Detailed Description
The invention provides a wireless communication screen projection method, a screen projection terminal and a display terminal for realizing the method, and aims to solve the technical problem that in the prior art, the operability of a user of the screen projection terminal is poor.
In order to solve the technical problems, the general idea of the embodiment of the present application is as follows: when the display terminal and the screen projection terminal are in the same communication network environment and can be in communication connection with each other, the screen projection terminal can initiate a screen projection connection request to the display terminal, receive the same screen content of a screen projection interface of the display terminal and display an interface on a screen projection of the screen projection terminal; when a task bar of the screen projection terminal monitors the clicking activity of a user on the screen projection, recording the focus position of the clicking activity and sending the focus position to the display terminal; the display terminal corresponds to a trigger focus of a main screen window interface of the display terminal according to the movable focus position on the screen, obtains a display result of the corresponding main screen window interface according to the trigger focus, updates the screen projection window interface, and projects the display result onto the screen projection of the screen projection terminal.
In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
Example 1
As shown in fig. 1, the present embodiment provides a wireless communication screen projection method, which includes the following steps:
s1) receiving a screen projection request of the screen projection terminal, and establishing screen projection communication connection between the display terminal and the screen projection terminal. The display terminal can be a computer, and the screen projection terminal can be a mobile phone. The screen projection communication connection between the display terminal and the screen projection terminal is realized through a communication application program client installed on the display terminal and the screen projection terminal; as long as the display terminal and the screen projection terminal are in the same communication network environment, communication connection can be carried out between the display terminal and the screen projection terminal.
S2) monitoring the activity on the screen of the screen projection terminal through the task bar of the screen projection terminal, and acquiring the relative position information of the activity. The relative position information of the activity may be that any corner of the screen projecting terminal is used as an origin, and the horizontal and vertical positions of the focus of the activity respectively account for the proportion of the whole length and width of the screen. For example, when the upper left corner of the screen is taken as the origin, the position of the focus clicked by the user is L away from the origin on the horizontal coordinate, H away from the origin on the vertical coordinate, and the length of the screen is L1 and the width of the screen is H1, the relative position information of the activity is (L/L1, H/H1).
It should be noted that the screen projection is a display screen of the screen projection terminal or a covering screen of the display screen of the screen projection terminal, and may also be a second display screen of the screen projection terminal.
S3) the relative position information of the activities corresponds to the trigger focus of the main screen window interface of the display terminal. In actual operation, since the interfaces of the display terminal and the screen projection terminal are consistent, when the user has a trigger action on the screen projection terminal, the trigger focus position is also consistent with the corresponding position of the display terminal, for example, as described in step S2), when the relative position information of the activity is (L/L1, H/H1), the upper left corner of the main screen window interface of the display terminal is also taken as the origin, and if the length of the main screen window interface is L2 and the width is H2, the trigger position of the main screen window interface of the display terminal corresponding to the activity is obtained as (L2L/L1, H2H/H1).
S4) obtaining a display result of the corresponding main screen window interface according to the trigger focus, and projecting the display result to the screen projection of the screen projection terminal. When the user has the trigger action on the screen projection terminal, although the user does not actually do the corresponding trigger action on the screen projection terminal, the same operation effect as that of the trigger action at the corresponding position of the display terminal is obtained; and the corresponding operation result can be seen at the screen projection terminal. The technical effect that the program operation of the display terminal can be remotely controlled through the screen projection terminal is the same as that of the display terminal, any other operation of the display terminal is not influenced, the occupation of the corresponding program operation of the screen projection terminal on the memory is reduced, and the operable range and the memory of the screen projection terminal are effectively expanded.
It should be noted that, in the foregoing embodiment, the technical solution of the present invention is applied to a display terminal and a screen projection terminal. The display terminal can be a computer or a mobile intelligent device, but the screen projection terminal can only be a mobile intelligent device initiating communication connection, such as a mobile phone. The display result transmitted between the display terminal and the screen projection terminal can be information such as pictures, audio, video, characters and the like.
As a preferred implementation manner of the foregoing embodiment, step S1) receives a screen projection request of the screen projection terminal, and establishes a screen projection communication connection between the display terminal and the screen projection terminal, which specifically includes:
s11) creating a screen projection window interface at the display terminal, wherein the screen projection window interface is independent of the main screen window interface of the display terminal and is consistent with the main screen window interface content of the display terminal. In actual operation, because the screen projecting window and the main screen window of the display terminal are independent of each other, the screen projecting window is operated as a subprocess program of the display terminal, so that the screen projecting window does not occupy the main screen window and does not influence other operations of the main screen window of the display terminal.
S12) projecting the screen projection window interface onto the screen projection of the screen projection terminal. Particularly, the transmission of the display interface between the display terminal and the screen projection terminal is carried out through picture information, namely, the transmission is carried out in a picture mode, and information data processing in other modes is not needed, so that the operation efficiency of the display terminal is improved.
As a preferred implementation manner of the foregoing embodiment, step S2) monitors, through a taskbar of the screen projection terminal, an activity on a screen projection of the screen projection terminal, and obtains relative position information of the activity, which specifically includes:
s21) when the taskbar of the screen projection terminal monitors that a new activity exists on the screen projection corresponding to the screen projection terminal, sending the relative position information of the activity focus of the screen projection trigger information to the display terminal;
s22) receiving the relative position information of the active focus of the screen shot trigger information.
It should be noted that, because the display interface transmission between the display terminal and the screen projection terminal is transmitted through the picture information, that is, the display interface transmission is projected in a picture form, the display terminal recognizes the user instruction and obtains the user instruction by receiving the relative position information of the trigger instruction of the user at the screen projection terminal. Therefore, the screen projection terminal does not need to actually execute the instruction operation, and the display terminal completes the corresponding work. Therefore, the program running expense caused by the instruction operation of the screen projection terminal is saved, the client side of the display terminal does not need to monitor the click operation of the screen projection window from the user, and the extra running expense increased by actually receiving the instruction operation of the interaction between the user and the screen projection window is avoided, so that the running of other programs is not influenced, and particularly the interaction behavior between the other programs and the user is not influenced.
As a preferred implementation manner of the foregoing embodiment, step S3) corresponds the information of the relative position of the activity to the trigger focus of the home screen window interface of the display terminal, which specifically includes:
s31) corresponding the relative position information of the activity to the activity position of the main screen window interface of the display terminal;
s32) if the active position corresponds to the trigger focus of the main screen window interface of the display terminal, continuing to execute the step S4); otherwise, the relative position information of the activity is abandoned, and the previous step S2 is returned to).
It should be particularly noted that the taskbar of the screen projection terminal monitors new activities on the screen projection corresponding to the screen projection terminal, and the new activities are not necessarily all click actions; only when the action is a click action, namely the action is triggered, acquiring the relative position information of the action, and correspondingly displaying the corresponding position of the main screen window interface of the terminal; and if the position corresponds to the triggerable activity of the main screen window of the display terminal, the display terminal executes the triggering operation, otherwise, the action is abandoned, and the new activity on the screen of the screen projection terminal is monitored continuously through the task bar of the screen projection terminal.
As another preferred implementation manner of the foregoing embodiment, step S4) obtains a display result of a corresponding home screen window interface according to the trigger focus, and projects the display result onto a screen of the screen projection terminal, which specifically includes:
s41) starting a task bar of the display terminal to trigger a trigger focus event of the main screen window interface, and obtaining a display interface of the trigger focus event on the main screen window interface;
s42) updating the screen projection window interface as the display interface of the trigger focus event on the main screen window interface;
s43) projecting the updated screen projection window interface onto the screen projection of the screen projection terminal.
Of course, as another preferred implementation manner of the foregoing embodiment, step S4) obtains a display result of the corresponding home screen window interface according to the trigger focus, and projects the display result onto the screen of the screen projection terminal, further including:
s4-1) starting a task bar of the display terminal to trigger a trigger focus event of the main screen window interface, and obtaining a display result of the trigger focus event on the main screen window interface;
s4-2) if the display result is a window interface, updating a screen projection window interface to be the display interface of the trigger focus event on a main screen window interface, projecting the updated screen projection window interface onto the screen projection of the screen projection terminal, and returning to the step S2);
s4-3) if the display result is the target file, sending the target file to the screen projection terminal, and ending the calling.
In the specific implementation process, if the display result transmitted between the display terminal and the screen projection terminal is a target file (including but not limited to pictures, audio, video, characters and the like), the target file is transmitted to the screen projection terminal, and a user can view the target file at the screen projection terminal; and if the display result transmitted between the display terminal and the screen projection terminal is an interactive interface, continuing to monitor the activity of the user on the screen projection of the screen projection terminal through a task bar of the screen projection terminal, and acquiring the relative position information of the activity.
According to the embodiment, the display terminal executes the corresponding internal instruction operation through the external instruction transmission of the user on the screen of the screen projection terminal, and transmits the execution result interface to the screen projection terminal, so that the technical effect of directly operating the display terminal can be achieved through the interaction with the screen projection terminal without directly carrying out actual interaction with the remote display terminal by the user.
It is specifically noted that the above-mentioned method steps are not necessarily performed in the order of numbering, and thus numbering is merely for convenience of description, and any changes in steps which are necessary to achieve the objectives of the present invention are intended to be within the scope of the claims.
