Description

Technical Field

[0001] The present invention relates to the technical field of large-screen multimedia display control, and in particular to a large-screen multimedia display control system based on a domain architecture. Background Art

[0002] With the continuous development of multimedia technology, large-screen displays are being used more and more widely in various occasions, such as exhibition halls, conference rooms, shopping malls, etc. However, traditional large-screen display systems usually adopt a centralized control method, concentrating all display content on one or a few controllers for control, which cannot meet diverse application needs. The large-screen display system based on domain architecture can divide the large-screen display area into multiple independently controlled domains, each equipped with an independent controller and display screen. By dividing the large-screen display content into multiple independent small-screen display areas, the system complexity and failure rate are reduced, and the display effect and user experience are improved.

[0003] The existing large-screen multimedia display control method still has the following problems: 1. When adjusting and controlling the display resolution of each split-screen area corresponding to the target large screen, the initial resolution of the multimedia material, the screen aspect ratio and the screen physical resolution are not considered at the same time. The impact of the comprehensive display resolution of each split-screen area may cause image blur, loss of details, color distortion and other problems, seriously affecting the display quality, and may lead to a waste of screen resources. Some areas cannot be fully utilized, affecting the user's viewing experience.

[0004] 2. Currently, the display brightness of each split-screen area corresponding to the target large screen is adjusted and controlled mainly through manual adjustment by users, without comprehensive intelligent adjustment based on the ambient light intensity and the screen brightness that is comfortable for the human eye. When the display brightness is too high or too low, the user may not be able to see the screen content clearly, or may experience discomfort such as glare and fatigue. Maintaining excessively high brightness for a long time will accelerate the wear and aging of the large screen, thereby reducing the service life of the device.

[0005] 3. Currently, when the target large screen in the target exhibition hall is in the split-screen interactive function, the interactive screen corresponding to the interactive personnel is determined by their standing position, and the interactive personnel cannot independently select the interactive screen. If the interactive personnel feel that they cannot freely choose the interactive screen, they may feel that their participation is reduced and their enthusiasm for interaction is reduced, which may affect the interactive effect and user experience of the exhibition hall. At the same time, the exhibition hall may not be able to provide a personalized service experience and cannot meet the specific needs of different users. Summary of the Invention

[0006] In view of this, in order to solve the problems raised in the above background technology, a large-screen multimedia display control system based on domain architecture is proposed.

[0007] The objectives of the present invention can be achieved through the following technical solutions: The present invention provides a large-screen multimedia display control system based on a domain architecture, including: a resolution rationality analysis module, which is used to obtain the aspect ratio, physical resolution and current display resolution of each split-screen area corresponding to the target large screen when the target large screen in the target exhibition hall is in the split-screen display function, collect the multimedia materials corresponding to each split-screen area uploaded by the user, and obtain the initial resolution of the multimedia materials corresponding to each split-screen area, and analyze the rationality of the display resolution of each split-screen area corresponding to the target large screen.

[0008] The display resolution control module is used to record the split-screen area as a resolution-to-be-adjusted area when the display resolution rationality of a target large screen corresponding to a split-screen area is less than the display resolution rationality of a set reference, and confirm the display resolution to be adjusted of each resolution-to-be-adjusted area.

[0009] The brightness rationality analysis module is used to collect the light intensity of the current environment of the target large screen, and collect the current display brightness of each split-screen area corresponding to the target large screen, and analyze the display brightness rationality of each split-screen area corresponding to the target large screen.

[0010] The display brightness control module is used to record the split-screen area as a brightness-to-be-adjusted area when the display brightness rationality of a split-screen area corresponding to the target large screen is less than the display brightness rationality of a set reference, and confirm the display brightness to be adjusted of each brightness-to-be-adjusted area.

[0011] The interactive screen adjustment control module is used to obtain the interactive screens in the target large screen and the standing positions of the interactive personnel on the ground when the target large screen in the target exhibition hall is in the split-screen interactive function. When each interactive personnel stands at the corresponding standing position to select an interactive screen, the interactive screen selected by each interactive personnel is confirmed and recorded as the interactive screen selected by each interactive personnel. The image of each interactive personnel is collected and the position of the interactive screen in the target large screen is adjusted.

