Description

Quasi-Three-Set Hangeul Keyboard and New Universal Keyboard System}

The present invention relates to a method of inputting Korean or English using a character input keyboard to an electronic device using a computer, and a keyboard arrangement related thereto. All character input systems for inputting characters through the keys of the keyboard using a user's finger, etc. become a technical field to which the present invention can be applied. As a specific example, the keys are implemented as physical entities, such as a conventional computer keyboard. A button-type keyboard and a touch screen keyboard of a relatively recently developed smartphone are mentioned.

This application contains patents related to Hangul theory, keyboard theory, historical considerations of Korean and English keyboards, character system theory, and fonts necessary to properly understand the design and development of character input keyboards for efficient input of Hangul. In terms of information disclosure, which is an important function of the system, it is comprehensively and comprehensively described. Because of the structure of the patent document, it is difficult to easily grasp the overall outline of such a vast content, so a brief summary of the overall summary is attached as an appendix at the end. Will be

The present invention relates to a character input method and keyboard layout for inputting character information mainly composed of Korean characters into an electronic device using a computer. The character input keyboard began with English typewriter keyboards developed more than one hundred and thirty years ago, and the Hangul keyboard was the first practical Korean typewriter developed in 1950, and the standard two-bulb keyboard that appeared in the process of unification of the keyboard and the subsequent keyboard unification. In the process of developing computer keyboards in the latter half of the century, there has been a debate on the keyboard, but now it is still stuck to the standard double-key keyboard that still has many problems.

In the midst of the development of wireless communication, the character input keyboard continues to develop as its importance moves to the touch screen keyboard used in smartphones and tablet PCs, etc., which recently appeared through mobile terminal keyboards. Current trends suggest that touchscreen keyboards will be overwhelmingly used to enter small amounts of information in small electronic devices, such as communication devices, and smartphones and tablet PCs will dominate the market for desktop and notebook computers. . However, computer keyboards with all ten fingers by touch type will still remain an important character input means for inputting a large amount of information. Therefore, it is predicted that both touch screen keyboards such as computer keyboards and smartphones will be important means of character input in the foreseeable future.

In the present invention, the Hangul input method developed by reflecting the characteristics and principles of Hangul is applied to both touch screen keyboards such as computer keyboards or smart phones, but the two types of keyboards have different characteristics from each other in many respects. The points to consider in applying the invention are also very different. This will be discussed in more detail in the solutions and the effects of the invention.

A. Compatibility and Conformability of Standard Keyboards

Since one of the main applications of the present invention is an improved application of a keyboard called a 101 / 102-key standard keyboard or a universal keyboard, a brief term and definition thereof will first be described. Figure 1 shows the overall appearance of the 101-key standard keyboard, among which the touch type area (touch type area, 100) is the main application of the present invention, the keyboard having a QWERTY English array and a standard double-bulk Hangul arrangement The palpable batter area of is shown separately in FIG.

The reason for this is called the 101 / 102-key standard keyboard because the total number of keys included in the IBM computer keyboards of the 1980s was 101 in the United States, but 102 in Europe, with one more key beside the left shift. . After that, Microsoft added two Windows keys and one menu key, and most of the keyboards currently used in the United States have 104 keys and 105 in Europe, but in the East, Korean, English, and Chinese With the addition of the function keys, the actual keys are five or six more than the original 101. However, since almost all keyboards used all over the world basically include 101 or 102 keys in the first place, they are collectively referred to as "101 / 102-key standard keyboards". 101-key standard keyboard ".

The present invention relates to the efficient use of the comfort touch type areas (101 and 102) among the touch type areas of the 101-key standard keyboard. Refers to a combination of keys that are within about one key distance from the home key of the finger.

The alt (129) on the right side of the space (SPACE, 127) is sometimes written as AltGr for the purpose of inputting special characters, which are treated as compatible. . In a relatively recent 101-key standard keyboard, a function (Fn, 128) key may be added next to a control (CTRL). The keys in the tactile typing area can be divided into general keys used to input characters or symbols and function keys that perform any action or action, such as SHIFT or ENTER.

Figure 3 shows the hexadecimal number of the identification number in order to systematically represent the keys to input the general key, that is, letters, numbers, symbols, symbols, etc. except for the function key and the space key in the present invention, The first digit represents a column and the second represents a column. The palpating batter area includes the first row 115 of the uppermost row, the second row 116 of the upper row, the third row 117 of the home row, and the fourth row of the lower row. 118), five rows of five stages (119), the lowermost row, and fourteen columns (90 to 9D), all over the left column 0 (90) to the right column D (9D). . For example, the “ㅁ” key on the standard double keyboard, ie, the “A” key on the QWERTY keyboard is 31, and the “ㅔ” key on the standard double keyboard, or “P” on the QWT keyboard. It is represented by 2A because it is a two-stage A row key. In the present invention, when referring to a key of a computer keyboard, unless otherwise specified, an English keyboard uses a character assigned to the basic place of the QWERTY keyboard, but when the letter is a lowercase letter, a corresponding English uppercase letter may be used. For example, the three-stage single row key 31 denoted as "A" may be denoted as "a" depending on the situation. However, in the case of the Korean keyboard, we will refer to the keys using the Korean characters specified in the keyboard layout under discussion.

In the present invention, the compatibility of the keyboard (Compatibility) means that all keys in one keyboard in a similar position of the other keyboard in hardware, Conformability (conformability) is used because of the similar character arrangement between the two keyboards It is defined as the degree to which a person can easily change to another keyboard. Thus, if compatibility is required, all keystrokes can be easily changed in software, so that a new keyboard can be implemented and installed without purchasing a new physical keyboard, and a compatible keyboard layout can be easily selected and used at any time. For example, a 101-key standard keyboard used worldwide has a modified structure, such as 133B of FIG. 4 or 133C of FIG. 5, depending on the region of the right portion 133A of the keyboard, but they are all fully compatible with each other. For example, Qwerty and Dvorak keyboards implemented on the same 101-key standard keyboard have no compatibility problems, but they are almost inconsistent because their character arrangements are very different. The Hangul keyboard has the structure shown in FIG. 4 mainly on the right side of the keyboard. However, in the present invention, the structure shown in FIG. 3 will be described for convenience.

B. Character input method using compound key

The keys of the tactile typing area can be divided into the general keys used to input characters and the keys used to perform a function or function. The 101-key standard keyboard has 47 regular keys all in the touch type area, so only 47 characters can be entered using a single key. Therefore, to input more characters, you must use two or more keys, that is, compound keys. Here, after the various methods of inputting a character using a compound key and related terms, we will define a unified term and a notation method to be used in the present invention.

1. Delayed simultaneous input method

Shift, Control, Alt, AltGr, etc., are used in combination with other generic keys to type characters or computer characters that are different than when the generic keys were used independently. It is usually called a modifier key by having it perform some other command. The most basic method used to increase the number of characters that can be easily entered is to combine shifts with regular keys so that shifted characters different from unshifted characters are entered. In general English keyboards, the function is limited by increasing the number of characters that can be easily input by doubling the number of general fonts. In European keyboards, Altzial lets you enter a larger number of letters, symbols, and symbols. An array of keyboards that have been changed using a variable such as shift or Altzial is called a level. The array of characters entered when using a single key is called the default level or the first level, and the other levels are the second level. It is called a 3rd level.

A key is usually unresponsive even when the key is pressed for a long time. The input assigned to the combination is made only when another key is pressed while the key is pressed. As such, there is no proper term for a method of inputting by pressing another key while pressing one key. Thus, in the present invention, the delayed simultaneous input method is called, and the "_" Shift_a ”,“ Control_c ”,“ Shift_Control_v ”,“ Alt_k ”, etc. will be described. Using the shift or Altzial not only are these keys located in an inconvenient place, but the operation required by the delayed simultaneous input method is very inconvenient and takes three times as long as the use of ordinary keys. On the other hand, the correlation of I / O is expressed as “Shift_a → A“, “B ← Shift_b”, etc. by using the right arrow or the left arrow, and any unspecified number of keys are marked by the “?” Symbol. Shift_? ”,“ Control_? ”And so on.

2. Sequential input method

In general, when a short key is pressed and released shortly, the letter assigned to the key is sequentially inputted. This is called sequential input and is marked as “ad” using the “-“ sign. Normally, when the general key is pressed for a certain time, the character corresponding to the key is repeatedly set. When two general keys are used as sequential inputs and used as compound keys, one key is the base key for entering the base character and the other is the operator that acts on the base character. in many cases. The first key is used as a function key is called the dead key method, the second key is used as a function key is called the function key method. For example, if the “` ”key is set to a function that inputs a grave accent, the dead-key method uses“ `-a →

”, In the function key method“ a- `→

"in

Will be entered. In a sequential input, the base or agonist may be a compound key with a hinge. For example, if “Shift_`” is set as a dead key to input a tilde accent.

Shift_`-a →

"in,

Shift_`-shift_a →

Is entered.

The name of the dead key is because there is no response after typing the key, but after the key is entered, the characters assigned to the combination appear on the computer screen, which is a kind of ghost fire phenomenon. I will. In the function key method, the base character is entered first and then appears on the screen, so the user enters the function key while looking at it. However, the agonist method is not well written because its implementation is complex. The name of the acting method is a name given when the acting key is written, which is not appropriate because the dead key method is also used. Therefore, in the present invention, the dead key method is called a pre-operator method, and the actuating method is called a post-operator method, and the corresponding actuating method is referred to as an aforesaid and a rear organ, respectively.

3. Simultaneous input method

In the input of a compound key consisting of two or more general keys, a method of inputting all the corresponding keys within a predetermined short time, which the user feels to be simultaneous, is a chorded input or a simultaneous input method. This is called. This method is not well used for special purposes such as shorthand keyboards or very few keyboards due to the characteristics of Western languages, but it is very suitable input method for Japanese and Korean and its implementation is simple. However, to input any number of keys at the same time, an n-key rollover keyboard is required. Since the common keyboards are 3-key rollover keyboards, there is no guarantee that three or more keys can be entered simultaneously. none. Simultaneous input will be marked with “` + a ”or“ a + `” using “+” sign. On the other hand, when both sequential input and simultaneous input are allowed, “` -a ”and“ `+ a” are compressed by “` ± a ”using“ ± ”symbol. In addition, in the case of simultaneous input, one of the keys may be a working key and the other key may be a back key, and a key serving as a working key in the simultaneous input is called a co-operator. However, as in the case of Hangeul vowels (eg “ㅗ + ㅏ → ㅘ” and “TT + ㅓ + ㅣ → ㅞ”), none of the keys that make up the combination may act as a functioning key.

C. Background and Problems of Korean Keyboard

There has been a vigorous keyboarding debate on Hangul keyboards since the late 1960s and through the 1990s, but most of the problems raised for standard double keyboards have not been resolved. . The current standard double-bold Hangul keyboard has several serious problems, although most users are not aware of it. The term “governmental standard” two-key keyboard is often used, which is a dissatisfaction of perceptive Korean experts on the standard two-bolt keyboard. However, in the keyboard debate of the past, most people overestimated only the merits of the two-party camp and the three-party camp by arguing with each other that they overestimated the merits of each other and derogated or rejected the wrong ones. There was almost no.

Disadvantages of the standard two-key keyboard can be divided into disadvantages due to the lack of three-way type and the disadvantages related to the layout of the keyboard. First, the disadvantages related to the keyboard layout are listed as follows.

1) The use of the left hand is too high because the left hand is responsible for the initials and the seed.

2) Since both the initials and the final characters are input with the left hand, the battering rate and the battering rate are high. Increasing the winter batting rate, the batter input speed is lowered, and the error rate is increased.

3) All the neutrons are arranged on the right side of the keyboard. Only “ㅠ” is placed in the position of the left hand index finger and works with the other five keys that use the left hand index finger.

4) The consonant “ㄹ” is assigned to the index finger of the left hand. This key works with the vowel “” and the four consonant keys “”, “”, “”, “” and syllables. Or, since the overlap is entered, the winter batting average rate is increased. This could theoretically enter up to seven hits on your left index finger.

