Abstract

A Hangul input device (10) has a display unit (11), a detection unit (12), a display control unit (13), and a switching control unit (14). The detection unit detects operations in a display area of the display unit. The display control unit (13) displays either a consonant input screen or a vowel input screen on the display unit when inputting Hangul. The consonant input screen receives input specifying an initial consonant or a final consonant according to either the presence or absence of a slide operation or a difference in a slide direction. The switching control unit (14) performs control in such a manner that the display unit switches to the vowel input screen if an operation specifying an initial consonant is detected in any of the divisional areas of the consonant input screen.

Description

ハングル文字入力装置、ハングル文字入力プログラム、ハングル文字入力方法および入力制御プログラムHangul character input device, Hangul character input program, Hangul character input method and input control program
　本発明は、ハングル文字入力装置、ハングル文字入力プログラム、ハングル文字入力方法および入力制御プログラムに関する。 The present invention relates to a Korean character input device, a Korean character input program, a Korean character input method, and an input control program.
　ハングル文字は、韓国語の音節を表す表音文字であり、一個のハングル文字が一音節を表す。各ハングル文字は、子音や母音を表す複数の記号であるハングル字母を組み合わせることにより構成される。ハングル字母は、先頭の子音を表す初音字母、母音を表す中音字母、および末尾の子音を表す終音字母に分類される。初音字母と終音字母は、記号の形が同じであり、ハングル文字を組み立てるときの位置が異なる。 Hangul characters are phonetic characters representing Korean syllables, and one Hangul character represents one syllable. Each Hangul character is configured by combining Hangul characters that are a plurality of symbols representing consonants and vowels. The Hangul alphabet is classified into an initial alphabet that represents the first consonant, a middle alphabet that represents the vowel, and a final alphabet that represents the last consonant. Hatsune and last moji have the same symbol shape and different positions when assembling Korean characters.
　ハングル文字は、大きく２種類に分類できる。１つは、初音字母と中音字母とを組み合わせた終音なしハングル文字である。もう１つは、初音字母と中音字母と終音字母とを組み合わせた終音ありハングル文字である。 ¡Hangul characters can be roughly classified into two types. One is a Hangul character without end sound that is a combination of an initial and a middle letter. The other is a Hangul character with a ending sound that is a combination of an initial, a middle, and a ending.
　従来、ハングル文字の入力方法として、利用者が初音字母、中音字母、終音字母の順にハングル字母を入力し、プログラムが入力されたハングル字母をハングル文字に変換する方法が知られている。例えば、パソコンなどでは、キーボードの各キーに、初音字母や終音字母を表す子音字母、母音を表す母音字母を割り当てる。利用者は、キーボードを用いて初音字母、中音字母、終音字母の順に入力する。パソコンに搭載されたプログラムは、入力された字母をハングル文字に変換する。 Conventionally, as a method for inputting Hangul characters, a method is known in which a user inputs Hangul characters in the order of the initial character, the middle character, and the last character, and the Hangul character in which the program is input is converted to a Hangul character. For example, in a personal computer or the like, a consonant character that represents an initial phonetic character or a final character and a vowel character that represents a vowel are assigned to each key of the keyboard. The user uses the keyboard to input the first phonetic alphabet, the middle alphabet, and the last alphabet. The program installed on the personal computer converts the input characters to Hangul characters.
　ところで、例えば、携帯電話機など入力ボタンの数が少ない機器には、ハングル字母をさらに細かく分解した要素で入力させる機器がある。これは、ハングル字母を分解した要素の種類が、ハングル字母の種類よりも少なくなり、数少ない入力ボタンに割り当てやすいからである。 By the way, for example, a device with a small number of input buttons such as a mobile phone has a device that allows input using elements obtained by further disassembling the Korean character. This is because the types of elements obtained by disassembling the Hangul alphabet are fewer than the types of the Hangul alphabet and are easily assigned to a few input buttons.
　また、他のハングル文字の入力方法として、３列のボタンのうち、中央の列のボタンに母音を割り当て、両端の列のボタンに子音を割り当ててハングル文字の入力を行う技術が提案されている。 As another Korean character input method, a technique has been proposed in which, among three buttons, a vowel is assigned to the button in the center column and a consonant is assigned to the buttons in both ends to input Korean characters. .
特開２００１－８４０８６号公報JP 2001-84086 A
　しかしながら、携帯電話機などで従来使われているハングル文字の入力方法は、入力ボタンの数がハングル文字の字母の種類と比べて少ないために、一つの字母の入力に複数回の操作が必要となる場合がある。 However, the traditional Korean input method for mobile phones, etc., requires a number of operations to input one character because the number of input buttons is smaller than the number of characters used for Korean characters. There is a case.
　また、提案されたハングル文字の入力方法でも、ハングル文字を入力する際のタッチ操作の回数が多く、効率よく入力できない。例えば、５行３列のキー配列の場合、１つのハングル文字を入力には、最大で、初音字母の入力に３回、中音字母の入力に３回、終音字母の入力に３回、変換指定に１回の計１０回のタッチ操作を必要とする。また、４行３列のキー配列の場合、１つのハングル文字を入力には、最大で、初音字母の入力に３回、中音字母の入力に４回、終音字母の入力に４回、変換指定に１回の計１２回のタッチ操作を必要とする。 Also, even with the proposed input method of Korean characters, the number of touch operations when inputting Korean characters is large and input is not efficient. For example, in the case of a 5-row, 3-column key arrangement, to input one Hangul character, up to 3 times for the input of the first phonetic character, 3 times for the input of the middle character, 3 times for the input of the last character, A total of 10 touch operations are required to designate conversion. In the case of a 4-row, 3-column key arrangement, the maximum number of input for one Hangul character is 3 for the input of the first letter, 4 for the input of the middle letter, and 4 for the input of the last letter. A total of 12 touch operations are required for conversion designation.
　開示の技術は、ハングル文字入力において、入力操作回数を抑制することを目的とする。 The disclosed technology aims to reduce the number of input operations in Korean character input.
　本願の開示するハングル文字入力装置は、一つの態様において、表示部と、検出部と、表示制御部と、切替制御部とを有する。検出部は、表示部の表示領域に対する操作を検出する。表示制御部は、子音入力画面、および母音入力画面の何れかを表示部に表示させる制御を行う。子音入力画面は、表示領域を区分した各区分領域にハングル文字の子音を表す字母をそれぞれ表示し、区分領域に対するスライド操作の有無、スライド方向の違いの何れかにより頭子音または末子音を指定する入力を受け付ける。母音入力画面は、母音を表す字母の入力を受け付ける。切替制御部は、検出部により、子音入力画面の何れかの区分領域に対して頭子音を指定する操作を検出した場合、表示部に表示される画面を母音入力画面に切り替えように表示制御部を制御する。 In one aspect, the Hangul character input device disclosed in the present application includes a display unit, a detection unit, a display control unit, and a switching control unit. The detection unit detects an operation on the display area of the display unit. The display control unit performs control to display either the consonant input screen or the vowel input screen on the display unit. On the consonant input screen, the alphabet that represents the consonant of the Hangul character is displayed in each segmented area, and the head consonant or the final consonant is specified depending on whether there is a slide operation on the segmented area or the difference in the sliding direction. Accept input. The vowel input screen accepts input of a letter representing a vowel. The switching control unit is configured to switch the screen displayed on the display unit to the vowel input screen when the detecting unit detects an operation for designating a head consonant for any of the divided regions of the consonant input screen. To control.
　１態様によれば、ハングル文字の入力における操作回数を抑制できる。 According to the first aspect, the number of operations in inputting Korean characters can be suppressed.

　以下に、本願の開示するハングル文字入力装置、ハングル文字入力プログラム、ハングル文字入力方法および入力制御プログラムの各実施例を図面に基づいて詳細に説明する。なお、各実施例は開示の技術を限定するものではない。そして、各実施例は、処理内容を矛盾させない範囲で適宜組み合わせることが可能である。 Hereinafter, embodiments of the Korean character input device, the Korean character input program, the Korean character input method, and the input control program disclosed in the present application will be described in detail with reference to the drawings. Each embodiment does not limit the disclosed technology. Each embodiment can be appropriately combined within a range in which processing contents are not contradictory.
　まず、本発明の適用対象であるハングル文字入力について説明する。 First, the Korean character input to which the present invention is applied will be described.
