Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a key input device for inputting Japanese or English. More specifically, the present invention relates to a key input device that can perform an input operation using a mobile phone, a personal digital assistant (PDA), a PHS, an electronic notebook, a wristwatch, a small word processor (word processor), a personal computer (personal computer), or the like.
[0002]
[Background]
When inputting characters with an information device such as a normal personal computer, a keyboard is usually used. This conventional keyboard has more than 80 keys. For this reason, numbers, letters, symbols, etc. can be set separately for each key, and input with a mixture of numbers, letters, symbols, etc., such as e-mail input and address input when browsing the Internet homepage, is performed. Even in this case, input can be made relatively easily by pressing each key.
[0003]
By the way, in recent years, even in a small information device such as a mobile phone, an e-mail transmission / reception function, an Internet homepage browsing function, and the like have been incorporated.
In a small device such as a cellular phone, as many as 80 keys cannot be arranged like a keyboard. For this reason, for example, in a mobile phone, numerals, kana, and alphabets are set to about 12 keys provided for inputting a telephone number.
[0004]
In other words, on a mobile phone, on the surface (key top) of each key is a number, kana ("A, kana, sana, nana, hana, ra, w ...") The alphabet (ABCD ...) is written.
[0005]
However, in such a conventional character arrangement, it is necessary to press a key up to five times to input kana characters and up to four times to input English, which complicates the input operation and makes it difficult to input characters. There was a problem that speedup could not be realized.
In particular, the number of times the key is pressed is set regardless of the frequency with which the character is frequently used. Therefore, when inputting a plurality of characters with kana input, it is necessary to press the key approximately 3 to 4 times on average, and the operation is complicated. there were.
[0006]
On the other hand, as described in Japanese Patent Laid-Open No. 11-134096, for example, five keys out of twelve keys have vowels “A”, “I”, “U”, “E”. , “O” is individually set, and consonants are set for the other seven keys, respectively, so that a key input device that greatly improves input operability is known.
[0007]
In this key input device, vowels that are frequently used in Japanese and English are set to five independent keys, so that the operability at the time of vowel input can be improved and high-speed input can be realized as a whole.
[0008]
[Problems to be solved by the invention]
By the way, consonants “K, S, T, N, H, M, Y, R, W” for inputting clear sounds in the “ka” line to the “wa” line are combined with the vowel key in the Roman character input. There are pieces. For this reason, if there are only seven consonant keys, two of them must be set to the same key as the other consonants. For this reason, in order to input the two keys, an input operation different from that of other consonant keys must be performed. In particular, when inputting Japanese Romaji characters, the input operability of some clear sounds is reduced. There's a problem. For example, when a plurality of consonants are set for the same key, if the first consonant is set to be input once by keystroke and the second consonant is set to be input by keystroke twice, seven consonant keys are set. The seven clear sounds set as the first consonant can be input with a single keystroke, but the other two clear sounds must be input with a double keystroke because they are set as the second consonant. There is a problem that decreases.
[0009]
In addition, the muddy sound input using “G, Z, D, B” in Roman characters is set to the same key as the consonant key for clear sound and is set as the second consonant, so that the input operability is similarly reduced. There is the same problem of doing.
[0010]
Moreover, in Japanese, as shown below, there are many idioms of reading aloud with long roaring sounds “you” and “yuu”.
For example, youth (you Syou), culture (kyou you), consent (Ryou Syou), Myosei (Myou Zyou), excellence (yuu Syuu), tour (Syuu yuu), concentration (Syuu Tyuu), milk (Gyuu Nyuu), Request (you Kyuu), sharing (kyou yuu), supply (kyou Kyuu), hunting gun (Ryou Zyuu), championship (yuu Syou), rest (Kyuu you), religion (Syuu Kyou), employment (Syuu Gyou), etc. .
[0011]
In order to input such long roaring sounds “you” and “yuu” in Roman letters, three keystroke operations are required for the keystroke type, and three touch operations for the key touch type ( In any case, three input operations are required to input three characters. Such long roaring sounds have a high frequency in Japanese, so it has been desired that they can be input with simpler operations even when inputting Roman characters.
[0012]
An object of the present invention is to provide a key input device that can improve the input operability of Japanese Romaji input in a key input device with a small number of keys.
[0017]
[Means for Solving the Problems]
  Of the present inventionThe key input deviceWith reference to the drawings,At least twelve main keys 21 to 32 are provided, and five of the twelve main keys 21 to 25 include vowels “A”, “I”, “U”, “E”, “O” ”Is set individually, consonants are respectively set to the other seven keys 26 to 32, and the five consonant keys 27 to 32 of the seven consonant keys to which the consonants are set are other than the consonant. The second vowels “A”, “I”, “U”, “E”, and “O” are used as consonant vowel combined keys, and four of the five consonant vowel combined keys 27 , 28, 29, and 31 are set to the second consonant “G”, “Z”, “D”, and “B”, respectively, and the other consonant key 32 to which no second vowel is set is substituted. The four consonant vowel combined keys, in which the keys are set and the “G”, “Z”, “D”, and “B” are set as the second consonant, If a consonant vowel combination key other than the input key is input immediately after input, the second consonant set for the first input consonant vowel combination key and the next input consonant vowel combination key are set. Are input in the order of “second consonant + second vowel”, and the four “G”, “Z”, “D”, and “B” are set as the second consonant. When the proxy key is input immediately after the consonant vowel combination key is input, the second consonant set in the input consonant vowel combination key and the second vowel set in the key are “second”. It is set to be input in the order of “consonant + second vowel”.
[0018]
If comprised in this way, if the 2nd consonant set for muddy sounds will strike the consonant key once and will input the consonant key to which the 2nd vowel was set continuously, the 2nd consonant and 2nd Since vowels can be input, it can be input in the same manner as other consonants for clear sounds, and the input operability of Japanese Romaji input can be improved.
In addition, since the proxy key is provided, when inputting the second consonant and the second vowel set as the consonant vowel combination key, it is only necessary to input the consonant vowel combination key and the proxy key continuously. This is the same as other consonant keys, and the input operability can be improved.
