Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a horizontal-vertical screen switching method according to a first embodiment of the present invention.
S101: and judging whether the wearable device is in a horizontal placement state.
In one particular implementation scenario, it is determined whether the wearable device is in a horizontal position. Whether the wearable device is in a horizontal placement state can be judged through the gravity sensor and/or the level meter. Since the wearable device is worn on the user and is in motion from time to time, a first sensing range (e.g., +/-10, 170, etc.) may be preset, and when the gravity sensor and/or the level gauge determines that the wearable device is currently within the first sensing range, the wearable device may be determined to be in a horizontally disposed state.
In other implementation scenarios, the user may place the wearable device in a horizontal state and input a recording instruction, which the wearable device receives, and records the current state of the gravity sensor as a horizontal state in response to the recording instruction. When the wearable device detects that the state of the gravity sensor is consistent with or approximate to the recorded horizontal state (the error is smaller than a preset threshold), the wearable device is judged to be in the horizontal placement state. Furthermore, can place wearable equipment in the horizontality many times, note the multiple states that gravity sensor corresponds respectively, set out the scope of horizontality according to these multiple states that correspond, when wearable sets up the scope that detects that it is in this horizontality to decide wearable equipment is in the horizontal placement state.
Further, since the wearable device is worn on the user, and is in a motion state at times, and thus may be in a horizontal state by coincidence, the user does not need to view the display content of the display screen of the wearable device at that time. In order to avoid such a situation, when the wearable terminal detects that the gravity sensor is in the horizontal state or the horizontal state range, it may determine that the wearable device is in the horizontal placement state if the wearable terminal detects that the gravity sensor is in the horizontal state or the horizontal state range for more than a preset time period (e.g., 1S, 2S, etc.).
In another implementation scenario, before determining whether the wearable device is in a horizontal placement state, it is first determined whether the wearable device starts a horizontal-vertical screen switching function, and if the wearable device starts the horizontal-vertical screen switching function, it is determined whether the wearable device is in the horizontal placement state, and subsequent steps are performed. And if the wearable device does not start the horizontal and vertical screen switching function, keeping the current display state of the display screen. Specifically, the user can open the horizontal and vertical screen switching function of the wearable device through virtual or physical keys, or the user can open the horizontal and vertical screen switching function through operations of waving arms, pressing a screen and the like.
In another implementation scenario, before determining whether the wearable device is in a horizontal placement state, it is first determined whether the wearable device is in a use state. In actual use, if the wearable device is placed in a backpack or a pocket, and if the wearable device is still in a starting state, if the wearable device is detected to be in a horizontally placed or vertically placed state, the user does not need to look up the display content of the display screen, so that the horizontal and vertical screen switching method is not necessary, resource waste is caused, and the display screen of the wearable device can be turned off in order to save resources. And the horizontal and vertical screen switching method is started only when the wearable device is in a use state. For example, the pulse, the body temperature, and the like of the user may be detected by the sensor to determine whether the wearable device is in the use state. Or whether the facial image of the user is captured or not can be started through a front camera of the wearable device, and whether the wearable device is in the use state or not is judged.
S102: and if the wearable equipment is in a horizontal placement state, displaying a display screen of the wearable equipment on a horizontal screen.
In a specific implementation scenario, if the wearable device is determined to be in a horizontal placement state, the display screen of the wearable device is displayed in a horizontal screen mode. The horizontal screen display can be a preset display angle in the wearable device, or can be a display angle adjusted by the user equipment according to personal use habits.
In other implementation scenarios, in order to protect the personal privacy of the user, the display brightness of the display screen may be adjusted to a first brightness and/or the viewing angle of the display screen may be adjusted to a first angle range when the landscape screen is displayed.
The first brightness can be preset by a user, and can also be adjusted for multiple times by the user, so that the use habit of the user is learned, and the brightness used by the user is acquired as the first brightness. In addition, the first brightness can also obtain the brightness of the current environment where the user is located, and the first brightness is intelligently set by combining the brightness of the environment with the brightness of the reading requirement preset by the user or default of the factory. Or the wearable terminal can also intelligently set the first brightness by combining the content displayed by the display screen and the reading requirement brightness set by the user or default brightness of the wearable terminal leaving the factory. For example, the brightness of the user reading the text message and watching the video may not be consistent.
