Description

The invention relates to the keyboard input technology of computing machine, the particularly invention of pocket-size electronic typewriter keyboard input technology.

For with various information, convey to computing machine as people's thought and requirement, people extensively adopt keyboard as input tool.But no matter present various keyboard input technologies write in one's own hand the pattern (as Chinese) of writing literal in pattern (as English) that does not mostly break away from early stage character printer aspect design philosophy or the manufacturing technology or human, there is not fully in conjunction with the language characteristic of being imported, not make full use of the various advanced achievement that existing science and technology is provided yet, especially the powerful information processing capability that computing machine had, thereby have shortcomings such as input speed is slow, use inconvenience.

The purpose of this invention is to provide a kind of keyboard input and display technique, it can simplify the work of people in the input process greatly, makes the keyboard input speed reach synchronous with velocity of thought substantially.

The present invention be a kind of be keyboard input and the displaying scheme and the system of input block with vocabulary.As a kind of input tool,, require to show the content of being imported in order to determine input status.But relevant devices of the present invention, as the pocket-size electronic typewriter, because display technique is perfect, information storage is big, as dictionary, this also is the implication of the present invention as a kind of displaying scheme so can change a little.

Except that side routinely carried out keyboard input and the content of input shown, the present invention can simpler mode, and faster speed is imported various phonetics or non-alphabetic writing, image curve, mathematical equation and computer program.The input of non-alphabetic writing is discussed earlier.Not anti-is example with Chinese.Be keyboard input (hereinafter to be referred as the keying in) process of simplifying Chinese, the present invention adopts with the Chinese Pin Yin initial of the band four tones of standard Chinese pronunciation of input Chinese character (demonstration can be used on the form of the mark four tones of standard Chinese pronunciation on the Chinese Pin Yin initial and is called the fuzzy symbol of vocabulary).If all vocabulary with same keys state are called same keyword, so, mix the four tones of standard Chinese pronunciation in 10,000 Chinese characters again with 23 initials of the Chinese phonetic alphabet more than 400 of forming these Chinese characters and have 92 kinds of states, on average each state has a hundred or so same keyword.Because this method can produce many same keywords, thus name its say fuzzy sets input technology or abbreviation fuzzy sets method.Too much can behind the fuzzy symbol of input vocabulary, add characteristic character or characteristic symbol comes it is further limited to dwindle with the keyword number for solving with keyword.A kind of concrete grammar is that artificial limit and machine choice are combined.If the artificial limit can will be divided into 16 kinds of states with keyword, very natural a kind of division is to divide by the syntactic property of vocabulary, as is divided into noun, verb etc.Being chosen in of machine further marks off ten kinds of states on this basis, as wait according to field under the relevant article and concrete sentence content select and definite vocabulary select priority for use.At this moment, can be under the constant situation of other condition with single syllable with keyword number decreased average to.Because Chinese single-syllable speech commonly used only has one or two hundred, so the fuzzy sets input method has practicality to the input of Chinese single-syllable speech.Certainly this is to say under the prerequisite of whole sentence input.Should point out in addition: above-mentioned manually at first have the partitionability and the alternative problem of a vocabulary to the division of word and machine to the selection of word, and it is subjected to condition restriction such as language itself and used device; And to the division of vocabulary and the process of definite system of selection itself also is a good chance that reduces with the ambiguity of keyword.Secondly, to machine: also have one keep and use this to part of speech division and the problem of the information of other related properties.The key that above-mentioned execution artificial division is used is referred to as the word feature function key.For the same keyword of minority that machine choice produces, promptly the expansion content of the fuzzy symbol of vocabulary can be arranged in it and use the artificial method of determining to solve on display screen.If realize the Chinese Pin Yin initial of the input tape four tones of standard Chinese pronunciation with keystroke, the keystroke number of then above-mentioned fuzzy sets input method input Chinese single-syllable speech is two to three times.This method accounts for the Chinese vocabulary overwhelming majority's the fog-level that polysyllabic word caused to input again.If the Chinese disyllabic word of certain key entry system storage is 100,000 (comprising entry), then only can produce (23 * 4) with the first letter of pinyin of being with the four tones of standard Chinese pronunciation ², be about 8,500 kinds of states, the time with 12 of keyword average out to.Being used in combination more than ten word feature function key, can to limit with the keyword number basically be in ten, and this is to select the acceptable number with computing machine.In fact, disyllabic word is that fog-level is the highest, so all measures that reduce the vocabulary ambiguity can be object with the disyllabic word only; After machine choice, need same keyword number that manual intervention determines to account for about 5 percent of total vocabulary number.Input to trisyllable, as adopting to its preceding two syllable input Pinyin letters, the first letter of pinyin of the 3rd the syllable input tape four tones of standard Chinese pronunciation (this can tell computing machine this be a trisyllable and accelerate input speed) then bonded state can reach 50,000, and can increase to 800,000 easily.Four initials only imported in quadrisyllable just can make bonded state reach 280,000.Here all count the effect of artificial division and machine choice.Certainly, in view of in fact distributions is inhomogeneous, also to look after three in specific design with when using, quadrisyllabic fuzzy problem, (slightly) to the discussion of multibyte speech more.

In sum, as can be known: the average every word keystroke number of method input Chinese disyllabic word with the first letter of pinyin of input tape four tones of standard Chinese pronunciation is less than twice.And total Chinese character is imported average every word keystroke number and is about 15 time.Simultaneously, under may situation for same content should adopt three as far as possible, quadrisyllabic method imports to improve input speed and accuracy.This is to the division of speech and should notes when using.The fuzzy sets method is to help popularizing Beijing pronunciation to the influence that language uses, and favourablely grasps the more vocabulary and the knowledge of grammar and makes people more be ready to use the word processing computing machine with people.

For wanting to use the first letter of pinyin people of method in addition, more available in theory concrete Chinese characters replace phonetic alphabet, generally, for non-alphabetic writing, be similar to the first letter of pinyin input method can adopt with keyboard input form this vocabulary each literal phonetic notation initial character or form with the keyboard input this kind literal vocabulary the first stroke stroke or form one group of each literal of vocabulary of this kind literal with the keyboard input one in character or the similar shape character and the method for adding characteristic character or adding characteristic symbol realize in unison.Here, characteristic character or characteristic symbol be respectively from the content of the word of forming vocabulary (as the not phonogram of first word of this vocabulary or " mouth " these parts are not arranged? when input, these information can not shown) or go out to send and say from the syntactic property of this vocabulary (whether is an adjective as this vocabulary), its effect is nothing but the number that dwindles with keyword.

For the fuzzy symbol of fuzzy message-vocabulary of having imported, it need be organized into sentence with correct literal expression, this mainly realizes by machine.It is according to being: can be divided into various sentence elements as its content of a sentence (its available key entry punctuation mark is divided).Table one is a kind of concrete division, and hurdle is a sentence element numbering on it, has six kinds, and following hurdle is the illustrative contents of sentence element, often have certain sentence element to be omitted certainly or even the phenomenon taken on a sentence,

But this does not have materially affect to input process of the present invention, in addition also can be divided into keyword subject and predicate, guest, fixed, shape, benefit or directly with composition one, composition two, etc. form divide, this method is simpler but number of categories is less.

From the grammer angle,, can come selecting according to this requirement with keyword because the word that serves as sentence element is all had certain requirement.Here will point out, be to be based upon it is carried out on rule encoding (comprising the division to the speech) basis to the selection of word.These rules are used for guidance machine to the selection of keyword or say to debate and analyse.Because different speech has different contents, thereby it progressively can be segmented the difference of distinguishing between these speech.The rule encoding important contents is exactly the syntactic property of speech.On the other hand, all have some to debate easily in the various language and analyse and the very high speech of frequency of utilization, and these speech are significant to judging sentence type, the effect of other vocabulary of sentence in sentence etc., claim that here this class speech is a keyword.In addition, for specific sentence, also have some other debate easily and analyse and debating of whole sentence analysed the vocabulary that (this paper often the process that the fuzzy symbol of vocabulary is become the sentence of correct literal is called to debate analyse) provides quite a lot of information.Can utilize keyword and punctuation mark etc. that sentence type and each several part thereof are judged (also can key in the details about sentence type in case of necessity) like this, on the one hand.Can utilize the rule that sentence itself is had to wait further on the other hand again the sentence content debated and analyse and selecting with keyword.Thereby finally reach with machine fuzzy lexical information is organized into sentence this purpose with correct or suitable literal expression.Here an explanation to " suitable literal " is: Japanese Chinese and japanese Chinese character and assumed name often all are correct in sentence, but the former is more suitable than the latter sometimes; This paper will be used for the same keyword of keying in is screened and is used for the device of forming or be transformed into the correct or suitable sentence of literal is called the lexical analysis device.They are generally made with large scale integrated circuit, utilize syntax rule and the information about vocabulary that deposits in to come work, are one of most important devices in the blurred words key board entry technology.

Be similar to the Chinese Pin Yin initial input mode, can adopt with keyboard input for the input of alphabetic writing and form the initial of each or part syllable of this vocabulary and the mode of adding characteristic letter or adding characteristic symbol realizes.The characteristic symbol here can be that the further mark of division made in the vocabulary of keying in, so-called characteristic letter is meant that the initial of considering each syllable that only depends on the input Pinyin literal imports vocabulary and still have very big ambiguity, and therefore the second letter of first syllable of this word of additional input or last letter of this word reduce this ambiguity again.So-called characteristic symbol is the same with non-alphabetic writing can be with the input of word feature function key about the mark of the syntactic property division of vocabulary etc.To alphabetic writing, since gapped between speech and the speech, and characteristic symbol can be realized interval action simultaneously, so do not increase the keystroke number.When specific design, can further be simplified, as arbitrary english article is directly finished input with a keystroke the input of some character.

As a concrete fuzzy sets keyboard input application system, it can be a Word message process computer simultaneously, contain keyboard and output device, mainly comprise letter key, stroke key, be used for coming the literal of input information to represent key, cursor control key, punctuation mark key and in order to the image curve key of input picture curve and various print out equipment etc. with character or similar shape character in unison.Wherein the effect of image curve key is that literal or mathematical expression image represented curve are become geometric image curve, and image curve can be amplified, displacement and combination and change its color; Because input process needs demonstration, and shows more contents for making under certain display screen condition, can adopt the working method of each display screen time-sharing work or mutual exchanging contents.Certainly, above-mentioned keyboard system also can comprise more key, for example is used to import the function key of the Chinese phonetic alphabet four tones of standard Chinese pronunciation or the word accent of other Languages, the function key of secondary accent.

The fuzzy sign reversing of vocabulary is become the example of the sentence of correct Chinese character expression for a machine.The content of importing is: " had in my ordinary years one you, seem dynamic! " keyed in and content displayed be:

This is one 18 words, a comma and the sentence that finishes with an exclamation mark.Divide mark for part of speech in the square bracket.Since in the Chinese with "

D ", "

" for the pronoun of first letter of pinyin has only " I " and " you " two speech, at this moment also can be without the four tones of standard Chinese pronunciation.Again, in the Chinese with "

" be pronoun and noun for the preposition of first letter of pinyin has only " lining " and its front, so can know by inference " " and " lining " make sentence element three together, "

D " make sentence element and translate in the lump in " I " and ordinary years ".And can continue judge verb unique in the sentence "

L " make sentence element four, thereafter "

" make sentence element five and translate " one you " and infer: "

" make sentence element six and translate " dynamic ".Again because "

L " non-between point adverbial and concret moun " having had " do not belong to, and in Chinese, can and make sentence element six together with abstract adjective " dynamic ", with " D " be the verb first-elected " seeming " of Chinese phonetic alphabet syllable initial.Might as well be located at machine and " it seems " that this speech ambiguity is bigger, at this moment can with all possible " D " the expansion content of the fuzzy symbol of same keyword-be called vocabulary be presented at together to revise and ask manual intervention to be determined on the screen with final.This just finished from the fuzzy symbol of vocabulary to correct literal expression sentence this debate the process of analysing.

The fuzzy sets input method can make the typing speed of Chinese and other literal be enhanced about more than once, aspect from matter, continue 300 millisecond meters with a syllable, be converted into one second keystroke 4 times the thinking synchronous speed, this is that sizable some people is accessible after training.The word can also input operation person do not grasped as yet of this machine and have the ability of correcting mistakes to a considerable extent in addition.

The performance that content is concrete keyboard that key entry system is very primary.Generally requiring the fuzzy sets key entry system to have a keyboard, one is used to show by the lexical analysis device and finishes sentence that the vocabulary of analysis forms and the space of a whole page display screen of the article be made up of sentence and be used to show fuzzy symbol of being analyzed by the lexical analysis device of vocabulary and the modification display screen of expanding content and showing this analytic process thereof.They can be various chromatic liquid crystal screens.Function and reliability in order to increase keyboard reduce volume, can adopt a kind of like this dynamic hidden keyboard.Its structure is: the tactile keyboard that layer of transparent is installed on display screen (warding off the display screen as using CRT display screen, colour or black-and-white crystal display screen or forming with the luminescent diode array).A kind of fabrication scheme of concrete transparent touch keyboard is: with transparent piezoelectric, as the transparent piezoelectric pottery, be substrate, its lower floor evenly is provided with electrode with the density of three to five square millimeters of electrodes and is equipped with the thin wire of many band screen layers, then it is covered on the display screen and fixing.On piezoelectric, cover one deck electrode again.Because the voltage of piezoelectric effect is very high, so electrode and lead can make and very thinly very carefully make electrode with the metal of applying and can approach transparently fully.As for particular location, active area and the function of key, the present invention comes it is illustrated and limits with the display screen under the keyboard.And the keyboard space of a whole page that can be by selecting several immobilized substances or on other display screen, redesign a keyboard with existing keyboard and change function with extended keyboard with the method for the display screen exchanging contents of existing keyboard then.For this reason, agreement: the panel content change of the screen that the function of its keyboard can describe and limit with its function in the structure of dynamic hidden keyboard.

The dynamic hidden keyboard structure is the use of keyboard, especially for the use of pocket key entry system has brought a lot of convenience, but its when using hand can cover the part surface of keyboard.In addition, people's sight line also will move up and down observes display screen and keyboard, and for fear of these troubles and inconvenience, the present invention proposes a kind of shadow keyboard display technique.This shadow keyboard display technique adopts multiple display screen, promptly on a panel, show plurality of kinds of contents simultaneously, ward off as show the input content simultaneously, debate the process of analysing, keyboard content and with the relativeness plurality of kinds of contents such as (where being in keyboard) of detected hand of sensor (as using the electric capacity distributed sensor) and keyboard, so that the operator understands these contents simultaneously as each finger.The order of importance and emergency difference of coming performing content certainly with the concentration and the different color of color.This shadow keyboard display technique also can be saved a display screen and keyboard face and be enlarged the degree of freedom of hand except that above-mentioned advantage.Because this keyboard can be a levying property of picture, through the keyboard of large deformation very.Stipulate in addition: the display screen of time-sharing work, the display screen that can constantly change displaying contents also belongs to multiple display screen.Multiple display screen also can be used for other keyboard.

In general, the keyboard user always wishes to comprise more information and observes lighter on certain panel.For this reason, can adopt auxiliary panel display technique: comprise mode with projection and external display system, also comprise various display systems that keyboard system is contained by the whole or local content of panel is amplified or dwindle, modes such as shift in position and its color of change come content is shown or feature.The advantage of this auxiliary panel display technique is the eyesight that can save the operator.Also can adopt speech synthesis technique in addition, export for information about with sound.Like this can be at one time and the line output more information.

On the other hand, in order under the prerequisite that necessarily keyboard area and card content are comparatively stable, to obtain more input function and to make more convenient operation.The present invention proposes keyboard system, and especially various hidden keyboards adopt the Macintosh technology, and its content comprises: allow simultaneously by more than one key, and can come input information in this way.And different keys can have public part.This in fact Macintosh technology is the combination of each sensitive element of key, it is decomposed into more littler receiving elements or sensitive element with the receiving element or the sensitive element of common each key, thereby is used to import different information by the difference that these more receiving elements or sensitive element are distinguished the hand opsition dependent.In order the operator to be had gained some understanding, can adopt the effect that makes keyboard have employed key of timely demonstration and function thereof to the practical function of key.Concrete grammar corresponding each function key place on keyboard loads onto by this function key control and lights, the expression key effect light emitting diode or make the pairing display screen of keyboard, comprise that the multiple display screen that shadow keyboard display technique is used reacts to some extent to the action of key.

In order to import special character or image curve, can be used on the whole keyboard and to draw way input characters symbol and the image of writing, at this moment whole keyboard is with regard to all or part of of corresponding panel.

Accompanying drawing 1 has provided the keyboard layout of dynamic hidden keyboard structure of the embodiment of a pocket-size electronic typewriter of using the fuzzy sets input technology.In order once to key in the Chinese phonetic alphabet of the band four tones of standard Chinese pronunciation, the Chinese Pin Yin initial of 23 band four tones of standard Chinese pronunciation is imported with 23 four tones of standard Chinese pronunciation key groups, each four tones of standard Chinese pronunciation key group is made up of four keys such as key one (1), key two (2), key three (3), keys four (4), the corresponding respectively negative and positive four tones of standard Chinese pronunciation that get on.Each key group is marked with corresponding capitalization English letter, i.e. Chinese Pin Yin initial; Keyboard middle part indicates: " name, move, count, measure, be situated between, help, become, practise, special, generation, pair, shape, company, sense, its, calmly " key of printed words is the word feature function key, be used for and will be divided into 16 kinds of phrases or accurate phrases such as noun, verb, number, measure word, preposition, auxiliary word, Chinese idiom, expression, specific term, pronoun, adverbial word, adjective, conjunction, interjection, other phrase and self-defined phrase with keyword.In addition, three key groups of i, u, v mark can be used for importing the information except that initial, word feature or are used for control.Here do not plan to provide specific description.The top of this space of a whole page is the modification display screen (5) that can directly make amendment and handle displaying contents.But whole keyboard space of a whole page time-sharing work realizes importing the keyboard and the space of a whole page display screen effect (must keep operating key as the space of a whole page display screen time, certainly not take the space of a whole page and show) of usefulness respectively.This keyboard can be used on the space of a whole page to be drawn a mode of writing and imports.Available Chinese phonetic alphabet input Chinese character.By design, this keyboard is contained on the frame that comprises movement.Movement contains the driving mechanism and the interface device of printing device, power supply, various integrated circuit processor and storer and various magnetic-media recording elements.As frame being regarded as the very thick paper that two front covers clip, then between second page inside back cover, can sandwich printer paper.And open inside back cover and can carry out the message exchange that machine carries out with interface or magnetic-media recording element, can certainly display screen is being installed on the inside front cover and add the demonstration space of a whole page again between inside front cover and keyboard, this for multilingual contrast of great use.

Can adopt the Macintosh technology in order to increase keypad function.Produce five kinds of new functions by the adjacent combination in twos of four keys of four tones of standard Chinese pronunciation key group (promptly pressing simultaneously) and quadruple linkage are shared, can be respectively applied for monosyllable or polysyllabic word softly, information such as V-O construction, M-D (modifier-head) construction, foreign word, boldface type.The use also capable of being combined of word feature key.In full, amount two key combinations are used to import double-tone joint number measure word.Can make area with the space of a whole page shown in Figure 1 is 40 square millimeters of 200 centuplicates, the pocket Chinese typing machine of thick 30 millimeter.Tens thousand of words of internal memory or phrase.To point out in addition: can be based upon to design on the basis that is similar to the such standard information interchange code of USASCII to the rule encoding of word, word and the distortion thereof of various language and carry out, can significantly reduce internal memory like this, improve the processing speed of machine spoken and written languages.

Fig. 2 is a kind of keyboard space of a whole page of pocket Japanese typewriter, and available conventional method is imported.It is compressed to the input flat, katakana of each sound figure and voiced sound, half-voiced in female key of being demarcated by thick line (6).Available at most vertical sentence fine rules (7) and (8) of female key and mould sentence fine rule (9) are divided into six sub-keys, are used for importing respectively the putting down of sound figure and voiced sound, half-voiced, katakana.Certainly, the similar shape character keys of employing blurred words key board entry technology or the combination in twos of key add the word feature key again with anticaustic 51 keys and import Japanese, by the conversion of Realization by Machine fuzzy sets to correct well-formed sentence.But want to illustrate the key of public part here with this.When using this keyboard if with sub-key regard as independently key come with and need not misgivings and point by going out outside the key, because can set machine once at the most only to a key response, this definite functions but the second layer that the fuzzy key of boundary is a blurred words key board entry technology " blur " speech look like.

The fuzzy sets method can be imported the information such as grammer of word simultaneously, and this is extremely useful to further handle literal with machine.The various keyboard techniques that the present invention proposes can make people constantly introduce new stronger operating function along with the raising of keyboard operation ability.So refined abundant enjoying together has a kind of special charming.Finalize a text for needs are final artificial, the author think this and without difficulty, help the people to concentrate one's energy on the contrary, cause more inspiration, reduce and forget and improve the contribution quality.
