Description

A method and mobile terminal for setting icon brightness based on user usage

technical field

The present invention relates to the field of display technology, in particular to a method and a mobile terminal for setting icon brightness based on user usage conditions.

Background technique

With the popularization of smart terminals, more and more applications (APP, Application) bring convenience to people's life, and the desktop of the user's smart terminal is the most direct entrance for us to use these APPs. However, as the number of APPs loaded on smart terminals increases, how a user can quickly find a certain APP has become an urgent problem to be solved.

At present, most smart terminals have the following two methods for dealing with similar problems: first, establish classification folders or classification areas, and classify and manage common applications; second, find required applications through background applications. For the first method, when a user wants to open a certain APP, he needs to first find the folder or storage area where the APP is located, and then find the APP to be opened from many similar APPs. This method of opening APP in the prior art requires the user to still remember the folders or locations corresponding to each APP, and the user experience is not good. For the second method, the application that the user wants to open must be used before and kept. In the cache, if the user has performed operations such as clearing the memory, power off or shutdown, the APP cannot be found through the background application.

In addition, due to the large number of current APPs, the similarity of the icons of the application programs is also increasing. When the icons of two application programs have a high degree of similarity, the user often needs to use the icon text displayed under the application program icons to accurately distinguish the icons. However, the icon text is often affected by the icon and the background, resulting in a problem of low recognition.

It can be seen that in the prior art, the app's icon recognition degree is not high and the icon text is easily disturbed are the reasons why the user cannot quickly find the icon that needs to be searched.

Contents of the invention

The invention provides a method and a mobile terminal for setting the brightness of icons based on the user's usage situation, which solves the problem in the prior art that the user cannot quickly find the icon to be searched due to the low recognition degree of the APP icon and the easy interference of the icon text.

In order to solve the above problems, an embodiment of the present invention provides a method for setting the brightness of an icon based on the usage of the user, including: setting the contrast level of the icon of the application according to the frequency of use of the application; calculating the gray value of the background area of the icon, The brightness of the icon is set according to the gray value and the contrast level, and the color of the icon text is set according to the color of the background area of the icon text.

Correspondingly, in order to solve the above problems, the embodiment of the present invention also provides a mobile terminal for setting the brightness of icons based on the user's usage, including: a contrast setting unit for setting the contrast level of the icon according to the frequency of use of the application program; and a color setting unit, configured to calculate the grayscale value of the icon background area, set the brightness of the icon according to the grayscale value and the contrast level of the icon set by the contrast setting unit, and, according to the icon text The color of the background area, sets the color of the icon text.

In the embodiment of the present invention, the contrast level of the icon of the application is set according to the frequency of use of the application, and then the gray value of the background area of the icon is calculated, and the color of the background area of the icon text is set. The color of the icon text, the brightness of the icon is set according to the gray value and the contrast level, for the icon of the application program frequently used by the user, by strengthening the contrast between the icon and the icon text and the brightness of the background area, the Displaying the icon facilitates the user to quickly find commonly used application programs among various applications with various names, and at the same time, improves user experience. Compared with the existing technology, there is no need to create a folder and enter the folder to search, and it is not affected by the memory clearing on starting the APP, and can quickly and efficiently present the APP icons frequently used by users.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

This embodiment provides a method for setting icon brightness based on the user's usage situation, as shown in Figure 1, the method includes:

Step 140, setting the contrast level of the icon of the application according to the usage frequency of the application;

Step 160, calculating the gray value of the background area of the icon, setting the brightness of the icon according to the gray value and the contrast level, and setting the icon text according to the color of the background area of the icon text s color.

During specific implementation, the threshold sampling period can be set, and the number of times the user uses each application program within N consecutive threshold sampling periods can be recorded, and the average usage frequency of the application program within one threshold sampling period can be calculated, so as to realize the collection of the user's feedback on the application program. The frequency of use of the program; for icons of frequently used applications, set a higher contrast level, the higher the contrast level, the stronger the contrast between the brightness of the icon and the brightness of the background area of the icon; finally, by calculating the icon The grayscale value of the background area is used as a reference grayscale value, and the brightness of the icon of the application program and the color of the icon text are set in combination with the contrast level of the application program. N is a positive integer greater than 1.

