Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for dynamically adjusting the brightness of the terminal screen provided by the embodiment of the application can be applied to an application environment shown in fig. 1, namely, the method is applied to a driving process, and a user can conveniently control a vehicle to move according to a route indicated by navigation. The terminal may be a vehicle machine (i.e., a vehicle-mounted terminal) in the vehicle 01, a mobile phone of a user, an iPad, or another intelligent terminal equipped with navigation software or having a navigation function, which is not limited in the embodiment of the present application.
The terminal can automatically adjust the brightness of the target screen based on whether the eyes of the user watch the target screen or not, so that the dynamic adjustment of the brightness of the target screen is realized, the manual intervention of the user is not needed, the dispersion of the attention of the user can be improved, the power consumption is reduced, the stimulation to the eyes of the user is reduced, and meanwhile, the potential safety hazard is favorably reduced.
The method for adjusting the brightness of the terminal screen provided by the embodiment of the present application is exemplarily described below with reference to fig. 2 to 4.
In one embodiment, as shown in fig. 2, a method for dynamically adjusting the brightness of a terminal screen provided in the embodiment of the present application may be applied in a scene of route navigation, for example, in a scene of vehicle navigation shown in fig. 1; the method can be executed by a terminal screen brightness adjusting device, can be realized in a software and/or hardware mode, and can be integrated on the electronic equipment. Taking the method applied to any terminal in fig. 1 as an example, the method includes the following steps.
And S110, determining the eye gazing direction of the user.
The eye gaze direction of the user can also be understood as the sight line direction of the user, and can be used for determining whether the attention of the user is focused on the target screen so as to adjust the brightness of the program target screen.
In particular, the terminal may determine the user eye gaze direction based on eye tracking technology or other means, which is not limited herein.
And S120, judging whether the user gazes at the target screen or not based on the gazing direction.
Based on the gazing direction of the user, the sight line falling point of the user, namely the intersection point of the sight line direction of the user and the plane where the target screen is located, can be determined. When the time that the sight line drop point is located in the target screen exceeds a time threshold, indicating that the user is watching the target screen; when the sight line falling point is positioned outside the target screen or the time that the sight line falling point is positioned in the target screen does not exceed (is less than or equal to) the time threshold, the user is indicated not to watch the target screen. Illustratively, when the user's gaze sweeps across the target screen and does not stay at the target screen, it is determined that the user is not gazing at the target screen.
The time threshold may be any value set according to the needs of the user, may be set autonomously by the user, or may be set and adjusted autonomously by the terminal based on the time required by the user to view the navigation route, which is not limited herein.
The plane of the target screen may be determined based on a reference point of the target screen, which may be, for example, a corner point, a center point, or a point within other contours of the target screen, and is not limited herein.
Specifically, a threshold corresponding to the contour (i.e., the boundary) of the target screen may be set in the terminal, and the position of the sight-line landing point may be compared with the threshold corresponding to the contour of the target screen to determine whether the user gazes at the target screen.
The threshold corresponding to the outline of the target screen may be a fixed value, a value that changes based on a position change of the target screen, or any value that is set according to a user's needs, and is not limited herein.
S130, under the condition that a user watches a target screen, keeping the brightness of the target screen as a first brightness; reducing the brightness of the target screen to a second brightness under the condition that the user does not watch the target screen; the second luminance is lower than the first luminance.
The first brightness, the second brightness, the third brightness, the fourth brightness and the certain brightness are parameters that can be used to represent screen brightness, and they can be represented by absolute brightness or relative brightness. For example, the absolute brightness may be a physically defined brightness; the relative brightness may be one of the luminances (e.g., the maximum luminance) as a reference, and the other luminances are normalized luminances based on the reference, which is not limited herein.
Based on this, the second luminance is lower than the first luminance, i.e., the first luminance is higher than the second luminance. For example, taking the first luminance as the reference, the first luminance may be 1; the second brightness may be 60%, 70%, or other percentage values based between 0 and 1, and is not limited herein.
In other embodiments, the first brightness, the second brightness, the third brightness, the fourth brightness, a certain brightness and other brightness may be any values set according to the needs of the user, and it is sufficient that the relative high-low relationship of the brightness in the present application is satisfied, which is not limited herein and will not be described in detail later.
Specifically, the terminal can keep the brightness of the target screen to be higher brightness when the user watches the target screen; when the user does not watch the target screen, the brightness of the target screen is reduced to be lower brightness, so that the dynamic adjustment of the brightness of the screen can be realized, manual intervention of the user is not needed, the problem of distracting the user can be solved, and potential safety hazards are reduced. Meanwhile, the brightness of the target screen can be reduced under the condition that a user does not watch the target screen by adjusting the brightness of the target screen, so that the power consumption can be reduced; and the stimulation to the eyes of the user is reduced, and the safety is improved.
