Description

Technical Field

[0001] This invention relates to the technical field of health management of screen terminals, and more specifically, to a method and system for managing the use of screen terminals. Background Technology

[0002] With the widespread adoption of digital education, children are increasingly participating in online learning, early programming, and digital reading through electronic screens. However, children generally lack self-discipline and frequently exhibit unhealthy behaviors such as close-range eye use, hunching over, tilting their heads forward, and looking sideways while using screens. These habits directly contribute to the increasing incidence of myopia year by year, and skeletal health problems such as scoliosis are showing a clear trend of occurring at younger ages.

[0003] The existing methods for managing the healthy use of screen terminals in the market can be mainly divided into two categories: one is software-level intervention measures, such as adjusting the screen color temperature to reduce blue light radiation and setting timed pop-up reminders to force users to rest; the other is hardware-level additional devices, such as integrating a distance sensor into the screen bezel to trigger an audio alarm or display a warning icon when a user is detected approaching. However, the above solutions still have the following shortcomings: relying solely on passive reminders or warnings makes it easy for child users to habitually ignore them, resulting in insufficient control. Summary of the Invention

[0004] This invention provides a method for controlling the use of screen terminals, which solves the technical problem that existing technologies only use passive reminders or warnings, which can easily lead to child users habitually ignoring them, resulting in insufficient control.

[0005] This invention provides a method for controlling the use of a screen terminal, applied to a screen terminal control system. The screen terminal control system includes a multi-degree-of-freedom robotic arm and a screen terminal, with the screen terminal located at the end of the multi-degree-of-freedom robotic arm. The control method includes the following steps: Scene recognition step: Identify whether the current user's usage scenario is a child's usage scenario. If so, proceed with the health status collection step. Health status collection step: Collect the current user's health status data, wherein the health status data includes at least one dimension of eye distance data, sitting posture deviation data, continuous eye use duration data, and ambient light data; Health status assessment step: The collected health status data of at least one dimension is compared with the preset safety range of the corresponding dimension. If the status level of the health status data of at least one dimension is abnormal, the control step is executed. Control step: includes screen motion step, which is to control the multi-degree-of-freedom robotic arm to drive the screen terminal to adjust its posture in space, so as to actively change the physical interaction relationship between the current user and the screen terminal.

[0006] Optionally, the control step may further include a prompting step and / or a restriction step, wherein the prompting step provides prompts through at least one of voice prompts, screen image prompts, and indicator light prompts; and the restriction step restricts screen interaction functions and reduces screen brightness through at least one of these methods.

[0007] Optionally, if the status level of at least one dimension of the health status data is an abnormal state, the step of performing the control step includes: If the status level of the health status data in only one dimension is abnormal, then the control step corresponding to that single dimension is executed. If the status levels of the health status data in at least two dimensions are all abnormal, then the health status data in the at least two dimensions that are in an abnormal state are sorted based on the health risk priority of the health status data in the at least two dimensions; it is determined whether there is a conflict between the control steps corresponding to the at least two dimensions that are in an abnormal state. If not, the control steps corresponding to the dimension with higher health risk priority are executed at the same time as or after the control steps corresponding to the dimension with lower health risk priority are executed; if so, the screen motion steps corresponding to the dimension with higher health risk priority and the prompt steps corresponding to the dimension with lower health risk priority are executed.

[0008] Optionally, the health status data may include eye distance; The health status collection steps include: collecting the current user's eye distance data; The health status judgment step includes: comparing the collected current user's eye distance data with a preset safe distance threshold; if the current user's eye distance data is less than the preset safe distance threshold, the status level of the current user's eye distance data is an abnormal state, and the corresponding control step is executed.

