Based on the above mobile terminal hardware structure and communication device structure, embodiments of the projection method of the mobile terminal of the present invention are provided.
Referring to fig. 3, the present invention provides a projection method of a mobile terminal, and in a first embodiment of the projection method of the mobile terminal, the projection method of the mobile terminal includes:
step S10, after determining that the original projection file is sent to the receiving end, sending a request instruction to the receiving end to request to start projection operation, wherein the original projection file is used as a file to be projected at the receiving end;
with the increasing popularity of mobile terminals, mobile terminals are becoming an essential part of people's work and life. One of the usage scenarios is that users in different regions need to discuss the same file, and at this time, for the convenience of the user, the time cost of the user is saved, and the file and the operation of the user on the file can be projected through the mobile terminal. The mobile terminal can be a smart phone, or a terminal with a display device, such as a tablet computer, and the file can be a document file in various formats, such as a word document, a pdf document, or a video file. Understandably, when the mobile terminal performs projection, the number of the mobile terminals is at least two, one of the mobile terminals is used as a sending end, and the other mobile terminal is used as a receiving end. The transmitting end comprises an original projection file to be projected, and the original projection file is transmitted to the receiving end to be used as a file to be projected for projection. Specifically, a direct or indirect communication connection is established between the sending end and the receiving end, and when the direct communication connection is established, direct transmission communication between the sending end and the receiving end can be performed in a WIFI or data traffic mode; when the indirect communication is connected, the indirect transmission communication between the sending end and the receiving end can be carried out through the cloud. Before the projection operation is started, an original projection file to be projected is sent to a receiving end in advance, and after the receiving end receives the original projection file, the original projection file is taken as a file to be projected to be cached, so that the file to be projected can be projected when the projection is started. And after the original projection file is monitored to be sent to the receiving end, the original projection file is determined to be sent to the receiving end, and then a request instruction is sent to the receiving end to request projection for operation.
Step S20, after receiving the determining information for determining the starting of the projection operation, receiving an operation instruction sent by a user based on the original projection file;
further, after the original projection file is sent to the receiving end in advance by the sending end, if the projection operation is not needed between the sending end and the receiving end, the sending end and the receiving end do not perform the next operation. And when the projection operation is needed, sending a request instruction for starting projection to a receiving end, returning the determining information to the request instruction by the receiving end, and using the determining information as the starting projection operation for starting the projection. When the determination information is received, projection is started, and an operation instruction sent by a user based on the original projection file is received. Specifically, the operation instruction is made for the original projection file, when the original projection file is a video file, the operation instruction may include playing, pausing, fast forwarding, or fast rewinding the video file, and when the original projection file is a document file, the operation instruction may be sliding the document, or adding annotation information to the document, and the like.
And step S30, sending the operation instruction to the receiving end so that the receiving end can display the operation instruction on the file to be projected, and the position of the operation instruction displayed on the file to be projected corresponds to the position of the operation instruction displayed on the original projection file.
Furthermore, after receiving an operation instruction sent by a user based on the original projection file, the received operation instruction is sent to the receiving end, and the receiving end displays the received operation instruction on the file to be projected. In addition, in order to realize projection, the contents of the original projection file displayed by the sending end and the file to be projected displayed by the receiving end should be consistent, and the display position of the operation instruction in the file to be projected corresponds to the display position of the operation instruction in the original projection file, so as to maintain the consistency of the projection contents of the sending end and the receiving end.
