【detailed description】

The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1, which is a schematic flowchart of a first embodiment of a method for switching between a horizontal and vertical screen according to the present invention.

S101: Determine whether the wearable device is placed horizontally.

In a specific implementation scenario, it is determined whether the wearable device is in a horizontally placed state. The gravity sensor and / or the spirit level can be used to determine whether the wearable device is placed horizontally. Since the wearable device is often in motion when worn on the user, the first sensing range (for example, +/- 10 °, +/- 170 °, etc.) can be set in advance. When the gravity sensor and / or the level gauge determines that the current When the wearable device is within the first sensing range, it can be determined that the wearable device is in a horizontally placed state.

In other implementation scenarios, the user may place the wearable device in a horizontal state and input a recording instruction. The wearable device receives the recording instruction, and records the current state of the gravity sensor in response to the recording instruction, which is a horizontal state. When the wearable device detects that the state of the gravity sensor is consistent or similar to the recorded horizontal state (the error is less than a preset threshold), it is determined that the wearable device is in a horizontally placed state. Further, the wearable device can be placed in the horizontal state multiple times, and the multiple states corresponding to the gravity sensor can be recorded respectively, and the range of the horizontal state can be set according to the corresponding multiple states. When the wearable device detects that the fixed gravity sensor is in When the horizontal state is within the range, it is determined that the wearable device is in a horizontally placed state.

Further, since the wearable device is worn on the user and is often in a sports state, it may be in a horizontal state due to coincidence. At this time, the user does not actually need to view the display content of the display screen of the wearable device. In order to avoid this situation, when the wearable terminal detects that the gravity sensor is in the horizontal state or the range of the horizontal state, if it is detected that the gravity sensor is in the horizontal state or the range of the horizontal state exceeds a preset time length (for example, 1S, 2S, etc.) to determine that the wearable device is placed horizontally.

In another implementation scenario, before determining whether the wearable device is placed horizontally, first determine whether the wearable device has the horizontal and vertical screen switching function enabled, and if the wearable device has the horizontal and vertical screen switching function enabled, then determine the wearable device Whether it is placed horizontally, and follow up the steps. If the wearable device does not enable the horizontal and vertical screen switching function, the current display state of the display screen is maintained. Specifically, the user can enable the horizontal and vertical screen switching function of the wearable device through virtual or physical buttons, or the user can realize the horizontal and vertical screen switching function by waving arms, pressing the screen, and the like.

In another implementation scenario, before determining whether the wearable device is in a horizontally placed state, first determine whether the wearable device is in a use state. Because in actual use, if the wearable device is placed in a backpack or pocket, if it is still turned on, if it is detected that it is in a horizontal or vertical position, the user has not checked the display screen at this time. Because of the content requirements, it is not necessary to switch between the horizontal and vertical screens. Instead, it wastes resources. In order to save resources, the display screen of the wearable device can be turned off. Only when the wearable device is in use, the method for switching between the horizontal and vertical screens is started. For example, the sensor can detect the user's pulse, body temperature, etc. to determine whether the wearable device is in use. Or, whether the user's facial image is captured by the front camera of the wearable device can be turned on to determine whether the wearable device is in use.

S102: If the wearable device is placed horizontally, display the display screen of the wearable device horizontally.

In a specific implementation scenario, if it is determined that the wearable device is in a horizontally placed state, then the display screen of the wearable device is displayed horizontally. The horizontal screen display may be a preset display angle in the wearable device, or may be a display angle adjusted by the user device according to personal usage habits.

In other implementation scenarios, in order to protect the personal privacy of the user, when the landscape is displayed, the display brightness of the display screen may be adjusted to the first brightness and / or the viewing angle of the display screen may be adjusted to the first angle range.

The first brightness may be preset by the user, or may receive multiple adjustments by the user, so as to learn the user's usage habits, so as to obtain the brightness used by the user as the first brightness. In addition, the first brightness can also obtain the brightness of the environment in which the user is currently located, and combine the brightness of the environment with the user-preset or factory-default reading demand brightness to intelligently set the first brightness. Or the wearable terminal can also intelligently set the first brightness in combination with the content displayed on the display screen and the brightness required for reading set by the user or the factory default. For example, the brightness of the user reading the SMS and watching the video may be inconsistent.

The viewing angle of the display screen can be adjusted by adjusting the voltage attached to the liquid crystal display screen, thereby adjusting the rotation and arrangement of the liquid crystal molecules in the display screen, thereby achieving the adjustment of the viewing angle. The first angle range may be preset by the user, or may receive multiple adjustments by the user, so that the angle range that the user is used to use is the first angle range.

