Abstract
Description
Technical Field
[0001] This invention relates to the field of display screen adjustment technology, and in particular to a method, medium, and device for intelligent adjustment of display screen height and angle. Background Technology
[0002] Office spaces typically provide employees with desktop computers, and employees manually adjust the screen height and angle according to their individual needs, rarely needing to adjust them again during work. However, in reality, employees frequently change their sitting postures. These changes alter their eye level and the angle between their line of sight and the screen, making it difficult to ensure a proper alignment between their eyes and the screen. Furthermore, while some methods exist for adjusting screens based on eye position, these methods prioritize eye comfort while neglecting neck comfort and health.
[0003] Therefore, developing a display adjustment solution that takes into account the comfort and health of users' eyes and neck is one of the urgent problems to be solved. Summary of the Invention
[0004] In order to solve at least one of the technical problems mentioned in the background art, the present invention aims to provide a method, medium and device for intelligent adjustment of display screen height and angle, which can take into account the comfort and health of the user's eyes and neck.
[0005] In a first aspect, the present invention provides a method for intelligent adjustment of display screen height and angle, comprising the following steps: S1, detects the human posture of the person at the workstation, including the first angle between the neck and torso; S2, calculate whether the first included angle is within the set first threshold range. If so, adjust the display screen to be at the height and angle of the human eye below the current first included angle between the neck and torso; otherwise, adjust the display screen to be at the height and angle of the human eye when the first included angle between the neck and torso is at the set first angle.
[0006] In some embodiments of the first aspect of the invention, the method further includes the following step before step S1: S0: Identify whether the personnel at the workstation are using the display screen for work. If so, proceed to step S1; otherwise, maintain the current height and angle of the display screen.
[0007] In some embodiments of the first aspect of the present invention, the method for identifying whether a display screen is used for office work is as follows: The system collects an overhead view of the workstation and uses a trained model to detect the hands, keyboard, and mouse. If the hands and keyboard overlap, and the hands and mouse also overlap, it is considered that the user is using the monitor for work.
[0008] In some embodiments of the first aspect of the invention, the method for adjusting the display screen to a height and angle directly facing the human eye below the current first angle between the neck and torso is as follows: Given the first angle between the neck and torso, determine whether the second angle between the person's line of sight and the horizontal direction is within the second threshold range. If the second included angle is within the second threshold range, then the current height of the display screen remains unchanged, and the third included angle formed by the line of sight and the screen is calculated to see if it is within the third threshold range. If the third included angle is within the third threshold range, the current angle of the display screen remains unchanged; otherwise, the angle of the display screen is rotated so that the display screen and the line of sight form a third angle. If the second included angle is not within the second threshold range, adjust the height of the display screen until the center point of the display screen is at the same height as the eyes, and rotate the angle of the display screen so that the display screen and the line of sight form a third angle.
[0009] In some embodiments of the first aspect of the present invention, the method for adjusting the display screen to the height and angle at which it is directly facing the human eye when the first angle between the neck and the torso is at a set first angle is as follows: Calculate the height of the human eye and the line of sight when the first angle between the neck and torso is adjusted to a set first angle; Adjust the height of the display screen until the center point of the screen is at the same height as your eyes, and rotate the screen so that the screen and your line of sight form a third angle.
[0010] In some embodiments of the first aspect of the present invention, the line of sight is the line connecting the human eye and the center point of the display screen.
[0011] In some embodiments of the first aspect of the invention, the first angle is 0° or the center value of a first threshold range.
[0012] In some embodiments of the first aspect of the present invention, the method for detecting the first included angle between the neck and the torso is as follows: The side view image of the person being collected is used to identify the head, shoulders, and hips in the side view image using key points of the human skeleton. The head and shoulders are connected by a first line, and the shoulders and hips are connected by a second line. The angle between the first line and the second line is the first angle.
[0013] In a second aspect, the present invention provides a computer storage medium having a computer program stored thereon, characterized in that, when the program is executed by a processor, it implements the intelligent adjustment method for the height and angle of the display screen as described in the first aspect.
[0014] Thirdly, the present invention provides a terminal device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor, when executing the computer program, implements the intelligent adjustment method for display screen height and angle as described in the first aspect.
[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention can detect a user's sitting posture and identify the angle between the user's torso and neck. When the angle between the user's torso and neck is within a set threshold, it detects whether the user's line of sight and angle are within a comfortable range. If they are within the set range, no adjustment is made. If they are not within the comfortable range, the height and angle of the display screen in a comfortable state are calculated, and the display screen is adjusted to the corresponding height and angle. When the angle between the user's torso and neck is not within the set threshold, the height of the user's eyes when the torso and neck angle are adjusted to within the set threshold is first calculated. Based on the height of the eyes, the height and angle of the display screen when the user's line of sight is within a comfortable range are calculated, and the device is driven to adjust the display screen to the corresponding height and angle, thereby ensuring the health and comfort of the user's eyes and neck.