　ハングル文字入力について、例えば、携帯電話機などに設けられた４行３列のボタンにハングル字母を割り当てた一例を説明する。図２１は、４行３列のボタンにハングル字母を割り当てた一例を示す図である。図２１の例では、４行３列の１２個のボタン４００のうち、１行目の３つのボタン４００ａ～４００ｃに母音を表す字母を分解した３つの要素を割り当てている。また、図２１の例では、２～４行目の７つのボタン４００ｄ～４００ｋに子音を表す字母を複数割り当てている。各ボタン４００には、割り当てた要素または字母が表記されている。 Regarding Korean character input, for example, an example in which a Korean character is assigned to a 4 × 3 button provided on a mobile phone or the like will be described. FIG. 21 is a diagram showing an example in which a Hangul alphabet is assigned to a 4 × 3 button. In the example of FIG. 21, among the 12 buttons 400 in 4 rows and 3 columns, three elements 400 a to 400 c in the first row are assigned three elements obtained by disassembling the letter representing the vowel. In the example of FIG. 21, a plurality of letters representing consonants are assigned to the seven buttons 400d to 400k on the second to fourth lines. In each button 400, an assigned element or letter is written.
　子音の入力は、ボタン４００ｄ～４００ｋから入力する子音の字母が割り当てられたボタン４００を指定することにより行う。ボタン４００ｄ～４００ｋに割り当てられた字母は、指定された回数に応じて順次表示される。図２２Ａは、子音の入力の一例を示す図である。図２２Ａの例では、ボタン４００ｆを１回から３回指定した場合の選択される字母を示している。母音の入力は、入力する母音の字母を構成する要素の順にボタン４００ａ～４００ｃを指定することにより行う。図２２Ｂは、母音の入力の一例を示す図である。なお、ボタン４００の並び順は、入力順を示している。図２２Ｂの例では、ボタン４００ａ、４００ｂを順に指定した場合と、ボタン４００ｂ、４００ａを順に指定した場合と、ボタン４００ｂ、４００ｃを順に指定した場合に構成される字母を示している。 The consonant is input by designating the button 400 to which the consonant letter input from the buttons 400d to 400k is assigned. Letters assigned to the buttons 400d to 400k are sequentially displayed according to the designated number of times. FIG. 22A is a diagram illustrating an example of consonant input. In the example of FIG. 22A, a selected letter is shown when the button 400f is designated once to three times. The input of vowels is performed by designating buttons 400a to 400c in the order of the elements constituting the vowel letters to be input. FIG. 22B is a diagram illustrating an example of vowel input. Note that the arrangement order of the buttons 400 indicates the input order. In the example of FIG. 22B, characters that are configured when the buttons 400 a and 400 b are sequentially specified, when the buttons 400 b and 400 a are sequentially specified, and when the buttons 400 b and 400 c are sequentially specified are illustrated.
　利用者は、初音字母、中音字母、または初音字母、中音字母、終音字母を順に指定することによりハングル文字の入力を行う。図２３は、ハングル文字の入力操作の一例を示す図である。図２３の例では、ハングル文字４１０の初音字母を入力するには、ボタン４００ｄに３回タッチ操作を行う。また、ハングル文字４１０の中音字母を入力するには、ボタン４００ｃ、ボタン４００ｂ、ボタン４００ｂ、ボタン４００ａ、ボタン４００ａの順にタッチ操作を行う。また、ハングル文字４１０の終音字母を入力するには、ボタン４００ｈに３回タッチ操作を行う。よって、ハングル文字４１０を入力するには、初音字母の入力に３回、中音字母の入力に５回、終音字母の入力に３回の計１１回のボタン４００へのタッチ操作を行う。また、ハングル文字４２０の初音字母を入力するには、ボタン４００ｄに２回タッチ操作を行う。また、ハングル文字４２０の中音字母を入力するには、ボタン４００ｃ、ボタン４００ｂ、ボタン４００ｂ、ボタン４００ａ、ボタン４００ａの順にタッチ操作を行う。また、ハングル文字４２０の終音字母を入力するには、ボタン４００ｅに２回、ボタン４００ｈに２回タッチ操作を行う。よって、ハングル文字４２０を入力するには、初音字母の入力に２回、中音字母の入力に５回、終音字母の入力に４回の計１１回のボタン４００へのタッチ操作を行う。 The user inputs the Hangul character by designating the first letter, middle letter, or first letter, middle letter, and last letter. FIG. 23 is a diagram illustrating an example of a Korean character input operation. In the example of FIG. 23, in order to input the initial phonetic character of the Hangul character 410, the button 400d is touched three times. In order to input the middle letter of the Hangul character 410, the touch operation is performed in the order of the button 400c, the button 400b, the button 400b, the button 400a, and the button 400a. In order to input the last character of the Hangul character 410, the button 400h is touched three times. Therefore, in order to input the Hangul character 410, the touch operation to the button 400 is performed 11 times in total, 3 times for the input of the first character, 5 times for the input of the middle character and 3 times for the input of the last character. In addition, to input the initial phonetic character of the Hangul character 420, the button 400d is touched twice. In order to input the middle letter of the Hangul character 420, the touch operation is performed in the order of the button 400c, the button 400b, the button 400b, the button 400a, and the button 400a. In order to input the last character of the Hangul character 420, a touch operation is performed twice on the button 400e and twice on the button 400h. Therefore, in order to input the Hangul character 420, the touch operation to the button 400 is performed a total of 11 times, twice for the input of the first character, five times for the input of the middle character and four times for the input of the last character.