[0019]
The key input device includes at least twelve main keys 21 to 32, and five of the twelve main keys 21 to 25 include vowels “A”, “I”, and “U”. , “E” and “O” are individually set, and consonants are set in the other seven keys 26 to 32, respectively, and one of the seven consonant keys in which consonants are set is assigned to one key 26. The consonant “Y” is set, and the other two consonant keys 28 and 29 are respectively set with “ou” and “uu” which are input when input immediately after the input of the consonant “Y” key. It is characterized by being.
[0020]
In Japanese, there are a lot of idioms of reading aloud with long roaring sounds “you” and “yuu”, but to enter these three characters, three keystroke operations are required. Such long roaring sounds have a high frequency in Japanese, so it has been desired that they can be input with simpler operations.
On the other hand, when the predetermined consonant key is input immediately after the consonant “Y” is input as in the present invention, if “ou” or “uu” is set to be output, “you”, The input of “yuu” can be input by two keystroke operations, and the number of keystroke operations can be reduced by one. Therefore, the input operability of Japanese Romaji input can be improved.
[0021]
Here, one of the consonant keys is a consonant key 26 in which two consonants, “Y” as the first consonant and “W” as the second consonant, are set. The other five consonant keys 27 to 31 are consonant vowel combined keys in which the second vowels “A”, “I”, “U”, “E”, and “O” are individually set in addition to the consonants. And a consonant vowel combined key set with the second vowel “A” or “O” immediately after the consonant dedicated key 26 set with “Y” (semi vowel) and “W” (semi vowel) is input. 27, 31 is input, “W + A” or “W + O” is input, and immediately after the consonant key 26 with “Y” and “W” is input, the second vowel “I”, When the consonant vowel combination keys 28 and 29 in which either “U” or “E” is set are input, “Y It is preferred that ou "or" Y + uu "is input.
[0022]
The consonant (semi-vowel) “W” is often used in “W [W] [A]” or “O [W] [O]”, and it is often used as “[W] [I]” or “[W] [ U] ”romaji input is rarely used. Accordingly, the second vowel “I, U, E” is set, for example, “ou” is set to the key 28 where the second vowel “i” is set, and “uu” is set to the key 29 where “u” is set. If “ou” or “uu” is set to the consonant vowel combination key that is set to, the input of “wa,” and the input of the long sound of the stuttering sound can be arranged side by side, further improving the input operability it can.
[0023]
The key input device includes at least twelve main keys 21 to 32, and five of the twelve main keys 21 to 25 include vowels “A”, “I”, and “U”. , “E” and “O” are individually set, and consonants are set in the other seven keys 26 to 32, respectively, and one of the seven consonant keys in which consonants are set is assigned to one key 26. Is set to the consonant “Y”, and the other two consonant keys 28 and 29 are respectively set to “ou” and “uu” for inputting the first consonant sound, and the other two consonant keys 31, 32 is set with “ou” and “uu” for inputting the second consonant sound, and the consonant key 26 with the predetermined consonant keys 27 to 32 and “Y” and the first consonant sound input. If you continuously input the consonant keys 28 and 29 with “ou” and “uu” set, Are output in the order of “first consonant + Y + ou or uu”, and the predetermined consonant keys 27-32 and “Y” are output in the order of “first consonant + Y + ou or uu”. When the consonant key 26 set to “Y” and the consonant keys 31 and 32 set to “ou” and “uu” for inputting the second consonant sound are input successively, the second of the predetermined consonant keys 27 to 32 is input. The consonant, “Y”, and the roar “ou” or “uu” may be output in the order of “second consonant + Y + ou or uu”.
[0024]
At this time, the first consonant of the predetermined consonant keys 27 to 32 is “K, S, T, N, H, R”, and the second consonant is “G, Z, D, B, M”. It is preferable that it is either.
[0025]
According to the present invention, for example, a sound such as “Kyo” and “Gyo” can be input by three key inputs, and the input operability of Japanese Romaji input can be remarkably improved.
[0026]
The key input device of the present invention includes at least twelve main keys, and five of the twelve main keys include vowels “A”, “I”, “U”, “E”. ”And“ O ”are individually set, consonants are set for the other seven keys, and the five consonant keys of the seven consonant keys for which consonants are set are not only consonants. Two vowels “A”, “I”, “U”, “E”, “O” are individually set consonant vowel keys, and four of these five consonant vowel keys are: The second consonant “G”, “Z”, “D”, and “B” are set, and one of the two consonant keys for which the second vowel is not set is “Y” and “W”. It is set as the first consonant and the second consonant, and “M” is set as the second consonant and the proxy key is set in the other key. In both cases, the four consonant vowel combined keys in which “G”, “Z”, “D”, and “B” are set as second consonants or the consonant keys in which “M” is set as the second consonant are used. If a consonant vowel combination key other than the input key is input immediately after the input, the second consonant set for the first input key and the second input consonant vowel combination key are set. Two vowels are input in the order of “second consonant + second vowel”, and the four consonant vowels are set as the second consonant where “G”, “Z”, “D”, and “B” are set as the second consonant When the proxy key is input immediately after the key is input, the second consonant set for the input consonant vowel combined key and the second vowel set for the key are “second consonant + second consonant”. 2 consonant keys are entered in the order of “2 vowels” and the “Y” and “W” are set. When a consonant vowel combination key set with the second vowel “A” or “O” is input immediately after the input, “W + A” or “W + O” is input, and the “Y” and “W” are Immediately after the set consonant key is input, when the consonant vowel combined key set with any of the second vowels “I”, “U”, and “E” is input, “Y + ou” or “Y + uu” May be input.
[0027]
According to the present invention, it is possible to realize a shortened input of “ma line” and “wa line”, a shortened input of muddy sound, and a shortened input of long sound of stuttering. Can be remarkably improved.
[0028]
Here, it is preferable that three consonants are arranged in each consonant key, and a 26-character alphabet is arranged in 12 keys.
In such a case, it is preferable that the consonant is selected according to the number of times of keystrokes in which a plurality of consonants are arranged.
[0029]
Of the 26 letters of the alphabet, if 21 letters (consonants) other than 5 vowels are arranged 3 by 7 on the 7 keys 26 to 32, the 26 letters of the alphabet are input with a very small number of 12 keys. Therefore, it is possible to form the key input device 2 that is small in size and excellent in portability. Furthermore, if three characters are arranged on each of the seven keys 26 to 32 to which consonant keys are set, each key is input up to three times when the input of each character is divided by the number of times each key is pressed. If pressed, any character can be input and the operability can be improved, and since each consonant is evenly arranged on each key, the balance of keystroke operations can be improved and the operability can be further improved.
