Detailed Description
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart illustrating steps of a screen refreshing method according to the present application is shown, where the method is applied to a car-mounted device and the like, and the method may specifically include the following steps:
in step S101, in the process of refreshing the screen of the in-vehicle device at the default screen refresh frequency, current state information of the screen is acquired.
In this application, the current state information of the screen of the in-vehicle device includes: information currently displayed on the screen and whether the screen is currently being manipulated, etc.
The currently displayed information includes: navigation information, voice recognition information, meter information, and the like.
Alternatively, the currently displayed information includes: the application programs may include an application program for navigation, an application program for interconnection between the mobile phone and the car equipment, and the application program for interconnection between the mobile phone and the car equipment includes Carplay, carplife, and the like.
Alternatively, the currently displayed information includes: text, images, video, and the like.
In the application, under the condition that the operating system of the car machine device is an android operating system, the current State information of the screen of the car machine device can be acquired based on a State Collector component of an android framework layer in the android operating system.
In step S102, a first screen refresh frequency applicable to the current state information is acquired. The first screen refresh rate is lower than a default screen refresh rate of the screen.
Typically, the in-vehicle device may refresh the screen at a default screen refresh frequency. However, the default screen refresh rate is usually higher, so refreshing the screen at the default screen refresh rate consumes more system resources of the in-vehicle device.
In the present application, the screen refresh frequency for which different state information is applicable may be different.
For example, in a case where the more important the information displayed on the screen is, or in a case where the service requirement of the user can be realized only by viewing the information displayed on the screen by the user, the longer the time period for the user to view the information displayed on the screen is, or the more careful the user views the information displayed on the screen is, the more convenient the user can view the information displayed on the screen, the higher the screen refresh frequency can be used to refresh the screen.
In the case that the information displayed on the screen is less important, or in the case that the user can realize the business requirement of the user without watching the information displayed on the screen, the time length for the user to watch the information displayed on the screen is shorter or the careful degree for the user to watch the information displayed on the screen is lower, so that the screen can be refreshed at a lower screen refreshing frequency (meanwhile, the screen refreshing frequency needs to meet the minimum requirement of the user on the screen display effect) in order to save system resources and reduce the subjective feeling of the user watching the information displayed on the screen to a small extent.
In general, if the screen is refreshed at a frequency higher than or equal to a specific screen refresh frequency with a specific screen refresh frequency as a boundary, the user will not easily perceive the "flash" phenomenon on the screen, and if the screen is refreshed at a frequency lower than the specific screen refresh frequency, the user will easily perceive the "flash" phenomenon on the screen, and the default refresh frequency is usually higher than the specific screen refresh frequency.
For example, the specific screen refresh rate includes 24Hz, etc., and the default refresh rate is 60Hz, which is 24Hz higher than the specific screen refresh rate.
Therefore, in order to save system resources of the in-vehicle device, in an embodiment of the present application, a first screen refresh frequency applicable to the current state information may be selected within a frequency interval greater than or equal to a specific screen refresh frequency and less than a default refresh frequency, and then step S103 is performed.
Alternatively, in an embodiment of the present application, although the information is displayed on the screen, the user may not view the information displayed on the screen, and therefore, in a case where the user does not view the information displayed on the screen, no matter what refresh frequency refreshes the screen, it has no influence on the subjective feeling of the user, and therefore, it is also possible to select one screen refresh frequency less than a specific screen refresh frequency and use the selected screen refresh frequency as the first screen refresh frequency, and then execute step S103.
For a specific process of acquiring the first screen refresh frequency suitable for the current status information, reference may be made to the following embodiments, which are not described in detail herein.
In the application, under the condition that the operating system of the car machine device is an android operating system, the first screen refresh frequency applicable to the current State information can be acquired based on a State Collector component of an android framework layer in the android operating system.
In step S103, the screen refresh frequency of the screen is switched from the default screen refresh frequency to the first screen refresh frequency, so that the in-vehicle device refreshes the screen at the first screen refresh frequency.
In an embodiment of the application, a State Collector component of an android framework layer in an android operating system can transmit a first screen refresh frequency to a Surface flanger component of a local framework layer in the android operating system, and the Surface flanger component of the local framework layer in the android operating system can modify the screen refresh frequency into the first screen refresh frequency based on a DispSync class, so that the screen refresh frequency of a screen can be switched from a default screen refresh frequency to the first screen refresh frequency, and then a car machine device can refresh the screen at the first screen refresh frequency.
