Abstract

The new bar code system for inputting data and operating instructions to computer has a character set including all the codes transmitted from keyboard to computer. These bar codes are associated with the actual meanings of their corresponding instruction or character to edit a operating manual. By scanning the bar codes on the manual, the instruction or data may be input to computer.

Description

A kind of bar code and carry out computer data input and method of operating with it

The present invention is a kind of bar code and with its new method with data and operational order input computing machine, belongs to the digital computer technique field.

Present domestic and international widely used bar code comprises UPC sign indicating number, EAN sign indicating number, intersects 25 yards, 39 yards, Ku Deba sign indicating number, 128 yards or the like, and its character set is generally the subclass of ASCII character, only can tens kinds of different message codes of direct representation.Even resemble 128 yards, the message code that can represent also has only 128 kinds.If the data beyond the input bar code character set just must realize by the way of software.

For example to import Chinese character " ", owing to there is not the ready-made bar code can this Chinese character of direct representation, must set up the corresponding relation of this Chinese character and a certain bar code combination earlier, as coming corresponding " " with four bar codes representing numeral " 1601 " (this numeral is the region-position code of " "), after bar code input " 1601 ", the method by software is with its " translation " one-tenth " " again.

This method programming is loaded down with trivial details, poor compatibility, thereby limited further applying of bar code: bar code fails to be extensive use of in the computing machine input so far, and only is used for the data automatic identification of some occasion.

On the other hand, present widely used computing machine as all kinds of microcomputers, generally adopts ASCII character as code for information interchange, adopts keyboard as the standard device that data, operational order is input to computing machine.This method makes computer operation inconvenience.The user must spend the plenty of time to learn the use of computing machine:

(1) since on keyboard only with pressing code that primary key can direct representation seldom, therefore many characters can't be directly inputted to computing machine, many codes must just can be input in conjunction with the way of other key with collateral keies such as CTRL, ALT, SHIFT and go in the computing machine, and code and its particular location on keyboard keyed in lack one-to-one relationship intuitively, so numerous computer users must spend the corresponding relation that great effort removes to remember, consult various characters and its correspondent button interdigit under the different situations, various data could be input in the computing machine and go.

For example, the general keyboard that uses, marked its implication commonly used on its each 1 key position: " A " key has marked " A " on the position, with explanation generally speaking, keying in " A " can be with small letter " A " input computing machine, under the situation of pressing SHIFT key or locking CAPS LOCK key, keying in this key can be with capitalization " A " input computing machine.

Such corresponding relation still is fairly simple, but problem is for different application purposes, need be input to go character and the operational order kind handled extremely many in the computing machine.Even only handle Englishly, except English upper and lower case letter, also have tab or the like, and when the other Languages (as Chinese) that computing machine is used to handle except that English, the character amount is just bigger.Can not mark simultaneously on the keyboard the various codes that might represent, this just need remove to get clear its corresponding relation according to different situations by user oneself.

For example: when computing machine was used to handle Russian, German, Spanish, French, the respective symbols when its each key position corresponding characters and processing English was just incomplete same, and user oneself must understand its corresponding relation again by consulting ways such as handbook.

For very big languages of character amount such as Chinese, Japanese, Korean, situation is just more complicated.At this moment in the ordinary course of things, the method that has been difficult to add with collateral key other key has been represented whole kinds of characters.So will use various coding methods, the code of character and several keys position is mapped, computing machine could be imported in character " indirectly ".

For example, for Chinese character, light one secondary simplified Chinese character just has more than 6,000.Theoretically, must key in several times key and could uniquely determine a Chinese character,, thereby will represent the information of Chinese character to import computing machine so people, establish the different corresponding relation (being encode Chinese characters for computer) of Chinese character and correspondent button position from various angle.The Five-stroke Method, configuration code etc. are exactly representative wherein.

But such method has many shortcomings:

1, finds it difficult to learn.No matter from the Chinese character of which kind of angle foundation and the corresponding relation of its corresponding encoded, the user must grasp the knowledge of this corresponding relation and some rudimentary knowledge of Chinese character itself and could use.

These input method of Chinese character of GPRS, for the general user, difficulty is very big.They must expend great effort and remove to learn relevant knowledge.

For example, if with Chinese phonetic alphabet input method to computer input of Chinese characters, the user must grasp the phonetic of Chinese character substantially, may also must (for example grasp the reduced form of these phonetics on keyboard substantially, some coding is represented initial consonant ZH, SH, CH that the user just must remember this corresponding relation respectively with A, I, U).If the user does not understand the Chinese phonetic alphabet, or unclear to the pronunciation of indivedual Chinese characters, then must spend a lot of times to remove to learn relevant knowledge, or be exactly that its Chinese phonetic alphabet is learnt by consulting reference in input Chinese character limit, limit, input service is usually interrupted, and speed is also just very low.

For another example, if input Chinese character by means of Wubizixing, the user must grasp the font structure of different Chinese character and the fractionation rule of the artificial regulation of this input method substantially, and some special circumstances also must be memorize mechanicallyd.If run into, import computing machine and then will expend the plenty of time and go to understand fully its structure earlier and split rule that this just greatly reduces the speed of Chinese character input certain yi word pattern or this font unconversant Chinese character of fractionation rule in the Five-stroke Method.

At present, many people have done a lot of researchs on the difficulty that reduces input method, and compare in the past, the input method that many learning difficulties greatly reduce also occurred, still, the reduction of difficulty is limited, can not continue without end, can not accomplish definitely need not learn.

2, do not meet people's thinking habit.The user must first coding method according to its selection convert Chinese character to coding when computing machine imported in Chinese character, this has just additionally increased user's thinking burden.

Labour intensity is big when 3, importing operation.Because the learnability and the efficient of encode Chinese characters for computer are a pair of contradiction forever, when adopting the input method of relatively easily learning, repeated code is often also many.Therefore when the input Chinese character, must note the information on the screen constantly, so that select correct Chinese character from several repeated code words.See that display is easy to eyes are caused damage for a long time like this, influence the healthy of user.

4, input speed is slow.For all the foregoing reasons, it is very slow to cause importing the speed of Chinese character.

5, take computer resource.Any input method all will be set up the coding and the one-to-one relationship of Chinese character in computing machine, and utilizes this relation that coding is translated into Chinese character, thus all must take a part of calculator memory, and may with other application software between produce and conflict.

6, adaptability is wideless.In general, input method of Chinese character only can solve the input problem of Chinese character, as for topic between the character input of tab, other languages etc., still must solve by the very low way of other efficient.Also do not occur a kind of at present to the blanket input method of above-mentioned various characters.

In sum, although obtained some progress on this problem of the input of other languages character (for China, mainly being Chinese character) outside solving English computing machine, this problem is not solved.The input technology of non-English languages (particularly Chinese character) remains the restriction computing machine and is used widely weak link.

For languages such as order literary composition, Korea's literary composition, situation is similar.

(2) want the operational computations machine, need a large amount of order of memory.In general, each computer software all has corresponding operational order, must just can make it produce the operation that needs after the necessary order of computing machine input.

For example, in WPS, tens orders are just arranged, represent to read a file as CTRL+K+R, CTRL+Q+E represents cursor is moved to the screen upper left corner, and CTRL+Y represents to delete delegation, CTRL+T represents to delete end of the sentence, and CTRL+U recovers deleted content or the like.

So various order, user or need spend the plenty of time to learn, or be exactly when using a certain software, must often consult reference, this just greatly reduces computed work efficiency.So many softwares adopt the way of so-called " user interface " well to alleviate user's learning burden, guide user's complete operation length by length as the way with menu prompt.But the user will have to note constantly the feedback information on the screen like this, and will be so long-term, weary the eyes very much, operating speed is also slow, and some its menus of English edition software uses English display often, many computer users is ignorant of English again, so do not reach prompting user's effect.In addition, the develop computer software person of going into has to spend great effort establishment user interface part, has influenced tempo of development.

And its order of different software also is incomplete same.For example, though use among the CCED with the intimate order of WPS, its form also is different.Equally, magnificent light composing system, upright composing system etc. all have the cover command forms of oneself.

Like this, even the user is familiar to a certain specific software, is using new software to relearning again, thereby expending great effort.This is to giving full play to the effect of computing machine, the very big adverse effect of having increased work efficiency.

Purpose of the present invention is exactly to solve above-mentioned variety of problems with a kind of succinct way, improves the result of use of computing machine, alleviates numerous computer users' burden.

The present invention is achieved in that

One, at first, create a kind of novel bar code, its character set comprises the whole different information (for various microcomputers, these different information are exactly scan code) that are transferred to computing machine from keyboard, and scanning can be imported computing machine with it with these data and the corresponding bar code of operational order.

For example, for character " A ", with keyboard be: on keyboard, press and the corresponding key of character " A " position with its process of importing computing machine, keyboard sends the scan code of this key position to computing machine, when discharging this key, keyboard sends release code to computing machine again, when computing machine receives these codes, handle by certain software again, scan code etc. is transformed into corresponding character " A ".

And for example, for collateral key " CTRL ", in general, it does not represent a specific character, and represents a subsidiary function.Similar to last example, when " CTRL " key position is pressed, keyboard sends a scan code to computing machine, but after computing machine receives this scan code, through software analysis, determine that its effect is not to import a character, but will make when " CTRL " key does not discharge, again by other key position produce one with separately by the different scan code of this key, so that produce different operations.So computing machine after receiving this scan code, does not produce any operation, when continuing to pin this key, when pressing other key, computing machine is accepted the scan code of these two keys, goes to carry out corresponding operation according to the regulation of application software.

Because scan code except will representing different characters, also will be represented other implication, so the total quantity of scan code is more than the quantity of ASCII character.For microcomputer, scan code has kind more than 500.

For this reason, the present invention has created a kind of new bar code, and the quantity of the different implications of its direct representation has comprised whole scan codes that keyboard sends to computing machine, in addition, some is used to show some scan code is carried out special processing, expands usefulness after some gives in addition.

Provide an embodiment of this bar code below.

This embodiment is the continuous type bar code, contains 13 identity element width in each bar code, and character discal patch or empty number are 3, and different implications that then can direct representation have 792 kinds.

For example: what represent respectively that a certain position (this position is an element width) of bar code go up to occur is bar, sky with 1,0, and first element of supposing this bar code is 1, last is 0, and (this is the character decision of the interpretation method and the continuous type code system of bar code, can certainly be on the contrary), then:

Available " 1000100000100 " represent scan code " 0 ";

Represent scan code " 100 " etc. with " 1011100001100 ".

Utilize this bar code that data, the order of importing computing machine are possibly encoded again.

For example, for the Chinese character input, owing to the ISN of each Chinese character is formed greater than 128 ASCII character with two code values, so can represent with the combination of two bar codes.

As, for Chinese character " ", the high byte of its ISN is " B0H ", low byte is " A1H ", if represent the scan code of " B0H " with " 1000001000010 ", represent the scan code of " A1H " with " 1000010011110 ", then the scan code of " " is made up of " 1000001000010 ", " 1000010011110 ".

During the combination of this bar code of actual scanning, the scan code that code translator sends to computing machine is with identical by the scan code of keyboard when computing machine sends two code values and is respectively the ASCII character of " B0H ", " A1H ".

And for example, for operational order F1, its scan code is 0, and 59H can represent with a bar code.

Two, secondly, above-mentioned bar code and represented implication thereof are combined, be organized in the operation manual.Operation manual can be according to different needs, the establishment of classifying.

Below in conjunction with Figure of description, divide three kinds of situations to provide embodiment:

Need to prove: problem for convenience of explanation, this instructions reflects following three kinds of information summaries, in fact can separate in an accompanying drawing.

(1) bar code is used for the order input.

Can be with bar code (or its combination) corresponding to various command, with the concrete implication of these orders, layout is in operation manual together.

For example, can be with bar code (or its combination) corresponding to every order of WPS, with the concrete implication of these orders, layout is in one page that aims at the WPS procedure service (or several pages) together.

In the accompanying drawing, 1 is the implication of each order, can also explain more in detail certainly; 2 for corresponding respectively to the corresponding bar code of each order.

Like this, as carrying out " preservation file " operation, just needn't see screen again, directly the bar code that should order is got final product with light pen or the scanning of other bar code scanner, code translator will send the scan code of this order from the trend computing machine, thereby make computing machine finish corresponding operation.

(2) bar code is used for cursor and moves.

Operation for convenience where necessary, can connect position and its implication of some page of operation manual of the bar code of expression cursor movement key, some operational order.

For example, in the accompanying drawing, 3, the 4 bar code combinations of representing respectively corresponding to the same implication of " → ", " ↓ ", when continuous sweep 3 from left to right, after decoding, will produce the scan code identical continuously with cursor key " → ", its effect is with identical by " → " key continuously, like this, cursor movement key and its real meaning will be connected intuitively.

Otherwise, when continuous sweep 3 from right to left,, can make it after decoding by designing suitable bar code translator, produce the scan code compatible mutually continuously with keypad up-arrow key " ← ", its effect is with to press " ← " key continuously identical.

In like manner, when respectively from top to bottom, when scanning 4 from bottom to top, after decoding, also will respectively continuously and produce and keypad up-arrow key " ↓ ", " ↑ " identical scan code, its effect with on keyboard, press " ↓ " continuously, " ↑ " key is identical.

In addition, in the accompanying drawing, 5,6,7,8 expressions and WPS order " first ", " to the screen end ", " to nextpage ", " to last page or leaf " corresponding bar code combination respectively to screen, its position just get in touch to some extent with its physical meaning (promptly first to screen, to last page bar code position in the upper left corner of this one page.And to shielding the end, arriving the bar code position of nextpage in this one page lobe lower right corner).