[0030]
The seven keys 26 to 32 to which the consonant is set are character keys “KGF”, “SZJ”, “TDV”, “NCQ”, “HBP”, “RML”, and “YWX”, respectively. It is preferable that they are set in combination.
[0031]
According to this key input device, consonants “K”, “S”, “T”, “N”, “H”, “M”, “Y”, “R”, and “K” are input in combination with the vowel keys in Roman alphabet input. Since “W” can be set to the first or second character key of each key, a clear consonant having the highest input frequency after the vowel can be input by a simple operation, and the operability can be further improved.
Furthermore, the “G” key for inputting the “Ga” line of muddy sound is input to the “K” key for inputting the “K” line, and the “Z” line is input to the “S” key for inputting the “S” line “Z”. ”Key,“ T ”key for inputting“ Ta ”line,“ D ”key for inputting“ da ”line,“ B ”line for inputting“ H ”key for inputting“ C ”line,“ B ” ”Keys are set, so the related clear and muddy sounds can be entered using the same key (by changing the number of times the key is pressed, etc.). For this reason, it becomes easy to remember the input operation of muddy sound, and can be input at high speed.
[0032]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
This embodiment is used as a key input device 2 of a personal computer 1 as shown in FIG. The personal computer 1 is provided with a mouse 3 and a liquid crystal display 4 and a key input device (key input unit) 2 in which a plurality of keys are arranged.
[0033]
The key input device 2 has a total of 22 keys arranged in approximately four rows, six columns on the left and right. The main key area 20 at the center of the key input device 2 has a vertical key as shown in FIG. A total of twelve main keys 21 to 32 in four rows and three rows are arranged.
In addition, ten function keys 51 to 60 are arranged in a function key area 50 provided in a C shape around the main key area 20.
[0034]
Each character and function is set in the main keys 21 to 32 and the function keys 51 to 60.
That is, on the key surface (key top) of each of the main keys 21 to 32, there are character keys such as alphabets that are input when each key 21 to 32 is pressed alone and are used for Roman input or English input. Is set.
[0035]
Here, the arrangement of the character keys in the main keys 21 to 32 is such that a vowel key is set on the upper side, and a lower side thereof is combined with the vowel key in Roman character input, so A consonant key for inputting "line" is arranged.
[0036]
Specifically, “A”, “I”, “U”, “E”, and “O” representing vowels as character arrays are input to each key 21 to 25 when the key is pressed once. Arranged as a first character key. This arrangement takes into account the ease of remembering letters so that they become “A”, “I”, “U”, “E”, “O” as they go from left to right and from the first level to the second level. Is set.
[0037]
On the other hand, each of the keys 27 to 32 has “K”, “S”, “T” representing Japanese consonants as the first character key (first consonant) input when the key is pressed once. ”,“ N ”,“ H ”,“ R ”consonant keys, and the key 26 has a consonant key“ Y ”. These arrays are designed so that the consonants in the “ka”, “sa”, “ta”, “na”, “ha”, “ra”, and “ya” lines are arranged in almost Akasatana order. It is configured.
The keys 32 and 26 are arranged with consonant keys “M” and “W” as second character keys (second consonants) that are input when the key is pressed twice in succession. Yes. In this arrangement, the remaining “ma” and “wa” rows are arranged.
[0038]
The keys 27 to 29, 31 include “G”, “Z”, “D”, “D”, as second character keys (second consonants) input when the key is pressed twice in succession. Each consonant key of “B” is arranged. That is, the consonants “G”, “Z”, “D”, “B” for inputting the muddy sound “ga” line, “za” line, “da” line, and “b” line are the clear sound “ka” line, “sa” ”,“ Ta ”, and“ Ha ”lines are input corresponding to“ K ”,“ S ”,“ T ”,“ H ”, and arranged so that clear sound and muddy sound correspond to each other. .
[0039]
In addition, in the key 31 in which “H” and “B” for inputting the “ha” row and the “b” row are set, the “pa” row is inputted as the third character key (third consonant). “P” is set, and the input of the “Pa” line is easy to remember and can be performed with good operability.
[0040]
Further, the key 30 with “N” for inputting the “NA” line is also used as a key for inputting the sound repellent “N” in Japanese Roman letter input.
[0041]
Furthermore, the vowel keys 21 and 24 to which “A” and “E” are set are a long sound setting vowel key, a prompt sound setting vowel key, and a long sound “−” and a prompt sound “tsu” as the second character key, Has been.
[0042]
The keys 26 to 29 include “X”, “F”, “J”, “V” as third character keys (third consonants) that are input when the key is pressed three times in succession. Are set respectively.
Furthermore, in the key 30, “C” is set as the second character key (second consonant) in the English input mode, and “Q” is set as the third character key (third consonant). Further, “L” is set in the key 32 as a third character key (third consonant).
[0043]
Therefore, for the 26 letters of the alphabet, the vowels “A”, “I”, “U”, “E”, “O” are independent on the five keys 21-25 out of the 12 main keys 21-32. The other 21 characters are set for each of the other keys 26 to 32. Specifically, the key 26 is “YWX”, the key 27 is “KGF”, the key 28 is “SZJ”, the key 29 is “TDV”, the key 30 is “NCQ”, the key 31 is “HBP”, and the key 32 is “RML” is set.
[0044]
The keys 21 to 32 are pressed simultaneously with the function key 60 in which the first selection input function is set on the upper side of the key tops of the main keys 21 to 32 (above the symbols indicating the characters and functions at the time of single input). As characters of the first selection state inputted at the time, numbers “7”, “8”, “9”, “4”, “5”, “6”, “1”, “2”, “3”, “0”, comma “,”, and period “.” Are set.
[0045]
Furthermore, when the key is pressed at the same time as the function key 59 set with the second selection input function on the lower side of the key top of each of the main keys 21 to 32 (below the symbol indicating the character or function at the time of single input). Various characters and functions of the second selection state to be input are set. When two types of symbols are set on the lower side of the key top, such as the main keys 27, 28, 30, 31, the main keys 27, 28, 30, 31 are held down while pressing the function key 59. When the key is pressed once, each symbol on the left side below the key top is input, and when the key is pressed twice, each symbol on the right side is input.