In one embodiment, based on fig. 2 above, S110 may include:
an eyeball tracking technology is realized through an infrared positioner and a camera of the terminal so as to determine the eye gazing direction of a user.
When the eyes of the user look at a certain direction, a corresponding sight line direction, namely a corresponding watching direction, is formed. When the eyes of the user look at different directions, the eye parts have slight changes, and the changes correspond to the characteristics which can be extracted; these features are extracted by image capture or scanning, so that the eyeball is tracked, and the corresponding gaze direction is determined.
In this embodiment, the user does not need to wear additional equipment, and only needs to set up infrared locator and camera on the terminal, can realize tracking user's eyeball to confirm user's eyes and watch the direction. An eyeball tracking technology based on an infrared locator and a camera is a 'non-invasive' technology based on eye Video analysis (VOG), and the realization process is as follows: a beam of infrared light (such as near infrared light) and a camera of a camera are aligned with eyes of a user, the watching direction of the eyes of the user is deduced through analysis, namely back-end analysis, of the infrared light and a video collected by the camera, and the camera records the interaction process.
In other embodiments, other structures and corresponding principles may also be adopted to implement eye tracking, which are not described or limited herein.
In one embodiment, fig. 3 shows a flow of another method for dynamically adjusting the brightness of the screen of the terminal. On the basis of fig. 1, with reference to fig. 3, the method may comprise the following steps.
And S200, starting.
Namely, the flow of the screen brightness dynamic adjustment method is started. Taking the operation of the user on the terminal as an example, the step may include: and the user presses or clicks the corresponding function key to start the screen brightness dynamic adjustment function of the terminal. The function can be applied to terminal navigation process or other processes that the user watches the screen at irregular time, and is not limited herein.
S201, judging whether navigation is performed or not.
In the navigation state, the screen of the terminal usually displays a navigation route for the user to view. Based on this, the terminal may determine whether it is in the navigation state by detecting whether its screen displays the navigation route, for example.
If the terminal is not in the navigation state, that is, if the judgment result is no (N), executing S208; if the terminal is in the navigation state, i.e. the determination result is yes (Y), the following steps S202-S207 are executed.
In other embodiments, the dynamic screen brightness adjustment function of the terminal may also be started simultaneously with the start of the navigation function of the terminal, which is not limited herein.
In conjunction with the method illustrated in fig. 2, before S110, the method may further include: and determining that the terminal is in a navigation state.
Therefore, under the navigation state, the automatic dynamic adjustment of the terminal screen brightness can be realized, the manual intervention of a user is not needed, the stimulation to the eyes of the user is reduced while the user checks the navigation route, the dispersion to the attention of the user is reduced, the potential safety hazard is reduced, and the safety is improved.
S202, determining the eye gazing direction of the user through the infrared positioner and the camera.
Namely, an eyeball tracking technology is realized through an infrared locator and a camera in the terminal so as to determine the eye gazing direction of a user.
S203, judging whether the user watches the target screen.
In this embodiment, the target screen is a screen for displaying the navigation route, and may be a car screen, a mobile phone screen, an iPad screen, or another screen with a display function, which is not limited herein.
In this step, the terminal may determine whether the user 'S eyes are gazing at the target screen based on the user' S eye gazing direction determined in S202.
If the user watches the target screen, that is, if the determination result is yes (Y), performing the following S204; if the user does not watch the target screen, i.e. the determination result is no (N), the following S205-S207 are performed.
And S204, adjusting the brightness of the target screen to be normal brightness, and keeping the brightness for a certain time.
The normal brightness is the brightness which is convenient for a user to check the navigation route, and the certain time is the time which is satisfied for the user to check the navigation route. After keeping the normal brightness for a certain time, jumping to S201, so as to return to the step after the beginning, and during the navigation, the adjustment of the screen brightness can be realized based on the eye gazing direction of the user.
For example, the normal brightness may be similar to the first brightness in the above, and the low brightness in the following may be similar to the second brightness in the above. In other embodiments, the normal brightness and the low brightness may also be set to different brightness values from the first brightness and the second brightness, which may be set according to user requirements, and is not limited herein.
Illustratively, the "certain time" may be set by the user, and the target screen may be maintained at normal brightness for a period of time, for example, the time may be 1 second, so that the user can view the navigation route at a sufficient brightness.
In this step, the terminal maintains the brightness of the target screen at a normal brightness for a certain time, so that the user can view the navigation route.
