JP4974010B2 - Input method of portable input terminal - Google Patents

Description

  The present invention relates to an input method for a portable input terminal.

Currently, small devices such as mobile phone terminals have advanced functions that are comparable to previous personal computers due to the development of semiconductor technology.

Therefore, these small input terminals are also required to have high-level character and code input functions and editing functions, or operability suitable for connection to the Internet, as in a general personal computer.

However, in these small input terminals, it is an essential prerequisite that miniaturization of the maximum is essential, and the number of keys is only about one-fifth that of a personal computer keyboard. It was very difficult to meet.

Currently, the Japanese input method used to win a high level of input with a small number of keys, especially the so-called numeric keypad, is common in mobile phones. This is a method in which another type of operation is added to confirm the character sound.

The current input method of a so-called numeric keypad type mobile phone is a method based on the Japanese syllabary diagram starting from Patent Document 1.

That is, the ten-key and five-stage character arrangement of the Japanese syllabary diagram is associated with the numeric keypad, each key is represented by a consonant line, and the vowel is determined by the continuous key of the consonant key.

This includes a method of determining a vowel by depressing a vowel key or another type of device for determining a vowel stage provided separately as in Patent Document 2 and Patent Document 3.

In this way, by adopting an excellent method corresponding to the Japanese character that the Japanese input of the mobile phone relies on the Japanese syllabary figure, it reduces the sense of resistance during use and leads to a certain level of operability. Yes.

However, the current mobile phone input method starting from Patent Document 1 has a drawback that the number of touches including the case of Patent Document 2 is extremely large.

On the other hand, for example, the idea of Patent Document 3 in which the vowel stage is determined by depressing another device in addition to the determination of the consonant line, in principle, achieves a high degree of operability. There remains a problem with operability in the input operation.

That is, in the idea of Patent Document 3, the numeric keypad placed on the surface of the casing plays a role in determining the consonant stage, and the vowel stage is determined by depressing another type of device placed on the back of the casing.

In this case, since the numeric keypad and the operation device can be operated simultaneously with another finger of one hand, the determination of the consonant level and the determination of the vowel level are made almost simultaneously, so that in principle it is possible to input very quickly.

However, in the actual input operation in this method, the consciousness of the input operation of the numeric keypad placed on the surface of the casing and the consciousness of pressing down another device placed on the rear face of the casing are not those on the same surface (reversely It is placed on the back of the housing, while the sense of contradiction and the consciousness of the input operation of the numeric keypad placed on the surface of the housing are linear from right to left and from top to bottom. The actual operability does not become high because of the contradiction between the consciousness of pressing down another type of device and the fact that it has the character of selecting four points placed one up and down and left and right.

Regarding the determination of consonant steps and vowel steps in a numeric keypad, there is a method of Patent Document 4 in which a key in charge of a vowel is arranged so as to surround a consonant key of the first stroke without fixing the position of the vowel key. .

This is a very good idea, and an ideal effect can be expected if the input keyboard consists of a considerable number of keys.

However, since the number of keys is limited in an actual mobile terminal, there is a positional relationship between a key having a function for automatically determining a vowel stage that appears in this way and a key of a previously determined consonant stage. However, it takes a variety of forms, and there is a disadvantage that the actual input operation becomes troublesome.

In contrast to these excellent methods for inputting Japanese sentences, in the case of English input, a method in which 3 to 4 English character mothers are assigned to one key is used.

Generally speaking, the problem to be solved by the present invention is to propose a 3-row 3-column 9-key mobile input terminal with a reduced number of keys compared to the conventional numeric keypad, and with this small number of keys, Japanese input, The purpose is to provide a more rational interface by constructing a keyboard system corresponding to the characteristics of input objects having different personalities such as English text input, numeric input, code input, and the like.

The difficulty in inputting Japanese and English text in a 9-key portable input terminal is that a large number of input objects such as the Japanese syllabary and 26 alphabets must be processed with a maximum of 9 keys.

Generally speaking, it is difficult to input codes with the currently used numeric keypad type portable input terminals. Alphabet characters that represent the Japanese alphabet and the alphabetic characters that represent the Japanese alphabet, or 26 alphabets for English input. There is not enough room for the code to be displayed on the keyboard filled with, and it is necessary to display the code on the display of the screen and search for the required code from this code or code list with the cursor. In other words, it is different from the keyboard operation for character input and is somewhat unstable and generally requires a method with a large number of operations.

On the other hand, the major feature of the Japanese input system in the current numeric keypad type mobile input terminal compared with the input method of a general personal computer is already input as shown most characteristicly in the case of a mobile phone. From the selected context or the temporal, spatial, and social environment at the time of input, a very large number of input candidate characters are displayed on the screen, and the input user selects a required character from the input candidate characters. The system is well developed.

Although this is a very important technological development, the practical difficulty is that when selecting this candidate character, as in the case of code input, the search for this list of candidate characters is performed by the cursor, that is, This is different from the keyboard operation in Japanese input, and is somewhat unstable and generally requires a method with many operations.

"Solving Japanese input problems"

The present invention relates to a Japanese input using a 3-by-3 9-key Romanized alphabet input keyboard with a reduced number of keys compared to a conventional numeric keypad used for a portable input terminal. Alternatively, the shortage of the number of keys is solved by doubling the number of keys at a time by inputting two letters of consonants and other consonants.

The basis of the present invention is that an automatic alternation relationship is set between a consonant and a vowel or two consecutive consonants and a vowel in a portable input terminal.

When using this method, the most rational is to set up an automatic alternation between the consonant keyboard and the vowel keyboard.

However, the number of vowels and the number of consonants are separated, and it is impossible to set a full automatic alternation between the consonant keyboard and the vowel keyboard.

Therefore, in the present invention, first, an automatic replacement relationship is set between the five keys a, i, u, e, and o and a certain consonant.

In this case, if the five keys a, i, u, e, o are combined with a certain consonant during the romanization process, the five vowels a, i, u, e, o are input. Is impossible.

Therefore, in the present invention, a key for inputting five vowels a, i, u, e, and o at their own note values without having a note value although they are formally consonants by themselves. Set consonant notes in the invention.

In addition, in order to input a character in kana, in a general method, the n key is depressed twice in succession. In the present invention, as will be described later, the n key is a consonant and a vowel or Since it belongs to a keyboard that automatically sets an alternating relationship between two consecutive consonants and vowels, a method of pressing down the n key, which is a consonant twice, cannot be taken.

Therefore, a key that belongs to a formal vowel that is associated with a consonant that is a formal consonant but has no note value, a nose note as defined in the present invention, is input to a specific key.

Further, by placing the nasal note belonging to this formal vowel on the same hard key as the consonant belonging to the formal consonant set earlier, the keys entering the automatic alternation relationship are a, i, u, e, o. One more can be added from the five keys.

As described above, a total of 6 keys including a nose note and 5 keys a, i, u, e, and o, and a total of 6 keys including a consonant note and any 5 consonant keys. It is now possible to set up an automatic replacement relationship.

The next problem is that the basics of the present invention set the automatic alternation between consonants and vowels, and double the 9 keys to achieve the same function as the 18 keys. However, the minimum required consonant in the Japanese input using the Romanized alphabet input keyboard is k, s, t, n, h, m, y, r, w, g, z, d, b, p, 14 keys, and the 5 keys a, i, u, e, o, and consonant notes and vowel notes that were set earlier, add up to 21 keys in total. This means that the frame of 18 keys obtained by setting two letters each greatly exceeds.

In order to solve this difficulty, the present invention sets k and g, s and z, t and d, h and b to the same key, and sets the four keys kg, sz, td and hb. If you press it down normally, clear sound will be input.

In the present invention, in a keyboard of 3 rows and 3 columns as a whole, an n key and consonant notes are added to four keys of kg, sz, td, and hb, and these are arranged in the order of the Japanese syllabary. , Sz, td, n, hb, 2 rows, 3 columns, 6 keys, and 5 noses, 5 keys a, i, u, e, o, 2 rows, 3 columns A one-to-one complete (partial for the entire keyboard) automatic replacement keyboard is set between the six keys, and this is called a consonant vowel automatic replacement keyboard. There are 5 letters, m, y, r, w, and p. In the keyboard of 3 rows and 3 columns as a whole, 2 rows and 3 columns have already been set so far. This means that the five letters m, y, r, w, and p need only be set on the 1-row, 3-column keyboard.

The first of the remaining difficulties is to press the t key twice in a general manner in order to input the prompt sound in the kana, but in the present invention, the td key which is a consonant is pressed. In the present invention, since an automatic alternation relationship is set between the key for inputting the vowel u and the td key which is a consonant is depressed twice in succession, it is impossible to take a method.

Therefore, in the present invention, in the entire 3 × 3 character input keyboard, the 1 × 3 keyboard excluding the 2 × 3 key where the consonant and the vowel automatically change one-to-one. , 5 characters m, y, r, w, p are set, and the hiragana, katakana, and kanji characters of the normal size input just before are converted into small fonts as one code of the rest. However, this problem can be solved by setting a key called a large letter key in the present invention, which has a function for converting small hiragana, katakana, and kanji into ordinary fonts. Will be resolved.

Furthermore, in the present invention, when this character large / small mark is pushed down immediately after a letter such as hiragana, kanji, or katakana that has been generally entered, not only in this case, but these are already entered. The character set of the normal font is set to have a function of converting the character of the small font into the normal font.

Also, in this case, if this character large / small mark is pushed down after designating a character group such as hiragana, kanji or katakana that has already been entered with a cursor, etc., the character group of these ordinary characters that have already been entered will be reduced. Is set to have a function of converting a small character group into an ordinary font.

The second of the remaining difficulties is that the five letters m, y, r, w, p are directly a, unlike the five keys kg, sz, td, n, hb. This is a problem that a one-to-one full automatic replacement relationship cannot be set between the five keys i, u, e, and o.

Therefore, in the present invention, when the key is depressed once in this 1-row and 3-column keyboard, the three letters m, y, and r are input, and when the key is depressed twice in succession, this input is canceled. Thus, the setting is made so that two capital letters, w and p, are entered.

More specifically, it is as follows.

In the present invention, when the first Japanese input screen, that is, the Japanese input screen by Japanese Romanize is called, or after entering another input screen from there, the Romanization of the alphabet entered again by depressing the input type switching key. In the Japanese hiragana input scene, the five consonant alphabets of kg, sz, td, n, and hb arranged in the order of consonant notes and the order of the Japanese alphabet shown in FIG. A 3-row, 3-column consonant keyboard consisting of the arranged three consonant m, y, r is called.

When one of the keys of this consonant keyboard is depressed, the consonant character (including the consonant note) that the key is in charge of is input, and at the same time, as shown in the upper two lines of FIG. , A nasal note, followed by a vowel keyboard with 2 rows and 3 columns consisting of five keys a, i, u, e, o arranged in the order of the Japanese syllabary.

Then, when you press any key on this vowel keyboard, this vowel key is combined with the previous consonant key, and the input of a certain hiragana is completed, and the first 3 rows and 3 columns consonant keyboard is automatically called. .

For example, when the kg key of the consonant keyboard is pressed down for a long time on the input screen that is entered first, the key automatically changes to the vowel keyboard at the same time as g is input, and then this key is pressed when the same key is pressed down. As a key on the vowel keyboard, automatically returns to the consonant keyboard as soon as the character is input.

Here, when the consonant key of the consonant keyboard is further depressed, the keyboard automatically changes to the vowel keyboard at the same time as the consonant key is input, and when the same key is subsequently depressed, this key is changed to the vowel key. As the nose sound key is entered, the character automatically returns to the consonant keyboard as soon as the character is entered.

Next, when the kg key of the consonant keyboard is normally depressed, the keyboard automatically changes to the vowel keyboard as soon as k is entered, and when the same key is subsequently depressed, this key is used as the a key of the vowel keyboard. It is recognized, and at the same time, the Kanji character is input, and at the same time, it automatically returns to the consonant keyboard.

With the above, using the 3 rows and 3 columns Japanese input keyboard, hiragana is input with a total of 6 touches.

If this is further converted into kanji, an input such as ophthalmology can be realized. However, the number of touches required for the above input is exactly the same as the number of touches that are input using a so-called qwerty board on an ordinary personal computer.

The next problem is how to set the alternation relationship between the keyboard in which the 2 × 3 consonant vowels are automatically changed one-on-one and the remaining 1 × 3 purely consonant keyboard. It is a problem to say.

Therefore, when the m key of a pure consonant keyboard is pressed down on the first input screen, m is input and at the same time, the 2 × 3 consonant vowel automatic alternation keyboard automatically changes to a vowel keyboard. Then, for example, if the a key of this vowel keyboard is depressed, this m key is set so that the vowel keyboard automatically returns to the consonant keyboard at the same time as the m character is input together with the a key of the vowel keyboard. .

Here, when the consonant key of the consonant keyboard is further depressed, the keyboard automatically changes to the vowel keyboard at the same time as the consonant key is input, and when the same key is subsequently depressed, this key is changed to the vowel key. As the nose sound key is entered, the character automatically returns to the consonant keyboard as soon as the character is entered.

Subsequently, when the m key of a pure consonant keyboard is continuously depressed twice, as shown in the third line of FIG. 1 (b), this m key is changed to the p key and p is inputted. At the same time, in this case as well, the 2 × 3 consonant vowel automatic alternation keyboard automatically changes to a vowel keyboard, and then, for example, when the a key of the vowel keyboard is depressed, the p key is aligned with the a key of the vowel keyboard. It is set to automatically return to the consonant keyboard as soon as the letter is input.

Furthermore, when the consonant key of the consonant keyboard is depressed, the keyboard automatically changes to the vowel keyboard at the same time as the consonant key is input, and then when the i key of the vowel keyboard is depressed, this key is As the i key is entered, the same character is entered and at the same time, it automatically returns to the consonant keyboard.

With the above, a Hiragana manuscript is entered with a total of 8 touches using a 3 x 3 Japanese input keyboard.

If this is further converted into Kanji characters, for example, full input will be realized, but the number of touches required for the above input is required for inputting consonant notes rather than the number of touches when inputting using a so-called qwerty board on an ordinary personal computer. There are only one touch and the other parts are exactly the same.

Another problem is how to set the input for stuttering.

To solve this problem, a normal personal computer is used by taking advantage of the fact that the y key is placed on a pure consonant keyboard with 1 row and 3 columns, and is separated from the forced one-to-one alternation of consonant vowels. In the same way as in the case of, and in the case of the prompt sound input already explained, there are two methods of changing the character that has been entered by the usual method into a small font using a large character. Conceivable.

