Description

The present invention relates to a Japanese input device and method, and more particularly, to a Japanese input device and method using at least 10 keys such as a mobile phone, a PDA (personal information terminal), a digital TV remote controller and the like.

In a conventional Japanese input device such as a mobile phone, the kana characters at the top of each line of the 50 sound chart are assigned to 10 keys and expressed, and each time the same key is pressed, it is displayed on the key each time it is pressed. A method is used in which the kana characters in each row of the line are cyclically displayed and the desired kana characters are input (refer to Patent Document 1; hereinafter referred to as “kana key repeated typing method”). The kana key continuous hitting method has several drawbacks. (1) The input speed is slow because the number of key presses is large. For example, the input of the kana character “po” needs to be pressed seven times (5 times of “ho” +2 times of semi-voiced sound). (2) When inputting, it is necessary to count the number of times of pressing or select while looking at the display screen, and since the number of key pressings of the kana characters in each row on the same line is different, It has become difficult to input smoothly.

In addition, a conventional device such as a mobile phone uses a Japanese input method called “pager input method” and is also disclosed on the Internet (search keyword: “pager input method”). In the pager input method, the kana characters in the first row of each 50 syllabary are assigned to 10 keys and expressed, and by pressing the key twice, one kana character in the syllabary diagram is input and the first time. The key of represents the line to which the kana character written on the key belongs, and the second key represents the specific stage of the bank by the number displayed on the key ("1" is the top, "2" is Thus, the corresponding kana character is input. Compared with the kana key continuous hitting method, the pager input method can input the kana characters of the syllabary by pressing the fixed key twice, but the pager input method also has some drawbacks. (1) It is difficult to memorize the input method. (2) When inputting a muddy / semi-voiced kana character, it is necessary to further press another muddy sound key or a semi-voiced sound key. In such a case, the number of times of pressing is 3 or 4 times (2 To enter a semi-turbid sound by pressing once).
JP-A-7-78045 (first page)

The present invention relates to a Japanese input device or method using at least 10 keys, and the number of key presses in the conventional device or method is large, the input cannot be performed smoothly, and an efficient input method is difficult to learn. In order to solve the problem of complicated input such as semi-sounds, low-tones, stuttering sounds, etc. It is easy to learn the input method with consonants and vowel romaji written by pressing the key twice, and each key key is written. The purpose is to input two kana characters efficiently. In addition, the present invention replaces the Romaji characters in the present invention with the corresponding Adan / Akina kana characters, so that even those who do not know the Romaji can easily learn the input method using the Adan / Ago kana characters written for each main key. The purpose is to become.

The present invention divides the entire consonant romaji of kana into two groups, adds a vowel romaji for each group, and adds two consonant romajis belonging to two groups and one vowel romaji belonging to one group for each main key. Assign all kana characters by pressing the main key twice to enter one kana character in the form of “consonant (belonging to the same set as the vowel) + vowel”. Using the consonant sound and stuttering notation method as a reference, a consonant duplication key is provided, the consonant and subsequent kana are efficiently input in the form of “consonant + consonant duplication + vowel”, and the stuttering key (y) is provided and “consonant + The gist is to efficiently input stuttering in the form of “vowel y + vowel 2”.

In the present invention, the following terms are used. In the present invention, hiragana and katakana are not particularly distinguished. Whether it is hiragana or katakana is determined by the input state of the input software. The conversion from hiragana to foreign word katakana and kanji is a problem that belongs to the area of language processing software as a subsequent process of hiragana input processing, and is not mentioned in the present invention. "Romaji" refers to the Romaji in how to spell Japanese Romaji. The Japanese romaji spelling means an existing Japanese romaji spelling, a modified version thereof, or a completely new Japanese romaji spelling. The method of spelling Japanese Romaji, which uses one letter in multiple Roman letters, is not adopted. The syllable “y” is considered as a consonant in the case of a line and as a vowel in the case of stuttering. Stuttering vowels are divided into two vowels. For example, in the case of kya, vowels y and a are considered separately. Since Ayokomana has no consonants, Ayakana is also expressed in the form of “consonant + vowel”, so the term “Ayashi virtual consonant” is introduced, and “Ayokoname” is “Ayoko virtual consonant + vowel”. It is expressed in the form of The term “special virtual consonant symbol” is introduced to express the sound, repellent and long sound in the form of “consonant + vowel”, and the sound “sound, repellent, long sound and some sentences in the form of“ special virtual consonant symbol + vowel ”. Enter the symbol. In claim 1 and claim 7, the kana consonant Romaji and A-line virtual consonant symbols are called “consonant symbols”. In claim 2 and claim 8, the kana consonant Romaji, the A-line virtual consonant symbol, and the special virtual consonant symbol are referred to as “consonant symbols”.