[0009] Optionally, after the step of determining if the current user's viewing distance data is less than the preset safe distance threshold, the health status determination step further includes: Calculate the distance deviation between the lower limit of the preset safe distance threshold and the current user's eye distance data; Determine the magnitude relationship between the distance deviation and the first preset distance deviation, the second preset distance deviation, and the third preset distance deviation; If the distance deviation is less than the first preset distance deviation, a prompting step is executed, wherein the prompting step is performed by at least one of the following methods: voice prompt, screen image prompt, and indicator light prompt. If the distance deviation is greater than or equal to the first preset distance deviation and less than the second preset distance deviation, then a second control step is executed. The second control step includes a second screen movement step and a prompting step. The second screen movement step is to drive the screen terminal to move backward relative to the current user in space to within the preset safe distance threshold. The prompting step is to provide a prompt through at least one of the following methods: voice prompt, screen image prompt, and indicator light prompt. If the distance deviation is greater than or equal to the second preset distance deviation and less than the third preset distance deviation, then a third control step is executed. The third control step includes a third screen movement step and a restriction step. The third screen movement step is to drive the screen terminal to move backward relative to the current user in space to within the safe distance threshold. The restriction step is to restrict the screen by limiting screen interaction functions and reducing screen brightness. Wherein, the first preset distance deviation < the second preset distance deviation < the third preset distance deviation.

[0010] Optionally, if the health status data includes sitting posture deviation data; the sitting posture deviation type corresponding to the sitting posture deviation data includes at least one of hunchback, forward head posture, scoliosis, and head tilt. The health status collection step includes: collecting the current user's sitting posture deviation data and the duration of the sitting posture deviation; wherein, the sitting posture deviation data includes spinal tilt angle data and head tilt angle data, the spinal tilt angle data includes sagittal forward tilt angle and coronal lateral tilt angle, the sagittal forward tilt angle is used to determine hunchback, and the coronal lateral tilt angle is used to determine spinal tilt; the head tilt angle data includes sagittal cervical anteversion angle, coronal lateral flexion angle and horizontal torsion angle, the sagittal cervical anteversion angle is used to determine head forward tilt, and the coronal lateral flexion angle and the horizontal torsion angle are used to determine head tilt; The health status judgment step includes: comparing the collected current user's posture deviation data with the corresponding preset posture angle threshold and comparing the collected current user's posture deviation duration with a preset duration. If the current user's posture deviation data is greater than the preset posture angle threshold and the posture deviation duration is greater than or equal to the preset duration, then the status level of the current user's posture deviation data is an abnormal state, and the corresponding control step is executed.

[0011] Optionally, the types of posture deviations have a posture risk priority; Following the step of determining that the status level of the current user's posture deviation data is abnormal if the current user's posture deviation data is greater than the preset posture angle threshold and the posture deviation duration is greater than or equal to the preset duration, the health judgment step further includes: Based on the sitting posture deviation data in an abnormal state, determine the type of sitting posture deviation in an abnormal state; Based on the type of posture deviation that is in an abnormal state, the corresponding control step is executed, the control step including: If only the sagittal cervical tilt angle is greater than the corresponding preset sitting posture angle threshold, then the head is determined to be tilted forward, and the fourth control step is executed. The fourth control step includes a fourth screen movement step and a prompting step. The fourth screen movement step is to drive the screen terminal to move backward relative to the current user in space. The prompting step is to prompt the sitting posture adjustment through at least one of the following methods: voice prompt, screen image prompt, and indicator light prompt. If only the coronal plane lateral deviation angle is greater than the corresponding preset sitting posture angle threshold, then spinal tilt is determined and the fifth control step is executed. The fifth control step includes the fifth screen motion step, which is to drive the screen terminal to rotate relative to the current user in space to match the viewing angle. If only the coronal lateral flexion angle and the horizontal torsion angle are greater than the corresponding preset sitting posture angle threshold, then it is determined that the head is tilted and the sixth control step is executed. The sixth control step includes the sixth screen motion step, which is to drive the screen terminal to rotate relative to the current user in space to match the viewing angle. If only the sagittal anterior tilt angle is greater than the corresponding preset sitting posture angle threshold, it is determined to be hunchback and the seventh control step is executed. The seventh control step includes a seventh screen movement step and a prompting step. The seventh screen movement step is to move the screen terminal upward relative to the current user in space. The prompting step is to prompt the user to adjust their sitting posture through at least one of the following methods: voice prompt, screen image prompt, and indicator light prompt.