[0012] The database is used to store the appropriate display resolution corresponding to the initial resolution of each multimedia material, each screen aspect ratio and each screen physical resolution, store the appropriate screen brightness corresponding to each light intensity, store the comfortable screen brightness corresponding to the human eye, store the optimal screen brightness corresponding to the rationality of each display brightness, and store the comfortable sight elevation angle range corresponding to the interactive personnel.

[0013] Specifically, the analysis of the rationality of the display resolution of each split-screen area corresponding to the target large screen is as follows: A1, based on the aspect ratio, physical resolution and current display resolution of each split-screen area corresponding to the target large screen and the initial resolution of the multimedia material displayed in each split-screen area, calculate the comprehensive display resolution χ of each split-screen area corresponding to the target large screen. i, where i represents the number of the split-screen area, i=1,2,...,n.

[0014] A2. The current display resolution of each split-screen area corresponding to the target large screen is recorded as χ 当 .

[0015] A3. Calculate the reasonableness of the display resolution of each split-screen area corresponding to the target large screen δ i , Here, Δχ represents the display resolution deviation of the setting reference.

[0016] Specifically, the calculation process of the comprehensive display resolution of each split-screen area corresponding to the target large screen is as follows: B1, matching and comparing the initial resolution of the multimedia material displayed in each split-screen area with the appropriate display resolution corresponding to the initial resolution of each multimedia material stored in the database, and obtaining the appropriate display resolution corresponding to the initial resolution of the multimedia material in each split-screen area, which is recorded as

[0017] B2. Match and compare the aspect ratio and physical resolution of each split-screen area of ​​the target large screen with the appropriate display resolutions corresponding to each screen aspect ratio and each screen physical resolution stored in the database, and obtain the appropriate display resolutions corresponding to each split-screen area at the screen aspect ratio level and the screen physical resolution level, and record them as and

[0018] B3. Calculate the comprehensive display resolution χ of each split-screen area corresponding to the target large screen. i , Among them, a1, a2 and a3 respectively represent the weights of the comprehensive display resolution evaluation corresponding to the set initial resolution level of multimedia materials, screen aspect ratio level and screen physical resolution level.

[0019] Specifically, the method for confirming the display resolution to be adjusted of each resolution-to-be-adjusted area is: filtering out the comprehensive display resolution of each resolution-to-be-adjusted area from the comprehensive display resolution of each split-screen area corresponding to the target large screen, and using it as the display resolution to be adjusted of each resolution-to-be-adjusted area.

[0020] Specifically, the analysis of the rationality of the display brightness of each split-screen area corresponding to the target large screen is as follows: C1. Match and compare the light intensity of the current environment of the target large screen with the appropriate screen brightness corresponding to each light intensity stored in the database, and obtain the appropriate screen brightness corresponding to the light intensity of the current environment of the target large screen, and record it as ε 光 .

[0021] C2. Record the current display brightness of each split-screen area corresponding to the target large screen as

[0022] C3. Extract the comfortable screen brightness corresponding to the human eye from the database and record it as ε 眼 .

[0023] C4. Calculate the reasonableness of the display brightness of each split-screen area corresponding to the target large screen Among them, Δε′ and Δε″ respectively represent the screen brightness deviation at the set reference light level and the screen brightness deviation at the human eye comfort level, and a4 and a5 respectively represent the weights of the screen brightness deviation at the set light level and the screen brightness deviation at the human eye comfort level corresponding to the display brightness rationality evaluation.

[0024] Specifically, the method for confirming the display brightness to be adjusted of each brightness-adjusted area is: filtering out the display brightness rationality of each brightness-adjusted area from the display brightness rationality of each split-screen area corresponding to the target large screen, matching and comparing the display brightness rationality of each brightness-adjusted area with the optimal screen brightness corresponding to each display brightness rationality stored in the database, obtaining the optimal screen brightness of each brightness-adjusted area, and using it as the display brightness to be adjusted of each brightness-adjusted area.

[0025] Specifically, the position of the interactive screen in the target large screen is adjusted, and the specific adjustment process is: D1. The eye position of each interactive person is located from the image collected from each interactive person, and the center point position of the interactive screen selected by each interactive person is located at the same time, and the eye position of each interactive person is connected with the center point position of the corresponding selected interactive screen to obtain the corresponding line of sight connection line of each interactive person.

