Description

Computer keyboard input system

The present invention relates in the computing machine fragmented information projects such as sound spectrogram literary composition be imported and converted to from keyboard the data handling system of code form.

Generally, in input Chinese character process, can not break away from the notion of " sign indicating number-word " conversion all the time, the contradiction of ubiquity one " beating of learning easily is unhappy, and that beats soon finds it difficult to learn very much again " based on the encode Chinese characters for computer Chinese and western languages information input system of standard English keyboard design.For this reason, someone has designed the whole word of Chinese character based on Chinese machinery typewriter and has imported big keyboard, totally more than about 3000 keys of bond number, with the literal on the pen point Hanzi keyboard, just the Chinese character article can be optionally imported,, any coding rule need not be remembered with shirtsleeve operation method input character information, but its card is huge unusually, will find out needed Chinese character not a duck soup from thousands of Chinese characters.The disclosed touch integrated character input character disk of Chinese patent CN85204584, the design of letter disk card and input method and the disclosed keyboard of United States Patent (USP) NO.85103865 etc. during patent CN85100008 is disclosed, the mechanical contact button of limited quantity mostly is set on the card, Chinese and western languages mixes use-pattern both can't take into account whole word input of Chinese character and coding input, to solve the difficult problem that easy is beaten soon again, can not audiovisual start at the same time, more can not intuitively import geometric figure commonly used and tab to judge correcting errors of input.This situation makes vast non-computer specialty operating personnel forbidding to computing machine, and computing machine becomes a kind of " special plane " that has only professional operating personnel just can control, and has seriously hindered computing machine in China and the penetration and promotion utilization of Chinese community in the world.

The objective of the invention is numeral, initial consonant, simple or compound vowel of a Chinese syllable, syllable district, Chinese editing area, western language control zone, Chinese and western languages data field and special function keys to be set being on the thin film switch card of arranged, make a kind of touch voice prompt figure message blended weaving keyboard, and develop keyboard therewith relevant support programs, data inputting method and applied function module.

Physical construction of the present invention as shown in Figure 1.

Disk structure of the present invention as shown in Figure 2.

Card layout of the present invention as shown in Figure 3.

20 * 35 cards that are the thin film switch matrix formation touch of key-press of arranged among Fig. 2; by the contact type panel 20 that is printed with 20 * 35 characters or figure; be printed with in length and breadth last circuit and the following circuit 21 that constitutes to circuit on the mylar of electric conductivity (PET) having; the separation layer that has 20 * 35 corresponding size windows 22 that separates upper and lower circuit; be used for above each layer of protection and (20+35) substrate 23 of root flat cable extension line and thin aluminum sheet or the polyester plate 24 with certain intensity, each lamina membranacea is bonded into the integral body of a sealing by pressure-sensitive adhesive layer.The action that button produced is to impose certain pressure on a certain key position, make the contact of the upper and lower circuit that is separated by separation layer because the effect of isolation window is closed mutually, generation is electrically connected, the pulse that be assigned on the horizontal line this moment just is added on the crossing ordinate, and signal is sent into an input end of comparer; Another action that button produces is to make in length and breadth to stop counting to cycle counter, simultaneously corresponding signal is sent into the other end of comparer, the corresponding count signal of coordinate in length and breadth gating keycoder after relatively meeting, the latter is actually a ROM (read-only memory) (ROM) chip, its storage unit had finish in advance with the corresponding standard A SCII code of each key position character.The effect of gating keycoder is the original scan code output of ASCII that the keyboard coordinate position is converted to respective symbols.

