Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to flexibly realize display control of a mobile terminal, embodiments of the present invention provide a display control method, apparatus, device, and medium for a mobile terminal.
Example 1:
fig. 1 is a schematic diagram of a display control process of a mobile terminal according to an embodiment of the present invention, where the process includes the following steps:
s101: and acquiring target parameter information between the eyes of the current watching user and the folding screen.
The display control method of the mobile terminal provided by the embodiment of the invention is applied to the mobile terminal, in particular to the mobile terminal with a folding screen (also called as a folding screen terminal).
It is to be understood that, unless otherwise stated, the foldable screen according to the embodiment of the present invention may be a foldable screen in a fully unfolded state (in this case, the foldable screen may be understood as one screen), or may be a foldable screen in a folded state (in this case, the foldable screen may be understood as a separate screen formed after being folded, for example, the foldable screen forms two separate screens after being folded).
The target parameter information between the two eyes of the current watching user and the folding screen is target distance information between the folding screen and the two eyes of the current watching user and target angle information between the two eyes of the current watching user and the folding screen.
The currently watched user may be one user or multiple users, if the currently watched user is one user, the target parameter information between the two eyes of the one user and the folding screen is obtained, and if the currently watched user is multiple users, the target parameter information between the two eyes of the target user among the multiple users and the folding screen is obtained, where the target user among the multiple users may be an arbitrarily selected user, may be a user closest to the folding screen among the multiple users, and may be a primary user of the multiple users (for example, the primary user may be a terminal holder).
In order to obtain the above target parameter information, in the embodiment of the present invention, the mobile terminal needs to have a folding screen, at least one ranging sensor, and at least one camera. The distance measuring sensor may be a distance measuring sensor such as an infrared sensor or an ultrasonic distance measuring sensor, or may be another sensor having a distance measuring function, and the type of the distance measuring sensor is not particularly limited in the embodiment of the present invention.
The mobile terminal device may start to acquire target parameter information between two eyes of a current viewing user and a folding screen in a setting scene, for example, the setting scene may be when the mobile terminal device is in an unlocked state, or the setting scene may be when a preset type of application installed on the terminal device is opened, where the preset type of application may be a video viewing application, a novel reading application, a news reading application, an instant messaging application, and the like.
When the mobile terminal starts to acquire target parameter information between the eyes of the current watching user and the folding screen, the ranging sensor sends a measuring signal which is perpendicular to the plane where the folding screen is located and the emitting direction of the measuring signal is a preset direction according to a set period so as to measure target distance information between the eyes of the current watching user and the ranging sensor, wherein the folding screen can be the folding screen where the ranging sensor is located. The camera can shoot image information while the distance measuring sensor sends a measuring signal, and the target angle information of the current watching user can be determined by combining the image information with the distance information measured by the distance measuring sensor.
S102: and determining target display parameters corresponding to the target parameter information according to the corresponding relation between the pre-stored parameter information and the display parameters of the folding screen.
Generally, a user often controls the mobile terminal when the distance between the eyes and the folding screen or the sight line of the user changes. In order to implement display control on the mobile terminal, in the embodiment of the present invention, the mobile terminal device may be adjusted by adjusting the display state corresponding to the display parameter, so that the mobile terminal may pre-store a corresponding relationship between the parameter information and the display parameter of the folding screen, for example, a relationship between different distance information and a screen display character size parameter and/or a relationship between different angle information and an included angle between two screens of the folding screen. The correspondence relationship between the parameter information and the display parameters of the folding screen, which is stored in advance, may be obtained through a large number of experiments, or may be set according to the use habits or preferences of the user.
Wherein the parameter information comprises a character size parameter and/or an included angle. For example, if the target parameter information is target distance information between the folding screen and the currently viewed user's eyes, a target display parameter corresponding to the target distance information may be determined according to a relationship between the pre-stored distance information and a screen display character size parameter, where the target display parameter is a target character size parameter. Or if the target parameter information is target angle information between the two eyes of the currently watched user and the folding screen, determining a target display parameter corresponding to the target angle information according to a relationship between angle information stored in advance and an included angle between two screens of the folding screen, wherein the target display parameter is a target included angle. After the mobile terminal receives the target parameter information, if the target parameter information is target distance information between the folded screen and the eyes of the currently watched user and the target parameter information is target angle information between the eyes of the currently watched user and the folded screen, target display parameters corresponding to the target distance information and the target angle information can be determined through a relationship between pre-stored distance information and screen display character size parameters and a relationship between pre-stored angle information and included angles of two screens of the folded screen, wherein the target display parameters are target character size parameters and target included angles.