[0019] In the picture: 1. Workstation; 2. Personnel; 3. Display screen; 4. Camera. Detailed Implementation
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1: like Figure 1 and Figure 2 As shown, during the office process, person 2 sits at workstation 1, facing the display screen 3. If the height and / or angle of the display screen 3 is not suitable, it will cause discomfort to person 1's eyes and neck.
[0022] Please refer to Figure 3 This embodiment provides a method for intelligent adjustment of display screen height and angle, including the following steps: S0: Identify whether the person 2 at workstation 1 is using the display screen for work. If so, it is considered necessary to adjust the display screen and proceed to step S1; otherwise, it is considered unnecessary to adjust the display screen and the current height and angle of the display screen are maintained.
[0023] Since it is difficult to directly measure whether the display screen is in use, and people usually use the display screen with a keyboard or mouse, this solution uses mouse or keyboard usage recognition instead of display screen usage recognition.
[0024] The identification methods may include the following three: Method 1: Collect a top-down view of the workstation and use a trained model to detect hands, keyboard, and mouse. If the hands and keyboard overlap, and the hands and mouse also overlap, it is considered that the monitor is being used for work. This method can combine keyboard and mouse usage to identify whether the monitor is being used.
[0025] Method 2: Collect a top-down view of the workstation and use a trained model to detect hands and keyboards. If hands and keyboards overlap, it is considered that the monitor is being used for work. This method can be combined with keyboard usage to identify whether the monitor is being used.
[0026] Method 3: Collect a top-down view of the workstation and use a trained model to detect hands and mouse. If the hands and mouse overlap, it is considered that the monitor is being used for work. This method can be combined with mouse usage to identify whether the monitor is being used.
[0027] The reason why the above three methods use top-down images is that in normal work, the hands, keyboard, and mouse are all on the desktop. In the side view, even if the mouse or keyboard is not in use, there is still overlap and obstruction. Therefore, if side-down images are used, there is a great possibility of false detection. Top-down images, on the other hand, avoid this situation.
[0028] S1 detects the human posture of the person at the workstation, including the first angle between the neck and torso.
[0029] like Figure 2 As shown, the method for detecting the first angle between the neck and the torso is as follows: The side view image of personnel 2 is collected, and the head, shoulders, and hips in the side view image are identified using key points of the human skeleton. The head and shoulders are connected by a first line L1, and the shoulders and hips are connected by a second line L2. The angle between the first line L1 and the second line L2 is the first angle. .
[0030] S2, calculate the first included angle Is it within the set first threshold range [1, ]Inside. The size is set by the user, preferably 15°.
[0031] If the first included angle Within the set first threshold range [1, If the screen is positioned within the range of the neck, it is assumed that the person's neck is in a relatively comfortable position, and the display is adjusted to the first angle between the neck and torso. The following describes the height and angle at which the eyes are directly facing each other, and the specific method is as follows:
[0032] Get the first angle between the current neck and torso. Below, the second angle between the person's line of sight and the horizontal direction. Is it within the second threshold range [1, It is worth mentioning that, in this solution, the line of sight is the line connecting the human eye and the center point of the display screen.
[0033] Similarly, The size can also be set by the user, preferably 15°.
[0034] If the second included angle In the second threshold range [1, If the screen height is within the specified range, maintain the current screen height, and calculate the third angle formed by the line of sight and the screen. Is it within the third threshold range? , ]Inside,[ , The preferred angle is [85°, 95°]. If the third included angle... Within the third threshold range [ , If the current tilt angle of the display screen is suitable, keep the current tilt angle of the display screen unchanged; otherwise, if the current tilt angle of the display screen is not suitable, rotate the angle of the display screen so that the display screen and the line of sight form a third angle, preferably 90°.
[0035] If the second included angle If the display height is not within the second threshold range, then the display height is not suitable. Adjust the display height until the center point of the display is at the same height as your eyes, and rotate the display angle so that the display and the line of sight form a third angle.
[0036] If the first included angle Not within the set first threshold range [1, If the screen is positioned incorrectly, it indicates that the person's neck is in an uncomfortable position, placing a significant burden on the cervical spine. The screen will then be adjusted to the first angle between the neck and torso. The height and angle at which the viewer is directly facing the human eye when at a predetermined first angle, preferably 0° or the center value of a first threshold range. In this situation, the adjustment of the display screen causes it to shift, and guided in the opposite direction by the display screen, the neck of person 2 will adjust its posture accordingly.
[0037] The specific adjustment methods are as follows: Calculate the first angle between the neck and the torso. When adjusted to the set first angle, the height of the human eye and the line of sight;
[0038] Adjust the height of the display screen until the center point of the screen is at the same height as your eyes, and rotate the screen so that the screen and your line of sight form a third angle.
[0039] Example 2: This embodiment provides a computer storage medium storing a computer program, characterized in that, when the program is executed by a processor, it implements the intelligent adjustment method for the height and angle of the display screen as described in Embodiment 1.
[0040] Example 3: This embodiment provides a terminal device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. The feature is that when the processor executes the computer program, it implements the intelligent adjustment method for display screen height and angle as described in the first aspect.
[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