[0012] Optionally, the health status data may include data on continuous screen time. The health status collection steps include: collecting data on the current user's continuous screen time; The health status judgment step includes: comparing the collected continuous eye use duration data of the current user with the preset eye use duration; if the continuous eye use duration data of the current user is greater than or equal to the preset eye use duration, the status level of the continuous eye use duration data of the current user is an abnormal state, and the corresponding control step is executed.

[0013] Optionally, the preset eye use duration includes a first preset eye use duration, a second preset eye use duration, and a third preset eye use duration, wherein the first preset eye use duration < the second preset eye use duration < the third preset eye use duration; If the current user's continuous screen time duration is greater than or equal to the preset screen time duration, then the status level of the current user's continuous screen time duration is an abnormal state, and the corresponding control step is executed. Determine the relationship between the continuous eye use duration data and the first preset eye use duration, the second preset eye use duration, and the third preset eye use duration; If the continuous screen time data is greater than or equal to the third preset screen time, then the eighth control step is executed. The eighth control step includes a seventh screen motion step and a restriction step. The seventh screen motion step is to drive the screen terminal to move backward relative to the current user in space to a preset safe distance threshold. The restriction step is to restrict the screen by limiting screen interaction functions and reducing screen brightness. If the continuous eye use duration data is greater than or equal to the second preset eye use duration and less than the third preset eye use duration, then an eye relaxation step is executed, wherein the eye relaxation step is to control the screen to display preset eye-care relaxation content; If the screen time data is greater than or equal to the first preset screen time and less than the second preset screen time, then a rest suggestion step is executed, which involves controlling the screen to display a rest suggestion prompt.

[0014] The method for managing the use of a screen terminal provided by this invention has at least the following beneficial technical effects: By introducing a multi-degree-of-freedom robotic arm to drive the screen terminal for posture adjustment, and combining scene recognition, multi-dimensional health status data collection and judgment, proactive management of children's multi-dimensional health status is achieved. This fundamentally changes the current physical interaction between users and screen terminals, making it less likely for children to habitually ignore the screen, thus improving their proactive management capabilities and providing a healthier and safer screen-use environment for children, which helps reduce myopia rates and improve poor posture. In addition, by first identifying the child's usage scenario and then collecting, judging and managing their health status, differentiated management of usage scenarios is achieved, avoiding interference with non-learning scenarios.

[0015] The present invention also provides a screen terminal usage management system, characterized in that it is applied to the management method described above, and the management system includes: The scene recognition module is used to identify whether the current user's usage scenario is a child's usage scenario; The health status collection module is used to collect the health status data of the current user if the current user's usage scenario is a child's usage scenario.

The health status judgment module is used to compare the collected health status data of at least one dimension with the corresponding preset safety range of the dimension, and determine whether the status level of the health status data of at least one dimension is abnormal. If so, a control step is executed; and, The control module includes a screen motion module, which controls the multi-degree-of-freedom robotic arm to drive the screen terminal to adjust its posture in space, so as to actively change the physical interaction relationship between the current user and the screen terminal.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figures 1-7 Specific embodiments of the present invention will be described in detail below.

