Description

Screen display method and device for mobile terminal and mobile terminal

technical field

The present application relates to the field of terminal technology, in particular to the field of terminal display technology, and in particular to a screen display method and device for a mobile terminal.

Background technique

With the continuous development of mobile communication and touch control technologies, mobile terminals equipped with touch screens have become one of the most common smart devices in people's daily life. Since the size of the touch screen is limited by the size of the mobile terminal itself, the display area of the touch screen is generally not too large. This also leads to relatively small image content displayed on the terminal, so that the user may not be able to see the content displayed on the terminal clearly, especially for those elderly users with degraded eyesight, this problem is particularly prominent.

In order to solve the above-mentioned problems, mobile terminals in the prior art usually provide users with a screen zoom-in function. After this function is turned on, the mobile terminal can directly enlarge the picture displayed on the screen, so that the user can see the displayed content more easily. However, when the displayed picture is enlarged through the screen magnification function, the screen can only display part of the current picture. At this time, if the user wants to see the part of the picture beyond the screen, he needs to use multiple fingers to drag the picture on the screen at the same time to change its display position. This operation mode is comparatively complicated, and has reduced operation efficiency.

Detailed ways

The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

Please refer to FIG. 1 , which shows a process 100 of an embodiment of a screen display method for a mobile terminal. This embodiment is mainly exemplified by applying the method to a mobile terminal with a display screen, and the terminal may include but not limited to a smart phone, a tablet computer, an e-book reader, a laptop computer, a wearable device, and the like. The screen display method for a mobile terminal includes the following steps:

As shown in FIG. 1 , in step 101, it is detected whether the currently displayed image exceeds the screen display range of the terminal.

In this embodiment, the mobile terminal can first obtain the size of the currently displayed screen, and then compare the size of the screen with the screen size configured by the terminal to detect whether the screen currently displayed by the terminal exceeds the screen display range of the terminal. If the screen magnification function is enabled on the terminal, the terminal will automatically enlarge the picture displayed on the screen, resulting in the size of the current picture being larger than the screen size. At this point, the terminal can detect that the current display image exceeds the screen display range of the terminal.

It should be noted that, in addition to the screen magnification function that can magnify any picture displayed on the terminal, some specific pictures themselves can also be magnified, for example, picture files or web pages. In this case, the screen currently displayed by the terminal will also exceed the screen display range of the terminal, so the screen display method for a mobile terminal of the present application can also be applied.

Then, in step 102, if the screen display range of the terminal is exceeded, the offset information of the terminal is monitored.

In this embodiment, after it is detected in the above step 101 that the screen currently displayed by the terminal exceeds the screen display range of the terminal, the position change of the terminal can be continuously obtained to monitor the offset information of the terminal. Optionally, the offset information includes translation information and/or spin information. Wherein, the translation information may be used to describe the position movement of the terminal device in the three-dimensional space, and the spin information may be used to describe the rotation situation of the terminal device itself. When monitoring the offset information of the terminal, only the translation information of the terminal may be monitored, or only the spin information of the terminal may be monitored, or the translation information and spin information of the terminal may be monitored simultaneously. The specific offset information to be monitored can be set by the user according to actual needs.

Finally, in step 103, the display position of the screen is adjusted based on the offset information.

In this embodiment, after the offset information of the terminal is monitored in step 102 above, the display position of the current screen can be changed according to the offset information. Specifically, the offset information may include a moving distance and a moving direction. When adjusting the display position of the screen based on the offset information, the current screen can be moved along the moving direction by the distance specified by the moving distance, so as to adjust the screen to the position that the user wants to watch.

In an optional implementation of this embodiment, adjusting the display position of the picture based on the offset information further includes: determining a movement threshold of the picture according to the edge position of the picture; if the movement distance determined according to the offset information is greater than the movement threshold, then The moving threshold is taken as the moving distance determined according to the offset information. In this embodiment, when adjusting the display position of the screen based on the offset information, the edge position of the screen can be further determined according to the size of the screen itself and its current display position, and the movement required for displaying the edge position The distance is used as the movement threshold of the picture. When the screen movement distance determined according to the offset information is greater than the above-mentioned movement threshold, it means that the screen movement required by the offset information has exceeded the boundary range of the screen. At this time, the movement threshold can be used as the movement distance determined according to the offset information, so that the image stops when it moves to its edge, so as to avoid unnecessary picture movement.

The screen display method for a mobile terminal provided by the above-mentioned embodiments of the present application can first detect whether the screen currently displayed by the terminal exceeds the display range of its screen, and if so, monitor the offset information of the terminal, and based on the offset Information adjusts the display position of the screen on the terminal screen. The present application can adjust the display position of the screen on the terminal based on the position deviation of the terminal itself, which simplifies the operation process when the user moves the screen, thereby improving the operation efficiency when changing the screen display position.

Further referring to FIG. 2 , it shows a flow 200 of another embodiment of a screen display method for a mobile terminal.

As shown in FIG. 2, in step 201, it is detected whether the currently displayed image exceeds the screen display range of the terminal. In this embodiment, this step is the same as the above-mentioned step 101 and will not be repeated here.

Then, in step 202, if the screen display range of the terminal is exceeded, the translation information of the terminal is monitored.

In this embodiment, when it is detected in the above step 201 that the currently displayed image exceeds the screen display range of the terminal, the translation information of the terminal is monitored. In this embodiment, the translation information may include horizontal and vertical translation information, where the horizontal and vertical directions may refer to two directions perpendicular to each other within the plane where the terminal screen is located. Generally, the orientations of two adjacent sides of the rectangular screen can be set as landscape and portrait respectively. Specifically, when monitoring the translation information of the terminal, the translation information of the terminal in the horizontal direction and the vertical direction can be obtained respectively. The translation information may include the moving distance and moving direction of the terminal, where the moving direction refers to the left or right moving direction of the terminal when moving horizontally, or the upward or downward moving direction when the terminal moves vertically.

In an optional implementation manner of this embodiment, the translation information may also include vertical translation information. In this embodiment, the vertical translation information may be used to describe the movement of the terminal in a direction perpendicular to the screen. Usually, when the user observes the picture displayed on the terminal, the terminal will not make violent movements in the vertical direction. However, in some special cases, for example, when the user is walking while holding the mobile terminal, the position of the mobile terminal itself is in an unstable state. At this time, in order to avoid strong shaking of the picture, the display position of the picture may not be adjusted.

According to the above content, optionally, in the screen display method for a mobile terminal in this embodiment, it may also include:

Step 203, determine whether to adjust the display position of the picture according to the vertical translation information.

In this embodiment, if the vertical translation information of the terminal is obtained in the above step 202, it may be further determined whether to adjust the display position of the screen based only on the moving distance or moving direction in the vertical translation information. For example, when the moving direction does not change within a certain period of time, it indicates that the terminal continues to move in the vertical direction. At this time, it may be considered inappropriate to adjust the display position of the screen.

In an optional implementation of this embodiment, determining whether to adjust the display position of the picture according to the vertical translation information includes: determining to adjust the display position of the picture if the moving distance in the vertical translation information is less than or equal to a first distance threshold. Specifically, if the movement distance in the vertical translation information is less than or equal to the preset first distance threshold, it indicates that the movement distance of the terminal in the vertical direction is relatively small. At this time, it is suitable to adjust the display position of the picture, so it can be determined to adjust the display position of the picture, so as to execute step 204 . Otherwise, reacquire the vertical translation information of the terminal, and perform step 203 again.

Finally, in step 204, the horizontal and vertical display positions of the screen are adjusted based on the horizontal and vertical translation information respectively.

In this embodiment, when the horizontal and vertical translation information of the terminal is obtained in the above step 202, or optionally, after the display position of the adjusted screen is determined in the above step 203, the horizontal display of the screen can be adjusted according to the horizontal translation information Position, and adjust the vertical display position of the screen according to the vertical translation information. Specifically, the horizontal display position of the screen may be adjusted according to the moving distance and moving direction in the horizontal translation information. At the same time, the vertical display position of the screen can be adjusted according to the moving distance and moving direction in the vertical translation information. It should be noted that when the display position of the screen is adjusted based on the moving distance and moving direction of the terminal, the moving distance of the screen is the moving distance of the terminal, and the moving direction of the screen is opposite to the moving direction of the terminal.

In an optional implementation manner of this embodiment, adjusting the horizontal and vertical display positions of the screen based on the horizontal and vertical translation information respectively includes: when the movement distance in the horizontal translation information is greater than the second distance threshold, according to the horizontal translation information in the Adjust the horizontal display position of the screen. When the moving distance in the vertical translation information is greater than the third distance threshold, adjust the vertical display position of the screen according to the moving distance and moving direction in the vertical translation information. Specifically, before adjusting the horizontal display position of the screen, it may first be determined whether the moving distance in the horizontal translation information is greater than the second distance threshold. If the moving distance is greater than the second distance threshold, it can be considered that the terminal has performed horizontal translation, and the screen can be further moved according to the moving distance and moving direction in the horizontal translation information to adjust the horizontal display position of the screen. On the contrary, if the moving distance is less than the second distance threshold, it can be considered that the terminal has not moved laterally, but it is likely to be a normal shaking that occurs when the user holds the terminal, so it is determined not to adjust the display position of the screen. Similarly, it may be determined whether to adjust the vertical display position of the screen according to the magnitude relationship between the moving distance in the vertical translation information and the third distance threshold. It should be noted that the above-mentioned specific values of the second distance threshold and the third distance threshold can be set by the user according to actual needs, and the values of the two can be the same or different, which is not limited in this application.

It can be seen from FIG. 2 that this embodiment further describes in detail an exemplary implementation of a screen display method for a mobile terminal when the offset information includes translation information. This embodiment can first detect whether the picture currently displayed by the terminal exceeds the display range of its screen, and if so, monitor the translation information of the terminal, and adjust the display position of the picture on the terminal screen according to the translation information. By panning the mobile terminal, the display position of the screen on the terminal can be changed. This operation mode is simple and intuitive, and further optimizes the operation efficiency of the terminal screen.

In order to better understand the solution of this embodiment, FIG. 3 shows a schematic diagram of an application scenario of this application. In the scenario shown in FIG. 3 , the terminal 301 is a smart phone. In order to facilitate the description of the translation direction in this embodiment, a Cartesian coordinate system can first be established on the plane where the screen 302 of the terminal 301 is located, wherein the x-axis represents the horizontal direction, the y-axis represents the vertical direction, and the z-axis represents the vertical direction. After the user enables the screen magnification function on the terminal 301 , the screen 303 currently displayed on the terminal 301 can be enlarged so that it exceeds the display range of the screen 302 . At this time, the movement of the terminal in the three directions of x, y and z axes may be collected at a predetermined frequency (for example, 1 time per second), including the movement distance and movement direction. Then, it may first be determined whether the moving distance of the terminal 301 on the z-axis is less than or equal to a preset threshold. If yes, the screen 303 is moved according to the moving distance of the terminal 301 on the x-axis and the y-axis. For example, if the terminal 301 moves 1 centimeter along the positive direction of the x-axis and 2 centimeters along the negative direction of the y-axis at the same time, the image 303 can be moved 1 centimeter along the negative direction of the x-axis and 2 centimeters along the positive direction of the y-axis .

Further referring to FIG. 4 , it shows a flow 400 of another embodiment of a screen display method for a mobile terminal.

As shown in FIG. 4, in step 401, it is detected whether the currently displayed image exceeds the screen display range of the terminal. In this embodiment, this step is the same as the above-mentioned step 101 and will not be repeated here.

Compared with the embodiment shown in FIG. 1 , this embodiment monitors the spin information of the terminal. Optionally, before monitoring the spin information, step 402 may also be included.

Specifically, in step 402, the spin reference position of the terminal is determined according to preset rules.

In this embodiment, after it is determined that the picture exceeds the display range of the terminal screen, the spin reference position may be first determined for the terminal according to certain preset rules. For example, the position when the terminal screen is in a horizontal state can be used as the spin reference position, or the position when the terminal screen and the ground plane form a certain angle (such as 45 degrees) can be used as the spin reference position.

In an optional implementation manner of this embodiment, determining the spin reference position of the terminal according to a preset rule includes: taking a position at which the terminal acquires a predetermined image as the spin reference position. In this embodiment, since each user has a different habit of using a terminal, the viewing angles of the terminal held by the user are also different. Therefore, a personalized spin reference position can be set for each user, so as to improve the applicability of this embodiment. Specifically, the front-facing camera of the terminal can acquire a predetermined image, such as the user's face image or eye image, etc. At this time, it can be considered that the terminal is facing the terminal for observation, so it can be used as the spin reference position of the terminal.

Then, in step 403, if the screen display range of the terminal is exceeded, the spin information of the terminal is monitored.

In this embodiment, when it is detected in the above step 401 that the currently displayed image exceeds the screen display range of the terminal, the spin information of the terminal is monitored. In this embodiment, the spin information may include horizontal and vertical spin information, where the horizontal and vertical directions may refer to two directions perpendicular to each other in the plane where the terminal screen is located. Generally, the orientations of two adjacent sides of the rectangular screen can be set as landscape and portrait respectively. Specifically, when monitoring the spin information of the terminal, the spin information of the terminal in the horizontal direction and the vertical direction can be obtained respectively. The spin information may include the spin angle and spin direction of the terminal, where the transverse direction in the spin direction refers to the clockwise or counterclockwise rotation direction of the terminal around the longitudinal axis, and the longitudinal direction in the spin direction refers to the direction of rotation of the terminal Direction of rotation clockwise or counterclockwise about the transverse axis.

If the spin reference position of the terminal is determined in the above optional step 402, step 403A may be included in this step 403.

Specifically, in step 403A, based on the aforementioned spin reference position, the spin information of the terminal is monitored. In this embodiment, when the terminal monitors the spin information, it can always use the aforementioned spin reference position as a starting position to determine the spin angle and spin direction of the terminal. Therefore, the spin state is always based on the same position, so that the movement information of the screen can be obtained through the spin information.

Optionally, the screen display method in this embodiment may further include step 404 .

Specifically, in step 404, it is determined whether to adjust the display position of the picture according to the change of the spin information.

In this embodiment, if the spin information of the terminal is obtained through monitoring based on the spin reference position in the above step 403A, it may be further determined whether to adjust the display position of the screen according to changes in the spin information. Specifically, when the terminal is rotated, the terminal screen used to present the picture is deflected, which is inconvenient for the user to observe the image. In order to improve this problem, the spin reference position can be taken as the most suitable observation position, and then it is determined whether to adjust the display position of the picture according to the change of the spin information. For example, when it is determined through the spin information that the terminal turns away from the spin reference position, it means that the user wants to change the display position of the screen through the spin of the terminal, and then determine to adjust the display position of the screen; and when it is determined through the spin information that the terminal rotates from other positions When returning to the reference position of the spin, it indicates that the user wishes to observe the screen after the display position changes, and then it is determined not to adjust the display position of the screen. That is to say, when the terminal returns to the spin reference position from a certain position, the adjusted image at the position may still be displayed instead of the initial image at the spin reference position. In this way, not only can the display position of the image be adjusted by spinning, but also solve the problem that the screen deflects after spinning, which is not conducive to user observation, and further improves the practicability of the method.

In an optional implementation manner of this embodiment, determining whether to adjust the display position of the picture according to changes in the spin information includes: determining to adjust the display position of the picture if the spin angle in the spin information gradually increases. Specifically, when determining whether to adjust the display position of the picture, the spin direction may not be considered, but only the change of the spin angle. If the spin angle continues to increase, it means that the terminal is gradually turning away from the spin reference position, and it can be determined that the user wants to change the display position of the screen through the spin of the terminal. Conversely, if the spin angle keeps decreasing, it means that the terminal gradually turns back to the spin reference position from other positions, and it can be determined that the user wants to observe the screen after the display position changes. In this process, it can be determined not to adjust the display position of the picture.

Finally, in step 405, the horizontal and vertical display positions of the picture are adjusted based on the horizontal and vertical spin information respectively.

When the horizontal and vertical spin information of the terminal is obtained in the above step 403, or optionally, after determining to adjust the display position of the screen in the above step 405, the horizontal display position of the screen can be adjusted according to the horizontal spin information, and according to The vertical rotation information adjusts the vertical display position of the screen. Specifically, the horizontal display position of the picture may be adjusted according to the spin angle and spin direction in the horizontal spin information. At the same time, the vertical display position of the picture can be adjusted according to the spin angle and spin direction in the vertical spin information. It should be noted that when adjusting the display position of the screen based on the spin angle and spin direction of the terminal, the moving distance of the screen can be determined according to the spin angle of the terminal, and the moving direction of the screen can be determined according to the spin direction of the terminal .

In an optional implementation manner of this embodiment, adjusting the horizontal and vertical display positions of the picture based on the horizontal and vertical translation information respectively includes: when the spin angle in the horizontal spin information is greater than the first angle threshold, according to the horizontal spin According to the spin angle and spin direction in the spin information, adjust the horizontal display position of the screen; when the spin angle in the vertical spin information is greater than the second angle threshold, according to the spin angle and spin direction in the vertical spin information to adjust the vertical display position of the screen. Specifically, before adjusting the horizontal display position of the screen, it may first be determined whether the spin angle in the horizontal spin information is greater than the first angle threshold. If the spin angle is greater than the first angle threshold, it can be considered that the terminal has performed horizontal spin, and the screen can be further moved according to the spin angle and spin direction in the horizontal spin information to adjust the horizontal display position of the screen. On the contrary, if the spin angle is smaller than the first angle threshold, it can be considered that the terminal is not spinning horizontally, but it is likely to be a normal shaking that occurs when the user holds the terminal, so it is determined not to adjust the display position of the screen. Similarly, it may be determined whether to adjust the vertical display position of the picture according to the magnitude relationship between the spin angle in the vertical spin information and the second angle threshold. It should be noted that the above-mentioned specific values of the first angle threshold and the second angle threshold can be set by the user according to actual needs, and the values of the two can be the same or different, which is not limited in this application.

In an optional implementation manner of this example, adjusting the display position of the picture according to the above spin angle and spin direction may include: determining the movement distance of the picture according to the spin angle and a preset weight; determining the movement distance of the picture according to the spin direction and adjust the display position of the screen according to the moving distance and moving direction. When the terminal spins, it is necessary to determine the moving distance of the picture according to the spin angle. Specifically, a weight ξ may be preset first, and the weight may be determined according to historical experience, or may be determined according to the size of the current picture. For example, assuming that the horizontal width and vertical height of the picture are w and h respectively, and the maximum spin angle of the terminal is 90 degrees, then the horizontal weight ξx can be w/90, and the vertical weight ξy can be h/90. The moving distance of the screen and the screen offset distance can be determined according to the following formula:

(dx,dy)=(ξx·αx,ξy·αy)

Wherein, dx and dy respectively represent the movement distance of the screen in the horizontal and vertical directions, and αx and αy represent the horizontal and vertical spin angles of the terminal, respectively. The moving direction of the screen can be determined according to the spin direction of the terminal. Specifically, the relationship between the rotating direction and the moving direction of the screen can be defined by the user. For example, the screen can be defined to move forward when spinning clockwise. After determining the moving distance and moving direction of the picture, the display position of the picture can be adjusted.

It should be noted that, although operations of the methods of the present invention are depicted in the drawings in a particular order, this does not require or imply that the operations must be performed in that particular order, or that all illustrated operations must be performed to achieve the desired results. . Conversely, some of the steps depicted in the flowcharts may be performed in altered order. For example, in FIG. 4, the execution order of step 402 may not be specific to that shown in FIG. 4, as long as the spin reference position is determined in step 402 before the spin information of the terminal is monitored in step 403, it will not affect the image display method of the present invention realization. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step for execution, and/or one step may be decomposed into multiple steps for execution.

It can be seen from FIG. 4 that this embodiment further describes in detail an exemplary implementation of a screen display method for a mobile terminal when the offset information includes spin information. In this embodiment, it is possible to first detect whether the picture currently displayed by the terminal exceeds the display range of its screen, and if so, monitor the spin information of the terminal, and adjust the display position of the picture on the terminal screen according to the spin information. By spinning the mobile terminal, the display position of the screen on the terminal can be changed. This operation method is simple and efficient, and further expands the scope of application of the screen display method of the present application.

In order to better understand the solution of this embodiment, the application scenario of the present application shown in FIG. 3 is also taken as an example for specific description. In the scene shown in FIG. 3 , a Cartesian coordinate system has been established on the plane where the screen 302 of the terminal 301 is located, where the x-axis represents the horizontal direction and the y-axis represents the vertical direction. Then, when obtaining the spin information of the terminal, the spin around the x-axis can be regarded as the longitudinal spin, and the spin around the y-axis can be regarded as the transverse spin. At the same time, the relationship between the moving direction of the picture and the spin direction can be defined. For example, when viewed along the negative direction of the y-axis, if the terminal 301 rotates clockwise around the y-axis, the picture can move along the positive direction of the x-axis, otherwise, the picture can move along the negative direction of the x-axis. Similarly, when viewed along the positive direction of the x-axis, if the terminal 301 spins clockwise around the x-axis, the picture can move along the positive direction of the y-axis, otherwise, the picture can move along the negative direction of the y-axis. After the screen 303 currently displayed by the terminal 301 is enlarged through the screen zoom-in function, horizontal and vertical spin information of the terminal, including spin angle and spin direction, can be collected at a predetermined frequency (for example, 5 times/second). When the spin angle gradually increases and is greater than the angle threshold of 5 degrees, it is determined to adjust the display position of the picture. Specifically, if the spin angle of the terminal 301 rotating clockwise around the y-axis gradually increases from 0 to 30 degrees, the distance dx that the screen 303 moves along the positive direction of the x-axis can be calculated according to the following formula:

dx=ξx·αx=(w/90)·30=w/3

Wherein, ξx is the horizontal weight, αx is the horizontal spin angle of the terminal 301 , and w is the horizontal width of the picture 303 . At this time, if the spin angle gradually decreases from 30 degrees to 0 degrees, it is determined not to adjust the display position of the picture. Therefore, when the terminal 301 turns back to 0 degrees, the screen 303 still maintains the state after moving w/3 along the positive direction of the x-axis. If the terminal 303 repeats from 0 degrees to 30 degrees and then back to 0 degrees again, the screen 303 may be at a position after moving 2w/3 along the positive direction of the x-axis. Similarly, when the terminal 301 spins counterclockwise around the y-axis, the picture 303 can be moved along the negative direction of the x-axis. Those skilled in the art can understand that the situation when the terminal 301 spins around the x-axis is similar to the situation when the terminal 301 spins around the y-axis, and will not be repeated here.

In an optional implementation of this embodiment, the terminal may adjust the display position of the screen based on the translation information and the spin information, specifically including: adjusting the horizontal display position of the screen based on the horizontal translation information and the horizontal spin information; Information and vertical rotation information to adjust the vertical display position of the screen. In this embodiment, the terminal can obtain the translation information and the spin information at the same time, and adjust the display position of the picture according to the common changes of the two. The specific process of obtaining the translation information or spin information and determining the moving distance of the screen according to the translation information or spin information can be implemented according to the steps described in the above embodiments, and will not be repeated here. If the moving distance of the picture is determined to be (Δx, Δy) according to the translation information, and (dx, dy) is determined to be the moving distance of the picture according to the spin information, the actual offset of the picture can be obtained by adding the two vectors, namely (Sx,Sy)=(Δx+dx,Δy+dy). At the same time, in order to avoid that the actual moving distance of the screen exceeds the adjustable range of the screen, it is necessary to update the relative position of the screen and the edge of the screen in real time. Also specifically take the application scenario shown in FIG. 3 as an example for description. As shown in FIG. 3 , the distances from the top, bottom, left, and right edges of the screen 303 to the edges of the screen 302 are respectively Y1, Y2 and X1, X2. At this time, the maximum distance that the picture moves along the positive direction of the x-axis is X2. If it is determined according to the translation information and the spin information that the moving distance of the picture along the positive direction of the x-axis is greater than X2, X2 is taken as the moving distance of the picture. Similarly, screen movement in other directions will not exceed the edge of the screen. In this embodiment, the translation information and the spin information of the terminal can be acquired at the same time, and the display position of the picture can be adjusted according to it, which further improves the flexibility of the picture display method of the present application.
