Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment brackets, and in particular to an intelligent adjustment bracket based on multi-parameter fusion. Background Art

[0002] In modern smart devices and automated systems, the ambient lighting conditions of the user have a significant impact on the accuracy and reliability of the system. Especially in scenarios involving behavioral monitoring, such as eye tracking and head posture detection, light fluctuations interact with user parameters (such as line of sight angle, blink frequency, head position, etc.), complicating the data analysis process. Changes in artificial light sources, fluctuations in natural light, and individual differences in users (such as eye sensitivity to light, range of head movement, etc.) will interfere with the sensor's accurate perception of the actual environment. In this case, relying solely on fixed lighting standards or behavioral parameters for judgment is prone to errors due to the complex interaction between ambient light and user behavior.

[0004] It can be seen that the mobile smartphone holder has the following problems: the coordination of various mechanisms makes the operation of the entire holder more dependent on multiple moving parts, increasing the probability of failure; due to the integration of multiple mechanical components and control systems, the overall weight is relatively large, affecting the convenience and mobility of the holder, and multiple movable parts may affect the overall stability of the holder, especially when used on an unstable ground; the mutual adjustment of multiple mechanisms leads to a long system response time, especially when frequent adjustments are required during use, the operating efficiency is low, and it is difficult to achieve fast and accurate angle and height adjustment.

[0055] Furthermore, the control module is further configured to activate the eye training mode when the viewing time of the target reaches a preset viewing time threshold;

[0056] The eye training mode is to control the folding bracket to move back and forth a preset number of times based on the slide rail at the preset adjustment speed.

[0057] Compared with the prior art, the beneficial effect of the present invention lies in that, based on the fusion analysis of multiple parameters such as sight angle, number of blinks, relative distance of the head, ambient light intensity and number of light sources, the abnormal lighting situation is identified through the abnormal judgment module, and the severity level is determined in combination with the sight angle and relative distance, so as to achieve precise graded adjustment. The adjustment module adjusts the position of the bracket according to the judgment result and the blinking frequency, and the correction module further optimizes the adjustment process to make the bracket more adaptable. The update module dynamically optimizes the light impact threshold and adjustment speed in combination with the parameter changes in the adjustment process, and has self-learning capabilities to ensure stability and comfort under long-term use. Through real-time interaction and feedback optimization of multiple parameters, it can adapt to different environments and user states, realize personalized adjustment, improve use comfort, reduce visual fatigue, and enhance the experience of long-term use, effectively solving the problems of low adjustment accuracy and poor adaptability caused by over-reliance on single parameter judgment.

[0058] Furthermore, through real-time statistical analysis of fluctuations in ambient light intensity, it is possible to accurately identify lighting anomalies, effectively avoid misjudgments caused by unstable lighting in a multi-light source environment, and ensure timely response to environmental changes, thereby improving the accuracy of the bracket's dynamic adjustment and the stability of the user's viewing experience.

[0059] Furthermore, by performing differential and standard deviation statistics on the continuously collected gaze angle and head distance data, the aim is to quantify the user's subtle movements during viewing, thereby accurately reflecting posture fluctuations caused by abnormal ambient lighting. This can avoid misjudgments due to occasional noise or instantaneous fluctuations, while ensuring that the bracket position can be adjusted promptly and smoothly under actual abnormal conditions, meeting the needs of rapid response while ensuring the stability of the adjustment process, thereby significantly improving the user's visual comfort and overall adjustment performance. By visualizing the fluctuations in angle changes and distance changes and calculating their synchronization, it is possible to accurately determine whether the user's posture and lighting changes are consistent, thereby effectively identifying the severity of lighting anomalies. This method, based on curve and similarity analysis, can more accurately assess the impact of lighting fluctuations on users, achieve more intelligent and reliable adjustments, and enhance user experience and comfort.

[0060] Furthermore, by combining blink count with light impact levels, the adjustment module accurately determines the user's discomfort level and optimizes the viewing experience by adjusting the folding stand's position. Changes in blink count directly reflect eye fatigue, and the introduction of preset adjustment speeds ensures a smooth adjustment process, avoiding the additional interference caused by drastic changes. It can adapt to different individual eye conditions, providing a more comfortable viewing experience in dynamic environments while also improving sensitivity and response efficiency to light interference.