[0020] This invention provides a method for managing the use of a screen terminal, applied to a screen terminal management system. (See attached document.) Figure 1 The screen terminal usage control system includes a multi-degree-of-freedom robotic arm 01 and a screen terminal 02. The multi-degree-of-freedom robotic arm 01 can be a robotic arm with at least three degrees of freedom, capable of adjusting the posture of the screen terminal 02 in space through joint movement. The screen terminal can be a tablet computer or other display. The screen terminal 02 is located at the end of the multi-degree-of-freedom robotic arm 01, which is mounted on a base 03, which can be placed on a table. See Appendix. Figure 2 The control method includes the following steps: S100, Scene Recognition Step: Identify whether the current user's usage scenario is a child's usage scenario. If so, proceed to S120, Health Status Collection Step; specifically, identify whether the current user's identity information is that of a child user and whether the currently running application type is a preset learning application type. The identity information includes at least one of facial feature information, voiceprint feature information, usage behavior pattern, and display terminal pairing information matching. If so, proceed to the health status collection step. S120, Health Status Collection Step: Collect the current user's health status data, which includes at least one dimension of eye distance data, posture deviation data, continuous eye use duration data, and ambient light data; wherein, eye distance data is the actual distance between the current user's eyes and the screen, and can be collected based on at least one of a visual sensor, an infrared ranging sensor, an ultrasonic ranging sensor, and a structured light sensor; posture deviation data includes at least one of spinal tilt angle data, head turning angle data, and shoulder height difference, and can be collected based on at least one of visual skeletal key point detection, depth image analysis, and a pressure distribution sensor installed in the seat; continuous eye use duration data is the cumulative usage time of the current user since the start of this child use scenario; ambient light data is the ambient illuminance of the space where the current user is located, and can be collected based on an ambient light sensor and / or the light sensing component built into the display terminal.

[0021] S140, Health Status Judgment Step: S142, compare the collected health status data of at least one dimension with the preset safety range of the corresponding dimension. S144, if the health status data of at least one dimension is in an abnormal state, then execute S160, Control Step; specifically, each dimension presets one or more thresholds. For example, if the viewing distance data is less than the preset safe distance threshold (e.g., 30 cm), it is judged as an abnormal state; if the sitting posture deviation data is greater than the preset sitting posture angle threshold and the sitting posture deviation duration is greater than or equal to the preset duration, it is judged as an abnormal state; if the continuous viewing time data is greater than the preset viewing time (e.g., 30 minutes), it is judged as an abnormal state; if the ambient light data does not fall within the preset brightness threshold, it is judged as an abnormal state. It should be noted that the preset safety range of the corresponding dimension can be adjusted according to at least one of the following: the current user's age, the current environmental conditions, and historical usage data. When the health status data of any dimension exceeds the corresponding preset safety range, the health status data of that dimension is in an abnormal state, and then the control step is executed.

[0022] S160, Control Steps: This includes screen motion steps. Screen motion steps involve controlling a multi-degree-of-freedom robotic arm to drive the screen terminal to adjust its posture in space, thereby actively changing the physical interaction between the current user and the screen terminal. For example, when the viewing distance data is too close and is judged as an abnormal state, the multi-degree-of-freedom robotic arm can be controlled to drive the screen terminal to move backward relative to the current user in space to within a preset safe distance threshold, thereby increasing the distance between the current user's eyes and the screen. When the posture deviation data is judged as an abnormal state, the multi-degree-of-freedom robotic arm can be controlled to drive the screen terminal to move upward, backward, or rotate relative to the current user in space, thereby guiding the user to adjust their posture.

[0023] Compared to the passive reminder methods in existing technologies, the screen terminal usage management method provided in this invention introduces a multi-degree-of-freedom robotic arm to drive the screen terminal to adjust its posture. Combined with scene recognition and multi-dimensional health status data collection and judgment, it achieves proactive management of children's multi-dimensional health status. This fundamentally changes the current physical interaction between the user and the screen terminal, making it less likely for children to habitually ignore the screen and improving their proactive management capabilities. This provides children with a healthier and safer screen usage environment, helping to reduce myopia rates and improve poor posture. Furthermore, by first identifying the child's usage scenario and then collecting, judging, and managing their health status, differentiated management of usage scenarios is achieved, avoiding interference with non-learning scenarios.