Describing by a specific example, if the acquired target parameter information is target distance information between the folding screen and the eyes of the user currently watching the folding screen, and the target distance information is 50cm, determining a screen display character size parameter corresponding to the distance information with the value of 50cm according to a relationship between the pre-stored distance information and the screen display character size parameter, and taking the screen display character size parameter as the target character size parameter corresponding to the target parameter information. If the obtained target parameter information is target distance information between the folded screen and the eyes of the currently watched user and the target parameter information is target angle information between the eyes of the currently watched user and the folded screen, the target angle information is 30 degrees, and the target distance information is 70cm, according to the relationship between the pre-stored distance information and the size parameter of the screen display character and the relationship between the pre-stored angle information and the included angle between the two screens of the folded screen, the size parameter of the screen display character corresponding to the distance information with the value of 70cm and the included angle between the two screens of the folded screen corresponding to the angle information with the value of 30 degrees are determined, and the determined size parameter of the screen display character and the determined included angle between the two screens of the folded screen are used as the size parameter of the target character and the target included angle corresponding to the target parameter information.
S103: and if the current display state of the mobile terminal is inconsistent with the target display parameter, adjusting the display state of the mobile terminal according to the target display state.
In order to facilitate the implementation of display control on the mobile terminal, in the embodiment of the present invention, the display state of the current mobile terminal needs to be compared with the determined target display state, and whether the display state of the current mobile terminal is inconsistent with the target display state is determined, if not, it is indicated that the display state of the current mobile terminal is not suitable for the state of the current user, a display parameter of the current mobile terminal needs to be adjusted according to the target display state, if consistent, it is indicated that the display state of the current mobile terminal is suitable for the state corresponding to the current user, and it is not required that the mobile terminal adjusts the current display state, and the mobile terminal continues to maintain the current display state.
For example, the process of adjusting the display state of the current mobile terminal according to the target display state may be adjusting the display state of the current mobile terminal according to a control instruction corresponding to the target display state.
The display parameters comprise the size of the characters displayed on the screen and the included angle between the two screens of the folding screen.
The target display parameter may be a target character size parameter or a target angle, or may be a target character size parameter and a target angle. And when the target display parameter is a target character size parameter, judging whether the current screen display character size of the mobile terminal is inconsistent with the target character size parameter, and if not, correspondingly adjusting the display character size of the mobile terminal by using a corresponding control instruction according to the target character size parameter.
And when the target display parameter is a target included angle, judging whether the included angle between the two screens of the current folding screen of the mobile terminal is inconsistent with the target included angle, and if not, correspondingly adjusting the included angle between the two screens of the folding screen of the mobile terminal by using a corresponding control instruction according to the target character size parameter.
When the target display parameters are the target character size parameter and the target included angle, judging whether the current screen character size parameter of the mobile terminal and the included angle between the two screens of the folding screen are inconsistent with the target character size parameter and the target included angle, if any one of the target display parameters of the target character size parameter and the target included angle is inconsistent with the current display parameter corresponding to the mobile terminal, considering that the current display parameter of the mobile terminal is inconsistent with the target display parameter, and converting the current display parameter into a corresponding control instruction according to the target display state to correspondingly adjust the display state of the mobile terminal.
Specifically, the control instruction may include at least one of an instruction for controlling the mobile terminal to adjust the size of the displayed characters on the screen, an instruction for controlling the motor at the bent portion of the foldable screen to rotate the screen of the foldable screen to a corresponding angle, an instruction for controlling the mobile terminal to adjust the size of the displayed fonts on the screen, and an instruction for controlling the motor at the bent portion of the foldable screen to rotate the screen of the foldable screen to a corresponding angle.
According to the embodiment of the invention, the target parameter information between the eyes of the currently watched user and the folding screen is acquired, the target display parameter corresponding to the target parameter information is determined according to the corresponding relation between the prestored parameter information and the display parameter of the folding screen, and when the current display parameter of the mobile terminal is inconsistent with the target display parameter, the display state of the mobile terminal is adjusted according to the target display parameter, and the display state corresponding to the target display parameter can be regarded as the appropriate watching state when the current user uses the mobile terminal, so that the display control of the mobile device can be intelligently and flexibly carried out, and the user does not need to manually adjust a mobile phone support, so that the operation process of the user is simplified, the time is saved, and the user experience is improved.
Example 2:
in order to determine target parameter information, so as to intelligently and flexibly perform display control on a mobile device, on the basis of the above embodiment, in an embodiment of the present invention, the target parameter information between the two eyes of the current viewing user and the folding screen includes:
at least one of target distance information between the folded screen and the eyes of the currently viewed user, and target angle information between the eyes of the currently viewed user and the folded screen.
That is, the target parameter information includes target distance information and/or target angle information.
Generally, a user often controls the mobile terminal when the distance between the eyes and the folding screen or the sight line of the user changes. And to realize display control of the mobile terminal.
Usually, a user often controls the mobile terminal when the distance between the two eyes and the folding screen or the sight line of the user changes, and the change of the distance between the two eyes and the folding screen or the sight line of the user brings about the change of parameter information such as distance information angle information, so that the display state of the mobile terminal can be adjusted by acquiring the parameter information and according to the display parameters of the mobile terminal corresponding to the parameter information. Specifically, the distance information may refer to target distance information between the folding screen and the eyes of the user currently watching the folding screen, and the angle information may refer to target angle information between a position variation amount of the eyes and a preset straight line.
In order to facilitate obtaining of target parameter information between the two eyes of the current watching user and the folding screen, in the embodiment of the present invention, a fixed position may be respectively set at the two eyes as reference positions of the two eyes, and the target angle information may be determined according to an angle between the fixed position at the two eyes and a preset straight line. For example, the fixed positions set at both eyes of the currently viewing user may be a midpoint of a line connecting both eyes, any inner-eye angular position of both eyes, any pupil position of both eyes, or the like.
The acquiring of the target distance information between the folding screen and the currently viewed user eyes comprises:
acquiring first distance information based on a distance sensor, and acquiring current first image information;
and judging whether human eyes exist in the first image information, if so, taking the collected first distance information as the target distance information between the folding screen and the two eyes of the user who watches at present.
When the distance measuring sensor sends a measuring signal which is perpendicular to the plane where the folding screen is located and the emitting direction of the measuring signal is the preset direction according to the set period, the distance between an object meeting in the sending direction and the distance measuring sensor is measured, namely the distance between the object meeting in the sending direction and the folding screen is measured, and the distance is the first distance information.
The target distance information required by the mobile terminal is distance information between the folding screen and the eyes of the user who watches at present, and the ranging sensor cannot know whether the distance information measured in the current sending direction is the distance information between the folding screen and the eyes of the user who watches at present, so that a camera which can be installed on the same folding screen with the ranging sensor can shoot image information in the sending direction of the measuring signal while the ranging sensor sends the measuring signal, and the image information is called as first image information for convenience of description. If the current watching user watches the mobile terminal, the camera can shoot the human eye of the user in the shooting range of the camera, so that the shot human eye of the user can be used as the human eye of the current watching user. Therefore, the mobile terminal can process the first image information shot by the camera, detect whether the first image information contains human eyes, if the first image information contains human eyes, the current watching user watches the mobile terminal, and the distance measuring sensor measures the first distance information between an object encountered in the sending direction and the distance measuring sensor as the target distance information of the folding screen and the two eyes of the current watching user; if the first image information does not contain human eyes, the fact that the current watching user is probably not watching the mobile terminal is shown, since the current watching user is not watching the mobile terminal, the display state of the mobile terminal can not be adjusted, namely the target distance information between the folding screen and the current watching user is not acquired, and the acquired first distance information and the first image information can be deleted.
In addition, in the embodiment of the present application, acquiring at least one of the target angle information between the amount of change in the positions of the two eyes and a preset direction includes:
acquiring second distance information based on the distance sensor, and acquiring current second image information;
identifying first coordinate information of human eyes in the second image information, and converting the first coordinate information into physical coordinate information relative to the folding screen;
and determining the target angle information according to the physical coordinate information.
The second distance information is the distance between the two eyes of the current watching user and the distance measuring sensor measured by the current distance measuring sensor, namely the distance between the two eyes of the current watching user in the sending direction and the folding screen. The camera installed on the same folding screen with the ranging sensor can shoot the image information of the eyes of the current watching user while acquiring the second distance information, and the image information of the eyes of the current watching user is the second image information.
Specifically, according to the processing of the mobile terminal on the second image information, a fixed position is set for the position of the human eyes in the second image information, and the set position may represent the positions of the two eyes in the second image information. And determining two-dimensional position information corresponding to the set position in the image according to the set image coordinate axis, wherein the two-dimensional position information of the set position in the second image information is first coordinate information.
Further, according to the parameters of the camera, the first coordinate information of the set position of the human eye is converted into physical coordinate information relative to the folding screen, and the physical coordinate information can be three-dimensional coordinate information in a world coordinate system.
It should be noted that, a process of specifically converting the first coordinate information of the set position into the physical coordinate information corresponding to the folding screen is the same as that of the conversion process in the prior art, and is not described herein again.
The coordinate in the vertical direction in the physical coordinate information of the set position may be a distance in the vertical direction of the human eyes in the second image information relative to the position of the ranging sensor, and the target angle information between the two eyes of the currently viewed user and the folding screen may be determined by a mathematical algorithm such as a trigonometric function according to the distance in the numerical direction and the acquired second distance information.
The target angle information can be set to be in a positive direction and a negative direction, the physical coordinate information of the ranging sensor in the folding screen can be set to be an original point, and if the coordinate in the vertical direction in the physical coordinate information of the set position is larger than the coordinate in the vertical direction in the physical coordinate information of the ranging sensor in the folding screen, the target angle information can be determined to be positive; if the coordinate in the vertical direction in the physical coordinate information of the set position is smaller than the coordinate in the vertical direction in the physical coordinate information of the folding screen relative to the ranging sensor on the folding screen, it can be determined that the target angle information is negative.
According to the embodiment of the invention, the acquired target distance information and/or target angle information are used, so that a basis is provided for determining the corresponding display state of the mobile terminal according to the state of the current watching user.
Example 3:
in order to determine a target display state corresponding to target parameter information, so as to intelligently and flexibly perform display control on a mobile device, on the basis of the above embodiment, in an embodiment of the present invention, when the target parameter information is target distance information between the folding screen and both eyes of the currently viewed user, determining a target display parameter corresponding to the target parameter information according to a correspondence between pre-stored parameter information and a display parameter of the folding screen includes:
and determining a target character size parameter corresponding to the target distance information according to the target distance information and the relationship between the pre-stored distance information and the screen display character size parameter.
Generally, when the mobile terminal displays, the size of the displayed characters is fixed, so that it is possible that when the user is too far away from the mobile terminal (for example, the distance from the mobile terminal is longer than a preset distance), the user cannot clearly see the content currently displayed by the mobile terminal, and when the user is too close to the mobile terminal (for example, the distance from the user to the mobile terminal is shorter than the preset distance), the user may damage the eyesight of the user. In order to avoid the above problem, in the embodiment of the application, the size of the characters displayed on the screen of the mobile terminal can be adaptively adjusted according to the distance information between the two eyes of the user and the folding screen, and the user can clearly view the content displayed on the mobile terminal without manually adjusting the position of the mobile terminal.
The mobile terminal can determine the target character size parameter corresponding to the target distance information according to the determined target distance information and the corresponding relation between the pre-stored distance information and the screen display character size parameter. For example, the size adjustment ratio of the display content is determined through the distance information between the eyes and the folding screen, and then the ratio is multiplied by the preset reference size of the display content, so as to determine the size of the screen display characters, wherein the determined size of the screen display characters is the size of the target characters corresponding to the target distance information.
Describing an embodiment, the obtained target parameter information is target distance information between the folding screen and the two eyes, the target distance information is 40cm, the pre-stored distance information with a value of 40cm is determined according to the value of the target distance information, the ratio of the distance information with the value of 40cm to the size adjustment of the display content is 80%, that is, when the distance between the two eyes and the folding screen is 40cm, the distance between the two eyes of the user and the mobile terminal is short, the size of the display content on the screen needs to be adjusted, the size of the display content after adjustment is 80% of the reference size of the preset display content, and the size of the display character on the screen obtained by multiplying the ratio and the reference size of the preset display content is the size of the target character corresponding to the target distance information.
In addition, in this embodiment of the application, when the target parameter information is target angle information between a connection line between the foldable screen and the two eyes and a preset straight line, the determining, according to a correspondence between pre-stored parameter information and display parameters of the foldable screen, a target display parameter corresponding to the target parameter information includes:
and determining a target included angle corresponding to the target angle information according to the target angle information and the relationship between the angle information stored in advance and the included angle between the two screens of the folding screen.
Generally, if a posture of a user when watching a mobile terminal changes or the user moves a position when watching the mobile terminal, a line of sight of the user when watching the mobile terminal may change, for example, a watching angle changes, and if the mobile terminal continues to display at an angle before the user changes, the user may not completely watch the content displayed by the mobile terminal due to screen reflection or a change in a user field of view. In order to avoid the above problem, in the embodiment of the present application, an included angle between two screens of the folding screen may be adaptively adjusted according to the target angle information between the two eyes of the currently watching user and the folding screen, and the user may clearly view the content displayed on the mobile terminal without manually adjusting the position of the mobile terminal.
The mobile terminal can determine a target included angle corresponding to the target angle information according to the determined target angle information and the relationship between the angle information stored in advance and the included angles of the two screens of the folding screen. For example, the process of adjusting the display state of the mobile terminal through the target included angle may be to provide kinetic energy through a motor disposed in the mobile terminal to drive a rotor in the rotating shaft of the folding screen to rotate, and use the target included angle as an angle for controlling the rotation of the rotor, or use an angle difference between the target included angle and a preset included angle as an angle for controlling the rotation of the rotor.
The preset straight line can be any reference line such as a horizontal line and a line perpendicular to the horizontal plane, which can measure relative change of the sight of the user, when the included angle between the two screens of the folding screen is determined, the preset optimal angle range of the two eyes when the user watches the screen, the acquired angle information between the connection line of the two eyes and the preset straight line, and the included angle between the two screens of the folding screen is determined according to the relationship between the angle information and the optimal angle range.
Specifically, when the acquired target parameter information is target angle information between a connection line between the folding screen and the two eyes and a preset straight line, pre-stored angle information is determined according to a numerical value of the target distance information, according to a preset optimal angle range of the two eyes when watching the screen, the acquired angle information between the connection line between the two eyes and the preset straight line is determined according to a relation between the angle information and the optimal angle range, so that an included angle between two screens of the folding screen is determined, and the included angle between the two screens of the folding screen is a target included angle corresponding to the target angle information.
For example, the preset line is a horizontal line, and the preset optimal angle is set when the included angle between the horizontal line and the line connecting the two eyes and the folding screen is 30 degrees. The obtained target parameter information is target angle information between a connecting line of the folding screen and the two eyes and a horizontal line, the target angle information is 45 degrees, an included angle between two screens of the corresponding folding screen is obtained by determining the current target angle information and the optimal angle value, and the determined included angle between the two screens of the folding screen is the target included angle corresponding to the target angle information.
Due to the fact that the corresponding relation of the included angles between the two screens of the folding screen and the different angle information is pre-stored, when the obtained target parameter information is the target angle information, the corresponding target included angle can be determined in the corresponding relation of the included angles between the two screens of the folding screen and the different angle information pre-stored according to the target angle information, a basis is provided for a follow-up mobile terminal to adjust the included angle between the two screens of the folding screen according to the angle between the connection line of the eyes and the folding screen and the preset straight line, the mobile terminal can flexibly adjust the included angle between the two screens of the folding screen according to the sight of a user, and user experience is improved.
When the target parameter information is target distance information between the folding screen and the two eyes and target angle information between a connecting line between the folding screen and the two eyes and a preset straight line, determining a target display parameter corresponding to the target parameter information according to a corresponding relationship between prestored parameter information and a display parameter of the folding screen includes:
and determining the target font size parameter and the target included angle corresponding to the target distance information and the target angle information according to the target distance information, the target angle information and the relationship among the prestored distance information, the prestored angle information, the screen display font size parameter and the included angle between the two screens of the folding screen.
Because the distance between the two eyes and the folding screen and the angle between the connecting line of the two eyes and the folding screen and the preset straight line are changed when the user uses the mobile terminal, the mobile terminal not only needs to adjust the included angle between the two screens of the folding screen, but also needs to adjust the size of the displayed font of the screen. For the above situation, the target parameter information acquired by the mobile terminal may be target distance information and target angle information.
The determination of the target distance information and the target font size and the target included angle corresponding to the target angle information according to the target angle information and the target distance information in the target distance information is the same as that in the above technical solution, and is not repeated here.

s201: acquiring target parameter information between the eyes of a current watching user and the folding screen, wherein the target parameter information is target distance information and target angle information.