5) Inefficient use of high frequency neutrons, “ㅠ”, “TT”, and “ㅡ” is arranged at the bottom of the keyboard. According to the keyboard theory, the stop, which is the reference stage, is the easiest to input, and the more difficult to enter in the order of top, bottom, and top.

6) High shift utilization reduces input efficiency and increases error rate.

It often points out the shortcomings of the standard pairs of keyboard layouts and condemns that the standard pairs are very wrong. The shortcomings of the above standard double arrays have been recognized by experts long ago, but simply changing some of the phoneme arrangements of the two pairs to solve the shortcomings does not solve the root of the problem, but only adds confusion. Therefore, you have to use it as many times as you can't do wrong arrangement. However, the standard two-row arrangement is such a well-designed arrangement within the two-bolt structure, and it can be said that it is close to the optimal arrangement in the two-bolt structure by modifying the arrangements pointed out above. Judging from the keyboard theory, the standard double-bolt arrangement is a very good arrangement, at least compared to the QWERTY array. It is estimated that the input efficiency of the keyboard is only 30% compared to the Dvorak array, which is the wrong array of QWERTY arrays, and as a result of the efforts promoted through the years, Dvorak keyboard was the second standard in the United States in the early 1980s. Even today, more than 30 years later, the Dvorak keyboard is still used only by very few people, and the Korean version of the Korean standard keyboard is very suggestive. In other words, the history of the American standard keyboard may lead to the hasty conclusion that the revision of the Korean standard is meaningless.

However, in the case of Hangul keyboard, the conclusions can not be drawn from the example of Qaty and Dvorak keyboard of English keyboard because the unique three characteristics of Hangul are the core of Hangul computerization and Hangul informatization, and that is the key to Hangul character development. . Therefore, the biggest and fundamental problem of the standard two-bolt keyboard is that it is not a two-stage type but a two-stage type. Since the standard two-bolt keyboard is a two-bolt type, users cannot enter the initial and final characters separately, and thus, it is not possible to efficiently distinguish the words. Therefore, the following problems arise. The original constraint of ".

1) ghost fire occurs.

2) It is not possible to input or output the distinguished phoneme and the beginner phoneme separately.

3) The Korean keyboard standard, the character input standard, is different from the Korean code system standard.

4) Nowadays, the Korean and old Korean dials can not be unified.

5) It is difficult to expand to Saehan Hangul necessary for foreign language writing for academic research.

As shown in Table 1 below, the first goblin phenomenon is that when you input Hangul with a two-bulk type keyboard, the consonant is attached to the final position of the syllable at the output of the screen and then moved to the initial position of the next syllable. Visual disturbances appear. Many people feel strange or uncomfortable with this ghost fire when they first learn the keyboard, but they often dismiss it as not a big problem and forget that it was a problem.

Other disadvantages of the second or less are that the general public who uses the keyboard does not recognize or feel uncomfortable at all. Therefore, based on the public's opinion on the ease of use of the keyboard, it is impossible to hope to revise the keyboard standard, and the writing system experts of academia and government related organizations lead the standardization revision to the keyboard having three characteristics for computerization / informatization of Hangul. Should.

Since the three-key keyboard is essential for the development of Hangul characters, the above shortcomings will be further explained. The keyboarding of the keyboard is closely related to the Hangul coding system that represents Hangul in the computer. The keyboarding and Hangul coding system of Hangul keyboard are the core of the computerization of Hangul. Therefore, the Hangul keyboard is more than simple input, it is closely related to the efficiency of Hangul information processing such as retrieval and sorting of the information stored in the computer, which greatly affects the development and development of Hangul in the computer age. For example, the Korean code system included in the international standard code system ISO / IEC10646-1, which was confirmed as an international standard in 1992 (Korea translated it almost in 1995 and established the Korean standard code system KS X 1005-1). In Korean, separate code values are given by distinguishing the initial and final characters of Hangul. For example, the sign of the initial letter a is 1100 and the sign of the initial letter a is 11A8. However, in the current standard double-type keyboard, there is no way to enter the first a and the final a, which are distinguished from the standard coding system, because there is only the letter of the consonant a which combines the first and the final a.

In Hunminjeongeum, it is possible to use a combination of up to three basic elements such as neutrons, neutrons, and neutrons. In addition, many forms of new Hangul for foreign languages are being discussed nowadays, which can not be properly done with a double keyboard. Any combination letter, for example,

Can be written by hand, but the fact that it cannot be input to a computer is a serious problem that limits the ability of Hangeul, regardless of whether or not it is inherent, and is a barrier to Hangeul development.

In order to solve the above problems, various methods have been proposed as an alternative to the standard double keyboard. The most insisted type of keyboard is the Gongwoo-woo Sebul-type keyboard, which is currently used in two types, the final type and the 390 type, which are almost similar. Gong Woo-woo's keyboard was first developed in 1948, much earlier than the standard two-key keyboard, and has been steadily improved for twenty-three years at the time of the keyboard debate, and has received much support from the public and keyboard experts. While such an engineer's keyboard has been unjustly suppressed by the regime at the time, it is now used by only a small number of people, but meaningful people, such as Sesamo, are still calling for the national standard keyboard of the engineer's keyboard. However, Gong Woo-woo's keyboard was better than the standard two-key keyboard at the time of the keyboard debate, but its advantages were diluted due to the development of computers and the possibility of mechanical typewriters no longer being used, and now it is more likely to replace the standard two-key keyboard. Not only can we not expect it, but if we evaluate it with the current keyboard technology, it is not enough to become a standard keyboard.

The biggest drawback of Gong Byung-woo's keyboard is that it is difficult to learn and learn how to use the keyboard, more than twice the number of Korean letters assigned to 58 letters. In addition, it is not desirable that the arrangement of numbers, punctuation marks, and special symbols differs significantly from that of English keyboards because Korean letters are arranged up to the top of the keyboard. Advocates of the Sebul-eung keyboards insist on unity with mechanical keyboards when referring to the unification of the keyboards, but now that the possibility of using mechanical keyboards is no longer used, rather than unity with English keyboards, these days Korean input and old Korean input methods, Unity with the foreign language Hangul notation input method is much more important. In other words, the issue at the time of the keyboard debate was Hangul mechanization, but now we have to think about a keyboard suitable for computerization and Hangul information. Therefore, at this point, an advanced Korean keyboard designed with Korean code system and Korean font generation method in mind is required.

In 2000, masseuse keyboards were developed, but they were not widely accepted. The massage keyboard has only 10 independent keys, 10 neutrals, and 10 final fonts, and the rest of the Hangul alphabets are input by the combination of these independent keys. It is characterized in that the ultra-fast input through. However, the massage keyboard is a difficult keyboard for the general public to learn because the keyboard is input by pressing up to eight keys at once. In addition, in order to properly utilize the simultaneous input of the massage keyboard, a general keyboard often cannot be processed properly when three or more keys are pressed at the same time. Therefore, a special keyboard having an n-key rollover function is used. need. In the massage keyboard, the arrangement of punctuation marks differs from that in the English keyboard because the number of basic keys is four more than the number of 26 English alphabets.

In order for Hangeul to be developed through computerization and informatization of Hangeul, it is a consensus among Korean experts who have knowledge of Hangeul code system. However, the three-separation ceremony does not necessarily mean that the three keys of the elementary, middle, and cultivators must be separately provided. Lee Il-Byeong's proposed Q2.5 bee type was actually a double bee type, but it is a semi-separated type that allows you to enter the seed by distinguishing it from the first person by using the shift as the final key. From the technical point of view of Korean computerization, Lee Il Byung keyboard, as pointed out by computational Korean scholar Kim Kyung-suk, has no problems in general, and it is more appropriate to see it in three-separation style (Kim Kyung-seok, Hangeul Story in Computers). , Pp. 319-320). However, the two-stroke keyboard failed due to the excessive number of times the shift was pressed. The reason for the use of the shift key is about 2.2%, compared to the 2.2% of the shift used for input of double consonants in the standard double-bolt type. 18.7%.

The term dubbed keyboard has different meanings in typewriter keyboards and computer keyboards. Since the experts of keyboards lack understanding of it, it seems that wrong arguments have been raised in Korean debate. Summarize the term semi-separated keyboard. In the classification of computer keyboards, the two-bolt type has only two keys and the user enters the seed without distinguishing it from the first person when the user enters it. Enter differently from saints, and have three keys in three sets. However, this classification does not apply to typewriter keyboards. Typewriters have been categorized into two- and three-seat types. However, the double type in the typewriter is semi-separated as the computer keyboard classification standard because the user inputs the distinguisher from the first person by using the shift, and the double type of the computer keyboard classification standard cannot exist in the mechanical typewriter. The double style of computer keyboard and the double keyboard of typewriter, together with this conceptual difference, has a huge performance difference because of the 20% use of shift in double typewriters. Table 2 shows a comparison between the typewriter keyboard and the computer keyboard.

Table 3 compares the type and number of keys used by each keyboard and the method of input for typical Korean keyboards including the standard two-bolt keyboard. In addition to the above-mentioned keyboards, this table includes North Korean two-bolt keyboard and two shorthand keyboards. For convenience, the data of the new quasi-separated keyboard developed in the present invention were also shown in advance.

So far, published articles on Hangul keyboards have always dealt with Hangul characters that are input using shift as separate keys, but this is not reasonable and is not appropriate. In the present invention, it is determined whether the calculation in a separate key on the basis of the following rational more reasonable. In other words, when two or more keystrokes enter a phoneme in combination, if there is a clear and easy association between the phonemes assigned to the key used in the combination and the resulting phoneme, then it is treated as a combination key, and no association is made. If it does not help remember the position or combination of the key, it is treated as a separate key. For example, the double consonants ㄲ and 입력 input using the standard double-shift type are easily related to the single consonants a, c, etc., so they are viewed as a combination of shift, a, c, etc. Since the phoneme input when used with shift and the phoneme input when used alone are not related, they are treated as separate keys. In Table 3, it can be noted that the new quasi-separated keyboard developed in the present invention uses the least number of keys and uses a systematic and simple combination, and there is no use of the shift in question.

In relation to the conventional Hangul keyboard, a correlation between the increase in the complexity and the performance improvement of the keyboard is conceptually shown on the basis of the current standard keyboard, which is a standard double keyboard. Although the performance comparison of the keyboard shown in FIG. 6 is both qualitative and subjective, it is also based on objective and quantitative analysis data based on keyboard theory. However, there are subjective and qualitative aspects depending on which of the numerous considerations to consider in the keyboard are given more weight. However, the conceptual concept here is that to replace a standard keyboard requires a significant performance improvement with minimal change from the standard keyboard. The previous keyboards eventually improve performance compared to the increased complexity of the keyboard. Is relatively too small to fail. For convenience, the newly developed keyboard in the present invention is also shown in the conceptual diagram of FIG. 6, but it can be hoped that maximization of performance versus complexity is aimed at the new Korean keyboard.

D. Background and Problems of English Keyboard

The worldwide universal keyboard now has the basic structure of the 101-key standard keyboard shown in FIG. Since the tactile typing area 100 of the keyboard is based on the basic structure of the QWERTY typewriter developed more than 130 years ago, it has two main problems. The first problem is the inefficient English array of QWERTY keyboard.

1) Home Row Ratio (HRR) is too low.

2) Successive Same Hand Ratio (SSHR) and Successive Same Finger Ratio (SSFR) are too high.

3) The row transition ratio between the top and bottom is too high.

4) Use your left hand too much than your right hand.

The second problem is related to the basic structure of QWERTY keyboard, which is due to the fact that current computer keyboard developed from typewriter keyboard and applied to English keyboard as well as English keyboard based on English keyboard. same.

1) The number of numbers, punctuations, and symbols that can be easily entered is limited to 42. This is not a problem when only English is used, but in the Unicode era, which aims at internationalization and multilingualization, it is easy to input various characters or symbols in an intuitive and systematic way. The demand for it is increasing.

