Description

An English keyboard for general and shorthand typing}

The present invention relates to a shorthand combined English keyboard in which keys corresponding to all English alphabets are arranged, and two or more alphabets of a consonant and a consonant corresponding to one syllable can be simultaneously input.

In addition, the present invention relates to a shorthand combined English keyboard in which the character keys are arranged inclined to both sides so as to be unfolded at the lower end about the center and the space bar or the shift key is arranged between the lower character keys.

The present invention also relates to a shorthand combined English keyboard in which letter keys in a letter key group are arranged slightly wider as the letter keys are positioned upward, and arranged in a fan shape.

In general, a keyboard for entering letters is divided into a general keyboard and a shorthand keyboard. The general-purpose keyboard is used by most people when connecting to a terminal such as a PC and inputting letters, and the shorthand keyboard is used by those who have been specially trained for faster text input at trials, conferences, seminars and press conferences.

As shown in Fig. 1, a plurality of keys are arranged in a conventional general keyboard. The key consists of a character key for inputting letters and various function keys. One letter key is usually mapped to one letter, and when pressed, the letter to be mapped is input. When pressed together with a function key such as SHIFT, another character mapped with the function key is input.

The general-purpose keyboard generally needs to input letters sequentially. That is, in order to enter the word "chair", c, h, a, i, r must be entered sequentially.

On the other hand, as shown in Figure 2a, in the keyboard for shorthand, each key is arranged, each key is mapped to a letter (letter). By the way, unlike the general keyboard, the keyboard for shorthand is divided into consonant key groups from left and right in the center, and has a vowel key group in the lower center. In FIG. 2A, a consonant key group on the left side and a consonant key group on the right side are divided around the center asterisk.

The consonant key group on the left side is for inputting initial consonants, and the consonant key group on the right side is for inputting final consonants. Assorted key groups are keys that enter a vowel between the beginning and ending consonants. Therefore, you can enter starting consonants, vowels, and ending consonants at the same time.

Referring to FIG. 2A in comparison with FIG. 1, the shorthand keyboard includes only some keys of the English alphabet. Shorthand keyboards combine letters with a limited set of keys. That is, letters are input by combining two or more keys even within the same key group.

2B shows a table of mapping rules of letters according to the above key combinations. For example, consider the case of entering the letter J. As shown in Fig. 2B, in order to input J of initial consonants, the keys of S, K, W and R must be pressed simultaneously. In addition, the P, B, L, and G keys belonging to the right consonant key group are simultaneously pressed to input J of the final consonants.

Characters input by the keyboard for shorthand and output by the mapping rule are shorthand-only letters. Shorthand-only letters are pronunciation-based letters that are different from the actual letters (words or phrases) of a general language. Therefore, shorthand-only letters should be interpreted using ordinary words to understand what ordinary letters are.

For example, when entering the word "ghetto", enter GET / TOE using the shorthand keyboard. That is, if the keyboard for shorthand inputs T, K, P, W of the start consonant key group, E of the vowel key group, and T of the end consonant key group at the same time, it applies the mapping rule to output the shorthand letters GET. . In the same manner, when the T of the start consonant key group and the O and E of the vowel key group are pressed at the same time, the TOE, which is a shorthand letter, is output. GETTOE, the shorthand letters printed in this way, should be translated into regular letters "ghetto" in preparation for the dictionary.

Therefore, as shown in FIG. 2C, the shorthand keyboard receives key signals of the shorthand keyboard (S1), converts the key signals into shorthand letters according to a mapping rule (S2), and converts the converted shorthand letters. After translating to general letters (S3), the inputted key can be output as complete letters.

In particular, in order to translate in step S3, a word dictionary by phonetic symbols is used. By the way, words are different from each other or the same hom. In this case, a collision occurs. At this time, there is a disadvantage that a person must be directly involved in translation.

As a result, the keyboard for shorthand is used only for shorthand that characterizes what people say in real time, such as trials, meetings, seminars, and more, and is only used by experts who have learned shorthand skills. In reality, it is not used as a general-purpose keyboard.

In order to solve the above problems, a technology related to a keyboard that can be used simultaneously for general use and shorthand is disclosed in [Korean Patent Registration No. 10-0708909 (published on April 11, 2007), "shorthand combined keyboard"] (hereinafter, referred to as Prior Art 1). Is disclosed. Prior art 1 has both sides of a keyboard panel; A folder attached to the upper portion of the keyboard panel and a surface of the keyboard panel flipped over and exposed; A technology including a general keypad and a shorthand keypad configured on a circuit board of a separate double-sided keypad panel detachable from a keyboard panel, and a CPU for calculating and processing input data according to a selection mode of the general keypad and a shorthand keypad is presented. .

