Abstract

The present invention relates to a method capable of making a windows operation system possess at least two keyboards which are not influenced mutually and can work independently. The present invention provides a method capable of expanding the function of an operation system based on windows. The method solves the problem that when the windows operation system is initialized in normal operation, the windows operation system can not simultaneously possess at least two keyboards which are not influenced mutually and can work independently on the same desktop (including a virtual desktop). The method has the main path for solving the problem: keyboard message sources are discriminated in order to filter, juggle and forward keyboard messages according to the discrimination of the keyboard message sources. The method makes users of the windows operation system simultaneously and respectively operate at least two ordinary programs in a mutual non-influence state by at least two keyboards. For example, words are respectively and simultaneously input in two notepad programs by two keyboards.

Description

A kind of method that makes visual window type operating system have a plurality of keyboards

Affiliated technical field

The present invention relates to the method for a kind of expansion based on the operating system of form.

Operating system based on form refers to Microsoft Windows series operating system, the serial operating system of the X Window of Apple Mac OS series operating system, the last operation of Linux, Unix etc. with form as the man-machine interaction basis, run on the Graphic Operating System on the various hardware platforms, more than abbreviate it as windows system.

Background technology

The portion of existing windows system copy, finish initialization, when normally moving, on the same desktop (comprising virtual desktop), synchronization can only have a keyboard cursor at most.

In the existing windows system, even there is more than one keyboard to be linked in the system, but has only a keyboard cursor in the windows system, the cursor direction key of the keyboard that inserts and page turning key etc. influence the board light target simultaneously in the mode of increment and move, and the character that all buttons produce all can only occur from this cursor position.If so as long as there is the keyboard that is connected to system's operate as normal more than to be operated by the user together, the character that all keyboards produce can appear in keyboard cursor place.The keyboard cursor that can not occur respective numbers according to the quantity of keyboard, the character that different keyboards produce appears at the position at corresponding cursor place respectively.

Above-mentioned two characteristics of existing windows system show: even the hardware platform of windows system operation is connected with one with upper keyboard, synchronization also can only be operated and be no more than one, obtains the program (above abbreviation ordinary procedure) of human-computer interaction device's input information by normal channel; And can not utilize different keyboards respectively, operate more than one ordinary procedure respectively at synchronization.

In Fig. 1, two physical keyboards (1) are moved or button will produce relevant signal, be sent to keyboard driver (2) through being converted into numerical information after handling, under normal conditions, keyboard driver (2) can directly be exported relevant keyboard message to common application program (3) according to the signal that transmission comes, because the keyboard message of only sending according to keyboard driver can not judge that informed source is in some concrete physical keyboards, so, under normal conditions, even system is connected with the keyboard of an above operate as normal, windows system also can only have a keyboard cursor.

Along with the widespread use of USB, same computing machine has more than one mouse, keyboard becomes very common, and the limitation that existing windows system can only be operated an ordinary procedure simultaneously embodies more highlightedly.

Summary of the invention

In order to overcome the limitation of existing windows system, the invention provides a kind of method, can expand existing windows system, make it can finish initialization, when normally moving, same desktop (comprising virtual desktop), synchronization can have the keyboard cursor that does not disturb, works alone mutually more than.

This method makes the user of windows system to operate more than one ordinary procedure without interfering with each other respectively at synchronization with more than one keyboard.For example use two keyboards input characters without interfering with each other in two notepad programs respectively.

Solution of the present invention is (being designated hereinafter simply as the muliple keyboards scheme):

1, all are connected to the hardware platform keyboard grouping that window system is moved, every group comprises a keyboard at least;

2, every group of keyboard has a keyboard cursor;

3, the cursor key of all keyboards in every group of keyboard and page turning key all can influence this group board light target and move;

4, the character that produces of all keyboards in every group of keyboard all appears at this group board light target position;

As a group or more keyboard during by button, produce signal, be converted into numerical information after treatment and be sent to keyboard driver, the original input function that the keyboard supervisory routine provides by Windows XP receives the original input message that includes keypad information, the keyboard supervisory routine is used original input function to come the display keyboard cursor according to the grouping situation of keyboard and is arrived corresponding common applications by sending simulating keyboard message, rudimentary keyboard Hook Function is not to fall by the keyboard message screening that the keyboard supervisory routine generates with all, avoids the repetition of keyboard message.

The invention has the beneficial effects as follows: the user of windows system can operate more than one ordinary procedure respectively at synchronization without interfering with each other with more than one keyboard.Thereby increased the dirigibility of user's operation.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Be that example describes all in the drawings and Examples, but the present invention is not limited in Microsoft's Window series operating system with Microsoft's Window series operating system.

Embodiment

Concrete embodiment is divided into two kinds of situations: 1, articulate the keyboard filter drive program; 2, use original input function.

Realize that by articulating the keyboard filter drive program muliple keyboards scheme (seeing above) is applicable to all windows systems, but owing to relate to the exploitation of driver, difficulty is relatively large.Though the method development difficulty that uses original input function to realize is less relatively, be only applicable to the above version of windows xp (Windows XP) of Microsoft, certain limitation is arranged.

As follows by articulating the method that the keyboard filter drive program realizes:

In Fig. 2, on driver (2), articulated filter drive program (4), and below common applications (3), articulated keyboard Hook Function (6).Because which concrete physical keyboard (1) (4) can identification signal derive from filter drive program, therefore when transmitting keypad information the number value of physical keyboard are composed to the dwExtraInfo variable (5) of keyboard message.Before any one common applications (3) receives keyboard message, keyboard Hook Function (6) will intercept these message and they will be handled, because the pre-service of filter drive program (4), keyboard Hook Function (6) only needs the dwExtraInfo variable (5) of inquiry keyboard message just can know informed source

The physical keyboard which is concrete so can come the display keyboard cursor and transmit keyboard message to corresponding common applications (3) according to muliple keyboards scheme (seeing above).

As Fig. 2, realized the separation of a plurality of physical keyboard message by having articulated filter drive program (4) on the driver (2), and below common applications (3), articulated keyboard Hook Function (6) and realized before common applications receives keyboard message, the message from different physical keyboards being handled according to muliple keyboards scheme (seeing above).

Method by using original input function to realize is as follows:

In Fig. 3, keyboard supervisory routine (8) can receive original input message (7) by original input (Raw Input) function that Windows XP provides, because original input message (7) includes the source device that comes---the information of physical keyboard (1) of message, so keyboard supervisory routine (8) can be come the display keyboard cursor and arrive corresponding common applications (3) by sending simulating keyboard message according to muliple keyboards scheme (seeing above).Meanwhile, keyboard Hook Function (6) then is not to fall by the keyboard message screening that keyboard supervisory routine (8) generates all, to avoid the repetition of keyboard message.Therefore under Window XP system, on keyboard driver (2), do not articulate filter drive program, can realize the muliple keyboards scheme yet.

As Fig. 3, use original input function to realize the separation of a plurality of physical keyboard message and handle according to muliple keyboards scheme (seeing above) by keyboard supervisory routine (8).And below common applications (3), articulated keyboard Hook Function (6) and realized filtration repetition message.