In another specific embodiment of the present invention, as shown in FIG. 2 , before the step of setting the contrast level of the icon of the application according to the frequency of use of the application, the method further includes: the step 120 of calculating the frequency of use of the application ,

The step 120 further includes: performing a weighted average calculation on the usage times of the application program within N consecutive threshold sampling periods starting from the current time point to obtain the average usage frequency of the application program within one threshold sampling period, wherein , N is a positive integer greater than 1.

The present invention collects the number of times a user uses an application, calculates the frequency of use of each application by the user within a period of time, sets the contrast level of the icon of the application according to the frequency of use of the application, and then calculates The gray value of the background area of the icon, the brightness of the icon is set according to the gray value and the contrast level, and the color of the icon text is set according to the color of the background area of the icon text. For the icons of applications frequently used by users, the icon is highlighted by enhancing the contrast between the icon and the brightness of the surrounding environment, so that users can quickly find commonly used applications among various applications, improve the use efficiency of the device, and further Improved user experience.

In a preferred embodiment of the present invention, the threshold sampling period is preset, and the continuous N threshold sampling periods are set with cycle weights from low to high in chronological order, and each threshold sampling period in the N continuous threshold sampling periods The period in turn includes a plurality of sub-threshold sampling periods. The mobile terminal will record the number of times the user uses any application during N consecutive threshold sampling periods. For example, when the user clicks the icon of the application on the desktop to start the application, the usage count of the application is increased by 1.

The step of calculating the usage frequency of the application program further includes: according to the set cycle weight, perform weighted average calculation on the usage times of the application program in N consecutive threshold sampling periods starting from the current time point forward, to obtain the The application program averages the usage frequency within a threshold sampling period, and N is a positive integer greater than 1; among them,

The number of times the application is used in the first threshold sampling period forward from the current time point is the sum of the weighted average of the number of times the application is used in all sub-threshold sampling periods in the threshold sampling period, starting from the current time point forward The multiple sub-threshold sampling periods in the first threshold sampling period are set with sub-sampling period weights from low to high in chronological order;

The number of times the application is used in the Mth threshold sampling period forward from the current time point is the sum of the number of times the application is used in all sub-threshold sampling periods within the threshold sampling period, M is a positive integer greater than 1 and less than or equal to N .

The technical solution of this embodiment will be described in detail below by taking the sub-threshold sampling period as 1 week, the threshold sampling period as 1 month, 4 weeks per month, and 12 consecutive weeks of continuous collection as an example. In this embodiment, N is equal to 3, and M is equal to 2 or 3.

From the first time each application was used, the number of times each application was clicked from the desktop to enter each application was recorded every week for 12 consecutive weeks. The following table is the recorded usage data of an application in 12 weeks. Week 01 represents the week closest to the current time, and week 12 represents the week farthest from the current time:

week number 01 02 03 04 05 06 07 08 09 10 11 12 frequency 20 20 30 20 30 40 30 40 30 40 40 50

Divide the obtained 12 consecutive weeks of usage times data into 3 months in chronological order, and the last sub-threshold sampling period is the closest to the current time point, that is, weeks 01, 02, 03, and 04 are the closest to the current time. The first month that is close; Weeks 05, 06, 07, and 08 are the second month from the current time; Weeks 09, 10, 11, and 12 are the third month from the current time. The number of usage data in each month is set with a corresponding cycle weight, and the cycle weight of the later months gradually increases. For example, the cycle weight of the first month is 60%, and the cycle weight of the second month is 30%. The cycle weight for the third month is 10%. The frequency calculation weight of the usage times in each week in the second month and the third month is equal to the cycle weight of the month, that is: the frequency calculation weight of the usage times in the 09th, 10th, 11th and 12th weeks is 10%; , 06, 07, 08 week frequency calculation weight of usage times is 30%. For the first month, further set the sub-sampling period weights from low to high for the usage times of each week in the month according to the order of time. For example, the number of uses in week 04 has a subsampling weight of 10%, the number of uses in week 03 has a subsampling weight of 20%, the number of uses in week 02 has a subsampling weight of 30%, and the number of uses in week 01 The subsampling period weights 40%.