In connection with the method illustrated in fig. 2, after S130, the method may further include:
acquiring a first duration for keeping the brightness of a target screen at a first brightness;
judging whether the first time length is equal to or greater than a first preset time length;
and returning to the navigation state when the first time length is equal to or greater than the first preset time length.
Specifically, under the condition that the user gazes at the target screen, the terminal keeps the brightness of the target screen to be the first brightness, and the duration of keeping the first brightness is equal to or longer than the first preset duration, so that the user can have a long enough time to view the navigation route under the enough brightness, and the user can conveniently and accurately obtain the route information.
The first preset time period may be 1s, 2s or other time periods, and may be set according to a requirement of a user, which is not limited herein. The following setting of the durations such as the second preset duration, the third preset duration, the fourth preset duration and the like is the same, and the setting may be any time length value according to the requirement of the user.
And S205, reducing the brightness of the target screen.
Wherein the reduction is to dim the brightness of the target screen based on the normal brightness.
Specifically, the terminal reduces the screen brightness to a certain brightness darker than the normal brightness, so that the low-power-consumption display screen can be maintained, the stimulation of the screen to the eyes of a user can be reduced, and the driving safety is favorably improved.
The "certain brightness" may be 60%, 70% of the normal brightness, or other brightness values lower than the normal brightness, which are set by a user, or randomly selected by the terminal, and is not limited herein.
Thereafter, the duration in which the low brightness is maintained for the target screen is monitored, i.e., S206 is performed.
And S206, judging whether the duration of maintaining the low brightness reaches a threshold value.
The low brightness is a certain brightness which is darker than the normal brightness after being adjusted in S205, and the threshold is a time length threshold which can be set by a user, and can be 1S, 2S or other time lengths, which is not limited herein. When the duration reaches the threshold value, the user does not watch the target screen for a long time, the brightness of the target screen can be continuously reduced, or the target screen is directly closed, so that the power consumption is reduced.
In the step, the terminal acquires the time length of the target screen at low brightness, judges whether the time length reaches a threshold value, and can determine whether the user does not watch the target screen for a long time.
If the duration of the low brightness of the target screen does not reach the threshold, that is, if the determination result is no (N), the process skips to S201 while maintaining the low brightness, so that the process can return to the step after the start, and the screen brightness can be adjusted based on the eye gazing direction of the user in the navigation process.
If the duration of the low brightness of the target screen reaches the threshold, namely the judgment result is yes (Y), the user does not watch the target screen for a long time, and the brightness of the target screen can be further reduced until the target screen is closed; or the target screen can be directly closed (see the following step S207), so that the power consumption can be further reduced, and the stimulation of the screen brightness to the eyes of the user can be reduced, thereby further improving the safety.
In connection with the method illustrated in fig. 2, after S130, the method may further include:
acquiring a second time length for keeping the brightness of the target screen at a second brightness;
judging whether the second time length is equal to or greater than a second preset time length or not;
under the condition that the second duration is greater than or equal to a second preset duration, closing the target screen or continuously reducing the brightness of the target screen to a third brightness; the third luminance is lower than the second luminance.
Specifically, in a case where the user does not look at the target screen, the terminal maintains the brightness of the target screen at the second brightness, at which time the brightness of the target screen has been reduced to a lower brightness. If the duration of the target screen maintaining the second brightness reaches the second preset duration, which indicates that the user does not watch the target screen for a long time, the target screen may be closed, or the brightness of the target screen may be continuously reduced to a third brightness.
Then, after the brightness of the target screen is reduced to the third brightness, the duration that the target screen is maintained at the third brightness may be continuously obtained, and when the duration reaches a duration threshold, the brightness of the target screen may be continuously reduced until the target screen is closed. In the process of reducing the brightness of the target screen, the brightness gradient, that is, the brightness difference before and after the brightness reduction, may be set by the user, which is not limited herein.
In one embodiment, the method further comprises:
and returning to the condition of determining that the terminal is in the navigation state under the condition that the second duration is less than the second preset duration.
Specifically, when the brightness of the target screen is the holding time of the second brightness, that is, the second time does not reach the second preset time, the terminal returns to the step after the start, so that the screen brightness can be adjusted based on the eye gazing direction of the user in the navigation process.
And S207, closing the target screen.
Specifically, the terminal adjusts the brightness of the target screen to the darkest, that is, closes the target screen, and jumps to S201 to continuously adjust the brightness of the target screen.
And S208, adjusting the brightness of the target screen to be normal brightness.
Specifically, the terminal adjusts the brightness of the target screen to the normal brightness, and ends the execution, i.e., S209.