[0046]
Further, when the key is pressed at the same time as the function key 58 set with the third selection input function, the main key 21 to 32 is input at the upper right of the key top (upper right of the character or function indicating the individual input). Various symbols in the third selected state are set.
Note that the two symbols set at the upper right of the key top are such that when the main keys 21 to 32 are pressed once while the function key 58 is pressed, the left symbols at the upper right of the key top are input and the key is pressed twice. Each symbol on the right side is set to be input.
[0047]
On the other hand, the function keys 51 to 60 are set with various functions used when switching input modes or inputting characters.
[0048]
Next, an input processing function in the key input device 2 having the key arrangement as described above will be described with reference to a block diagram shown in FIG.
First, the key input detecting means 101 detects whether or not the keys 21 to 32 and 51 to 60 have been pressed. For example, if a timer interrupt is performed in a certain cycle (for example, 1 to 10 ms), and I / O ports assigned to the keys 21 to 32 and 51 to 60 are checked to check whether there is a key input or not. Good.
[0049]
If it is determined that there is no key input, the timer interrupt is repeated in a certain cycle and the key input is waited. On the other hand, if it is determined that there is a key input, the key input processing means 102 performs input processing.
When an input mode switching operation is performed by pressing the keys 51, 52, and 54, the mode switching means 103 is operated, and the input mode of the key input processing means 102 is appropriately switched and set. In addition, the mode indicator lamps 61 to 63 formed on the surface of the key input device 2 are turned on and off as each mode is switched.
[0050]
The key input processing means 102 performs processing so that predetermined characters, numbers, and the like are output according to the set input mode and the input key.
Then, the output characters and numbers are displayed on the liquid crystal display 4 via the screen control means 104.
[0051]
Specifically, the input of characters, numbers, and symbols in the key input device 2 is performed as follows.
[Kana mode (Hiragana mode / Katakana mode)]
When the main keys 21 to 32 are pressed in the hiragana mode, the hiragana is input by romaji input. That is, if the vowel keys 21 to 25 are pressed once, a vowel is input, and if the consonant keys 26 to 32 and the vowel keys 21 to 25 are pressed, a hiragana is input as a “consonant + vowel” by romaji input.
[0052]
When the main keys 21 to 32 are pressed in the katakana mode, katakana is input by romaji input as in the hiragana mode.
[0053]
When the vowel keys 21 to 25 are pressed in the hiragana mode and the katakana mode, the vowels are input. At this time, when the vowel key (I, U, O) 22, 23, 25 is continuously pressed twice or more, the alphabet (vowel) is continuously input.
On the other hand, when the long sound setting vowel key 21 and the prompt sound setting vowel key 24 are continuously pressed twice or more, a long sound (-) and a prompt sound (tsu) are input. However, “AA” is input when the key 21 is pressed twice after the consonant, and “EE” is input when the key 24 is pressed twice after the consonant.
[0054]
Each consonant key 26 to 32 is set with three consonants of the first character (first consonant) to the third character (third consonant), and each key 26 to 32 is pressed 1 to 3 times. So that you can select and enter. That is, when the key is pressed once, the character on the left side of each key top is input twice, when the key is pressed twice, the character on the right side is input when the key is pressed three times. Further, when the button is pressed four times, the state returns to the state where the button is pressed once (left side character input).
[0055]
Such an input operation when inputting Roman characters in Japanese is represented by the first key as "Kana standard input" shown in FIG. For example, in order to input the small vowel “A”, the user presses the “R” key 32 three times and then presses the key 21 to input “L + A” and become “A”.
Further, the prompt sound (tsu) can be input by pressing the key 24 twice, but can also be input by “LTU”, that is, “RRRTU”, as in normal Roman character input.
In addition, “Fuji, Jaja, Jyu, Jie, Jyo”, which allows a plurality of inputs in normal Romaji input, can also be input irregularly. For example, “F” can be input by “HU” and “FU (“ KKU ”in this embodiment)”. Similarly, “ji” can be input as “ZI (SSI)” and “JI (SSSI)”.
“Ja” can be input by “ZYA (SSYA)” and “JYA (SSSA)”. The same applies to “Ju, Ji, Jyo”.
[0056]
However, in the kana mode, the consonant key 30 to which “N” is set is not input “C, Q” even if it is pressed twice or three times, and “n” is input when the key is pressed once. When the key is pressed twice, “nn” is input and converted into “n”, and when the key is pressed three times, “nnn” is input and converted into “n + n”. If the key 30 is also pressed four times in succession, the state returns to the state where the main key 30 is pressed once.
When the main key 30 is pressed once, “n” is basically input, but when a main key other than the vowel is pressed after the main key 30, “n” is entered. Converted. For example, when a consonant is input after “SHINKAI” and “N”, “N” is converted to “n” even if the key is pressed once.
[0057]
(Abbreviated input for “Ma line” and “Wa line”)
In the normal input method described above, the keys 26 and 32 are pressed twice when inputting the characters “MA” and “WA” using “M” and “W” set as the second consonant. After the key is pressed, the vowel keys 21 to 25 are pressed once, and a total of three key pressing operations are required. For this reason, such as “ka line” to “ha line”, “ya line”, “ra line” using “K, S, T, N, H, Y, R” set as the first consonant. The keystroke operation is increased once compared with the case where two keystroke operations are sufficient.
[0058]
For this reason, in the present embodiment, the auxiliary array is set so that “MA row” and “WA row” can be input by the same two-key operation as other “ka row” and the like.
That is, in the standard key input operation, the key input device 2 applies vowels “A”, “I”, “U”, “E”, “O” to the keys 21 to 25, respectively, as shown in FIG. Keys with consonants “YWX”, “KGF”, “SZJ”, “TDV”, “N” (in Kana mode), “HBP”, and “RML” respectively set to keys 26 to 32 Characters are input corresponding to the array.
[0059]
With respect to this standard arrangement, as shown in FIG. 6 (virtual consonant arrangement) and FIG. 7 (virtual vowel arrangement), consonant keys (consonant dedicated keys) in which the second consonants “M” and “W” are set. Virtual vowels (second vowels) “a”, “i”, “u”, “e”, and “o” are also set in the five keys 27 to 31 other than 26 and 32 as auxiliary arrays.
