Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the technical solutions of the present application. All other embodiments obtained by a person skilled in the art without any inventive step based on the embodiments described in the present application are within the scope of the protection of the present application.
The terms "first" and "second" in the description and claims of the present application and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the term "comprises" and any variations thereof, which are intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The "plurality" in the present application may mean at least two, for example, two, three or more, and the embodiments of the present application are not limited.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.
As described above, depending on the distance between the user and the interactive smart tablet, a user farther away from the display screen may just see the content in the display screen at the same backlight brightness, but a nearby user may feel dazzling. Therefore, the prior art has a technical problem that the eyes of a near user cannot be protected while ensuring that a far user can clearly see the display content in a large screen.
For example, in the existing multimedia teaching, the use of large-screen teaching has become a development trend, and the content displayed on the large screen needs to be clearly displayed in a classroom to ensure that each student can see the teaching content clearly. Since the classroom is large, the brightness of the large screen cannot be too low to take care of students sitting in the back row. But for the teacher, due to the closer distance to the large screen. This brightness is too bright and is very unpleasant for the eye to write. After a class, the teacher cannot feedback that the eyes are not received, and the eyes of the teacher can be damaged after a long time, so that the eyesight of the teacher is influenced, and the contradiction between the requirements of back-row students and the requirements of the teacher on the screen brightness is caused.
In view of this, the inventor of the present application analyzes whether the student can see clearly the parameters displayed on the screen, and finds that whether to see clearly is not determined completely by the brightness, and the contrast between the display content such as handwriting and the display background may also have an influence on whether to see clearly the content on the screen. The embodiment of the application provides a display adjustment scheme, in which the position of a touch point of a user in a display screen can be determined by detecting the touch operation of the user on the display screen of an interactive intelligent tablet, that is, the position indicates that the user may write around the touch point or explain content around the touch point; furthermore, the backlight brightness of the display area around the touch point can be reduced, so that the stimulation degree of the display area to the eyes of the user is reduced, and the eyesight of the user is protected; meanwhile, the contrast between the display background and the display content in the display area can be enhanced, so that the vision of a user near the screen is protected, and other users far away from the screen can clearly see the content displayed in the display area.
After introducing the design concept of the embodiment of the present application, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present application can be applied, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application and are not limited. In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.
Please refer to fig. 1a, which is a schematic diagram of an application scenario. The application scenario includes an interactive smart tablet 101, a first user 102, and a second user 103. The interactive smart tablet 101 includes a distance detection module 1011, a display screen 1012, a touch detection module (not shown in fig. 1 a), and the like, where the distance detection module 1011 may be configured to detect a distance between a user and the interactive smart tablet, so as to determine whether the user approaches the interactive smart tablet; display screen 1012 may be used to display content that a user desires to be presented; the touch detection module may be configured to locate a position of a contact point 1013 that a user initially contacts the display screen 1012 when a touch operation of the user on the display screen 1012 is detected. The distance between the first user 102 and the interactive smart tablet 101 is closer than the distance between the second user 103 and the interactive smart tablet 101.
In the embodiment of the present application, the distance detection module 1011 may be a human infrared sensor, which is a sensor that can detect infrared radiation by using a physical effect exhibited by interaction between infrared radiation and a substance. Thus, the distance between the user and the display screen 1012 can be determined by detecting the infrared radiation of the user. For example, when the human body infrared sensor is used in a classroom, the human body infrared sensor with the distance of 1 meter and the angle of 120 degrees can be selected. Of course, other parameters of human body infrared sensing may be selected, and the embodiment of the present application is not particularly limited. Alternatively, the distance detection module may be another sensor such as an optical sensor.
In this embodiment, at least one distance detection module 1011 may be disposed in a corresponding area of the display screen 1012. When only one distance detection module is arranged, the distance detection module can be arranged at the center of the display screen 1012 of the interactive intelligent tablet, and the function of detecting that a user approaches the display screen 1012 can be realized. Referring to fig. 1B, when two distance detection modules are provided, assuming that the distance detection modules can be disposed at the position a and the position B of the lower portion of the display screen 1012, the display area that needs to reduce the backlight brightness corresponding to the contact point 1013 that the first user 102 initially touches the display screen 1012 is 1014. In this way, besides detecting the approach of the user, the left-right movement position of the user relative to the display screen 1012 can be judged, so that the movement direction of the display area 1014 needing to reduce the backlight brightness can be determined according to the movement direction of the user relative to the display screen 1012, and the accuracy of the display area needing to reduce the backlight brightness is improved. The display area 1014 may have any shape, and for convenience of description, the display area 1014 is illustrated as an elliptical area in fig. 1 b. How to determine the display area 1014 will be described in detail below, and will not be described in detail here.
In this embodiment of the application, the application scenario shown in fig. 1a may be a scenario in which a teacher teaches through an interactive smart tablet in a multimedia classroom, a scenario in which staff members in a conference room explain conference contents through the interactive smart tablet, or another scenario in which the interactive smart tablet needs to be used.