[0026] D2. If the sight lines corresponding to the interactive personnel do not intersect, it indicates that the interactive personnel and the corresponding selected interactive screen are on the same side. Calculate the rationality of the sight elevation angle between the interactive personnel and the corresponding selected interactive screen. If the rationality of the sight elevation angle between an interactive personnel and the corresponding selected interactive screen is less than the set reference sight elevation angle rationality, it indicates that the position of the interactive personnel corresponding to the selected interactive screen is unreasonable. The interactive screen corresponding to the interactive personnel and the interactive screen below it on the same side are swapped.

[0027] D3. If the sight lines corresponding to the interactive persons intersect, the selected interactive screens corresponding to the intersecting sight lines are moved to the same side of the corresponding interactive persons. Then, the positions of the interactive screens are interchanged in the same way as when the sight lines corresponding to the interactive persons do not intersect. Similarly, the positions of the interactive screens are interchanged when the sight lines corresponding to the interactive persons intersect.

[0028] Specifically, the rationality of the elevation angle of sight between each interactive person and the corresponding selected interactive screen is calculated as follows: E1. The distance between the eyeball of each interactive person and the center point of the corresponding selected interactive screen is located from the image collected by each interactive person, and recorded as the sight distance of each interactive person, recorded as Where, j represents the number of the interacting person, j = 1, 2, ..., m.

[0029] E2. Locate the vertical distance between the center point of the interactive screen selected by each interactive person and the horizontal ground, and record it as

[0030] E3. Calculate the sight line elevation angle θ between each interactive person and the corresponding selected interactive screen j ,

[0031] E4. Compare the line of sight elevation angle between each interactive person and the corresponding selected interactive screen with the comfortable line of sight elevation angle range corresponding to the interactive person stored in the database. If the line of sight elevation angle between an interactive person and the corresponding selected interactive screen is within the comfortable line of sight elevation angle range, then the rationality of the line of sight elevation angle between the interactive person and the corresponding selected interactive screen is set to τ1; otherwise, the rationality of the line of sight elevation angle between the interactive person and the corresponding selected interactive screen is set to τ2.

[0032] E5. Based on the above, the rationality of the sight angle between each interactive person and the corresponding selected interactive screen is obtained. The value of is τ1 or τ2, where τ1>τ2.

[0033] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention analyzes the rationality of the display resolution of each split-screen area corresponding to the target large screen by combining the aspect ratio, physical resolution and current display resolution of each split-screen area corresponding to the target large screen and the initial resolution of the multimedia material, and confirms the display resolution to be adjusted for each resolution-to-be-adjusted area, thereby avoiding problems such as image blur, detail loss, color distortion, etc., improving the display quality of the large screen, avoiding waste of screen resources, improving the full utilization of each split-screen area, and reducing the impact on the user's viewing experience.

[0034] (2) The present invention confirms the display brightness to be adjusted in each area to be adjusted by combining the light intensity of the environment and the screen brightness that is comfortable for the human eye, thereby avoiding the situation where the display brightness is too high or too low, causing the user to not be able to see the screen content clearly, or feel glare, fatigue, or other discomfort. At the same time, the wear and aging rate of the large screen is reduced, thereby extending the service life of the device.

[0035] (3) The present invention improves the participation of the interactive personnel by confirming the interactive screen selected by each interactive personnel and adjusting the position of the interactive screen in the target large screen. At the same time, it mobilizes the interactive enthusiasm of the interactive personnel, ensures the interactive effect of the exhibition hall, and helps the exhibition hall provide personalized service experience, thereby meeting the specific needs of different users.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figure 1 As shown, the present invention provides a large-screen multimedia display control system based on a domain architecture, including: a resolution rationality analysis module, a display resolution control module, a brightness rationality analysis module, a display brightness control module, an interactive screen adjustment control module and a database.

[0042] The resolution rationality analysis module is connected to the display resolution control module, the brightness rationality analysis module is connected to the display brightness control module, and the resolution rationality analysis module, brightness rationality analysis module, display brightness control module and interactive screen adjustment control module are all connected to the database.