In an embodiment of the application, a State Collector component of an android framework layer in an android operating system can transmit a first screen refresh frequency to a Surface flag component of a local framework layer in the android operating system, and the Surface flag component of the local framework layer in the android operating system can modify the screen refresh frequency to the first screen refresh frequency based on a non-public frame skipping interface Binder, so that the screen refresh frequency of a screen is switched to the first screen refresh frequency from a default screen refresh frequency, and then a car machine device can refresh the screen at the first screen refresh frequency.
In the method, the current state information of the screen is acquired in the process of refreshing the screen of the vehicle-mounted device at the default screen refreshing frequency, and the first screen refreshing frequency suitable for the current state information is acquired. And the first screen refreshing frequency is lower than the default screen refreshing frequency of the screen, and the screen refreshing frequency of the screen is switched from the default screen refreshing frequency to the first screen refreshing frequency, so that the in-vehicle equipment refreshes the screen at the first screen refreshing frequency. Through the method and the device, the screen can be refreshed at the first screen refreshing frequency lower than the default screen refreshing frequency, so that system resources of the vehicle equipment can be saved.
In addition, the first screen refresh frequency may be a screen refresh frequency that satisfies a display effect of the screen under the condition of the current state information, so that the viewing experience of the user may be considered under the condition of saving the system resources of the in-vehicle device, for example, the user may be prevented from feeling "one flash" due to the excessively low refresh frequency, and the viewing experience of the user may be prevented from being reduced under the condition of saving the system resources of the in-vehicle device.
In addition, system resources of the vehicle equipment are saved, so that the vehicle equipment can have more system resources for doing other things, the performance of the vehicle equipment can be improved, the running smoothness of the vehicle equipment is improved, and poor experience brought to a user due to the fact that the performance and the running smoothness of the vehicle equipment are poor is avoided.
In an embodiment of the application, when the screen refresh frequency of the screen is switched from the default screen refresh frequency to the first screen refresh frequency, the screen refresh frequency can be directly switched from the default screen refresh frequency to the first screen refresh frequency at one time, so that the screen of the in-vehicle device is refreshed at the default screen refresh frequency at the first moment, and the screen is refreshed at the first screen refresh frequency at the next moment.
However, if the difference between the default screen refresh frequency and the first screen refresh frequency is large, the user may have a distinct switching experience after directly switching the screen refresh frequency of the screen from the default screen refresh frequency to the first screen refresh frequency, which results in a large difference between the user experience of the screen refresh before and after switching the screen refresh frequency, and may reduce the user experience.
Therefore, in order to avoid reducing the user experience, in another embodiment of the present application, when the screen refresh frequency of the screen is switched from the default screen refresh frequency to the first screen refresh frequency, the screen refresh frequency may be smoothly and stepwise switched from the default screen refresh frequency to the first screen refresh frequency.
For example, an intermediate screen refresh frequency may be selected among screen refresh frequencies that are between the default screen refresh frequency and the first screen refresh frequency, and then the screen refresh frequency of the screen is smoothly switched from the default screen refresh frequency to the first screen refresh frequency in a stepwise manner based on the intermediate screen refresh frequency. For example, the screen refresh frequency of the screen is switched from the default screen refresh frequency to the intermediate screen refresh frequency; and after the interval preset time length, switching the screen refreshing frequency of the screen from the middle screen refreshing frequency to the first screen refreshing frequency. The preset time period may be determined according to actual situations, and may include, for example, 0.5 second, 1 second, or 1.5 seconds, which is not limited in this application.
In one example, in the case that the intermediate screen refresh frequency is multiple, the screen refresh frequency of the screen may be first switched from the default screen refresh frequency to the intermediate screen refresh frequency 1, and then the screen refresh frequency of the screen may be switched from the intermediate screen refresh frequency 1 to the intermediate screen refresh frequency 2 every a preset time length. The intermediate screen refreshing frequency x is smaller than the intermediate screen refreshing frequency x +1, so that the screen refreshing frequency of the screen is smoothly and stepwisely switched to the first screen refreshing frequency from the default screen refreshing frequency. x is greater than or equal to 1 and less than n.
In another embodiment of the present application, referring to fig. 2, step S102 includes:
in step S201, a screen refresh frequency corresponding to the current state information is searched for in the correspondence between the state information and the screen refresh frequency.