2) The use of shift pads is inefficient. In order to input the uppercase letters of English and most symbols or symbols, you need to press the general key while holding down the shift first and spread the weak force wide to the edge of the keyboard. It takes three times as long.

3) Since the backspace used for correcting a typo is about 7cm away from the reference position of the right hand, it is necessary to spread the hand excessively or move the entire right hand when correcting the typo. This is greatly reduced.

4) The basic structure of the keyboard and its current tactile methods do not properly reflect the structure and operation of human hands. The thumb is an agile finger that is not only the most powerful cell but also the largest bundle of nerves, which works best with other fingers. This fact can be easily confirmed by hand gestures when holding objects by hand. In addition, while the other fingers are difficult to press two keys simultaneously with one finger, the thumb is very natural to press two keys simultaneously with one finger, an example of which can be seen in Korean shorthand keyboards. In this regard, current keyboards and tactile methods, which use both hands' thumb only for input of space, have room to improve ergonomics, and more efficiently use the space of the keyboard occupied by useless long keys. It needs to be improved.

In order to solve the above problems of the QWERTY keyboard, numerous keyboards have been proposed, but the number of practical keyboards is very few and the QWERTY keyboard is still used more than 99%. The biggest reason why the inefficient QWERTY keyboard still maintains a firm position as a roll-through keyboard is that the use of the keyboard is learned through repeated practice, making it difficult for users who are adapted to the existing keyboard to switch to other keyboards. Because.

The English keyboard alternatives, which had received a little response, were characterized by the Dvorak keyboard, which was designated as the American standard keyboard in the 1980s, the Maltron keyboard that stands for ergonomic structure, and the high speed input with syllable unit simultaneous input. Veyboard and Colemak keyboards feature multilingual input using Altzial. The Colmack keyboard was released in 2005, which was relatively recent, but it is the third most popular and the fastest growing number of users after Dvorak. This reflects the need for multilingual input in the Unicode era.

For the previous English keyboard and the English keyboard implementation of the present invention, the correlation between the complexity increase and the performance improvement of the keyboard is conceptually shown based on the current QWERTY keyboard. In the case of the Dvorak keyboard, the typewriter keyboard and the computer keyboard are shown separately, which means that the arrangement of the alphabets in the typewriter keyboard means that the two keyboards are not only consistent but mechanically incompatible. The difference in arrangement is that full compatibility is ensured through the use of keyboard drives implemented in software. Among the previous keyboards shown in FIG. 7, the Dvorak keyboard and the Colmack keyboard are compatible with current keyboards, but the Maltron keyboard and B board have completely different basic structures. All of these keyboards also had compatibility problems in part because they only partially solved the above-mentioned problems of the QWERTY keyboard, and thus failed to replace the QWERTY keyboard. In addition, all other keyboards except Colmack keyboard lack the ability to input various characters other than basic codes or symbols. In addition, a number of keyboards attempted to make thumb shift keyboards that greatly increased the utilization rate of the thumb by moving the function keys on the edge of the keyboard to the bottom center of the keyboard by greatly modifying the structure of the current keyboard. The reason for this is that most of them have stopped the function of the thumb shift at the position of shifting the function keys of the existing keyboard.

The performance of the keyboard shown in FIG. 7 is quite qualitative and subjective, however, what is conceptually expressed here is that while a keyboard has a minimal change from the QWERTY keyboard in order to replace the current QWERTY keyboard, there is a significant performance improvement. It is necessary that conventional keyboards eventually failed because the improvement in performance was relatively small compared to the increased complexity of the keyboard. For convenience, the keyboards newly developed in the present invention are also shown in the conceptual diagram of FIG. 7, but it may be desired that the maximum performance improvement compared to the complexity is directed to the new keyboard.

E. Touch Screen Keyboard

Hangul character input in a portable electronic device such as a mobile phone is rapidly developing from a touch screen keyboard in which the keys are arranged on a screen from a conventional button keyboard in which the keys are physically arranged. In electronic devices using a button keyboard, the change in the arrangement of the keys is considerably limited due to physical constraints, so most mobile phones have a 3x4 array keyboard, whereas in an electronic device using a touch screen keyboard, a screen size that can be used for text input is used. Varies depending on the type of devices such as tablet PCs and smartphones, and the software can be used to freely change the arrangement of keys on the screen, and the text input method can be mixed or immediately changed in various ways. .

In the touch screen keyboard, the inertia of the conventional standard keyboard, which is considered to be of great importance in the design of the computer keyboard, is not a problem at all. Also, in most cases, typing is done using two-handed thumb, one-hand or one-handed forefinger, or several fingers on one hand, rather than using a small amount of text and a ten-finger tactile approach. Various input methods can be used, and the factors that determine the choice can be various restrictions and characteristics such as the user's taste and the size of the keyboard in the corresponding electronic device.

Therefore, in the design of Hangul keyboards on these touch screens, the approach is very different from that of the conventional computer keyboards. However, the common method is that almost all Korean characters input methods and keyboard layouts are based on Hangul's membership. It will be similar to the layout and character input method of the standard computer keyboard used.

The biggest problem to be solved in the present invention is to develop a new sebulsik keyboard to replace the traditional standard bulbeol keyboard that has been used for decades, and to further develop scientific Hangul through Hangul computerization. Hangul keyboard has an inseparable relationship with English keyboard. Currently, it is used as a global keyboard and Qwerty keyboard has many problems and needs improvement. Moreover, in the recent Unicode era, there is an urgent need for a new keyboard that can efficiently input various characters. Therefore, in the present invention, in connection with the development of a new Korean keyboard, the English keyboard is also newly developed as a new input system required in the era of Unicode, thereby attempting to develop a unified and consistent input method for both Korean and English. To this end, we design an efficient keyboard using the keyboard design principles derived from the results of the collective analysis of the developed western and western keyboards. Considering the consistency of the two, we seek to be successful in transitional use and position as the final standard keyboard.

The main goal is to develop a Korean keyboard that is efficient and conforms to the principles of Hangul.

1) It should be a three-stage type keyboard that satisfies the requirements of efficient Hangul computerization and has no waste of key.

2) Ergonomic keyboard with better input efficiency than current standard keyboard.

3) The keyboard should be easy to learn and use.

4) It should be a keyboard that can be easily converted by all citizens using the current standard two-bolt keyboard. This means full compatibility with the current standard keyboard and maximum compatibility.

6) The keyboard should be consistent with the English keyboard. This means that input of numbers, letters, symbols, and symbols except Korean and English characters should be common. In addition, the English keyboard should be able to directly enter a large number of various characters of Unicode in a systematic and intuitive way.

7) The keyboard should be easy to input old Hangul into systematic and unified expansion.

8) The keyboard should be easy to expand into various Korean input such as Hangul notation of English and Chinese, and Chinese input through Hangul.

In the case of the English keyboard, as with the Korean keyboard, the points to be considered in the performance evaluation vary so easily that they are easy to learn and learn, the input speed, the type and number of characters that can be easily input, and the document editing function. In short, it is difficult to evaluate the relative performance of the keyboard. For example, Bboards will be much faster than all other keyboards, but things like standard text editing will be inconsistent with standard keyboards.

A comprehensive analysis of the English keyboards developed so far and the reasons for their failure can be summarized as follows.

1) New keyboard layout and optimized keyboard layout for superior keyboard performance

2) Full compatibility with the basic structure of current keyboard

3) High consistency with current standard keyboard, QWERTY

Although the above requirements seem to conflict with each other and are difficult to satisfy at the same time, it is a necessary condition for a certain keyboard to be positioned as a new keyboard, which is also a problem to be solved in the present invention.

In the present invention, a new quasi-separated keyboard and a new quasi-separated keyboard that satisfy all these requirements have been developed. In the process of developing an efficient Hangul keyboard, a new universal keyboard system (NUniKS) has been developed that can be used in all languages of the world. The entire keyboard system is summarized in Table 4.

In the touch screen keyboard, in addition to the conventional methods such as the sequential input method used in the conventional button keyboard, the same type of battering, and the simultaneous input of a plurality of keys, the touch screen keyboard recognizes that it has moved to another key while pressing one key. A drag input method for inputting a corresponding character may be further developed to increase input efficiency.

Nevertheless, in the touch screen keyboard, it is necessary to input almost 60 letters of Korean middle and middle letters using a limited number of 20 letters. Efficient Hangul input is still difficult because it must be entered. Until now, the touch screen keyboard mainly focused on the method of inputting each letter of Hangeul with the minimum input using the plural key input or the drag input, and the arrangement of the keys to enable it. However, in most cases, it is difficult to use a touch type that uses both ten-finger fingers on a conventional keyboard, and it is difficult to use one finger, two-handed thumb, or multiple fingers on one hand. Since it is necessary to input using two fingers, Hangul character input using a touch screen keyboard is significantly less than the input efficiency of a computer Hangul keyboard.

The biggest issues in the Korean keyboard debate over the last few decades were the advantages and disadvantages of the two- and three-letter keyboards, such as ease of use, ergonomic design, suitability for Hangul structure, and unification between models. The quasi-several partial simultaneous input method and the resulting keyboard arrangement solved all the issues of the keyboard dispute. Among them, the unification between keyboards, which was insisted by Sebulsik keyboard, requires almost no mechanical typewriters, so the unity between computer keyboard, smartphone keyboard and tablet PC keyboard is more demanding. Due to various constraints such as the size of the keyboard allowed, it is impossible to unify the keyboards used in these models, but it is still important to unify the keyboard layout and input method as closely as possible.

In computer keyboard, the letters assigned to the input of Hangul alphabet are arranged in the form of ten-row triplets (10x3), while in the conventional mobile phone button keyboard, they are arranged in the form of three-row divisions (3x4). It was different. Nevertheless, standard keyboard layouts used in computer keyboards were also used in keyboard layouts.

According to the August 2011 Action Plan of the NxM Subcommittee of the Future Korean Keyboard Standardization Forum, the most suitable arrangement for touch screen keyboards on smartphones or tablet PCs will be the intermediate form between the standard double keyboard and the 3x4 array. The number of columns and the number of columns (N x M) will be determined by the second round of early October 2011. In determining the optimal arrangement of the touch screen keyboard, various characteristics such as the area of the touch screen keyboard, various input methods, and ease of rearrangement of the keyboard should be considered, but high coherence with the computer keyboard should be considered.

Based on the standard double keyboard, all the problems of the above-mentioned standard double keyboard are solved, and the new keyboard basic structure that increases the use of the thumb while increasing the consistency with the current standard double keyboard, and the new tactile method and the Hangul syllable accordingly By introducing the partial simultaneous input method, the company aims to develop quasi-separated keyboards that have objective performance superior to that of any keyboard developed so far. In addition, by applying the new keyboard basic structure using the thumb to the English keyboard, the second goal is to secure the unity of the Korean and English keyboards and to develop a new keyboard system suitable for the worldwide Unicode era. Doing.

On the other hand, the touch screen Hangul keyboard used in smartphones or tablet PCs, like the Hangul keyboard for computers, is the key solution for the simultaneous input of Hangul syllables using thumb pads. In consideration of the small keyboard area of portable electronic devices, all basic phonemes of Hangul should be assigned to the basic seats under limited circumstances, but the Hangul syllables will be input at the same time. Design it to be as possible as possible.

A. Perfect compatibility with current standard keyboards

The first solution is to overcome the inertia of the standard keyboard by maintaining maximum compatibility and maximum compatibility with today's double-key / qwerty keyboards. Generally, the standard two-bolt type is criticized as one of the shortcomings, but there are also big advantages. The biggest advantage is that the number of keys is 26, which makes it easy to learn the layout of the keyboard and to use it as a tactile method. The layout of the keyboard considering the frequency of use of Hangul characters is also relatively good, so you can get the optimal keyboard layout by modifying only some of them. Even greater is the fact that more than 99.9% of all citizens who use computers today use this keyboard, although it is the result of unfair governmental repression in the past. It is true.

B. Use of Thumb Fenders

The second solution is to add thumb braces to make wider use of the two-handed thumb, which is currently only used as a blank for both Korean and English keyboards. In current keyboards, you can easily enter characters that are twice the number of regular keys by using plain keys alone or in combination with shifts. In Japanese thumb-shift keyboards, the introduction of two additional keys as thumb shifts has increased the number of characters that can be easily typed to three times the number of ordinary keys. In the present invention, since the three general keys at the bottom of the existing keyboard are extended to the bottom and used as a thumb shift, the number of characters that can be easily input can be greatly increased while maintaining compatibility with the current standard keyboard. Since the middle of the three thumb shifts can easily be used in combination with the left and right keys, three thumb shifts can create five shifted states, resulting in six times the normal number of keys. You can easily enter the corresponding characters. In addition, the new keyboard basic structure of the present invention enables a new tapping method with increased utilization of the thumb. This new tactile technique is much more efficient and ergonomic than the traditional tactile technique except for the simultaneous use of the right thumb, so users of existing keyboards can easily get used to it.

One notable thumb-use keyboard is the Japanese thumb shift keyboard, developed by Fujitsu in Japan in the late 1970s. The number of characters to be entered in Japanese is only 50 basic characters of Hiragana, but much more than that considering the phonetic and semi-traditional characters. In Japanese thumb shift keyboards, place a short key pad instead of a long key pad on a normal keyboard, and add two more thumb shifts, larger and higher than the other pads around it, to determine the number of characters that can be easily entered. Tripled. This Japanese thumb-shift keyboard was a huge success in its own right, but it was not established as a Japanese standard keyboard because of its lack of compatibility with existing standard keyboards due to the use of additional thumb-shift keys. It is analyzed because it did not maximize the Examples of maximizing the use of the thumb can be found in the B-board, Cass Korean-language keyboard, and Sorja-Java Korean shorthand keyboard. These keys are not used for the thumb shift, but all the letters are assigned by using two-handed thumb. Typing is a difference. 50 shows the arrangement of the keys for inputting vowels using the thumb of both hands in the Sori Javanese Korean shorthand keyboard. The reason why the Japanese thumb shift keyboard was not compatible with the Latin / Roman system was that, in the case of English, for example, only about 2.5% of the capital letters in English, the largest use of the shift, I couldn't find it. In fact, thumb shift was not used in English mode of Japanese thumb shift keyboard. However, with the advent of the Unicode era, more symbols and symbols can now be easily entered in an intuitive, organized and systematic way, and the Latin texts that are not in English used in European countries are much easier to use with new tapping methods. It requires a new keyboard base structure that can be entered.

The present invention introduces the thumb shift concept used in Japanese keyboards as the final key for Hangul keyboards in 1978. . In other words, the new quasi-separated keyboard overcomes the inefficiency caused by the excessive use of the shift key, which is why the previous Q2.5 penalty keyboard failed. The thumb key is completely different from the previous shift key in two ways. The use of the key does not contribute to the inefficiency of the keyboard at all, and greatly improves the keyboard input efficiency by allowing balanced simultaneous input. It can be a major factor. First, the thumb cuff is in the reference position of the strong and agile right hand thumb, and second, the delay cuff uses the delayed simultaneous input method of additionally inputting the initial crest while the shift is held down by weak force. In addition, the thumb key can be simultaneously input with the initial key. Therefore, a combination of shift key and general key takes three times as long as typing a single key, whereas typing the thumb key and a single key is the same time as typing only one key. This takes On the other hand, the present invention is distinguished from the thumb-shift keyboard of the Japanese keyboard, since the thumb-shift keyboard of the Japanese keyboard is replaced with a shorter blank key and two new keys are added to the remaining space. On the other hand, in the present invention, since the key corresponding to the general key in the natural position of the thumb of the existing keyboard is designated as the thumb shift, the present invention has perfect compatibility with the existing keyboard.

Thumb clasp in addition to thumb clasp

By introducing punctuation, it is possible to easily enter various symbols and symbols, while also substantially increasing the number of available keys. In the case of English keyboards,

(Inner AltGr) makes it easy to enter Latin / Roman characters that are used in many European countries. Using these three thumb buttons increases the number of characters that can be easily entered in English mode by six times the number of regular keys. The effectiveness of the simultaneous input using the thumb has already been fully demonstrated in existing Korean shorthand keyboards or massage keyboards. In the present invention, it is developed from simple Korean input and integrated with English keyboard to further organize and systemize input efficiency and keyboard. Maximized scalability

C. Partial simultaneous input of Hangul syllables

The third solution is the key to the Hangul keyboard of the present invention. It is the introduction of the Korean syllable partial simultaneous input, which is possible due to the thumb jongjong which can use the characteristics of Korean words and Hangul. In other words, Hangul has a fairly regular consonant and vowels, and since the initials and neutrons are naturally arranged on the left and right in the keyboard, all parts of the Hangul word except for the support can be easily entered at once. Supported letters appear in a ratio of about two letters. In this case, you can additionally enter the support by entering the initial letter corresponding to the support with your left hand and the key with your right thumb. Since the position of the key is on the base of the strongest and most agile right hand thumb, there is no need to move the thumb, so you can mechanically input it without any burden. In addition, blanks appearing at a rate of about 12% in Korean can be entered simultaneously by pressing the blank key with the left thumb when entering the last letter of a word. This Hangul syllable partial simultaneous input automatically solves the problem of double beol type kinetic battering. As a result, the input speed is expected to be improved by 50% ~ 100%, and it will be greatly reduced. This new tactile method can be easily adapted to existing users in a short time because the fingering of all fingers except the right thumb is the same as the previous tactile method.

As a means of concept similar to Hangul syllable partial simultaneous input, the combination of Hangul syllables and computer input characteristics is combined. The standard two-bolt keyboard and the Gong-woo-woo Sebul-type keyboard did not deviate much from the mechanical keyboard. The combined simultaneous input used in the massage keyboard or the traditional Hangul shorthand keyboard applied some of the combined characteristics of Hangul. In the beginning, it is difficult to make the best use of Hangul's combinatorial characteristics by supplying only efficient input of Hangul. In the present invention, in designing the Korean keyboard these days, from the beginning, the application of the Hangul combination characteristics for systematic and unified expansion into the old Hangul and various Hangul Hangul inputs was considered.

In the present invention, Hangul is able to input all initials and final characters as shown in Table 5 by using 14 basic consonants singly or in combination. Here, the basic consonant “ㄱ” is designated by “ㅇ” as a horn. In the combination of "," and "ㄷ", the consonants "쌍" and "ㄸ" are assumed to be entered. Combining the right key is the same principle as entering a double consonant. These horns and braces are collectively referred to as operator keys. Meanwhile, the Korean vowel combination table is shown in Table 6.

In the present invention, only for the Korean input these days horn

The use of is enough. However, if you look closely at Table 5 or Table 6, you can see that you can set more different mechanisms as needed. The requirement for the fitting is that the number of available combinations of the two keys, as shown in Tables 5 and 6, should be convenient and the shape of the hands of each combination should be convenient. In general, the key on each finger's reference key is a good candidate for the function key, and if the finger is a long finger, the upper finger will be a good finger, and if the finger is short, the lower finger will be a good finger. Can be. When expanded to the old Korean keyboard or the keyboard for English or Chinese Hangul, the keyboards were designed from the ground up in consideration of all the situations so that the working mechanisms would operate in an intuitive and systematic way without conflicting with Korean.

D. Scientific and ergonomic keyboard design

The fourth solution is to design more scientific keyboards by using the correct Hangul usage frequency and the aggregation of keyboard theory. When the previous Hangul keyboards were developed, reliable and accurate Hangul usage frequency did not exist or was difficult to be obtained. Early developers developed the keyboard by investigating the Hangul usage frequency by themselves. It can be said that it was used for the part and the frequency of Hangul usage, and it was found that there was a lot of error while handling the data by hand. The keyboard of the present invention can be said to be an ergonomic keyboard designed by properly applying the optimal keyboard theory derived from the analysis of the correct use of Hangul usage frequency and the advantages and disadvantages of the previous keyboards of the East and the West. In addition, it is a scientific keyboard that considers the social science aspect by maximizing the consistency with the standard keyboard in consideration of the resistance of the social mass, which is the biggest reason why the previous keyboards failed. Table 7 shows the Hangul usage frequency in alphabetical order, which is shown in “Analyze Frequency of Hangul Use (Kim Heung-kyu and Kang Beom-mo, Korea University Institute of Ethnic Culture) based on a corpus of about 30 million characters. It is a reorganization by combining them. On the other hand, comparing the frequency of Hangul usage with Korea University based on the 120 million-character data used by the Korea Advanced Institute of Science and Technology, in most cases, the agreement was well within the range of 0.1%. It is confirmed that only about 0.3%.

The frequency of English alphabet used to design the optimal alphabetical arrangement is shown in Table 8, which is a rearrangement of data compiled by Maltron's panel from Brown Corpus' data. In Table 8, the normalization frequency is the data of Maltron's vocabulary and includes the functional keys such as whitespace and almost all signs and symbols. The frequency of financial normalization is the result of renormalization including only English, whitespace and shift.

E. Matched Keyboard and Scalability

In the keyboard proposed in the present invention, the arrangement of characters is not fixed to one. The alphabet layout optimized for the new keyboard basic structure improves the keyboard's performance more than any other keyboard, but it is very different from the existing QWERTY, Dvorak, and Colmack keyboard layouts. There may be difficulties. Therefore, by minimizing the change in the English layout of each of these keyboards, we further implemented arrays that maximized the consistency with the existing keyboards, allowing users to choose from four keyboard layouts for their convenience. These four different keyboards differ only in English, and the inputs and functions of all the other characters are exactly the same. In addition, the new keyboard basic structure not only preserves the shifts, alts, controls, and tabs of the previous keyboard basic structure, but also preserves their functions and operations in the same way. Discomfort during the period of adaptation was minimized. In the same way, Hangul array proposes final and matched arrays for user convenience and easy conversion.

In addition, the scroll keyboard according to the present invention is not limited to easy input of characters and general codes or symbols used in general sentences. 172 symbols on each major board by organizing systematically and systematically arranging symbols that are frequently used in each field or application of all disciplines such as mathematics, physics, logic, and international speech symbol (IPA) in 40 general keys. You can assign them to each of these characters, either by single key or by thumb

,

, or

Can be used easily with If there are more than 172 symbols commonly used in one major field, it is possible to design a keyboard arrangement subdivided into Mathematics Edition I and Mathematics Edition II. Each major keyboard is operated by a predetermined shortcut key, and a total of 172 character arrays can also be easily found on an on-screen keyboard using a predetermined shortcut key (eg Ctrl_IS) and easily entered with a thumb shift.

F. touch screen keyboard

Maximizes the efficiency of Hangul character input in these devices by designing a keyboard array that can be used for smartphones or tablet PCs by distinguishing the initials and the final characters by using the bellows using the characteristics of Hangul. . Since almost all smartphone or tablet PC users have experience using computer keyboards, it is as close as possible to computer keyboards and the input method is as uniform as possible, rather than designed to maximize input efficiency only within the portable device itself. It is important. In the present invention, an input method and a keyboard that maximize the possibility of simultaneous input of semi-separated keyboards and Hangul syllable partial simultaneous input in computer keyboards in consideration of the general conditions such as the size and input method of the keyboard allowed in a smartphone or tablet PC. Develop an array.

The optimal number and number of keyboards for smartphones or tablet PCs using the touch screen can be easily determined from the current status of the keyboard arrays used in currently available smartphones and tablet PCs and the characteristics of Hangul.

The conventional Korean keyboard for smartphones has ten rows because it uses almost the standard double layout of computer keyboards. In this structure, each typography is too small, which causes a lot of typos. As a solution to this, around the Korean language day of 2010, Google developed and announced the Google single vowel keyboard. This keyboard has an array of eight rows and three columns, and there is no key assigned to the basic vowels ㅑ, ㅕ, ㅛ, ㅠ. The number of strokes for the game is slightly increased, but it is estimated that it keeps a lot of standard doubles while greatly reducing typos. Therefore, a smartphone with eight rows can be considered as a typographical improvement, and the number of columns can be reduced to seven or fewer to further reduce the error by increasing the size of the key.

