Virtual keyboard input means with multiple input focuses and method thereof

A virtual keyboard input means with multiple input focuses, wherein the means includes a control module and a virtual keyboard which is a virtual keyboard unit controlled by the control module or a virtual keyboard module communicated with the control module;

• if the virtual keyboard is a virtual keyboard unit controlled by the control module,
• the control module includes:
• a plurality of standard input/output units adapted to receive mouse click message;
• a plurality of simulated input/output units adapted to receive mouse click message, the number of the standard input/output units equals to that of the simulated input/output units and the standard input/output units have a relationship of one-to-one correspondence with the simulated input/output units;
• an input focus indicator setting unit adapted to set the current input focus indicator as the focus indicator of the standard input/output unit according to the correspondence relationship between the standard input/output unit and the focus indicator when the standard input/output unit is clicked by the mouse, and to set the current input focus indicator as the focus indicator of the simulated input/output unit according to the correspondence relationship between the simulated input/output unit and the focus indicator when the simulated input/output unit is clicked by the mouse;
• a virtual keyboard unit adapted to store mapping relationship between the coordinates and the characters and confirm the corresponding character according to the position of mouse click if a user clicks the virtual keyboard with the mouse;
• in virtual keyboard input mode, if the character is a keyboard character, the corresponding simulated input/output unit will be found according to the current input focus indicator and stores the keyboard character in a storage unit corresponding to the found simulated input/output unit;
• if the character is a status character, the virtual keyboard unit will be subjected to status processing according to the status;
• if the character is a control character, the corresponding simulated input/output unit will be found according to the current input focus indicator and the simulated input/output unit will be controlled to redraw the appearance of the simulated input/output unit according to the control character;
• the step of redrawing the appearance of the simulated input/output unit includes shifting the cursor and/or deleting the content displayed in the simulated input/output unit and the content stored in a storage area;
• a displaying unit adapted to display the plurality of standard input/output units in the standard keyboard input mode, and to display the virtual keyboard and the plurality of simulated input/output units in the virtual keyboard input mode;
• the means also includes a storage module, the storage module includes:
• a plurality of storage units adapted to store characters input by the user by using the standard keyboard or the virtual keyboard, the number of the storage units are equal with that of the standard input/output units, and each of the storage units corresponds to a pair of standard input/output unit and simulated input/output unit having the correspondence relationship;
• or if the virtual keyboard is a virtual keyboard module communicated with the control module,
• the control module includes:
• a standard input/output unit adapted to receive mouse click messages and characters input by the user by using the standard keyboard;
• a simulated input/output unit adapted to receive mouse click messages and characters input by the user by using the virtual keyboard;
• an input focus indicator setting unit adapted to set the current input focus indicator as the focus indicator of the standard input/output unit when the standard input/output unit is clicked by the mouse, and to set the current input focus indicator as the focus indicator of the simulated input/output unit when the simulated input/output unit is clicked by the mouse;
• a virtual keyboard message processing unit adapted to inform the corresponding simulated input/output unit to receive the keyboard characters cached by the virtual keyboard module according to the current input focus indicator when the virtual keyboard message sent by the virtual keyboard module is received;
• a storage unit adapted to store characters input by the user by using the standard keyboard or the virtual keyboard;
• a displaying unit adapted to display standard input/output unit in the standard keyboard input mode, and to display virtual keyboard and simulated input/output unit in the virtual keyboard input mode;
• the virtual keyboard module includes:
• a mapping unit adapted to store the mapping relationship between coordinates and characters, the correspondence relationship between the simulated input/output unit and the focus indicator, the correspondence relationship between the standard input/output unit and the focus indicator, and to output the corresponding character according to the position of mouse click if any;
• a cache unit adapted to cache keyboard character if the character output by the mapping unit is a keyboard character;
• a virtual keyboard message sending unit adapted to send virtual keyboard message to the control module if the cache unit has cached a keyboard character;
• a status processing unit adapted to perform a status process to the virtual keyboard according to the corresponding status if the mapping unit output a status character.
