Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic flowchart of a display method according to an embodiment of the present invention, where the method is applied to a terminal, and includes:
step 11: under the condition that the terminal is in a static state, acquiring the relative direction of a user face and the terminal;
step 12: and determining a display mode according to the relative direction of the user face and the terminal, wherein the display mode comprises a horizontal screen display mode and a vertical screen display mode.
In the embodiment of the invention, under the condition that the terminal is in a static state (the signal acquired by the gravity sensor of the terminal does not change), the terminal automatically determines the display mode according to the relative direction of the face of the user and the terminal, so that the display direction of the terminal is consistent with the viewing direction of the user, the viewing of the user is facilitated, the display mode is determined according to the requirement of the user, the switching control on the display screen does not need to be clicked manually, and the user experience is improved.
The above steps will be exemplified below.
The relative direction of the user face and the terminal can be indicated by the relative relation between the user face direction and the terminal placing direction, and the display mode can be specifically determined according to the size of an included angle between the projection direction of the user face direction on the terminal display screen and the terminal placing direction. For example, when the face direction of the user is a direction perpendicular to a connecting line of two eyes of the user and pointing to the mouth (as shown in fig. 2), and the placement direction of the terminal is a direction in which one long side of the terminal runs from the top end to the bottom end (as shown in fig. 3 or fig. 4, which is an X-axis direction), if an included angle between the projection direction of the face direction of the user on the display screen of the terminal and the placement direction of the terminal is 0 ° to 40 °, the face is displayed on the vertical screen; if the included angle between the projection direction of the face direction of the user on the terminal display screen and the placement direction of the terminal is 50-130 degrees, displaying on a transverse screen and enabling the included angle between the display direction and the face direction of the user to be smaller than or equal to 40 degrees; if the included angle between the projection direction of the face direction of the user on the terminal display screen and the placing direction of the terminal is 140-180 degrees, displaying the face direction on the vertical screen in a reversed mode; if the included angle between the projection direction of the face direction of the user on the terminal display screen and the placing direction of the terminal is other than the above-mentioned angle, the current display mode is not changed, that is, the current display mode is maintained. For another example, when the face direction of the user is a direction (as shown in fig. 2) perpendicular to a connection line of two eyes of the user and pointing to the mouth, and the placement direction of the terminal is a direction (as shown in fig. 3 or fig. 4) in which one long side of the terminal runs from the top end to the bottom end, if an included angle between the projection direction of the face direction of the user on the display screen of the terminal and the placement direction of the terminal is less than or equal to 45 °, the face is displayed on the vertical screen; and if the included angle between the projection direction of the face direction of the user on the terminal display screen and the Y-axis direction (as shown in fig. 3 or fig. 4) is less than 45 degrees, displaying on the horizontal screen.
As an optional specific implementation manner, the display method further includes:
acquiring a signal acquired by a gravity sensor of the terminal under the condition that the terminal is in a non-static state;
and determining a display mode according to the signal acquired by the gravity sensor.
In the embodiment of the invention, because the method which can be used for determining the relative direction of the face of the user and the terminal consumes more power at present, if the user can move the terminal, the display mode can be determined according to the signal detected by the gravity sensor of the terminal.
In the embodiment of the present invention, before the step of obtaining the relative direction between the face of the user and the terminal, the method further includes:
determining that the terminal is in a stationary state when at least one of the following conditions exists:
detecting that an included angle between the terminal and a horizontal plane is fixed and lasts for a first preset time, wherein the included angle is smaller than a first preset threshold value;
the method comprises the steps of obtaining signals collected by at least two distance sensors distributed on a terminal, wherein the at least two distance sensors are arranged on the back and/or the side of the terminal, and the signals collected by each distance sensor indicate that the distance between the terminal and an object is smaller than a second preset threshold value and lasts for a second preset time.
Specifically, if the following three conditions exist, it is determined that the terminal is in a stationary state:
the included angle between the terminal and the horizontal plane is fixed and lasts for a first preset time, and the included angle is smaller than a first preset threshold value (including the case that the included angle is equal to 0).