The adjustment of the visual angle of the display screen can be realized by adjusting the voltage attached to the liquid crystal display screen so as to adjust the turning and arrangement of liquid crystal molecules in the display screen. The first angle range may be preset by the user, or may be adjusted for multiple times by the user, so as to obtain the angle range that the user is accustomed to using as the first angle range.
Further, wearable equipment can open this leading camera if be provided with leading camera, detects whether there is other people to exist by the user, if there is not other people to exist, then can not adjust visual angle scope, perhaps visual angle's scope is great, if there is other people to exist, then starts the regulation of visual angle. Visual angle can set up a plurality of scopes, according to the user around other people how much, the distance carries out intelligent judgement by wearable terminal to select suitable demonstration angle.
S103: and if the wearable equipment is not in the horizontal placement state, judging whether the wearable equipment is in the 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. Similar to the process of determining whether the wearable device is in a horizontal position.
The wearable device can judge whether the wearable device is in a vertical placement state through the gravity sensor and/or the level meter. Since the wearable device is usually in a motion state when worn on the user, a second sensing range (e.g., 80 ° -100 °, -80 ° -100 °, etc.) may be preset, and when the gravity sensor and/or the level meter determines that the wearable device is currently in the second sensing range, the wearable device may be determined to be in a vertical placement state.
In other implementation scenarios, the user may place the wearable device in a vertical state and input a recording instruction, which is received by the wearable device, and record the current state of the gravity sensor as a vertical state in response to the recording instruction. When the wearable device detects that the state of the gravity sensor is consistent with or approximate to the recorded vertical state (the error is smaller than a preset threshold), the wearable device is determined to be in the vertical placement state. Furthermore, can place wearable equipment in the vertical state many times, note the multiple states that gravity sensor corresponds respectively, set out the scope of vertical state according to these multiple states that correspond, when wearable sets up the scope that detects that to decide that gravity sensor is in this vertical state, judge that wearable equipment is in the vertical state of placing.
Further, since the wearable device is worn on the user, and is in a motion state at times, and thus may be in a vertical state by coincidence, the user does not need to view the display content of the display screen of the wearable device. In order to avoid such a situation, when the wearable terminal detects that the gravity sensor is in the vertical state or in the vertical state range, if the gravity sensor is detected to be in the vertical state or in the vertical state range for more than a preset time length (for example, 1S, 2S, and the like), it is determined that the wearable device is in the vertical placement state.
S104: and if the wearable equipment is in a vertical placement state, displaying a display screen of the wearable equipment in a vertical screen mode.
In a specific implementation scenario, if it is determined that the wearable device is in a vertical placement state, the display screen of the wearable device is displayed in a vertical screen mode. The vertical screen display can be a preset display angle in the wearable device, or can be a display angle adjusted by the user device according to personal use habits.
In other implementation scenarios, similar to the wearable terminal being horizontally placed, when it is determined that the wearable terminal is in a state of protecting the personal privacy of the user, the display brightness of the display screen may be adjusted to a second brightness and/or the visual angle of the display screen may be adjusted to a second angle range.
The second brightness can be preset by the user, and can also be adjusted for multiple times by the user, so that the use habit of the user is learned, and the brightness used by the user is acquired as the second brightness. In addition, the second brightness can also obtain the brightness of the current environment where the user is located, and the second brightness is intelligently set by combining the brightness of the environment with the brightness of the reading requirement preset by the user or default of the factory. Or the wearable terminal can also intelligently set the second brightness by combining the content displayed by the display screen and the reading requirement brightness set by the user or default brightness of the wearable terminal leaving the factory. For example, the brightness of the user reading the text message and watching the video may not be consistent.