　また、他のハングル文字の入力方法として、３列のボタンのうち、中央の列のボタンに母音を割り当て、両端の列のボタンに子音を割り当ててハングル文字の入力を行う技術が提案されている。提案されたハングル文字の入力方法でも、ハングル文字を入力する際のタッチ操作の回数が多く、効率よく入力できない。例えば、５行３列のキー配列の場合、１つのハングル文字を入力には、最大で、初音字母の入力に３回、中音字母の入力に３回、終音字母の入力に３回、変換指定に１回の計１０回のタッチ操作を必要とする。また、４行３列のキー配列の場合、１つのハングル文字を入力には、最大で、初音字母の入力に３回、中音字母の入力に４回、終音字母の入力に４回、変換指定に１回の計１２回のタッチ操作を必要とする。 As another Korean character input method, a technique has been proposed in which, among three buttons, a vowel is assigned to the button in the center column and a consonant is assigned to the buttons in both ends to input Korean characters. . Even with the proposed input method of Korean characters, the number of touch operations when inputting Korean characters is large and input is not efficient. For example, in the case of a 5-row, 3-column key arrangement, to input one Hangul character, up to 3 times for the input of the first phonetic character, 3 times for the input of the middle character, 3 times for the input of the last character, A total of 10 touch operations are required to designate conversion. In the case of a 4-row, 3-column key arrangement, the maximum number of input for one Hangul character is 3 for the input of the first letter, 4 for the input of the middle letter, and 4 for the input of the last letter. A total of 12 touch operations are required for conversion designation.
　以下、本発明の実施例について説明する。 Hereinafter, examples of the present invention will be described.
　実施例１に係るハングル文字入力装置１０について説明する。図１は、ハングル文字入力装置１０の機能的な構成の一例を示す図である。図１に示すように、ハングル文字入力装置１０は、表示部１１と、検出部１２と、表示制御部１３と、切替制御部１４とを有する。ハングル文字入力装置１０は、少なくとも利用者がハングル文字の入力が可能された機器であり、例えば、コンピュータや、携帯電話器、スマートフォン、ＰＤＡ（Personal　Digital　Assistants）などの携帯端末などである。 The Korean character input device 10 according to the first embodiment will be described. FIG. 1 is a diagram illustrating an example of a functional configuration of the Korean character input device 10. As shown in FIG. 1, the Hangul character input device 10 includes a display unit 11, a detection unit 12, a display control unit 13, and a switching control unit 14. The Hangul character input device 10 is a device in which at least a user can input Hangul characters, and is, for example, a mobile terminal such as a computer, a mobile phone, a smartphone, or a PDA (Personal Digital Assistants).
　表示部１１は、表示領域に各種情報を表示する。例えば、表示部１１は、ハングル文字の入力を行うための入力画面や、入力されたハングル文字、ハングル文字へ変換途中の字母、変換候補とされたハングルの単語や語句などの言葉を表示する。表示部１１のデバイスの一例としては、ＬＣＤ（Liquid　Crystal　Display）などの表示デバイスが挙げられる。 The display unit 11 displays various information in the display area. For example, the display unit 11 displays an input screen for inputting a Korean character, an input Korean character, a character in the middle of conversion to the Korean character, a word such as a Korean word or phrase that is a conversion candidate. An example of the device of the display unit 11 is a display device such as an LCD (Liquid Crystal Display).