In the device related to the present invention, at least 10 main keys are provided. The entire consonant symbol twice the maximum number of main keys is divided into two groups, and the two groups are called group A and group B, respectively. Group A and Group B each contain the same number of consonant symbols as the maximum number of main keys. Romaji representing five vowels ("A", "I", "U", "E", and "O" syllables) is added to A set, and these five vowel Romaji are also added to B set. For each main key, two consonant symbols belonging to the A and B groups and one vowel Roman character belonging to the A or B group are assigned and described. Some primary keys may have only one consonant symbol assigned. Group A and Group B are distinguished by uppercase / lowercase letters, different colors, different positions, or combinations thereof for easy identification. Conversion from consonant symbols and vowel romaji to kana characters is performed by a romaji kana character conversion table. The rows of the Romaji-kana character conversion table represent kana consonant symbols, the columns represent the kana vowel Roman characters, and the corresponding kana characters are written at the intersections of the rows and columns. When you press the main key twice, select the consonant symbol that belongs to the same set as the vowel romaji of the second main key among the two consonant symbols of the first main key. And enter the kana characters determined by the romaji kana character conversion table. The voiced / semi-phonetic kana is not in the conventional “50-sound figure kana + saku / semi-voice symbol” format, and is input as a single kana character by pressing the main key twice. When inputting stuttering using only the main keys, enter stuttering kana characters in uppercase and lowercase letters.

One consonant duplication key is provided in order to input prompt sounds, repellent sounds, and long sound symbols more efficiently. Do not assign other consonant roman letters to the main key assigned the consonant roman letter “N”, and press the main key assigned the consonant roman letter “N” and the duplicate consonant key twice in order to change the sound repellent character (n). input. When you press a key, a consonant duplication key, and a key that are not assigned a consonant Roman letter “N” three times in order, the third key among the two consonant symbols of the first key Select a consonant symbol that belongs to the same set as the vowel romaji, and the consonant duplication state is determined by the second consonant duplication key. In the third main key, the vowel romaji is selected and the consonant character corresponding to the consonant duplication state () And the subsequent kana characters determined by the romaji kana character conversion table are input simultaneously. Do not assign a consonant roman character other than the lowercase consonant roman letter “l” to the main key assigned the A line virtual consonant symbol, and press the main key assigned the A line virtual consonant symbol and the duplicate consonant key twice in order. To enter a long clef (-).

In order to more efficiently input stuttering characters whose vowels begin with “y”, one stuttering key is provided. The conversion from the consonant symbol of the stuttering and the last vowel romaji to the stuttering character is performed according to the Romaji stuttering character conversion table. The row of the Romaji stuttering character conversion table represents the consonant symbol of stuttering, the column represents the last vowel Roman character of stuttering, and the corresponding stuttering character is written at the intersection of the row and column. When one key, key key, and key are pressed three times in order, the consonant symbols that belong to the same set as the vowel romaji of the third main key among the two consonants of the first main key The sound input state is determined by the second sound key, and the vowel Roman character is selected by the third main key, and two kana characters of the sound determined by the Roman character conversion table are input simultaneously. When you press a key, a consonant duplication key, a stuttering key, and a main key that are not assigned the consonant Romaji “N” four times in sequence, you will be prompted to enter the two letters of the prompting sound (tsu) and the following stuttering simultaneously. To do.

In order to make the present invention usable even for those who do not understand the Romaji, the A line virtual consonant symbol and the consonant Romaji in the present invention are respectively replaced with the corresponding Adan kana characters, and the vowel Roman characters are respectively replaced with the corresponding A kana characters. It may be replaced.