The second angle range may be preset by the user, or may be adjusted for multiple times by the user, so that the angle range which the user is accustomed to use is obtained as the second angle range. Further, wearable equipment can intelligently open this leading camera if be provided with leading camera, detects whether there is other people to exist at user's side, if there is not other people to exist, then can not adjust visual angle scope, perhaps visual angle's scope is great, if there is other people to exist, then starts visual angle's regulation. Visual angle can set up a plurality of scopes, according to the user around other people how much, the distance carries out intelligent judgement by wearable terminal to select suitable demonstration angle.
In another implementation scenario, the wearable device is neither in the horizontal placement state nor in the vertical placement state, which indicates that the user does not need to view the display screen, and the display screen of the wearable device may be turned off to save resources.
S105: and acquiring display adjustment information, and adjusting at least one of a display angle, display brightness and a visual angle of the display screen according to the display adjustment information.
In a specific implementation scenario, after it is determined that the wearable device is in a horizontally or vertically placed state and the horizontal screen display or the vertical screen display of the display screen is adjusted according to the determination result, display adjustment information is acquired, where the display adjustment information includes an instruction for adjusting at least one of a display angle, a display brightness, and a visual angle of the display screen. And the wearable device correspondingly adjusts at least one of a display angle, display brightness and a visual angle according to the display adjusting instruction.
In the present implementation scenario, the display adjustment information is a first adjustment instruction input by the user. Specifically, referring to fig. 2, fig. 2 is a schematic flow chart illustrating a first embodiment of obtaining display adjustment information and adjusting display of a display screen according to the display adjustment information in the horizontal and vertical screen switching method according to the present invention.
S201: receiving a first adjusting instruction input by a user, wherein the first adjusting instruction is used for indicating to adjust at least one of a display angle, a display brightness and a visual angle of the display screen.
In a specific implementation scenario, the display adjustment information is a first adjustment instruction input by the user. After the wearable device correspondingly adjusts the horizontal screen display or the vertical screen display of the display screen according to the horizontal placement state or the vertical placement state of the wearable device judged in the steps S101 to S104, if the user feels that any one of the currently displayed angle, the display brightness and the visual angle is not satisfactory enough, a first adjustment instruction is sent to the wearable terminal, so that the wearable terminal receives the first adjustment instruction and responds to the first adjustment instruction to correspondingly adjust at least one of the display angle, the display brightness and the visual angle of the display screen.
For example, when it is determined that the wearable terminal is in a horizontally placed state, the display of the wearable terminal is frequently displayed on the horizontal screen, but the arm of the user is not in a state of being horizontally placed in front of the chest at the moment, the result displayed on the horizontal screen cannot completely meet the requirement of the user, and if the display screen displays text content at the moment and the font size is small, the line of sight for reading by the user and the text arrangement direction displayed on the display screen are not in a horizontal state, so that the user is more laboursome in reading. At this time, the user may input a first adjustment instruction, which includes an adjustment instruction to adjust the display angle of the display screen. Specifically, the user may adjust the display angle of the display screen by sliding on the display screen with a finger, for example, if the user's finger slides upwards, the display angle of the display screen is adjusted counterclockwise, and if the user's finger slides downwards, the display angle of the display screen is adjusted clockwise. As shown in fig. 3a and 3 b. Fig. 3a is a schematic view of an embodiment of a display state when a display screen of a wearable device receives a first adjustment instruction including adjusting a display angle of the display screen in the method for switching between horizontal and vertical screens provided by the present invention, and fig. 3b is a schematic view of an embodiment of a display screen of a wearable device adjusting a display angle in response to the first adjustment instruction including adjusting the display angle of the display screen in the method for switching between horizontal and vertical screens provided by the present invention, wherein a "normal" word in the figure is only used for conveniently showing an adjustment effect.