Card 1 left and right sides of the tape character of contact type panel respectively has row to represent the parallel key of consonant key 25 and everyday character and the modal particle key 26 middle low-lying shapes that assume diamond in shape among Fig. 3, wherein some initial consonant is compressed merger according to exclusion principle, g, k, h and j, q, x form the assume diamond in shape parallel key of low-lying shape of band chute of three centres, represent incompatible merger key.The card 1 of tape character respectively has delegation to represent the parallel key of final key 27 and similar simple or compound vowel of a Chinese syllable syllable Chinese character key 28 middle rectangular low-lying shapes up and down, and final key has four incompatible merger keys of representing with the low-lying plane of rectangular band chute.The card 1 middle the initial and the final of tape character coordinate joint in length and breadth is the syllable Chinese character key 29 that has circular bulge, the Chinese editing area 30 that the key position is provided with in the non-syllable Chinese Character Set in the card, western language control zone 31, Chinese and western languages data field 32 contains four corners and establishes in the interior scattered key of non-syllable Chinese character position and comprise that the figure input special operating key 33 in being controlled at is rectangle plane keys.Card 1 each several part of tape character, comprise each subregion with according to similar syllable Chinese character keypad and special operating key after Chinese character syllables such as exclusion principle spellings and the reasonable merger of the regularity of distribution, all overlap the input operation efficient of being convenient to searching and raising user with different light colours.Keyboard is half low-lying formula, half bulge formula, the circle of plane formula, ellipse, rhombus, rectangle, rectangle in the middle of touching by card 1 each the key position shape that is printed on 20 * 35 characters or figure on the formula panel 20 and can being.

By the circuit block diagram of Fig. 4 as can be known, thin film switch matrix 8 is drawn by cable 34 receives the peripheral interface circuit of being controlled by singlechip CPU in the control circuit board 10, the single-chip microcomputer code is exported to draw and is received code library (ROM), draw then and receive buffer register, and under the singlechip CPU interrupt control, scan code is delivered to main frame by standard DIN interface, another road of single-chip microcomputer is exported to draw under speech processor control and is received sound bank (ROM), and then draws and receive audio output circuit, drives loudspeaker 6 sounding.

The principle of work that Fig. 5 the represents following (see figure 5) of flowchart text;

Fig. 5 .a pretreatment process.

After user's start, make system enter the Chinese accepting state of agreement, the user touches any key on the card, corresponding thin film switch all can produce an original scan code, and main frame judges, in this way syllable Chinese character key, original scan code information conforms to the agreement state, can directly carry out the scan code conversion; Do not conform to the agreement state as information, CPU resets input mode, carries out the scan code conversion again, and the principle of scan code conversion is: the syllable Chinese character information converts the scan code of double byte to, and first byte is a precedence code, and second byte is follow-up sign indicating number; After other key position input information conversion, second byte is complete 0, scan code after singlechip CPU will be changed is placed in the buffer register of sixteen bit, simultaneously send a keyboard interrupt signal, behind the response of host, by the standard English keyboard interface to main frame, it is standard DIN interface transmits scan code earlier to main frame most-significant byte (precedence code), data in the buffer register move to left 8 then, and CPU judges whether the content in the buffer register is complete 0: as for complete 0, illustrate to finish once and import; Otherwise, send keyboard interrupt signal to main frame again, repeat said process, thereby the information input of input of syllabication Chinese character and alternate manner is returned again then and is waited for user's input state.

Fig. 5 .b host keyboard input treatment scheme.

The keyboard input treatment scheme that Fig. 5 .b left-half is represented is identical with the Chinese and western languages message processing flow of general western language keyboard; Right half part has increased the distinctive Chinese character syllable input of native system and has not had sign indicating number input treatment scheme, behind the input information of key position, the host keyboard administration module is converted to internal code with pretreated scan code, if adopt the Chinese character syllable input mode, the corresponding repeated code word of system searching coding schedule (same code word) is also pointed out on screen, first word of presenting bank enters the cursor position, when being defined as needed word by user's judgement, then finish once input automatically, otherwise the user should select by screen prompt, needs again by the input that once just can finish a Chinese character at least.

Fig. 5 .c syllable Chinese character input flow process.