In the first case, for example, when the sz key of the consonant keyboard is pressed down for a long time, z is input, but when the y key belonging to the pure consonant keyboard is pressed down, a consonant group indicating the syllable zy is input. At the same time, the keyboard automatically changes to a vowel keyboard, and then when the o key of this vowel keyboard is depressed, the keyboard is automatically returned to the consonant keyboard again as soon as the letter is input.

Next, when the consonant key on the consonant keyboard is pressed down, the keyboard automatically changes to the vowel keyboard at the same time as the consonant key is input, and then the u key on this vowel keyboard is pressed down. As soon as a character is entered, it automatically returns to the consonant keyboard.

Next, for example, when the sz key of the consonant keyboard is normally depressed, the keyboard automatically changes to the vowel keyboard at the same time as s is input, and then when the i key of this vowel keyboard is depressed, As soon as a character is entered, the keyboard automatically returns to the consonant keyboard.

With the above, four characters of Hiragana are input, and if this is further converted to Kanji, for example, the input of boss is realized. In this case, the number of touches required for the above input is a normal personal computer, so-called qwerty board Only one touch required for inputting consonant notes is more than the number of touches when inputting using, and the other parts are exactly the same.

When p is input to a stuttering input by pressing down a pure consonant keyboard twice in succession, for example, when the r key of a pure consonant keyboard is pressed down twice on the first input screen, When the r key is changed to the p key and p is input, the consonant vowel automatic alternation keyboard changes to the vowel keyboard. When the y key of the pure consonant keyboard is subsequently input, the y key in this case Is neutral in alternation between consonants and vowels, a consonant group representing the py of a stuttering sound is input and the keyboard stays as a vowel keyboard, and then, for example, when the o key of this vowel keyboard is pressed down, As soon as a character is entered, it automatically returns to the consonant keyboard.

Thus, the two characters Hiragana Pyo are entered. In this case as well, the number of touches 4 required for the above input is more than the number of touches when using a so-called qwerty board on an ordinary personal computer. Only one touch is required, and the other parts are exactly the same.

The problem of prompt sound input mentioned earlier will be explained in a more systematic manner, taking the case of a quick input, and the td key is normally used on the consonant vowel automatic replacement keyboard following the input of the previous sound. If you press down and enter t, and then continue to press down the same key that automatically changes to the vowel keyboard, this key automatically becomes the u key of the vowel keyboard that appears, and it is entered together .

If the m key of a pure consonant keyboard is pressed down twice in succession, this key changes to a large / small key, and the character that was input immediately before it is converted into one. The alternation between consonants and vowels is neutral, and the situation where a consonant keyboard is created after the input of the first vowel part continues.

On this consonant keyboard, the td key is normally depressed to input t, and then the o key of the automatic consonant vowel replacement keyboard that has been replaced with the vowel keyboard is depressed to input hiragana and.

In this way, in order to input a short time, in the case of the present invention, it is necessary to press the key six times in total, and the number of key presses is doubled as compared with the case of the personal computer three times.

As described above, the number of key depressions of the present invention is the same as that of a personal computer except for the case of a sound that is exceptionally increased in the number of depressions and a stuttering sound that is input using a large character.

As described above, in the Japanese input using the alphabet-based input keyboard by the 9-key Romanize of 3 rows and 3 columns used for the portable input terminal, two keys, consonant and vowel, or consonant and other consonant are used as one key. If the automatic alternation input system for inputting the characters is illustrated here again, it is as shown in FIG.

That is, from the top of the 9-key hard key of 3 rows and 3 columns of FIG. 1A, the first column key from the left in the first row is a consonant note key, and the second column key is a kg key. The third column key is the sz key, the second column first column key is the td key, the second column key is the n key, the third column key is the hb key, The keyboard that is set so that the key in the first column of the third row is the m key, the key in the second column is the y key, and the key in the third column is the r key It will be the keyboard that goes.

On the other hand, from the top of the three-row, three-column 9-key hard key shown in FIG. 1B, the first column key from the left of the first row is a nose note, and the second column key is the a key. 2 rows and 3 columns with the third column key as i key, second row and first column key as u key, second column key as e key-and third column key as o key A total of six keys enter the consonant key as a vowel key.

Further, regarding a total of three keys of the letter large mark, the w key, and the p key in FIG. 1B, the m key of the first column key in the third row in FIG. 1A is further continued. If you press and hold down, a neutral letter large / small sign will be entered for the consonant and vowel alternation, and if you continue to press the y key of the second row key continuously, the w key that is the consonant key will be entered again, If the r key of the third row key is further depressed continuously, the p key as a consonant key is input again.

Among these three keys, two keys, a w key and a p key, other than the character large and small letters neutral to consonant and vowel alternation, together with the consonant keyboard of FIG. ) 2 rows and 3 columns, and a total of 6 vowel keys are automatically replaced.

In the above case, the y key in FIG. 1 (b) becomes a consonant y sound when a vowel is input immediately before it, and is combined with the vowel input after that, and the consonant key and vowel The key change is realized, but if a consonant is input immediately before it, it will be combined with the vowel input after that as a code to scramble this consonant. Neutral for automatic consonant and vowel alternation system.

For users who are not familiar with Roman letters, in the present invention, as shown in FIG. 2, a is added to these consonant keys and the romanization is performed. , U key is U key, e key is E key, o key is O key, kg key is Kag key, sz key is Saskey key, td key is just key , N key as a key, hb key as a hab key, m key as a key, y key as a key, r key as la key, and w key as w key. A keyboard is also prepared in which the p key is designated as a pie key.

The consonant vowel alternation system of the present invention will be briefly described as follows.

Except for the case of the letter large sign and the y key as a stuttering code, when any one key of the consonant keyboard is effectively depressed, the corresponding consonant is input and at the same time, automatically 2 rows by 3 columns. A vowel keyboard is called.

When any one key of the vowel keyboard of 2 rows and 3 columns is depressed, the vowel is input and at the same time, the vowel keyboard of 2 rows and 3 columns is changed to a consonant keyboard of 2 rows and 3 columns.
"Solving English input problems"

As described above, the basis of the present invention for Japanese sentence input is to halve the number of hard keys required for Japanese sentence input through a system of regular alternation of consonants and vowels.

This system is constructed by paying attention to the phenomenon of almost regular alternation of consonants and vowels that actually exist in Japanese, and formally implementing this.

On the other hand, since such a phenomenon does not exist in English, the only way to reduce the number of keys required for English input in English input is to manually switch the keyboard.

Therefore, the present invention halves the number of hard keys required for English input by manually depressing a separately provided keyboard switching key.

That is, in the English input of the present invention, in the 3-row, 3-column 9-key English input keyboard used for the portable input terminal, the alphabet 26 letters are assigned to two keyboards, and one of them is entered into English input. The keyboard that appears first is the English input table keyboard, and the portable input terminal is set so that the other English input back keyboard is called by pressing down the keyboard switch key during input using this keyboard. To do.

Further, after the input by the English input reverse keyboard called by depressing the keyboard switching key, the keyboard is automatically set to return to the original English input table keyboard.

By adopting such a method, the present invention has a large number of key depressions when inputting from a portable input terminal employing a conventional keyboard in which three or four alphabet letters are arranged on one key. It overcomes the flaw that the number of depressions is uneven depending on the key, and pursues rhythmic and high-speed English input.

However, there are 26 alphabets, and even if a key is assigned input of two letters and this is switched by manually depressing the keyboard switch key, it can only provide up to 18 keys. The system corresponding to the 26 alphabets cannot be made.

In response to this difficulty, the present invention utilizes the situation of complementary arrangement of letters in the spelling of English words, and allows a single hard key to receive input of a plurality of letters to make them two virtual keyboards. This difficulty is overcome by adopting a method of sorting and replacing them manually.

That is, the present invention makes use of the complementarity seen in the spelling of the above-mentioned English words, and is a portable input in which ckq, hiy, gj, sxz, and uvw are set to 14 keys and 5 sets of English character mothers each as one key. Although the terminal is proposed, the verification of the complementarity will be described later, and only the result will be shown here.

According to the present invention, the number of keys required for inputting English text can be reduced from 26 to 17.

Therefore, one of the basic elements of the present invention is a mechanism in which a plurality of alphabetic characters set to one key are simultaneously input with one touch on an input keyboard in the case of a 3-by-3 numeric keypad type English input. There is a point to set.

The mechanism that multiple alphabetic characters set to one key are simultaneously input with one touch is not meaningful only in the input keyboard in the case of 9-key English input of 3 rows and 3 columns, In general, an important function is shown even on a keyboard having a different key arrangement, a keyboard having a larger number of keys, or a keyboard having a smaller number of keys.

The second problem is that in the present invention, all the English character mothers are assigned to the English input front keyboard and the English input back keyboard, but in order to enter the latter from the former, it is necessary to depress the keyboard switching key.

Therefore, how to reduce the number of times that the keyboard switch key is pressed becomes an important problem.

The present invention concentrates relatively frequently used characters in English sentences on the English input table keyboard, and places relatively low occurrence characters on the English input back keyboard in English sentences. Therefore, the number of cases where it is necessary to depress the keyboard switching key is reduced.

In this case, verification of which alphabet is relatively frequently used in English sentences will also be performed later, and only the result will be shown here.

As described above, in the present invention, the English sentence of the 9-key mobile input terminal of 3 rows and 3 columns is based on the two elements of the complementarity of the letter in the English word spelling and the difference in the frequent appearance of the letter in the English sentence. A mobile input terminal is proposed in which the alphabet letters set on the input table keyboard or combinations of alphabet letters are a, e, hiy, n, o, r, sxz, t, uvw.

The present invention has an effect of relaxing the limitation on the limited number of keys regardless of the form of the input keyboard and the number of keys.

It is an important issue how to arrange the nine alphabet letters or combinations of alphabet letters of a, e, hi, n, o, r, sxz, t, uvw. In the invention, the alphabets are arranged in the order of the most universal alphabet in the English-speaking world.

More specifically, as shown in FIG. 3 (a), a, e, hi, n, o, r, sxz, a, e, hi, n, o, r, sxz, As shown in FIG. 3 (a), a portable input terminal having nine letters of t and uvw or a combination of letters basically arranged in alphabetical order as shown in FIG. 9 keys of 3 rows and 3 columns 9 keys 1st row 1st column a, 2nd column e, 3rd column hi, 2nd row 1st column n, 2nd column o , A portable input terminal is proposed in which the keys r, rx in the third column, sxz in the first column, t in the second column, and uvw in the third column are arranged.

The English input back keyboard of 3 rows and 3 columns combined with the English input table keyboard in the present invention, that is, the English input back keyboard English type referred to in the present invention is therefore set to the English input table keyboard from the 26 alphabets of the alphabet. Eight sets of b, ckq, d, f, gj, l, m, p after subtracting nine sets of letters or combinations of letters a, e, hiy, n, o, r, sxz, t, uvw It will be a letter or a letter combination.

Thus, eight sets of characters or combinations of characters are arranged for 9 keys in 3 rows and 3 columns, so that one key is left. In the present invention, a character large and small mark is added to the remaining one key. Place.

In the present invention, when the character large / small mark key in the case of English input is depressed, the lowercase English character input immediately before or after the input is further changed to uppercase, and the uppercase English character is converted to lowercase. Set to.

In addition, if this letter key is pressed down after specifying a part of a sentence or word that has already been entered, the lower case letter will be changed to upper case and the upper case letter will be changed to lower case. Set to switch to.

Thus, the English input front keyboard set in the above, that is, the English input front keyboard according to the present invention is combined with the English input back keyboard of 3 rows and 3 columns, that is, the English input back keyboard English type according to the present invention is b, ckq. , D, f, gj, l, m, p, 8 keys with 11 letters or combinations of letters, and 9 keys including a large letter key.

More specifically, b, ckq, d, f, gj, l, m, and p8 sets of 11 letters or combinations of letters are set in the English input back keyboard, that is, the English input back keyboard in the present invention. Is a portable input terminal having a 9-key keyboard with 3 rows and 3 columns arranged basically in alphabetical order, that is, as shown in FIG. B in the first row and first column, ckq in the second column, d in the third column, f in the second row and first column, gj in the second column, l in the third column, third row and first column A portable input terminal is proposed, in which the letters large and small, the m in the second column, and the p in the third column are arranged.

In the present invention, in consideration of Japanese use, a portable input terminal with a key arrangement that places the highest priority on the order of the Japanese alphabet is also proposed.

In this portable input terminal, 9 of a, e, hi, n, o, r, sxz, t, uvw set to the English input table keyboard English type according to the present invention in order to respect the order of the Japanese syllabary. Turn r to the back keyboard from each letter or combination of letters, put ckq from the back keyboard, and in the 9-key keyboard of 3 rows and 3 columns, basically the keyboard arranged in the order of the Japanese syllabary, that is, the present invention I suggest a portable input terminal with a keyboard that supports Japanese text.

In this keyboard, nine letters of a, ckq, e, hiy, n, o, sxz, t, uvw, or a combination of letters are represented by 9 keys in 3 rows and 3 columns as shown in FIG. The nine keys of the keyboard are a in the first row, first column, hi in the second column, uvw in the third column, e in the second row, first column, o in the second column, ckq in the third column, A portable input terminal is proposed in which keys of sxz in the 3rd row, 1st column, t in the 2nd column, and n in the 3rd column are proposed, and this is called an English input table keyboard Japanese sentence correspondence type.

Therefore, the English input back keyboard Japanese type corresponding to this English input table keyboard Japanese type corresponds to the English input back keyboard English type b, ckq, d, f, gj, l, m, p. Alternatively, ckq is removed from the combination of letters and r is added instead.

In the present invention, this English input back keyboard, that is, the English input back keyboard in accordance with the present invention, b, d, f, gj, l, m, p, r, 8 sets of 9 letters or letters Is a portable input terminal having a 9-key keyboard with 3 rows and 3 columns arranged in the order of the Japanese syllabary order, that is, as shown in FIG. M in the first row and first column, l in the second column, r in the third column, gj in the second row and first column, d in the second column, b in the third column, A portable input terminal is proposed in which letters large letters are arranged in one column, p in the second column, and f in the third column.
"Solving candidate character input problems"

As already mentioned in the section of the problem to be solved by the invention, the major feature of a Japanese key input system in a numeric keypad type mobile input terminal compared with a general personal computer input method is the case of a mobile phone. As shown most characteristically, a large number of input candidate characters are displayed on the screen from already entered characters, from already entered contexts, or from the temporal, spatial, and social environments at the time of entry. A system has been developed that allows the input person to select a required character from the input candidate characters.

