Description

TECHNICAL FIELD

[0001] The present application relates to the field of LAN device interconnection, and particularly relates to a method and system for inputting content from a handheld terminal to a target terminal. BACKGROUND

[0002] Large-screen intelligent terminals, such as smart TVs, conference room large-screen devices, projectors, and mall advertising machines, are inconvenient for users to input text (or other content) due to their large size, lack of touch screens, or installation location.

[0003] To this end, Chinese patent CN 103607779 A discloses a multi-screen cooperative intelligent input system and an implementation method thereof. A user establishes a connection between a smart TV and a smart terminal in a LAN. When the smart TV needs to input characters, the system checks whether a smart terminal is connected to the smart TV. If not, the system pops up the default input method of the smart TV for the user to input. The smart TV completes information input and enters a normal playing program. If there is a smart terminal connected to the smart TV, the system pops up the input method of the smart TV and sends a message to the smart terminal. The smart terminal displays an input interface after receiving the message, and the user inputs information through the input method on the smart terminal. After completing information input, the smart terminal transmits and displays the input information on the smart TV, thereby completing information input of the smart TV. This solution has the following problems:

[0004] First, the handheld terminal is notified of the need to input characters when the large-screen terminal needs to input characters. After the handheld terminal completes input, the input content is sent to the large-screen terminal. Since the large-screen terminal needs to be operated first, the solution is not convenient to use.

[0005] Second, the input content is limited to text, and cannot send more content, such as text, voice, images, and videos, which has certain limitations.

[0006] Therefore, it is necessary to improve the existing method of inputting content from a large-screen intelligent terminal to simplify the input method, facilitate operation, and input various content such as images and videos. SUMMARY

[0007] To solve the above problems, the present application provides a method and system for inputting content from a handheld terminal to a target terminal to solve the problem that the user needs to manually select a terminal device to be connected from a terminal device list in the prior art, which is not convenient to use.

[0008] To this end, the method for inputting content from a handheld terminal to a target terminal provided by the present application includes the following steps:

[0009] The handheld terminal and the target terminal are connected;

[0010] The input content is entered in the input interface of the handheld terminal and sent to the target terminal. The input content includes text or files such as pictures, audio, video or documents selected from the handheld terminal. The input interface of the handheld terminal includes a text input button, a file selection button and a send button. The text input button and the file selection button are used to switch between text input and document selection functions, and the send button is used to send the input content to the target terminal.

[0011] The target terminal receives input content sent by the handheld terminal in real time, and displays the input content or automatically opens the input content by calling the corresponding application, depending on the type of input content and whether there is an active text input box on the target terminal's current interface. Specifically, this includes:

[0012] Step 131: The target terminal receives the input content sent by the handheld terminal in real time;

[0013] Step 132: Determine if the file type of the input content is text. If it is text, proceed to step 133; otherwise, proceed to step 134.

[0014] Step 133: The target terminal determines whether there is an active text input box on the current interface. If there is an active text input box, the input content is displayed in the active text input box, and the process proceeds to step 131; otherwise, the input content is discarded, and the process proceeds to step 131.

[0015] Step 134: The target terminal calls the corresponding application to open the input content based on the file type of the input content.

[0016] In the above technical method, preferably, a default application for opening document types is preset on the target terminal.

[0017] In the above technical method, preferably, the connection status with the handheld terminal is detected in real time, and the real-time receiving task is started or stopped according to the connection status.

[0018] In the above technical method, preferably, the handheld terminal is a mobile phone or a tablet computer.

[0019] The present invention also provides a system for inputting content from a handheld terminal to a target terminal, comprising a target terminal and a handheld terminal establishing a connection, and further comprising:

[0020] The input module, located on the handheld terminal, includes:

[0021] The text input button and the file selection button are used to switch between text input and document selection functions;

[0022] The send button is used to send the input content to the target terminal;

[0023] The input content includes text or files such as images, audio, video, or documents selected from the handheld terminal;

[0024] The receiving module, installed on the target terminal, is used to receive input content sent by the handheld terminal in real time;

[0025] The processing module is used to display the input content or automatically open the input content by calling the corresponding application, based on the type of input content and whether there is an active text input box on the current interface of the target terminal. Specifically, it includes:

[0026] Determine if the file type of the input content is text.