And secondly, acquiring signals acquired by at least two distance sensors distributed on the back face of the terminal and/or the side face of the terminal, wherein the signals acquired by each distance sensor indicate that the terminal is close to or contacts an object and lasts for a second preset time.
Thirdly, detecting that an included angle between the terminal and the horizontal plane is fixed and lasts for a first preset time, wherein the included angle is smaller than a first preset threshold value; and acquiring signals acquired by at least two distance sensors distributed on the back face of the terminal and/or the side face of the terminal, wherein the signals acquired by each distance sensor indicate that the terminal is close to (close to) or contacts an object for a second preset time. The first preset time period may be equal to the second preset time period.
In the first case, if the terminal is held by the user, the angle between the terminal and the horizontal plane will necessarily change because the user cannot keep standing still. Therefore, the embodiment of the invention judges whether the terminal is in a static state by judging whether the included angle between the terminal and the horizontal plane is fixed. A terminal may also be considered stationary if it is placed on a stationary train. For example, in the case of fig. 5 (03 is a user) in which the terminal 01 is placed on a desktop 02, an included angle between the terminal 01 and a horizontal plane is fixed, if the desktop 02 is parallel to the horizontal plane, the included angle between the terminal 01 and the horizontal plane is 0, and if the desktop 02 and the horizontal plane have an included angle of 5 °, the included angle between the terminal 01 and the horizontal plane is also fixed to 5 °. Specifically, a gravity sensor and/or a gyroscope and the like can be used for detecting whether the included angle between the terminal and the horizontal plane is fixed or not, and a timer is used for acquiring the duration of a certain fixed included angle.
For the second case, it is necessary to dispersedly arrange the at least two distance sensors on the back and/or the side of the terminal, for example, one distance sensor is arranged on each of the four corners of the back of the terminal, or one or more distance sensors are arranged on each of the four edges of the back of the terminal, because the current terminal size is generally larger than the palm of the user, if the terminal is held by the user, the hand of the user is basically impossible to be close to all the distance sensors dispersedly arranged on the back and/or the side of the terminal. Thus, if each of the distance sensors discretely disposed on the back and/or side of the terminal collects a signal indicating that the terminal is proximate to an object, the terminal may be considered not to be held by a user but to be placed on an object. For example, in the case of fig. 5 where the terminal 01 is placed on a desktop 02, signals collected by each of the distance sensors distributed around the back of the terminal 01 or four sides of the terminal 01 will indicate that the terminal is close to an object (desktop). The distance sensor may in particular be an infrared sensor.
In other embodiments, the terminal in other cases may be determined to be in a stationary state, and the present invention is not limited thereto.
Optionally, the step of obtaining the relative direction between the face of the user and the terminal includes:
starting a front camera under the condition that the terminal is in a static state;
acquiring an image acquired by the front camera;
identifying a face in the image;
and determining the relative direction of the user face and the terminal according to the recognized face.
In the embodiment of the invention, the relative direction between the user face and the terminal can be determined according to the face recognized from the image collected by the front camera. In addition, because the display mode can be determined according to the signal detected by the gravity sensor when the terminal is in a non-static state, the embodiment of the invention can start the front camera only when the terminal is in a static state, thereby reducing the power consumption of the terminal.
In other embodiments of the present invention, other ways may be adopted to determine the relative direction of the face of the user and the terminal.
Optionally, in a case that at least two faces are recognized from the image and face directions of the at least two faces are not consistent, the step of determining a relative direction between the face of the user and the terminal according to the recognized faces includes:
determining the face with the largest occupied area in the image according to the size of the area occupied by each face in the image;
and determining the relative direction of the user face and the terminal according to the face with the largest occupied area.
In the embodiment of the invention, the face with the largest occupied area in the plurality of faces identified from the images acquired by the front camera generally belongs to the user closest to the terminal, and the user closest to the terminal generally is the master user.