However, the prior art 1 has the inconvenience of having to replace the keyboard top whenever the keyboard for input of the general characters and shorthand characters is doubled in one keyboard.

Meanwhile, a Korean keyboard for shorthand is disclosed in Korean Patent No. 1997-002371, "Keyboard for shorthand and shorthand method," published on March 3, 1997 (hereinafter, referred to as Prior Art 2). The prior art 2 is composed of a general mode key matrix and a short mode matrix to press the GPT key to switch to the shorthand mode to use shorthand, and press and release the GPT key to switch to the normal mode to use a keyboard that can be used in general. Suggesting.

However, the prior art 2 is different from the key arrangement of the general keyboard and the key arrangement of the shorthand keyboard. Therefore, there is a problem to switch between the general purpose and shorthand for the GPT key. In addition, as shown in Figure 1 and Figure 2a, it is practically impossible to apply the shorthand and general purpose to a single keyboard as the general key arrangement and the shorthand key arrangement are different.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

First, a key arrangement of a shorthand English keyboard according to an embodiment of the present invention will be described with reference to FIG. 3. 3 is a preferred embodiment of the key arrangement of the shorthand English keyboard according to the present invention.

As shown in FIG. 3, the keys of the shorthand combined English keyboard according to an embodiment of the present invention are the first and second letter key groups 31 and 32 in which the letters of the English alphabet consonants are marked and letters of the English alphabet vowels. ) Is composed of a letter key group 33 and a function key group 34.

The letter key group in which the alphabetic consonants are marked is arranged in duplicate from left to right in the center of the keyboard. That is, the letter key group in which the letters of the consonants are marked is divided into a first letter key group 31 located on the left side of the center of the keyboard and a second letter key group 32 located on the right side. The first character key group 31 is a key 35 for inputting initial consonants, and the second character key group 32 is a key 35 for inputting a final consonants. A character key group (hereinafter referred to as a third character key group) 33 in which letters of a vowel are written is arranged at the lower ends of the first and second character key groups 31 and 32, that is, at the center lower part of the keyboard.

As shown in Fig. 3, the first and second character key groups 31 and 32 each have keys of an array of 3x5. That is, there are three rows (or stages) and five columns. Numeric keys are arranged directly above the first and second character key groups 31 and 32. Therefore, there are 10 numeric keys. Hereinafter, when referring to the columns of the first and second character key groups 31 and 32, the numbers indicated on the numeric keys corresponding to the columns will be referred to.

The keys of the first and second character key groups 31 and 32 and the fingers pressing the same are the same as those of a general general keyboard. That is, 4, 5, 6, and 7 columns are input by the index finger, respectively, and the keys of the columns corresponding to 3 (or 8), 2 (or 9), and 1 (or 0) are respectively applied to the middle finger, ring finger, and little finger. Pressed by.

The first and second character key groups 31 and 32 are arranged to be spaced apart from each other at the lower stage. Preferably, the first and second character key groups 31 and 32 are inclined and symmetrically arranged so as to be spaced from each other at the lower end and narrowed to each other at the upper end with respect to the center line.

Further, the character keys in each group of the first or second character key groups 31 and 32 are arranged slightly wider toward the top in a fan shape. That is, between the character keys in one character key group are arranged slightly wider as the corresponding character key is located above. As shown in Fig. 3, the columns of the letter keys in one letter key group are arranged to have an angle Q.

This is because the first letter key group 31 is pressed by the fingers of the left hand and the second letter key group 32 is pressed by the fingers of the right hand in the keyboard top board. At this time, spread out your finger to press the letter keys (C, P, R, Y, M or V, X, B, F, L) located at the top of the group, and the letter keys (B, K, F) located at the bottom. Pinch your fingers to enter, W, N or J, N, D, M, Z). Accordingly, by widening between the letter keys located at the top and narrowing between the letter keys located at the bottom, the user can easily enter letters without straining the wrist or finger.

On the other hand, the third character key group 33 is composed of all six keys. As shown in FIG. 3, six keys 35 are arranged at the lower ends of the first and second character key groups 31 and 32, each of three keys. The vowel key 35 is pressed by the thumb.

In addition, in the third character key group, alphabet vowel keys are separated and arranged on both sides of the center, and a special key 37 is arranged between the separated vowel keys. A space bar 36 key is arranged at the lower end of the third character key group.