[0061] Furthermore, by analyzing the fluctuations in the number of blinks, it is possible to effectively detect the onset of visual fatigue, and by calculating the adjustment amount, the position of the folding bracket can be adjusted in real time to optimize the user's line of sight and viewing distance, thereby achieving dynamic visual comfort adjustment. By calculating the standard deviation and relative deviation, the degree of fatigue can be accurately judged, avoiding misjudgments caused by fluctuations in a single parameter (such as the number of blinks), making the adjustment process more scientific and effective. In addition, the combination of preset adjustment coefficients and adjustment speeds further enhances adaptability to different environments and personalized responses to user needs.

[0062] Furthermore, during the adjustment process, fluctuations in sight angle and relative distance are monitored in real time, and intelligent corrections are made by calculating the standard deviation of these fluctuations, thus avoiding the discomfort caused by overly rapid or inappropriate adjustments. This correction method based on actual fluctuation data can accurately reflect user needs.

[0063] Furthermore, through normalization and consistency calculation, the correction unit accurately measures the consistency of changes between line of sight angle and relative distance, ensuring a more precise adjustment process. When fluctuations are inconsistent, the adjustment amount is increased to compensate for the instability, resulting in smoother bracket position adjustment and effectively reducing errors caused by inconsistent fluctuations.

[0064] Furthermore, by calculating fluctuations in the correction amount and the number of light sources, the update module accurately captures uncertainties in the lighting environment and the adjustment process. When these fluctuations exceed preset standards, the light impact threshold and adjustment speed are adjusted accordingly, enabling smarter and more flexible adjustments, effectively reducing misjudgments caused by environmental changes or fluctuations in device status.

[0065] Furthermore, by calculating and comparing fluctuations in the correction amount and the number of light sources in real time, the update unit can dynamically adjust response parameters, such as adjustment speed and light impact threshold, to quickly respond to actual environmental fluctuations and improve adaptability to changes. When light and position fluctuations are large, the adjustment speed is automatically accelerated to ensure the target remains in the optimal viewing state. When environmental fluctuations are small, the adjustment is automatically slowed down, saving energy and improving comfort. This improves stability and accuracy, and avoids over-adjustments and overly sensitive responses.

[0066] Furthermore, by starting the eye training mode within a specific time, it can effectively relieve eye fatigue caused by long-term viewing, promote eye health, and help the target to exercise the eyes unconsciously, avoiding vision loss caused by too long of static viewing, thereby improving the target's user experience and health level.

[0073] See also Figure 1As shown, it is a structural diagram of the intelligent adjustment bracket based on multi-parameter fusion in this embodiment;

[0074] This embodiment provides an intelligent adjustable bracket based on multi-parameter fusion, including:

[0075] An information collector 1 is used to collect in real time the target's eye sight angle, blink frequency, head relative distance, ambient light intensity, and number of light sources during viewing of the target through a foldable stand 2 positioned at a preset distance;

[0076] A processor 3 connected to the information collector 1, comprising an abnormality determination module and a level determination module;

[0077] The abnormality determination module is used to determine whether there is a light impact abnormality according to the light intensity and a preset light impact threshold, and form an abnormality determination result;

[0078] The level determination module is configured to determine the severity level of the abnormal light impact situation according to the abnormality determination result, the sight angle, and the relative distance, and form a level determination result;

[0079] a motor controller 4 connected to the processor, comprising an adjustment module, a correction module, an update module and a control module;

[0080] The adjustment module is used to adjust the position of the folding bracket 2 according to the level determination result, the number of blinks and a preset adjustment speed to form an adjusted position;

[0081] The correction module is used to correct the adjusted position according to the sight angle and the relative distance in the process of forming the adjusted position to form a corrected position;

[0082] The updating module is configured to update the preset light impact threshold according to the number of the correction positions formed within the preset threshold adjustment time and the number of light sources to form an updated light impact threshold, or update the preset adjustment speed to form an updated adjustment speed;

[0083] The control module is used to control the folding bracket to move to the adjustment position or the correction position formed based on the updated light impact threshold or the updated adjustment speed.

[0084] The folding bracket 2 is set based on a preset placement distance, that is, in the direction facing the target, the starting point of the slide rail 5 close to the target is used as a reference point, and the bracket is positioned according to the preset placement distance.

