Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, the posture change of the touch device is mostly monitored through a gravity sensing element loaded in the touch device, when the posture change of the touch device causes the deviation angle of the gravity in the plane direction of the screen relative to the gravity in the positive direction of the screen in the plane direction of the screen to exceed 45 degrees, the screen display area is rotated by 90 degrees in the deviation direction, and when the deviation angle exceeds 135 degrees, the screen display area is rotated by 180 degrees. The rotating display area covers the whole screen of the touch device, and the display area adjustment mode ensures the utilization rate of the screen and displays more complete content for a user, but in some specific occasions, the user cannot vertically hold or horizontally hold the touch device in a standard manner or in an approximately standard manner, but the display area is still in a standard direction for the user, and at the moment, the touch device is required to be capable of finely adjusting the display area displayed on the screen.
Therefore, an embodiment of the present invention provides a method for adjusting a display area, which is applied to a touch device, as shown in fig. 1, and includes the following steps:
step S101, receiving an offset angle detected by an induction element in a touch device;
step S102, determining a rotation angle of a display area of the touch device according to the offset angle; the rotation angle is the same as the offset angle;
and step 103, displaying the display area rotated according to the rotation angle on the screen of the touch device.
Specifically, the touch device includes a smart phone, a tablet computer, and other devices which are equipped with a touch screen and can be controlled in a touch manner.
The sensing element may be a gravity sensing element such as a gyroscope, a touch sensing element such as a touch panel, or another sensing element that can measure an offset angle and is mounted in a touch device. The gravity sensing element is usually presented in the form of a multi-axis sensor, which usually determines the offset angle by detecting the change of the included angle between the central axis of the mobile phone and the gravity direction. The touch sensing element firstly collects a track formed by a user through sliding operation of a touch screen, and then calculates a connecting line between a starting point and a preset point of the track and an included angle between a connecting line between a terminating point and the preset point as an offset angle.
The display area refers to an image interface for displaying content to a user on a screen of a touch device, and in the prior art, the display area usually fills the whole screen, whereas in the present application, an image displayed on the screen of the touch device after the display area is rotated may occupy only a partial area of the screen.
The screen refers to a display screen on a touch device, and the screen may be a touch screen, and is used for image presentation.
As shown in fig. 2, fig. 2(a) shows a screen of the touch device and a display area displayed on the screen, and fig. 2(b) shows that when the touch device in fig. 2(a) is tilted to the right, the display area is rotated and displayed on the screen of the touch device, and the content in the visible display area rotates along with the display area.
In step S101, when the user tilts the touch device, the processor of the touch device receives an offset angle calculated from data detected by a gravity sensing element or a touch screen in the touch device.
Step S102 determines the same rotation angle for the display area as the offset angle in step S101.
In step S103, after the touch device rotates the display area by the rotation angle, the rotated display area is displayed on the screen of the touch device, the above process is performed at a high frequency in the process of tilting the touch device by the user, and the direct visual experience given to the user is that the display area rotates in real time along with the tilting of the touch device.
Since the rotation angle of the display area of the touch device is the same as the offset angle, the rotation angle is not limited to 90 ° and 180 °, but is a more precise angle that is the same as the offset angle, and thus the display area can be rotated by any angle. For example, the offset angle received by the touch device is 30 ° clockwise, and then the rotation angle of the display area of the touch device is also 30 ° clockwise, so that the touch device rotates the display area 30 ° clockwise and then displays the display area on the screen of the touch device.
In some cases, to avoid rotating the display area too frequently, a lock button may be provided, which, when activated by the user (e.g., triggered by a click, etc.), does not rotate the display area as the detected offset angle changes.
According to the technical scheme, the offset angle detected by the sensing element in the touch device is received, then the display area of the touch device is determined according to the offset angle, the rotating angle with the same offset angle is determined, and finally the display area rotated according to the rotating angle is displayed on the screen of the touch device, so that the adjustment flexibility of the touch device on the display area of the screen is improved, and the operation obstacle in a specific use scene is avoided.
In an alternative embodiment, the step S103, as shown in fig. 3, includes the following steps:
step S1031, determining a display mode of the display area according to the operation type of the current application program; the operation types comprise a high-frequency operation type and a low-frequency operation type;
step S1032 is to present the display area rotated according to the rotation angle on the screen of the touch device in the determined display manner.