It may be limited that, when the finger of the user slides once, the display screen is adjusted to a corresponding direction by a unit angle, where the unit angle may be preset by the user or default of a factory, and may be, for example, 3 °, 5 °, or 10 °. The length of the distance of the finger of the user sliding on the display screen can be acquired, the corresponding angle is adjusted according to the length response, for example, the sliding angle of 1cm can be preset to be correspondingly adjusted by 5 degrees, if the finger of the user is detected to slide upwards by 1cm on the display screen, the display angle of the display screen is correspondingly adjusted by 5 degrees anticlockwise, and if the finger of the user is detected to slide downwards by 2cm on the display screen, the display angle of the display screen is correspondingly adjusted by 10 degrees clockwise. Or the user presses, re-presses or double-clicks the display screen, the display screen corresponds to a pop-up dialog box, and the user can input the direction and the angle which need to be adjusted in the dialog box. For another example, a physical key may be provided on the wearable terminal or a virtual key may be provided on the display screen of the wearable terminal, and the user may adjust the display angle of the wearable terminal by triggering the physical key or the virtual key. And after receiving a first adjusting instruction comprising the adjusting instruction of the display angle, correspondingly adjusting the corresponding angle.
In other implementation scenarios, the first adjustment instruction of the user further includes adjustment of display brightness and a visual angle of the display screen. The specific method of adjustment may be similar to the method of adjusting the display angle of the display screen described above. Further, fingerprints of different fingers of the user can be bound with the adjusted content, for example, the fingerprint of the index finger of the right hand adjusts the display angle correspondingly, the fingerprint of the middle finger of the right hand adjusts the display brightness correspondingly, and the fingerprint of the ring finger of the right hand adjusts the visual angle correspondingly. The specific finger fingerprint and the adjustment content can be set by the user.
When a user inputs a first adjusting instruction, the wearable device firstly identifies the fingerprint of the finger used by the user, determines an object which needs to be adjusted by the user at this time, for example, identifies the middle finger of the right hand used by the user, and adjusts the display brightness according to the sliding direction, the sliding times or the sliding distance of the middle finger of the right hand on the display screen. For example, if the middle finger of the right hand of the user is detected to slide up 1 time on the display screen, the brightness is correspondingly adjusted by the preset brightness (e.g., 1 lux).
Or the user may, by an operation like long-pressing, double-pressing or double-clicking the display, pop up a dialog box in which the user may enter an object to be adjusted, e.g. the angle of view, and an amount to be adjusted, e.g. reduced by 20 deg..
S202: and adjusting at least one of a display angle, display brightness and a visual angle displayed by the display screen according to the first adjusting instruction.
In a specific implementation scenario, after receiving the first adjustment instruction, the wearable device adjusts at least one of a display angle, a display brightness, and a visual angle of the display screen according to the first adjustment instruction. For example, the first adjustment instruction includes adjusting the display angle by 5 ° counterclockwise and reducing the viewing angle by 20 °, and the wearable device correspondingly adjusts the angle of the display content, adjusts the display angle by 5 ° counterclockwise and adjusts the deflection angle and/or the arrangement of the liquid crystal, and reduces the viewing angle by 20 °.
In other implementation scenarios, when the display brightness and the viewing angle are excessively reduced or reduced, the reading impression of the user may be reduced, so that a minimum display brightness and a minimum viewing angle may be preset, and when the user adjustment value is lower than the minimum display brightness and the minimum viewing angle, the user adjustment value is not adjusted according to the user indication, but is adjusted to the minimum display brightness and the minimum viewing angle. Similarly, it is also possible to preset the highest display brightness and the highest viewing angle, and when the user-adjusted value is higher than the highest display brightness and the highest viewing angle, the user no longer adjusts the display according to the user's instruction, but displays the high display brightness and the highest viewing angle.
In another implementation scenario, the adjustment information is displayed as a second adjustment instruction generated by the wearable device. Specifically, referring to fig. 4, fig. 4 is a schematic flow chart illustrating a second embodiment of obtaining display adjustment information and adjusting display of a display screen according to the display adjustment information in the horizontal and vertical screen switching method according to the present invention.
S401: the method comprises the steps of obtaining projection of a connecting line between two eyes of a user on a display screen, and obtaining a first included angle between the projection and a center line of the display screen.
In a specific implementation scenario, the display adjustment information is a first adjustment instruction input by the user.