Another thing to think about in order to determine the proper number of hot water is the characteristics of Hangul. Hangul has 24 basic phonemes and consonants are placed on the left side of the keyboard and the vowels are placed on the right side of the keyboard for efficient input of positive and negative batters. It is preferable. From this, it is possible to draw a natural conclusion that the Hangul keyboard to be used in a smartphone or tablet PC using a touch screen should be an 8 x 3 array or a 6 x 4 array.

You may decide whether you'd like the 8 x 3 array or the 6 x 4 array better than the whole, but you don't have to. Since the touch screen keyboard can change the keyboard layout that the user wants immediately, it is possible to implement both arrangements so that users can select and use the same device according to the type of smartphone or tablet PC and the same device. When designing the two arrays, simply increase the unity so that they are as similar as possible to each other and similar to the standard double keyboard layout for computers. In addition to the similarity of keyboard layouts, efficient Hangul input methods such as quasi-separated Hangul syllable partial simultaneous input using a final delimiter will be unified.

A. Superiority of Hangul Keyboard of the Present Invention

The number of inputs required for sequential input of standard double punishment, sequential input of vacant dominant punishment, simultaneous input of massage secular punishment, and partial simultaneous input of new punishment punishment is compared with the full text of the National Charter of Education except for the punctuation, as shown in Table 9. It was.

Comparison of the number of strokes required for the input of the National Education Charter Standard Vacancy Massage Jun Joon Seol Jun Joon Seol Required stroke 1151 strokes 1131 strokes 393 strokes 574 strokes 705 strokes ratio 100% 98.3% 34.1% 49.9% 61.3% Relative speed 100% 101.7% 293.3% 200.4% 163.1% Remarks Blank input Blank input Bundang average record 500-600? 600-800? 1400? ? ?

In Table 9, the semi-separated space input separately refers to the input of two inputs, separating the support and the space at the end of the word. This is to prevent typos due to the possibility of pressing the key underneath the thumb when using the thumb on the standard keyboard. Pressing a key alone or pressing a blank key together acts as the same key, so you'll get a much more natural typing, even if you get more batters. Encoders work the same way.

The relative speeds shown in Table 9 are the results of a simple comparison of the required strokes. The biggest variable that determines the typing speed is the required stroke. This can be confirmed consistently through the simultaneous input keyboard of English syllables, two Hangul shorthand keyboards, two beoldong battery keyboards, and massage fetish keyboards. However, the reduction in the number of strokes required does not lead to the speed of battering. The cause of the slowdown is the lack of stitching effect, which is the maximum in both hand batters, and the increase in time required due to the complexity of the hand shape of each combination. This can be said to be a complex action to stay at about 1400 strokes rather than 1500-1800, which is three times the minute speed of massage keyboards. In the case of semi-separation, the speed of the combined stroke is much simpler than in the case of se-seul. The typing record for each keyboard in the table is neither accurate nor quite arbitrary. In the case of double keyboards, more than 1000 strokes per minute may be claimed in a short time.

From the results in Table 9, the partial simultaneous input of the standard tax is half of the number of strokes required in the standard two sequential inputs, so an increase in input speed of nearly twice can be expected. On the other hand, the number of strokes required for the partial simultaneous input of semi-three sets is 146.4% of the total simultaneous input of three sets, which is 46.4% larger. However, it is difficult to say that the three simultaneous simultaneous inputs are about 46% faster than the partial simultaneous input of the new standard, since the former is much more difficult than the latter. The 393 strokes, 69% of the 574 strokes of the semi-threes, can be thought of in common with the average of three strokes. It's an easy combination. In the case of partial simultaneous input, 99.852% except for 제외한 (0.122%) and ㅞ (0.026%) can be inputted with up to two keys at the same time. All combinations of two keys on each hand are designed to be comfortable. Although it is difficult to predict, the full simultaneous input may be about 10-30% faster compared to the case of full-blown typing, but the partial simultaneous input is expected to be faster in the case of loans before the full ripening stage. .

The input speed of the keyboard is also important, but the difficulty of learning how to use the keyboard is also very important. Moreover, to be used as a standard keyboard, everyone should be able to learn and learn easily. Partial simultaneous input of the present invention to learn how to use a keyboard may be much easier than sequential input of a standard double type. The reason for this is that the standard double keyboard has the same number of battering problems and shift use problems as pointed out above, whereas the partial simultaneous input of the present invention is only 99.9% of cases in which the left hand and the right hand each have only one or two keys. This is because the keys are arranged so that the shape of each hand is very natural. On the other hand, the full simultaneous input of massage type keyboard is much more difficult to learn and learn than the partial simultaneous input of the new quasi-sebul type, for the following reasons.

1) Since the massage keyboard inputs the vowels, ㅋ, ㅌ, as a combination of two keys, this means that in syllables containing vowels, the number of keys input simultaneously with the left hand, even if the support is not considered, More than one.

2) In the massage keyboard, the maximum number of keys handled by the left hand is four and the maximum number of keys handled by the right hand is five, one or two more than the three and three in the case of the new semi-serious type. As the number increases, hand gestures become much more complex and difficult.

3) In the arrangement of semi-separated vowels, the “ㅣ” key, which is combined with almost all vowels, is placed on the ring finger, and has a natural hand shape corresponding to all combinations of laps and triples. In the case of the massage keyboard where the “ㅣ” key is placed at the middle of the middle, the input of “ㅟ” and “ㅢ” is inconvenient, despite the complexity of additionally inputting the bottom support. In the case of “ㅟ”, except for the middle finger, it is difficult to press the middle finger and the body at the same time. In the semi-separated consonants, the combination of the horns, which requires the input of two keys at the same time, is also placed on the index finger, so all the combinations of the consonants except “ㅆ” have a natural hand shape. The input of “ㅆ” is also exceptionally duplicated as “b + ㅇ → ㅆ”, so it has a natural hand shape. Almost all of the overlapped combinations have a comfortable hand shape, and the uncomfortable hand shape has an unusual overlap with “ㄹ + ㅈ → ㄼ”.

4) Complete simultaneous input of massage keyboard should be learned so that the hand shape is doubled to every body. The cumulative percentages of the Hangul characters are 95%, 99%, and 99.5%, respectively, of 446, 808, and 1287 characters. Therefore, in order to properly master the massage keyboard, you need to learn more than a thousand hand shapes, but since fingering is not fixed, there is a difficulty to find and study a comfortable hand shape for each letter, and then practice it. On the other hand, in the partial simultaneous input, the left hand has 14 hand initials, 14 double initial consonants, 5 double consonants, and 11 overlapping combinations. There are a total of 22 hands, 9, 2 triples, and 1 key. Therefore, in order to input all the letters of Hangul as one stroke if there is no support, and two strokes if there is a support, you only need to learn 52 hands with 30 left and 22 right hands, 25 of which are single. It is a key. The relationship between full simultaneous input and partial concurrent input is similar to that of Korean complete code system and combined code system. Of course, the standard double sequential input can input all syllables with a total of 33 hands, but in this case, the number of strokes is twice that of the partial simultaneous input, but there is no significant difference in the number or complexity of the hands.

5) The complete simultaneous hitting method of massage type keyboard is difficult to use properly with general keyboard, not enki rollover, but semi-separated partial simultaneous input can be used with almost all general keyboards.

Two implementations of the present invention, the final type and the matched Hangul keyboards, are superior to the previously developed keyboards by explaining various performance indices shown in Tables 10 and 11. These data apply the Hangul alphabet usage frequency of Table 7, but it is the result of considering all the keys needed to input Hangul sentences except punctuation, that is, the use frequency of shift, closing key, and blank key. It is more rational than the method used for evaluating only the element. Considering the input method of the keyboard from the Hangul phoneme frequency, each key is calculated before and after the correction, and normalized so that the sum of the letter ratios after the correction is 100%. For example, in the case of the most frequent “ㅏ” phoneme in vowels, the Hangul font rate is 8.8793%, but the pre-correction letter rate is 9.63% in the standard double, 9.63% in the vacant cow, and 11.55% in the massage mass. In addition, the post-correction rate is 11.55% in the new semi-degree, 8.11% in the standard double, 8.22% in the Seong-beop-seung ceremony, 9.26% in the massage parlor, and 8.18% in the semi-separation. As for the usage rate of white space, the pre-correction writing ratio was set to 13.64% so that the space ratio after correction was only 12% considering only Hangul alphabet and space, and the same correction rate was applied to all keyboards. The resulting post-correction void rate was 11.49% for standard doubles, 11.65% for vacant soldiers, 10.94% for massage parlors, and 9.67% for new quarters.

Table 10 shows the finger usage of each keyboard, where L and R represent the left and right hand, respectively, and the numbers 1 through 5 represent the thumb, index finger, middle finger, ring finger, and hand. For example, L2 represents the left hand index finger and R4 represents the right hand ring finger. In the case of index finger, L2-1 and L2-2, etc., were used to distinguish the column of reference key and the column to extend inwardly. The preferred distribution of finger utilization should be higher from the base to the inside of the keyboard from the base to the index finger, but the utilization of the keys that the index finger should extend into the inside of the keyboard should be low. In order to visually easily show the distribution of these finger utilizations shown in Table 10, the standard double in FIG. 8, the double in North Korea in FIG. 9, the third in empty in FIG. 10, the third in FIG. The new quasi-three matched type shows that the new quasi-three keyboard has an overall balanced finger usage rate.

Table 11 shows the home row ratio (HRR), home key ratio (HKR), left hand side (LHS), right hand side (RHS), and index index for each keyboard. (IFSR: Index Finger Stretch Ratio), shift utilization, and utilization of each stage are compared. Of note, the baseline use rate refers to the use of the keys that were originally located at the middle of the keyboard, including the blanks using the thumb or the closing key in the semi-separation. In the case of the previous keyboard, the actual use of the blank key often uses only the left hand or the right hand depending on the user, but here, the left hand and the right hand are divided by half and inputted. The higher the reference stage utilization rate and the reference key utilization rate are, the better the detection extension rate, the shift rate, and the lowermost utilization rate are. In addition, it becomes more difficult to input in the order of the reference stage, the top, and the bottom, but in the case of the massage keyboard, the six keys in the middle are entered with the thumb. As shown in Table 11, in the case of the semi-separated final type, the reference stage utilization rate and the standard bracket utilization rate are overwhelmingly high compared to other keyboards by 13 to 24% and 16 to 25%, and the use of the lower end is overwhelmingly low at 1.6%. . Overall, all other performance indices, except for left- and right-handed use ratios, show that the final semi-final type is superior. The matched semi-sections are slightly less than the final ones, but still differ significantly for other keyboards. The right hand and left hand use ratio is about 10% higher than the right hand use ratio, except for the massage keyboard, all other keyboards use the left hand usage ratio much higher than the difference of 10.8% ~ 15.8%. Is only 6.8%, which is a big improvement.

B. Superiority of English Keyboard of the Present Invention

The present invention enables a more efficient new palpation method that increases the use of the thumb, and the number of characters that can be easily input increases from twice the number of general keys to six times. It has the most efficient keyboard layout with excellent characteristics such as rolling average. Yet the keyboard of the present invention is fully compatible with existing standard keyboards, and also has high compatibility with existing major keyboards such as QWERTY, Dvorak, and Colmack. In addition, by utilizing the on-screen keyboard, various large letters, symbols or symbols can be directly and intuitively inputted through the keyboard while maintaining a simple keyboard layout. Various characters or signs that can be easily entered by the present invention will serve as a guide for an extended set of standard codes / symbols that all fonts are recommended to have. Conventional three-key rollover keyboards allow you to enter most major letters or symbols at the same time using the thumb function.