The current application refers to an application (more precisely, an application that is displaying a picture on a screen) that is running when the touch device receives the offset angle detected by the sensing element in the touch device. The operation type is that the frequency and point location distribution condition of the click operation required by the application program in use are calculated according to the historical use data of the application program, and the application program is divided into a high-frequency operation type and a low-frequency operation type.
The display mode refers to a method of adjusting and displaying a preset display area for different operation types, and may involve a rotation adjustment method for the display area and a zoom adjustment method for the display area, and a coordination method between the adjustment methods. The display mode may be a main purpose of completely displaying the display area on the screen of the touch device, or may be a main purpose of keeping the image scale in the display area as small as possible.
Specifically, the application programs of the high-frequency operation type include application programs such as a chat application program and a game application program, which require high-frequency operation on the display area, and the distribution area of the points requiring high-frequency point contact includes an area near the edge of the display area.
The application programs of the low-frequency operation type include application programs such as a call application program, a video application program, a news application program, a reading application program and the like, and the application programs can meet the requirement only by seeing most of the area near the center of the display area.
By the method, the adaptability of rotation of the display area can be improved, so that the use convenience of the touch device is improved.
In an optional embodiment, in the step S1031, when the operation type of the current application program is a high-frequency operation type, the determined display manner is that the display area is completely presented on the screen of the touch device;
when the operation type of the current application program is a low-frequency operation type, the determined display mode is that a display area part is presented on the screen of the touch device.
Specifically, for an application program of a high-frequency operation type, high-frequency operation needs to ensure that each key of the application program can be normally clicked, and if some keys cannot be clicked, the function implementation of the application program is affected, so that a user needs to display a complete display area when the display area is displayed on a screen of a touch device after rotating. Therefore, the display mode corresponding to the high-frequency operation type is mainly aimed at completely displaying the display area on the screen of the touch device.
The display area is completely presented on the screen of the touch device, that is, the image of the display area is completely displayed on the screen of the touch device, and there is no lost area, that is, after the display area is rotated, the display area needs to be completely presented on the screen of the touch device by zooming.
For the application program of the low-frequency operation type, the low-frequency operation needs to ensure that the content of the application program can be clearly displayed, if the display area is greatly zoomed, the reading of the content by the user is affected, so that the user needs to keep the current image proportion as much as possible without affecting the browsing of the main content of the display area after the rotation. Therefore, the display mode corresponding to the low frequency operation type is to keep the image scale in the display area as small as possible as a main purpose. That is, after the display area is rotated, the ratio is kept unchanged, a part of the display area can be lost, and only the main part of the display area is presented on the screen of the touch device.
In an optional embodiment, when the operation type of the current application program is a low-frequency operation type, the determining that the display mode is a display area partially presented on the screen of the touch device includes:
step 201, judging whether the loss proportion of the display area after the display area is rotated according to the rotation angle exceeds a preset threshold value; the loss ratio is a ratio of an area of a part of the rotated display area which cannot be displayed on the screen of the touch device to a total area of the display area;
step 201a, if the loss ratio does not exceed a preset threshold, displaying a display area rotated according to the rotation angle on a screen of the touch device;
step 201b, if the loss ratio exceeds a preset threshold, displaying the display area rotated and scaled according to the rotation angle on the screen of the touch device, so that the loss ratio of the display area displayed on the screen of the touch device is lower than the preset threshold.
Specifically, even if the display mode of the application program of the low-frequency operation type is mainly aimed at keeping the image scale in the display area as constant as possible, when the loss scale of the display area due to the rotation of the display area is too high, the viewing of the content in the display area by the user is still affected, and in order to ensure that the viewing of the content in the display area by the user can be normally performed, the display area needs to be scaled so that the loss scale of the display area after scaling is kept within a preset threshold value at which the user can normally view the content. The predetermined threshold is preferably 30%, which is not limited in this application.
In an alternative embodiment, the offset angle includes at least one of: the touch control device comprises a gravity deviation angle collected by a gravity sensor arranged in the touch control device and a touch control deviation angle calculated according to a touch control track collected by a touch screen arranged on the touch control device.