According to invention of Claim 2 or Claim 8, there exists the following effect. (1) In the present invention, when inputting all kana characters including muddy sounds, semi-voiced sounds, stuttering lowercase letters, prompting sounds, repelling sounds, and long sound symbols, the number of key presses for each character is two times. The number of key presses is less than the maximum of 7 times and an average of 4 times. For example, when “Good morning” is input, the number of key presses is 26 times in the kana key continuous typing method, and 18 times in the present invention. The number of pressings of the present invention is small even compared to 20 times of the pager input method. (2) In the present invention, the number of key presses for each character required for inputting all the kana characters is uniform, and it is not necessary to select the number of presses while counting or looking at the display screen. Compared with the kana key continuous typing method, kana characters can be input continuously and smoothly. In the pager input method, characters such as muddy sounds and semi-turbid sounds need to be pressed, so that the present invention can input kana characters more smoothly than in the pager input method. (3) Since Roman characters are written for each main key of the present invention, it is easier to learn the input method than the pager input method. (4) In the present invention, it is possible to input all kana characters including muddy sound, semi-voiced sound, lower-cased sound, prompting sound, repelling sound and long sound with only 10 keys. Use fewer keys.

According to the fifth or eleventh aspect of the invention, in addition to the effect of the second or eighth aspect of the invention, the following effects can be obtained. (1) In the present invention, “consonant + consonant duplication key + vowel” is described with reference to the notation (tsu) and subsequent kana characters in the form of “consonant + consonant + vowel” in the existing Japanese romaji spelling. ”And the subsequent kana characters can be input in the format of“ ”, so that it is possible to input the prompting and subsequent kana characters more efficiently than in the kana key continuous typing method and the pager input method. It becomes easy to memorize. (2) Since the consonant duplication key of the present invention can be used only from the time when the consonant key is pressed until the time when the vowel key is pressed, it is not necessary to provide the consonant duplication key. Even if an existing key other than the primary key is used, the existing function of the key is not affected.

According to the invention described in claim 6 or claim 12, the following effect is obtained in addition to the effect of the invention described in claim 5 or 11. (1) In the present invention, the number of key presses required to input two characters of a stuttering sound whose vowel begins with “y” is three times, so that the stuttering character is more efficient than the kana key continuous hitting method and the pager input method. Can be entered manually. Since the sound of the roaring sound matches the key to be pressed, there is no inconvenience when inputting the two characters of the roaring sound separately. (2) Since the stuttering key of the present invention can be used only from the time when the consonant key is pressed until the time when the vowel key is pressed, it is not necessary to provide the stuttering key. Even if an existing key other than a key and a consonant duplication key is used, the existing function of the key can be processed so as not to be affected.

According to the invention described in claim 13 or claim 14, even if a person who does not understand Roman characters can use the present invention by using the kana / a kana written for each key.

Hereinafter, the best embodiment of the present invention will be described with reference to FIGS.

Ten existing numeric keys on a device such as a cellular phone may be used as the main key of the present invention. Numbers “1” to “9” and “0” are assigned to the ten main keys, respectively, and these numbers are referred to as “key numbers”. A specific main key can be uniquely determined by a key number. The symbol “_” (underline) represents a row virtual consonant symbol, and the kanji “notation” represents a special virtual consonant symbol. As shown in FIG. 1, the A-line virtual consonant symbol “_”, consonant Roman letters “K”, “S”, “T”, “N”, “H”, “M”, “Y”, “R” and `` W '' and vowel roman letters `` A '', `` I '', `` U '', `` E '' and `` O '' are arranged in A set, consonant roman letters `` g '', `` z '', `` d '', `` b '', “P”, “l”, “f”, “y” and “v”, special virtual consonant symbol “notation” and vowel Roman letters “a”, “i”, “u”, “e” and “o” It is arranged in B group, and for each main key, two consonant symbols belonging to A group and B group and one vowel Roman letter belonging to A group or B group are assigned and described. In FIG. 1, the upper and lower case letters and the A group and the B group are distinguished at different positions, but it is desirable to distinguish them with different colors rather than upper and lower case letters. The grouping of consonant symbols and vowel romajis shown in FIG. 1 and the arrangement of the keys into the keys are: how to spell Japanese romaji, how often kana characters are used, distance between consonant keys and vowel keys corresponding to kana characters, mobile phones, etc. However, the present invention is not limited to this form, and any form within the scope of the present invention may be used.

