without easily getting tired or damaged when learning to read. The benchmark adaptation lighting range is set by technical personnel and will not be elaborated here.

[0098] When the ambient light intensity falls within the reference adaptation light range, it means that the light intensity at the reading position is not large, and it is not easy to cause damage to the eyes when reading. At this time, the system will not intervene, but will always detect the ambient light intensity.

[0099] Step S5002: When the ambient light intensity exceeds the reference adaptive light range, a prompt is given.

[0100] When the ambient light intensity exceeds the reference adaptive light range, it means that the light intensity at the reading position is too high. At this time, directly looking at the reading material will affect the eyes due to the light reflected on it. The system will give a voice prompt to inform that the light is strong at this time, and automatically control the shading device to cover the reading position to adjust the light.

[0101] In this implementation, the illumination adjustment method is: Step S50021, obtaining the horizontal distance between the reading object position and the window and the local time information.

[0102] The method for obtaining the horizontal distance between the reading object position and the window is the same as the method for obtaining the spacing distance value in step S400, and will not be described in detail here.

[0103] Local time information refers to the current time point when teenagers are learning to read. The system of the wearable device can automatically obtain the time from the network.

[0104] Step S50022, matching the solar altitude angle from a preset solar altitude angle database according to the local time information.

[0105] The solar altitude angle database is a database formed by recording the solar altitude angle data at various time points throughout the year through big data. The solar altitude angle here refers to the angle of illumination. The solar altitude angle is matched from the solar altitude angle database through local time information.

[0106] Step S50023, determining the shielding position of the sunshade device preset on the window according to the position of the reading object, the horizontal distance and the solar altitude angle.

[0107] The shielding position refers to the shielding position of the sunshade on the window. In the present embodiment, the sunshade is arranged on the top of the window when not in use, and when shading is needed, the sunshade is lowered to the shielding position by the hanging rope according to the shielding position.

[0108] The shielding position can be calculated using the tangent formula through the reading object position, horizontal distance and solar altitude angle.

[0109] Step S50024, controlling the sunshade device to adjust its position on the window according to the shielding position to shield the light at the reading position, and determining the shadow light increase amount according to the ambient light intensity and the reference adaptive light range.

[0110] When a shadow is created on a book by the sunshade device, the brightness in the shadow may be low. In this case, it is necessary to check again whether the ambient light intensity meets the requirements.

[0111] If the ambient light intensity falls within the reference adaptation light range, it meets the requirements. Otherwise, it is necessary to increase the light intensity.

[0112] The shadow light gain is the light intensity that needs to be increased at the shadow position on the book to meet the requirements of eye protection. The shadow light gain is the difference between the ambient light intensity and the benchmark adaptation light range.

[0113] Step S50025, matching the light transmittance of the sunshade device according to the shadow light increase amount, and controlling the sunshade device to adjust the light transmittance according to the light transmittance.

[0114] The material of the sunshade device itself has a certain light transmission ability, and the sunshade device is a structure of a blind. By opening and closing the sunshade device, the light transmittance can be adjusted. The light transmittance corresponds to the amount of shadow light increase. The greater the amount of shadow light increase, the higher the light transmittance needs to be.

[0115] After determining the light transmittance, the sunshade device is opened and closed, and the brightness of the shadow position on the book can be increased.

[0116] Reference Figure 5 , a method for processing shadows appearing on book pages when flipping through a reading material includes the following steps: The scenario targeted by this embodiment is: when reading a paper book, a shadow may be produced on the book due to the obstruction of the paper itself.

[0117] Step S600: when flipping through the reading material, determining the reading page range according to the position of the reading material, and obtaining the text range, the page shadow range, and the color difference value between the text and the background within the reading page range.

[0118] The reading page range refers to the range of paper on a book for people to read. The reading page range can be identified by a micro camera at the position of the reading object. This is existing technology and will not be described in detail here.

[0119] The text range is the range of text or images printed on the paper. The shadow range of the book page refers to the range of shadows caused by the book page itself. The color difference value is the color difference between the text and image on the paper and the paper background, which is mainly the grayscale difference. The identification methods of the text range, book page shadow range and color difference value are the same as those of the reading page range, so they will not be repeated here.

[0120] Step S601: Determine whether the shadow range of the book page falls within the text range.

[0121] By judging the overlap between the shadow range of the book page and the text range, it is determined whether the shadow covers the text, so that the brightness is reduced when teenagers read the text.

