Embodiment
Below in conjunction with accompanying drawing, several preferred embodiments of the present invention are described in detail, but the present invention is not restricted to these embodiment.The present invention contain any in marrow of the present invention and scope, make substitute, modification, equivalent method and scheme.In order to make the public that the present invention is had thoroughly and be understood, in the following preferred embodiment of the present invention, describe concrete details in detail, and do not have for a person skilled in the art the description of these details also can understand the present invention completely.In addition, for fear of essence of the present invention is caused to unnecessary obscuring, do not describe well-known method, process, flow process, element and circuit etc. in detail.
Core concept of the present invention is, space bar on computer general-purpose MultiMedia Keyboard is transformed, form left space key and right w/space key, take alphabetical YHN, left and right space bar center on keyboard as symmetrical center line, letter is carried out to symmetrical expression distribution mapping, make the initial consonant of the Chinese phonetic alphabet be distributed in left-handed operation district, simple or compound vowel of a Chinese syllable is distributed in right-hand operated district, right-hand man, simultaneously without intersecting keystroke, realizes input Chinese fast.
As shown in Figure 1, a kind of Universal shorthand keyboard provided by the invention, its surface structure is the same with general 107,104 MultiMedia Keyboards of standard substantially, comprise the matrix film circuit of inside with right w/space key contact etc., difference is also to comprise that a control chip (not shown) and unique difference are that space bar has been divided into two parts, left-half is called left space key, and right half part is called right w/space key.
The structure of symmetric distributed Universal shorthand keyboard of the present invention is, keyboard, take YHN and center, space as boundary, is divided into two keyboard region, left and right, left-handed operation left button panel, right-hand operated right button panel, both hands ten assignment closing operations, simultaneously keystroke.
As can be seen from Figure 1, left button panel comprises QWERTASDFGZXCVB letter, totally 15.Right button panel comprises YUIOPHJKLNM letter, and totally 11, if think right-hand man's division operation, right-hand man must each self energy operation QWERTASDFGZXCVB and YUIOPHJKLNM totally 26 letters.So YUIOPHJKLNM letter should be contained in left button panel, QWERTASDFGZXCVB letter should be contained in right button panel.
The present invention adopts symmetric distributed method, what adopt is general 107,104 MultiMedia Keyboards of standard pc, the left keyboard letter lacking in left keyboard, the left keyboard letter lacking in left keyboard, we adopt symmetrical " symmetric distributed " scheme, the letter that shines upon to explain separately " disappearance " with mirror type.
Take Y, H, tri-letter keys of N as boundary, row left and right Mirroring Mapping pressed in the letter on the keyboard of left and right.For example, the first row tee on left keyboard, R, E, W, Q Mirroring Mapping are on alphabetical Y, the U of left keyboard, I, O, P.In like manner, alphabetical Y, U in left keyboard, I, O, P Mirroring Mapping are on the tee of left keyboard, R, E, W, Q.The second row letter G, F on left keyboard, D, S, A Mirroring Mapping to alphabetical H, the J of left keyboard, K, L, "; " on; In like manner, alphabetical H, J in left keyboard, K, L, "; " Mirroring Mapping is on alphabetical G, the F of left keyboard, D, S, A.The third line letter b on left keyboard, V, C, X, Z Mirroring Mapping are in alphabetical N, the M of left keyboard, ", ", ". ", "/", and alphabetical N in left keyboard, M Mirroring Mapping are upper to letter b, the V of left keyboard, and its virtual effect as shown in Figure 2.
Pc machine MultiMedia Keyboard itself is an intelligent system of being made by single-chip microcomputer, it is by periodically scanography button of keyboard handling procedure (utilizing the hardware under software-driven to complete functions such as scanning, coding, transmission), in the time that a button is pressed, after eliminating shake, scan code is transmitted to the keyboard interface that is positioned at main frame, translator is translated as the scan code in keyboard interface the coded message of corresponding key, in the time that CPU is idle, keyboard interface circuit sends main frame to above-mentioned coded message.Pc machine MultiMedia Keyboard sends key position scan code to host keyboard interface at twice, by send and connect scan code next time, sends disconnection scan code again, thereby complete the transmission of a button data when release.The scan code of keyboard in the time transmitting (connect code, disconnect code) is temporarily stored in its impact damper, under keyboard time clock is synchronous, single-chip microcomputer in keyboard is extremely high-order by status by stored buffer scan code, outwards sends serial signal successively by signal wire.
Existing pc machine MultiMedia Keyboard in the time having multiple keys to be pressed, only have the key of last closure periodically to be sent connection scan code, and after this key is released, the connection code of other keys does not also periodically send simultaneously to main frame.Press in situation at multiple buttons so simultaneously, in keyboard buffer, how to obtain the scan code of multiple keys? in the time that multiple buttons are pressed simultaneously, in fact button operation has successively, is that multiple keys are very of short duration interval time of pressing or lifting, and we feel and operate at the same time.We can redesign a computer keyboard handling procedure to the present invention is based on this principle, improve the speed of connection code and the disconnection code of key range, and the scan code of multiple buttons is sent to keyboard buffer.If we intercept and capture the scan code in buffer zone, carry out corresponding conversion by look-up table according to the encoding scheme of symmetric distributed Universal shorthand keyboard, will obtain any result that we want.