[0024] In this embodiment of the invention, S160, the control step further includes a prompting step, which can be implemented in a variety of ways, such as by at least one of voice prompts, screen image prompts, and indicator light prompts; wherein, the prompting step can provide users with intuitive warnings, enabling users to promptly perceive their own unhealthy eye use or sitting posture habits, so as to guide the current user to correct unhealthy eye use and / or sitting posture habits; And / or, S160, the control step further includes a restriction step, which can be implemented in various ways, such as restricting screen interaction functions and reducing screen brightness by at least one of these methods. When the current user fails to respond to prompts in a timely manner or their health status remains abnormal, the restriction step can perform stronger control, reducing or preventing the current user from continuing to be in an unhealthy eye-use state, thereby protecting the current user's eye and / or posture health. With this setup, in addition to using a multi-degree-of-freedom robotic arm to drive the screen terminal for posture adjustment, the introduction of prompting steps and / or restriction steps allows for the selection of different control methods based on the severity of the abnormal state or the current user's response to control measures. For example, a combination of screen movement steps and prompting steps, or a combination of screen movement steps and restriction steps, can enhance guidance for the current user to correct unhealthy eye and / or posture habits. Furthermore, different control methods can be executed sequentially, such as executing prompting steps first, then screen movement steps, and finally restriction steps, to form a gradient control, thereby improving the refinement and effectiveness of screen terminal usage control and comprehensively enhancing the current user's screen health.

[0025] In one embodiment of the present invention, see appendix. Figure 2 S144, if the health status data of at least one dimension is in an abnormal state, the steps for performing the control step include: S1441, if the status level of only one dimension of health status data (e.g., eye distance data) is abnormal, then execute the control step corresponding to the single dimension; for example, if only the eye distance is too close, that is, if only the status level of the eye distance data is abnormal, then execute the screen motion step corresponding to the eye distance data, and control the multi-degree-of-freedom robotic arm to drive the screen terminal to move backward relative to the current user in space to the preset safety data threshold.

[0026] In another embodiment of the present invention, see Appendix Figure 2 S144, if the health status data of at least one dimension is in an abnormal state, the steps for performing the control step include: S1442, If the status level of at least two dimensions of health status data is abnormal, S1443, then based on the health risk priority of the at least two dimensions of health status data, sort the at least two dimensions of health status data that are in an abnormal state; wherein, the health risk priority can be customized by the guardian, for example, the health risk priority satisfies: eye distance data > posture deviation data > continuous eye use duration data > ambient light data. S1444, determine whether there is a conflict between the control steps corresponding to at least two dimensions in an abnormal state; S1445, if no, that is, there is no conflict, execute the control steps corresponding to the dimension with lower health risk priority at the same time or after executing the control steps corresponding to the dimension with higher health risk priority; S1446, if yes, that is, there is a conflict, execute the screen motion steps corresponding to the dimension with higher health risk priority and execute the prompt steps corresponding to the dimension with lower health risk priority. Specifically, for example, if the two dimensions of an abnormal state are eye distance data and posture deviation data, and the state level of the eye distance data is an abnormal state, it is necessary to drive the screen terminal to move backward relative to the current user, while the state level of the posture deviation data is an abnormal state (e.g., hunching over), it is necessary to drive the screen terminal to move upward relative to the current user. This means that there is no conflict between the control of the two, so the screen movement step corresponding to the eye distance data dimension and the prompt step corresponding to the posture deviation data dimension are executed. As another example, if the two dimensions of an abnormal state are eye distance data and continuous eye use duration, and the state level of the eye distance data is an abnormal state, it is necessary to drive the screen terminal to move backward relative to the current user, while the state level of the continuous eye use duration data is an abnormal state, it is necessary to execute the rest suggestion step. This means that there is no conflict between the control steps of the two, so the rest suggestion step is executed at the same time as or after the screen movement step corresponding to the eye distance data dimension. This setup prioritizes abnormal states across multiple dimensions by introducing health risk priorities, and further determines whether there are conflicts in the control steps corresponding to these dimensions. Different control methods are then selected to address situations where multiple dimensions of a user's health status simultaneously become abnormal. Specifically, for example, if control steps do not conflict, they can be executed simultaneously or sequentially to ensure all abnormal states are effectively handled. Conversely, if control steps conflict, the screen movement steps corresponding to the dimension with higher health risk priority can be executed first, along with the prompting steps corresponding to the dimension with lower priority. This ensures effective control of the dimension with higher health risk priority while also addressing the prompts for the dimension with lower priority, avoiding mutual interference between control actions.

