Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In recent years, due to rapid development of mobile terminal technology, functions of mobile terminals are becoming more and more abundant. Due to the limited size of the mobile terminal, when a user browses a webpage or video through the mobile terminal, the user cannot clearly see the content on the display screen, and the watching experience of the user is reduced. Therefore, the wireless screen-throwing technology has been developed, and the wireless screen-throwing technology is to display the picture of the mobile device A (such as a mobile phone, a tablet, a notebook, a computer) on the screen B (a tablet, a notebook, a computer, a television, an all-in-one machine, a projector) of another device in real time through a certain technical method, and the output content comprises various media information and real-time operation pictures, so that the display interface is enlarged, and the watching requirement of a user is met.
According to research, at present, in the process of projecting a display interface of a mobile terminal to screen projecting equipment through a wireless screen projecting technology, a tester cannot control the screen projecting equipment through the mobile terminal, so that content related to user privacy on the mobile terminal is displayed on the screen projecting equipment, leakage of the user privacy is caused, and use experience of a user is reduced.
In order to solve the problems in the prior art, the present embodiment provides a method for controlling a screen display screen, by which, when the display content of a mobile terminal is projected to a screen projection device by a wireless screen projection technology, the display on the screen projection device can be controlled by the operation of the mobile terminal, which is convenient for a user to control the screen projection on one hand, and is beneficial to protecting privacy of the user in the screen projection process on the other hand, so as to reduce the probability of leakage of privacy of the user.
For example, when the user plays the screen on the mobile phone to the projector, the user receives the private information sent by the social software on the mobile phone, and the user can control the information to be processed on the mobile phone without the screen on the projector for displaying. Therefore, when the screen is displayed, the display screen can be controlled through the mobile terminal, and privacy disclosure of a user can be effectively avoided.
Exemplary method
The control method of the screen-throwing display picture in the embodiment can be applied to mobile terminal equipment, such as mobile phones, tablets and the like. The mobile terminal equipment has the functions of wireless screen projection and display, for example, an interface displayed on a mobile phone can be projected on a projection device for display. In specific implementation, as illustrated in fig. 1, the method for controlling the screen-projection display screen in this embodiment includes the following steps:
step S100, acquiring touch operation and determining a touch position corresponding to the touch operation.
In a specific implementation, since the mobile terminal is controlled to control the screen-throwing device, the touch operation performed by the user on the mobile terminal needs to be acquired first, and after the touch operation is acquired, the touch position corresponding to the touch operation can be determined in the embodiment. For example, the user performs a click operation on the upper left corner of the mobile phone, and it can be determined that the position corresponding to the click operation sent by the user is the upper left corner of the mobile phone. The embodiment is convenient for determining the position corresponding to the touch position on the screen throwing device in the subsequent step by acquiring the touch operation and the touch position corresponding to the touch operation, so as to control the display on the screen throwing device.
In one implementation, as shown in fig. 2, the step S100 specifically includes:
step S101, acquiring touch operation on a preset touch area;
step S102, determining a touch position corresponding to the touch operation on the touch area.
In particular, in order to obtain a touch operation more accurately, the embodiment may perform the touch operation in a touch area preset on the mobile terminal, so as to determine a position of the touch operation in the touch area. Through presetting the touch area, on the one hand, the user of being convenient for is more accurate when carrying out touch operation, on the other hand can be more accurate confirm the touch position, improves the convenience of operation.
And step 200, determining the target position of the screen throwing equipment according to the touch control position.
In this embodiment, after the touch position is obtained, the target position corresponding to the touch position on the screen projection device may be determined according to the touch position. Because the screen throwing equipment needs to be controlled, the target position when the screen throwing equipment is controlled needs to be determined, and therefore accurate control of the screen throwing equipment is facilitated.
In one implementation, as shown in fig. 3, the step S200 specifically includes the following steps:
step S201, obtaining a time difference value of two adjacent touches on a preset suspension area;
step S202, comparing the time difference value of the two adjacent touches with a preset first threshold value and a preset second threshold value respectively to obtain a comparison result, wherein the first threshold value is larger than the second threshold value;
step 203, determining a control area corresponding to the suspension area according to the comparison result, wherein the control area comprises the touch area and a virtual key area;
step 204, determining a target position corresponding to the touch position according to a preset proportional relationship between the touch area and the display area of the screen throwing device.
In a specific implementation, in the process of the mobile terminal projecting the displayed content to the projecting device, the control of the projecting device can be realized by controlling the mobile terminal, so that the content of the two parts of projecting the displayed content and controlling the projecting device is required in the process of projecting the content. Specifically, in the screen throwing process, the display interface of the mobile terminal is divided into a main screen and a virtual second screen. For a typical display terminal, the typical screen display size is the boundary size of the UI design. For example, a screen supports a resolution of 3840×2160, so that when the software is running, the UI design is bounded by 3840×2160, and the excess is not displayed. In the present embodiment, the boundary of the UI design is set to 7680×2160 resolution, that is, the content display is expanded by two times, similar to the effect of expanding the screen with hdmi for a notebook. For the Android system, the function of supporting the second screen, such as a double-screen advertisement machine, is good. In this embodiment, the display interface of the mobile terminal is divided into a main screen and a virtual second screen, which is equivalent to dual-screen display, and in the process of screen projection, the main screen obtains full-screen UI content, and a 3840×2160 screen is obtained through screen clipping and displayed in the display area of the main screen. For example, in the process of using the mobile phone to throw a screen, the display content of the main screen seen by the user is the content of the original display interface of the mobile phone. And the virtual second screen acquires full-screen UI content, obtains 3840 x 2160 pictures through picture cutting, transmits the obtained pictures to the WIFI module in real time, transmits the pictures to the screen throwing equipment through a Miracast technology, and a user cannot view the screen throwing content on the virtual second screen, wherein the virtual second screen is in a black screen state.
In order to facilitate the operation of the control area, in this embodiment, a floating area is provided on the screen of the main screen, and the floating area may be a small floating window button that can be dragged freely, and when the user clicks the floating area, the floating area is enlarged, so as to form the control area. In order to reduce the false touch of a user on a floating area in the using process, the time difference value of two adjacent touches on the floating area is obtained, and the time difference value is compared with a preset first threshold value and a preset second threshold value to obtain a comparison result, wherein the first threshold value is larger than the second threshold value. When the comparison result is that the difference value is larger than the first threshold value or smaller than the second threshold value, no processing is performed. And when the comparison result is that the difference value is larger than the second threshold value and smaller than the first threshold value, amplifying the suspension area to obtain a control area, wherein the control area is semi-transparent and suspended on a picture of the main screen. That is, when the time difference is greater than the first threshold, the time interval between two touches is longer, and the touch may be a false touch sent by the user, so that the floating area is not enlarged. For example, the user carelessly touches the floating area for a short time in the process of using the mobile phone, and the interval between the next touch and the current touch is longer, so that the current touch is considered to be the false touch of the user, and the floating area is not amplified. When the time difference is smaller than the second threshold, the time interval between the two touches is short, and the touch may be a false touch sent by a user, so that the floating area is not amplified. For example, in the process of using the mobile phone, the user does not pay attention to pressing the palm on the screen of the mobile phone completely, so that continuous touch is caused to the floating area, and at this time, the time interval between two adjacent touches is very short, so that the floating area is not enlarged. And amplifying the suspension area to obtain a control area when the time difference value is between the first threshold value and the second threshold value.
Specifically, the modes of the presentation of the control area on the screen of the home screen include a landscape screen mode and a portrait screen mode, and the replacement of the landscape screen mode and the portrait screen mode changes according to the state of the mobile terminal. When the mobile terminal is in a horizontal state, the control area is in a horizontal screen mode, and when the mobile terminal is in a vertical state, the control area is in a vertical screen mode. The control area comprises a touch area and a virtual key area, the virtual key area is positioned below the touch area, the virtual key area comprises a plurality of virtual keys, such as a return key, a menu key and the like, and the touch area does not display a screen. In the use process, a user can reduce the control area to a suspension area by clicking a return key, so that the control area is convenient to store, and the shielding of the picture of the main screen is reduced. The touch area is divided into a plurality of areas, as shown in fig. 4, and a cross-shaped dotted line is arranged on the touch area in this embodiment, so that the touch area is uniformly divided into four areas for assisting user positioning, and the states of the dotted lines in the horizontal screen mode and the vertical screen mode are respectively shown in fig. 4. That is, when a user needs to control at a certain position of the display area of the screen projection device, the position to be controlled is estimated to be located at a certain area of the display area, and then the touch operation is performed in the target area according to the target area of the touch area corresponding to the area. For example, when a user needs to control the upper left corner of the display screen of the projector, the upper left corner of the display screen of the projector can be estimated to correspond to the upper left corner area of the touch area on the mobile phone, so that the user can perform touch operation on the upper left corner area of the touch area on the mobile phone, the user can conveniently position in the operation process, and the convenience of operation is improved.
The touch area and the display area of the screen throwing device are in an equal-proportion scaling relationship, and because the screen throwing device is controlled by operating the touch area, the operating point on the touch area is required to be corresponding to the operating point on the display screen of the screen throwing device, the touch position corresponding to the touch operation is required to be acquired first, and in order to facilitate more accurate positioning, the touch coordinate corresponding to the touch position is acquired by establishing a coordinate system, and the target coordinate corresponding to the touch coordinate on the display area of the screen throwing device is calculated according to the equal-proportion scaling coefficient between the preset touch area and the display area of the screen throwing device, so that the target position is determined according to the target coordinate.
And step 300, controlling the screen projection equipment to execute an operation instruction corresponding to the touch operation at the target position.
In this embodiment, after determining the target position corresponding to the touch position on the screen-throwing device, the target position may be controlled to execute the operation instruction corresponding to the touch operation.
In one implementation, as shown in fig. 5, the step S300 specifically includes the following steps:
step S301, determining an operation instruction corresponding to the touch operation according to a corresponding relation between the preset touch operation and the operation instruction;
step S302, analyzing the operation instruction to obtain a key event corresponding to the operation instruction;
step S303, controlling the screen throwing device to execute a key event at the target position.
In implementation, since the embodiment needs to control the screen projection device according to the touch operation on the mobile terminal, the execution of the operation instruction is required in the control process. Therefore, before the screen projection device is controlled, an operation instruction which is opposite to the touch operation needs to be determined according to the corresponding relation between the preset touch operation and the operation instruction. For example, when the touch operation sent by the user is touching the touch area, the corresponding operation instruction is clicking, and when the touch operation sent by the user is sliding in the touch area, the corresponding operation instruction is dragging. After the operation instruction is acquired, the operation instruction is analyzed in the mobile terminal to obtain a key event corresponding to the operation instruction, wherein the corresponding relation between the operation instruction and the key event is preset. For example, when the operation command is to click down, the corresponding key event is to start/pause playing, and when the operation command is to drag right, the corresponding key event is to adjust the progress bar forward. After the key event corresponding to the operation instruction is analyzed, controlling the screen throwing equipment to execute the key event at the target position. For example, when a user projects a video played on a mobile phone to a projector to display, the user clicks in a touch area on the mobile phone, the mobile phone analyzes a corresponding key event to start/pause playing, controls a target position on the projector to execute the key event of starting/pausing playing, and if the video on the current projector is in a playing state, after executing the key event, the video on the projector is in a playing pause state.
In summary, the embodiment first obtains a touch operation, determines a touch position corresponding to the touch operation, determines a target position of a screen throwing device according to the touch position, and finally controls the screen throwing device to execute an operation instruction corresponding to the touch operation at the target position. Because the touch operation corresponds to the operation instruction, after the touch operation is acquired, the touch position corresponding to the touch operation is determined, then the target position on the screen throwing device is determined according to the touch position, and finally the screen throwing device is controlled to execute the operation instruction at the target position, so that a user can throw a screen, and meanwhile, the mobile terminal is controlled to realize the display control of the screen throwing device, and privacy in the mobile terminal of the user can be protected conveniently.