[0085] The information collector integrates multiple sensors to acquire key parameters of the target in real time while viewing the folded stand. The gaze angle is captured by an eye-tracking sensor, which determines gaze direction by analyzing eye movement trajectories. Blinks are recorded by an infrared camera or high-speed image sensor, which records eyelid opening and closing, and is filtered by a threshold for high-frequency blinks per unit time. The relative head distance is calculated by a binocular depth camera, which continuously measures the depth of the target's facial features to obtain precise distance. Ambient light intensity is collected by a light sensor, which combines multi-point measurement data to calculate the overall light level. The number of light sources is detected by an image sensor combined with brightness distribution analysis. All data is collected in real time by the information collector and transmitted to the processor for intelligent analysis to support dynamic adjustment of the stand.

[0086] The preset placement distance refers to the initial placement position of the folding bracket pre-set in the direction facing the target with reference to the starting point of the slide rail. It depends on ergonomics, optimal viewing distance and the requirements of the target application scenario. It is usually set between 50 cm and 80 cm. In this embodiment, it is set to 65 cm, which can provide an ergonomic optimal viewing distance, reduce visual fatigue and improve usage comfort.

[0087] The preset light impact threshold refers to the threshold used to determine whether the ambient light intensity has an abnormal impact on viewing. It depends on the ambient light level, sensor sensitivity, and user visual comfort requirements. It is usually set between 300 lux and 700 lux. In this embodiment, it is set to 500 lux. It can balance sensitivity and stability to ensure reliable detection of lighting anomalies in different environments and avoid misjudgment.

[0088] The preset adjustment speed refers to the preset rate at which the folding bracket moves during the adjustment process, which depends on the mechanical structure performance, response time requirements and user comfort experience. It is usually set between 0.5 cm / s and 2.0 cm / s. In this embodiment, it is set to 1.0 cm / s, which can ensure that the bracket moves smoothly and responds promptly, while avoiding sudden speed changes that may cause user discomfort.

[0089] The preset threshold adjustment time refers to the time period for updating the preset light impact threshold or adjustment speed based on the collected data within a certain period of time. It depends on the response speed, the frequency of environmental changes and the data stability requirements. It is usually set between 30 seconds and 5 minutes. In this embodiment, it is set to 2 minutes, which balances the timely response to environmental changes and stability, avoids too frequent parameter fluctuations, and improves the robustness of the overall adjustment.

[0090] This intelligently adjustable bracket uses an information collector to collect real-time data on the user's gaze angle, blink frequency, head distance, ambient light intensity, and number of light sources. The abnormality determination module then detects abnormal light effects. The level determination module classifies the abnormality based on its severity, and the adjustment module adjusts the bracket's position based on the number of blinks and a preset adjustment speed. The correction module further optimizes the adjustment position to ensure the stability of the user's line of sight. Subsequently, the update module updates the light impact threshold or adjustment speed based on the correction data and changes in the light source to improve adaptability. Finally, the control module drives the folding bracket to the optimal position based on the optimized parameters, achieving intelligent adaptive adjustment.

[0091] Based on a fusion analysis of multiple parameters such as line of sight angle, number of blinks, relative head distance, ambient light intensity, and number of light sources, the abnormal lighting conditions are identified through the abnormality judgment module, and the severity level is determined in combination with the line of sight angle and relative distance, thus achieving precise graded adjustment. The adjustment module adjusts the position of the bracket based on the judgment results and blinking frequency, and the correction module further optimizes the adjustment process to make the bracket more adaptable. The update module dynamically optimizes the light impact threshold and adjustment speed based on parameter changes during the adjustment process, and has self-learning capabilities to ensure stability and comfort under long-term use. Through real-time interaction and feedback optimization of multiple parameters, it can adapt to different environments and user states, achieve personalized adjustment, improve user comfort, reduce visual fatigue, and enhance the long-term use experience, effectively solving the problems of low adjustment accuracy and poor adaptability caused by over-reliance on a single parameter judgment.

[0092] Please continue reading Figure 2 As shown, it is a determination logic diagram of the abnormality determination result formed by the abnormality determination unit of this embodiment;

[0093] The abnormality determination module includes:

[0094] a light intensity fluctuation calculation unit, configured to calculate the standard deviation of all the light intensities within a preset abnormality determination time period when the light intensity is within a preset standard light intensity range, to form a light intensity fluctuation value;

[0095] The abnormality determination unit is connected to the light intensity fluctuation calculation unit and is used to determine that the light influence abnormality exists when the light intensity fluctuation value is greater than the preset light influence threshold value, and form the abnormality determination result.