[0027] In this embodiment of the invention, see appendix. Figure 4If the health status data includes eye distance; S120, the health status acquisition step includes: S171, acquiring the current user's eye distance data; specifically, acquiring the current user's eye distance data through a sensor located on the screen terminal or a multi-degree-of-freedom robotic arm, for example, the sensor may include an infrared sensor, a depth camera, etc.

[0028] S140, the health status judgment step includes: S172, comparing the collected current user's eye distance data with a preset safe distance threshold; S173, if the current user's eye distance data is less than the preset safe distance threshold (for example, for children, the preset safe distance threshold is 30-40 cm), meaning the current user's eye distance is too close, then the status level of the current user's eye distance data is abnormal, and the corresponding control step is executed. This setting, by collecting eye distance data in real time and comparing it with the preset safe distance threshold, can promptly and accurately detect abnormal eye distance states of the current user. If an excessively close eye distance is detected, corresponding control steps are executed. For example, a multi-degree-of-freedom robotic arm can drive the screen terminal to move backward relative to the current user in space, actively increasing the physical distance between the current user and the screen terminal, thereby effectively correcting the user's poor eye habits and reducing the damage to vision caused by prolonged close-range eye use.

[0029] In this embodiment of the invention, see appendix. Figure 4 S173, after the step of determining the health status if the current user's viewing distance data is less than the preset safe distance threshold, the health status determination step further includes: S174, Calculate the distance deviation between the lower limit of the preset safe distance threshold and the current user's eye distance data; S175, determine the magnitude relationship between the distance deviation and the first preset distance deviation, the second preset distance deviation and the third preset distance deviation; S176, if the distance deviation is less than the first preset distance deviation, it means that the distance deviation is small, then the prompting step is executed. The prompting step is to provide a prompt through at least one of the following methods: voice prompt, screen image prompt, and indicator light prompt. S177, if the distance deviation is greater than or equal to the first preset distance deviation and less than the second preset distance deviation, it means that the distance deviation is moderate, then the second control step is executed. The second control step includes a second screen movement step and a prompting step. The second screen movement step is to drive the screen terminal to move backward relative to the current user in space to within a preset safe distance threshold. The prompting step is to provide a prompt through at least one of the following methods: voice prompt, screen image prompt, and indicator light prompt. S178, if the distance deviation is greater than or equal to the second preset distance deviation and less than the third preset distance deviation, it means that the distance deviation is large, then the third control step is executed. The third control step includes a third screen motion step and a restriction step. The third screen motion step is to drive the screen terminal to move backward relative to the current user in space to within the safe distance threshold. The restriction step is to restrict the screen by at least one of restricting the screen interaction function and reducing the screen brightness. The settings are as follows: First preset distance deviation < Second preset distance deviation < Third preset distance deviation. This configuration allows for tiered control of abnormal viewing distance data. Specifically, when the viewing distance deviation is small, only a prompt step is used to avoid affecting the user's experience with the screen terminal. When the viewing distance deviation is moderate, a second screen movement step is used to actively adjust the screen position to within the safe distance threshold, combined with a prompt step to guide the user to correct their behavior. When the viewing distance deviation is large, a third screen movement step is executed to actively adjust the screen position to within the safe distance threshold, combined with a restriction step to effectively prevent unhealthy eye-use behaviors. This configuration, based on the degree of viewing distance deviation, executes different control steps, thereby improving the intelligence and user-friendliness of the overall screen terminal usage control method.