To further illustrate the application display scheme provided by the embodiments of the present application, the following detailed description is provided in conjunction with the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figures when the method is executed in an actual processing procedure or a device (for example, a parallel processor or an application environment of multi-thread processing).
Referring to fig. 2, a flowchart of a display adjustment method according to an embodiment of the present application is shown, where a specific flowchart of the display adjustment method in fig. 2 is described as follows:
step 201: the method comprises the steps of detecting touch operation of a user on a display screen, and determining the position of a first touch point of the user in initial contact with the display screen.
In the embodiment of the application, a user can touch the display screen through a finger or by means of some auxiliary tools, so that the interactive smart tablet can detect the touch operation of the user on the display screen, acquire touch information, and then position the first contact point of the user initially contacting the display screen according to the touch information. Specifically, when the position of the first touch point is located, a certain point in the display screen may be selected as an origin, for example, a point at the edge of the lower left corner of the display screen is selected as the origin, a coordinate system is established, and when the touch information of the first touch point where the user touches the display screen is detected, the position coordinate of the first touch point may be obtained through analysis.
Step 202: and determining a target display area according to a preset display area selection mode based on the position of the first contact.
In the embodiment of the present application, the target display area may be an area in which the line of sight of a user (such as the first user 102 in fig. 1 a) is concentrated in the display screen, the first user 102 may write in the target display area, or may explain content displayed in the target display area. For example, the teacher writes a board in the target display area, or the teacher is explaining a mathematical problem in the target display area. After the position of the first contact is determined, the target display area may be determined according to a preset display area selection manner, which specifically includes the following determination manners:
firstly, the position of a first contact point is taken as a center, and a display area within a preset radius range of the first contact point is determined as a target display area.
In this embodiment of the application, as shown in fig. 3, after the position of the first contact is determined, the first contact may be used as a center of a circle, and a circular area with a preset radius is selected as a target display area. The preset radius may be preset, and all users may correspond to the same preset radius, such as 40 cm, or different preset radii that are set first may correspond to different users, and may be specifically set according to the use habit of each user, for example, the preset radius corresponding to the first user is 40 cm, and the preset radius corresponding to the second user is 35 cm, and the like. Alternatively, after the first contact point is determined and before the target display area is determined, the user may select the size of the preset radius by himself, for example, the user may select the size of the preset radius by voice. Therefore, the user operation can be facilitated to a certain extent, and the use experience of the user is improved.
And secondly, selecting a display area with any shape from the first contact point and the second contact point as a target display area along the direction from the first contact point to the second contact point by taking the position of the first contact point as an initial position, wherein the second contact point is the contact point of the user contacting the displayed screen detected after being close to the first contact point.
In the embodiment of the application, the target display area can also be selected according to the habit of displaying the content by using the display screen and the writing habit of the user. Specifically, the position of the first contact point may be used as a starting position of the display area, and the target display area may be selected according to a user's use habit, writing habit, and the like. For example, as shown in fig. 4, taking the user writing on the display screen as an example, assuming that the user is used to write from left to right, the first contact point that the user initially touches the display screen is on the left of the second contact point that the user touches the display screen for the second time, so that the rectangular display area can be selected as the target display area along the direction of the second contact point with the first contact point as the starting position. Of course, the shape of the target display area may be a triangle, a quadrangle other than a rectangle, a pentagon, etc., and is not limited in particular.
Further, the target display area is determined according to the above manner, if it is detected that the user moves left and right in front of the display screen, after the position of the third contact point where the user contacts with the display screen exceeds the target display area, the target display area may be re-determined according to the position of the third contact point, that is, the target display area in the embodiment of the present application may move along with the movement of the user.
Step 203: the backlight brightness of the target display area is reduced, and the contrast of the display background and the display content in the target display area is enhanced.
In the embodiment of the present application, as described above, if the display condition of the display screen remains unchanged, when a user (e.g., the second user 103 in fig. 1 a) farther away from the display screen of the interactive smart tablet clearly sees the display content in the display screen, the backlight brightness of the display screen may be glaring for a user (e.g., the first user 102 in fig. 1 a) closer to the display screen, and if the user watches the glaring display screen for a long time, the eyesight of the user may be affected. Therefore, in order to avoid the backlight brightness stimulation of the display screen to the eyes of the user close to the display screen and protect the eyesight of the user, after the target display area required to be used by the user is determined, the backlight brightness of the target display area can be reduced, so that the backlight brightness of the target display area is milder, the eyes of the user cannot be stimulated, and the eyesight of the user is protected.