[0043] The resolution rationality analysis module is used to obtain the aspect ratio, physical resolution and current display resolution of each split-screen area corresponding to the target large screen when the target large screen in the target exhibition hall is in the split-screen display function, collect the multimedia materials corresponding to each split-screen area uploaded by the user, and obtain the initial resolution of the multimedia materials corresponding to each split-screen area, and analyze the rationality of the display resolution of each split-screen area corresponding to the target large screen.

[0044] It should be noted that the aspect ratio, physical resolution, current display resolution of each split-screen area corresponding to the target large screen and the initial resolution of the multimedia material can all be extracted from the background management system of the target large screen.

[0045] In a specific embodiment of the present invention, multimedia materials include but are not limited to pictures and videos.

[0046] In a specific embodiment of the present invention, the rationality of the display resolution of each split-screen area corresponding to the target large screen is analyzed. The specific analysis process is as follows: A1, based on the aspect ratio, physical resolution and current display resolution of each split-screen area corresponding to the target large screen and the initial resolution of the multimedia material displayed in each split-screen area, calculate the comprehensive display resolution χ of each split-screen area corresponding to the target large screen. i , where i represents the number of the split-screen area, i=1,2,...,n.

[0047] In a specific embodiment of the present invention, the calculation process of the comprehensive display resolution of each split-screen area corresponding to the target large screen is as follows: B1, the initial resolution of the multimedia material displayed in each split-screen area is matched and compared with the appropriate display resolution corresponding to the initial resolution of each multimedia material stored in the database, and the appropriate display resolution corresponding to the initial resolution of each split-screen area at the level of the multimedia material is obtained, which is recorded as

[0048] It should be noted that in order to ensure the best display effect, the display system will adjust according to the initial resolution of the multimedia material to adapt to the resolution of the display screen. Therefore, the initial resolution of the multimedia material needs to be considered when analyzing the comprehensive display resolution of each split-screen area.

[0049] B2. Match and compare the aspect ratio and physical resolution of each split-screen area of ​​the target large screen with the appropriate display resolutions corresponding to each screen aspect ratio and each screen physical resolution stored in the database, and obtain the appropriate display resolutions corresponding to each split-screen area at the screen aspect ratio level and the screen physical resolution level, and record them as and

[0050] It should be noted that the display itself has a fixed physical resolution, which is the highest resolution the screen can present. If the resolution of the input source exceeds the physical resolution of the display, the system may adopt different strategies, such as reduction, cropping, or interpolation, to adapt to the display. At the same time, large screens usually have a specific aspect ratio, that is, the ratio of the width to the height of the screen. Ensure that the aspect ratio of the input source matches the large screen to avoid image distortion or the appearance of black edges. Therefore, the aspect ratio and physical resolution factors need to be considered when analyzing the comprehensive display resolution of each split-screen area.

[0051] B3. Calculate the comprehensive display resolution χ of each split-screen area corresponding to the target large screen. i , Among them, a1, a2 and a3 respectively represent the weights of the comprehensive display resolution evaluation corresponding to the set initial resolution level of multimedia materials, screen aspect ratio level and screen physical resolution level.

[0052] In a specific embodiment of the present invention, the setting value of a1 is 30%, the setting value of a2 is 30%, and the setting value of a3 is 40%. It should be noted that the physical resolution is directly related to the display quality of the large screen. Selecting a large screen with high physical resolution can usually provide clearer images. Therefore, when analyzing the comprehensive display resolution of each split-screen area, the weight of the screen physical resolution level is slightly higher.

[0053] A2. The current display resolution of each split-screen area corresponding to the target large screen is recorded as χ 当 .

[0054] A3. Calculate the reasonableness of the display resolution of each split-screen area corresponding to the target large screen δ i , Here, Δχ represents the display resolution deviation of the setting reference.

[0055] The display resolution control module is used to record a split-screen area as a resolution-to-be-adjusted area when the display resolution rationality of a target large screen corresponding to a split-screen area is less than the display resolution rationality of a set reference, and to confirm the display resolution to be adjusted of each resolution-to-be-adjusted area.

[0056] In a specific embodiment of the present invention, the method for confirming the display resolution to be adjusted of each resolution-to-be-adjusted area is: filtering out the comprehensive display resolution of each resolution-to-be-adjusted area from the comprehensive display resolution of each split-screen area corresponding to the target large screen, and using it as the display resolution to be adjusted of each resolution-to-be-adjusted area.