[0122] Step S602: If and only if it falls into the range, control the preset auxiliary lighting device to illuminate the reading page range.

[0123] The auxiliary lighting device is used for providing auxiliary lighting to books when teenagers are reading so as to increase the brightness on the books.

[0124] If the shadow range of the book page does not fall into the text range, no intervention is required. However, when the shadow range of the book page falls into the text range, the text range needs to be illuminated by an auxiliary lighting device.

[0125] Step S603: Under the illumination of the auxiliary illumination device, determine whether the color difference value within the reading page range falls within a preset identification color difference range.

[0126] Under the illumination of an auxiliary lighting device, the color difference between text and background may be smaller, making it difficult for the human eye to distinguish between text and background. Forcing the eyes to read will accelerate eye fatigue. Therefore, it is necessary to judge the color difference value within the reading page range under the illumination of an auxiliary lighting device.

[0127] The recognition color difference range refers to the color difference range of two objects that can be easily recognized by the eyes. The recognition color difference range is a reference value set by the technicians and will not be elaborated here.

[0128] When the color difference value within the reading page range does not fall within the recognition color difference range, the color difference value within the reading page range needs to be adjusted.

[0129] Step S604: if and only if it does not fall within the range, determine the color temperature adjustment value of the auxiliary lighting device according to the color difference value and the identified color difference range, and control the auxiliary lighting device to adjust the color temperature according to the color temperature adjustment value.

[0130] The color temperature of the auxiliary lighting device is adjusted to adjust the color difference value within the reading page range. The color temperature adjustment value is the amount by which the auxiliary lighting device adjusts the color temperature according to the color difference value. The color temperature adjustment value corresponds to the color difference value one by one, and the color temperature adjustment value can be determined according to the color difference value.

[0131] Reference Figure 6 When the posture adjustment angle reaches the preset maximum angle, the processing method includes the following steps: In this embodiment, when the holding time exceeds the fatigue time, the posture adjustment angle reaches the preset maximum angle, and the shoulder strap extension reaches the preset maximum extension, the wearable device will use another method to adjust the posture and relax. The preset maximum extension is a reference value set by the technician and will not be described here. The shoulder strap cannot be extended infinitely. When the shoulder strap length reaches the maximum extension, the distance between the teenager and the book will be too close, which will affect the vision. Therefore, when the shoulder strap reaches the maximum extension, the shoulder strap will no longer continue to extend, and acupoint massage will be used to relax. The wearable device is equipped with a massage device on the connecting belt on the back, which can massage the acupoints.

[0132] First, the length of the shoulder strap of the wearable device is reset, with the aim of resetting the connecting belt to the initial position, that is, the position when the body posture is in the standard posture range, so as to facilitate the precise positioning of the acupoints.

[0133] Step S700: When the posture adjustment angle reaches a preset maximum angle, the wearable device gives a prompt.

[0134] The system makes a judgment based on the size of the posture adjustment angle. When the posture adjustment angle reaches the preset maximum angle, the wearable device will issue a prompt to alert the person that another massage method will be used next. After the prompt is completed, the massage adjustment will be carried out.

[0135] Step S701: determining the adjustment distance according to the preset starting point position of the massage device on the wearable device and the preset eye-improving acupuncture point position.

[0136] The starting position of the massage device is the position of the massage device on the connecting belt when the body posture of the person is in the standard posture range. When the person wears the wearable device and the body posture is in the standard posture range, the position of the connecting belt is fixed.

[0137] The eye-brightening acupoint position refers to an acupoint in traditional Chinese medicine on the back of the human body, which is a fixed position on the back of the human body. The eye-brightening acupoint position is the position where the massage device massages. Massaging this acupoint can improve eyesight, and massage can also relax the body. In this embodiment, the eye-brightening acupoint specifically refers to the liver point.

[0138] The adjustment distance refers to the distance required to adjust the massage device on the connecting belt from the starting position to the eye-improving acupuncture point position. Since both are fixed points, the adjustment distance can be determined based on the positions of the two points.

[0139] Step S702: Control the massage device to move from the starting position to the eye-improving acupuncture point position according to the adjusted distance.

[0140] In this embodiment, the massage device is moved by controlling the length of the shoulder strap. The shoulder strap adjustment length corresponds to the adjustment distance, and the shoulder strap adjustment length can be calculated by the adjustment distance.

[0141] After the shoulder strap adjustment length is determined, the massage device is moved to the eye-improving acupuncture point position by controlling the length of the shoulder strap.