These virtual vowels (second vowels) are focused on the fact that consonants are rarely input continuously in Japanese Romaji input, and consonant keys 26 and 32 are followed by consonant keys ( Each of the virtual vowels is set to be input when the consonant vowel key (27-31) is input.
[0060]
As a result, when the keys 27 to 31 are input after the key 32 (“R”), “ma line” is input and the key 26 (“Y”) is continued. When the keys 27 and 31 are entered, “wa, o” is entered, and “ma line” and “wa line” can also be entered by two keystroke operations. Each of these input operations is represented by the first consonant of each key as shown in FIG.
[0061]
(Shortened input of muddy sound)
Similarly, in the normal input method described above, “G”, “Z”, “D”, “B” set as the second consonant is used. In the case of inputting each muffled sound, the vowel keys 21 to 25 are pressed once after the keys 27, 28, 29, and 31 are pressed twice, and a total of three key pressing operations are required.
[0062]
For this reason, in the present embodiment, an auxiliary arrangement is also set so that the muddy sound can be input by the same two-time keystroke operation as other “ka line” or the like.
That is, as shown in FIGS. 6 and 7, consonant keys 27, 28, 29, 31 in which consonants “G”, “Z”, “D”, “B” for inputting muddy sounds are set as second consonants, Consecutive 5 consonant keys (consonant vowel combined keys) 27 to 31 in which virtual vowels (second vowels) “a”, “i”, “u”, “e”, “o” are set as auxiliary arrays The consonants “G”, “Z”, “D”, “B” and virtual vowels “a”, “i”, “u”, “e”, “o”. A muddy sound is input continuously.
[0063]
Note that “GA (G + a)”, “Ji (Z + i)”, “Z (D + u)”, and “BO (B + o)” have the same key as the consonant and the virtual vowel, so that Cannot input using virtual vowels. That is, normally, when the same key is pressed twice, it is the selection of the second consonant of that key and cannot be used as the input of the virtual vowel.
Therefore, if the key 32 is used as a virtual vowel proxy key and the key 32 is pressed immediately after the consonant keys 27-29, 31 are pressed, the consonant keys (consonant vowel combined keys) 27-29, 31 are used. The second consonant “G, Z, D, B” and the virtual vowel set in the consonant vowel combined key are set to be input continuously. Each input operation of these muddy sounds is represented by the first consonant of each key as shown in FIG.
[0064]
(Semi-voice sound abbreviated input)
Further, in the present embodiment, the input of semi-voiced sound can be shortened.
That is, as shown in FIG. 9, in the above-described operation for shortening the muddy sound, the muddy sound “B” is input with a single key press of the “H” key 31, but the key 31 is pressed twice and the virtual vowel 27 By entering ~ 30, semi-turbid sound is input.
Note that “Po (P + o)” is input using the proxy key 32 since the consonant and the virtual vowel are set to the same key as “B (B + o)”.
[0065]
Note that when such abbreviated input is set, “TH” is converted to “DO”, so that tee (THI), di (TTHI), and the like cannot be input. For this reason, when shortened input is set, a processing program may be set so that, for example, input can be made in tee (TYI) or di (TTYI).
[0066]
(Abbreviated input of long sound “you” and “yuu”)
As shown in FIG. 10, the key input device 2 is also provided with an auxiliary array for long roaring sounds. That is, “ou” is set in the key 28 and “uu” is set in the key 29.
[0067]
Thus, as shown in FIG. 11, "you" is input if the key 26 and key 28 are continuously input ([Y] [S] is input). If the key 26 and the key 29 are continuously input ([Y] [T] is input), “yuu” is input. Therefore, a long sound of each roar is input by two keystroke operations.
[0068]
As shown in FIG. 12, “you” is normally input as “you”, but “yo” is input when the previous character is a consonant. In the present embodiment, three consonants are arranged in seven consonant keys, so that different consonants using the same consonant key, such as “KYOU” and “GYOU”, are used. It is necessary to input. Here, when inputting “G”, the “K” key 27 may be pressed twice. However, in this embodiment, the same consonant key is used by the key input after the “Y” key 26. Even in such a case, the input operability is improved by distinguishing between the case where the first consonant is input and the case where the second consonant is input.
[0069]
That is, “ou” and “uu” of the keys 28 and 29 (“S” key 28 or “T” key 29) are input to “Yo” and “Yu”, and “に” is added to the first consonant. It is set to be used when combining "U".
In addition, “ou” and “uu” of the keys 31 and 32 (“H” key 31 or “R” key 32) are set so as to be used when combining “U” and “U” with the second consonant. is doing.
These input key operations are shown in FIG. As shown in this figure, for example, when the “K” key 27, the “Y” key 26, and the “S” key 28 are sequentially input (“KYS” is input), the first consonant of the key 27 is selected and “ “KYOU” ”is input, and when the“ K ”key 27,“ Y ”key 26, and“ H ”key 31 are sequentially input (“ KYH ”is input), the second consonant of the key 27 is selected and“ “GYOU” is input.
Other stuttering inputs are as shown in FIG.
[0070]
At this time, in order to prevent contradictory input operations from occurring in each of the abbreviated input of “ma line”, “wa line”, muddy sound and stuttering sound shown in FIGS. The arrangement of is devised. In other words, the consonant “W” is usually used in “W [W] [A]” or “O [W] [O]”, and “[W] [I]” or “[W] [U] ] "Is rarely used. Therefore, “ou” is set in the “S” key 28 in which the virtual vowel (second vowel) “i” is set, and “uu” is set in the “T” key 29 in which “u” is set. , "Wow," input and the input of long roaring sound.
[0071]
Specifically, as shown in FIG. 7, when the keys 27 and 31 are input after the key 26 is input, “W [W] [A]” and “W [W] [O]” are changed. When the keys 28 and 29 are input after the key 26 is input, by outputting “you” and “yuu” as shown in FIG. "I" and "Wayuki" can be entered easily and in a short time with fewer inputs.
If such a shortened input of stuttering is used, an idiom including a stutter as shown in FIG. 13 can be input by a shortened input with a small number of keystrokes.