Then, according to the number of times of using any app in the above 12 consecutive weeks, calculate the number of times the app is used in each month, and then calculate the monthly usage of the app in the 12 consecutive weeks (that is, 3 months) by weighted summation average frequency of use. First, calculate the number of times the application was used for the first month. The first month is the first threshold sampling period from the current time point forward, and the usage times of the application in the first threshold sampling period from the current time point forward are all sub-threshold sampling periods in the threshold sampling period The weighted average of the usage times of the application in the period is summed. The weighted sum of the times per week in the first month is used to obtain the weekly average times of use of the application in the first threshold sampling period forward from the current time point: W1=20×40%+20×30 %+30×20%+20×10%=22 times; then, multiply the average number of times per week in the first month by 4 as the number of times T ₃ used in the first month, that is, T ₃ =W1×4=22 ×4=88, that is, the number of times the application program is used in the first threshold sampling period from the current time point forward. Then, calculate the number of times the application is used in the Mth threshold sampling period from the current time point forward, that is, the number of times T2 of the application used in the _second month and the number of times T2 of the application used in the third month in this embodiment times T ₁ . The usage times of the application program in the Mth threshold sampling period forward from the current time point is the sum of the usage times of the application program in all sub-threshold sampling periods in the threshold sampling period. Wherein, M is a positive integer greater than 1 and less than or equal to N, that is, M does not include the first month closest to the current time. That is, T ₂ =30+40+30+40=140, T ₁ =30+40+40+50=160. Finally, the monthly usage times are weighted and summed to obtain the average usage times in each month within three months, as shown in the following formula: M1=T ₃ ×60%+T ₂ ×30%+T ₁ ×10%= 110.8.

According to the above method, the average number of times each application is used in each threshold sampling period within N consecutive threshold sampling periods can be calculated, that is, the frequency of use of each application. During specific implementation, other values may be set for the above-mentioned threshold sampling period and sub-threshold sampling period, and the frequency calculation weight may not be further set for the number of times of use per week in the first month, or set for each threshold sampling period and each sub-threshold sampling period Other weights can solve the problem of collecting the frequency of users using the application. The embodiment of the present invention is only a preferred embodiment. By setting a higher frequency calculation weight for recently used data, it is possible to more accurately analyze the user's usage, thereby more accurately setting the brightness of the application program, and improving user experience.

According to the color of the background area of the icon text, setting the color of the icon text includes: determining the average gray value of the background area of the icon text; according to the corresponding relationship between the preset average gray value and the icon text color, determining the icon The color of the text; set the color of the icon text. A reference gray value can be set. When the average gray value of the background area is lower than the reference gray value, it means that the background is relatively light, and the color of the icon text can be dark; when the average gray value of the background area is higher than When referring to the gray value, it indicates that the background is dark, and the color of the icon text can be light. The reference gray value can be set to 180. When the average gray value of the background area is 30, the gray value of the icon text can be any color greater than 180; when the average gray value of the background area is 200, the icon The gray value of the text can be any color less than 180. For example, if the background area is black, the icon text can be light-colored text such as light yellow or light blue. Set a light color list, the light color list includes a variety of colors with a gray value greater than 180, such as yellow, blue, green, etc.; set a dark color list, the dark list includes a variety of colors with a gray value less than 180 Color, such as black, purple, red, etc. The colors in the light list or dark list can be selected randomly, as long as the icon text and wallpaper can be effectively distinguished by human eyes. Effectively, when the icon similarity is large, the user can quickly determine the application icon to be searched through the icon text. In another specific embodiment of the present invention, the above-mentioned setting of the contrast level of the icon of the application program according to the frequency of use of the application program further includes: dividing all the application programs into a threshold number of Contrast level, setting the contrast level proportional to the usage frequency of the application program for the icon of the application program. The number of thresholds and contrast levels can be set in advance. For example, when the number of thresholds is 4, all applications are divided into 4 contrast levels in order of frequency of use from high to low, which are 1 to 4, and level 4 is the highest contrast level. The higher the contrast level, the greater the difference between the brightness of the icon and the brightness of the background area. For all applications, they are divided into groups with the same number of contrast levels as the number of contrast levels after being arranged in descending order of the collected usage frequency, that is, 4 groups, and each group of applications corresponds to a contrast level. For groups with higher usage frequency, the corresponding contrast level is higher. The above-mentioned threshold number can be set according to the number of applications on the mobile terminal and user experience. For example, if the mobile terminal has 20 applications, in order to display application icons more prominently, the threshold number can be set to 4, and each contrast level Contains 5 applications; if the mobile terminal has 10 applications, the threshold number can be set to 3. Identify the application's contrast level by adding a label to the application's properties.