9 expressions are by the combination that combines with cursor key " ↑ ", " → " corresponding bar code respectively, this bar code combined printing one-tenth and horizontal line are at angle, and the ratio of these two kinds of bar code numbers in combination is relevant with this angle, angle is more little, many more in the combination with the corresponding bar code quantity of " → " key, this combination of scanning is equivalent on keyboard alternately with different number of times by " ← ", " ↓ ", " ↑ " " → " key like this, can be more intuitively, with direction moving cursor on screen of bar code layout direction basically identical.This method can partly replace the effect of mouse under less demanding situation.

Same principle can be used for the operation of other software.

(3) bar code is used for the character input.

Be input as example with Chinese character.

Can be with various Chinese characters, speech, phrase or tab and its corresponding bar code (or its combination), by certain logical communication link layout together in operation manual.

For example, Chinese character, speech and phrase " meter ", " calculating ", " computing machine ", " computerized information " and corresponding bar code combination layout thereof can be in the same place, as shown in drawings.

Among the figure, 10 is Chinese character, speech or phrase, and 11 for corresponding respectively to the corresponding bar code combination of these Chinese characters, speech or phrase.

Like this, as importing Chinese character or phrase " meter ", " calculating ", " computing machine ", " PC World " respectively, directly scanning gets final product corresponding to the bar code combination of this Chinese character or phrase, code translator will send the scan code of this Chinese character or phrase from the trend computing machine, after computing machine receives this scan code, will with the same corresponding operating of carrying out of corresponding scan code of accepting keyboard input.

In like manner, 12 is to make up corresponding to tab Bar code combination, scanning this bar code combination can directly tabulate.

As in operation manual, layout and corresponding other languages literal (as Russian, Japanese etc.), symbol etc., promptly available same manner is imported computing machine with it.

The present invention with existing be that the computer input method of instrument is compared with the keyboard, following obvious advantage is arranged:

1, simple and convenient and easy to study.As when being used to import Chinese character, need not to learn any coding fully, as long as understanding Chinese characters can find corresponding bar code in operation manual, with its input computing machine.

2, the thinking habit that meets the people.People often get used to the word that writes with a pen, and the present invention can import with light pen, method of operating with write very similar.Particularly when the input Chinese character, need not any thinking transfer process, method of operating is almost completely the same with the word that writes with a pen.

3, function can expand arbitrarily.As want to expand and desire to be input to the data of computing machine and the kind and the quantity of operational order, as long as by the corresponding bar code of corresponding rule establishment.Although the bar code of the order of different software, kinds of characters has nothing in common with each other, the information on the operation manual is very intuitively, for the general user, as long as understand this surface, has saved the energy of study computer operation greatly.

4, operation is directly perceived.As operations such as moving cursor keys, common keyboard is used by the cursor movement key operation, and intuitive is poor, and utilizes method of the present invention, and cursor can be accomplished to move with consistent direction, speed with light pen, very visual pattern.

5, input characters without repeated code.Because bar code or its combination can accomplish that with Chinese character, operational order strictness is corresponding one by one on code, thus when utilizing the present invention to import Chinese character for a long time the feedback information on the observation display carry out the repeat code Chinese character selection, can accomplish touch system fully.

6, working strength is low.Utilize method of the present invention, when carrying out data in enormous quantities input, need not to see for a long time the feedback information on the display, alleviated working strength, improved work efficiency, be of value to health of operators.

7, input fast.Because above-mentioned various advantages are faster with the keyboard input at present with method input data ratio of the present invention.

8, do not take computer resource.Method of the present invention and traditional complete compatibility of keyboard input do not need to increase any handling procedure, and be compatible fully with existing various softwares, thereby very easily promote on active computer.

9, with low cost.At present, many computing machine scientific research personnel are being engaged in the research that data (for China, mainly being Chinese character) is input to computing machine in the handwritten form mode, say technically, it is very big that this method implements difficulty, and discrimination is difficult to reach practical requirement, and cost is also than higher.

By comparison, method of the present invention is skillfully constructed, technical difficulty is very little, and input speed is faster, and (Chinese character hand-written identification needs the user that each word is neatly write out, otherwise computing machine just is difficult to identification, and the present invention only needs the user to find and wants the corresponding bar code of the character of importing, scan with light pen and to get final product, and the phrase of can single pass forming by several words, faster certainly), discrimination is high, and cost is also much lower.

It may be noted that, the present invention can have multiple embodiments, as having nothing in common with each other owing to implementing computer system of the present invention, perhaps because science and technology development, thereby variation has taken place in the mode of exchange message between computing machine and its peripheral hardware, and these factors all may cause the character set generation respective change according to the bar code of principle generation of the present invention.In addition, those skilled in the art also can be on basis of the present invention, some details are changed, as change the arranged mode of operation manual, layout can be applied to the corresponding bar code input operation handbook of the vocabulary of new professional domain, and bar code symbologies is not had the substantive change of creating, or the like, but these do not influence essential characteristics of the present invention, thereby must be considered as having used the present invention.