In the application, all the state information possibly existing in the screen of the vehicle equipment can be counted in advance, then for any one of the counted state information, a technician can analyze the screen refreshing frequency suitable for the state information according to the actual situation, the screen refreshing frequency suitable for the state information is lower than the default screen refreshing frequency and meets the display effect of the screen (the display effect meeting the screen comprises the feeling that a user cannot feel 'one flash and one flash'). And then forming a corresponding table entry by the state information and the analyzed screen refreshing frequency, and storing the corresponding table entry in the corresponding relation between the state information and the screen refreshing frequency, wherein the same is true for each piece of other counted state information.
Therefore, the screen refresh frequency corresponding to the current state information can be searched in the correspondence between the state information and the screen refresh frequency, and then step S202 is performed.
And the screen refreshing frequency in each corresponding table entry in the corresponding relation between the state information and the screen refreshing frequency is lower than the default screen refreshing frequency.
In step S202, a first screen refresh frequency is determined according to the searched screen refresh frequency.
In an embodiment of the present application, when the found screen refresh frequency is one, the found screen refresh frequency may be used as the first screen refresh frequency.
In another embodiment of the present application, in a case that the found screen refresh frequency is at least two and the at least two screen refresh frequencies are different, one screen refresh frequency may be selected from the found at least two different screen refresh frequencies and used as the first screen refresh frequency, and a specific selection manner may refer to an embodiment shown later and will not be described in detail herein.
Further, after the screen is refreshed at the first screen refresh frequency, system resources can be saved, but as the refresh interval of the screen is increased, a user may feel a "flash" when viewing information displayed on the screen, which may reduce the viewing experience of the user.
Therefore, in order to avoid the user from feeling the feeling of 'one flash and one flash', the application can support that after the screen is refreshed at the first screen refreshing frequency, the user can manually control the car-in-vehicle device to increase the screen refreshing frequency.
For example, a user may enter an increase operation for increasing the screen refresh frequency on the in-vehicle device. The in-vehicle device may receive an increase operation for increasing a screen refresh frequency, which is input by a user. Then, the screen refreshing frequency of the screen can be switched from the first screen refreshing frequency to the second screen refreshing frequency according to the increasing operation, so that the in-vehicle device refreshes the screen at the second screen refreshing frequency, and the second screen refreshing frequency is higher than the first screen refreshing frequency, so that the screen refreshing frequency can be increased, the user can be prevented from feeling 'one flash and one flash' as much as possible, and the watching experience of the user can be improved.
In one mode, a sum of a specific refresh frequency increment and the first screen refresh frequency may be calculated to obtain a second screen refresh frequency, and then the screen refresh frequency of the screen is switched from the first screen refresh frequency to the second screen refresh frequency, so that the in-vehicle device refreshes the screen at the second screen refresh frequency.
After the in-vehicle device refreshes the screen at the second screen refreshing frequency, if the user still feels the 'one flash', the user can continue to manually control the in-vehicle device to increase the screen refreshing frequency until the user does not feel the 'one flash'.
After the in-vehicle device refreshes the screen at the second screen refreshing frequency, if the user does not feel the 'one-flash-one-flash' feeling any more, the user often does not continue to manually control the in-vehicle device to increase the screen refreshing frequency.
In this case, the second screen refresh frequency may be a screen refresh frequency that can be accepted by the user when the state information of the screen is the current state information, and therefore, in order to avoid that the user may feel a sense of "one flash and one flash" after the first screen refresh frequency is switched from the default refresh frequency to the refresh frequency of the screen again, in the correspondence between the state information and the screen refresh frequency, the in-vehicle device may replace the screen refresh frequency corresponding to the current state information with the second screen refresh frequency in a case where the second screen refresh frequency is less than the default refresh frequency and the increase operation is not received again within the preset time period after the screen is refreshed with the second screen refresh frequency.
Specifically, in one example, the searched screen refresh frequencies are at least two, the searched screen refresh frequencies are different, and the searched screen refresh frequencies are both smaller than the default refresh frequency.
Thus, referring to fig. 3, when one screen refresh frequency is selected from the at least two different searched screen refresh frequencies and is used as the first screen refresh frequency, the method may be implemented by the following processes, including:
in step S301, the line of sight direction of the user is acquired.
In this application, the fixed position in the car is provided with the camera, and the position of the screen of car machine equipment is also fixed unchangeable, consequently, can set up the position coordinate of camera and the position coordinate of the screen of car machine equipment in advance. In addition, the position coordinates of the eyes of the user in a normal situation when the user is located in the vehicle, for example, the position coordinates of the eyes of the user in a situation where the user is located in the main driving position, etc. may be counted, and the counted position coordinates of the eyes of the user may be set in the vehicle-mounted device.