[0072]
[English mode]
When the main keys 21 to 32 are pressed in the alphabet mode, each alphabet is input. At this time, if the vowel keys 21 to 25 are continuously pressed twice or more, the alphabet is repeatedly input.
On the other hand, when each consonant key 26-32 is pressed once, the character on the left side of each key top is input twice, when the key is pressed twice, the character on the right side is input when pressed three times. When pressed four times, it returns to the pressed state.
[0073]
Uppercase letters and lowercase letters can be input by switching the input mode first, but the operation becomes complicated when uppercase letters and lowercase letters are mixed as in normal English sentences. For this reason, in this embodiment, in the alphabetic mode, by pressing the main keys 21 to 32 while pressing the Shift key 57, it is possible to switch between uppercase letters and lowercase letters.
[0074]
When two characters set to the same key, such as “K” and “F”, are entered consecutively, pressing and releasing the Ctrl key 56 will determine the number of keystrokes once and separate the preceding and following characters. It is done. When the same consonant is input continuously, the previous character is repeatedly input when the Shift key 57 is pressed and released.
[0075]
[Number mode]
When the main keys 21 to 32 are pressed in the number mode, the numbers written on the upper side of the keys 21 to 32 and “,” and “.” Are input. When pressed multiple times, each number is input as many times as pressed.
[0076]
[Input symbol]
Although the mode for symbol input is not set, the main keys 21 to 32 are pressed once or twice while pressing the function key (third selection input function key) 58 in any of the kana mode, the alphabet mode and the number mode. Thus, the symbols on the upper right side of the key tops of the main keys 21 to 32 can be input.
Further, by pressing the main keys 21 to 32 once or twice while pressing the function key (second selection input function key) 59, the symbols below the key tops of the main keys 21 to 32 can be input.
[0077]
[Input function]
Further, when executing the main function set to each function key 51-60, it is only necessary to directly press each key 51-60. For each function set in the first and second selection states of the keys 21 to 60, the function key (first selection input function key) 60 and the function key (second selection input function key) 59 are pressed with, for example, the thumb of the right hand. However, each key 21-60 is pushed and input with another finger | toe. The function is input by pressing the main keys 21 to 32 while simultaneously pressing the keys 59 and 60.
[0078]
[Enter shortcut]
In a normal keyboard, shortcut input for realizing various functions is realized by simultaneously pressing the Alt, Ctrl, Shift key and other keys. Also in the key input device 2 of this embodiment, since each Alt key 55, Ctrl key 56, and Shift key 57 are provided, these keys 55 to 57 and each key 21 to 60 are input 1 to 3 times. Shortcut input can be realized with.
[0079]
(Effect of embodiment)
(1) According to the present embodiment, since the auxiliary array for “MA row” and “WA row” using “M” and “W” set as the second consonant is set, ”And“ Wa line ”can be input by the same two keystroke operations as“ Ka line ”, and the input operability can be improved accordingly.
Similarly, since an auxiliary array for shortening the muddy sound using “G”, “Z”, “D”, and “B” set as the second consonant is also set, the muddy sound input is the same as other clear sounds 2 Input can be performed with a single keystroke operation, and input operability can be improved.
For example, the example sentence “say myself” shown in FIG. 14 is input to a standard array (“M”, “W”, “G”, “Z”, “D”, “B” are keys 26 to 29, 31). , 32 is input twice by keystroke), 17 keystroke operations are required as shown in FIG. 14 (A), whereas auxiliary array shown in FIG. 14 (B). Since the input of “M”, “W”, “G” and the second vowel can be input with two keystrokes in the same manner as the input of other consonant keys and vowels. It is possible to input by keystroke operation. For this reason, the number of keystrokes (touch) can be greatly reduced, and the input operability can be improved.
[0080]
(2) Furthermore, since the auxiliary arrangement for shortening the long sound of the stuttering as shown in FIG. 10 is also set, “you” and “yuu” can be input by two keystroke operations, and the corresponding key input operation is performed. The number of times can be reduced and the input operability can be improved.
Therefore, when inputting the example sentence “End of Showa Decade” or “Japanese-Western eclectic type” shown in FIGS. 15 and 16, “M”, “W” shown in FIG. Compared to the case where a long sound of a stuttering sound is input by three input operations, the number of input operations can be greatly increased if the input is performed using the virtual vowel and the long sound of a stuttering sound shown in (B) of each figure. Input operability can be improved.
Further, in the other example sentences “selfish children”, “excellent environment”, “working situation” and the like shown in FIG. 17, the number of key input operations can be reduced by using the abbreviated input of this embodiment. Input operability can be improved.
[0081]
(3) In addition, the shortened input of “Ma row, Wa line”, the shortened input of muddy sound, and the shortened input of long sound of stuttering are arranged in an array that is consistent with each other so that key input operations do not overlap in each shortened input. Since it is set, three shortened inputs can be realized simultaneously.
In addition, with only 12 keys 21 to 32, it is possible to realize a function equivalent to Roman keyboard input of a full keyboard with 26 letters set as individual keys, and a very compact and practical key input device. can do.
Furthermore, it is possible to input characters with the same number of keystrokes as the Roman character input using the full keyboard, and the input operability can be improved. For example, when the example sentences shown in FIGS. 14 to 16 are input by romaji input using a full keyboard, the number of keystrokes is 12 times, 17 times, and 16 times, respectively, and the number of keystrokes in this embodiment is 12, 16, and 15 times. Thus, the number of keystrokes can be reduced to the same or less than the case of input using the full keyboard. The same applies to the example sentence shown in FIG.
[0082]
(4) Furthermore, since the Romaji input and the English input can be performed using 12 main keys 21 to 32 which are significantly fewer than the conventional keyboard, the key input device 2 can be reduced in size and the main key can be reduced. 21 to 32 are arranged in three rows and four rows in the same manner as numeric keys on a telephone or a numeric keyboard, and each vowel and first consonant, as well as the second vowel and second consonant, have some degree of regularity. Since the layout of each character is simple and clear, it is very easy to remember, the key position is easy to remember, the blind touch can be easily mastered, the input speed can be the same as the conventional full keyboard, It can be operated with one hand and even beginners can easily master it.