As already mentioned, this is a very important technological development. However, when actually selecting this candidate character, as in the case of code input, an operation of searching the list of candidate characters with the cursor. That is, there is a problem in that it is different from the keyboard operation for character input and is somewhat unstable and generally requires a method with a large number of operations.

Therefore, in the present invention, a method similar to the case of code input to be presented later, that is, from the input candidate group displayed in the same form as the actual keyboard on the screen display, corresponds to this virtual keyboard. This difficulty is overcome by also adopting a method of selecting a necessary candidate by depressing a key on an actual keyboard.

In other words, while inputting Japanese or English text on a mobile input terminal, the candidate characters that are predicted or guessed and displayed on the display screen based on the characters and context that have already been input, or by the time and environment at the time of input, are displayed. When the key of the actual keyboard corresponding to the position of the selected candidate character displayed on the screen is pressed after the shift key is pressed down after being displayed in the form corresponding to the actual keyboard of 3 rows and 3 columns, the candidate Set so that characters are entered.

FIG. 7 shows the arrangement of candidate characters in the case of Japanese input corresponding to the above conventional method, but not only that, but a plurality of candidate words for words including complementary characters in English input presented for the first time by the present invention Similarly, in the input procedure, a group of candidate words is displayed on the display screen in a form corresponding to the actual form of a 3-by-3 keyboard, and the selected candidate displayed on the screen after pressing the shift key. When the key of the actual keyboard corresponding to the character position is depressed, the candidate character is set to be input.

Here, the key to press down the shift key first is to enter the keyboard to enter the sign by leaving the keyboard that already enters the letter when the keyboard switch key is depressed, as will be touched later. On the other hand, when selecting a candidate character, the candidate character is at the stage shown on the screen for reference during the input of Japanese or English text. As a procedure to enter a new stage of input, the shift key is pressed down.

The invention of correspondence between the candidate characters on this screen and the keyboard is also applied to a keyboard input terminal having a different form from this, or a keyboard input terminal having a larger or smaller number of keys. .

In this way, the setting is made so that the normal input state is restored as soon as the candidate character is input.

In the above case, if the expected candidate character is not found on the screen, if the keyboard switch key is depressed again, a screen with a new candidate character appears, and at this point, the same as above Perform the operation to set the selected candidate character to be input, repeat the above operations as necessary, enter the selected candidate character, and immediately enter the normal input status. Set to return.
"Problems with candidate character input especially related to English character mother input"

The above is a general problem of the candidate character input problem, and the problem in the case of Japanese sentence input is solved by this, but it is configured by assigning a plurality of letters to one key as in the present invention. The problem with the actual operation of the English keyboard is that it is difficult for such a keyboard to input the character directly to determine the word immediately.

For example, if you input “you” on a conventional personal computer or portable terminal, you can immediately determine the word “you”, but if you enter “you” in the present invention, you, you, you, iou, iov, iow, iow, hou, hov 9 spellings of “how” are input simultaneously.

Therefore, in the present invention, an English dictionary is registered in the main body of the mobile terminal in advance, and is set so as to select the spelling established as an English word by assigning the spelling input here.

In this case, in addition to “you”, two words of “you” (painful and surprising interjection) and “how” are selected as spellings that are established as English words.

Therefore, the main body selects the most appropriate word based on the scene, grammar, and context at the time of input, displays this on the display screen as a continuation of the text that has been input so far, and displays the remaining two words in three rows and three. Display on the display screen corresponding to the keys of the row.

In this case, based on the input scene, grammar, and context on an input terminal that has a different form from an input keyboard with 3 rows and 3 columns, or a keyboard with more or less keys. Select the most appropriate word, display it on the display screen as a continuation of the text you have entered so far, and display the remaining two words on the display screen in a form corresponding to the form of each keyboard. It is included in the present invention as a homogeneous invention.

In the above case, if the judgment that the subject position is placed as the judgment from the context is superior to the other judgments, in this case, “you” is input to the continuation of the main text, Two words, distress, surprise, and how) are displayed on the display screen in a form corresponding to a 3 × 3 keyboard.

If the input person agrees with this determination, the input as the continuation of the text of this “you” is confirmed by simply pressing down the space key or the determination key.

If the input person does not agree with this judgment, it is appropriate from the two words “how” and “how” displayed on the display screen in a form corresponding to the keyboard of 3 rows and 3 columns. This word is input and determined by first depressing the shift key and then depressing the key of the actual keyboard corresponding to the position where the word is displayed.

In this case, without pressing down the actual keyboard key corresponding to the position where this word is displayed immediately, the shift key is first pressed down because it is in the phase where the text is input at this point. This is to enter the phase of selecting an appropriate word from the words displayed on the display screen.

Although it is almost impossible, in the above case, if the expected candidate character or word is not found in the virtual keyboard displayed on the display screen, the keyboard switch key is continuously depressed. Each time, a screen on which new candidate characters or words are arranged appears.

If the target candidate character or word is found when the keyboard switch key is already depressed in the above case, the shift key is different from the previous case because the character input dimension has already been left at that point. If you press a key on the keyboard corresponding to the position of a candidate character or word to be selected displayed on the display without pressing, the character or word will be entered and the input will be confirmed at the same time. To do.

Even in the case of a keyboard with a different form from the input keyboard of 3 rows and 3 columns, or a keyboard with a larger or smaller number of keys, in the same case, an expected candidate displayed on the display screen If no letters or words are found, each time you press the keyboard switch key continuously, a screen with new candidate letters or words will appear each time. Without pressing down, pressing a key on the actual keyboard that corresponds to the position of the candidate character or word to be selected displayed on the display will confirm that input at the same time that the character or word is entered. Set to.

In the above case, as soon as the input of the candidate character or word is determined, the normal input situation that has been performed so far is set.

In the same case, even if the candidate character or word is input to a keyboard having a form different from that of an input keyboard of 3 rows and 3 columns, or a keyboard having a greater or lesser number of keys, it is immediately Set it so that it returns to the normal input status that had been done so far.

Again, in order to observe the problem in detail, as an example of a case where the number of spellings to be allocated becomes a little more, for example, in a portable input terminal having a 9-key keyboard with 3 rows and 3 columns, an explanation will be given on the case of entering “invention”. Then it becomes as follows.

First, for the i of the invention, the three letters h, i, and y are inputted simultaneously, then n is inputted as it is, v is inputted with the three letters u, v, and w simultaneously, and e is inputted as it is. As for n, three letters of h, i, and y are inputted simultaneously, i is inputted as it is, and n is inputted as it is.

Accordingly, the input spelling includes 27 combinations of three combinations of hn, in, and yn, three combinations of ven, uen, and wen, and three combinations of tion, thon, and tyon. Spelled.

They are shown below: hvention, hnventhon, hnvention, hnuention, hnuenthon, hnuenyon, hnwention, hnwenthon, hwentyon, invention, inventon, inventon, invention, invention 27 spellings of nuention, nuenthon, yunention, ynwention, ynwenthon, ynwentyon.

If these spellings are assigned to a dictionary pre-registered in the portable input terminal, it can be seen that among these 27 spellings, only the spelling “invention” is established as an English word. Input correctly.

As an example in which a plurality of input candidates appear, for example, the word “forty” may be input.

In this case, a plurality of inputs are made only for the spelling y, and if the three spellings of forty, forth, and forti are assigned to a dictionary registered in advance in the portable input terminal, these three types are input. It can be seen that two spellings, forty and forth, are formed as English words in the spelling, but there may be forti as the spelling during input, so these two words and one spelling An incomplete spelling is an input candidate.

For example, if the forty is determined to be a more promising candidate based on the scene and context at the time of input, the forty is displayed as a continuation of the text, and the forth and forty are displayed in three lines. It is displayed on the display screen in a form corresponding to the three rows of keys.

That is, the forth is displayed at the top and leftmost of the 3 rows and 3 columns keyboard displayed on the display screen, and the forti is the right column, that is, the first row of the 3 rows and 3 columns keyboard. Displayed in the second column.

Here, when the input person selects forty, for example, if the space key or the enter key is depressed as it is, the forty is input and confirmed.

Here, when the input person chooses the forth direction, first press the shift key, and then the uppermost edge of the 3-row, 3-column keyboard displayed on the display screen, the uppermost edge of the actual keyboard corresponding to the leftmost edge, If the leftmost key is depressed, “forth” is input and confirmed.

In the present invention, when verifying the appearance rate of alphabets in English sentences and the number of touches of input by this method that relies on it, in order to confirm the appearance frequency of alphabet letters in such English sentences, almost standard English Assuming that the English constitution of the United States on the Internet and related English events are gathered at random, the frequency of alphabetic alphabets is examined.

Here, the beginning part of the preamble of the United States Constitution is taken up, and it will be briefly verified on a trial basis how practically the present invention is.

The beginning part of the preamble to the United States Constitution begins with We the people of the United States, in order to form a more perfect Union, and an established justice.

Among them, there are ten words in which a plurality of alphabets are set for one key: We, the, the, United, States, in, perfect, Union, establish, and justice.

In the case of We, three spells of we, ve, and ue are input at the same time. Among them, only we that is established as English is temporarily input as the text, and if the input person hits the space key, it is fixed as it is. Same as general input.

In the case of the the, the three spellings of the, thee (the chain that raises and lowers the yard with a shipping predicate), and tie (tie) are simultaneously established as English, but the the is temporarily input as the text from the context and frequency of use, And type are displayed on the screen display, and the input person hits the space key and is confirmed as it is, it is basically the same as the case of general input, and tie is provisionally input as a continuation of the text Since this is selected from the virtual input screen by pressing the shift key, one more key is pressed down compared to the case of general input.

In the case of united, the three spellings of united, vnted, and united are input simultaneously, and only united that is established as English is provisionally input as the text, and if the input person hits the space key, it is fixed as it is. Same as general input.

In the case of States, nine spellings of states, xstates, zstates, statex, statez, xstatex, xstatez, zstatex, and zstatez are entered at the same time, and only those states that are established as English are provisionally entered as the text. If you hit the space key, it is fixed as it is, so it is the same as in the case of general input.

In the case of in, three spellings of in, yn, and hn are input at the same time. Among them, only in that is established as English is provisionally input as the text, and if the input person hits the space key, it is fixed as it is. Basically the same as in the case of general input.

In the case of perfect, three spells of perfect, perfectek, and perfecteq are simultaneously input, and only the perfect that is established as English is temporarily input as the text, and if the input person hits the space key, it is fixed as it is. Same as general input.

In the case of Union, nine spellings of union, yion, hion, unyon, unhon, ynyon, ynhon, hnyon, hnhon are entered at the same time, and only the union that is established as English is provisionally entered as the text. If you hit the space key, it will be fixed as it is, so it is basically the same as the case of general input.

In the case of establish, there are 3 types of spellings for es, 3 types for tabli, 3 types for s, and 3 types for h. Is done.

Writing all of these 81 spellings is extremely cumbersome.

Therefore, first, the number of words including the tabl part is searched by using documents including documents related to the US Constitution.

As a result, there are limited words such as table, establish, notable, comfortable, profitable, suiteable, etc. that exist as words including the part of tabl. When further expanding to tabli, tabley, tablelh, tablh is searched. There are no words to include, only words that include tabli are Establish, and words that include table are limited to notably, comfortably, profitable, and suiteable.

These words other than establish do not meet the condition of having any spelling of es, ex, ez at the beginning, and at the end, sh, sy, si, xh, xy, xi, zh, zy, Does not meet the condition of having any spelling of zi.

Therefore, when the establish is input by the method of the present invention, there are 81 possible spellings, but only the establish that is actually established as English is provisionally input as the text, and the input person can enter the space key. If you press, it will be confirmed as it is.

In the case of justice, there are 2 types of spellings for j, 3 types for u, 3 types for s, 3 types for i, and 3 types for c. .

Writing all these 162 spellings is even more cumbersome.

Therefore, the spelling of justice is broken down into jg-uvw-sxz-t-hiy-ckq-e for each key responsible for the input, and the first jg-uvw-sxz-t is input. Verify whether a word can be identified.

When the four elements jg-uvw-sxz-t are combined, 18 combinations of 2 × 3 × 3 × 1 are established.

They are 18 types of spellings: just, juxt, juzt, jvst, jvxt, jvzt, jwst, jwxt, jwzt, gust, uxt, guzt, gvst, gvxt, gvzt, gwst, gwxt, gwzt.

Of these 18 types of spelling that are input simultaneously, only the words just, juxta (a connected form meaning close), and just (taste, taste) are established as English.

Of these three spellings, juxta is entered with hi instead of a after t, so it disappears at this stage, and gust requests ave as the next three-letter, and gustave This is also disqualified because there can be no spelling other than to be (boy's name).

In this way, justice is actually temporarily input as the text, and if the input person hits the space key, it is fixed as it is, so that it is the same as in general input.

From the above, it has become clear that this 9-key input key allows you to input English text in a form that is not much different from a normal personal computer.

However, since this situation is based on the complementarity of the English word spelling of the English letter mother, it is very large when inputting katakana spelled Japanese words that do not have such complementarity. Difficulties arise.

For example, if the spelling of (Mrs.) Yoshiko Ishii is entered all at once as it is, 3 × 3 × 3 × 3 × 3 × 3 × 3 × 3 × 3 × 3 = 59049 spellings appear, It is expected that a considerable number of spellings will actually exist in Japanese.

Therefore, in order to avoid such difficulties, when inputting foreign words, particularly foreign words other than Indo-European languages, when these keys such as hi, sxz, uvw, ckq are depressed, Appropriately, in the middle of the input, input candidate characters or words displayed on the display screen are determined.

For example, when inputting the spelling (Mrs.) Yoshiko Ishii, when yos is entered, nine spellings are displayed on the display screen at the continuation of the text or at a different position. At this stage, the spelling to be selected is determined according to a predetermined procedure.

Next, if you enter hi, ko, is, hi, i and enter them, you can enter only these spellings. Depressing the key once, a total of 2 times, will be repeated 6 extra times.

In other words, in this case, it is necessary to press the key six times more times than the general personal computer for the input of 12 characters, but such a scene does not appear so much.
"Solving the sign input problem"

The next problem is that, in both Japanese and English input of the present invention, the 9 keys do not include symbols such as punctuation marks, parentheses, commas, and periods.