By setting the contrast level of the threshold value, the brightness of the icon of the application program is displayed in different levels, which is convenient for the user to classify and find the application program according to the usage habits, and can also ensure the consistency of the brightness of the icon display.

The calculating the grayscale value of the background area of the icon, and setting the brightness of the icon according to the grayscale value and the contrast level include: calculating the grayscale value of the background area of the icon; when the grayscale When the value is higher than the threshold grayscale, the brightness of the icon is reduced according to the contrast level; when the grayscale value is lower than the threshold grayscale, the brightness of the icon is increased according to the contrast level. Setting the threshold grayscale, according to the contrast between the grayscale value of the background area of the icon and the threshold grayscale, and adjusting the brightness of the icon according to the contrast level, can allow users to better identify commonly used application icons.

During specific implementation, the background area of the icon is: take the border of the icon as the inner boundary, expand the inner boundary outwards by a distance to form an outer boundary, and enclose the area surrounded by the inner boundary and the outer boundary background area. The scheme of determining the designated area around the icon will be described in detail below in conjunction with FIG. 3 . Taking the icon 6 in Fig. 3 as an example, the inner boundary 301 of the icon 6 is extended outwards by a distance along the four directions of up, down, left and right respectively to form an outer boundary 302, and the inner boundary 301 and the outer boundary The oblique area 303 surrounded by 302 serves as the background area of the icon 6 . The distance can be determined according to specific needs, for example, it can be the difference between half the distance between the center of the icon 6 and the center of the icon 7 and half the side length of the icon 6; it can also be the distance between the center of the icon 6 and the center of the icon 8. The difference between the distance between them and the side length of the icon 6.

When determining the background area of the icon, if the background area exceeds the range of the desktop, the background area is reduced to the overlapping area of the background area and the desktop.

The operating system of the mobile terminal (such as a mobile phone) stores a database of desktops, and the display positions of the icons of various application programs can be obtained by calling the interface of the operating system to query the database of the standby desktop. The database of the standby desktop also records the number of desktop application icons and the size of the icons. After obtaining the position and size of any application program icon through the interface of the operating system, the screen coordinates of the specified area around the icon determined in the preceding embodiments can be easily calculated by using the existing technology.

The specific method for calculating the gray value of the background area of the icon is as follows: In the embodiment of the present invention, the background of the icon refers to the desktop wallpaper, and the background area of the icon refers to the corresponding area on the wallpaper. The information of the desktop wallpaper will be recorded in the database of the standby desktop. To calculate the grayscale value of the icon background area, first calculate the mean value of the color value of the wallpaper in the icon background area to obtain a hexadecimal color value similar to #FF080808; then, calculate the grayscale value of this color value For colorful wallpapers. If the original color of a certain point is RGB (R, G, B), the gray value of a certain point on the wallpaper can be calculated using the formula R×0.3+G×0.59+B×0.11 of the floating point algorithm.

The specific method for calculating the gray value of the wallpaper in the background area can be the method for calculating the gray value of the picture in the prior art, which is not limited in the present invention, and will not be repeated in the embodiments of the present invention. The calculated grayscale value of the background area of the icon is a value between 0 and 255, and then compare the calculated grayscale value with the threshold grayscale, and when the grayscale value is higher than the threshold grayscale When , the brightness of the icon is reduced according to the contrast level; when the grayscale value is lower than the threshold grayscale, the brightness of the icon is increased according to the contrast level.