Meanwhile, in order to make the content displayed in the target display area clearly visible to the user far from the display screen, the contrast between the display background and the display content in the target display area may be increased. Contrast may refer to a measure of the different brightness levels between the brightest white and darkest black of the light and dark regions in the target display area, with a larger range representing a larger contrast and a smaller range representing a smaller contrast. Taking a blackboard writing written by a teacher as an example, the blackboard writing is displayed by black characters, the blackboard writing background is white, and the contrast between the blackboard writing background and the blackboard writing in the target display area is higher, so that the blackboard writing observed by a user is clearer. After the contrast is increased, on the basis of not affecting the user to clearly see the display content, the display content in the target display area can be highlighted in the whole display screen, the sight lines of other users can be attracted, the attention points of other users are concentrated in the target display area, and therefore the display efficiency of the display content in the target display area can be improved to a certain extent.
Alternatively, when the backlight brightness of the target display area is reduced, the same reduction value may be set for all users. For example, the backlight brightness of the display screen is divided into 10 levels from low to high, the current backlight brightness of the display screen is at the 9 th level, and after the target display area is determined, the backlight brightness in the target display area is reduced by 2 levels no matter who the user is, that is, the backlight brightness of the target display area is reduced to the 7 th level. Therefore, the stimulation of the backlight brightness in the target display area used by the user to the eyes of the user can be reduced, and the eyesight of the user is protected.
Alternatively, the backlight luminance reduction values of the target display regions corresponding to different users may be different. Specifically, different target backlight brightness suitable for the eyes of the user to watch can be set for different users according to the user information. Therefore, when the backlight brightness of the target display area is reduced, the user currently using the interactive smart tablet can be detected so as to obtain the user information of the user, wherein the user information can include the identity information, the eyesight condition, the eye health condition, the habitual display screen backlight brightness and the like of the user. And further, the target backlight brightness corresponding to the user can be determined according to the user information, wherein the target backlight brightness is the background brightness adapted to the eyes of the user, so that the backlight brightness of the target display area can be reduced to the target backlight brightness, the backlight brightness of the target display area is smaller than that of the first display area, and the first display area is a display area except the target display area in the display screen of the interactive intelligent panel. Therefore, on the basis of reducing the stimulation of the backlight brightness of the target display area used by the user to the eyes of the user and protecting the eyesight of the user, the backlight brightness adjustment of the target display area is more humanized, the reduced backlight brightness of the target display area better conforms to the use habit of the user, and the use experience of the user can be improved.
For example, assume that the current brightness of the display screen is 9 levels, the backlight brightness corresponding to the a user is 7 levels, the backlight brightness corresponding to the B user is 6 levels, and the backlight brightness corresponding to the C user is 8 levels. And determining that the user is the user B according to the acquired user information, and further reducing the backlight brightness of the target display area to the 6 th level so that the backlight brightness of the target display area is suitable for the user B and eyes of the user B are not stimulated.
Optionally, in this embodiment of the application, please refer to fig. 5, before detecting the touch operation of the user on the display screen, the distance between the user and the display screen of the interactive smart tablet may be detected by using the distance detection module 1011 shown in fig. 1a, and when detecting that the distance between the user and the display screen is smaller than the first threshold, the display screen may be controlled to start detecting the touch operation of the user on the display screen, that is, when the distance between the user and the display screen is greater than or equal to the first threshold, it indicates that no user needs to perform the touch operation on the display screen, and the display screen does not need to detect the touch operation of the user on the display screen, so that the power consumed by detecting the touch operation or other occupied resources may be saved.
Optionally, in this embodiment of the application, please continue to refer to fig. 5, after the contrast between the display background and the display content in the target display area is enhanced, a distance between the user and the display screen may be detected, and if the distance is greater than or equal to the second threshold, the backlight brightness of the target display area may be increased to the backlight brightness of the display area other than the target display area in the display screen. Therefore, the backlight brightness in the whole display screen is consistent, the displayed display effect is the same, the visual difference of a user is avoided, and the eye fatigue degree of the user is reduced.
Optionally, in this embodiment of the application, in order to enable a user farther away from the display screen to observe the display content in the target display area more clearly, the display content in the target display area may be enlarged according to a predetermined scale. For example, the display content in the target display area may be enlarged to 1.5 times the display content in the other display areas. For another example, if the display content in the target display area is a character and the font size is a font size of 14, the character can be enlarged to a font size of 18. Alternatively, if the display content in the target display area includes characters and graphics, only the character size of the characters in the display content may be enlarged, and the size of the graphics in the display content may be kept unchanged.
Therefore, by the method, the backlight brightness of the target display area corresponding to the user who will contact and use the display screen can be reduced, and the contrast of the display background and the display content in the target display area can be increased, namely, the local backlight brightness and the contrast of the display screen can be adjusted, so that the local area is not dazzled by the user at a close position, and the user at a far position can clearly see the local area. Therefore, the dazzling degree of the target display area to the near user can be reduced and the eyesight of the user can be protected while the content displayed in the target display area is watched by the far user is not influenced.