[0096] First, the light intensity fluctuation calculation unit performs statistical processing on the collected ambient light intensity data within the preset abnormality judgment time, and calculates its standard deviation to form a light intensity fluctuation value; then, the abnormality judgment unit compares the light intensity fluctuation value with the preset light impact threshold. When the fluctuation value exceeds the preset threshold, it is determined that there is a light impact abnormality, and a corresponding abnormality judgment result is generated for subsequent adjustment.

[0097] Through real-time statistical analysis of fluctuations in ambient light intensity, it is possible to accurately identify lighting anomalies, effectively avoid misjudgments caused by unstable lighting in multi-light source environments, and ensure timely response to environmental changes, thereby improving the accuracy of the bracket's dynamic adjustment and the stability of the user's viewing experience.

[0098] Please continue reading Figure 3 As shown, it is a decision logic diagram of the level determination result formed by the level determination unit of this embodiment;

[0099] The level determination module includes:

[0100] An angle change calculation unit, used to calculate the difference of the sight angle at adjacent moments within a preset level determination time when forming the abnormality determination result, to form a plurality of angle change speeds;

[0101] an angle change fluctuation calculation unit, connected to the angle change calculation unit, for calculating the standard deviation of all the angle change speeds to form an angle change fluctuation value;

[0102] a distance change calculation unit, configured to calculate the difference in the relative distances at adjacent moments within a preset level determination time period when forming the abnormality determination result, to form a distance change speed;

[0103] a distance change fluctuation calculation unit, connected to the distance change calculation unit, for calculating all the distance change speed standard deviations to form a distance change fluctuation value;

[0104] an angle curve drawing unit connected to the angle change fluctuation calculation unit, for drawing a change curve of the angle change fluctuation value within the preset level determination time to form an angle curve;

[0105] a distance curve drawing unit connected to the distance change fluctuation calculation unit, for drawing a change curve of the distance change fluctuation value within the preset level determination time to form a distance curve;

[0106] a synchronization calculation unit, connected to the angle curve drawing unit and the distance curve drawing unit, respectively, for calculating the cosine similarity between the angle curve and the distance curve to form a change synchronization degree;

[0107] The level determination unit is connected to the synchronization calculation subunit and is used to determine that the degree of the abnormal light influence is a serious level when the change synchronization is less than a preset standard synchronization, and form the level determination result.

[0108] The preset level determination time refers to the time period used to collect and analyze the user's line of sight and head distance data to assess the severity of the lighting anomaly. It depends on the frequency of the user's posture changes and the characteristics of the ambient light fluctuations. It is usually set between 10 seconds and 1 minute. In this embodiment, it is set to 30 seconds. This setting can strike a balance between quickly responding to changes in user status and ensuring data stability, thereby achieving accurate grading and timely adjustment.

[0109] The preset standard synchronization is a threshold used to measure the consistency of changes in the angle curve and distance curve. It is determined by the user's tolerance for abnormal light effects and the accuracy requirements in actual applications, and is typically set between 0.8 and 1.0. In this embodiment, the preset standard synchronization is set to 0.9, which balances calculation accuracy and response speed, ensuring accuracy while reducing the probability of misjudgment, thereby better adapting to different usage environments and lighting conditions.

[0110] After forming an abnormality determination result, the angle change calculation unit performs differential calculations on the continuously collected sight angle data within a preset level determination duration to obtain a number of angle change speeds. Subsequently, the angle change fluctuation calculation unit calculates the standard deviation of these speeds to generate an angle change fluctuation value. Simultaneously, the distance change calculation unit compares the relative distances between the user and the bracket at adjacent moments to obtain the distance change speed, and the distance change fluctuation calculation unit calculates the standard deviation to generate the distance change fluctuation value. Finally, within the preset level determination duration, the angle curve drawing unit and the distance curve drawing unit respectively draw curves for the sight angle change fluctuation value and the relative distance change fluctuation value, forming an angle curve and a distance curve. The synchronization calculation unit calculates the cosine similarity of these two curves to generate a change synchronization degree. If the change synchronization degree is less than the preset standard synchronization degree, the level determination subunit determines the degree of the light impact abnormality as severe and outputs the level determination result.