[0142] Step S703: matching an effective massage range from a preset acupoint model according to the location of the eye-improving acupoint.

[0143] The acupoint model is a standard model set by technicians, which records the location of acupoints on the human body and the effective massage range for specific acupoints. The effective massage range refers to the range of position that can produce a specific effect when massaging an acupoint.

[0144] The massage device performs massage within the effective massage range, which can effectively improve eyesight.

[0145] Step S704: Control the massage device to perform massage within an effective massage range according to the preset vibration frequency and the preset heating temperature.

[0146] The preset vibration frequency and the preset heating temperature are parameters of the massage device for massaging the eye-improving acupoints, which are reference values ​​set by technicians and will not be described in detail here. By massaging the acupoints with the preset vibration frequency and the preset heating temperature, the acupoints can play an effective role.

[0147] In this embodiment, the massage device massages the acupuncture points driven by the shoulder straps, and the shoulder straps can also perform reciprocating telescopic motions, which can drive the whole body to perform relaxation exercises and reduce fatigue. The specific method is: Step S7041, determining the reciprocating adjustment amount of the shoulder strap according to the effective massage range, and controlling the shoulder strap to reciprocate and retract according to the reciprocating adjustment amount.

[0148] The massage device is moved within the effective massage range by reciprocatingly adjusting the length of the shoulder strap. The reciprocating adjustment amount refers to the adjustment amount of the shoulder strap length, that is, the adjustment amount required for the shoulder strap length to enable the massage device to move within the effective massage range.

[0149] The effective massage range is a circular area, and the reciprocating adjustment amount of the shoulder strap is the radius distance of the effective massage range.

[0150] The posture correction method for teenagers when their viewing type is electronic includes the following steps: In this embodiment, the bad posture of teenagers reading while lying on their side is corrected.

[0151] Step S800: Obtain the pressure difference between the two sides of the wearable device.

[0152] When a person lies on his side, the pressures on the shoulder straps on both sides of the wearable device are different. The pressure difference between the shoulder straps on both sides can be obtained and analyzed by the pressure sensors set on the shoulder straps.

[0153] Step S801: determining the viewing posture type according to the comparison relationship between the pressure difference and the preset allowable pressure difference, where the viewing posture types include side-lying posture and normal posture.

[0154] When a person wears the wearable device, there may be a pressure difference between the shoulder straps on both sides due to the tilt of the wearable device. The allowable pressure difference is the reference value of the error range set by the technicians for the above situation, which will not be elaborated here.

[0155] When the pressure difference is within the allowable range, there is almost no pressure difference between the shoulder straps on both sides, indicating that the teenager's body posture is good and in a normal posture. When the pressure difference exceeds the allowable range, the teenager may be in a side-lying posture, and the pressure difference between the shoulder straps on both sides is large.

[0156] Step S802: When in the side-lying posture, determine the side-lying direction according to the positive or negative situation of the pressure difference.

[0157] When the body posture is in the standard posture range, the pressure on the shoulder strap is relatively small. When a person lies on his side, the pressure on the shoulder strap on the side lying on will increase. Therefore, the side-lying direction can be determined based on the comparison of the pressure on the shoulder straps on both sides.

[0158] Step S803: Prompt according to the side-lying direction.

[0159] After determining the side-lying direction of the person, the system will send a prompt through the wearable device to inform the person that the device will correct the person's posture next. The specific method of side-lying posture correction is: Step S8031, matching the shoulder strap of the corresponding side according to the side-lying direction and defining it as an adjustable shoulder strap, and issuing a prompt for adjusting the shoulder strap.

[0160] After the side-lying direction is determined, the shoulder strap on the opposite side of the side-lying direction is set as the shoulder strap that needs to be adjusted, and a prompt will be issued on the shoulder strap to remind the person that the shoulder strap is about to be adjusted.

[0161] Step S8032, controlling and adjusting the shoulder straps to retract according to the preset warning retraction amount.

[0162] The warning contraction amount is a reference value set by the technician for adjusting the shoulder straps. By forcibly adjusting the shoulder straps on the opposite side of the side-lying direction, the person can forcibly adjust from the side-lying posture back to the normal posture.

[0163] Step S8033: When and only when the viewing posture type is in the normal posture, control the shoulder strap to be adjusted to reset.

[0164] When the body posture of the person returns to a normal posture, the shoulder strap is controlled and adjusted to return to an initial normal state.