In this regard, the present invention solves this problem by setting a virtual code input keyboard on the display of the screen, as in the case of selection and determination of input candidate characters.

That is, a necessary code is input by searching for a required key on a virtual code input keyboard called up on the display of the screen, and depressing an actual key at a corresponding position.

This problem can be explained more specifically by comparison with the conventional method as follows.

As mentioned earlier as the presentation of the problem to be solved by the invention, the difficulty of code input in the 9-key type or conventional ten-key type portable input terminal has already been found in the alphabetic alphabet that represents the Japanese alphabet and the Japanese alphabet. Alternatively, the keyboard filled with the 26-letter alphabet for entering English text does not have enough room for the sign, and inevitably displays the sign on the screen display, The operation of searching with the cursor, that is, the keyboard operation in character input, is different and somewhat unstable, and generally requires a method with a large number of operations.

In this regard, the present invention sets a code keyboard, i.e., a virtual keyboard for exclusively inputting a code, apart from a character input keyboard such as a Japanese input keyboard or an English input keyboard, and depresses a separate keyboard switching key, By entering this code keyboard, the above problem is solved.

In this case, since alphabet letters, hiragana letters, numbers, etc. are already written on the actual hard keys, the codes set here cannot be written on the actual hard keys. Similar to the selection and determination of candidate characters, a virtual code keyboard is displayed on the screen display.

In the case of a general portable terminal, a method is adopted in which the sign displayed on the display of this screen is determined by tracing with a cursor. In this method, the key is directly input as in the case of character input. As compared with the method of inputting by pressing down, the input operation is unstable, and the number of times of pressing the jog key or the like until reaching the code displayed on the display of the screen is usually considerably increased.

Therefore, in the present invention, the code keyboard displayed on the display of this screen is made to correspond to the actual keyboard, and the position corresponding to the required key in the code keyboard displayed on the display of this screen is set. By depressing a certain actual key, a necessary key is set to be inputted.

According to the present invention, it is possible to select and input a necessary code from nine codes in total of 3 rows and 3 columns by simply depressing the keyboard switching key once while inputting Japanese, English or numbers. By continuously depressing the key N times, it becomes possible to select nine N times codes, and the code input operation is greatly streamlined.

In the above case, it is important to note that when selecting candidate characters while entering English, Japanese, etc., the actual key corresponding to the virtual keyboard after pressing the shift key at the initial stage. There is an operation of pressing down the key, and when the target is not found at this stage, the keyboard switching key is pressed down for the first time, so the operation method is different from the code input that is entered by pressing the keyboard switching key immediately during character input. There is no confusion between the two.

The above is a skeleton part of the solution of the code input problem in the present invention. The content thereof will be described in more detail as follows.

In the 3-row 3-column 9-key portable input terminal according to the present invention, the input of each character is determined in a scene where code input is required in each of Japanese input, English input, and numeric input. After that, the keyboard switch key is continuously depressed for a predetermined number of times, so that a necessary code keyboard is called according to the number of depressions.

First, in the 3-row, 3-column 9-key portable input terminal according to the present invention, the contents of the sign keyboard that is entered by depressing the keyboard switching key once during the Japanese sentence input are basically used only for the Japanese sentence input. This is referred to as a Japanese-language code basic keyboard, and its contents are (reading marks). (Punctuation), “”, “”, 〃, ゝ, *, # are assumed to consist of nine symbols.

As shown in FIG. 8, this Japanese code basic keyboard is in the first row and first column of the 9 keys of 3 rows and 3 columns, (reading marks), and in the second column. (Punctuation mark), in the third column, "" in the second row and first column, "" in the second column, 〃 in the third column, * in the third row and first column, ゝ in the second column, third Set # in the column.

In the numeric input and numeric code input in the 3-row 3-column 9-key portable input terminal according to the present invention, it is difficult to input only 9 numbers with the 3-row 3-column 9 key used for character input. Therefore, in the present invention, as shown in FIG. 5, a key used as a shift key in the case of character input is input, and in the case of numerical input, the number 0 is input. This is because the key press is the input that is confirmed as it is, so in this case there is no need to set the shift key, and after entering the dimension of code input by pressing the keyboard switch key while entering numbers, The virtual keyboard is a 9-key type with 3 rows and 3 columns, and the function of the shift key is restored.

In the 9-key type portable input terminal of 3 rows and 3 columns, the content of the code keyboard that is entered by depressing the keyboard switch key once during the numeric input using the above keyboard, that is, the number basic code keyboard according to the present invention, f (x), f ′ (x), ∴, ∵, ∫, ∬, ∂, *, #, are composed of 9 codes, as shown in FIG. F (x) in the first row, first column, f ′ (x) in the second column, ∴ in the third column, ∫ in the second row, first column, ∬ in the second column, third Set ∵ in the column, * in the third row and first column, ∂ in the second column, and # in the third column.

In the 3-row, 3-column 9-key portable input terminal according to the present invention, the keyboard switching key is depressed twice in succession in a situation where code input is required in both cases of Japanese text input and numeric input. Depress the keyboard four times or more from the code keyboard called by the keyboard to the code keyboard called, and three or more times from the code keyboard called by pressing the keyboard switch key once during English input The contents of the keyboard up to the code keyboard called by pressing down are the same regardless of the input type.

In the above, in the process of inputting Japanese sentences and entering numbers, in each case, a code keyboard that is entered by continuously depressing the keyboard switching key twice, and a keyboard that is called by depressing the keyboard switching key once during English input In other words, the contents of the first keyboard according to the present invention are composed of the same basic English codes and Internet-related codes in all of Japanese input, English input, and numeric input.

The contents of the first keyboard referred to in the present invention are specifically,, (comma),. (Period),: (colon),; (semicolon), / (slash),-(hyphen),? (question mark)! @! (Exclamation mark), a total of 9 codes, and as shown in FIG. 10, in the first row and first column of the 9th key of 3 rows and 3 columns, (comma) in the second column. (Period) in the third column, / (slash), second row, first column: (colon), second column; (semicolon), third column-(hyphen), third In row 1st column? (Question mark), @ in the second column, and in the third column! Set (exclamation point).

In the above process, in the process of inputting Japanese text and entering numbers, in each case, it is called by pressing down the keyboard switching key three times continuously, and by pressing down the keyboard switching key twice during English text input. The contents of the keyboard, that is, the second keyboard of the code according to the present invention, are mainly the same code centered on the parenthesis code in the case of Japanese input, English input, and numeric input.

The contents of the second key of the code according to the present invention are specifically, ‘’, “”, (), {}, [], <>,

, << >>, · (Nakagro), as shown in Fig. 11, as shown in Fig. 11, the first row and the first column of the 9th key of 3 rows and 3 columns, "", the second column "", () In the third column, {} in the second row, first column, [] in the second column, <> in the third column, <> in the third row, first column

, << >> in the second column, and (Nakagro) in the third column.

In the above process, in the process of inputting Japanese sentences and entering numbers, in each case, it is called by pressing down the keyboard switching key four times continuously, and by pressing the keyboard switching key three times continuously during English input. The contents of the keyboard, that is, the second keyboard of the code according to the present invention, are mainly the same code centered on the parenthesis code in the case of Japanese input, English input, and numeric input.

Specifically, the contents of the third keyboard of the code referred to in the present invention are nine codes of +, −, ±, ×, ÷, ≡, =, ≒, ≠, as shown in FIG. 9 rows of 3 rows and 3 columns, the first row, first column +, second column-, third column ±, second row first column x, second column ÷, Set ≡ in the third column, = in the third row and first column, ≒ in the second column, and ≠ in the third column.

Code keyboard called in all 3 rows and 3 columns 9-key portable input terminal, ie Japanese basic code keyboard and numeric input basic keyboard, Japanese input from the first keyboard to the third keyboard, English input, A code keyboard that is common to all three types of numeric input is set so that when it is called, it is displayed on the display screen in a form corresponding to a 9-key keyboard with 3 rows and 3 columns. To do.

In general, according to the present invention, even on a keyboard having a form different from that of an input keyboard of 3 rows and 3 columns, or a keyboard having a larger or smaller number of keys, each code keyboard is called. At this time, it is possible to set the display to be displayed on the display screen in a form corresponding to each actual keyboard.

In the above, the code keyboard displayed on the display screen is translucent and covers the input screen, or is opaque and placed on any appropriate part of the input screen (for example, at the bottom of the screen). Set to be displayed on the screen.

In general, according to the present invention, each of the code keyboards corresponds to each keyboard, even on a keyboard having a form different from that of an input keyboard of 3 rows and 3 columns, or a keyboard having more or less keys. Set to be displayed on the screen of the display, either translucent and covering the input screen, or opaque and placed on any suitable part of the input screen (eg at the bottom of the screen) I was able to do it.

In the above, setting is made so that when a key on the actual keyboard at a position corresponding to the position of the code currently required for input is pressed among the various codes displayed on the screen, the code is input. To do.

In general, according to the present invention, even in a keyboard having a form different from that of an input keyboard of 3 rows and 3 columns, or a keyboard having a larger or smaller number of keys, among the various codes displayed on the screen, When a key on the actual keyboard at a position corresponding to the position of the code required as an input object is pressed, the code can be set to be input.

In the above, the key on the actual keyboard at the position corresponding to the position of the code is depressed, and the setting is made so that the setting during the original input is immediately restored when the code is input.

In general, according to the present invention, even in a keyboard having a form different from that of an input keyboard of 3 rows and 3 columns, or a keyboard having a larger number of keys or a smaller number of keys, an actual position corresponding to the position of the code It is now possible to set the keyboard so that it returns to the original setting as soon as the key is entered by depressing a key on the keyboard.

"For Japanese input"

According to the present invention as described above, in the case of Japanese text input, an input close to a combination of 9 keys in 3 rows and 3 columns and 26 character input keys in the case of a personal computer and a considerable number of other code keys. It became possible to have functions.

More specifically, for example, in the case of a personal computer using a so-called qwerty board in which 26 characters of ordinary English characters are set when inputting “in the case of Japanese effect input” in Hiragana, , A, t, u, m, e, i, n, o, k, o, u, k, aw, a, b, u, n, n, n, y, u, u, r, y, "o, k, u, n, o, b, a, a, i". This sentence is input by the number of characters delimited by the punctuation marks, that is, by pressing the key 35 degrees.

On the other hand, in the case of a keyboard having nine keys of 3 rows and 3 columns according to the present invention when inputting “Hiragana input” and “Hiragana input” in this case, “h, a, t, u, m, e, consonant notes i, n, o, k, o, consonant notes, u, k, a w2, a, b, u, consonant notes, nose notes, n, y, u, r, y, o, k, u, n, o, b, a, consonant note, a, consonant note i ”, where the key is pressed once to call w for the number of characters delimited by punctuation. With the addition, this sentence is entered by pressing the key at 39 degrees.

In other words, the mobile input terminal using 9 keys of 3 rows and 3 columns according to the present invention is a little more than 10% in a calculation of 39 ÷ 35 = 1.143 for a general personal computer having three times or more keys. The same content can be input by increasing the number of key presses.

In the case of the present invention, both the consonant keyboard and the vowel keyboard are arranged in the order of the Japanese syllabary order, so at least for the Japanese, there is more resistance than when using the so-called qwerty board. It is easy to approach without it, and nerve fatigue during input is reduced.
"For English input"

The first feature of the English input of the present invention is that it is only necessary to grasp the location of 17 alphabets or combinations of alphabets with respect to the alphabet, so it is easier to learn the input method compared to normal alphabet input. Since all English letter mothers can be called up by switching the keyboard once, the input speed is much faster than in the case of a normal numeric keypad.

More specifically, for example, in the case of a personal computer using a so-called qwerty board in which 26 letters of ordinary English letters are set when inputting the letters “the effect of the invention in the case of English input” in alphabets. If the capitalization of English E is added except for the space key input common to both, this sentence is input by adding 1 to the number of letters 46 and pressing the key down 47 degrees.

On the other hand, in the case of a 9-key keyboard having 9 keys of 3 rows and 3 columns according to the present invention, when inputting “the effect of the invention in the case of English input” in alphabet, If the number of key presses required to enter a letter is shown in parentheses after the letter, and there is no reference to the input candidate keyboard,
“T (1) h (1) e (1) e (1) f (2) f (2) e (1) c (2) t (1) o (1) f (2)
t (1) h (1) e (1) i (1) n (1) v (1) e (1) n (1) t (1) i (1) o (1) n (1) i ( 1) n (1) t (1) h (1) e (1) c (2) a (1) s (1) e (1) o (1) f (2) E (1) n (1) g (2) l (2) i (1) s (1) h (1) i (1) n (1) p (2) u (1) t (1) " This sentence is input by pressing down.

Actually, the spelling of effeqt, effekt, and case is not established for the effect, and the alternative spelling is not established as described in the case of the invention. In case of English, the spelling of Enjl that replaces Engl is not established, and the spelling of Engl is established, and then ish continues, and in the case of input, it replaces inp. Since there is no spelling of hnp or ynp and no spelling of vt or wt follows inp, these words are input without any reference to the input candidate keyboard. When selecting one word from three words, type and tie, the shift key can be pressed once more Remaining, by depressing the maximum total of 56 degrees of the key, this sentence is input.

Here, there is a capital letter in the case of English, and this is input while pressing the shift key in the case of a normal personal computer, so it is necessary to press the key twice. However, in the case of the present invention, the keyboard switch key is pushed down to enter the English input back keyboard after that, and then the large letter is pushed down there. Two extra key depressions are required, and the total number of key depressions is a maximum of 58 degrees.

This is slightly higher than 123% of 47 degrees for a normal personal computer. In the case of a nine-key keyboard having nine keys of 3 rows and 3 columns according to the present invention, the number of depressions is about 20% higher than that for a normal personal computer. The same contents can be input with.

This ratio is defined by the ratio of the appearance rate in the English sentence of the alphabet letter set on the English input table keyboard according to the present invention and the alphabet letter set on the English input back keyboard. Details of this point As for, the data will be shown in detail in the explanation of the principle of English input, but the ratios mentioned here are almost the same when verified with a larger amount of data.

In comparison with the input method of the conventional portable terminal, the superiority of the present invention in English input is clearer than that in the case of Japanese input, but that point is only one conventional input, as will be described later. In the method, there was no commonality in operation between Japanese input based on the Japanese syllabary and the English input method in which 3 to 4 alphabetic letters were set for one key. In the case of the present invention, all the keys on the same keyboard are input by pressing the key once. Therefore, it is pointed out that Japanese input and English input have a certain commonality in operation. Want to.

The above-mentioned commonality is expected to significantly reduce psychological resistance when Japanese inputs English and Westerners input Japanese, compared to the conventional method.
"Sign input"

The situation of code input by the code keyboard can be summarized as follows.

First, in Japanese input keyboard and numeric input keyboard, both Japanese basic code keyboard and numeric basic code keyboard, which are called by pressing down the keyboard switching key once after entering the character input, provide 9 codes and displayed on the screen When a key on an actual keyboard at a position corresponding to the position of the code currently required for input is pressed among the various codes, the code is input.

That is, in the Japanese basic code keyboard and the numeric basic code keyboard, nine codes are input by pressing the key twice.

Next, in the Japanese input keyboard, the numeric input keyboard, and the English input keyboard, it is called by pressing down the keyboard switching key twice in succession, and in the English input keyboard, the code 1st keyboard called by pressing down the keyboard switching key once is also called. Also, when nine codes are provided and a key on the actual keyboard at a position corresponding to the position of the code currently required for input is pressed among the various codes displayed on the screen, the code is displayed. Entered.

That is, on the code first keyboard, nine codes are input by depressing the key three times.

Next, in the Japanese input keyboard, the numeric input keyboard, and the English input keyboard, it is called by pressing down the keyboard switching key three times in succession, and in the English input keyboard, it is called by pressing down the keyboard switching key twice in succession. The 2 keyboard also provides 9 codes, and when you press a key on the actual keyboard at a position corresponding to the position of the code currently required for input among the codes displayed on the screen, The code is input.

That is, on the code second keyboard, nine codes are input by pressing the key four times.

Next, in the Japanese input keyboard, the numeric input keyboard, and the English input keyboard, it is called by pressing down the keyboard switching key four times in succession, and in the English input keyboard, it is called by pressing down the keyboard switching key three times in succession. The 2 keyboard also provides 9 codes, and when you press a key on the actual keyboard at a position corresponding to the position of the code currently required for input among the codes displayed on the screen, The code is input.

That is, on the code third keyboard, nine codes are input by pressing the key five times.

Thus, in the Japanese input keyboard and number input keyboard of the present invention, nine basic codes necessary for Japanese sentence input and number input are input by pressing the key twice, and Japanese input is performed by pressing the key three times. Nine more symbols required for numeric input and 4 key presses, 9 additional codes required for Japanese input and numeric input, 5 key presses for Japanese input and numbers Nine more codes necessary for input are input.

That is, 36 codes are input with a total of 126 degrees of key presses, as in the formula 9 × (2 + 3 + 4 + 5) = 126, and one code is input with a key press of an average of 3.5 degrees. .

On the other hand, the code input in the conventional portable input terminal is, as a typical example, a cellular phone, once entered code input, and again searched the screen on the display where the code of interest is arranged, and there were several cursors there. It requires a cumbersome procedure to reach the target code by operating the keys.

Now, suppose that the code call screen of the mobile phone is in the form of 4 vertical and 10 horizontal, until reaching the required code with the cursor, and further pressing the enter key to enter this, When the average number of times the cursor and the enter key are pressed is obtained, it can be calculated by the following concept.

In other words, the leftmost and topmost signs on the screen can be entered by pressing the enter key once. To enter the right and bottom keys, move the cursor once and then press the enter key once. It is necessary to press down, the total number of presses will be 2 degrees, and after moving the cursor twice to enter the right two keys and the two lower keys from the leftmost and topmost signs on the screen It is necessary to depress the enter key once, the total number of depressing is 3 degrees, and the cursor is 3 to input the right key and the 3 lower key from the leftmost and topmost signs of the screen. It is necessary to depress the enter key once after moving it, and the total number of depressing times will be 4 degrees

In the above case, for example, to input a key on the line connecting the right key and the lower three keys from the leftmost and uppermost codes, the right key and the three lower keys from the uppermost code. As in the case of the key, the total number of times the cursor key is pressed and the number of times the enter key is pressed is 4 degrees.

In order to input one key to the right key from the key on the line connecting the three right keys and the three lower keys from the uppermost code in the above case, it is necessary to move the cursor once more. The sum of the number of times the cursor key is pressed and the number of times the enter key is pressed is 5 degrees.

In the above case, it is necessary to move the cursor one more time to input the two right keys from the key on the line connecting the three right keys and the three lower keys from the topmost sign. The sum of the number of times the cursor key is pressed and the number of times the enter key is pressed is 5 degrees.

By repeating this process, the key on the line connecting the 3 right keys and the 3 lower keys from the topmost sign leads to the input of the 6 right keys, that is, the rightmost end of the keyboard, the topmost key, The sum of the number of times the cursor key is pressed and the number of times the decision key is pressed is 10 degrees.

From here, the number of keys to be depressed gradually decreases, and for the input of the remaining three keys, the total of the number of times the cursor key is depressed and the number of times the decision key is depressed is 11 degrees, and the remaining two keys The total of the number of times the cursor key is pressed and the number of times that the enter key is pressed is 12 degrees, and the number of times the cursor key is pressed and the number of times the enter key is pressed to input the rightmost and bottommost keys of the last keyboard. The total is 13 degrees.

As a result, the total number of key presses on this keyboard is 1, 2, 3, 4 times 4, 5 times 4, 6 times 4, 7 times 4, 8 times 4, 9 times 4, 10 times 4, 11 times 3 , 12 times 2 and 13 times 1 is the total number, that is, 272 degrees.

The total number of key depressions of 272 degrees divided by 40, which is the total number of keys, is 6.8, which is the average key required for calling 40 codes in a general mobile phone. The number of depressions.

Compared to the case where 36 codes are input by pressing the key with an average of 3.5 degrees, which are Japanese sentence codes and numeric codes in the present invention, it can be said that the present invention is simpler.

Comparing this with the case of the English code in the present invention, in the English code in the present invention, the first code keyboard to be called is the code first keyboard, which is called the Japanese code and numeric code call in the present invention. In comparison, although the number of key presses is shifted one by one when calling the same code keyboard, the number of key presses for calling one key is the same as in the case of numeric input or Japanese text input.

That is, in the English code according to the present invention, 27 codes are input by pressing the key of a total of 81 degrees as in the formula of 9 × (2 + 3 + 4) = 81, and one code is an average of 3 degrees keys. If the fourth key is set by pressing the key down, and 36 codes are input by pressing the key 126 times in total, as shown in the formula 9 × (2 + 3 + 4 + 5) = 126, The code is input by pressing the key with an average of 3.5 degrees.

In the case of an English code, if the code 5th keyboard is set, 45 codes are input by pressing the key 180 degrees in total, as in the formula 9 × (2 + 3 + 4 + 5 + 6) = 180. Is input by pressing the key four times on average, and even in this case, it is superior to a general portable terminal.

And in actual use, the present invention is the best because the keyboard with these nine symbols is displayed in the same form as the actual keyboard on the display screen. If you are proficient, you will be able to grasp the location of the key intuitively, and you will be able to input very quickly and steadily.

The above is a comparison between the present invention and a conventional general portable terminal.

The code input system according to the present invention further has an advantage over the conventional general personal computer.

First, every time a new code input key is called by pressing down the keyboard switch key, the 3 rows and 3 columns key is displayed on the display screen, so the necessary code on the keyboard consisting of about 48 keys. This means that the input person's psychological fatigue can be reduced compared to the case of a personal computer that needs to search for.

Further, in the present invention, by pressing down the keyboard switching key five times or more, nine codes can be called for each depression, so when many kinds of codes are required, the present invention It can be said that this method is superior to the case of a general personal computer.
"When entering candidate characters"

To reiterate, a technology that has been remarkably developed in small mobile terminals, especially mobile phones, has a method of selecting and presenting candidate characters by predictive conversion, guess conversion, and greatly increasing the input operations of mobile input terminals that are inherently small and constrained In general, in the case of candidate character input, it is generally said that a mobile input terminal, typically a mobile phone, has succeeded in providing candidate characters more thoroughly than a personal computer. I can say that.

This is because the input operation of a portable input terminal, typically a mobile phone, is extremely difficult compared to a personal computer, and it can be evaluated that it has been developed as a means for reducing the difficulty.

However, in the actual input of many candidate characters provided in detail, there is a procedure for searching for a plurality of candidate characters displayed on the screen, and reaching this candidate character by depressing the cursor key several times. In addition, if the required character is not found in the initially provided list of candidate characters, one candidate character is provided for each additional cursor key depression, Since it is necessary to search for necessary candidate characters, the procedure becomes extremely cumbersome if the necessary characters are not found in the list of candidate characters provided first.

In this method, not only keyboard input and different key operations are required, but it is also necessary to watch the display while continuously pressing the jog key until the cursor reaches the target lexical, and it is necessary to worry about nerve fatigue during input It is a factor.

In the case of the general method, even if the candidate character can be input the earliest, the candidate is selected by pressing the cursor once, and this is confirmed by pressing the enter key. In the present invention, the display screen is displayed. The candidate characters displayed in are placed in a form corresponding to the actual keyboard, and the candidate characters are input by pressing down the keys of the actual keyboard corresponding to the required candidate characters. Thus, any of nine candidate characters can be input by pressing the key twice.

Furthermore, if the candidate characters are not displayed on the first display screen, nine new candidate characters can be displayed by depressing the keyboard switch key again in the present invention. There are differences depending on the mechanism, but in the normal method, in order to find the same nine candidate characters, you can finally find one new candidate character by moving the cursor to the next candidate after the last candidate on the first screen Therefore, it is generally necessary to press down a key at least once and at most about 9 degrees.

In the present invention, it is possible to present and input a set of nine new candidate characters for each key depression by repeating the same procedure of continuously depressing the keyboard switching key. Thus, the superiority of the present invention increases as the candidate characters are not easily found.

In the case of English input of the present invention, since a plurality of characters are assigned to one hard key, a definitive result cannot be obtained by one input, and an appropriate one of several candidate words can be selected. In this case, it is necessary to display a plurality of candidate words on the display screen. In this case, by adopting this method, a plurality of candidate words are displayed. It is easy to select a necessary word from among the candidate words.

The input of candidate characters as described above is an area in which the portable input terminal has an advantage over the personal computer. In the present invention, improvements are made while taking advantage of the advantages of both the conventional personal computer and the conventional portable input terminal. We succeeded in presenting a superior new input method.
"Overall effect"

The present invention has succeeded in raising the input level of the conventional portable input terminal over all aspects of Japanese input, English input, code input, and candidate character input. In all these aspects, if you prepare multiple keys and call them by automatic or manual switching of the keys, especially when you cannot display them on the actual keyboard as in the case of code input and candidate character input By displaying it as a virtual keyboard on the display screen, it is possible to input them easily based on the correspondence between the on-screen keyboard and the actual keyboard, and from these four inputs It was a success in creating a certain degree of harmony between methods.

In the case of personal computer input, the lack of harmony between portable input terminals, which is substantially realized by the presence of a large number of keys, that is, Japanese input using the Japanese syllabary method. A portable input terminal with three different input methods: English input that assigns 3 to 4 alphabetic letters to one key, code input by moving the cursor on the display screen, and candidate character input A kind of instability in this case was eliminated by the present invention.

As described above, the present invention greatly increases the input speed of a 9-key input terminal having 9 keys of 3 rows and 3 columns, and succeeds in obtaining a more stable and almost operability similar to a current personal computer. did.
"Some clarifications about the invention"

In the present invention, regarding the keyboard of 3 rows and 3 columns, the main subject is what character and number input functions are given to the nine key portions as a whole.

In the case of Japanese text input, the present invention intends to guarantee an input function equivalent to that of a large keyboard even for a small keyboard by a method of automatic alternation of consonant keys and vowel keys and a rational key arrangement. It is.

In the case of inputting English sentences, the present invention is designed for a small keyboard by switching two keys with a keyboard switching key and collecting characters having a high frequency of appearance on the first key of the two keys. However, it tries to guarantee the same input function as a large keyboard.

The present invention also provides a keyboard with higher functions and operability by utilizing a characteristic of English spelling and arranging a plurality of letters for each key assigned to the two keys.

The present invention aims at advanced design of Japanese input and advanced design of English input method and code input method corresponding to it, and the target design such as cursor movement, screen scrolling or input determination conforms to the current method. Use a device such as a jog dial or cross key.
"Principle explanation of English input problem"

As already mentioned, the biggest problem in English input in small input keyboards such as mobile phones that are generally used at present is that three letters are assigned to one key as in the case of abc, It is necessary to press the key three to four times to input one character, up to the one assigned four characters as in the case of pqrs.

Furthermore, there is a problem of an input rhythm error resulting from a mixture of three key depressions and four key depressions.

The basic cause of the difficulty common to English input methods in such small-sized input terminals as mobile phones is due to the limitation that 26 alphabets must be arranged on a maximum of 12 hard keys in a so-called numeric keypad. Yes.

However, the relationship of the 26 letters of the alphabet to the spelling of the English word is not uniform in relation to its history as a letter.

In other words, among the 26 letters of the alphabet, g and j, c and k and q, s and x and z, u and v and w and h and i and y are 14 sets of consonant letters in the relationship to the spelling. In principle, they are complementary to each other.

For example, in the spelling of an arbitrary English word containing k or q, there is no word in which the part where k is used is replaced with q in principle, and conversely, the word where k is used in the part where q is used Does not exist.

Thus, if the word “key” exists, the word “qey” does not exist, and if the word “question” exists, the word “question” does not exist.

This is because q + u is treated as a consonant equivalent to k in the alphabet notation in the Indo-European system including, for example, French and German.

Although not so clear, a similar relationship exists between c and k and q, between g and j, between s and x and z, between u and v and w, and between h and i and y. In principle, this is also true for 5 sets of 14 characters.
“Between c and k”

As a result of contrasting all words beginning with k in Kodansha Packs English-Japanese Dictionary (1992, 68000 items included) with all words starting with c in Large Dictionary Research Leaders English-Japanese Dictionary (1984, 260,000 items included) Even if rewritten as c, 39 words were established.

They are written in alphabetical order as follows:

Kaaba, kabob, kaftan, kalends, kapok, karakul, karat, Kasbah, Kelt, Khi, klaxon, kreptmania, kola, Kopek, Korea, kraal, Kur, k, k, k, k, k, k, k KY, kart, Kent, kid, kinder, kit, kit, kite, klan, kook, kosher, craft, krone.

Among the above words, 18 words from Kaaba to Kurd represent the same entity regardless of whether c or k is used, 9 words from KB to KY are abbreviations, and 12 words from kart to krone A word that refers to a different entity.

Among the above words, one proper noun, that is, a word that can be distinguished from another word even if it is rewritten by starting with a capital letter is one for a word starting with c (Cid → kid) and one for a word starting with k (clan → klan) There are two in total.

Therefore, it is really difficult to input unless it is allowed to express the same entity like Kaaba and Caaba in two ways, such as an abbreviation that should be input one by one. Means 10 words obtained by subtracting 2 words from 12 words from kart to krone.

As can be seen from the above list, most of these words are vocabularies that are not frequently used every day except proper names.

Therefore, there are a small number of words that are the target of the operation of assigning the registered word and the input word, and the possibility of the appearance of the situation where these words are the target of input is not high.

When these words need to be input, for example, two words, kart and cart, and krone and cone, are displayed on the screen, and one of them is selected.

The next problem is when c and k appear in words.

Actually, k is a consonant of r, l, c, s, n, etc. before it, such as work, talk, back, clark, ask, monk, link, lac, drank, etc. Appearing at the end of the word, or appearing at the end of the word after overlapping vowels such as “talk”, “seek”, “ook”, “book”, “hook”, etc. Usually appears at the end of the word, otherwise it is a word in a spelling combination with a specific letter such as ake, ake, ike, uke, etc., such as make, take, wake, like, duke, etc. Appears inside.

On the other hand, c usually appears in the word except for the beginning of the word, and when it appears at the end of the word, it follows a specific vowel in the form of picnic, critical, programmatic or maniac, manic, etc. In these cases, there is no word in which c is rewritten to k.

Also, in contrast to the case where k appears in a spelling of a combination with a specific letter such as ake, ake, ike, uke, etc., such as make, take, wake, like, duke, etc., ace, Considering the case of each of the spells of ice, ucce, ace, and ace, fake (fake), rake, and rake in spellings that include ace, such as trace, place, race, face, pace, trace race, and menace. (Rake) is found only when there is a duke (duke) corresponding to duce (Italian chief) in the case of production and duce containing uce, and notice, practice, and price in case of containing ice , Rice, license, service, off ce, reticence, choice, piece of the case, including the ece, receive, necessary, perceive, recent, process of the case, including the oce, proceed, this case is not seen at all in the case of such ocean.

Thus, c and k are generally complementary in the word, and are very rarely confused in relation to the above exceptions and word form changes such as like and slice (louse). It only happens.

As described above, a keyboard in which c and k belong to one hard key can realize the same function in most cases as a keyboard in which one hard key is assigned to each of c and k.
“Between c and q”

As a result of contrasting all words beginning with q in the Kodansha Packs English-Japanese Dictionary (recorded in 1992, 68000 items) with all words starting with c in the Large Dictionary Researchers Leaders English-Japanese Dictionary (1984, recorded in 260,000 items) Even if rewritten as c, 4 words were established.

These were only four abbreviations, QB, qr, qv, and Que, in alphabetical order.

In the above words, “Que” is an abbreviation of the uppercase proper noun “Quebec”, and corresponds to the common noun “cue” and can be easily distinguished.

The next problem is when c and q appear in the word.

In this case, q usually appears in the form of having q behind it and following it with another vowel, such as que, qua, cuo, qui, in both cases. Therefore, q does not appear at the end of the word.

On the other hand, c has only the same spelling in very few Latin words such as evacuate, cuisine, quirass, conspicuous, etc., and in these words, c is replaced with q. There are no words.

Therefore, a keyboard in which c and q belong to one hard key can realize the same function in most cases as a keyboard in which one hard key is assigned to each of c and q.
“Between k and q”

As a result of comparing all the words that start with q in the Kodansha Packs English-Japanese Dictionary (recorded in 1992, 68000 items) with all the words that start with k in the Large Dictionary Research Leaders English-Japanese Dictionary (1984, recorded in 260,000 items), this q Even if rewritten to k, only one word in the case of Qatar and Katar was established.

In this case, both Qata and Katar represent Qatar on the Arabian Peninsula, and both of the two notations are valid.

The next problem is when k and q appear in a word.

Actually, as mentioned above, except that k appears at the beginning of the word, r, l, c, and so on are preceded by a word such as work, talk, back, clark, ask, monk, link, lac, rank, etc. Usually, it appears at the end of the word with consonants such as s, n, etc., otherwise, the specification of ake, ake, ike, uke, etc., such as make, take, wake, like, duke, etc. It appears in the spelling of a combination with the letter of the name, or after vowels are overlaid such as “talk”, “seek”, “ook”, “book”, “hook”, etc., or as a modification thereof, such as “seek”, “speak”, etc.

On the other hand, q appears in the form of having q behind it and following another vowel behind it like que, qua, cuo, qui, both in the beginning and in the word. It is customary and has a completely different form from the above word containing k.

Therefore, a keyboard in which k and q belong to one hard key can realize substantially the same function as a keyboard in which one hard key is assigned to each of k and q.
“Between g and j”

As a result of contrasting all words beginning with j in the Kodansha Packs English-Japanese Dictionary (recorded in 1992, 68000 items) with all words starting in g in the Large Dictionary Research Leaders English-Japanese Dictionary (1984, recorded 260,000 items), this j Even if rewritten to g, 35 words were formed.

They are written in alphabetical order as follows:
Jag, jaile, Jal, jam, James, jangle, jape, jar, Jas, jaunt, jay, jeep, Jer, jerry, jest, jet, jib, jig, jiggle, jill, jiet, jink, jibj joggle, jolly, josh, jot, Joy, jumbo, Jun, junk, just, jut.

Among the above 36 words, five proper words (Jal, James, Jas, Jer, Jun) that start with proper nouns, that is, words that can be distinguished from each other even if rewritten, start with g There is a total of 6 words (jerry → Gerry) per word.

As can be seen from the above list, most of these words are vocabularies that are not frequently used every day except proper names.

Among these words, words that are used on a daily basis, excluding words that can be distinguished from each other even if they are rewritten by starting with proper nouns, ie, capital letters, for example, j such as job, joy, just, etc. The words starting with g corresponding to the words starting with are each an unusual vocabulary such as gob, goy, guest, etc., and conversely used daily, starting with g such as gape, get, give, got, gun, etc. Each word starting with j corresponding to a word is an extraordinary vocabulary such as shape, jet, jive, and jot.

Therefore, in the case of the beginning of a word, the word registration function displays a frequently used word on the screen as a first candidate to be selected when inputting, and this word is selected unless otherwise selected By doing so, it is possible to realize the same function in most cases by a keyboard in which j and g belong to one hard key and a keyboard in which one hard key is assigned to each of j and g.

The next problem is when g and j appear in the word or at the end of the word.

When j appears in a word, it is customary to follow the spelling of ect in a regular manner, such as subject, object, project, project, project, etc., and replace this j with g. In the case of a few exceptions such as adjust, major, conjure, etc., there is no word in which j is replaced with g.

Furthermore, it can be said that there is no example of j appearing at the end of the original English.

As described above, a keyboard in which g and j belong to one hard key can realize the same function in most cases as a keyboard in which one hard key is assigned to each of g and j.
“Between s and x”

As a result of contrasting all words beginning with x in Kodansha Packs English-Japanese Dictionary (1992, 68000 items included) with all words starting with s in Leader's English-Japanese Dictionary (1984, 260,000 items included) Even if rewritten to x, 12 words were established.

When written in alphabetical order, they are Xe, Xi, Xian, Xiang, Xiangtan, Xing, Xining, XL, Xn, XR, XT, XX.

However, among these words, Xe and Xi are the abbreviations for Greek Xenon and Xi, respectively, and Xian, Xiang, Xiangtan, and Xining are the Romanized names of the Chinese places, respectively. Yes.

In addition, among the above 8 words, there is one (Xing) word that starts with a proper noun, that is, a word that can be distinguished from a word that has been established by rewriting, and the presence or absence of a period or capital letters in the word. There are three cases of XL, Xn, and XT that can be distinguished from the difference between lowercase and lowercase letters.

Therefore, the only words that cannot be identified at the time of input are XR (ex rights) and SR (ie Swissair international abbreviation) and XS (extra small) and SS (Nazi Guard).

Therefore, in the case of the beginning of a word, the word registration function displays on the screen a word suitable for the context at the time of entry as a candidate to be selected, and it is set so that this word is selected unless a selection act is performed. Thus, with the keyboard in which s and x belong to one hard key, it is possible to realize almost the same function as a keyboard in which one hard key is assigned to each of s and x.

The next problem is when s and x appear in words.

In practice, except that x appears at the beginning of the word, in most cases, excact, exaggerate, exalt, examine, example, execution, excise, expert, extend, experience, expose, explicit, explicit, expexp, exp, exp, Like explain, extraordinary, etc., it was placed in front of the word in combination with e placed in front of it, and in fact, ex was considered as one unit and appeared at the beginning of the word. Better.

In such a case, there is no word that is established by replacing x with s.

Other than that, there is a problem when x comes to the end of a box, six, sex, etc., but in any case, there is no word that is established by replacing x with s.

The only problem is that in the case of text and context, x is replaced with s, and the words test and concest hold.

About this point, we guess which is appropriate in text and test, context and contest in the corresponding sentence by assigning it with the word registration function, and present the more likely one in the sentence, and input the one that is not A candidate is displayed on the screen display and selected.

As described above, a keyboard in which x and s belong to one hard key can realize substantially the same function as a keyboard in which one hard key is assigned to each of x and s.
“Between s and z”

As a result of contrasting all words beginning with z in Kodansha Packs English-Japanese Dictionary (recorded in 1992, 68000 items) with all words starting with s in Leader's English-Japanese Dictionary (1984, recorded in 260,000 items) Even if rewritten to z, 27 words were established.

They are written in alphabetical order: sap, seal, sech, see, seg, sen, Sen. , Sen, sen. , Sing, Sion, sip, site, Sn, s. n. , Sn. Sola, sone, Soo, sool, S. P. G. , Sr, sr, sr. Sr. , SR, Sulu, sulu.

However, some of these words have the same spelling and are due to differences in capital and lowercase letters or the presence or absence of periods.

For example, Zen corresponds to the four words of sen, Sen, sen, and sen in the spelling, but actually only one word of Sen corresponds completely, and similarly Zn corresponds to the Sn, s. n. , Sn, but in reality only one word of Sn corresponds completely, and Zr is Sr, sr, sr. Sr. , SR corresponds to 5 words, but in reality, only 1 word of Sr corresponds completely, and Zulu corresponds to 2 words of Sulu and sulu on spelling, but actually corresponds completely Only one word of Sulu, ZPG and S. P. G is identified by the presence or absence of a period.

Furthermore, four sets of words of Zech and Sech, ZEG and seg, Zola and sola, and zoo and Soo are also identified by distinguishing between uppercase and lowercase letters, and Zion and Sion are identical in substance.

Therefore, there are 12 unidentifiable words, and among these words, three words, see, sing, and sit are ordinary terms, their corresponding zing, zit, and zee are rare terms, and zone is The terminology is a common term and the corresponding one is a rare term, and according to the importance of the pre-registered word, the regular term is first presented as an input candidate, and in most cases there will be no problem .

In this way, there are 12 words that cannot be identified in reality, and among those words, the words with high usage are only three examples: zeal (zeal), seal (seal, storm), and zone (zone). Of these, the usage is greatly different between zone (zone) and sound (unit of loudness of sensation), so only the case of zeal (zeal) and seal (seal, storm) is actually a problem. However, the situation of the appearance of the three words is also very different in this case, so this is also applied to the case of the English sentence, which is already generalized in the Japanese sentence that treats the word as an input candidate with a difference depending on the situation. This can be almost solved.

The next problem is when s and z are in the word or at the end.

Of these, s is frequently used in the change of verbs and nouns in the case of endings, but conversely, if z appears in the ending, it is a proper noun, which is also a foreign language for English. It only appears at the end of the word and can be ignored.

Next, when the z letter appears in a word, there are a very small number of common spellings such as azize, citizen, doze, dozen, horizon, gazeteer, magazine, etc., as well as authorize, characterize, critize, critize, industrialize, memoryize, monopolize, organize, proselyze, rearize, synthesize, revitalize, urbanize, and the case where this size is a noun such as anamorphize.

In the former case, the number is extremely small, and it can be easily confirmed that there is no word in which z in these words is replaced with s other than dose (drowsiness) and dose (dose of medicine).

For the latter case, there are very few examples of words that contain the word ise corresponding to this size, such as exerise, surprise, precise, promise, raise, supervise, treatment, etc., but the size part of these words It can also be easily confirmed that there is no word that is formed by exchanging the “is” part.

By the above, the word registration function displays on the screen a word that is frequently used at the time of input as a first candidate to be selected, and by setting this word to be selected unless a selection act is performed, A keyboard in which s and z belong to one hard key can realize the same function in most cases as a keyboard in which one hard key is assigned to each of s and z.
“Between x and z”

As a result of contrasting all words beginning with x in Kodansha Packs English-Japanese Dictionary (1992, 68000 items included) with all words starting with z in Large Dictionary Research Leaders English-Japanese Dictionary (1984, 260,000 items included), this x Words that are established even when rewritten to z are X-axis and Z-axis, xeno and Zeno, Xing and zing, Zn and Xn, XS and Z. S. The five words.

Among them, Zeno corresponding to xeno starts with a capital letter, zing corresponding to Xing starts with a lower case letter, and Z. corresponding to XS. S. There is a period, and confusion actually occurs in only two examples: Z-axis corresponding to X-axis and Zn (zinc) corresponding to Xn (Christian).

That is, in the case of Z-axis corresponding to X-axis, it is necessary to select from two input candidates, but in the case of Zn (zinc) corresponding to Xn (Christian), word registration is performed. It can be easily identified by the function of scene selection in the case of allocation.

The next problem is whether or not a complementary relationship is established between x and z in the word.

Considering the case where x actually appears in the word, the majority of cases are cases where e and x such as excact, examerate, exalt, examine, example, etc. are combined and come to the beginning as described above. Is actually close to the beginning of the word.

In these examples above, there is no word that is established even if x is changed to z, that is, no word is established by changing ex to ez.

The next problem is whether or not a complementary relationship is established between x and z at the end of the word.

Examples of x appearing at the end of a word are tax, six, sex, mix, fix, etc., but as seen earlier, z does not often appear at the end of the word itself. However, there is no word that holds even if x is changed to z, except that the third person singular form of say is abbreviated as “sez”.

By the above, the word registration function displays on the screen a word that is frequently used at the time of input as a first candidate to be selected, and by setting this word to be selected unless a selection act is performed, A keyboard in which x and z belong to one hard key can achieve the same function in most cases as a keyboard in which one hard key is assigned to each of x and z.
"Complementarity in notation of consonants, semi-vowels and vowels"

As mentioned above, although the complementarity in the spelling between consonants is considered as a problem, the same complementary relationship is also established between consonants, semi-vowels, and vowels.

Such relations typically appear between consonant v, semi-vowel w, and vowel u, and between consonant h, semi-vowel y, and vowel i.
"For consonant v and semi-vowel w"

As a result of contrasting all words beginning with v in Kodansha Packs English-Japanese Dictionary (1992, 68000 items included) with all words starting with w in Large Dictionary Researchers Leaders English-Japanese Dictionary (1984, 260,000 items included), this v Even if rewritten to w, the words that were established were 41 words described in the next section.

Va, VA, Vac, vain, vale, van, vane, vantage, var, vary, vas, base, vast, bat, VAT, vb, veal, beep, veil, verd, Ven, vend, vent, vert, vert, vest, Vet, vex, VF, vile, vin, vine, vino, vis, vise, viz, volley, vow, VP, VS, vv.

Of the 36 words, one word (Ven) starts with v and five words start with w (Wac. WAC → vac, Wan → van, Weil → veil, Wex → vex, WV, WW, WW → vv), and in addition to that, there are a total of 6 things that need to be entered as single characters (Va, VA, VF, VP, VS).

In addition, as can be seen from the above list, most of these words excluding the examples starting with capital letters are vocabularies that are not frequently used on a daily basis.

Furthermore, among these words, words that are used on a daily basis, for example, words starting with w corresponding to words starting with v such as vain, vary, base, vast, vol1y, etc. are respectively wine, ward, waste, waste, words that are unusual vocabularies such as “wolly”, and conversely words that start with “v” corresponding to words used daily such as “went”, “west”, “wet”, “wine”, “wine”, “wise”, etc. It is an extraordinary vocabulary such as vet, vin, vine, and vise, or a vocabulary that is clearly relatively infrequently used.

Therefore, when v and w come at the beginning of a word, the word registration function displays on the screen a word that is frequently used at the time of input as a candidate to be selected, and this word is selected unless a selection act is performed. By setting so that v and w belong to one hard key, it is possible to realize the same function in most cases as a keyboard with one hard key for v and w respectively. Become.

The next problem is whether or not a complementary relationship is established between v and w in the word or at the end of the word.

In general, when v comes at the end of an English sentence, there is no principle, so there is no confusion at this point.

When the case where v actually appears in a word is considered, most of it appears in a typical form or a similar form.

A typical example is that the ending ends with ive and becomes an adjective and ends with ivity and becomes a noun, such as active, activity, passive, and passivity.

Compared to the word including w in this word form, there is no word having a spelling of iwe instead of ive and iwity instead of ivity.

Similarly, there is also no word including the spelling of ewi corresponding to the word including spelling of evi, such as evidence, previous, and review in which i and e are exchanged.

Similarly, when a case where the same vowel is before and after w with respect to a spelling having vowels before and after v is considered, the spelling of ove for ove in the case of “love” and “dove” is other than “owe”. Appearing in the case of, flower, power, however, shower, etc., appearing with a change in the word form such as followed, follower, bestowed, etc., or even for the eve in the case of even, eleven, ever, etc. There are examples such as appearing as the form changes.

In addition, the ave for ave in the case of “have” and “save” is not found except for “awe” itself, and appears as the word form changes as in the case of “awai” for drawing of avi.

Unlike the case of having vowels before and after v as described above, the spelling of wer for words that have the spelling of ver as in the case of universality, over, cover, never, conversion, etc. Appears in the case of power, answer, lower, etc.

In the above example, the common spelling of partial spelling was seen, but the common spelling of these partial spells did not lead to the creation of a common word.

Examples of common spellings that have led to the creation of a common word include words that are low, lower, love, and love in the case of the correspondence between ver and wer. Is an example of having the same spelling due to a change in word form.

Aside from these regular spelling comparisons, there are examples of west and west (chest) as words that can be established even if v and w are directly exchanged. There are examples of move and wave (weave past), vent (hole), and wen (go past).

Thus, when v and w are respectively in the word, it is usual that a common word is generated by the change of word form, and the number is not so many.

Therefore, by using the word registration function, words that are frequently used at the time of input are displayed on the screen as candidates to be selected, and v and w are set by selecting this word unless a selection action is performed. In most cases, it is possible to achieve the same function as a keyboard in which one hard key is assigned to v and w.
“Between semi-vowel w and vowel u”

As described above, it has been described that v and w have a complementary relationship in English spelling, but a substantially similar complementary relationship is established for the semi-vowel w and the vowel u and the consonant v and the vowel u.

First, even in the case of the semi-vowel w and the vowel u, in principle, there is no word formed by replacing w and u in the spelling of one word.

This is because when w and u have the same tone value and are treated as consonants, that is, when w comes to the end and comes to the beginning and then vowels or h (what, who, where, who, when , When, where, while, white, etc.) and r (wrestle, wrap, write, write, long, etc.) and when a specific consonant is requested and it comes in the word and has a vowel behind it, it is written as w This is because u is written when it is treated as a vowel, that is, when it comes to the beginning of a word or at the beginning of a word and then requests a consonant.

Quite exceptionally, there are other words before and after other words, such as a small number with n or d after down, dawn, powder, etc., or a hyphen in here, such as grow-th. There is a vowel-like w in the case of a synthetic word that is located inside and has a consonant behind it, but even in such a vocabulary, the word in which w is replaced with u is not exist.
“Between consonant v and vowel u”

Next, even in the case of the consonant v and the vowel u, in principle, there is no word formed by replacing v and u in the spelling of one word.

Like w and u, the note values of v and u are essentially the same, and when they are treated as consonants, that is, when v comes to the end in the form of ve, This is because “v” is used when a vowel is requested thereafter, and “u” is written when a consonant is requested after the beginning or in the word.

In this case, exceptionally, u is followed after such cases as suit, resume, etc., true, continue, issue, etc., request, equivocal, etc., gradual, etc., continuous, etc. There are cases where vowel notation is required, but even in such a vocabulary, there is no word in which u is replaced with v.
“Between consonant h and semi-vowel y”

As a result of comparing all the words that start with y in the Kodansha Packs English-Japanese Dictionary (recorded in 1992, 68000 items) with all the words that start in h in the Large Dictionary Research Leaders English-Japanese Dictionary (1984, recorded 260,000 items), this y The words that can be established even if rewritten to h are 38 words, which are described in the next section, including 7 ordinary words and 31 ordinary words.

YA, YAG, yb, YB, Yid, Yo, Yob, yr, yah, Yale, yam, yammer, Yank, yap, yarn, yarn, yaw, ye, ear, yarn, yarns, yell, yelp, yen, yep, yester, yet, yew, yip, yipe, yipple, yoics, yoke, your, youw, yoyo, yummy, yup.

Among these 7 abbreviations spelled out, 3 abbreviations starting with y can be distinguished from abbreviations beginning with h.

On the other hand, among these 31 words, 3 abbreviations starting with h can be distinguished from 3 abbreviations starting with h. It is possible to distinguish from abbreviations starting with y.

Many of these 31 words are rare words, and among the abbreviations starting with y, both year and hair and both year and hour are everyday vocabularies, but they have different parts of speech. Among the words that begin with, words that start with hlp and yelp, and hip and yip are everyday vocabularies, and the frequency of occurrence is far superior to the latter. In many cases, it is possible to select an appropriate word.

Next, in the case of the ending of a word, since there are only a few examples such as ah, yah, yeah, oh, etc. where h comes to the end as mentioned above, there is almost no chance of confusion.

In the case of a word, there are very few examples of y appearing in the word, and even in the case of royal, partial, mystical, etc., there are few words that can be established by replacing y with h.

Exceptionally, ordinal numbers such as “forth” and “fifth” are established by changing the radix y of “forty” and “fifty” to h.

Similarly, there are a few exceptions, such as path and patty.

Therefore, by using the word registration function, words that are frequently used at the time of input are displayed on the screen as candidates to be selected, and by setting this word to be selected unless a selection act is performed, y and h In most cases, it is possible to realize the same function as a keyboard in which one hard key is assigned to each of y and h.
"Between semi-vowel y and vowel i"

Similar to the relationship between the half vowel w and the vowel u, in principle, there is no word that is formed by replacing the half vowel y and the vowel i in the spelling of one word.

This is written as y when the note values of y and i are essentially the same and it is treated as a consonant, i.e. when y comes to the end and when it comes to the beginning and then requests a vowel, This is because i is written when it is treated as a vowel, i.e., when i comes into the word and when it comes to the beginning of the word and then requests a consonant.

Very exceptionally, there are vowel-like y in words such as type, metaphysical, dynamic, royal, anonymous, system, analysis and vocabulary derived from them, but even in such vocabularies, style and style With the exception of a few exceptions such as (框), there are no words in which y is replaced by i, ie, words such as type, metaphysical, diasty, loial, anonymous, system, analysis.
“Between consonant h and vowel i”

As a result of contrasting all words beginning with h in the Kodansha Packs English-Japanese Dictionary (recorded in 1992, 68000 items) with all words starting with i in the Large Dictionary Researchers Leaders English-Japanese Dictionary (1984, recorded 260,000 items) The word spelling that was established even if rewritten to i was the six words described in the next section.

Ib, IC, id, Id, ID, ie, it, IU.

Among these words, only the word “it” beginning with “i” and the word “he” beginning with “h” are normal words. In the case of “it”, the corresponding word is “ht. Ht. H. t. And abbreviation. And so on.

Therefore, it is only the word he that starts with h that makes it difficult to input when these two letters belong to one key, but the frequency of he is overwhelmingly high.

In the case of the beginning of the word, words starting with h and words starting with i are displayed on the screen as candidates that should be frequently used at the time of input by the word registration function. By setting this word to be selected, if h and i come to the beginning, give one hard key to each of h and i with the keyboard that has h and i belonging to one hard key. In most cases, the same function can be achieved.

Speaking of word endings, when h comes to the end, there are few cases such as oh, yah, etc., and i comes to the end unless it comes from various words that are foreign words for English, Almost nothing.

The next problem is whether or not a complementary relationship is established between h and i in the word.

Actually, when h in the word may be replaced with i, it is rarely seen except for replacing the the with tie.

This is because h is weakly consonant, and whenever it appears alone in a word, it always requires a vowel before and after it, and when h is sandwiched between i and vowels, at least 3 vowels are consecutive. If h is exceptionally associated with a consonant, it will appear in a typical form such as ch, gh, ph, sh, th, wh.

Actually, in the case of a word including ch, the word in the case of a word including chache, achieve, scalar, gh in the case of a word including ch, in the case of a word including night, light, three, and ph In the case of a word including, shape, and th, the word such as this, that, rater, and other does not become a meaningful word when h is replaced with i, and the spelling that appears there is intuitive It is different from English.

The thee and tie are not only overwhelmingly frequent, but both words have different parts of speech, so the word registration and word assignment functions allow you to select frequently used words as you type. It is displayed on the screen as the first candidate to be selected, and by selecting the word so that it is selected unless a selection action is performed, h and i are assigned to one hard key by a keyboard. In most cases, it is possible to realize the same function as a keyboard in which one hard key is assigned to i.

As a result of the above, it is possible to set five sets of letters of ckq, gj, sxz, uvw, and hiy to the same hard key, respectively.
"Problem of character appearance rate in English"

Therefore, a letter that appears frequently in English is assigned to the first key in the two keys, and only when a letter that cannot be entered with this key appears, press the keyboard switch key and press another key. If the input with this keyboard is completed, it is possible to efficiently input by setting to return automatically to the first keyboard immediately.

In the present invention, an English input keyboard assigned an alphabet with a low appearance frequency assigned by pressing down the keyboard input key, an English input keyboard assigned an alphabet with a high appearance frequency assigned first, and an English input keyboard assigned with a low appearance frequency This is called the input back keyboard.

In order to confirm the appearance frequency of alphabet letters in such English sentences, the English constitution of the United States Constitution on the Internet and the introduction of related events are gathered at random as what can be regarded as almost standard English, The frequency of occurrence of the alphabet letters of.

The English text obtained as a result of the assembly has a total of 44384 alphabets (including codes such as commas and periods), but the number of occurrences of each alphabet (including codes such as commas and periods) is a (3400), b (710), c (1523), d (1529), e (5448), f (1044), g (707), h (2216), i (3093), j (164), k (153), l (1882), m (1045), n (3371), o (3319), p (813), q (38), r (2737), s (2913), t (4049), u (1125), v (493), w (530), x (193), y (620), z (36), (667),. (476),? (5)! (4) :: (72);; (59) for a total of 44384.

Based on the above results, in the present invention, a letter having a high appearance rate in English is put on a key belonging to the English input table keyboard which is entered first when inputting English.

In this case, as a reference for the arrangement of the letters, two kinds of arrangements, that is, an arrangement based on the alphabetical order and an arrangement based on the alphabetical order, are proposed without taking the arrangement found on the so-called qwerty board.

This is related to the appearance of the so-called qwerty board as a character array for a mechanical typewriter.

This is because, at this stage, too fast input causes entanglement of the arm of the mechanical typewriter, and therefore, it is a common theory that a character arrangement for making the input speed as slow as possible is adopted.

On the other hand, in the present invention, a Japanese approach called an English input table keyboard English type, which has an alphabet arrangement most familiar to English-speaking people, and an English input table keyboard Japanese type We propose two types of letter arrangement, the keyboard with the arrangement in the order of Japanese syllabary.

First, the keys belonging to the English input table keyboard English type based on alphabetical order are a, e, h (including i and y), n, o, r, s (including x and z), t, u 9 keys (including v and w) 9 keys with 15 letters in total.

In the case of the English input keyboard English type, its front keyboard, that is, the English character arrangement of the English input table keyboard English type, is as shown in FIG. e, hi in the third column, n in the second row, first column, o in the second column, r in the third column, sxz in the third row, first column, t in the second column, uvw in the third column Arrange the keys.

According to the material of the character appearance rate in the English sentence shown above, among the total of 44384 characters and codes, this 9 sets of 15 characters were found in 33493.

Therefore, the rate at which 33493 keys belonging to the English input table keyboard English type are pressed down in 44384 key presses as a whole, in other words, the appearance rate of characters entered by pressing the key only once. Is 75.46%.

In the case of English input, the letters belonging to the English input back keyboard entered by pressing down the keyboard switch key during input using this English input table keyboard are the remaining b, c (including k and q), d, f , G (including j), l, m, and p, totaling 11 characters (including the sign), there is still one more key in this English input back keyboard. In the present invention, a key referred to as a character large / small mark key is used to convert lowercase letters to uppercase letters and uppercase letters to lowercase letters.

Actually, in the present invention, the first character entered after entering English text and the character entered immediately after entering a period during English text input are automatically set to upper case, In case such an automatic setting does not work, this letter large / small mark key is used to convert the entered lower case letter to upper case and upper case letters to lower case.

That is, when you enter a letter and enter a letter in English, immediately after pressing this letter large / small key, if the letter is lowercase, it will be changed to uppercase, and if it is uppercase, it will be changed to lowercase. Convert it.

Also, if this letter brace is pressed down after specifying a character or letter group that has already been entered with the cursor, the whole letter or letter group is capitalized if it is a lower case letter, If it is uppercase, it is converted to lowercase.

In this way, the back keyboard in the case of the English input keyboard English type, that is, the alphabet arrangement of the English input back keyboard English type, as shown in FIG. Column ckq, third column d, second row first column f, second column gj, third column l, third row first column letter m, second column m, Place the p key in the column.

Hereinafter, the problem of the front keyboard and the back keyboard in the case of the English input keyboard corresponding to the Japanese sentence will be returned to the English input.

In the case of the English input keyboard Japanese-compatible type, the front keyboard, that is, the English input table keyboard Japanese-compatible character layout is changed to the English input table keyboard English type based on the alphabetical order in order to consider the alphabetical order. The key to which it belongs, that is, nine sets of 15 letters of a, e, h (including i and y), n, o, r, s (including x and z), t, u (including v and w). Of the 9 keys that are placed, the key with r is turned on the back keyboard, and the key with ckq placed on the back keyboard.

More specifically, as shown in FIG. 4 (a), the correlation with the Japanese syllabary diagram is obtained, and a 12 in the first row, first column, hi in the second column, uvw in the third column, The e key is arranged in the second row and the first column, the o key in the second column, the ckq in the third column, the sx in the third row and the first column, the t key in the second column, and the n key in the third column.

According to the material of the character appearance rate in the English sentence shown above, among the total of 44384 characters and codes, the nine sets of 15 characters were found in total.

Therefore, the rate at which the keys belonging to the English input table keyboard Japanese-compatible type are pressed during 44384 key presses as a whole, in other words, the key press of the English input table keyboard Japanese-compatible key only once. The appearance rate of characters entered in is 73.16%.

That is, in consideration of the order of the Japanese syllabary, as a result of replacing the r key having a relatively high frequency with the ckq key having a relatively low frequency, the rate at which the key can be input by pressing the key only once is 75. It was about 2.3% down from .46% to 73.16%.

As shown in FIG. 4 (b), the back keyboard in the case of the English input keyboard Japanese-compatible type, that is, the alphabet arrangement of the English input back keyboard Japanese-compatible type is as much as possible with respect to the correlation with the Japanese syllabary diagram. , 9 key, 1st row, 1st column, m, 2nd column, l, 3rd column, r, 2nd row, 1st column, gj, 2nd column, d, 3rd column, b, 3rd row A letter mark is arranged in one column, a key p in the second column, and a key f in the third column.

In the above case, the arrangement of m in the first row, first column, l in the second column, and r in the third column is reminiscently associated with “ma”, “ya”, “ra”, and the second row The arrangement of gj in the first column, d in the second column, and b in the third column corresponds to the arrangement of muddy sounds other than “za” such as “ga”, “da”, “ba”, and the third row, second column. The arrangement of “p” in the third column and “f” in the third column arranges the semi-turbid sound “Pa” that is closely related to “ba” after the muddy sound “ba”.

The number of touches required to input the English text of the United States Constitution on the Internet and the related events mentioned above are calculated using the English input keyboard English type and the English input keyboard Japanese type corresponding to the present invention. I will do it.

First, in the case of the English type input keyboard English type, the total number of characters input by the front keyboard, that is, the number of characters input by pressing the key once is 33493 in total.

Next, in the case of the English type keyboard English type, the number of characters entered on the back keyboard, that is, the number of characters entered by depressing the keyboard key again after depressing the keyboard switch key, and pressing the key twice in total. Is 9608 in total.

Furthermore, in the case of the English type input keyboard English type, the number of characters input on the code keyboard, that is, the key change key is pressed down twice, and then the character key is pressed down again to input the key by pressing the key three times in total. The total number of codes is 1283.

Therefore, in the case of the English input keyboard English type, the number of touches necessary to input the English constitution of the United States Constitution on the Internet and the introduction of events related thereto are 33493 × 1 = 33493, 9608 × 2 = It is calculated to be 56558 degrees, which is the sum of three numbers of 19216, 1283 × 3 = 3849.

This is because a general personal computer inputs this sentence, which is calculated as 44384 by summing up the English letter mother and the sign, as it is by pressing the key of 44384 degrees as it is, but the English input keyboard English of the present invention In the case of the type, the calculation of 56558 ÷ 44384 = 1.743 shows that it is possible to input with a touch of just over 127%, an increase of about 27%.

Further, in the case of the English input keyboard Japanese sentence type in the present invention, the same calculation is performed.

In the English input table keyboard Japanese type, the ckq 1714 key is added by subtracting the 2737 degree key press of the r key from the 33493 degree key press in the English input table keyboard English type. Therefore, it is necessary to depress the key of 32470 degrees.

On the other hand, in the English input back keyboard Japanese type, subtracting the 1714 degree key depression of the ckq key from the 9608 degree key depression in the English input back keyboard English type, the 2737 degree r key In addition, it is necessary to depress the key by subtracting 10631 degrees.

In the following, the number of touches required to input the English text of the United States Constitution on the Internet and the introduction of events related thereto will be calculated according to the English input keyboard Japanese version of the present invention.

First, in the case of the English input keyboard corresponding to the Japanese sentence, the total number of characters input by the front keyboard, that is, the number of characters input by pressing the key once is 32470 in total.

Next, in the case of the English input keyboard Japanese-compatible type, the number of characters input on the back keyboard, that is, the key input by pressing down the key again after pressing down the keyboard switch key, is input by pressing the key twice in total. The total number is 10631.

Furthermore, in the case of the English input keyboard Japanese-compatible type, the number of characters input on the sign keyboard, that is, the keyboard switch key is pressed down twice, then the letter key is pressed down again, and the key is pressed three times. The total number of input codes is 1283.

Therefore, in the case of the English input keyboard Japanese type, the number of touches required to input the English constitution of the United States Constitution on the Internet and the introduction of events related thereto are 32470 × 1 = 32470, 10631 × 2 = 21262,1283 × 3 = 3,849, a total of 57581 degrees is calculated.

This is because a general personal computer inputs this sentence, which is calculated as 44384 by summing up the English letter mother and the sign, as it is by pressing the key of 44384 degrees as it is, but the English input keyboard English of the present invention In the case of the type, the calculation of 57581 ÷ 44384 = 1.2973 indicates that the input can be performed with a touch of 129%, which is an increase of about 29%.

In the case of the present invention, it is desired to perform the same calculation in the case of a general mobile phone. However, the difficulty in that case is that the code input method is generally troublesome in the case of a general mobile phone. Of course, the code input method differs depending on the model, and when inputting a plurality of characters set to one key in succession, there is cursor movement with the cross key, and uniform calculation is performed. It is blocking.

However, these elements are negative factors of a general mobile phone with respect to the present invention. For the time being, these elements are discarded and comparison is made only in the case of character input.

When inputting English text on a general mobile phone, a method of assigning 26 alphabets to 8 keys of abc, def, ghi, jkl, mno, pqrs, tuv, wxyz is common.

Thus, for example, the a key is input by pressing the key once, the b key is input by pressing the key twice, and the c key is input by pressing the key three times.

Multiply this depressing frequency by the frequency of occurrence of each alphabetic letter in the English at random assembly of previous United States Constitution and related event introductions. The number of occurrences of characters is a (3400 × 1 = 3400), b (710 × 2 = 1420), c (1523 × 3 = 4569), d (1529 × 1 = 1529), e (5448 × 2 = 10896) , F (1044 × 3 = 3132), g (707 × 1 = 707), h (2216 × 2 = 4432), i (3093 × 3 = 9279), j (164 × 1 = 164), k (153 × 2 = 306), l (1882 × 3 = 5646), m (1045 × 1 = 1045), n (3371 × 2 = 6742), o (3319 × 3 = 9957), p (813 × 1 = 8 3), q (38 × 2 = 76), r (2737 × 3 = 8211), s (2913 × 4 = 11652), t (4049 × 1 = 4049), u (1125 × 2 = 2250), v ( 493 x 3 = 1479), w (530 x 1 = 530), x (193 x 2 = 386), y (620 x 3 = 1860), z (36 x 4 = 144) And the number 94576 is obtained.

If this is divided by the number of depressing of the key key (33493 + 9608 = 43101) in the case of a general personal computer, it becomes 2.1943, and when inputting this English sentence on a general mobile phone, at least about 2 It can be seen that it is necessary to depress the double key key.

Dividing this by the number of keystroke depressions in the case of the present invention (56558 for English input keyboard English type, 57581 for English input keyboard Japanese type) results in just over 1.672 and less than 1.643, respectively. It can be seen that when the English text is input on a general mobile phone, the keypad key must be pressed down at least about 60% more than in the case of the present invention.

Since this is a number that excludes the sign input problem and the cursor key movement, the actual gap is even greater.

As described above, the input operability of the 9-key portable input terminal of the present invention is much closer to the input operability of a general personal computer than the input operability of a general numeric keypad (actually 12 keys). I understand that.

From the above results, the advantages of the present invention over the currently commonly used method will be apparent.

In addition, when comparing operations that enter English input types, in the case of the present invention, it is necessary to depress the input type switching key at most three times (Japanese → pictograms → numbers → English). It is necessary to depress the input type switching key about 5 times at the maximum (1 → ku → han → a → a → A, etc.).

One difficulty when English input is set as in the present invention is not the case of words, but c, k and q, g and j, s and x and z, h and i and y as simple codes. , A situation occurs in which any one of the five letters of u, v, and w must be input independently.

In this regard, for example, when the ckq key is pressed, the three letters c, k, and q are displayed on the display screen in a form corresponding to the actual keyboard. You can enter what you need among the keys on the actual keyboard by pressing the shift key and then pressing it down.
"Problems with Katakana Character Input"

In the present invention, the katakana character is an auxiliary presence of various character input, and when the input key is pressed after the shift key is pressed during various character input, the katakana character input is entered, and the katakana character input is completed. By depressing the shift key again, and then depressing the input type key, setting is made so that the original input type is restored.
"Problems between numeric input keys and operation keys"

Although the following is repeated, in the present invention, Japanese and English are input with nine keys, so the character input key of 3 rows and 3 columns and the operation key of 1 row and 3 columns are combined, but numeric input In this case, 10 keys are required. Therefore, when inputting numbers, the shift key is selected from among the three operation keys of keyboard switch, shift, and input switch that are set to the operation key of 1 row and 3 columns. Omit it and set the 0 key instead.

In the case of numeric input, the input act itself includes the act of confirming the input. As in the case of Japanese input or English input, input candidate characters are displayed on the screen during input, and this is displayed as a shift key. This is because it is not necessary to change the input phase by depressing and confirm the input of an appropriate candidate.

However, once entering a scene with a different phase, such as a sign input, away from numeric input, a scene where a shift key is required may appear.

Therefore, when entering a scene with a different phase, such as a sign input, away from numeric input, a virtual keyboard with a different phase, such as a sign input, is assumed, assuming that a scene where a shift key is required may appear. It is set only at the position corresponding to the character input key of 3 rows and 3 columns. Here, as in the case where the operation keys of 1 row and 3 columns are input in other Japanese or English, the keyboard switching, shifting, and input switching 3 Set the operation keys to function as they are.

Industrial effect

As described above, according to the present invention, through the rational arrangement of characters and symbols and the cooperation of the display screen and keyboard, operability and functionality equivalent to those of a personal computer, which is different from conventional mobile terminals, is realized. did.

What is expected from this is that, first of all, access to the mobile terminal is remarkably facilitated, the number of users of the mobile terminal is further increased, and the usage of the mobile terminal is expanded.

Secondly, data retrieval and information exchange, which was conventionally performed through a personal computer and therefore under a certain location or in some cases a certain time constraint, has lifted such limitations and has been closely connected to the user. It gives the possibility to be used in the form of writing instruments such as pens, pencils and notebooks.

Even in today's remarkably expanded phase of international exchange, mobile phones with conventional cumbersome input methods are not able to carry out exchanges in English, and international information and international exchanges must be performed exclusively by personal computers.

However, the present invention is expected to significantly develop international information and international exchange through mobile phones.

And since mobile phones go into everyday exchanges, international exchanges are expected to promote exchanges that go into the emotional aspects of specific human relationships.

As described above, the present invention is expected to exhibit effects that extend to conventional industrial structures and changes in human relationships.

Claims (1)

In Japanese input of a portable input terminal with a 3 x 3 keyboard, all consonants are formally divided into consonants and vowels, and the following method is used to automatically change consonants and vowels. Input method to be used. That is, in the 2 rows and 3 columns of them, a nose note that is input to the keyboard is set by combining it with 5 vowels as a formal vowel and a zero note value consonant placed on the consonant keyboard. In row 3, the consonant with zero note value and the consonant keys of k, s, t, n, h are placed, and for the keys of k, s, t, h, they are normally depressed. In some cases, a method of discriminating between clear sound and muddy sound is set in a single depression, such as when the sound value is input as it is, and when it is pressed down for a long time, the muddy sound is input. Realizes automatic alternation of consonant keys and vowel keys between vowels and these consonants, and the m, y, r keys that are input to the remaining one-row, three-column keys by one press and twice When the key of w and p inputted by pushing down and the key is pushed down If the entered character is just normal, it is small, and if it is small, put the large and small keys with the function to change it to the normal size, and the above formal vowels and their formal consonants As a subordinate method under the principle of automatic consonant and vowel replacement, continuous input between consonant keys is guaranteed as necessary. This is an input method that realizes automatic consonant and vowel substitution by dividing all letters into consonants and vowels in a Japanese input of a portable input terminal having a keyboard with 3 rows and 3 columns.
