Description
Technical Field
The invention relates to the technical field of remote, in particular to a method and a system for remotely inputting characters.
Background
The Remote Desktop (Remote Desktop) is used for pulling the Desktop of a host (Server) to a Remote place, displaying the Desktop on the screen of a Client (Client), and operating the Server by using the Client to achieve the effect and user experience same as the local use of the Server.
The realization method of the remote desktop generally comprises the steps of performing screen capture at a Server, performing appropriate processing, such as cutting and compression, on an obtained picture, transmitting the picture to a Client by using a network, decompressing and splicing the picture at the Client, and the like so as to restore the whole desktop. Thus, a user sitting in front of the Client can directly operate and use the remote Server machine, and feel as if sitting in front of the Server machine.
A variation of the remote Desktop is called Visual Desktop, which is a virtual Desktop. The biggest difference between the Visual Desktop and the Remote Desktop is that the Desktop displayed by the Visual Desktop is not a real Desktop but a virtual Desktop generated by a program, and the Desktop is probably spliced by partial applications of several servers; but the client is unaware of this and it is only displayed as a real desktop; many companies today have their own remote desktop technology, and what we know is RDP, SPICE, VNC. These techniques are all very different and can be finally summarized in the above implementation methods.
At present, the working schematic of character input in a Personal Computer (PC) refers to fig. 1, the PC intercepts a keyboard message input by a user, and sends the message to a local input method, and the local input method converts the keyboard message into character coding information and sends the character coding information to an application program; thus, the application can display the Chinese characters.
In a remote desktop environment, such as a PC to PC remote desktop input, the working schematic thereof is with reference to FIG. 2; the implementation of inputting text to a remote Server is generally as follows:
client (PC1) intercepts own keyboard message and sends the message to Server (PC 2);
the Server receives the keyboard message and processes it according to the local (local refers to the Server end) keyboard message;
the local keyboard message is actually sent to a local input method, and the local input method converts the keyboard message into character coding information;
the local input method sends the character coding information to the application program; thus, the application can display the Chinese characters.
This process differs from the native keypad entry only in that the keypad message is from the network and is sent from the Client.
The process has the further characteristic that the input actually uses the local input method of the Server terminal, not the input method of the Client terminal, but the input process has no relationship with the input method of the Client terminal.
In a PC-to-PC remote desktop environment, input is not a big problem because the Client also has a full keyboard. However, in recent years, with the appearance and popularization of various terminals, especially many non-PC terminals, such as smart phones, tablets and other devices, remote desktop clients have also spread to these terminals; however, the remote desktops on these terminals are not so easy to implement for input; many mobile phones and tablets have no keyboard or have no complete keyboard, on the contrary, many smart phones, tablets and other devices are equipped with quite good touch screens, and very convenient input methods such as full-screen handwriting input methods are installed; the working schematic of the current remote desktop input method from the touch screen device to the PC is shown in FIG. 3; remote input is typically implemented as follows:
calling an input method at a touch screen device (client) and switching to English input;
using a touch screen, and dotting English letters on the screen;
the input method of the touch screen equipment can convert the English letters into keyboard messages;
the RDP client intercepts the keyboard messages and sends the keyboard messages to a PC (server);
the PC receives the message and processes the message according to the local (local Server end) keyboard message;
the local keyboard message is actually sent to a local input method, and the local input method converts the keyboard message into character coding information;
the local input method sends the character coding information to the application program; thus, the application can display the Chinese characters.
The method is characterized in that the local input method of the Server terminal is actually used, but not the input method of the Client terminal; only the input process has a little relationship with the input method of the Client terminal, if the terminal does not have the English input methods, the keyboard cannot be simulated completely;
the method only uses the simplest function of the client input method, and uses the English input method to simulate a keyboard; however, in the terminal, there are many well-used input methods, such as a well-used touch screen full-screen handwriting input method, a well-used pinyin input method, and the like, which can input chinese characters, english, and the like, but are not fully utilized.
