A computer return control system and method

Abstract

The invention relates to a computer return control system and method. The return control system comprises a first communication device and at least one second communication device. The first communication device comprises a first interface for receiving control information input by a user from an HID device; a second interface for transmitting interface information to the HID device; a first wireless transceiver module configured to transmit control information and receive interface information. The second communication device comprises a second wireless transceiver module, which is used for receiving control information from the first wireless transceiver module and sending interface information to the first wireless transceiver module after being paired with the first communication device; a third interface for transmitting control information to the computer; a fourth interface for receiving the currently displayed interface information from the computer. The technical proposal of the invention is implemented without installing any application software on the computer, and the plug-and-play is truly achieved. the problem that some actions cannot be simulated can be avoided; theinstantaneity of backtracking is improved considerably.

Description

technical field [0001] The invention relates to the field of information transmission, in particular to a computer back control system and method. Background technique [0002] In many application scenarios, for example, when a remote conference is held, it is often necessary for the user to control the remote computer. In the prior art, combining figure 1 The return control system of the computer shown, the external HID (Human Interface Device, user interface device) device such as mouse, display screen, touch screen is connected on a wireless transceiver box through USB, when the user inputs and controls by mouse or touch screen information, the wireless transceiver box can obtain the control information through USB, and analyze the received USB data packets to obtain the coordinates and action information of the mouse or touch screen, and then, the wireless transceiver box will analyze the The output coordinates and action information are transmitted to the remote PC (c...

AI Technical Summary

Problems solved by technology

[0004] 1. The application software must be installed on the PC, and since the OS type / version on each PC is not exactly the same, it is necessary to develop different application software for different OS types / versions;

[0005] 2. The user's control of the PC depends heavily on the functions of the application software. In this way, some actions may not be able to be simulated.

For example, the user can operate the left button, the right button and the middle scroll wheel of the mouse, but when the installed application software sets the API parameters of the OS, it only sets the parameters of the left button and the right button, and does not Do the parameter setting of the operation of the middle roller, so the user's operation of the middle roller cannot realize the action simulation;

[0006] 3. The control information needs to be processed by the wireless transceiver box and the application software on the PC, and the real-time performance of the return control is not good.