　検出部１２は、表示部１１の表示領域に対する操作を検出する。例えば、検出部１２は、表示部１１の表示領域に対するスライド操作の有無、スライド方向を検出する。スライド操作の有無は、例えば、接触開始位置と接触終了位置の距離が所定の閾値以上であるか否かにより検出される。また、スライド方向は、例えば、接触開始位置と接触終了位置を結んだ直線から移動方向を求めることにより検出される。検出部１２が表示部１１の表示領域への操作を検出する方式は、投影型静電容量方式、表面型静電容量方式、表面弾性波方式、赤外線方式、抵抗膜方式など何れの方式でもよい。なお、図１の例では、機能的な構成を示したため、表示部１１と検出部１２を別に分けているが、例えば、タッチパネルなど表示部１１と検出部１２を一体的に設けたデバイスで構成してもよい。 The detection unit 12 detects an operation on the display area of the display unit 11. For example, the detection unit 12 detects the presence / absence of a slide operation on the display area of the display unit 11 and the slide direction. The presence / absence of the slide operation is detected, for example, based on whether or not the distance between the contact start position and the contact end position is equal to or greater than a predetermined threshold value. The sliding direction is detected by, for example, obtaining the moving direction from a straight line connecting the contact start position and the contact end position. The detection unit 12 may detect any operation on the display area of the display unit 11 by any method such as a projection capacitance method, a surface capacitance method, a surface acoustic wave method, an infrared method, or a resistance film method. . In addition, in the example of FIG. 1, since the functional structure was shown, the display part 11 and the detection part 12 are divided separately, For example, it is comprised with the device which provided the display part 11 and the detection part 12 integrally, such as a touchscreen. May be.
　表示制御部１３は、表示部１１に各種情報を表示させる制御を行う。例えば、表示制御部１３は、ハングル文字の入力を行う際に、子音の入力を行う子音入力画面、および母音の入力を行う母音入力画面の何れかを表示部１１に表示させる制御を行う。子音入力画面は、例えば、表示部１１の表示領域を区分した各区分領域にハングル文字の子音を表す字母をそれぞれ表示する。また、子音入力画面は、区分領域に対するスライド操作の有無、スライド方向の違いの何れかにより頭子音または末子音を指定した入力を受け付ける。母音入力画面も、例えば、表示部１１の表示領域を区分した各区分領域にハングル文字の母音を表す字母をそれぞれ表示し、区分領域に対する操作により字母の入力を受け付ける。 The display control unit 13 performs control to display various information on the display unit 11. For example, the display control unit 13 controls the display unit 11 to display either a consonant input screen for inputting consonants or a vowel input screen for inputting vowels when inputting Korean characters. The consonant input screen displays, for example, letters representing the consonant of the Hangul character in each divided area obtained by dividing the display area of the display unit 11. In addition, the consonant input screen accepts an input designating a head consonant or a final consonant depending on whether or not there is a sliding operation on the segmented region and a difference in the sliding direction. The vowel input screen also displays, for example, characters representing vowels of Korean characters in each divided area obtained by dividing the display area of the display unit 11, and accepts input of the character by an operation on the divided area.
　切替制御部１４は、検出部１２により検出された操作に応じて、表示部１１に表示される画面の切り替えを制御する。例えば、切替制御部１４は、検出部１２により、子音入力画面の何れかの区分領域に対して頭子音を指定する操作を検出された場合、表示部１１に表示される画面を母音入力画面に切り替えるように表示制御部１３を制御する。また、切替制御部１４は、母音入力画面の何れかの区分領域に対して母音を指定する操作を検出した場合、表示部１１に表示される画面を子音入力画面に切り替えるように表示制御部１３を制御する。なお、図１の例では、機能的な構成を示したため、表示制御部１３と切替制御部１４を別に分けているが、例えば、１つのデバイスで構成してもよい。表示制御部１３および切替制御部１４のデバイスの一例としては、ＡＳＩＣ（Application　Specific　Integrated　Circuit）やＦＰＧＡ（Field　Programmable　Gate　Array）などの集積回路が挙げられる。なお、表示制御部１３および切替制御部１４のデバイスとして、ＣＰＵ（Central　Processing　Unit）やＭＰＵ（Micro　Processing　Unit）などの電子回路を採用することができる。 The switching control unit 14 controls switching of the screen displayed on the display unit 11 in accordance with the operation detected by the detection unit 12. For example, when the detection unit 12 detects an operation for designating a head consonant for any of the segmented regions of the consonant input screen, the switching control unit 14 changes the screen displayed on the display unit 11 to the vowel input screen. The display control unit 13 is controlled to switch. In addition, when the switching control unit 14 detects an operation for designating a vowel for any of the divided regions of the vowel input screen, the display control unit 13 switches the screen displayed on the display unit 11 to the consonant input screen. To control. In addition, in the example of FIG. 1, since the functional structure was shown, the display control part 13 and the switching control part 14 are divided separately, However, For example, you may comprise with one device. Examples of the devices of the display control unit 13 and the switching control unit 14 include integrated circuits such as ASIC (Application Specific Integrated Circuit) and FPGA (Field Programmable Gate Array). Note that an electronic circuit such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) can be employed as a device for the display control unit 13 and the switching control unit 14.
　上述してきたように、ハングル文字入力装置１０は、ハングル文字の入力を行う際に、子音の入力を行う子音入力画面、および母音の入力を行う母音入力画面の何れかを表示部１１に表示させる。すなわち、表示部１１には、子音入力画面と母音入力画面の何れか一方が選択的に表示される。このように、子音入力画面と母音入力画面により、子音を表す字母と母音を表す字母を別の画面に表示することで、子音及び母音を表す字母を共に１つの画面で表示させた場合と比較して、画面に表示せる字母の数を少なく抑えることができる。これにより、表示領域が小さい携帯端末でも区分領域のサイズを大きくすることができるため、字母の指定が行ない易くなる。また、例えば、画面に設けた４行３列など一定数の区分領域に字母を表示させる場合においても、子音及び母音を表す字母を共に表示させる場合と比較して、子音入力画面では子音を表す字母を多く表示でき、母音入力画面では母音を表す字母を多く表示できる。 As described above, the Hangul character input device 10 causes the display unit 11 to display either a consonant input screen for inputting a consonant or a vowel input screen for inputting a vowel when inputting a Hangul character. . In other words, either one of the consonant input screen and the vowel input screen is selectively displayed on the display unit 11. In this way, the consonant input screen and the vowel input screen are used to display the consonant and vowel characters on a separate screen, so that both the consonant and vowel characters are displayed on one screen. Thus, the number of characters displayed on the screen can be reduced. Accordingly, since the size of the segmented area can be increased even with a mobile terminal having a small display area, it is easy to specify the character. Also, for example, when displaying a letter in a certain number of segmented areas such as 4 rows and 3 columns provided on the screen, a consonant is displayed on the consonant input screen as compared to a case where a letter representing a consonant and a vowel is displayed together. Many characters can be displayed, and many characters representing vowels can be displayed on the vowel input screen.
　また、ハングル文字入力装置１０は、子音入力画面の何れかの区分領域に対して頭子音を指定する操作が行われた場合、表示部１１に表示される画面を母音入力画面に切り替える。すなわち、ハングル文字入力装置１０は、子音入力画面で頭子音を指定する操作が行われた場合、母音入力画面が表示される。ここで、ハングル文字は、初音字母および終音字母が共に子音であるため、子音が入力されても次に指定されるべき字母が子音であるか母音である特定できない。そこで、本実施例に係るハングル文字入力装置１０は、子音入力画面から子音の入力を行う際の区分領域に対するスライド操作の有無、スライド方向の違いの何れかにより頭子音または末子音を指定した入力を受け付ける。そして、ハングル文字入力装置１０は、頭子音を指定する操作が行われた場合、表示部１１に母音入力画面が表示される。したがって、本実施例に係るハングル文字入力装置１０によれば、利用者が画面の切り替えを指示することなく、母音入力画面が表示されるため、ハングル文字を効率良く入力でき、ハングル文字の入力における操作回数を抑制できる。 In addition, the Hangul character input device 10 switches the screen displayed on the display unit 11 to the vowel input screen when an operation for designating a head consonant is performed on any of the segmented regions of the consonant input screen. That is, the Hangul character input device 10 displays a vowel input screen when an operation for designating a head consonant is performed on the consonant input screen. Here, in the Hangul character, both the initial and final vowels are consonants, so even if a consonant is input, it cannot be specified whether the next character to be specified is a consonant or a vowel. Therefore, the Hangul character input device 10 according to the present embodiment is an input in which a head consonant or a final consonant is designated depending on either the presence or absence of a sliding operation on a segmented region when a consonant is input from the consonant input screen, or a difference in sliding direction. Accept. When the operation for designating a head consonant is performed, the hangul character input device 10 displays a vowel input screen on the display unit 11. Therefore, according to the Hangul character input device 10 according to the present embodiment, since the vowel input screen is displayed without the user instructing to switch the screen, the Hangul character can be input efficiently. The number of operations can be suppressed.
　次に、実施例２について説明する。実施例２では、携帯端末からハングル文字を入力する場合を説明する。図２は、携帯端末２０の表面形状を示す平面図である。携帯端末２０は、各種情報の表示および表示領域への各種操作を検出が可能なタッチパネル２１を有する。図２の例では、ハングル文字を入力する際にタッチパネル２１に表示されるハングル入力画面の一例が示されている。ハングル文字の入力を行う際、タッチパネル２１には、入力部２２と、入力結果表示部２３と、入力候補表示部２６とが表示される。 Next, Example 2 will be described. In the second embodiment, a case where Korean characters are input from a mobile terminal will be described. FIG. 2 is a plan view showing the surface shape of the mobile terminal 20. The portable terminal 20 has a touch panel 21 that can display various information and detect various operations on the display area. In the example of FIG. 2, an example of a Korean input screen displayed on the touch panel 21 when inputting Korean characters is shown. When inputting Korean characters, the touch panel 21 displays an input unit 22, an input result display unit 23, and an input candidate display unit 26.
　入力部２２は、４行３列に区分されており、各区分領域がそれぞれ入力を受け付けるボタン２４として機能する。各ボタン２４には、それぞれ字母が割り当てられており、割り当てられた字母が表示される。入力結果表示部２３は、入力部２２から入力されたハングル文字やハングル文字へ変換途中の字母が表示される。入力候補表示部２６は、２行３列に区分されており、各区分領域に入力候補の言葉が並べて表示される。 The input unit 22 is divided into 4 rows and 3 columns, and each divided region functions as a button 24 for receiving input. A letter is assigned to each button 24, and the assigned letter is displayed. The input result display unit 23 displays Korean characters input from the input unit 22 and characters in the middle of conversion to Korean characters. The input candidate display unit 26 is divided into 2 rows and 3 columns, and words of input candidates are displayed side by side in each divided region.
　携帯端末２０は、ハングル文字の入力に関して複数の動作モードを有する。例えば、携帯端末２０は、ハングル文字の子音を入力する子音入力モードと、ハングル文字の母音を入力する母音入力モードとを有する。子音入力モードでは、入力部２２の各ボタン２４に子音を表す字母を表示した子音入力画面をタッチパネル２１に表示させる。また、子音入力モードでは、ボタン２４に対するスライド操作の有無、スライド方向の違いの何れかにより頭子音または末子音を指定した入力を受け付ける。母音入力モードでは、入力部２２の各ボタン２４に母音を表す字母を表示した母音入力画面をタッチパネル２１に表示させる。また、母音入力モードでは、各ボタン２４に対する操作により母音の入力を受け付ける。なお、入力部２２の各ボタン２４は、ハングル文字の入力のみに用いるものではなく、数字を割り当てて数字ボタンとしても用いてもよい。図３は、入力部２２の各ボタン２４に数字を割り当てた場合の一例を示す図である。図３の例では、１行目の３つのボタン２４のそれぞれに、数字「１」、「２」、「３」のそれぞれが割り当てられた場合が示されている。また、図３の例では、２行目の３つのボタン２４のそれぞれに、数字「４」、「５」、「６」のそれぞれが割り当てられた場合が示されている。また、図３の例では、３行目の３つのボタン２４のそれぞれに、数字「７」、「８」、「９」のそれぞれが割り当てられた場合が示されている。また、図３の例では、４行目のボタン２４に、数字「０」が割り当てられた場合が示されている。 The mobile terminal 20 has a plurality of operation modes for inputting Korean characters. For example, the mobile terminal 20 has a consonant input mode for inputting a consonant of a Hangul character and a vowel input mode for inputting a vowel of a Hangul character. In the consonant input mode, a consonant input screen in which a letter representing a consonant is displayed on each button 24 of the input unit 22 is displayed on the touch panel 21. In the consonant input mode, an input designating the head consonant or the last consonant is accepted depending on whether the button 24 is slid or not and the slide direction is different. In the vowel input mode, a vowel input screen displaying a vowel representing a vowel on each button 24 of the input unit 22 is displayed on the touch panel 21. In the vowel input mode, vowel input is accepted by an operation on each button 24. Note that the buttons 24 of the input unit 22 are not used only for inputting Korean characters, but may be assigned numbers and used as number buttons. FIG. 3 is a diagram illustrating an example when a number is assigned to each button 24 of the input unit 22. In the example of FIG. 3, the numbers “1”, “2”, and “3” are assigned to the three buttons 24 in the first row, respectively. In the example of FIG. 3, the numbers “4”, “5”, and “6” are assigned to the three buttons 24 in the second row. In the example of FIG. 3, the numbers “7”, “8”, and “9” are assigned to the three buttons 24 in the third row, respectively. In the example of FIG. 3, the number “0” is assigned to the button 24 in the fourth row.