[0027] If it is text input, check if there is an active text input box on the current screen. If there is an active text input box, display the input content in the active text input box; otherwise, discard the input content.

[0028] If the input is not text, the appropriate application will be invoked to open the input content based on its file type.

[0029] In the above system, the target terminal is also equipped with a detection module, which is used to detect the connection status with the handheld terminal in real time, and start or stop the real-time receiving task according to the connection status.

[0030] As can be seen from the above technical solution, the method and system for inputting content from a handheld terminal to a target terminal provided by the present invention solves the problem that existing technologies require users to manually select the terminal device to be connected from a list of terminal devices, which is inconvenient to use. Compared with the prior art, the present invention has the following beneficial effects:

[0038] To provide a clearer explanation and description of the technical solution and implementation of the present invention, several preferred specific embodiments for implementing the technical solution of the present invention are described below.

[0039] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0040] Please see Figure 1 , Figure 1 This invention provides a flowchart of a method for inputting content from a handheld terminal to a target terminal.

[0041] like Figure 1 As shown, the present invention provides a method for inputting content from a handheld terminal to a target terminal, comprising the following steps:

[0042] Step 110: The handheld terminal establishes a connection with the target terminal.

[0043] Establishing a connection between a handheld terminal and a target terminal is an existing technology, which can be achieved in the following two ways, for example.

[0044] In the first method, the handheld terminal and the target terminal are located on the same local area network (LAN) and connect via the LAN. Specifically, the target terminal broadcasts its IP address and device information within the LAN, and the handheld terminal searches for the target terminal and initiates a connection.

[0045] This connection method is suitable for use within a company, such as in conference room large screen devices, projectors, and other target terminals. These target terminals and handheld terminals are located on the same local area network and access the local area network via wired or wireless means.

[0046] The second method involves the handheld terminal and the target terminal not being on the same local area network, but connecting via the internet. Specifically,

[0047] The target terminal (large screen device) displays a randomly generated connection code and sends its own connection code and IP information to the intermediate server.

[0048] The handheld terminal inputs the connection code displayed on the large screen to initiate a query to the intermediate server and locate the target terminal.

[0049] The intermediate server sends the target terminal's information back to the handheld terminal that requested the connection.

[0050] The handheld terminal uses the obtained IP address and port number of the target terminal to establish a connection with the target terminal.

[0051] This connection method is suitable for situations where it is inconvenient to establish a local area network, such as outdoor large-screen devices.

[0052] The handheld terminal and the target terminal can also establish a connection wirelessly via Bluetooth or other means.

[0053] Step 120: The handheld terminal opens the input interface and enters content, which is then sent to the target terminal. The input content includes text or files selected from the handheld terminal, such as images, audio, video, or documents. Documents can be Word documents, Excel documents, PPT documents, or PDF documents, etc.

[0054] The handheld terminal's input interface includes a text input button, a file selection button, and a send button. The text input button and file selection button toggle between text input and document selection. Clicking the text input button opens the handheld terminal's text input box. Clicking the file selection button opens the file explorer, allowing the user to select files such as images, audio, video, or documents from the handheld terminal. Clicking the send button sends the input content to the target terminal.

[0055] Step 130: The target terminal receives the input content sent by the handheld terminal in real time, and displays the input content or calls the corresponding application to automatically open the input content, depending on the type of input content and whether there is an active text input box on the current interface of the target terminal.

[0056] The default application to open for preset document types on the target terminal.

[0057] The specific steps of step 130 are as follows:

[0058] Step 131: The target terminal receives the input content sent by the handheld terminal in real time.

[0059] Step 132: Determine if the file type of the input content is text. If it is text, proceed to step 133; otherwise, proceed to step 134.

[0060] Step 133: The target terminal determines whether there is an active text input box on the current interface. If there is an active text input box, the input content is displayed in the text input box, and the process proceeds to step 131; otherwise, the input content is discarded, and the process proceeds to step 131.

[0061] Step 134: The target terminal opens the input content using the appropriate application based on the file type. For example, if the input content is an image, an image viewer is invoked to open the image. If the input content is a video, a video player is invoked to open the video. If the input content is a document, a document processing application is invoked to open the document, such as Office, WPS, or other document processing applications that open Word, Excel, or PowerPoint documents.

[0062] Existing large-screen input solutions are triggered from the large screen itself, such as opening an application, activating a text input box, and then launching an input window on the handheld terminal via a message to input text. However, operations on the large screen typically require a remote control, which is inconvenient and inefficient.

[0063] This invention fundamentally changes the existing large-screen input method, eliminating the need for any operation on the large screen. Input is directly performed on the handheld terminal and sent to the large screen. The large screen detects in real time whether it has received the input content from the handheld terminal. Once the input content is received, it is automatically processed according to the file type of the input content, greatly improving ease of use.

[0064] In addition, the entire input process has been greatly simplified, eliminating the need for operations such as opening an application on the large screen, activating the input box, and sending messages to the handheld terminal, thus improving input efficiency.

[0065] In this invention, to conserve system resources, the target terminal receives input from the handheld terminal in real time after connecting to it. When the target terminal disconnects from the handheld terminal, the real-time receiving function exits. That is, the target terminal continuously monitors its connection status with the handheld terminal and starts or stops the real-time receiving task based on the connection status. For example, when the target terminal establishes a connection with the handheld terminal, it starts the real-time receiving task and receives input from the handheld terminal in real time. When the target terminal disconnects from the handheld terminal, it stops the real-time receiving task, releasing resources and improving operating speed.

[0066] Based on the above method, the present invention also provides a system for inputting content from a handheld terminal to a target terminal, including a target terminal and a handheld terminal establishing a connection, and further comprising:

[0067] The input module, located on the handheld terminal, is used to create an input interface on the handheld terminal and send the input content to the target terminal.

[0068] The receiving module, installed on the target terminal, is used to receive input content sent by the handheld terminal in real time;

[0069] The processing module is used to display the input content or automatically open the input content by calling the corresponding application, based on the type of input content and whether there is an active text input box on the target terminal's current interface.

[0070] The input module includes:

[0071] The text input button and the file selection button are used to switch between text input and document selection functions;

[0072] The send button is used to send the input content to the target terminal.

[0073] The target terminal is also equipped with a detection module, which is used to detect the connection status with the handheld terminal in real time, and start or stop the real-time receiving task according to the connection status.

[0074] Based on the above description of specific embodiments, the method and system for inputting content from a handheld terminal to a target terminal provided by the present invention have the following advantages compared with the prior art:

[0075] First, users can directly input content into the handheld terminal's input interface and send it to the target terminal. The target terminal receives the input content in real time and, depending on the type of input content and whether an active text input box exists on the target terminal's current screen, displays the input content or automatically opens the corresponding application to access it. This eliminates the need for initial operation on the large screen (target terminal), simplifying the process, improving submission efficiency, and enhancing ease of use.

[0076] Secondly, the input content can be text, or it can be images, audio, video, documents, etc., and it can be automatically opened by the target terminal after being received, making it more flexible and convenient to use.

[0077] Third, the target terminal monitors the connection status with the handheld terminal in real time and starts or stops the real-time receiving task based on the connection status. This saves system resources of the target terminal and improves operating speed.

[0078] Fourth, this invention expands the application of file transfer between two interconnected computers. Specifically, the two interconnected computers can each launch a file input window, which can be resized and positioned. Content is entered through the file input window on one computer and sent to the other computer. The other computer then uses the corresponding software application to automatically open the received content in its file input window. Unlike existing technologies that first receive the file and then double-click to open it, this significantly improves efficiency.

[0079] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