Generally speaking, English alphabet letters are composed of "consonants + vowels", "consonants + vowels + consonants", and "vowels + consonants" in terms of pronunciation. Accordingly, the first letter key group 31 is keys 35 for inputting consonants that appear before the vowels, and the second letter key group 32 is keys 35 for inputting consonants after the vowels. The middle vowel is input by the third character key group 33.

Two or more keys 35 belonging to the three character key groups may be simultaneously input. That is, the first character key group 31 + the third character key group 33, the first character key group 31 + the third character key group 33 + the second character key group 32, and the third character The key group 33 + the second character key group 32 and the first character key group 31 + the second character key group 32 may be input.

When input at the same time, the input order is a key 35 belonging to the first character key group 31, a key 35 belonging to the third character key group 33, and a key 35 belonging to the second character key group 32. It is decided in order of).

In addition, two or more keys 35 belonging to one character key group may be simultaneously pressed and input. For example, the keys "s" and "t" belonging to the left character key group 31 can be pressed at the same time.

Next, key arrangements of the first and second character key groups 31 and 32 will be described in more detail. The key arrangement of the English keyboard 30 is made according to certain rules.

First, the key arrangement and combination of the English keyboard 30 must input all English alphabet. The English alphabet consists of 26 letters. Twenty-six alphabets contain 20 alphabets of alphabet consonants B, C, D, F, G, H, J, K, L, M, N, P, R, S, T, V, W, Y, X, and Z. A, E, I, O, U, Q is divided into six (Q is a consonant, but it is classified as a collection for convenience).

 The total number of keys on the keyboard is 36. That is, the first and second character key groups each have fifteen (3 * 5) keys, and the third character key group has six keys. Therefore, the number of keys is ten more than the number of English alphabets.

All 26 alphabets are assigned to the keys of the character key group. Six alphabet vowels A, E, I, O, and U are assigned to correspond to the keys of the third character key group. The remaining 20 consonants of the alphabet are assigned to the first and second character key groups. At this time, ten alphabets overlap and correspond to two keys. One key belongs to the first character key group, and the other key belongs to the second character key group.

The overlapping ten alphabets are selected by the following criteria.

(1) the frequency used for English words

(2) the frequency used as consonants starting and ending in one syllable

(3) Are there any letters that you can remember and replace in terms of pronunciation?

Many alphabets used in words are, for example, B, C, D, F, G, H, K, L, M, N, P, R, S, T, V, Y, etc. The alphabet is J, W, X, Y and so on. Furthermore, the alphabets commonly used as starting consonants and ending consonants are B, C, D, G, L, N, M, P, R, S, T, and Y.

On the other hand, the letters that are good to remember and replaceable are C and K. For example, if C is in the first letter key group and K is in the second letter key group, it can be shortened by the consonant K, which starts by pressing C and the right key simultaneously, and ends by pressing the K and right key simultaneously. Can be shorthand with consonant C. One example of the alphabet selected by the above criteria is B, D, F, G, M, N, R, S, T, Y.

When an alphabet is assigned to each key as described above, when one of the keys is pressed, the alphabet of one corresponding key is output as a letter signal. For example, pressing C will recognize the signal as 'c'. The alphabet is printed above each key of the keyboard to indicate what letter each key points to.

In addition, fingers should not overlap when playing consecutive consonants. As described above, the first and second character key groups 31 and 32 are constituted by a matrix of 3x5, and each column is pressed by the remaining four fingers except the thumb. However, the index finger strikes two rows of the index finger.

As described above, the first and second character key groups 31 and 32 are divided into initial consonants and final consonants. The letter that comes from the beginning consonant and the letter that comes to the end consonant may be different. Therefore, the key arrangement of the first character key group 31 and the second character key group 32 may be different.

Next, the arrangement of the third character key groups 31 and 32 will be described.

As previously seen, the vowels are preferably classified as A, E, I, O, U. Preferably, the third character key groups 31 and 32 may include keys corresponding to consonants in addition to vowels. In other words, you can assign all five vowels and assign consonants to the remaining keys.

Since there are five vowels, the other key is assigned the letter Q, the consonant alphabet.

In this way, all six alphabets can be associated with the keys 35 belonging to the third character key group 33. Therefore, six vowels are assigned to six keys 35, respectively. At this time, it is divided into three on the left and three on the right.

Vowels in one English word can be contiguous as consonants. For example, -oo-, -ou-, -au-, -ee-, -ai-, -ei-, -ui- and the like. In particular, there are many cases of two consecutive vowels.

The six keys 35 should be arranged so that they can simultaneously press successive vowels as described above. The left three keys 35 are pressed by the thumb of the left hand and the right three keys by the thumb of the right hand. Therefore, the method of pressing two keys at the same time may press one of the three right sides with a right thumb while pressing one of the three left sides with a left thumb. Another method is to press two consecutive button keys 35 together with one thumb.