During specific implementation, when the grayscale value is less than a threshold grayscale, it is determined that the background area of the icon is dark; when the grayscale value is greater than the threshold grayscale, it is determined that the background area of the icon is light color. The threshold grayscale is set according to actual needs, usually 180. When the background area of the icon is dark, determine the step brightness values corresponding to the contrast level one by one, each step brightness value is greater than the threshold brightness, set the brightness value of the icon to the step corresponding to the contrast level of the icon Brightness value. When the background area of the icon is light-colored, determine the step brightness value corresponding to the contrast level one by one, each step brightness value is less than the threshold brightness, set the brightness value of the icon to the step corresponding to the contrast level of the icon Brightness value. The difference between the brightness values of each step is greater than the step threshold. The step threshold is based on the obvious difference that human eyes can perceive, for example, it can be set to 20. Wherein, the threshold brightness is determined according to actual conditions, which is not limited in the present invention.

In another specific implementation, a brightness value is preset, and when the background area of the icon is dark, read the current icon brightness value, and increase the brightness value of the corresponding multiple of the contrast level; when the background area of the icon When it is a light color, read the current icon brightness value and reduce the brightness value by the corresponding multiple of the contrast level. Wherein, the brightness value is determined according to actual conditions, which is not limited in the present invention. By calling the interface of the operating system for drawing desktop icons, specifying the brightness parameters of the icons, and redrawing the icons, the display brightness of the icons can be changed.

In yet another specific embodiment of the present invention, each icon may be overlaid with a view whose light transmission degree can be changed, and the view is used to display a bitmap matching the size of the icon. When the background area of the icon is dark, determine the step brightness value corresponding to the contrast level one by one, each step brightness value is greater than the threshold brightness, set the brightness value of the bitmap above the bitmap to be the same as the icon The contrast level corresponds to the ladder brightness value. When the background area of the icon is light, the dark color of the icon can be easily recognized. At this time, determine the step brightness values corresponding to the contrast level one by one, each step brightness value is less than the threshold brightness, and set the brightness value of the bitmap on the icon to the step brightness value corresponding to the contrast level of the icon. By changing the light transmittance of the translucent bitmap on the icon, the display brightness of the icon can be changed, making it easier for the user to quickly find commonly used applications from the comparison with the background.

According to the color of the background area of the icon text, setting the color of the icon text is consistent with the foregoing content, and will not be repeated here.

The database of the desktop can be stored in the operating system of the mobile terminal (such as a mobile phone), and the display position and the length of the icon text of each application program can be obtained by calling the interface of the operating system to query the database of the standby desktop. During specific implementation, the position of the icon text of any application program is obtained through the interface of the operating system, and then the background area of the icon text is determined according to the length of the icon text.

The average gray value of the background area of the icon text can be calculated by using the method for calculating the average gray value of the image in the prior art, and the present application will not repeat it here. Since the background area of the icon text is usually within the background area of the icon, the gray value of the background area of the icon can also be used as the average gray value of the background area of the icon text. In this application, the method for calculating the average gray value of the background area of the icon text is not limited to the floating-point algorithm. The color depth of the background area of the icon text can be determined according to the average gray value. In specific implementation, multiple gray level thresholds can be set to represent different color depths, and the corresponding relationship between different gray level thresholds and icon text colors can be established in advance. . For example, a grayscale threshold 180 is preset, and when the average grayscale value is less than the grayscale threshold, it is determined that the background area of the icon text is dark, and the color of the corresponding icon text can be yellow; When the average gray value is greater than the gray level threshold, it is determined that the background area of the icon text is light-colored, and the color of the corresponding icon text may be purple. The calculated average gray value of the background area is used to match the gray level threshold, and the color of the icon text corresponding to the successfully matched gray level threshold is determined. Then, by specifying the color parameter of the icon text, the color of the icon text can be changed.

The above-mentioned setting of the color of the icon text according to the color of the background area of the icon text includes: determining the color value of the background area of the icon text; Color; sets the color of the icon text.

For the specific method of determining the background area of the icon text, refer to the description of the previous embodiments, which will not be repeated here. The average RGB component of each pixel in the background area of the icon text can be determined through the image recognition method in the prior art, and the color value of the background area can be further determined. The color of the chart text is determined according to the pre-established correspondence between the background color and the icon text color. For example, the corresponding relationship between the background color and the icon text color can be: the background color is purple, and the corresponding icon text color is yellow; the background color is black, and the corresponding icon text color is white. Then, calling the interface of the operating system for drawing desktop icons, specifying the color parameters of the icon text, and redrawing the icon can change the color of the icon text.

In the embodiment of the present invention, firstly, the gray value in the background area of the icon of the application program is calculated, and the background is a wallpaper. And taking the grayscale value of the background area of the icon of the application program as a reference, according to the contrast level of the icon, the brightness of the icon is correspondingly set. When the grayscale value of the background area of the icon of the application program is higher than the threshold grayscale, it is determined that the background area of the icon of the application program is light, and then the brightness of the icon is reduced according to the contrast level. The higher the contrast level, the more the brightness of the icon is reduced. When the grayscale value in the background area of the icon of the application program is lower than the threshold grayscale, it is determined that the background area of the icon of the application program is dark, and then the brightness of the icon is increased according to the contrast level. The higher the contrast level, the more the brightness of the icon is increased. The icon after resetting the brightness forms a strong contrast with the background of the icon, which plays a prominent role.

In another preferred embodiment of the present invention, as shown in FIG. 4, in the calculation of the gray value of the background area of the icon, the brightness of the icon is set according to the gray value and the contrast level, and After the step of setting the color of the icon text according to the color of the background area of the icon text, it also includes:

Step 180, detecting a trigger event for updating the brightness of the icon.

When the trigger event is detected, jump to step 120, and perform other steps after step 120 repeatedly. Repeat the step of calculating the frequency of use of the application to update the frequency of use; set the contrast level of the icon of the application according to the frequency of use of the application; calculate the gray value of the background area of the icon, and calculate the gray value according to the gray value and the contrast The level sets the brightness of the icon, and sets the color of the icon text according to the color of the background area of the icon text.

In the actual implementation of the present invention, various trigger events for updating the brightness of the icon can be set, for example, one or more of: the user performs a predetermined touch gesture, the user resets the wallpaper, and the time reaches the update cycle, and the like.

In a specific embodiment of the present invention, a user's preset touch gesture on the touch screen is detected, and when the touch gesture is detected, it is determined that there is a trigger event for updating the brightness of the icon. The preset touch gesture may be sliding two fingers to the right on the touch screen, touching a position without icons on the desktop for a long time, and the like.

In another specific embodiment of the present invention, the user's operation of changing the wallpaper is detected in real time, and when the user changes the wallpaper, it is determined that there is a trigger event for updating the brightness of the icon.

In another specific embodiment of the present invention, an update period of the icon brightness is set, and the timing is started until the last update of the icon brightness or the first entry into the desktop. event.

During specific implementation, the above three trigger events may be detected sequentially, or only one or two of the trigger events may be detected according to settings.

When a trigger event for updating the brightness of the icon is detected, the brightness of the application icon is reset. Repeat the step of calculating the frequency of use of the application to update the frequency of use; set the contrast level of the icon of the application according to the frequency of use of the application; calculate the gray value of the background area of the icon, and according to the gray value The brightness of the icon is set with the contrast level, and the color of the icon text is set according to the color of the background area of the icon text.

When the trigger event is detected, the usage frequency and contrast level are recalculated for all icons, and the icon brightness and icon text color of all applications are updated. Because the gray value of the background area of each icon is different, when setting the brightness and the color of the icon text, set it separately for each icon.

By detecting the trigger event for updating the brightness of the icon, the brightness of the icon can be updated in time, and the brightness of the icon can be triggered to update the brightness of the icon according to the user's initiative, which further improves the user experience.

Correspondingly, the embodiment of the present invention also discloses a mobile terminal for setting icon brightness based on user usage, as shown in FIG. 5 , including:
