【Detailed ways】

As shown in Figure 1, in one embodiment, a method for displaying a screen display image of a mobile terminal includes the following steps:

Step S102, acquiring an instruction to zoom out and pan the screen display image.

The screen in this application document is a touch screen. The screen display image is an overall image displayed in the screen display area, including a task bar, a message notification bar, and a user interface.

Step S104, judging whether the holding mode of the mobile terminal is a left-handed mode or a right-handed mode.

If the holding mode is the left-handed mode, it indicates that the user holds the mobile terminal with the left hand; correspondingly, if the holding mode is the right-handed mode, it indicates that the user holds the mobile terminal with the right hand.

Step S106, shrinking the screen display image according to a preset ratio, and if the holding mode is left-handed mode, then shifting the screen display image to the lower left corner of the screen, and if the holding mode is right-handed mode, then moving the screen display image to the right of the screen Pan the bottom corner.

In one embodiment, the entire screen display image may be reduced according to a preset ratio, for example, reduced to three quarters of the original size of the screen display image. Specifically, a traditional image reduction processing method may be used to reduce the screen display image, for example, a sampling method, an averaging method, a bilinear method, and the like.

This application document describes the orientation based on the situation that the mobile terminal is placed upright with its screen facing the user. Wherein, the left and right orientation is based on the left and right orientation of the user, and the up and down orientation is based on the up and down orientation sensed by the gravity sensor. For example, the lower left corner of the screen refers to the lower screen corner on the same side as the user's left hand when the screen of the mobile terminal faces the user.

Specifically, in step S106, the center point of the screen display screen can be used as a reference, and the preset x length can be translated downward, and the preset y length can be translated to the left if the holding mode is the left-handed mode; if the holding mode is the right-handed mode, then Translates to the right by the preset y-length.

As shown in FIG. 2A , when the holding mode is the left-handed mode, the screen display image 202 that originally occupies the screen 201 is translated to the lower left corner of the screen. As shown in FIG. 2B , when the holding mode is the right hand mode, the screen display image 202 that originally occupies the screen 201 is translated to the lower right corner of the screen.

In the method for displaying the screen display of the above-mentioned mobile terminal, after obtaining the instructions for zooming out and panning the screen display, it is judged whether the holding mode of the mobile terminal is the left-handed mode or the right-handed mode, and the screen display is reduced according to a preset ratio, and If the holding mode of the mobile terminal is the left-handed mode, then the screen display is translated to the lower left corner of the screen; Still in the right-hand mode, the screen range that can be touched by the hand holding the mobile terminal can be increased, so that it is convenient to hold and touch the mobile terminal with one hand.

As shown in FIG. 3A, in one embodiment, before step S102, the method for displaying the screen display of the above-mentioned mobile terminal further includes:

Step S101 , when an upward sliding operation starting from the non-display area below the display area of the touch screen occurs, triggering the above-mentioned instructions of zooming out and panning the displayed screen.

Specifically, in one embodiment, as shown in FIG. 3B, the step S101 includes the following steps:

Step S302, monitoring the sliding operation on the touch screen.

In one embodiment, a gesture monitoring interface in the system may be invoked to monitor the sliding operation on the touch screen. For example, an On Gesture Listener interface or a Gesture Detector interface is called to monitor the sliding operation of the touch screen in the Android system (a Linux-based free and open source operating system mainly used in mobile devices).

Step S304, when a sliding operation occurs on the touch screen, record the sliding track generated by the sliding operation.

In one embodiment, the coordinates of the touch point of the sliding operation can be obtained through the movement event object, for example, in the Android system, the coordinates of the touch point can be obtained through the MotionEvent object. The MotionEvent object records the coordinates of the touch point. As the position of the touch point changes during the sliding operation, the coordinates of the touch point recorded by the MotionEvent object also change. Save the coordinates recorded by the MotionEvent object and form a coordinate sequence. The points corresponding to the coordinate sequence can form the sliding track corresponding to the sliding operation.

The coordinates in this application document refer to the coordinates in the coordinate system established with the line parallel to the bottom edge of the display area (consisting of the bottom row of pixels) as the x-axis and the line perpendicular to the x-axis as the y-axis .

In step S306, it is judged according to the sliding track whether the sliding operation starts from the non-display area below the display area of the touch screen and the direction is upward.

In one embodiment, the step of judging whether the sliding operation starts from the non-display area below the display area of the touch screen according to the sliding track includes: judging whether the starting point of the sliding track is located near the bottom of the display area of the touch screen, and if so, determining whether the sliding operation starts from the bottom of the display area of the touch screen. The non-display area below the display area starts, otherwise, it is determined that the sliding operation does not start from the non-display area.

The touch screen includes a touch area and a display area. The touch area is used to receive a signal input by a contact (such as a stylus, finger, etc.), and the display area is used to display a picture. The touch area and display area of some touch screens overlap; while the touch area of some touch screens covers the display area and extends a part outward. Generally, a part extends below the display area, and this part can be used to place some fixed icons. , such as returning to the previous interface icon, returning to the desktop icon, menu icon, etc., wherein, when the returning to the previous interface icon is clicked, the command to return to the previous interface can be triggered, and when the returning to the desktop icon is clicked, the command to return to the desktop can be triggered, and the menu icon A command that triggers the display of the menu when clicked.

Therefore, when the touch area of the touch screen overlaps with the display area, the non-display area below the display area is not included in the touch area; when the touch area of the touch screen covers the display area and extends a part below it, the area below the display area The non-display area includes or is partially included in the touch area.

In one embodiment, when the touch area of the touch screen overlaps with the display area, since touch operations outside the display area cannot be detected, it can be determined whether the starting point of the sliding track is located at the bottom of the display area. If the starting point of the sliding track is located at the bottom of the display area, it is determined that the sliding operation starts from the non-display area below the display area. Because in the actual operation process, if the actual sliding operation starts from the non-display area below the display area and does not break away from the touch screen during the entire sliding operation process, the starting point of the monitored sliding track must be located at the bottom of the display area .

In another embodiment, when the touch area of the touch screen overlaps with the display area, it can be judged whether the starting point of the sliding track is lower than a preset position above the bottom edge of the display area, and the preset position is the same as the bottom edge of the display area. The vertical distance differs by several pixels (equivalent to a vertical distance close to 0), and if so, it is determined that the sliding operation starts from the non-display area below the display area. Since the vertical distance between the preset position and the bottom edge is only a few pixels, it is almost impossible to locate the starting point of the sliding operation between the bottom edge of the display area and the preset position during actual operation. Only by sliding up from the non-display area below the display area can the starting point of the sliding track be lower than the preset position above the bottom of the display area. Therefore, the starting point of the sliding track is lower than the bottom of the display area. The situation of the preset position is determined to be that the sliding operation starts from the non-display area below the display area, which is in line with the actual operation situation.

On the other hand, the upward sliding operation starting from the non-display area may also cause a certain point in the middle to break away from the touch screen, resulting in two sliding trajectories. If the starting point of the second sliding trajectories If it happens to fall between the bottom edge of the display area and the preset position, it is determined that the sliding operation starts from the non-display area below the display area, which is also in line with the actual operation situation, and provides a certain room for error tolerance for the user's operation mistakes.

In one embodiment, when the touch area of the touch screen covers the display area and extends a part below it, since the touch operation within a certain distance below the display area can be detected, it can be judged whether the starting point of the sliding track is lower than the display area If it is, then it is determined that the sliding operation starts from the non-display area below the display area.

Specifically, in one embodiment, when the touch area of the touch screen overlaps with the display area, it can be determined whether the ordinate of the starting point of the sliding track is equal to the ordinate of the bottom edge of the display area, and if so, it is determined that the sliding operation starts from the display area. Alternatively, it can be judged whether the ordinate of the starting point of the sliding track is smaller than the sum of the ordinate of the bottom edge of the display area and the distance of several pixels. Display area departure. The distance of several pixels refers to the distance represented by several consecutive pixels arranged in a straight line in the coordinate system.

When the touch area of the touch screen covers the display area and extends a part below it, it can be judged whether the vertical coordinate of the starting point of the sliding track is smaller than the vertical coordinate of the bottom edge of the display area, and if so, it is determined that the sliding operation starts from the bottom of the display area. Depart from the non-display area.

For example, take the pixel point in the lower left corner of the display area as the origin of the coordinates, take the line of the row of pixels at the bottom of the display area as the x-axis, and take the line of the leftmost row of pixels in the display area as the y-axis to establish a two-dimensional coordinate system (hereinafter referred to as the coordinate system xoy), wherein the direction of the x-axis is from left to right, and the direction of the y-axis is from right to left.

When the touch area of the touch screen overlaps with the display area, it can be judged whether the vertical coordinate of the starting point of the sliding track is equal to 0, and if so, it is determined that the sliding operation starts from the non-display area below the display area; or, the starting point of the sliding track can be judged Whether the ordinate of the starting point is less than the distance of several pixels, if so, it is determined that the sliding operation starts from the non-display area below the display area.

When the touch area of the touch screen covers the display area and extends a part below it, it can be determined whether the vertical coordinate of the starting point of the sliding track is less than 0, and if so, it is determined that the sliding operation starts from the non-display area below the display area.

In one embodiment, it may be determined whether the distance between the abscissa of the starting point of the sliding track and the abscissa of the ending point is less than a third threshold, and if so, it is determined that the direction of the sliding operation is upward.

Step S308 , when the sliding operation starts from the non-display area and the direction is upward, the above-mentioned instruction of zooming out and panning the displayed screen is triggered.

The above-mentioned embodiment monitors the sliding operation on the touch screen and records the corresponding sliding track. When the sliding operation starts from the non-display area below the display area of the touch screen and the direction is upward, the above-mentioned instructions for zooming out and panning the screen display screen are triggered, and It is not necessarily necessary to be limited to tangible icons to trigger instructions, thereby saving space occupied by tangible icons.

In one embodiment, step S101 further includes the step of: judging according to the sliding track whether the upward displacement of the sliding operation is greater than the first threshold; in step S101, when the sliding operation starts from the non-display area, the upward direction and the upward displacement are greater than the first threshold , the above-mentioned commands for zooming out and panning the screen display image are triggered. FIG. 4 shows an execution flow of step S101 in this embodiment. As shown in Figure 4, step S101 includes the following steps:

Step S402, monitoring the sliding operation on the touch screen.

Step S404, when a sliding operation occurs on the touch screen, record the sliding track generated by the sliding operation.

Step S406 , judging whether the sliding operation starts from the non-display area below the display area of the touch screen in an upward direction according to the sliding track, and judging whether the upward displacement of the sliding operation is greater than a first threshold.

Specifically, the upward displacement of the sliding operation may be calculated as the distance between the ordinate of the starting point and the ordinate of the ending point of the sliding track.

Step S408 , when the sliding operation starts from the non-display area, the direction is upward, and the upward displacement is greater than the first threshold, triggering the above-mentioned instruction of zooming out and panning the displayed screen.

In the above embodiment, when the sliding operation starts from the non-display area, the direction is upward and the upward displacement is greater than the first threshold, the command to zoom out and pan the screen display is triggered, and some upward but upward movement from the non-display area can be filtered out. Unintentional operations with small displacements, and avoid these operations triggering commands to zoom out and pan the screen display.

In another embodiment, the above step S101 further includes the step of: monitoring whether the time that the sliding operation stays at the termination point of the sliding operation exceeds the second threshold; When whether the staying time at the end point of the sliding operation exceeds the second threshold, the above-mentioned instruction of zooming out and panning the displayed screen is triggered. FIG. 5 shows an execution flow of step S101 in this embodiment. As shown in Figure 5, step S101 includes the following steps:

Step S502, monitoring the sliding operation on the touch screen.

Step S504, when a sliding operation occurs on the touch screen, record the sliding track generated by the sliding operation.

Step S506 , judging whether the sliding operation starts from the non-display area below the display area of the touch screen with an upward direction according to the sliding track, and monitoring whether the time for the sliding operation to stay at the end point of the sliding operation exceeds a second threshold.

In one embodiment, the step of monitoring whether the time that the sliding operation stays at the end point of the sliding operation exceeds a second threshold includes the following steps: monitoring whether the touch point of the sliding operation stays at the same place, and if so, recording the touch point The start time of the point stay (that is, the position of the touch point no longer changes), and calculate the length of time the touch point stays here, and monitor whether the touch point stays here and does not move to other places for sliding operations. Termination, if the sliding operation stays here for longer than the second threshold and the touch point does not move to other places after staying here and the sliding operation is terminated, then it is determined that the sliding operation has stayed at the termination point of the sliding operation for more than the second threshold. Otherwise, it is determined that the time that the sliding operation stays at the termination point of the sliding operation does not exceed the second threshold.

Step S508 , when the sliding operation starts from the non-display area, moves upward and stays at the end point of the sliding operation for more than a second threshold, trigger the above-mentioned instruction of zooming out and panning the displayed screen.

In the above-mentioned embodiment, when the sliding operation starts from the non-display area, the direction is upward, and the time spent at the end point of the sliding operation exceeds the second threshold, the command to zoom out and pan the screen display screen is triggered, which can filter out some Involuntary operations starting from the non-display area but staying at the end point for a short period of time prevent these operations from triggering commands to zoom out and pan the screen display.

In one embodiment, in step S101, when the sliding operation starts from the non-display area, the direction is upward, and the upward displacement is greater than the first threshold and the time spent at the end point of the sliding operation exceeds the second threshold, the above-mentioned commands for zooming out and panning the screen display.

In one embodiment, the steps of judging whether the holding mode of the mobile terminal is the left-handed mode or the right-handed mode are:

It is judged that the above-mentioned sliding operation of triggering the instruction of zooming out and panning the screen display is close to the left side or the right side of the mobile terminal. If it is close to the left side of the mobile terminal, it is determined that the holding mode of the mobile terminal is left-handed mode. If it is close to the right side of the mobile terminal, Then it is determined that the holding mode of the mobile terminal is the right hand mode.

In one embodiment, based on the above coordinates, the coordinates of the starting point of the sliding track corresponding to the sliding operation can be obtained, and it is judged whether the abscissa of the coordinates of the starting point is smaller than the abscissa of the center point of the screen, and if so, it is determined whether the abscissa of the mobile terminal is The holding mode is the left-handed mode; otherwise, it is determined that the holding mode of the mobile terminal is the right-handed mode.

In another embodiment, the step of judging whether the holding mode of the mobile terminal is left-hand mode or right-hand mode is:

It is judged whether the holding mode of the mobile terminal is a left-handed mode or a right-handed mode through the holding sensor of the mobile terminal.

A grip sensor (grip sensor) can determine whether the grip mode of the mobile terminal is a left-handed mode or a right-handed mode by detecting different capacitance values generated when the mobile terminal is held by the left hand and the right hand. Generally, the grip sensor includes multiple sensing electrodes and at least one sensing chip. The sensing electrodes are arranged on the back of the mobile terminal. After the mobile terminal is held by the hand, a capacitance will be formed between the hand and the electrodes. The mobile terminal will generate different capacitance values; the sensor chip can detect the generated capacitance value, and determine the posture of the hand holding according to the capacitance value, that is, determine whether the holding mode of the mobile terminal is left-handed or right-handed. The grip sensor in the present invention can adopt the AD7146 and AD714x sensors of ADI (Analog Devices, Inc., Analog Devices Semiconductor Technology (Shanghai) Co., Ltd.).

In one embodiment, the above method for displaying the screen display of the mobile terminal further includes a step of: filling the screen area not covered by the shrinking and shifting of the screen display with a preset color.

After the image displayed on the screen is zoomed out and shifted according to step S106, a part of the image is moved out of the screen area, and only a part of the image remains displayed in the screen area. Allows you to fill areas of the screen outside the partial frame coverage of this display with a preset color.

Since it is only meaningful to operate the icons on the screen through the touch screen, the screen area outside the coverage of the displayed part of the screen is an invalid touch area. Filling the area with a preset color can make this part of the screen area an invalid touch area. The role of the region.

As shown in FIG. 6, in one embodiment, a display device for displaying images on a screen of a mobile terminal includes an instruction acquisition module 602, a grip mode judgment module 604, a screen reduction module 606, and a screen translation module 608, wherein:

The instruction obtaining module 602 is used to obtain instructions for zooming out and panning the displayed images on the screen.

The screen in this application document is a touch screen. The screen display image is an overall image displayed in the screen display area, including a task bar, a message notification bar, and a user interface.

The holding mode judging module 604 is used for judging whether the holding mode of the mobile terminal is a left-handed mode or a right-handed mode.

If the holding mode is the left-handed mode, it indicates that the user holds the mobile terminal with the left hand; correspondingly, if the holding mode is the right-handed mode, it indicates that the user holds the mobile terminal with the right hand.

The image reduction module 606 is used to reduce the screen display image according to a preset ratio.

In one embodiment, the image reduction module 606 may reduce the entire screen display image according to a preset ratio, for example, to three quarters of the original size of the screen display image. Specifically, a traditional image reduction processing method may be used to reduce the screen display image, for example, a sampling method, an averaging method, a bilinear method, and the like.

The picture translation module 608 is used to translate the screen display picture to the lower left corner of the screen if the holding mode is the left hand mode, and translate the screen display picture to the lower right corner of the screen if the holding mode is the right hand mode. This application document describes the orientation based on the situation that the mobile terminal is placed upright with its screen facing the user. Wherein, the left and right orientation is based on the left and right orientation of the user, and the up and down orientation is based on the up and down orientation sensed by the gravity sensor. For example, the lower left corner of the screen refers to the lower screen corner on the same side as the user's left hand when the screen of the mobile terminal faces the user.

Specifically, the picture translation module 608 can use the center point of the screen display picture as a reference to translate the preset x length downwards, and if the holding mode is the left-handed mode, then translate the preset y length to the left; if the holding mode is the right hand mode shifts to the right by the preset y length.

The above-mentioned display device of the screen display screen of the mobile terminal, after obtaining the instruction of zooming out and panning the screen display screen, judges whether the holding mode of the mobile terminal is left-handed mode or right-handed mode, and shrinks the screen display screen according to a preset ratio, and If the holding mode of the mobile terminal is the left-handed mode, then the screen display is translated to the lower left corner of the screen; Still in the right-hand mode, the screen range that can be touched by the hand holding the mobile terminal can be increased, so that it is convenient to hold and touch the mobile terminal with one hand.

As shown in FIG. 7A, in one embodiment, the above-mentioned display device for displaying images on the screen of the mobile terminal further includes an instruction trigger module 601, which is used for starting from the non-display area below the display area of the touch screen and moving upwards. When the slide operation is performed, the above-mentioned instructions for zooming out and panning the screen display image are triggered.

Specifically, in one embodiment, as shown in FIG. 7B , the instruction triggering module 601 includes a monitoring unit 702, a trajectory recording unit 704, a starting point and direction judging unit 706, and an instruction triggering unit 708, wherein:

The monitoring unit 702 is used for monitoring the sliding operation on the touch screen.

In one embodiment, the monitoring unit 702 can call a gesture monitoring interface in the system to monitor the sliding operation on the touch screen. For example, an On Gesture Listener interface or a Gesture Detector interface is called to monitor the sliding operation of the touch screen in the Android system (a Linux-based free and open source operating system mainly used in mobile devices).

The track recording unit 704 is configured to record the sliding track generated by the sliding operation when the sliding operation occurs on the touch screen.

In one embodiment, the track recording unit 704 can obtain the coordinates of the touch point of the sliding operation through the movement event object, for example, in the Android system, the coordinates of the touch point can be obtained through the MotionEvent object. The MotionEvent object records the coordinates of the touch point. As the position of the touch point changes during the sliding operation, the coordinates of the touch point recorded by the MotionEvent object also change. Save the coordinates recorded by the MotionEvent object and form a coordinate sequence. The points corresponding to the coordinate sequence can form the sliding track corresponding to the sliding operation.

The coordinates in this application document refer to the coordinates in the coordinate system established with the line parallel to the bottom edge of the display area (consisting of the bottom row of pixels) as the x-axis and the line perpendicular to the x-axis as the y-axis .

The starting point and direction judging unit 706 is used to judge whether the sliding operation starts from the non-display area below the display area of the touch screen and the direction is upward according to the sliding track.

In one embodiment, the starting point and direction judging unit 706 is used to judge whether the starting point of the sliding track is located near the bottom of the display area of the touch screen to distinguish whether the sliding operation starts from the non-display area below the display area of the touch screen, if the sliding track is located near the bottom of the display area, it is determined that the sliding operation starts from the non-display area below the display area; otherwise, it is determined that the sliding operation does not start from the non-display area.

The touch screen includes a touch area and a display area. The touch area is used to receive a signal input by a contact (such as a stylus, finger, etc.), and the display area is used to display a picture. The touch area and display area of some touch screens overlap; while the touch area of some touch screens covers the display area and extends a part outward. Generally, a part extends below the display area, and this part can be used to place some fixed icons. , such as returning to the previous interface icon, returning to the desktop icon, menu icon, etc., wherein, when the returning to the previous interface icon is clicked, the command to return to the previous interface can be triggered, and when the returning to the desktop icon is clicked, the command to return to the desktop can be triggered, and the menu icon A command that triggers the display of the menu when clicked.

Therefore, when the touch area of the touch screen overlaps with the display area, the non-display area below the display area is not included in the touch area; when the touch area of the touch screen covers the display area and extends a part below it, the area below the display area The non-display area includes or is partially included in the touch area.

In one embodiment, when the touch area of the touch screen overlaps with the display area, since touch operations outside the display area cannot be detected, the start point and direction determination unit 706 can determine whether the start point of the sliding track is located at the bottom of the display area. If the starting point of the sliding track is located at the bottom of the display area, it is determined that the sliding operation starts from the non-display area below the display area. Because in the actual operation process, if the actual sliding operation starts from the non-display area below the display area and does not break away from the touch screen during the entire sliding operation process, the starting point of the monitored sliding track must be located at the bottom of the display area .

In another embodiment, when the touch area of the touch screen overlaps with the display area, the starting point and direction judging unit 706 can judge whether the starting point of the sliding track is lower than a preset position above the bottom edge of the display area. It is assumed that the vertical distance between the position and the bottom edge differs by several pixels (equivalent to a vertical distance close to 0), and if so, it is determined that the sliding operation starts from the non-display area below the display area. Since the vertical distance between the preset position and the bottom edge is only a few pixels, it is almost impossible to locate the starting point of the sliding operation between the bottom edge of the display area and the preset position during actual operation. Only by sliding up from the non-display area below the display area can the starting point of the sliding track be lower than the preset position above the bottom of the display area. Therefore, the starting point of the sliding track is lower than the bottom of the display area. The situation of the preset position is determined to be that the sliding operation starts from the non-display area below the display area, which is in line with the actual operation situation.

On the other hand, the upward sliding operation starting from the non-display area may also cause a certain point in the middle to break away from the touch screen, resulting in two sliding trajectories. If the starting point of the second sliding trajectories If it happens to fall between the bottom edge of the display area and the preset position, it is determined that the sliding operation starts from the non-display area below the display area, which is also in line with the actual operation situation, and provides a certain room for error tolerance for the user's operation errors.