[0030] In this embodiment of the invention, see appendix. Figure 5 If the health status data includes sitting posture deviation data; the sitting posture deviation types corresponding to the sitting posture deviation data include at least one of hunchback, forward head posture, scoliosis, and head tilt. S120, the health status collection step includes: S181, collecting the current user's sitting posture deviation data and sitting posture deviation duration; wherein, the sitting posture deviation data includes spinal tilt angle data and head tilt angle data, the spinal tilt angle data includes sagittal forward tilt angle and coronal lateral tilt angle, the sagittal forward tilt angle is used to determine hunchback, and the coronal lateral tilt angle is used to determine spinal tilt; the head tilt angle data includes sagittal cervical anteversion angle, coronal lateral flexion angle and horizontal torsion angle, the sagittal cervical anteversion angle is used to determine head forward tilt, and the coronal lateral flexion angle and horizontal torsion angle are used to determine head tilt; S140, the health status judgment step includes: S182, comparing the collected current user's posture deviation data with the corresponding preset posture angle threshold and comparing the collected current user's posture deviation duration with a preset duration; S183, if the current user's posture deviation data is greater than the preset posture angle threshold and the posture deviation duration is greater than or equal to the preset duration, then the status level of the current user's posture deviation data is an abnormal state, and the corresponding control step is executed. This setting ensures that the current user's posture deviation data is judged to be an abnormal state only when the posture deviation data is greater than the preset angle threshold and the posture deviation duration is greater than or equal to the preset duration. This dual judgment avoids misjudgment due to brief changes in posture, ensuring the accuracy and stability of the abnormal posture status judgment.

[0031] In this embodiment of the invention, the types of sitting posture deviations are prioritized according to their risk. The risk priority refers to ranking different types of sitting posture deviations (e.g., hunchback, forward head posture, spinal tilt, and head tilt) according to the severity of their impact on the user's health. For example, long-term forward head posture may put greater pressure on the cervical spine, and its priority may be higher than that of slight head tilt. See appendix Figure 5 S183, after the step of determining that the current user's posture deviation data is in an abnormal state, if the current user's posture deviation data is greater than the preset posture angle threshold and the posture deviation duration is greater than or equal to the preset duration, the health judgment step further includes: S184, Based on the abnormal sitting posture deviation data, determine the type of abnormal sitting posture deviation. S185, Based on the type of posture deviation in an abnormal state, execute the corresponding control step, which includes: S186, if only the sagittal plane cervical anteversion angle is greater than the corresponding preset sitting posture angle threshold, then the head is determined to be tilted forward, and the fourth control step is executed. The fourth control step includes the fourth screen movement step and the prompting step. The fourth screen movement step is to drive the screen terminal to move backward relative to the current user in space; the prompting step is to prompt the sitting posture adjustment through at least one of the following methods: voice prompt, screen image prompt and indicator light prompt. S187, if only the coronal plane lateral deviation angle is greater than the corresponding preset sitting posture angle threshold, then spinal tilt is determined and the fifth control step is executed. The fifth control step includes the fifth screen motion step, which is to drive the screen terminal to rotate relative to the current user in space to match the viewing angle. S188, if only the coronal plane lateral flexion angle and the horizontal torsion angle are greater than the corresponding preset sitting posture angle threshold, then it is determined that the head is tilted and the sixth control step is executed. The sixth control step includes the sixth screen motion step, which is to drive the screen terminal to rotate relative to the current user in space to match the viewing angle. S189: If only the sagittal anterior tilt angle is greater than the corresponding preset sitting posture angle threshold, then it is determined to be hunchback, and the seventh control step is executed. The seventh control step includes a seventh screen movement step and a prompting step. The seventh screen movement step drives the screen terminal to move upward relative to the current user in space. The prompting step provides posture adjustment prompts through at least one of the following methods: voice prompts, screen image prompts, and indicator light prompts.