An optional implementation manner of the present invention is that, when the terminal is in a static state, the display manner is determined in real time according to the relative direction between the face of the user and the terminal, and the current display manner is maintained or the display manner is switched in real time according to the determined display manner. Optionally, after the step of determining the display mode according to the relative direction between the face of the user and the terminal, the method further includes:
under the condition that the terminal is detected to be moved, acquiring a signal acquired by a gravity sensor of the terminal, and determining the display mode according to the signal acquired by the gravity sensor, namely if the terminal is detected to be moved, stopping determining the display mode according to the relative direction of the face of the user and the terminal, and resuming to determine the display mode according to the signal acquired by the gravity sensor;
or,
receiving a first input for switching a display mode, and responding to the first input, and switching the current display mode of the terminal into another display mode.
In the embodiment of the invention, the display mode is determined to be only an auxiliary function of the terminal according to the relative direction of the face of the user and the terminal, so that the viewing angle of the user can be kept consistent with the display direction of the terminal under the condition that the user is inconvenient to use a hand to switch the display mode, or the display mode is not required to be switched through a switching control. Therefore, once the user can switch the display mode manually, the initial switching mode is restored, for example, when the user rotates the terminal to change the signal collected by the gravity sensor of the terminal, the display mode is switched according to the changed signal, or when the user inputs a first input (which may be clicking a switching control) for switching the display mode, the display mode is switched in response to the first input.
Another optional implementation manner of the present invention is that, after determining that the terminal is in a stationary state, after obtaining the relative direction between the user face and the terminal for the first time and determining the display manner according to the relative direction between the user face and the terminal, instead of obtaining in real time and determining the display manner according to the relative direction between the user face and the terminal, it is determined whether the display manner needs to be switched according to the changed relative direction only when it is detected that the terminal is moved (in the moving process, an included angle between the terminal and a horizontal plane is always smaller than a preset threshold value) and the relative direction between the user face and the terminal is changed. Specifically, after the step of determining the display mode according to the relative direction between the face of the user and the terminal, the method further includes:
if the relative direction of the face of the user and the terminal is detected to be changed but the terminal is not moved, the current display mode is not changed;
if the fact that the relative direction of the face of the user and the terminal is changed and the terminal is moved on a placing face is detected, whether the display mode needs to be switched or not is determined according to the changed relative direction;
in the moving process of the terminal on the placing surface, an included angle between the terminal and the horizontal plane is smaller than a third preset threshold value, whether the terminal is moved or not can be judged specifically according to data collected by sensors such as a gyroscope and the like, and the included angle between the terminal and the horizontal plane in the moving process is obtained.
In the embodiment of the invention, after the relative direction of the face of the user and the terminal is obtained for the first time and the display mode is determined according to the relative direction of the face of the user and the terminal, the display mode is not switched in real time according to the change of the relative direction of the face of the user and the terminal, so that the error switching caused by accidental head swinging action of the user in the watching process can be prevented. If the user really needs to change the display mode, the terminal can be moved, the terminal is pushed by other parts of the body without manually clicking a switching control, and the terminal can be enabled to switch the display mode according to the relative direction of the currently acquired face of the user and the terminal.
In addition, as an optional implementation manner, after the step of determining the display manner according to the relative direction between the face of the user and the terminal, the method further includes:
under the condition that the terminal is detected to be moved and the included angle between the terminal and the horizontal plane after the terminal is moved is larger than a fourth preset threshold value, acquiring a signal collected by a gravity sensor of the terminal, and determining the display mode according to the signal collected by the gravity sensor;
or,
receiving a first input for switching a display mode, and responding to the first input, and switching the current display mode of the terminal into another display mode.
In the embodiment of the invention, the display mode is determined to be only one auxiliary function of the terminal according to the relative direction of the face of the user and the terminal, the display mode does not need to be switched by manually clicking a switching control on a display screen, and the viewing angle of the user is kept consistent with the display direction of the terminal. Therefore, once the user can switch the display mode manually, the initial switching mode is restored, for example, when the user rotates the terminal to change the signal collected by the gravity sensor of the terminal, the display mode is switched according to the changed signal, or when the user inputs a first input (which may be clicking a switching control) for switching the display mode, the display mode is switched in response to the first input.