Therefore, the process of dynamically adjusting the screen brightness of the terminal is completed, in the process, the eyeball tracking technology is utilized during navigation, the current watching direction of eyes of a user is identified, whether the user watches a target screen is determined, and then the brightness of the target screen is correspondingly adjusted, so that the power consumption of the terminal is reduced on one hand, the stimulation of the screen brightness to the eyes of the user during navigation is reduced on the other hand, the potential safety hazard is reduced, and the safety is improved.
After S207 is executed with respect to fig. 3, the car-in-vehicle screen is already closed, and then if it is detected that the user gazes at the target screen, the brightness of the target screen needs to be restored to the normal brightness. The time consumption required by the brightness recovery process is longer than that required by the brightness recovery process from dark brightness to normal brightness, the time required by eyes of a user to be concentrated on a target screen is correspondingly prolonged, and the target screen is suddenly brighter, so that the eyes of the user are greatly stimulated, and further driving potential safety hazards are caused, so that the embodiment of the application also provides a method for gradually brightening the target screen by closing or gradually brightening in a gradient manner, so that the eyes of the user can adapt to brightness change of the target screen, and the potential safety hazards are reduced; and contributes to reduction of power consumption.
This is illustrated below in connection with fig. 4.
In one embodiment, fig. 4 shows a flow of another dynamic adjustment method for the brightness of the terminal screen, which can be applied to a process in which the target screen is changed from dark to light. Referring to fig. 4, the method may further include:
s310, obtaining a third duration between the current moment and the next key action moment.
The key action corresponds to the navigation route, wherein the vehicle does not travel along a straight line any more, but turns, leans to the side, reaches a destination or goes through a special road section and the like. Illustratively, the key actions may be the next intersection to turn, the next branch to drive left or right, the arrival destination or the entering and exiting tunnel, etc., and these key actions may be set by the user according to the needs.
When the navigation software in the terminal prompts key actions, the user can check the navigation route displayed by the target screen with high probability so as to confirm the driving route. Based on the method, at a certain moment before the next key action moment, the target screen can be adjusted from the closed state to the darker state in advance, so that the screen brightness can be adjusted to the normal brightness quickly when the user views the navigation route.
In this step, the terminal may obtain, through the navigation software, how long the terminal has been away from the next key action, that is, a time length between the current time and the next key action time, that is, a third time length.
And S320, judging whether the third time length is equal to or less than a third preset time length.
And the third preset time length is used for determining how long the brightness of the target screen is adjusted in advance. And the third time length is gradually reduced along with the traveling of the vehicle, the current time is closer to the next key action time, and when the current time is close to a certain degree (namely the third preset time length), the brightness of the target screen can be adjusted.
In this step, the terminal may compare the third duration with a relative size of a third preset duration, that is, determine whether the third duration is equal to or less than the third preset duration; if yes, the current moment is closer to the next key action moment, and the subsequent brightness adjustment step can be executed, namely S330 is executed; if not (N), the current time is still far away from the next key action time, and at this time, the process returns to S310, namely the third time length is continuously obtained.
For example, the third preset time period may be 10s, 15s or other time periods, which may be set by the user based on the requirement, and is not limited herein.
S330, under the condition that the third duration is equal to or less than a third preset duration, adjusting the brightness of the target screen to fourth brightness; the fourth luminance is lower than the first luminance.
And when the third time length is less than or equal to the third preset time length, the next key action is about to occur, at this time, the target screen is adjusted from the closed state to the open state, and the brightness of the target screen is adjusted to fourth brightness, namely, the target screen is adjusted to darker brightness which is lower than the first brightness (or normal brightness).
Then, when the user watches the target screen, the brightness of the target screen is adjusted from the fourth brightness to the first brightness, so that the gradient adjustment of the brightness of the target screen is realized, the eyes of the user can adapt to the change of the brightness, the stimulation to the eyes of the user is reduced, the potential safety hazard is reduced, and the driving safety is improved; meanwhile, the power consumption is reduced.
The method flows shown in fig. 2, 3 and 4 may each be implemented, for example, by a software process in the terminal.
According to the terminal screen brightness adjusting method provided by the embodiment of the application, when the eyes of a user watch a target screen, the brightness of the target screen is kept at a high brightness, so that the user can conveniently check a navigation map (including a navigation route); when the eyes of a user watch the front and focus on driving without watching the target screen, the brightness of the target screen becomes dark, so that the power consumption of the terminal is reduced, the stimulation to the eyes of the user is avoided, the attention of the user to the road conditions in the front and other peripheral directions is improved, and the driving safety is improved. And when the low-brightness state is maintained for a period of time, the target screen is closed, and the power consumption is further reduced.