Specifically, the gravity offset angle acquired by the gravity sensor arranged in the touch device is a change angle of a component force of a gravity direction on a plane where the touch screen is located when the gesture of the touch device is changed by acquiring the gravity sensor such as a gyroscope in the touch device. For example, when the gravity sensor detects that the direction of the gravity is changed but the direction of the component vector of the gravity on the screen of the touch device is not changed, the obtained gravity offset angle is 0.
The touch offset angle calculated according to the touch trajectory acquired by the touch screen disposed on the touch device is an included angle between a connection line between a start point and a preset point of the touch trajectory acquired by the touch screen and a connection line between an end point and the preset point, and the preset point is generally a central point of the display area.
The touch trajectory may be a trajectory of any touch point when a preset number of touch points acquired by the touch screen simultaneously move in a similar trajectory, may be a trajectory generated by dragging an icon capable of performing a dragging operation displayed in the touch screen, or may be a trajectory generated by a touch operation in other preset manners, which is not limited in this application.
In an optional embodiment, when the offset angle is a touch offset angle calculated according to a touch trajectory acquired by a touch screen disposed on the touch device, step S103 includes:
1033, determining a scaling ratio for the display area according to a relative position relationship between the start point and the end point in the touch track;
and 1034, displaying the display area which is rotated according to the rotation angle and zoomed according to the zoom ratio on the screen of the touch device.
Specifically, when the offset angle is a touch offset angle calculated according to a touch trajectory acquired by a touch screen disposed on the touch device, in addition to rotating the display area, the display area may be zoomed according to the touch trajectory acquired by the touch screen disposed on the touch device.
The scaling of the display area is calculated by calculating the relative position relationship between the start point and the end point in the touch track, which may be by calculating the distance difference between the distance between the start point and the preset point and the distance between the end point and the preset point, and taking the ratio of the distance difference and the distance between the start point and the preset point as the scaling (for example, as shown in fig. 4, point a is the start point, point b is the end point, point x is the preset point, point l is the preset point1Is the distance from the starting point to a predetermined point,/2Is the distance from the termination point to the preset point); or the corresponding scaling can be matched according to the mapping relation between the length of the displacement and the preset scale by calculating the displacement from the starting point to the end point. By the method, operability of the display area can be improved, and rotation and scaling of the display area can be achieved simultaneously through one touch operation of a user.
The offset angle may include a gravity offset angle collected by a gravity sensor disposed in the touch device and a touch offset angle calculated according to a touch trajectory collected by a touch screen disposed on the touch device. Therefore, the corresponding selection priority for the offset angle needs to be set according to the specific application scenario. Three more typical application scenario implementations are illustrated below:
in an optional embodiment, when the currently displayed content of the display area is any one of a video, a picture and a call prompt animation, the offset angle is a gravity offset angle;
after the display area rotated according to the rotation angle is presented on the screen of the touch device, the method further includes:
and re-determining the rotation angle of the display area of the touch device according to the gesture information carried in the received touch control command, displaying the display area rotated according to the re-determined rotation angle on a screen of the touch device, and stopping collecting the gravity offset angle through a gravity sensor.
The gesture information is a track of any touch point when the preset number of touch points acquired by the touch screen simultaneously move along similar tracks, a track generated by dragging an icon which is displayed in the touch screen and can be dragged, or a track generated by touch operation in other preset modes, and the application is not limited thereto.
Specifically, when a user uses the touch device to watch videos or pictures or make a call (including voice call or video call), the display area is usually required to be forward to the user, so that the user can watch the videos or pictures conveniently.
When a user needs to further adjust the display area in a touch manner, for example, the user touches the touch screen with a preset gesture or drags a draggable icon displayed on the touch screen for adjustment, a sensing element in the touch device generates a touch control instruction carrying gesture information acquired by the sensing element and sends the touch control instruction to a processor of the touch device, the touch device selects a touch offset angle as an offset angle to readjust the display area, and meanwhile, the touch device controls the gravity sensor to stop acquiring the gravity offset angle, namely, the gravity sensing rotation function is turned off.
In an optional embodiment, when the currently displayed content of the current display area is the main interface, the offset angle is a touch offset angle;
after the display area rotated according to the rotation angle is displayed on the screen of the touch device, when the touch device starts an application program, the method further includes:
