Description
Technical field
The present invention relates to the remote technology field, relate in particular to a kind of long-range method for inputting characters with great and system.
Background technology
Remote desktop (Remote Desktop) is to move the desktop of a main frame (Server) to long-range, on the screen of a client computer (Client), shows, utilizes Client to operate Server, reaches to follow to use the same effect and the user experience of Server in this locality.
The implementation method of remote desktop generally all is to carry out screenshotss at Server, suitably handles the picture that obtains; Such as cutting, compression; Utilize network that picture is passed to Client then, picture is carried out operations such as decompress(ion), splicing at Client, so that reduce whole desktop.Like this, the user is sitting in the Client front, just can use long-range Server machine by direct control, feels just the same as being sitting in Server machine front.
A kind of distortion of remote desktop is Visual Desktop, i.e. virtual desktop.Visual Desktop with the maximum differential of Remote Desktop is exactly; The desktop that Visual Desktop shows in client computer; Not being a real desktop, is a virtual desktop that is generated by program, and this desktop might be that the certain applications by several Server are spliced into; But client computer is not known this thing, and it just thinks that a real desktop shows; At present a lot of companies all have own remote desktop technological, and we know has RDP, SPICE, VNC.These technology are all similar, can both sum up in the point that on the above-mentioned implementation method at last.
At present, the work signal of personal computer (PC) Chinese words input is with reference to Fig. 1, and PC intercepts and captures the keyboard message of user's input, issues local input method to this message, and local input method becomes literal code information to the keyboard message conversion again, and issues application program; Application program just can show Chinese character like this.
In the remote desktop environment, when importing to the remote desktop of PC like PC, its work signal is with reference to Fig. 2; Realization to long-range Server input characters generally all is following method:
Client (PC1) intercepts and captures the keyboard message of oneself, issues Server (PC2) to this message;
Server receives this keyboard message, presses local (this locality refers to the Server end) keyboard Message Processing to it;
In fact local keyboard message issued local input method, and local input method becomes literal code information to the keyboard message conversion again;
Local input method is issued application program to literal code information; Application program just can show Chinese character like this.
This process is followed in local kbhit input and is had only a difference, is exactly that keyboard message is come automatic network, sends from Client.
This process also has characteristics, and what in fact input was used exactly is that Server holds local input method, the input method of the Client that is not to use end, and its input process, the input method with the Client end a bit concerns all do not have in fact.
In the remote desktop environment of PC, input is not a big problem, because Client also has complete keyboard at PC.But in the last few years, along with the appearance at various terminals with popularize, the terminal of a lot of non-PCs particularly, such as the appearance of equipment such as smart mobile phone, Tablet, the remote desktop client also spreads on these terminals; Yet the remote desktop on these terminals will be realized input, is not so easy just; A lot of mobile phones, Tablet do not have keyboard, perhaps do not have complete keyboard, on the contrary, equipment configurations such as a lot of smart mobile phones and Tablet the touch-screen of fairly good usefulness, input method has been installed very easily such as full frame hand-writing input method etc.; Touch panel device is illustrated with reference to Fig. 3 to the work of the remote desktop input method of PC at present; General all is the long-range input that realizes like this:
Access input method at touch panel device (client), switch to English input;
Use touch-screen, on screen, put English alphabet;
The touch panel device input method can convert these English alphabets to keyboard message;
The RDP client is intercepted and captured these keyboard message, issues PC (service end) to these message;
PC receives this message, presses local (this locality refers to the Server end) keyboard Message Processing to it;
In fact local keyboard message issued local input method, and local input method becomes literal code information to the keyboard message conversion again;
Local input method is issued application program to literal code information; Application program just can show Chinese character like this.
The characteristics of this method, what equally in fact use is the local input method of Server end, the input method of the Client that is not to use end; Its input process just has some relation with the input method of Client end, does not have these English input methods as if on this kind terminal, then fully cannot simulating keyboard;
This method has only been used the simplest function of client input method, uses English input method to come simulating keyboard; But in fact, a lot of useful input methods are arranged on this terminal, such as the full frame hand-writing input method of useful touch-screen, useful spelling input method or the like, these input methods can be imported Chinese character or English etc., but are not fully utilized.