The space bar of traditional pc machine MultiMedia Keyboard is one, symmetric distributed Universal shorthand keyboard is the same with general 107,104 MultiMedia Keyboards of standard substantially, unique difference is that space bar has been divided into two parts, and left-half is called left space key, and right half part is called right w/space key.In the present invention, while being input in Chinese due to the very important feature of input in Chinese, to there is the compounding practice of left and right space bar, when input lower gear initial consonant (initial consonant of symmetrical mapping), left hand thumb will hit left space key simultaneously, when input lower gear simple or compound vowel of a Chinese syllable (simple or compound vowel of a Chinese syllable of symmetrical mapping), hand thumb will be hit right w/space key simultaneously, so symmetric distributed Universal shorthand keyboard must can be identified left and right space bar.Traditional ps/2 computer media keyboard acquiescence the second cover scan code, the make code of space bar is: 29, short in size is: F029.For the keyboard handling procedure that guarantees symmetric distributed Universal shorthand keyboard can be identified left and right space bar, the present invention proposes a scheme, the make code of left space key is: 29, short in size is: F029, the make code of right w/space key, short in size are selected from Ps/2 keyboard second overlaps the Windows multimedia scan code of scan code.
As shown in Figure 3, the present invention can adopt single-chip microcomputer as control chip, as an interface module, symmetric distributed Universal shorthand keyboard is connected with interface module by ps/2 attachment unit interface, and interface module couples together by USB plug and pc machine host.
Shown in Fig. 4 is in symmetric distributed Universal shorthand keyboard interface microcontroller module, the schematic diagram of input, output interface, keyboard interface is keyboard interface, pc interface is the interface that outputs to pc main frame, two interfaces all can be ps/2 interface, and pc interface also can be designed to USB interface.
Shown in Fig. 5 is that keyboard is processed main program flow chart.
In interface module, solidify new keyboard handling procedure, and pointed out to realize three key problems of new keyboard handling procedure and the implementation method of quick Chinese typing:
1, new keyboard handling procedure provides scan code (make code, the short in size) embodiment of symmetric distributed Universal shorthand keyboard left and right space bar, so that can be identified left and right space bar.
2, provide multikey to input principle and method simultaneously, improved the speed of connection code and the disconnection code of keyboard scan procedure identification button, interval time when reduction multikey is pressed simultaneously between each key.In Practical Project, should, according to the different single-chip microcomputers that adopt, carry out engineering test and make design parameter should meet per minute typing to be not less than 200 Chinese character requirements.
3, provide code conversion scheme, write new interrupt routine, intercepted and captured the scan code in buffer zone, carried out corresponding conversion by look-up table according to the encoding scheme of symmetric distributed Universal shorthand keyboard, will obtain any result that we want.
For further understanding realization of the present invention and operation, below we carry out English and Chinese inputting fingering example operation.
Application examples one
Input " yt " operation
If want to operate a certain Mirroring Mapping of left keyboard (otherwise or) letter in left keyboard, input method is switched to English state, open WORD.
As shown in Figure 6A, on symmetric distributed Universal shorthand keyboard, left hand thumb is put on left space, forefinger is put on tee, hand thumb is put on right w/space, forefinger is put on alphabetical Y, two hands are clicked keyboard simultaneously, and that at this moment on screen, can see left hand input is y, and that the right hand is inputted is t.Due to program design, to click in situation right-hand man simultaneously, screen display is: " yt ".If want to see a corresponding letter, please singlehanded keystroke.
Application examples two
Input " cc " operation
As shown in Figure 6B, owing to there is no ", ", ". ", "/" initial consonant in the Chinese phonetic alphabet, thus in program design, do not do "; ", ". ", "/" keyboard Mirroring Mapping, therefore, left hand middle finger is put on C key, and hand thumb is put on right w/space, middle finger is put into, upper, beating keyboard simultaneously, screen display is: " cc ".
Application examples three
For example, input Chinese character " soon ", " easily ", " leading to " three Chinese characters should operate like this in search dog Two bors d's oeuveres scheme, and input method is switched to Chinese language state, open WORD.
The operation of " kuai " as shown in Figure 7 A, left hand thumb is put on left space key, middle finger is put on alphabetical D key, and right hand forefinger is put on Y key, and two hands while beating keyboards can be seen: fast on screen.
As shown in Figure 7 B, the operation of " yi ", left hand thumb is put on left space key, forefinger is put on tee key, and right hand middle finger is put on I key, and two hands while beating keyboards can be seen: easily on screen.
As shown in Fig. 7 C, the operation of " tong ", left index finger is put on tee key, and hand thumb is put on right w/space key, the third finger is put on L key, and two hands while beating keyboards can be seen: logical on screen.
In the above in the input process of three Chinese characters of Autotoll, what may find to show for the first time is not desired Chinese character, needs to select.The phonetically similar word of Chinese character needs to select too much, and this is the shortcoming of spelling input method.The problem that solves unisonance, what lean on now is high-speed, huge memory capacitance and the intellectual analysis of computing machine.Utilize memory, association, semantic analysis, determine the technology such as word, specialized dictionary with word, after certain hour exercise, will form the dictionary of oneself at you, input each time Chinese character, vocabulary, sentence nearly all in the first candidate position, add some skills of oneself, input Chinese character will fly up.The once input of three Chinese characters of Autotoll can obtain.
Certainly, in technical solution, the present invention is elaborated in the above, still also keyboard Designing can be become to other shape, do not add and repeat at this.
The preferred embodiment of the present invention is just for helping to set forth the present invention.Preferred embodiment does not have all details of detailed descriptionthe, and also not limiting this invention is only described embodiment.Obviously,, according to the content of this instructions, can make many modifications and variations.These embodiment are chosen and specifically described to this instructions, is in order to explain better principle of the present invention and practical application, thereby under making, technical field technician can utilize the present invention well.The present invention is only subject to the restriction of claims and four corner and equivalent.