[0083]
(5) As shown in FIG. 7, the auxiliary array sets virtual vowels (second vowels) “a”, “i”, “u”, “e”, “o” in the consonant vowel keys 27-31. Therefore, since the position of the original vowel keys 21 to 25 is simply lowered by two steps, it can be easily remembered, and the position of each virtual vowel can be determined even if it is not written on the key top. It can be easily grasped and entered easily.
[0084]
(6) Furthermore, the standard array in FIG. 5 and the auxiliary arrays shown in FIGS. 6, 7, and 10 are set in positions that are easy to remember and consistent with each other. Easy to set. That is, by setting the position of the virtual vowel (second vowel) to the consonant keys 27 to 31 other than the consonant keys 26 and 32 in which “M” and “W” are set, the second touch operation or two-time keystroke is performed. “M” and “W” that must be input can be input by a first touch operation or a single keystroke, and “Y” and “W” are set to the same key 26 and “ Since “ou” and “uu” that constitute a long sound of a stuttering sound are set together with “Y” in the keys 28 and 29 other than the keys 27 and 31 used for inputting “wa” and “wa”, "Wa" ", a shortened input of muddy sound and a shortened input of long sound of stuttering can be realized side by side.
[0085]
(7) In addition, since the key 26 for inputting “Y” and the keys 28 and 29 for inputting “ou” and “uu” are arranged adjacent to each other, the position is easy to remember and the input operability can be further improved. .
Furthermore, in addition to the keys 28 and 29 as keys for inputting “ou” and “uu”, keys 31 and 32 are provided, and the input of each of these keys 28, 29, 31, and 32 is distinguished, so that “Y The consonant key input before the “” key 26 can be the first consonant or the second consonant. For this reason, for example, “Kyo” can be input with three keys, but also when using a second consonant such as “Gyo”, it can be input with three keys in the same way. Property can be remarkably improved.
[0086]
(8) Since the most frequently used vowels in both Japanese and English, that is, “A”, “I”, “U”, “E”, “O” are set to the independent keys 21 to 25, these characters are the keys. Just press once to enter. For this reason, it is possible to reduce the number of keystrokes when inputting a frequently used vowel. For this reason, input operability can be improved and high-speed input can be performed. Furthermore, since the vowels “A”, “I”, “U”, “E”, “O” are arranged from the first stage to the second stage and from left to right, The key position of the vowel is easy to remember and the operability can be improved.
[0087]
(9) In addition, since the other 21 letters of the alphabet are arranged 3 by 7 on each of the 7 keys 26 to 32, 26 letters of the alphabet can be entered with a very small number of 12 keys. Thus, it is possible to form the key input device 2 that is small and excellent in portability. In addition, since seven keys with consonant keys are set with three characters each, when each character input is divided by the number of times each key is pressed, each key is pressed a maximum of three times. If pressed, any character can be input and the operability can be improved, and since each consonant is evenly arranged on each key, the balance of keystroke operations can be improved and the operability can be further improved.
[0088]
(10) Since the keys are set separately for the keys 26 to 32 in which the consonants “K” to “W” are set and the main keys 21 to 25 in which the vowels “A” to “O” are set, You can input Japanese by entering the consonant + vowel romaji. For this reason, when inputting Japanese, it is possible to input by pressing the key twice on average. For example, “A” line to “WA” line is set to 10 keys, and each key is set. The input operability can be improved and high-speed input can be performed as compared with the 50-tone arrangement in which each character is input by pressing 1 to 5 times.
[0089]
In addition, this invention is not limited to the said embodiment, Other modifications etc. which can achieve the objective of this invention are included, The deformation | transformation etc. which are shown below are also contained in this invention.
For example, it is not necessary to incorporate the auxiliary array for shortening input of “ma line” or “wa line”, the auxiliary array for shortening input of muddy sound, and the auxiliary array for shortening input of long sound of stuttering. "Or" Waco "may be set only for the auxiliary input sequence for shortening input, or may be set only for the auxiliary input sequence for shortened input of muddy sound, or only for the auxiliary input sequence for long sound of stuttering. In addition, only the short input sub-array for "Ma" is set, only the short input sub-array for "Wa", only the short input sub-array for "ou", and only the short input sub-array for "uu" Which auxiliary array is set may be set as appropriate in the implementation.
In particular, if it is possible to set whether or not to use these abbreviated inputs in the input mode, for example, after becoming familiar with standard input operations, the mode can be switched to use the abbreviated inputs of the present invention. It is also possible to select an optimum input method according to the proficiency level of the user.
[0090]
Moreover, in the arrangement for shortening the long sound of the stuttering, “ou” and “uu” are arranged on the keys 28 and 29 set with the virtual vowels “i” and “u”. However, “ou” and “uu” One of these may be arranged on the key 30 in which the virtual vowel “e” is set. In short, “ou” and “uu” may be set to any of the keys in which virtual vowels “i”, “u”, and “e” are set.
Furthermore, in the embodiment, the “ou” and “uu” keys 28 and 29 for the first consonant and the “ou” and “uu” keys 31 and 32 for the second consonant are set separately. Alternatively, only one of the keys 28 and 29 may be provided, and the second consonant may be input by pressing the consonant key twice.
[0091]
In addition, the auxiliary array for shortening input of “ma line” and “wa line” and the auxiliary array for shortening input of long sound of muddy or stuttering are keys connected to the personal computer 1 as in the above embodiment. In addition to the input device 2, for example, it may be incorporated in the key input device 2 of a mobile phone 200 including a microphone 202, a speaker 203, a liquid crystal display 204, etc. as shown in FIG.
Further, it may be incorporated in a personal digital assistant (PDA) 300 as shown in FIG. In particular, since the present invention can input characters with 12 keys, it can be easily applied to very small devices such as the mobile phone 200, the PDA 300, and a wristwatch.
[0092]
Furthermore, the present invention can also be used in a screen display type key input device that selects and inputs keys displayed on the screen 301 by a touch type input means (such as a pen or a finger) as in the PDA 300 of FIG. In the screen display type key input device, when a plurality of characters are set for one key, the number of touches of the key and the key touch method (for example, point touch that inputs the screen 301 with a point and a certain amount of movement) However, the present invention can be applied to any screen display type key input device.
Even when the present invention is applied to such a screen display type key input device, “M”, “W”, consonant for muddy sound and the like are not input by touching the liquid crystal key part twice or by touching the bar. Like a consonant key, it can input by a single touch or a pin touch, and can greatly reduce the number of keystrokes (touch) and improve input operability.
[0093]
Furthermore, since the screen display type key input device can switch the screen display, when the consonant key 32 is touched, the part of the consonant keys 27 to 31 is switched to the virtual vowel as described in FIG. Subsequently, when the vowel keys 21 to 25 are touched, the input is “Raku”, and when the virtual vowel keys 27 to 31 are touched, the “ma row” is input. It is good also as a screen display easy to do.
[0094]
Similarly, when the consonant key 26 is touched, virtual vowels “a” and “o” are displayed on the consonant keys 27 and 31, and “ou” and “uu” are displayed on the consonant keys 28 and 29, When the vowel keys 21 to 25 are touched after the key 26, “ya row” is input, and when the virtual vowel keys 27 and 31 are touched after the key 26, “wa,” is input. When the keys 28 and 29 are touched after the key 26, “you” and “yuu” may be input to make the screen display easier to operate.
[0095]
Furthermore, for example, the key 27 is pressed or touched when inputting the cloudy sound “G (ga row)”, “Z (za row)”, “D (da row)”, “B (ba row)”. At this time, virtual vowels are displayed on the keys 28 to 32, and when the vowel keys 21 to 25 are pressed or touched after the key 27, “ka line” is input. When the key 32 is pressed or touched, “GA” may be input. When other consonant keys 28, 29, and 31 are pressed or touched, they can be input in the same manner by displaying virtual vowels on consonant keys other than that key.
[0096]
Furthermore, in the screen display type key input device, the screen display can be switched according to the touch operation of each consonant key 27-31, so that the position of the virtual vowel is not fixed, for example, the input consonant You may make it change suitably according to a position. Even in this case, since each virtual vowel can be displayed on the screen, it is possible to perform an input operation of “ga line, zigzag, daboshi, ba line” without significantly reducing operability.
[0097]
Moreover, you may change the keyboard layout of the character keys 21-32 suitably. For example, in the above embodiment, the vowel “A, I, U, E, O” is set to the upper two keys 21 to 25 of the main key area 20, but the middle two keys or the lower two keys. The consonants may be set for the remaining keys. Further, by setting the vowels “A, I, U, E, O” to the keys 21, 24, 27, 30 in the left column of the main key area 20 and the keys in the center column, etc. Alternatively, it may be set to a key in the center column and the right column, or a key in the left and right columns.
In addition, the present invention is not limited to a key input device having 12 main keys in four rows and four columns on the upper and lower sides. For example, another arrangement such as three columns on the upper and lower sides and four rows on the left and right, and 13 or more main keys. The present invention can be widely applied to key input devices provided.
[0098]
The models and applications in which the key input device of the present invention is used are not limited to the personal computer input device 2, the mobile phone 200, and the personal digital assistant (PDA) 300, but also a notebook personal computer, mobile personal computer, PHS, and electronic notebook. Also, it can be used for key input devices of information processing equipment such as calculators and pen-touch keyboards, key input devices built into measurement and control equipment, and home appliances such as Internet TV remote controls. Good.
[0099]
【The invention's effect】
According to the key input device of the present invention, the following effects can be obtained.
According to the key input device of claim 1, even if it is the second consonant set as another consonant key, if the consonant key is pressed once and then the consonant vowel combined key is input, Since the second consonant and the predetermined vowel can be input, the second consonant and the predetermined vowel can be input by the same operation as other consonants for clear sound, and the input operability can be improved.
[0100]
According to the key input device of claim 2, consonants “K”, “S”, “T”, “N”, “H”, “Y”, “ “R” can be set to seven consonant keys, and “W” and “M”, which are slightly less frequent than these, are set as the second consonant of the consonant key. Can be improved.
[0101]
According to the key input device of the third aspect, the second consonant and the second vowel can be input with the second consonant “G, Z, D, B” for the muddy sound, the consonant vowel combined key and the substitute key. Therefore, it is possible to input with the same operation as other consonants for clear sound, and the input operability can be improved.
[0102]
According to the key input device of claim 4, when a predetermined consonant key is input immediately after the consonant “Y” is input, “ou” or “uu” is output, and “you” and “yuu” are input. Since each can be input by two keystroke operations, the input operability can be improved.
[0103]
According to the key input device of the fifth aspect, it is possible to make the input of “wa, wow” and the input of the long sound of roaring parallel, and the input operability can be further improved.
[0104]
According to the key input device of claim 6, it is possible to realize a shortened input of “ma line” and “wa line”, a shortened input of muddy sound, and a shortened input of long sound of stuttering. The input operability can be significantly improved.
[0105]
According to the key input device of the seventh aspect, since the other 21 letters of the alphabet are arranged three by seven on the seven keys 26 to 32, the alphabet with a very small number of keys of 12 26 characters can be input, and the key input device 2 having a small size and excellent portability can be formed. Furthermore, since the seven keys 26 to 32 to which the consonant keys are set are arranged with three characters each, each key is assigned when the input of each character is divided by the number of times each key is pressed. If the key is pressed a maximum of three times, any character can be input and the operability can be improved, and the consonants are evenly arranged on each key, so that the balance of keystroke operations can be improved and the operability can be further improved.
[0106]
According to the key input device of claim 8, consonants “K”, “S”, “T”, “N”, “H”, and “M” that input the “ka” line to the “wa” line are combined with the vowel key in the Roman character input. , Y, R, W "can be set as the first or second character key of each key, so that the consonant of the clear sound that is frequently input next to the vowel can be input with a simple operation, further improving the operability. can do.
Furthermore, the “G” key for inputting the “Ga” line of muddy sound is input to the “K” key for inputting the “K” line, and the “Z” line is input to the “S” key for inputting the “S” line “Z”. ”Key,“ T ”key for inputting“ Ta ”line,“ D ”key for inputting“ da ”line,“ B ”line for inputting“ H ”key for inputting“ C ”line,“ B ” ”Keys are set, so the related clear and muddy sounds can be entered using the same key (by changing the number of times the key is pressed, etc.). For this reason, it becomes easy to remember the input operation of muddy sound, and can be input at high speed.