[0111] By performing differential and standard deviation analysis on continuously collected gaze angle and head distance data, the system aims to quantify subtle user movements during viewing, accurately reflecting posture fluctuations caused by abnormal ambient lighting. This avoids misjudgments due to occasional noise or transient fluctuations, while ensuring timely and smooth adjustment of the bracket position under actual abnormal conditions. This not only meets the need for rapid response but also ensures the stability of the adjustment process, significantly improving the user's visual comfort and overall adjustment performance. By visualizing the fluctuations in angle and distance changes and calculating their synchronization, it is possible to accurately determine whether the user's posture and lighting changes are consistent, effectively identifying the severity of lighting anomalies. This method, based on curve and similarity analysis, can more accurately assess the impact of lighting fluctuations on users, enabling more intelligent and reliable adjustments and improving user experience and comfort.

[0112] Specifically, the adjustment module includes:

[0113] a number comparison unit, for comparing the number of blinks with a preset number threshold when forming the level determination result, to form a number comparison result;

[0114] An adjustment unit is connected to the number comparison unit and is used to adjust the position of the folding bracket according to the number comparison result, the number of blinks and the preset adjustment speed to form the adjusted position.

[0115] The preset number threshold refers to the critical value of the number of high-frequency blinks set in advance per unit time, which is used to determine whether the user has abnormal eye use due to the influence of the light environment. It depends on the normal physiological blinking frequency and the user's tolerance for visual fatigue, and is usually set between 15 and 25 times per minute; in this embodiment, it is set to 20 times so that the adjustment mechanism can be triggered in time when the user's blinking frequency exceeds this range, thereby improving viewing comfort and reducing eye fatigue.

[0116] After the adjustment module determines the level, the frequency comparison unit first compares the user's high-frequency blink count per unit time with a preset threshold to determine whether light-induced eye discomfort is occurring. If the blink count is abnormally high, the adjustment unit adjusts the folding bracket to a new position based on the comparison result, the current blink count, and the preset adjustment speed, thereby optimizing the viewing environment.

[0117] By combining blink count with light exposure levels, the adjustment module accurately determines the user's discomfort level and adjusts the folding stand position to optimize the viewing experience. Changes in blink count directly reflect eye fatigue, and the introduction of preset adjustment speeds ensures a smooth adjustment process, avoiding the additional interference caused by drastic changes. It can adapt to different individual eye conditions, providing a more comfortable viewing experience in dynamic environments while also improving sensitivity and response efficiency to light interference.

[0118] Please continue reading Figure 4 As shown, it is a determination logic diagram of the fatigue determination result formed by the fatigue determination subunit of this embodiment;

[0119] The adjustment unit includes:

[0120] a frequency fluctuation calculation subunit, configured to calculate a standard deviation of the number of blinks within a preset position adjustment time period to form a frequency fluctuation value when the number comparison result shows that the number of blinks is greater than a preset number threshold;

[0121] a fatigue determination subunit, connected to the number fluctuation calculation subunit, for determining the presence of fatigue when the number fluctuation value is greater than a preset number fluctuation threshold, and forming a fatigue determination result;

[0122] an adjustment amount calculation subunit, connected to the fatigue determination subunit, for increasing the preset placement distance according to a relative deviation between the number fluctuation value and the preset number fluctuation threshold and a preset adjustment coefficient to form an adjustment amount when forming the fatigue determination result;

[0123] The adjusting subunit is connected to the adjustment amount calculating subunit and is used to adjust the position of the folding bracket based on a preset adjustment speed and the adjustment amount to form the adjusted position.

[0124] The preset position adjustment time is the maximum time allowed when adjusting the folding stand. It is determined by user comfort and the smoothness of the adjustment process to avoid overly fast or slow adjustments that affect the user experience. It is typically set between 2 and 5 seconds. In this embodiment, it is set to 3 seconds to ensure a smooth adjustment process that does not interfere with the user's vision and avoid unnecessary waiting due to excessive adjustment time.

[0125] The preset blink frequency fluctuation threshold refers to the standard value used to determine fatigue when calculating the blink frequency fluctuation. It depends on the blink frequency fluctuation characteristics of the user under normal use conditions and is usually set between 5 times / second and 10 times / second. In this embodiment, it is set to 7 times / second to better match the user's normal visual activity range and to be able to detect potential fatigue problems at an early stage.