On the other hand, the keyboard top plate 41 further includes a function key group 34 in which function keys are arranged on both top and left and right ends of the character key group. As shown in FIG. 3, function keys are arranged on the upper ends of the first and second character key groups, and special keys or function keys used in a general-purpose keyboard are arranged on left and right sides.

Therefore, the user can use the keyboard 30 in the same way as a general keyboard. However, the arrangement of letters is different from conventional general-purpose keyboards.

Next, the configuration of a shorthand English keyboard according to an embodiment of the present invention will be described with reference to FIG. 4.

As shown in FIG. 4, the shorthand combined English keyboard 30 according to an embodiment of the present invention includes a keyboard top plate 41, a key input circuit unit 42, an input key mapping unit 43, and a PC connection terminal 44. It includes.

The keyboard top plate 41 is arranged by overlapping the character key groups 31 and 32 in which consonant letters are written from the center to the left and right, and in the lower center of the keyboard, the character key group 33 in which the vowel letters are marked is arranged.

Preferably, the keyboard top plate 41 is a character key group 31 composed of 3 × 5 keys arranged at the left of the center and marked with the letters of the initial consonants, arranged at the right of the center and ending with the consonants ( A character key group 32 composed of 3 × 5 keys marked with letters of final consonants), and a character key group 33 composed of six keys arranged at the bottom center of the keyboard and marked with letters of a vowel are configured.

Since the key arrangement of the keyboard top plate 41 has been described in detail above, it is referred to and omitted here.

The key input circuit section 42 generates a key signal when the key is pressed.

The key input circuit section 42 uses a key scan circuit of a general or shorthand keyboard. Therefore, detailed description is omitted.

The input key mapping unit 43 receives one or more simultaneously generated key signals and outputs a signal for one letter or a series of letters corresponding to the key signals. Preferably, the input key mapping unit 43 includes a memory that stores a mapping rule for searching for a letter corresponding to an input key signal.

As shown in FIG. 5, alphabet letters are produced by a combination of keys pressed simultaneously.

After storing mapping rules for alphabet letters output according to combinations of keys in a memory, the input key mapping unit 43 outputs alphabet letter signals according to input keys using stored mapping rules. That is, the signal input to the input key mapping unit 43 is a signal generated from the key input circuit unit 32 by the key 35 provided on the keyboard upper plate 41. Several key signals are input at the same time.

The input key mapping unit 43 recognizes the input signal by dividing the input signal into the first and second character key groups 31 and 32 and the third character key group 33. Characters are derived by mapping the signals input from the character key groups 31, 32, and 33 according to the mapping rules.

Meanwhile, if only one key signal of the character key group is input, the input key mapping unit 43 outputs an alphabet signal corresponding to the input key. When used in this manner, the English keyboard 30 can be used as a general keyboard.

At this time, the special key 37 is used as a shift key. That is, when one letter key 35 is pressed together with the special key 37, it is inputted in capital letters by the shift key (in the case of original capital letters, it is entered in lowercase letters). The shift key may be arranged in the function key group 34 on both sides of the special key 37 as well.

The spacebar key 36 may also be used as a shift key. That is, the special key 37 is not arranged or may be used for other purposes. In this case, the spacebar key 36 serves as a shift key when pressed with one key of the character key group.

The derived character signal is input to a computer terminal such as a PC via the PC connection terminal 44. PC connection terminal 44 connects the character signal to the PC. The PC connection terminal uses a method of connecting a keyboard to a conventional computer terminal. For example, the PC connection terminal may be implemented by PS2, USB, or wireless. Since such a technique is well known, a detailed description thereof will be omitted.

Next, the mapping rule stored in the input key mapping unit 43 according to the present invention will be described in more detail with reference to FIG. 5.

Alphabet letters of a, b, c, d, and e of FIG. 5 are input by inputting one key. That is, it is input by one stroke. Further, "me" is a word composed of two alphabets, or is simultaneously input by pressing the key of the first letter key group and the key of the third letter key group at the same time. In addition, as in a general keyboard, "m" may be input in one stroke, "e" in another stroke, and a total of two strokes may be input.

In addition, "she" is a word composed of three alphabets, or by pressing two keys of the first letter key group and one key of the third letter key group at the same time. Like the general-purpose keyboard, you can input three letters of "s", "h", and "e" respectively.