[0057] The embodiment of the present invention analyzes the rationality of the display resolution of each split-screen area corresponding to the target large screen by combining the aspect ratio, physical resolution and current display resolution of each split-screen area corresponding to the target large screen and the initial resolution of the multimedia material, and confirms the display resolution to be adjusted for each area to be adjusted, thereby avoiding problems such as image blur, detail loss, color distortion, etc., improving the display quality of the large screen, avoiding waste of screen resources, improving the full utilization of each split-screen area, and reducing the impact on the user's viewing experience.

[0058] The brightness rationality analysis module is used to collect the light intensity of the current environment of the target large screen, collect the current display brightness of each split-screen area corresponding to the target large screen, and analyze the display brightness rationality of each split-screen area corresponding to the target large screen.

[0059] It should be noted that the light intensity of the target large screen's current environment is collected by a light meter placed in the target large screen's current environment, and the current display brightness of each split-screen area of ​​the target large screen can be collected from the target large screen's background management system.

[0060] In a specific embodiment of the present invention, the analysis of the rationality of the display brightness of each split-screen area corresponding to the target large screen is as follows: C1. Match and compare the light intensity of the current environment of the target large screen with the appropriate screen brightness corresponding to each light intensity stored in the database, and obtain the appropriate screen brightness corresponding to the light intensity of the current environment of the target large screen, and record it as ε 光 .

[0061] C2. Record the current display brightness of each split-screen area corresponding to the target large screen as

[0062] C3. Extract the comfortable screen brightness corresponding to the human eye from the database and record it as ε 眼 .

[0063] C4. Calculate the reasonableness of the display brightness of each split-screen area corresponding to the target large screen Among them, Δε′ and Δε″ respectively represent the screen brightness deviation at the set reference light level and the screen brightness deviation at the human eye comfort level, and a4 and a5 respectively represent the weights of the screen brightness deviation at the set light level and the screen brightness deviation at the human eye comfort level corresponding to the display brightness rationality evaluation.

[0064] In a specific embodiment of the present invention, the set value of a4 is 50%, and the set value of a5 is 50%.

[0065] The display brightness control module is used to record the split-screen area as a brightness-to-be-adjusted area when the display brightness rationality of a split-screen area corresponding to the target large screen is less than the display brightness rationality of a set reference, and confirm the display brightness to be adjusted of each brightness-to-be-adjusted area.

[0066] In a specific embodiment of the present invention, the method for confirming the display brightness to be adjusted of each brightness-to-be-adjusted area is: filtering out the display brightness rationality of each brightness-to-be-adjusted area from the display brightness rationality of each split-screen area corresponding to the target large screen, matching and comparing the display brightness rationality of each brightness-to-be-adjusted area with the optimal screen brightness corresponding to each display brightness rationality stored in the database, obtaining the optimal screen brightness of each brightness-to-be-adjusted area, and using it as the display brightness to be adjusted of each brightness-to-be-adjusted area.

[0067] The embodiment of the present invention confirms the display brightness to be adjusted for each area to be adjusted by combining the light intensity of the environment and the screen brightness that is comfortable for the human eye, thereby avoiding the situation where the display brightness is too high or too low, causing the user to not be able to see the screen content clearly, or feel glare, fatigue, and other discomfort. At the same time, it reduces the wear and aging rate of the large screen, thereby extending the service life of the device.

[0068] See also Figure 2 As shown, the interactive screen adjustment control module is used to obtain the interactive screens in the target large screen and the standing positions of the interactive personnel on the ground when the target large screen in the target exhibition hall is in the split-screen interactive function. When each interactive personnel stands at the corresponding standing position to select an interactive screen, the interactive screen selected by each interactive personnel is confirmed and recorded as the interactive screen corresponding to the selected interactive screen of each interactive personnel. The image of each interactive personnel is captured, and the position of the interactive screen in the target large screen is adjusted.

[0069] It should be noted that the method of confirming the interactive screen selected by each interactive person is: the infrared sensor placed in each interactive screen will capture the signal reflected by the eyeball and convert it into a data signal. The data signal can be transmitted to a computer for analysis and processing. Therefore, when each interactive person's eyes are fixed on a certain interactive screen, the interactive screen where the interactive person's eyes are fixed is regarded as the interactive screen selected by the interactive person. If the eyes of multiple interactive persons are fixed on a certain interactive screen at the same time, the interactive screen will be regarded as the interactive screen selected by the interactive person who first fixed his eyes on the interactive screen, and other interactive persons will be reminded that the interactive screen has been selected and please select other interactive screens.