For the input of syllable Chinese character, one-touch, presenting bank sequence first word, be that the card word enters text cursor position, be judged as non-required Chinese character as the user, can select to replace from presenting bank, after determining input, as think the inputting related term group, by the conjunction key of Chinese editing area 30, system call conjunction function, be that the phrase of lead-in appears at the screen prompt row with confirmed Chinese character, the user selects input, the cancellation phrase prompting automatically of input back; After wanting the phrase function or entering the conjunction state, in presenting bank, do not find required phrase again, then enter and wait for input state next time.

Fig. 5 .d does not have a yard method input flow process.

The Chinese character of pronunciation is not known in input, it is convenient to adopt Chinese character not have the code inputting method input, the user only need touch the lower right corner " nothing sign indicating number " key, screen is promptly opened a window, in window, 26 characters according to the feature extraction of the Chinese character natural form of a stroke or a combination of strokes according to 26 English alphabet keys position subscripts of Chinese and western languages data field 32 layout arrangement, with the geometric position of prompting form of a stroke or a combination of strokes parts on keyboard, the user is according to " earlier upper left; the bottom right, back ", principle input Chinese character first and last two component features of " in the outer earlier back ", the same code word that meets feature is pointed out on screen on the Western letter key position in the window, the automatic cancellation of system was pointed out after the user selected required Chinese character, and return syllable Chinese character input state, wait for user's input next time.

Modification process is concentrated in Fig. 5 .e the end of writing.

In syllable Chinese character input or do not have in yard input process and wouldn't revise the unisonance wrongly written or mispronounced characters, after one section or entire article input were finished, it is first that cursor is moved to literary composition, and from first to last moving cursor is read text, finds that wrongly written character handles immediately; A: hiatus, by new word of " insertion " key insertion of Chinese editing area 30; B: wrongly written character, by " modification " key of Chinese editing area 30, the unisonance Chinese character of cursor place word appears in the screen prompt row, is the unisonance wrongly written character, and then choosing is altered, if not the unisonance wrongly written character then re-enters, finishes until full text and so on.

The method of correcting mistakes of another kind of unisonance (sign indicating number) word that can take is behind input one complete sentence or paragraph, touch of key-press inferior horn " school sentence " key of facing left, system calls repeated code word artificial intelligence process module automatically, according to sentence structure, syntax and semantics is analyzed, and realizes that automatically the repeated code word of sentence and paragraph is proofreaied and correct.

U1-U9 key in western language control zone 31 is to simplify the daily information processing operation program of office automation for the convenience of the user, and the free application function key that is provided with, as long as the user calls corresponding functional modules, can take man-machine interrogation's interactive mode that it is defined as the function that oneself needs, as the DOS file management facilities, input information is handled automatically, report printing, letter, official document, schedule, paper, report (leading), automatic typesetting special functions such as notice.

To the blank key that leaves on the keyboard, the user is behind " definition " key in the touch of key-press dish upper right corner, and system allows the user behind the phrase or symbolic information of enter key position coordinate information and desire definition, is the quick enter key of user's general information with this blank key definition.

Sound prompt function is opened and shut to card 1 upper left corner " voice " key control of tape character, when it is in open mode, CPU receives key position input information, obtain its code, if Chinese character then when the card word enters text, is controlled speech processor, read sound bank ROM content, the standard pronunciation that this word is regardless of tone is sent out by audio output circuit in the conversion back; Sibilant rale sent out without exception in non-Chinese character.The user can judge that the information input operation of oneself has or not error according to sound equipment.

This keyboard volume is little, in light weight, the reliability height, life-span is long, installation and easy to carry, its keyboard layout and shape all can change satisfying the needs of different user input information directly perceived, as are matching used keyboards such as the incorporate notebook type microcomputer of main frame-keyboard and hand held microcomputer, all kinds of special-purpose terminal, intelligent desk; Can be used to develop portable Chinese and western languages writing machine, news gathering and editing machine etc.