[0126] The preset adjustment coefficient is a proportional coefficient used to adjust the change in placement distance, which depends on the impact of the change in viewing distance on user comfort. It is usually set between 0.2 and 0.5. In this embodiment, it is set to 0.3 so that the placement distance can be changed more accurately during adjustment, thereby effectively alleviating fatigue and optimizing the user's viewing angle.

[0127] First, based on the comparison of the number of blinks with a preset threshold, the standard deviation of the number of blinks is calculated to obtain a blink fluctuation value. When the blink fluctuation value exceeds the preset threshold, visual fatigue is determined, and an adjustment amount is further calculated based on this fatigue determination. The adjustment amount is calculated based on the relative deviation between the blink fluctuation value and the preset threshold and a preset adjustment coefficient. Ultimately, the preset placement distance is increased and the position of the folding stand is adjusted, thereby improving the viewing environment and alleviating the user's visual fatigue.

[0128] By analyzing fluctuations in the number of blinks, it is possible to effectively detect the onset of visual fatigue and, by calculating the adjustment amount, adjust the position of the folding bracket in real time to optimize the user's line of sight and viewing distance, thereby achieving dynamic visual comfort adjustment. By calculating the standard deviation and relative deviation, the degree of fatigue can be accurately judged, avoiding misjudgments caused by fluctuations in a single parameter (such as the number of blinks), making the adjustment process more scientific and effective. In addition, the combination of preset adjustment coefficients and adjustment speeds further enhances adaptability to different environments and personalized responses to user needs.

[0129] Specifically, the correction module includes:

[0130] a duration calculation unit, configured to calculate a ratio of the adjustment amount to the preset adjustment speed to form a correction duration;

[0131] an angle fluctuation calculation unit connected to the duration calculation unit, for calculating the standard deviation of all the sight angles within the correction duration to form an angle fluctuation value;

[0132] a distance fluctuation calculation unit connected to the duration calculation unit, for calculating the standard deviation of all the relative distances within the corrected duration to form a distance fluctuation value;

[0133] A correction unit is connected to the duration calculation unit and the time length calculation unit respectively, and is used to correct the adjustment position according to the angle fluctuation value and the distance fluctuation value to form a correction position.

[0134] The duration calculation unit first calculates the ratio of the adjustment amount to the preset adjustment speed to determine the correction duration. Next, the angle fluctuation calculation unit and the distance fluctuation calculation unit calculate the standard deviation of the line of sight angle and relative distance, respectively, within the correction duration to obtain the angle fluctuation value and distance fluctuation value. Finally, the correction unit adjusts the position of the folding bracket based on these two fluctuation values to form the final corrected position. This process dynamically adjusts the bracket position to optimize the user's viewing angle and comfort.

[0135] During the adjustment process, the system monitors fluctuations in sight angle and relative distance in real time and makes intelligent corrections by calculating the standard deviation of these fluctuations, thus avoiding discomfort caused by overly rapid or inappropriate adjustments. This correction method, based on actual fluctuation data, accurately reflects user needs.

[0136] Specifically, the correction unit includes:

[0137] a normalization subunit, configured to perform normalization processing on the angle fluctuation value to form an angle standard fluctuation value, and to perform normalization processing on the distance fluctuation value to form a distance standard fluctuation value;

[0138] a consistency calculation subunit, connected to the standardization subunit, for calculating a correlation coefficient between the angle standard fluctuation value and the distance standard fluctuation value to form a fluctuation consistency;

[0139] a correction amount calculation subunit, connected to the consistency calculation subunit, for increasing the adjustment amount according to a relative deviation between the fluctuation consistency and the preset standard consistency and a preset correction coefficient to form a correction amount when the fluctuation consistency is less than a preset standard consistency;

[0140] The correction subunit is connected to the correction amount calculation subunit and is used to correct the position of the folding bracket based on the preset adjustment speed and the correction amount to form the corrected position.

[0141] The preset standard consistency is a threshold used to measure the correlation between angle fluctuations and distance fluctuations. It depends on the requirements for fluctuation synchronization and the changing characteristics of the lighting environment. It is usually set between 0.8 and 1.0. In this embodiment, it is set to 0.9, which can ensure that in most cases, the angle change and the distance change are sufficiently synchronized to avoid misjudgment, accurately judge the user status, and ensure the accuracy of adjustment.