Performance of the previous four English keyboards and four implementations of the English keyboard developed in the present invention (Nunix-Q, Nunix-D, Nunix-C, Nunix-S) are shown in Table 12, Table 13, and Table 14. The data in Table 12 and Table 13 are the results of using the alphabetic frequency in Table 8, the unit is percentage, and the data in Table 14 are the English graphs in Dvorak's “Typewriting Behavior”. As a result of using the analysis, the generic numbers in the table represent the graph frequency in ten thousand (10,000) units.

In Table 12, L and R represent left and right hands, respectively, and the numbers 1 to 5 following each represent thumb, index finger, middle finger, ring finger, and hand. For example, L2 represents a left hand index finger and R4 represents a right hand ring finger. In the case of index finger, L2-1 and L2-2, etc., were used to distinguish the column of reference key and the column to extend inwardly. The preferred distribution of finger utilization should be higher from the base to the inside of the keyboard, but the detection extension rate should be low. In addition, weak or weak agile possession or ring finger is assigned to the letter at the top or bottom of the letter with a particularly low frequency ?? To visually easily show the distribution of these finger utilizations shown in Table 12, Qwerty in FIG. 14, Dvorak in FIG. 15, Colmack in FIG. 16, Maltron in FIG. 17, Nunix-Q in FIG. 18, Nunix in FIG. D, FIG. 20 shows the Nunix-C, and FIG. 21 shows the Nunix-S arrays, respectively.

In Table 12 and FIGS. 14 to 17, it can be noted that in many cases of conventional keyboards, the usage rate of the base is too high, rather than the usage of the ring finger. This is due to two factors. The first reason is that the Dvorak keyboard, which has a large weight in English or Japanese keyboard design, increases the sharing ratio in the order of possession, ring finger, middle finger, and index finger, but uses each finger relatively balanced. Because The results of Rimer's experiments, which Dvorak used to determine the proper allocation of fingers, did not reflect the strength or agility of each finger, comparing only the simple tapping rate of each finger. In other words, designing the keyboard according to the ratio may result in an over-normalized distribution of finger utilization. In the case of the Maltron keyboard that stands for ergonomic keyboard, it was designed based on the design principle that reflecting the results of reamer's experiment is negative and using all fingers evenly is most desirable. Compared to Dvorak and many Japanese keyboards that use each finger relatively evenly, Hangul keyboards generally reduce the use of possession and ring finger and increase the use of index finger. Comparing the results of the Dvorak keyboard of FIG. 15 and the vacant cow keyboard of FIG. 10, this difference is clearly contrasted. These two keyboards are known to be much easier and easier to type than other keyboards, Qwerty keyboard for Dvorak, and standard two keyboard for Gongwoowoo's three. This conflicting layout design principle is difficult to judge which is right and very difficult to prove experimentally. Therefore, the keyboard designer considers the strength and agility of each finger in combination with other keyboard design principles. It can only be determined by an accidental experiment. In the present invention, by taking advantage of these two methods, that is, increasing the utilization rate in the order of possession, ring finger, middle finger, and index fingertips is much larger than the increase rate in the results of reamer experiment, but avoiding assigning too much to the index finger. .

The second reason why the use rate of your handset is too high in many cases of previous keyboards is that the design and analysis of most keyboards, including Dvorak keyboards, have not considered the use of shifts in assigning finger usage. Shift is used for uppercase letters, which is about 2.4% overall, and additional burden of about 1.2% for left and right handholds, and the actual burden will be much greater because of the delayed overlapping method, so ignore the finger share ratio. Assignment is a big mistake in the keyboard layout design principle. In Figs. 18 to 21, the usage rate of the left hand thumb L1 of the nunic keyboards appears to be too high, but it is not a big problem since it is a blank input. In consideration of this, it can be seen that the Nunix-S array of FIG. 21 has the most balanced finger utilization distribution among FIGS. 14 to 21.

When inputting English letters through the keyboard, each key is input sequentially. Combination of keys and fingers corresponding to each successive input graph is important. Ultimately, this combination leads to Home Row Ratio (HRR), Home Key Ratio (HKR), Successive Same Hand (SSH), Successive Same Finger (SSF), and Short Transition. (row transition), column transition, inward rolling (IR), outward rolling (OR), and detection elongation are determined.These performance indexes determine the performance of English keyboards. It is important.

Table 13 shows the comparison between the reference stage utilization, the reference utilization, the left hand side (LHS), the right hand side (RHS), the index elongation rate, the shift utilization rate, and the usage rate for each stage. The higher the reference stage utilization rate and the reference frame utilization rate are, the lower the detection extension rate and the lower utilization rate are, and the right hand use rate is about 10% higher than the left hand use rate. In Table 13, the Nunix-S array is about 5% and 4% higher than the Dvorak array, the detection elongation is about 2% lower, and the bottom utilization is about 3% lower than the Dvorak array. You can see that. The left hand usage of the Nunix-S array is very high in the table, because the left hand contains a white key input, which accounts for about 17.4%. However, since the input of the blank is done with the left thumb naturally placed in the reference position, the actual left / right hand sharing ratio is not as bad as the apparent value.

Table 14 shows a comparison of the single transition rate, inward batting average, outgoing batting average, battering battering, and battering battering. In general, positive batters are more efficient than equal batters, inwardly moving inwards from the outside of the keyboard are more efficient than outward batters in the opposite direction, and the stage transition between the top and middle breaks is greater than the stage transition between the middle and bottom ends. Although more efficient, short transitions between the top and bottom are known to be the most difficult. The dynamic batting rate shown in Table 14 requires further explanation. Winter battering is a type that uses the same finger in succession to input a graph, it is generally known that the input speed is slow compared to input using a positive shift or two different fingers. A special case of winter battering is the successive same key (SSK), in which the same key is entered consecutively. Previously, copper bars were not included in the comparative analysis of the battered battering rate in keyboard performance, which is not reasonable and tends to be misleading. For example, compared to Qwerty keyboard, the batting average improved about 3.4 times for Dvorak keyboard and about 21 times for Maltron keyboard. The actual improvement in winter batting average rate is only 1.7x and 2.3x, respectively.

Here, I would like to explain the validity of including copper battering in winter battering. In FIG. 22, when inputting a combination of two arbitrary keys in a QWERTY keyboard, the input speed relative to each graph is shown as the number of input words per minute. In FIG. 22, the input speed is generally lower than that of a trill or a rock using two fingers. Only the special case of the trill “l; Is a combination of ring finger and possession and is the exception. In addition, the input speed of the special case of copper battered battered yeonjeyeon yeonji "jj", although slightly better than the other yeonji batter "um" or "jm", it is much worse than a trill or rock, so the battered battered battered battered battered battered It can be seen that it is appropriate to include in the. In Table 14, it can be seen that the Nunix-S arrangement of the present invention has a much better copper batting rate than all other keyboards from the result of including the copper batting in the winter batting. We can also see that even without the double key, the Nunix-S array has a lower sieving rate than all other keyboards except the Maltron keyboard.

C. Superiority of the Invention Applied to a Touch Screen Keyboard

When the Korean syllable partial simultaneous input method using the thumb of both hands is applied to the touch screen keyboard of the smartphone through the keyboard arrangement of the thumb terminal identifier and the left parent, more than 80% of the Korean syllable partial simultaneous input rate is possible. The input efficiency can be greatly improved. According to DualLog Co., Ltd., which developed the Hangul input method for touch screen keyboards for smartphones, the Korean input numbers of general mobile phone keyboards are 53% and 35, respectively, by representative companies, rather than the input numbers on standard double keyboards. Compared with% and 32% more, DualLog's Hansegle claims it's a relatively fast input because it only adds 17% more strokes. However, more than 80% of the Hangul syllable partial simultaneous input is expected to be 70% less than the number of strokes required in the standard pair, and thus the input efficiency is superior to other methods.

Another advantage of the touch screen Hangul keyboard according to the present invention is that the layout of the keyboard is similar to the computer Hangul keyboard.

51. The Table of Contents of the Patent

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention may easily add other embodiments by addition, change, deletion, addition, etc. within the scope of the same idea. It may be suggested, but this will also fall within the scope of the spirit of the present invention.

The Nunix-Q / semi-separated final type arrangement, which is the arrangement of the new English / Korean keyboard developed in the present invention, is shown in FIG. 23. The Nunix-Q array is an arrangement of the English keyboard developed in the present invention. It's almost like a QWERTY array. First, the overall description will be made with reference to FIG. 23, and a detailed description will be given of the Korean and English keyboards and the old Korean keyboard which is an extension of the present invention.

The basic structure of the keyboard shown in FIG. 23 is different from the basic structure of the 101-key standard keyboard of FIG. 1 or 2, and the short space 127 and the "B" (45) and "N" (46) of the QWERTY keyboard. , The letters corresponding to "M" (47). That is, the short blanks 127S use the left thumb, and the three keys 45E, 46E, 47E extending to the bottom are the thumb acting keys used as the right thumb. In English

,

In Hangul keyboard

,

These thumb functionalities, denoted by, increase the number of characters that can be easily entered directly through the keyboard in an organized and systematic way by using simultaneous combinations with other general keys. Also the middle thumb

46E is the left and right

With 45E

It can be easily combined with (47E) to increase the number of characters that can be easily entered. Due to these thumb actuation keys, almost all characters can be easily inputted by the touch typing method using only the keys in the convenience pushing

type areas

151 and 152. On the other hand, all the functionalities such as shift, control, alt, tab, and the like used in the 101-key standard keyboard are preserved in the present invention of FIG. 23 and the usage thereof remains unchanged. In addition, since there is no change in the arrangement of numbers and symbols assigned to the lower digit and the upper digit of the uppermost end of the keyboard 115, it has high consistency with the existing keyboard.

In Fig. 23, the general keys used for inputting the characters except the function keys and the function keys are mostly four letters engraved on each corner of the key face, and some keys on the right side of the keyboard are used. There is an additional letter in the middle of the face, and all five letters are engraved. As an example, an enlargement of the “7” key 17 is shown in FIG. 24, and the marking convention of the keyboard figures shown in the present invention will be described using this. Unless otherwise noted, especially when three or more letters are engraved on most key faces, the letters engraved on the bottom of each key face (156) indicate the characters entered when the key is pressed alone. Mark, and the letters engraved in the upper left (155) are shifted or

Indicates a character that is entered when used with and the letter engraved in the lower right (157)

When used with, it displays the characters to be entered, and the characters engraved in the upper right (158), in English mode, the key is Altgial or

Indicates the character entered when used with. However, the letters assigned by the English characters in the lower left (156) to display the Hangul alphabet assigned in the Hangul mode instead of the corresponding lowercase letters is the same as the convention used for all Korean English keyboards currently in use. On the other hand, the characters engraved in the center of the key surface 159 of the keys on the right side of the keyboard represent characters input when the keyboard is used in the numeric keypad mode. Numeric mode uses shift in Korean keyboard and function (Fn, 128) in English keyboard. Numeral mode may not be applied in English mode because function is not present in 101-key standard keyboard but exists only in? have.

On the right side of the keyboard

Inner Backspace (2B) is an easy way to correct a typo by overriding the lock in the convenience prompting batter area. The lock is also located at the bottom right of the keyboard.

The key 4A is used to input other characters as well as to duplicate the numbers and symbols placed at the top so that they can be entered using the keys at the top and the top of the convenience prompt type area. A function key that increases the number of characters that can be input, the use of which is described again below with reference to FIGS. 45 and 46. Meanwhile, symbols or symbols assigned to the three

keys

2C, 2D, and 3B on the right side of the keyboard

These keys are preliminary adjutants that can be easily converted to the appropriate adjutants as needed, since they are either dual implementations or low importance symbols that can be easily entered in conjunction with.

Three Thumb Function Keys

Has the same function in English mode and Korean mode.

Wow

Its function is completely different between the two modes.

And first lock

As otherwise indicated. Keys with the same function in both Korean and English modes

Is used to enter common symbols or symbols in combination with the regular key. In English mode

(Inner Shift) has almost the same function as shift, so when you combine it with a regular key, you enter the corresponding upper character.