Further, if the wearable device is equipped with a front camera, the front camera can be turned on to detect whether there are other people around the user, and if no other people are present, the viewing angle range or the viewing angle range may not be adjusted Larger, if there are other people, the adjustment of the viewing angle is started. The viewing angle can be set in multiple ranges. The wearable terminal makes intelligent judgments based on the number of others around the user and the distance, thereby selecting the appropriate display angle.

S103: If the wearable device is not in a horizontal placement state, determine whether the wearable device is in a vertical placement state.

In a specific implementation scenario, if it is determined that the wearable device is not in the horizontal placement state, it is determined whether the wearable device is in the vertical placement state. It is similar to the process of determining whether the wearable device is placed horizontally.

The wearable device can judge whether it is in the vertical position by the gravity sensor and / or the level. Since the wearable device is often in motion when worn on the user, a second sensing range (such as 80 ° ～ 100 °, -80 ° ～ -100 °, etc.) can be set in advance, when the gravity sensor and / or level gauge determines the current When the wearable device is within the second sensing range, it can be determined that the wearable device is in a vertically placed state.

In other implementation scenarios, the user may put the wearable device in a vertical state and input a recording instruction. The wearable device receives the recording instruction, and responds to the recording instruction to record the current state of the gravity sensor, which is a vertical state. When the wearable device detects that the state of the gravity sensor is consistent or similar to the recorded vertical state (the error is less than a preset threshold), it is determined that the wearable device is in the vertical placement state. Further, the wearable device can be placed in the vertical state multiple times, and the multiple states corresponding to the gravity sensor can be recorded separately, and the range of the vertical state can be set according to the corresponding multiple states. When the wearable device detects that the fixed gravity sensor is in When the vertical state is within the range, it is determined that the wearable device is in the vertical state.

Further, since the wearable device is worn on the user and is often in a motion state, it may be in a vertical state due to coincidence. At this time, the user does not need to view the display content of the display screen of the wearable device. In order to avoid this situation, therefore, when the wearable terminal detects that the gravity sensor is in the vertical state or the range of the vertical state, if it is detected that the gravity sensor is in the vertical state or the range of the vertical state exceeds a preset time length (for example, 1S, 2S, etc.) It is determined that the wearable device is placed vertically.

S104: If the wearable device is placed vertically, display the display screen of the wearable device vertically.

In a specific implementation scenario, if it is determined that the wearable device is in a vertically placed state, the display screen of the wearable device is displayed vertically. The vertical screen display may be a display angle preset in the wearable device, or may be a display angle adjusted by the user device according to personal usage habits.

In other implementation scenarios, similar to the state where the wearable is placed horizontally, when it is determined that the wearable terminal is protecting the user's personal privacy and can be displayed on a horizontal screen, the display brightness of the display screen is adjusted accordingly to the second brightness and / Or adjust the viewing angle of the display to the second angle range.

The second brightness may be preset by the user, or may receive multiple adjustments by the user, so as to learn the user's usage habits, so as to obtain the brightness used by the user as the second brightness. In addition, the second brightness can also obtain the brightness of the environment in which the user is currently located, and combine the brightness of the environment with the reading brightness preset by the user or the factory default, and set the second brightness intelligently. Alternatively, the wearable terminal may intelligently set the second brightness in combination with the content displayed on the display screen and the brightness required for reading set by the user or the factory default. For example, the brightness of the user reading the SMS and watching the video may be inconsistent.

The second angle range may be preset by the user, or may receive multiple adjustments by the user, so as to obtain the angle range that the user is used to use as the second angle range. Further, if the wearable device is equipped with a front camera, the front camera can be intelligently turned on to detect whether there is another person around the user. If no other person exists, the viewing angle range or the viewing angle The range is large. If there are other people, the adjustment of the viewing angle is started. The viewing angle can be set in multiple ranges, and the wearable terminal makes intelligent judgments based on the number of others around the user and the distance, so as to select an appropriate display angle.

In another implementation scenario, the wearable device is neither horizontally placed nor vertically placed, which means that the user does not need to view the display screen, and can turn off the display screen of the wearable device to save resources.

S105: Obtain display adjustment information, and adjust at least one of the display angle, display brightness, and viewing angle of the display screen according to the display adjustment information.

In a specific implementation scenario, when it has been determined that the wearable device is placed horizontally or vertically, and the horizontal or vertical display of the display screen is adjusted accordingly according to the result of the determination, the display adjustment information is acquired and the display adjustment The information includes instructions to adjust at least one of the display angle, display brightness, and viewing angle of the display screen. The wearable device adjusts at least one of display angle, display brightness, and viewing angle according to the display adjustment instruction.