The vehicle-mounted device can shoot an eye image of the user, determine the distance between the position of the pupil of the eye of the user and the center position of the eye in the eye image, and then determine the offset angle of the position of the pupil of the eye of the user relative to the center position of the eye according to the distance.
The eye is a sphere, the sphere has a center, the center of the eye and the center of the eye in the eye image shot by the camera are located on a straight line, the center of the eye and the pupil in the eye image shot by the camera are located on another straight line, and an included angle between the two straight lines is an offset angle of the pupil position relative to the center of the eye.
The in-vehicle device may determine a vector 1 having the position coordinates of the user's eyes as a start point and the position coordinates of the camera as an end point, and determine a vector 2 having the position coordinates of the user's eyes as a start point and the position coordinates of the screen as an end point. And the direction of the vector 3 obtained after the vector 1 is shifted by the offset angle is taken as the line-of-sight direction of the user.
In step S302, it is determined whether the line of sight direction of the user is directed to the screen.
Whether the included angle between the vector 3 and the vector 2 is smaller than a preset included angle is determined, the preset included angle includes 1 degree, 2 degrees or 3 degrees and the like, and the preset included angle can be specifically set according to the actual situation, and detailed description is not given here. In the case that the included angle between the vector 3 and the vector 2 is smaller than the preset included angle, it may be determined that the sight line direction of the user is directed to the screen. In the case where the angle between the vector 3 and the vector 2 is greater than or equal to a preset angle, it may be determined that the gaze direction of the user is not aligned with the screen.
In the case where the user' S gaze direction is not aligned with the screen, a lower screen refresh frequency of the at least two screen refresh frequencies found is determined as the first screen refresh frequency in step S303.
In the application, when the direction of the line of sight of the user is not aligned with the screen, it indicates that the user does not view information displayed on the screen, and at this time, refreshing the screen at a higher screen refresh frequency of at least two different screen refresh frequencies or refreshing the screen at a lower screen refresh frequency of at least two different screen refresh frequencies has no influence on subjective feeling of the user.
In the case where the user' S gaze direction is directed to the screen, a higher screen refresh frequency of the at least two screen refresh frequencies found is determined as the first screen refresh frequency in step S304.
In order to save system resources and avoid the user from feeling 'one flash and one flash', the higher screen refresh frequency of the at least two searched screen refresh frequencies can be determined as the first screen refresh frequency.
In one example, the searched screen refresh frequencies are at least two, the searched screen refresh frequencies are different, and the searched screen refresh frequencies are both smaller than the default refresh frequency.
Thus, referring to fig. 4, when one screen refresh frequency is selected from the at least two different searched screen refresh frequencies and is used as the first screen refresh frequency, the method may be implemented by the following processes, including:
in step S401, a current system resource utilization rate of the in-vehicle device is obtained.
The system resource utilization includes a Central Processing Unit (CPU) utilization and/or a memory utilization.
In step S402, it is determined whether the current system resource utilization rate of the in-vehicle device is less than a preset threshold.
The preset threshold may be determined according to practical situations, and may include, for example, 20%, 25%, 30%, etc., which is not limited in this application.
In the case that the current system resource utilization rate is smaller than the preset threshold, in step S403, a higher screen refresh frequency of the at least two searched screen refresh frequencies is determined as a first screen refresh frequency.
In the application, under the condition that the current system resource utilization rate is smaller than the preset threshold, it is indicated that the number of idle system resources of the in-vehicle device is large at this time, and the system resources of the in-vehicle device are generally not completely occupied after the screen is refreshed at the higher one of the at least two different screen refresh frequencies, so that the higher one of the at least two searched screen refresh frequencies can be determined as the first screen refresh frequency in order to avoid the user from feeling "one flash and one flash".
In the case that the current system resource utilization rate is greater than or equal to the preset threshold, in step S404, a lower screen refresh frequency of the at least two searched screen refresh frequencies is determined as a first screen refresh frequency.
In the application, when the current system resource utilization rate is greater than or equal to the preset threshold, it is indicated that the idle system resources of the in-vehicle equipment are less at this time, and in order to reserve part of the system resources for the in-vehicle equipment so that the in-vehicle equipment can also do other things, the lower screen refresh frequency of the at least two searched screen refresh frequencies can be determined as the first screen refresh frequency.