[0070] It should also be noted that the images of the interacting persons are captured by a camera placed on the target large screen.

[0071] In a specific embodiment of the present invention, the position of the interactive screen in the target large screen is adjusted, and the specific adjustment process is: D1. The eye position of each interactive person is located from the image collected from each interactive person, and the center point position of the interactive screen selected by each interactive person is located at the same time, and the eye position of each interactive person is connected with the center point position of the corresponding selected interactive screen to obtain the corresponding line of sight connection line of each interactive person.

[0072] D2. If the sight lines corresponding to the interactive personnel do not intersect, it indicates that the interactive personnel and the corresponding selected interactive screen are on the same side. Calculate the rationality of the sight elevation angle between the interactive personnel and the corresponding selected interactive screen. If the rationality of the sight elevation angle between an interactive personnel and the corresponding selected interactive screen is less than the set reference sight elevation angle rationality, it indicates that the position of the interactive personnel corresponding to the selected interactive screen is unreasonable. The interactive screen corresponding to the interactive personnel and the interactive screen below it on the same side are swapped.

[0073] In a specific embodiment of the present invention, the rationality of the elevation angle of sight between each interactive person and the corresponding selected interactive screen is calculated as follows: E1. The distance between the eyeball of each interactive person and the center point of the corresponding selected interactive screen is located from the image collected by each interactive person, and recorded as the sight distance of each interactive person, recorded as Where, j represents the number of the interacting person, j = 1, 2, ..., m.

[0074] E2. Locate the vertical distance between the center point of the interactive screen selected by each interactive person and the horizontal ground, and record it as

[0075] It should be noted that the sight distance of each interactive person and the vertical distance between the center point of the interactive screen selected by each interactive person and the horizontal ground are both collected by the installed distance sensors.

[0076] E3. Calculate the sight line elevation angle θ between each interactive person and the corresponding selected interactive screen j ,

[0077] E4. Compare the line of sight elevation angle between each interactive person and the corresponding selected interactive screen with the comfortable line of sight elevation angle range corresponding to the interactive person stored in the database. If the line of sight elevation angle between an interactive person and the corresponding selected interactive screen is within the comfortable line of sight elevation angle range, then the rationality of the line of sight elevation angle between the interactive person and the corresponding selected interactive screen is set to τ1; otherwise, the rationality of the line of sight elevation angle between the interactive person and the corresponding selected interactive screen is set to τ2.

[0078] E5. Based on the above, the rationality of the sight angle between each interactive person and the corresponding selected interactive screen is obtained. The value of is τ1 or τ2, where τ1>τ2.

[0079] In a specific embodiment of the present invention, the set value of τ1 is 1, and the set value of τ2 is 0.

[0080] D3. If the sight lines corresponding to the interactive persons intersect, the selected interactive screens corresponding to the intersecting sight lines are moved to the same side of the corresponding interactive persons. Then, the positions of the interactive screens are interchanged in the same way as when the sight lines corresponding to the interactive persons do not intersect. Similarly, the positions of the interactive screens are interchanged when the sight lines corresponding to the interactive persons intersect.

[0081] The embodiment of the present invention improves the participation of interactive personnel by confirming the interactive screen selected by each interactive personnel and adjusting the position of the interactive screen in the target large screen, while mobilizing the interactive enthusiasm of the interactive personnel, ensuring the interactive effect of the exhibition hall, and helping the exhibition hall provide personalized service experience, thereby meeting the specific needs of different users.

[0082] The database is used to store the appropriate display resolutions corresponding to the initial resolutions of various multimedia materials, the aspect ratios of various screens, and the physical resolutions of various screens, store the appropriate screen brightness corresponding to various light intensities, store the comfortable screen brightness corresponding to the human eye, store the optimal screen brightness corresponding to the rationality of various display brightnesses, and store the comfortable sight elevation angle ranges corresponding to the interactive personnel.

Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they should all fall within the scope of protection of the present invention.