[0142] The preset correction coefficient is a proportional coefficient used to adjust the amplitude of the change in the position of the folding bracket. It depends on the adjustment accuracy requirements, user comfort and the response speed of the bracket. It is usually set between 0.2 and 0.5. In this embodiment, it is set to: In this embodiment, it is set to 0.3, which can balance the adjustment fineness and response speed, ensure that the bracket moves smoothly and ergonomically, and improve the comfort of use.

[0143] The correction unit first normalizes the angle and distance fluctuation values through the normalization subunit, generating standard angle and distance fluctuation values. Next, the consistency calculation subunit calculates the correlation coefficient between these two standard fluctuation values to form a fluctuation consistency. If the fluctuation consistency is less than the preset standard consistency, the correction calculation subunit increases the adjustment amount based on the relative deviation between the fluctuation consistency and the preset standard consistency. Finally, the correction subunit, combined with the preset adjustment speed, adjusts the position of the folding bracket to a corrected position, optimizing the user's viewing angle and comfort.

[0144] Through normalization and consistency calculation, the correction unit accurately measures the consistency of changes in line of sight angle and relative distance, ensuring more precise adjustments. When fluctuations are inconsistent, the adjustment amount is increased to compensate for the instability, resulting in smoother bracket position adjustment and effectively reducing errors caused by inconsistent fluctuations.

[0145] Specifically, the update module includes:

[0146] a correction quantity fluctuation calculation unit, configured to calculate a standard deviation of the number of correction positions formed within the preset threshold adjustment time period to form a correction quantity fluctuation value;

[0147] a light source quantity fluctuation calculation unit, configured to calculate a standard deviation of the light source quantity within the preset threshold adjustment time period to form a light source quantity fluctuation value;

[0148] An updating unit is connected to the correction quantity fluctuation calculation unit and the light source quantity fluctuation calculation unit respectively, and is used to update the preset light impact threshold according to the correction quantity fluctuation value and the light source quantity fluctuation value to form the updated light impact threshold, or to update the preset adjustment speed to form the updated adjustment speed.

[0149] The update module evaluates fluctuations within the preset threshold adjustment period by calculating the standard deviation of the number of corrected positions (corrected number fluctuation value) and the standard deviation of the number of light sources (light source number fluctuation value). The corrected number fluctuation value reflects the frequency of position adjustments, while the light source number fluctuation value describes the volatility of the ambient light source. This fluctuation data is processed by the update unit, and the preset light impact threshold and adjustment speed are updated based on the fluctuations, thereby optimizing responsiveness and adapting to dynamic environments with changing lighting and adjustment needs.

[0150] By calculating fluctuations in the correction amount and the number of light sources, the updated module accurately captures uncertainties in the lighting environment and the adjustment process. When these fluctuations exceed preset standards, the light impact threshold and adjustment speed are adjusted accordingly, enabling smarter and more flexible adjustments, effectively reducing misjudgments caused by environmental changes or fluctuations in device status.

[0151] Specifically, the updating unit includes:

[0152] a correction deviation calculation subunit, configured to calculate a relative deviation between the correction quantity fluctuation value and the preset correction fluctuation value threshold value when the correction quantity fluctuation value is greater than a preset correction fluctuation threshold value, to form a correction deviation;

[0153] a light source deviation calculation subunit, configured to calculate a relative deviation between the light source quantity fluctuation value and the preset light source fluctuation threshold value when the light source quantity fluctuation value is greater than a preset light source fluctuation threshold value, to form a light source deviation;

[0154] an update deviation calculation subunit, connected to the correction deviation calculation subunit and the light source deviation calculation subunit respectively, for calculating a relative deviation between the correction deviation and the light source deviation to form an update deviation;

[0155] An updating subunit, which is connected to the update deviation calculation subunit, is used to increase the preset adjustment speed according to the relative deviation between the absolute value of the update deviation and the preset update deviation threshold and the preset update coefficient when the update deviation is a positive number and the absolute value of the update deviation is greater than the preset update deviation threshold, so as to form the update adjustment speed; and, when the update deviation is a negative number and the absolute value of the update deviation is greater than the preset update deviation threshold, reduce the preset light impact threshold according to the relative deviation between the absolute value of the update deviation and the preset update deviation threshold and the preset update coefficient, so as to form the updated light impact threshold.

[0156] The preset correction fluctuation threshold is the maximum fluctuation range allowed during the adjustment process, which is generally determined by the tolerance and stability requirements of the target position in the actual application. It is generally set between 5% and 15%, and in this embodiment is set to 10% to ensure that a certain amount of fluctuation can be tolerated and necessary adjustments can be made, while avoiding excessive adjustments that may cause unnecessary reactions, thereby ensuring stability and efficiency.

[0157] The preset light source fluctuation threshold is the permissible range of ambient light intensity fluctuations, typically determined by the magnitude of ambient lighting variations and the need for lighting stability. It's typically set between 3% and 10%, but in this example, it's set to 5%. This ensures adaptability to lighting changes while avoiding over-adjustment due to minor changes, ensuring a comfortable visual environment.

[0158] The preset update deviation threshold is an important value used to determine the significance of update deviation, which is generally determined by the required adjustment accuracy and the magnitude of environmental changes. It is generally set between 1% and 5%, and in this embodiment is set to 3%, which can balance the need for adjustment sensitivity and avoid over-responsiveness, ensuring a balance between response accuracy and user experience.

[0159] The preset update coefficient is a coefficient used to control the response speed. It is usually determined based on the adjustment capability, environmental conditions, and the desired adjustment speed. It is generally set between 1 and 3. In this embodiment, it is set to 2. It can provide an appropriate adjustment speed when responding to update deviations, ensuring that the adjustment process is neither too intense nor too slow, and can quickly adapt to environmental changes.

[0160] The update unit calculates the correction deviation and light source deviation, respectively, based on the relative deviations between the correction quantity fluctuation value and the light source quantity fluctuation value and their respective preset fluctuation thresholds. If the correction quantity fluctuation value or the light source quantity fluctuation value exceeds its preset fluctuation threshold, the current state is evaluated by calculating its relative deviation. Next, the update deviation calculation subunit combines the relative deviations of the correction deviation and light source deviation to form an update deviation. If the update deviation is positive and its absolute value is greater than the preset threshold, the position of the folding bracket is adjusted by increasing the preset adjustment speed. If the update deviation is negative and its absolute value is greater than the threshold, the preset light impact threshold is reduced to optimize the lighting conditions, thereby adjusting the range of the light source impact.

[0161] By calculating and comparing fluctuations in the correction amount and the number of light sources in real time, the update unit dynamically adjusts response parameters, such as adjustment speed and light impact threshold, to quickly respond to actual environmental fluctuations and improve adaptability to changes. When light and position fluctuations are large, the adjustment speed is automatically accelerated to ensure the target remains in the optimal viewing state. When environmental fluctuations are small, the adjustment is automatically slowed down, saving energy and improving comfort. This improves stability and accuracy, and avoids over-adjustments and overly sensitive responses.

[0162] Specifically, the control module is further configured to activate the eye training mode when the target's viewing time reaches a preset viewing time threshold;

[0163] The eye training mode is to control the folding bracket to move back and forth a preset number of times based on the slide rail 5 at the preset adjustment speed.

[0164] The preset viewing time threshold is the target viewing time limit before eye training mode is activated. It is based on research and health guidelines and is typically set between 30 minutes and 2 hours. In this embodiment, it is set to 1 hour to help ensure that eye training is initiated promptly after long periods of continuous viewing, reducing eye fatigue and protecting vision health.

[0165] The preset number of movements refers to the number of back-and-forth movements the folding stand performs after eye training mode is activated. This number typically depends on comfort and training effectiveness, and is set between 5 and 15 times. In this embodiment, it is set to 10 times, which effectively trains the eyes and avoids excessive fatigue, while ensuring a moderate amount of exercise, enhancing comfort, and promoting relaxation of the eye muscles.

[0166] When the control module detects that the subject's viewing time has reached a preset viewing time threshold, it triggers eye training mode. At this point, the folding stand moves back and forth on the rails at a preset adjustment speed, performing the preset number of movements to ensure the subject's eyes receive adequate rest and exercise.

[0167] By starting the eye training mode within a specific time, it can effectively relieve eye fatigue caused by long-term viewing, promote eye health, and help the target exercise the eyes unconsciously, avoiding vision loss caused by long-term static viewing, thereby improving the target's user experience and health level.