I

When used in conjunction with, more extended characters are entered, which can be easily entered by tactile method in the position of the reference position of the thumb of the right hand.

(Inner AltGr) is very similar to Altzial, and is used to enter Roman / Latin characters other than English, which are commonly used in European countries, in combination with regular keys.

Wow

As the name suggests, each function is almost the same as the function of shift and altzial, but it is located close to the reference position of the right hand's thumb and uses simultaneous input or sequential input instead of chronic delay simultaneous input. Let's do it. Instead of these mechanisms, shift or altzial can be used in the same way as used previously, thus maintaining consistency with previous keyboards and reducing the inconvenience of transient use. For example, to enter an uppercase A

+ A,

You can use any of the three methods -A and Shift_A, but the most convenient and preferred method is the simultaneous input method.

+ A.

In Hangul mode, the general key on the left side of the keyboard inputs the Korean initials, and the general key on the right side inputs the neutrons.

(46E) is used as a final key. Therefore, the general key on the left side for inputting the initials

When entered simultaneously with (46E), the appropriate seed is entered. However, even in Korean mode

Tooth lock

When used with (45E), the same as in English mode

Will function as. Third thumb function

(47E) is also used differently in Hangul mode, but it is not used in modern Hangul that follows the current Hangul spelling, but is used as the first goggle in old Korean keyboards.

I put it together.

As shown in FIG. 23, when four or five letters are engraved on each face of the general key, the keyboard may appear more complicated than necessary. As described in more detail below, the letters engraved in the upper right corner of each key (158)

In many cases, engraved in the lower right (157)

It has a significant association with the code characters associated with and can be intuitively inferred from the code character. In addition, most of the numeric keypad arrangements engraved in the center 159 of each writing surface are arranged in a regular order. Characters that cannot be easily inferred from engraved characters or that are not regularly arranged are not used so much that you can see the keyboard immediately by using shortcut keys if necessary, so there is no need to inscribe on each face separately. Accordingly, the Nunix-Q / ShunJun Sebul type final keyboard of FIG. 23 may be embodied in a form in which three letters are engraved in general keys as shown in FIG. 25. This applies in the same way to the keyboard when the non-Hangul character system is the main language. For example, in the case of a Japanese keyboard, in Fig. 23 or 25, everything related to English / Roman is the same and Hangul is appropriately arranged in the lower left corner where Hangul is written, instead of Hangul. Instead of iron, you can assign a working iron that suits the characteristics of the Japanese language. On the other hand, in the case of languages of the Roman alphabet system, including English, as shown in FIG.

It is more desirable to have the letters associated with them inscribed. However, when not using a lot of Latin / Roman letters, a simpler face may be preferable as shown in FIG. 27. By doing so, the keyboard developed in the present invention can be a scrollable keyboard suitable for the Unicode era, regardless of whether it is a Roman or non-Roman character system.

The present invention is most preferably implemented on a keyboard equipped with short blanks 127S and extended clamps 45E, 46E, 47E, as shown in Figs. 23 and 25, but the conventional 101-key standard keyboard Since it can be written as in FIG. 28, there is no compatibility problem with conventional standard keyboards. In the case of the massage type keyboard, six keys at the bottom center are input using the left thumb and the right hand thumb, and in the case of the humorous Chinese input keyboard, all 10 keys at the bottom are used for the thumb, whereas the thumb of the present invention is used. Is not only limited to the three keys at the bottom center, but it is expected that there will be no problem because the combination is extremely simple in combination with most other general keys. Nevertheless, since the keys 45, 46, 47 using these thumbs are adjacent to the blanks 127, it will be inconvenient to enter the thumbs up slightly when hitting these functions. In order to reduce such interference with the blank, a slotted blank 127C may be used as shown in FIG. The slotted blanks enable the production of a keyboard suitable for partial simultaneous input using the thumb axle proposed in the present invention with minimal changes in the production of conventional keyboards. Fig. 30 shows the three-dimensional appearance of the grooved fine iron. Meanwhile, as shown in FIG. 31, the keyboard of the present invention has an arbitrary distance between the left side 181 and the right side 182 of the keyboard, s, and each column is aligned at right angles without being arranged as opposed to the existing keyboard. It can also be arranged. Now, the Korean keyboard and the English keyboard will be described in more detail.

A. Hangul Keyboard

32 shows the arrangement of the new quasi-three final template. The first 10 keys at the top are assigned ㅂ, ㅈ, ㄷ, ㅎ, ㅁ, ㅛ, ㅕ, TT, ㅠ, ㅑ, and the first 10 keys at the baseline are respectively ㄹ, ㄱ, ㄴ, ㅇ, ㅅ, Assign ㅗ, ㅓ, ㅏ, ㅣ, ㅡ, and in the first 10 keys at the bottom, ㅋ, ㅌ, ㅊ, ㅁ,

,

, (ㅙ), (ㅞ),

Was assigned. If you use a key assigned to the initial of the left part of the keyboard alone, the initial is entered and the final key

If you use it like this, the corresponding neutron is input, but the key assigned to the neutron in the right side of the keyboard is

If used as in the same manner as when used alone, the corresponding neutron is input. The lowercase letters and uppercase letters of the English keyboard and the? Array of FIG. 36 are assigned to a font that is not assigned to a Korean letter, and when the font is used alone, the corresponding lowercase letter is input.

Same key as

When used with, the upper digit is input to ensure unity between Korean and English modes. Also, key

And the lock

The arrangement related to is identical to that in the English mode shown in Figs. 40, 42, 45, and 46, so that the unity between the Korean and English modes is maximized.

,

Wow

A more detailed description is given below in the English keyboard realization section. First lock

Nowadays, it is not used at all in Korean input, so you can use it as other action keys such as boilerplate shortcuts if necessary, but it is used to input old Korean as the first key in old Hangul mode, and the first point in the Hangul Hangul mode. It will be used to input consonants. The five keys on the right side of the keyboard (2C, 2D, 3B, 48, 49) are preliminary functional keys that can be converted to boilerplate shortcuts as necessary.

FIG. 33 shows a new quasi-separated matched array, which is identical in all respects to the final array except that four Hangul consonants differ in the arrangement of four consonants (a, ㅅ, ㅁ, ㅎ). In each array, the current standard double-array array and the other keys are 11 in final form and 7 in matched form, respectively, and are indicated by shading in FIGS. 32 and 33, respectively. The arrangement is designed mainly, and the matching arrangement of FIG. 33 emphasizes the consistency with the current standard double type keyboard and minimizes changes therefrom. The arrangement of the matched semi-separated type keyboards differs from the current standard two-set type by only three in the consonant part (d, b, ㅇ) and four in the vowel part (ㅑ, TT, ㅠ, ㅡ). Therefore, those who are already familiar with the current standard two-stage formula can be easily changed to matched semi-semi-type, and the second transition from matched to final can be easily done. If you are new to Hangul keyboard or you are still a beginner, you can start with the final semi-separated keyboard. The two keys (48, 49) marked “(ㅙ)” and “(ㅞ)” at the bottom right of the keyboard are redundant implementations of ㅙ and 되는, which are entered in combination. It is a temporary measure to improve the possibility of partial simultaneous input on a general keyboard which does not become.

In the arrangement of FIGS. 32 and 33, there are keys outlined in the Hangul alphabet, which input the phoneme by itself, but when used in combination with other keys, it is used as a kind of operation key.

Since it is not used as a functioning key in Korean inputs these days, it is possible to ignore this outline notation for Korean inputs. Horn

Is used to input the old phonetic letters. The usage is summarized in Table 15. For reference, the notation in English in parentheses in Table 15 means not the English keyboard layout of the present invention but a keyboard layout of the qualitative keyboard. In Table 15, the input of 은 is “ㅅ +

The combination of ”is a bit inconvenient to type at the same time.

You can see that it is a redundant implementation so that it can be easily entered. Almost all of the lap combinations had a comfortable hand shape, and the uncomfortable hand shape was exceptionally duplicated with “ㄹ + ㅈ → ㄼ”. Similarly, in a matched quasi-separated keyboard, the input of ㄲ is a +

And d +

Redundant implementation On the other hand, the vowels of k, k, k and k are assigned to the keys at the bottom, but if possible, they can be entered in combination with the k, a, c, k keys and the keys on the right, respectively. Hangul can also be entered with the easy top and middle keys. Therefore, in the three-stage ceremony,

+ D + ㅌ → ㄾ ”

It would be more convenient to type in “+ ㄹ + ㄷ + ㄱ → ㄾ”.

There are two ways to input a seed by using a seed key: the injection force method is to input the seed key and the corresponding initial key simultaneously, and the secondary method is to input them sequentially. Similar horn

You can use both (34) to input the rhythm, or to enter the vowels or vowels in a combination, using both simultaneous and sequential inputs.

+ A + ㅅ ”or sequentially

+ ㄱ-

You can also type + ”.

In Korean, there is no case sensitivity, so the shift 123 is not used as in English. Similar to shift

The functional key is used as the final key in Hangul, but it is not necessary to use the final key until shift. Accordingly, FIG. 34 shows that a numeric pad 168 is implemented in the touch type by using a shift 123 that is not otherwise used in the Hangul mode. One way to improve a bit more In English mode, you can't use these numbers because Shift is used to type uppercase letters, but in modern computer keyboards, especially notebook keyboards, the function (Fn) key ( In addition, 128) is additionally provided, and in many cases, the arrangement of the number plate is slightly different from that in FIG. In such a keyboard in which a function is added in hardware, if the numeral plate of FIG. 34 is implemented using the function 128 instead of the shift, a uniform numeric plate may be used in the Korean mode and the English mode. On the other hand, in case of keyboard with function ?? While pressing the shift 123 and the function 128 together, by pressing the keys of the keyboard right part 169 of FIG. 35, a command about moving the cursor may be input to the computer.

B. Expansion to the Old Korean Keyboard

32 and 33 include all the information necessary to use the old Hangul mode. Nowadays it is used to input old Hangul using the Korean keyboard. That is, in the old Hangul mode, the first goggle

(47E) inputs old letters ㆁ, copious letters, political sounds, etc.

(23) is the third letter to enter the old letters ㅿ and ㆆ

24, to enter the chief, vowel lock

(38) is used to enter the neutral pad and the bottom ah. In the matched arrangement of FIG. 33 the third lock

Instead of

Except for (31), there is no change in the position of the irons. Table 16 summarizes the use of these padlocks, and there is a significant association between the padlocks and the typed characters, so you can easily enter old Hangul texts without too much memory burden.

Nowadays, the injection speed method is the syllable partial simultaneous input because the input speed is the highest priority in Hangeul, but the sequential input is the injection power method because the priority is given to the input of Gore characters and syllable syllable syllables. However, even when entering a document containing a lot of old Hangul, many parts of the sentence can be entered only in Korean these days, at this time, write a partial simultaneous input in the recent Hangul mode, and immediately only in the part corresponding to the old Hangul Switch to Hangul mode and input as sequential input. In the old Korean keyboard, which was developed in the past, for example, Kim Seong-sik's Sebul-style old Korean keyboard, compared to 67 letters written with the keys of the keyboard, It is much easier and simpler to learn, learn, and use, because you enter the old Hangul in an easy and intuitive combination with an additional go key.

C. English Keyboard

In English keyboards, English uppercase and lowercase letters become the main input characters, but in addition, various symbols and symbols, and various Roman / Latin characters other than English letters can be easily inputted systematically by using three thumb shift keys. 36 to 39 show the arrangement of four different English keyboards developed in the present invention, which differ only in the arrangement of the English letters and the rest are the same in all respects. The lock on the bottom right of the keyboard

(4A) is used as a function key for easily inputting the number and sign assigned to the top of the shift-touch type area. In addition, the three

keys

2C, 2D, and 3B in which a sign or a symbol are assigned to the right side of the keyboard can be converted to a functional key as necessary. E.g,

The key 3B is denoted as a doubler of an English keyboard, and when an alphabet key is input at the same time, an alphabet letter corresponding to the key is input twice, which greatly improves the comrade batting ratio, which is very important in the English keyboard. 36-39 may be used as a separate key, but the right hand middle finger or the reference finger (38 or 39) of the ring finger may also be used as a double key.