On the other hand, frequently used words may have mapping rules by abbreviations. For example, "service" is an abbreviation and has a rule consisting of the first character key group "sr" + the second character key group "vs". Therefore, the user may input "service" by simultaneously pressing the first character key group "sr" and the second character key group "vs". In addition, as in a general keyboard, seven letters of each of the "services" may be input by a total of seven letters.

In the same way, those of, whichever, etc. can also be input in only one stroke by simultaneously pressing "th" + "o" + "f", "wh" + "i" + "v", and the like.

On the other hand, when each word is entered by the mapping rule, the spacing is automatically entered. For example, if you hit "sh" + "e" and "sr" + "vr" two consecutively, "she service" is automatically entered.

Next, the effect of the shorthand combined English keyboard 30 according to the present invention will be described in more detail.

As described above, the shorthand combined English keyboard 30 may also simultaneously input two or more letters (continued) as starting consonants, vowels, and end consonants, unlike conventional general keyboards. In addition, unlike the conventional keyboard for shorthand, it is possible to input by English spelling (not spelling) rather than English pronunciation.

Conventional shorthand keyboard has a hassle to translate the input shorthand letters back to normal letters by inputting the letters by the pronunciation of English, but the English keyboard 30 according to the present invention can be directly input in general letters have.

Let's take an example of entering the word "caisson". To input the word using a conventional shorthand keyboard, first input KAIS / SON with the shorthand keyboard. Since KAIS / SON is a shorthand letter, it should be translated to the plain letter caisson. However, since the pronunciation of KAIS / SON is the same as the pronunciation of "case son", a collision occurs. In other words, the shorthand letters of KAIS / SON can be translated into both caisson and case son. Therefore, in order to select either of them, artificial intelligence judgment by context is additionally required. However, since the keyboard of the present invention can input caisson letters themselves, there is no room for collision as in the conventional shorthand keyboard. This is because the keyboard of the present invention can enter all the characters as a general keyboard.

Therefore, the keyboard of the present invention is similar to the keyboard for shorthand, but the input method is actually a general keyboard.

Meanwhile, the shorthand combined English keyboard 30 may also be used as a general keyboard and a shorthand keyboard.

The pronunciation of the consonants can be entered as the letters of the consonants. In a conventional shorthand keyboard, vowels are distinguished by pronunciation. For example, they are largely divided into short vowels and long vowels of a, e, o, i, and u. However, the method of writing each pronunciation may be wrong. The long vowel u may be represented by -oo-, -ou-, -eu- and the like. In a conventional shorthand keyboard, all of these notations are entered as AOU.

In the present invention, it is necessary to determine only the notation for writing each pronunciation for the pronunciation of the vowel. For example, the long vowel u-> -eu-, the long vowel a-> -ea- and so on. Therefore, when entering feet, you can write it as feat. If feat is described, it means the word pronounced [fi: t], not the word "feat". Therefore, as in the conventional shorthand translation, feat, a shorthand-only letter, is [fi: t], and the collision occurs with the letters "feet" and "feat", and either of them should be determined by the context.

Such a translation program may be installed in a terminal such as a PC or may be manufactured in an IC chip or the like and installed in hardware on a keyboard.

However, using the English keyboard 30 of the present invention, a short reporter can hear the feet in the field and directly input the feet instead of entering the feat. In other words, the short story of the field can be described as feet directly because the hearers can know whether the sound heard by [fi: t] means feet or feat.

Therefore, using the English keyboard of the present invention, the shorthand hears the sound and inputs it as possible letters, and can enter the letters corresponding to the pronunciation only when the correct word is not known. In this way, if the reporter hears the words and inputs the spelling letters, the conventional translation work becomes very easy.

In other words, if the conventional shorthand keyboard had to translate the shorthand letters, the shorthand using the keyboard of the present invention only had to be about the level of correction in the translation level.

In addition, the shorthand combined English keyboard according to the present invention can be used by general users who are not shorthand experts. That is, unlike a general keyboard, the key layout is different, but since all alphabets exist on the keyboard, letters can be input by entering keys one by one.

As the general user becomes accustomed to the keyboard layout of the shorthand keyboard, he can simultaneously press visible keys (keys arranged on the keyboard) and become familiar with the method of simultaneous input. And learning mapping rules, such as the input of boilerplate, will allow you to enter keys much faster.

In this way, the shorthand input method, which is used exclusively for shorthand professionals, can be easily accessed by general users.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the Example, this invention is not limited to an Example and can be variously changed in the range which does not deviate from the summary.

The present invention is applicable to the development of a shorthand combined English keyboard that can be arranged at the same time the keys corresponding to all English alphabets, two or more alphabets of the beginning consonant, vowel, end consonants corresponding to one syllable.