Conversion from consonant symbols and vowel romaji to kana characters is performed by a romaji kana character conversion table. For the convenience of creating the software related to the present invention, it is preferable to convert the Roman character kana character conversion table into the key number kana character conversion table. In the key number kana character conversion table, the rows and columns respectively represent the first key number and the second key number (when using the consonant duplication key, the first key number and the third key number), The corresponding kana character is written at the intersection of the columns. Speaking of the conversion procedure from the romaji kana character conversion table to the key number kana character conversion table, the two key numbers corresponding to the consonant symbols and vowels corresponding to the kana characters in the romaji kana character conversion table are shown in FIG. The two key numbers are set as the row and column of the key number kana character conversion table, respectively, and the kana character is written at the intersection of the row and column. FIG. 3 is a key number kana character conversion table corresponding to the key arrangement of the consonant symbols and vowel Roman characters in FIG. In the key number kana character conversion table shown in FIG. 3, the kana character of that line is represented by a combination of the “A” virtual consonant symbol “_” (underline) and the A set vowel. When not using the stuttering key, enter the stuttering in uppercase and lowercase letters. A concatenation of the consonant “l” and the B group vowel represents a lowercase letter. A lower case letter is represented by a combination of a consonant written in lowercase “y” and a B group vowel. In the case of concatenation of consonants “f” and “v” and group B vowels, if there is a corresponding stuttering, two characters of stuttering are input simultaneously. The combination of the special virtual consonant symbol “symbol” and the B group vowel represents the repellent sound (n), the punctuation symbol (,), the prompt sound (t), the punctuation symbol (.), And the long sound symbol (-). "A" in the Roman letter "bati" of "Bachi", "o" in the Roman letter "tyou" of "Chou" and "u" in the Roman letter "soku" of "Soku" You may memorize | store the 2nd key of a long sound symbol "-" and a prompt sound ().

The principle of the Japanese input device based on the main key of FIG. 1 and the key number kana character conversion table of FIG. 3 is as follows. When inputting one kana character, the main key on which the consonant symbol of the kana is written is pressed as the first key, and the second key belongs to the same set as the consonant of the kana By depressing the main key on which the vowel is written, the first key number and the second key number are acquired, and the kana character is input by the key number kana character conversion table of FIG. For example, if you want to enter "Good morning", you can press the main keys with symbols in "_OHAYO_Ugoza_IMASU" in that order. When expressed by a key number, “156185136076127133” is obtained. As another example, when “I welcome you” is input, the symbol array and key number array of the pressed key are “_IRA entry uSIya_IMASE” and “1291583236127134”, respectively.

One consonant duplication key is provided in order to efficiently input the prompting sound and the subsequent kana character, sound repelling and long sound symbol. As shown in FIG. 2, an existing telephone key “#” in a device such as a mobile phone may be used as the consonant duplication key of the present invention. The consonant duplication key is written in the Chinese character “heavy”. Since the consonant duplication key in the present invention can be used only from the time when the consonant key is pressed until the time when the vowel key is pressed, this key is used for other functions in Japanese input software. Can be processed so as not to affect its function.

The input principle of the sound repellent, prompting sound and long sound symbol of the Japanese input device based on the main key and consonant duplication key of FIG. 2 and the key number kana character conversion table of FIG. 3 is as follows. As shown in FIG. 2, when consonant symbols and vowels are assigned to the main key, no other consonant Roman letters are assigned to the main key on which the consonant “N” is written. As a result, when the main key in which the consonant Roman letter “N” is written and the consonant duplication key are pressed in order, it is uniquely interpreted as “NN” and further converted into a sound repellent “n”. When simultaneously trying to input a kana character and a subsequent kana character starting with a consonant other than “N”, the main key on which the consonant roman letter of the subsequent kana is written is pressed as the first key. Press the consonant duplication key as the second key. As the third key, the main key on which the vowel romaji belonging to the same set as the consonant romaji of the subsequent kana is pressed is pressed. As a result, the first key number and the third key number are acquired, the prompt input state is determined by the second key, and determined by the prompt character according to the prompt input state and the key number kana character conversion table of FIG. Enter the following kana characters. For example, when trying to input “Motto”, it is possible to press the main key and the consonant duplication key (heavy) in which the symbols in “MOT heavy E_IRU” are written in that order. When expressed by the key number, it becomes “754 # 41293”. A key lower letter consonant Roman letter “l” is assigned to the main key in which the letter “_” (underline) is written. As a result, when the main key in which the A-line virtual consonant symbol “_” and the consonant duplication key are pressed in order, the long symbol “−” is uniquely input.

A roaring key is provided to efficiently input a roaring character whose vowel begins with “y”. As shown in FIG. 2, an existing telephone key “*” in a device such as a mobile phone may be used as the roaring key of the present invention. Indicate the roaring key with the roman letter "y". The stuttering key in the present invention can be used only from the time when the consonant key is pressed until the time when the vowel key is pressed, so even if this key is used for other functions in Japanese input software. , It can be processed so that its function is not affected.

The conversion of the consonant symbol of the stuttering whose vowel begins with “y” and the last vowel Romaji to the stuttering character is performed by the Romaji-stuttering character conversion table. For the convenience of creating the software related to the present invention, it is preferable to convert the Roman character stuttering character conversion table into the key number stuttering character conversion table. In the key number stuttering character conversion table, the row and column represent the first key number and the third key number, respectively, and the corresponding stuttering character is written at the intersection of the row and column. Speaking of the conversion procedure from the Romaji phonetic character conversion table to the key number phonetic character conversion table, the consonant symbol and the last vowel corresponding to the phonetic character in the Romaji phonetic character conversion table, and two keys corresponding to FIG. A number is determined, and the two key numbers are set as rows and columns of the key number stuttering character conversion table, respectively, and the stuttering characters are written at the intersections of the rows and columns. FIG. 4 is a key number stuttering character conversion table corresponding to the consonant symbol / vowel Roman character key arrangement of FIG. In the key number stuttering character conversion table of FIG. 4, there is a place where empty cells are filled with some straight sounds or sentence symbols.

The key input principle of the Japanese input device based on the main key and key key in FIG. 2 and the key number / character conversion table in FIG. 4 is as follows. When two characters of a stuttering sound whose vowel begins with “y” are to be input simultaneously, the main key on which the consonant symbol of the stuttering is pressed is pressed as the first key. Press the stuttering key as the second key. As the third key, the main key on which the last vowel belonging to the same set as the consonant symbol of the stuttering is written is pressed. As a result, the first key number and the third key number are acquired, the stuttering input state is determined by the second key, and the stuttering character is input by the key number stuttering character conversion table of FIG. For example, when trying to input “Ojamamasa”, it is possible to press the main key or the roaring key (y) in which the symbols in “_OzyaMASIMASU” are written in that order. When expressed by the key number, it becomes “157 * 671327133”. As another example, if you want to enter "Islaimase", press the main key with the symbol in "_IRAS heavy yA_IMASE", the consonant duplication key (heavy) and the stuttering key (y) in that order. If you can. When expressed by a key number, it becomes “12913 # * 1127134”. This example is a special case where the kana following the sound is a stuttering sound.

In order to make it possible for a person who does not understand Roman letters to use the present invention, the virtual consonant symbol “_” and the consonant Roman letters “K”, “S”, “T”, “N”, “H” in the above embodiment are used. , “M”, “Y”, “R”, “W”, “g”, “z”, “d”, “b”, “p”, “y” and “l” respectively. Kana characters “a”, “ka”, “sa”, “ta”, “na”, “ha”, “ma”, “ya”, “ra”, “wa”, “ga”, “the”, Replaced by “da”, “ba”, “pa”, “ja”, and “a”, and the vowel Roman letters “A”, “I”, “U”, “E”, and “O” of A group respectively corresponded Replace it with the kana characters “a”, “i”, “u”, “e” and “o”, and the vowel Roman letters “a”, “i”, “u”, “e” and “ "o" may be replaced with the corresponding A-kana characters "a", "b", "c", "e" and "o", respectively. The consonant Roman characters that cannot be replaced may not be used.

The original basic function of mobile phones was voice communication, but now the demand for “silent communication” is increasing, and fusion with PDAs and electronic dictionaries can be expected. It can be applied to solve Japanese input tasks.

The present invention is more convenient for inputting Japanese text when using a hardware keyboard in a PDA than when using a software keyboard, but can be applied to solve the problem of poor portability.

With the spread of digital television, demands for television shopping, television applications, and the like are increasing, and the present invention can be applied to solving Japanese input problems in such cases.