[0165] The calculation formula for the shoulder strap extension of the wearable device at different times under the paper type is: ; in, is the maximum angle for adjusting the posture of the wearable device, t is the holding time, t0 is the fatigue time, t max is the maximum holding time, K is the proportional coefficient, D1 and D2 are the positioning points of the back of the wearable device on the shoulder straps on both sides, and D3 is the positioning point of the front of the wearable device on the chest.

[0166] When a person is reading a book, if the holding time exceeds the fatigue time, the wearable device adjusts the shoulder strap to adjust the person's body posture, and the shoulder strap extension is calculated by the above formula. When the holding time t is not greater than the fatigue time t0, the shoulder strap extension L=0; when the holding time t is greater than the fatigue time t0, the shoulder strap extension L is equal to ,t,t0,t max , K, D1, D2, D3 and other parameters are related.

[0167] The wearable device is also equipped with a vibration sensor on the connecting belt on the front side of the body. The vibration sensor is used to obtain chest frequency information. Chest frequency information refers to the frequency of chest fluctuations when a person breathes. According to the chest frequency information, the detection state is matched from the preset frequency database. The detection state includes active state and sleep state.

[0168] If the frequency of chest vibration of a person is slow, that is, the person is in a sleeping state, the wearable device will not correct the person's posture. Only when the frequency of chest vibration of a person is high, that is, the person is in an active state, the wearable device will correct the person's posture.

[0169] In an active state, the posture correction method in a vibrating environment includes the following steps: In this embodiment, the situation targeted is: teenagers are reading on a moving vehicle or while walking.

[0170] Step S900: Obtain vibration information of a positioning point on the wearable device.

[0171] Vibration information refers to the vibrations received by various positioning points on a wearable device when a person is in a vibrating environment. The vibration information of the positioning points is obtained through vibration sensors installed at the positioning points.

[0172] Step S901: matching the environmental vibration from a preset environmental vibration database according to the vibration information.

[0173] The environmental vibration database is a database set by technicians according to various vibration conditions, which will not be described in detail here. According to the vibration information, it can be determined from the environmental vibration database whether the current teenager is in a vibrating environment.

[0174] Step S902: Under environmental vibration, judging whether there is a reading object feature from a preset reading object feature database according to image detection information.

[0175] The reading material feature database is a database containing information of various reading materials obtained through machine learning, which will not be elaborated here.

[0176] When the wearable device detects that the teenager is in a vibrating environment, it will use a micro camera to capture an image in front of the person and use the image detection information to determine whether the teenager is reading a book or playing with a mobile phone in the vibrating environment. If the above situation occurs, the wearable device will perform posture correction.

[0177] Step S903: If and only if there is a reading feature, record the reading time value.

[0178] The reading time value refers to the length of time teenagers spend reading. The wearable device uses a built-in timer in the system to count the time, and records the reading time value from the moment the reading material is detected.

[0179] Step S904: Determine whether the reading time value exceeds the preset visual fatigue duration.

[0180] The visual fatigue duration is the length of time set by the technicians when a person will experience visual fatigue when reading materials in a vibrating environment, and will not be elaborated here.

[0181] The reading time value is within the visual fatigue duration, and the wearable device operator browses reading materials. At this time, teenagers may just check messages on their mobile phones.

[0182] When the reading time value exceeds the visual fatigue duration, the wearable device needs to intervene to prevent teenagers from continuing to browse reading materials.

[0183] Step S905: If and only if it exceeds the limit, control the wearable device to issue a prompt, control the wearable device to perform correction according to the standard posture range, and obtain the mandibular distance between the wearable device and the preset human mandibular distance.

[0184] When the reading time exceeds the visual fatigue time, the wearable device will first issue a prompt to remind the teenager that the wearable device is about to adjust the posture. After the prompt is completed, the wearable device will adjust the person's body posture to the standard posture range. In the standard posture range, it is inconvenient for teenagers to read unless they lower their heads, so the teenager's head-lowering action is detected.

[0185] The mandibular distance refers to the distance between the wearable device and the human mandible, which is obtained by a rangefinder set at the positioning point on the front side of the wearable device.

[0186] Step S906: When and only when the mandibular distance is not greater than the preset reference level viewing distance, control the wearable device to give a prompt.

[0187] The reference eye level distance is the distance between the wearable device and the jaw when the person is looking straight ahead, which is a reference value set by the technician. When the jaw distance is not greater than the reference eye level distance, the wearable device will continue to remind the teenager.