The nunix-S arrangement shown in FIG. 36 is entirely newly developed in the present invention. Like the Dvorak keyboard, the consonant key and the vowel are separated from the left and right, and the vowel is placed on the left side while maximizing the positive battering rate. In addition, as shown in the performance comparison with previous keyboards, the overall keyboard performance is maximized, such as maximizing the baseline and baseline utilization, optimizing the finger utilization distribution, and reducing the batting average. It is designed keyboard.

The Nunix-Q array shown in FIG. 37 is based on the standard QWERTY array, and since the QWERTY and other alphabetic letters have only three shades of “M”, “B”, and “N”, the existing QWERTY keyboard It is designed to be easily adapted to QWERTY users due to its excellent compatibility with. The Nunix-D array shown in FIG. 38 is based on the Dvorak array, and the “W”, “V”, “Z”, “X”, “M”, and “B” shaded with the Dvorak array and other English letters. It is designed to be relatively easy to adapt to existing Dvorak keyboard users because it only has 10 of “A”, “O”, “I” and “U”. You can increase the consistency by using the key array of the reference stage as the original Dvorak array, but the original array has higher than necessary use and index finger stretch ratio. O ”and“ U ”and“ I ”are arranged interchangeably. The Nunix-C array shown in FIG. 39 is based on a Colmack array, since only four of the M, K, J, and B shaded with the Colmac array and other alphabets. It is designed to be easily adapted to Colmac keyboard users.

40 is a general key is a code

Only the arrangement of characters to be input when used with (45E) is shown. In FIG. 40, the keys of the part 161 shown in bold solid lines are called accents.

In connection with 45E, the symbols shown in FIG. 40 are inputted, but Altgial 129 or

In connection with 47E, as shown in FIG. 43 or FIG. 44, it is used for inputting an accented character, that is, an accented character. As can be seen by comparing FIG. 40 with FIG. 43 and FIG. 44, FIG.

From the code entered in conjunction with

Intuitive and easy to infer the accent input in conjunction with the user to minimize the burden of the keyboard layout memory. Key to Table 17

The characters entered in conjunction with

The accented characters entered in conjunction with the diagram are shown in the diagram, and there is a visual direct or indirect association so that the relevant accented characters can be easily inferred from the sign characters.

41, the same arrangement as that of FIG. 40, that is, the general key

When used with (45E), only the arrangement of characters entered is shown. The difference between the two figures is that the keys are classified differently in bold solid lines. In FIG. 41, the

portions

162Q, 163Q, 164Q, and 165Q indicated by the thick broken lines represent the keys used to input basic sentence codes by using the QWERTY array alone or in combination with the shifted portions. , 164 and 165 are the basic sentence code arrays of the corresponding Nunix keyboard, respectively. For example, in QWERTY, the punctuation marks “,” assigned to three sections (165Q) of four columns, eight columns (48), four columns, nine columns (49), and four columns, A columns (4A), are used. Six punctuation marks, “<”, “.”, “>”, “/”, And “?” Are assigned to the six keys of the last portion 165 shown in bold solid lines in the arrangement of the present invention. In the keyboard of the present invention, the basic sentence codes inputted by the single letter in the qwerty array are all placed at the reference stage, and the basic sentence codes inputted using the shift in the qwerty array are all arranged at the top. The leftmost nine keys at the top have the most popular world currency units, and the right four have the most used quotes in European keyboards. In addition, a few more symbols were selected and placed in the remaining position in the convenience prompting batter area. It was added considering the use of iron. 42 is a general key

Or, when used with Shift-Algital, indicates an array of letters or accents that are entered. The keys of the portion 161 shown in solid lines in FIGS. 43 and 44 are used as an actuation key and the other general keys are keys for inputting general characters. In Figures 43 and 44, the accent action brackets 161, which are indicated by bold solid lines, are used as the corresponding dead keys when used together with Altgial,

When used as such, it is used to enter the corresponding diacritical mark. For example, two steps of two rows of keys (22)

(45E) inputs the symbol “~” which is input when the first step of column Q10 (10) key of the QWERTY keyboard is pressed with the shift, and the same key 22 is used together with Altzial in FIG. The upper dead key "~" is input as shown, and the same key 22 is

When used in conjunction with the upper coupling separator "~" is input as shown in Figure 43, the same key 22

+

When used with, the lower coupling identifier “~” is input as shown in FIG. 44. In the preceding sentence, the same character “~” was used in four cases, symbol, upper dead key, upper join delimiter, and lower join delimiter, which are actually written using different Unicode and also different kinds of characters. It can be called a letter, but Table 18 shows the difference in more detail. Key from Table 18

I

While the relevant sign is the character that is actually entered, the dead key accent does not mean that it is actually being entered, but merely describes the part of the accent that is included in the input and output characters.

In the case of a key for inputting a general character, the “o” key 29 of the Nunix-Q array will be described as an example. In FIG. 43 and FIG. 44, “alt g + o œ” and “shift g Alt g + o → Œ ”,“

± o → œ ”,“

+

Enter – or 로 as ± o → Œ ”. An example of entering an accented English letter using the accent key is the “u” key (27) and “

Using the “y” key (26) to enter a colon, “¨” with + y ”,“ altjial_yu →

But it's actually a bit different. In other words, the former is a complex letter “

And the latter prints the combination of the base character “u” and the join delimiter “¨”. Popular accented characters can be typed more simply without using accents. For example, in FIG. 43, the “p” key 2A is replaced with “

"Is assigned," Altzial_p →

± p →

With only two keys

Can be entered. The above example was put together in Table 19, and is shown. Conventional keyboards often use the front key method, or the dead key method, to provide a method for inputting up and down characters, but the back key method does not provide an easy and systematic way to enter a combination separator. . The keyboard layout of the present invention efficiently provides the two types of character notation provided by Unicode.

Figure 45 is a general lock

(4A) shows the arrangement of the characters that are input when pressed, so that most of the characters are related to numbers or placed at the top, so that the basic symbols can be easily entered using the keys in the easy touch type area. It is. That is, the numbers and symbols arranged at the top of the qwerty array are arranged in parallel in the corresponding columns of the reference stage 117 and the top 116 in FIG. Meanwhile, numbers at the top of FIG. 45 are numbers used as superscripts. Thus, the arrangement of characters shown in FIG. 45 is engraved on each face because most of them can be directly inferred from the information on the top face of the actual keyboard arrangement of FIG. 23 or 25 and immediately identified through the image keyboard if necessary. Even if you do not lose, there is no big problem to use. 46 is a general key

±? Or shift_

When used as ± ?, it indicates an array of characters to be entered, the top digits represent subscript numbers, and the top and bottom “+”, “-“, “=”, “(“, and “)” symbols respectively. Indicates the superscript and subscript.

Throughout the keyboard system of the present invention can be used to easily enter characters or symbols that are used a lot for each major, in addition to the general keyboard. For example, if you systematically assign four letters to each general key such as math sign board, physical sign board, chemical sign board, and international phonetic sign board, 172 letters will be assigned to one keyboard and on-screen keyboard. By operating with a predetermined hot key, you can directly input the desired symbol through the keyboard while seeing the layout of the entire keyboard at a glance. If there are more than 172 symbols for each major, the keyboard arrangement may be designed by classifying the major and major symbols such as the mathematical symbol I keyboard and the mathematical symbol 2 keyboard. In FIG. 47, an example of the left side of the virtual mathematical symbol keyboard is shown as an example. The lower left of the four characters printed on each key is used when the key is used alone.

When used with, the bottom right

When used as

When used as in the following, each symbol is input. These major sign boards can be viewed as a separate keyboard like the English keyboard or the Korean keyboard, but can be used as a component of the entire keyboard system as easily as the Korean / English mode switching is done immediately and naturally.

D. Touch Screen Korean Keyboard on Smartphone / Tablet PC

The 8 × 3 array shown in FIG. 48 uses the consonant array as it is, based on the current standard double keyboard for computers, and accepts only 10 basic collections except for the multiple collections ㅐ and 하였다. In general, the left consonant of the keyboard is arranged to the left of the keyboard and the vowels to the right of the keyboard to make the most of the two-handed or two-handed body.

In the keyboard layout of FIG. 48, a typical Korean / English conversion key, a letter / signal number conversion key, a space key, a backspace and an enter key are disposed. It is arranged on the side.

In FIG. 48, 24 basic Hangeul alphabets are displayed, so anyone who knows Hangeul can easily input Korean by looking at this arrangement similar to the standard double-bolt type keyboard layout. The built-in input method is very similar to the sequential inputs that are commonly used, but the only difference is that when you enter the consonant of the base, press the bell marked with the bell first, and then enter the bell or the bell. Is to type keys at the same time.

However, the main Hangul input method of the present invention, which will be used a lot, is the Hangul syllable partial simultaneous input method, although the initial key and the neutron key may be sequentially input, but the input is simultaneously input and the final key and the corresponding initial key. Accordingly, the same syllable part of the Hangul syllable can be simultaneously input to a syllable composed of the basic Hangul elements registered in the basic position of the keyboard of FIG. 48. However, additional strokes are required to input Korean syllables containing double consonants or double vowels. As shown in FIG. 48, in the structure in which the 24 basic alphabets are separated from the left and right, more than 80% of the Hangul partial simultaneous input rate is possible, so that the advantages of the partial simultaneous input can still be greatly utilized.

In FIG. 48, a symbol is displayed on the right side of each key, and these symbols are called a symbol displayed at a sign place. When you press a key, the default phoneme placed at the first place appears on the screen, and when you release your finger, the phoneme is actually entered, but if you press the key for more than a certain time (for example, 1 second), A letter appears and the sign or character is entered when you lift your finger. Numbers are assigned to the sign positions of the keys at the top of FIG. 48. For odd numbers of 3, 5, 7, and 9, 2, 4, 6, and 8 are input by using even-numbered keys. For example, if you press a key that has a number 2 assigned to it, it will initially show "ㅈ", but if you press and hold it for a little longer, then release it if you release 2, but if you press it a little longer, numbers 2 and 3 will appear and you can select the number you want. Will be entered. The input of the sign using this sign place is the same as the method used in the existing Google short vowel keyboard and the arrangement is similar.

FIG. 49 illustrates a state in which all characters assigned to all sign positions, leading positions, and hot positions are displayed in the marking states of the 6 × 4 array corresponding to the marking states of the 8 × 3 array shown in FIG. 48.

In the Korean input of the quasi-three keyboard, in the case of a copper battered battered with the same key, the characters inputted according to the time interval between the two strokes do not need to be changed. This is because the number of registered letters is sufficient and the marking of letters can be made easy by using the closing key. Therefore, the method of changing the input characters according to the time interval between pressing the keyboard is also used only in very limited cases such as entering numbers in the sign place, and in most cases, it is necessary to use the base digits or leading or hot digits with good input efficiency. Enter it.

If the size of the touch screen keyboard is large enough to realize most of the full keyboard's touch screen areas, which can be touched using ten fingers, the arrangement on the computer keyboard and the semi-separated Hangul syllable partial simultaneous input method You can use as is.

The quasi-separated Hangul syllable input method of the present invention implemented in a touch screen keyboard has the above-mentioned utility in the case of using two-handed thumb or using multiple fingers in one hand, but in case of inputting only with one handed thumb. Every time you enter a syllable with a base, you need to input additional trailing delimiters. However, this disadvantage can be easily overcome as follows. In other words, if you need to use a one-handed thumb, you can enter a two-bolt input mode instead of a semi-separated one by using a simple shortcut key. Here, the two-bulb type input mode is the same as that of the semi-sebulic keyboard and all the arrangements are the same. However, the two-bulb type input mode is a commonly used two-bulb type input method. It means to output Hangul syllable by deciding.

Claims