In this implementation scenario, the display adjustment information is the first adjustment instruction input by the user. For details, please refer to FIG. 2. FIG. 2 is a schematic flowchart of a first embodiment for obtaining display adjustment information and adjusting display display according to the display adjustment information in the horizontal and vertical screen switching method provided by the present invention.

S201: Receive a first adjustment instruction input by a user, where the first adjustment instruction is used to instruct to adjust at least one of the display angle, display brightness, and viewing angle of the display screen.

In a specific implementation scenario, the display adjustment information is the first adjustment instruction input by the user. After the wearable device has adjusted the horizontal display or vertical display of the display screen according to whether it is in the horizontal placement state or the vertical placement state determined in step S101 to step S104, if the user is in the current display angle, display brightness and viewing angle If any of the items is not satisfactory, the first adjustment instruction is sent to the wearable terminal, so that the wearable terminal receives the first adjustment instruction, and adjusts the display angle, display brightness, and visibility of the display screen accordingly in response to the first adjustment instruction At least one of the angles.

For example, when it is determined that the wearable terminal is placed horizontally, the display frequency of the wearable terminal is displayed on the horizontal screen, but the user ’s arm is not horizontally placed on the chest at this time, the result of the horizontal screen display cannot fully satisfy the user ’s Demand, if the display screen displays text content at this time, and the font size is small, the line of sight of the user's reading and the direction of the text displayed on the display screen are not horizontal, and the user is struggling to read. At this time, the user may input a first adjustment instruction, and the first adjustment instruction includes an adjustment instruction for adjusting the display angle of the display screen. Specifically, the user can adjust the display angle of the display screen by sliding the finger on the display screen. For example, if the user slides the finger upward, the display angle of the display screen is adjusted counterclockwise, and if the user slides the finger downward, the display angle of the display screen is smooth. Hour hand adjustment. As shown in Figures 3a and 3b. FIG. 3a is a schematic diagram of an embodiment of a display state when a display screen of a wearable device receives a first adjustment instruction including adjusting the display angle of the display screen in the horizontal and vertical screen switching method provided by the present invention, and FIG. A schematic diagram of an embodiment of adjusting the display angle of the display screen of the wearable device in the screen switching method in response to the first adjustment instruction including adjusting the display angle of the display screen, wherein the word "positive" in the figure is only for convenient display of the adjustment effect.

It can be defined that the user's finger slides once, and the display screen adjusts a unit angle in the corresponding direction. The unit angle may be a user preset or a factory default, for example, 3 °, 5 °, or 10 °. You can also obtain the length of the distance that the user's finger slides on the display screen, and adjust the corresponding angle according to the length response. For example, it can be preset to slide 1cm and adjust 5 °. Correspondingly, the display angle of the display screen is adjusted counterclockwise by 5 °, and if it is detected that the user's finger slides down 2 cm on the display screen, the display angle of the display screen is adjusted clockwise by 10 °. Or, if the user presses, presses, or double-clicks the display screen, the display screen pops up a corresponding dialog box, and the user can enter the direction and angle to be adjusted in the dialog box. For another example, a physical key can be set on the wearable terminal or a virtual key can be set on the display screen of the wearable terminal, and the user can adjust the display angle of the wearable terminal by triggering the physical key or the virtual key. After receiving the first adjustment instruction including the adjustment instruction of the display angle, the corresponding angle is adjusted accordingly.

In other implementation scenarios, the first adjustment instruction of the user further includes adjustment of the display brightness and viewing angle of the display screen. The specific method of adjustment can be similar to the method of adjusting the display angle of the display screen above. Further, the fingerprints of different fingers of the user can be bound to the adjusted content, for example, the fingerprint of the right index finger adjusts the display angle, the fingerprint of the right middle finger adjusts the display brightness, and the ring finger of the right hand adjusts the viewing angle. The specific finger fingerprint and adjustment content can be set by the user.

When the user enters the first adjustment instruction, the wearable device first recognizes the fingerprint of the finger used by the user and determines the user's current adjustment object, such as recognizing the right middle finger used by the user, according to the direction of the right middle finger sliding on the display screen And the number of times or distance to adjust the display brightness. For example, when it is detected that the user's right middle finger slides upward on the display screen once, the corresponding brightness (for example, 1 lux) of the preset brightness adjustment will be displayed accordingly.

Or the user through operations like long-press, re-press or double-click the display, the display pops up a dialog box, the user can enter the object to be adjusted in the dialog box, for example, the viewing angle, and the direction and amount of adjustment , For example, by 20 °.

S202: Adjust at least one of the display angle, display brightness, and viewing angle displayed on the display screen according to the first adjustment instruction.

In a specific implementation scenario, after receiving the first adjustment instruction, the wearable device adjusts at least one of the display angle, display brightness, and viewing angle of the display screen according to the first adjustment instruction. For example, the first adjustment instruction includes adjusting the display angle counterclockwise by 5 ° and reducing the viewing angle by 20 °, then the wearable device adjusts the display angle accordingly, adjusts the display angle counterclockwise by 5 °, and adjusts the deflection angle of the LCD And / or arrangement to reduce the viewing angle by 20 °.

In other implementation scenarios, when the display brightness and viewing angle are excessively reduced or reduced, it will reduce the user's reading and writing perception. Therefore, a minimum display brightness and minimum viewing angle can be preset. When the value adjusted by the user is lower than this At the lowest display brightness and the lowest viewing angle, it is no longer adjusted according to the user's instructions, but to the lowest display brightness and the lowest viewing angle. Similarly, the highest display brightness and the highest viewing angle can also be preset. When the value adjusted by the user is higher than the highest display brightness and the highest viewing angle, it is no longer adjusted according to the user's instruction, but the high display brightness and the highest display brightness are displayed. The highest viewing angle.

In another implementation scenario, the display adjustment information is a second adjustment instruction generated by the wearable device. For details, please refer to FIG. 4. FIG. 4 is a schematic flowchart of a second embodiment for obtaining display adjustment information and adjusting display screen display according to the display adjustment information in the horizontal and vertical screen switching method provided by the present invention.

S401: Obtain a projection of the connection between the eyes of the user on the display screen, and obtain a first angle between the projection and the center line of the display screen.

In a specific implementation scenario, the display adjustment information is the first adjustment instruction input by the user. After the wearable device has adjusted the display angle of the display screen according to whether it is in the horizontal placement state or the vertical placement state determined in steps S101 to S104, in order to make the display angle fit the user's reading direction, the wearable terminal turns on the front camera, Obtain the specific position of the user's eyes, and calculate the projection of the connection between the user's eyes on the display screen. Compare the projection with the center line of the display screen to obtain the first angle between the projection and the center line of the display screen. As shown in FIG. 5a, FIG. 5a is a schematic diagram of an embodiment of a connection between the projection of the user ’s eyes on the display screen and the center line of the display screen in the horizontal and vertical screen switching method provided by the present invention, wherein the dotted line is the connection between the user ’s eyes The projection on the display screen, the solid line is the center line of the display screen, and the angle between the dashed line and the solid line is the angle A. The "positive" word in the figure is only for the convenience of showing the adjustment effect.

The center line of the display screen can be preset. For the horizontal screen display and vertical screen display of the display screen, a center line of the display screen is preset respectively. The center line of the display screen is horizontal to the display direction of the horizontal screen display or the vertical screen display. A diameter of the display.

S402: Generate a second adjustment instruction according to the first angle, where the second adjustment instruction is used to instruct the display angle of the display screen to deflect the first angle.

In a specific implementation scenario, a second adjustment instruction is generated according to the first angle, and the second adjustment instruction is used to instruct the display angle of the display screen of the wearable terminal to deflect the first angle. The second instruction includes the size of the first included angle and the direction in which the adjustment needs to be deflected. For example, as shown in FIG. 4a, the size of the first angle between the projection and the center line is angle A, and the direction of deflection is clockwise deflection.

S503: Adjust the display angle of the display screen according to the second adjustment instruction.

In a specific implementation scenario, after receiving the second adjustment instruction, the wearable device reads the size of the first included angle and the direction of adjusting the display angle deflection included in the second adjustment instruction, and according to the second adjustment instruction, Adjust the display angle accordingly to deflect the first included angle in this deflection direction.

Please refer to FIG. 5b. FIG. 5b is a schematic diagram of the display effect of an embodiment in which the display angle of the display screen of the wearable device is adjusted by the first included angle in the horizontal and vertical screen switching method provided by the present invention. As shown in FIG. 5b, when the display angle of the display screen is deflected clockwise by angle A according to the second adjustment instruction, the line connecting the eyes of the user is projected on the display screen to coincide with the center line.

In another implementation scenario, if the angle between the line projected by the user's eyes on the display and the center line is less than the preset threshold (such as 5 °, 3 °, etc.), it will not seriously affect the user's reading experience. To save resources, it is not necessary to adjust the display angle of the display screen. The second adjustment instruction may not be generated or may not respond to the second adjustment instruction after the second adjustment instruction is generated.

In yet another implementation scenario, the display angle of the display screen can only be deflected according to the unit angle, then the angle between the projection of the connection between the user's eyes on the display screen and the center line is adjusted to be less than a preset threshold ( For example, 5 °, 3 °, etc.).