　次に、携帯端末２０の機能的な構成を説明する。図４は、携帯端末２０の機能的な構成の一例を示す図である。携帯端末２０は、タッチパネル２１と、記憶部３０、制御部３１とを有している。 Next, the functional configuration of the mobile terminal 20 will be described. FIG. 4 is a diagram illustrating an example of a functional configuration of the mobile terminal 20. The mobile terminal 20 includes a touch panel 21, a storage unit 30, and a control unit 31.
　タッチパネル２１は、表示部１１と、表示部１１の表示領域に対する操作を検出する検出部１２と有する。表示部１１は、制御部３１からの制御により各種情報を表示する。例えば、表示部１１は、制御部３１からの制御により、図２に示した画面を表示する。検出部１２は表示領域に対する操作の検出結果を制御部３１へ出力する。 The touch panel 21 includes a display unit 11 and a detection unit 12 that detects an operation on the display area of the display unit 11. The display unit 11 displays various types of information under the control of the control unit 31. For example, the display unit 11 displays the screen illustrated in FIG. 2 under the control of the control unit 31. The detection unit 12 outputs the detection result of the operation on the display area to the control unit 31.
　記憶部３０は、各種情報を記憶する。例えば、記憶部３０は、割当字母情報３０ａと、定義情報３０ｂと、入力文字記号記憶テーブル３０ｃと、辞書３０ｄとを記憶する。記憶部３０のデバイスの一例としては、フラッシュメモリやＮＶＳＲＡＭ(Non　Volatile　Static　Random　Access　Memory)などのデータを書き換え可能な不揮発性の半導体メモリが挙げられる。 The storage unit 30 stores various information. For example, the storage unit 30 stores assigned character information 30a, definition information 30b, an input character symbol storage table 30c, and a dictionary 30d. As an example of the device of the storage unit 30, there is a non-volatile semiconductor memory capable of rewriting data such as a flash memory or NVSRAM (Non Volatile Static Random Access Memory).
　割当字母情報３０ａには、動作モード毎に、各ボタン２４に割り当てる字母を示す情報が含まれる。ここで、入力部２２の各ボタン２４への字母の割り当てについて説明する。ハングル文字の頭子音または末子音に用いられる字母は、１９種類ある。この１９種類の子音を表す字母は、頭子音または末子音で同じ字母である平音字母、平音字母を縦に二つ並べた形状に近似する激音字母、平音字母を横に二つ並べた形状に近似する濃音字母の３種類に分類できる。図５は、子音を表す字母を分類した結果を示す図である。図５では、各字母の発音のローマ字表記を括弧内に示している。図５に示すように、子音を表す字母は、９個の平音字母と、５個の激音字母と、５個の濃音字母に分類される。 The assigned letter information 30a includes information indicating the letter assigned to each button 24 for each operation mode. Here, the assignment of characters to the buttons 24 of the input unit 22 will be described. There are 19 letters used for the first consonant or the last consonant of a Hangul character. These 19 types of consonants are the first consonant or the last consonant, the same character, the flat character, the two superphonic characters that approximate the shape of two flat characters, and two flat characters. It can be classified into three types of deep tone mothers that approximate the arranged shapes. FIG. 5 is a diagram showing the result of classifying the letters representing consonants. In FIG. 5, the romanized notation of the pronunciation of each letter is shown in parentheses. As shown in FIG. 5, the letters representing consonants are classified into nine flat letters, five gigantic letters, and five concentrated letters.
　また、ハングル文字の母音として用いられる字母は、２１種類ある。この２１種類の母音を表す字母は、発音から、半母音なし字母、半母音ｙ付き字母、半母音ｗ付き字母の３種類に分類できる。図６は、母音を表す字母を分類した結果を示す図である。図６でも、各字母の発音のローマ字表記を括弧内に示している。図６に示すように、母音を表す字母は、１０個の半母音なし字母と、６個の半母音ｙ付き字母と、５個の半母音ｗ付き字母に分類される。 Also, there are 21 types of characters used as vowels for Korean characters. Characters representing these 21 types of vowels can be classified into three types according to pronunciation: a semi-vowelless character, a semi-vowel y-attached character, and a semi-vowel w-attached character. FIG. 6 is a diagram showing the result of classifying the letters representing vowels. Also in FIG. 6, the romanized notation of the pronunciation of each letter is shown in parentheses. As shown in FIG. 6, the vowels representing the vowels are classified into 10 semi-vowelless vowels, 6 semi-vowel y-attached letters, and 5 semi-vowel w-attached letters.
　本実施例では、入力部２２の１２個のボタン２４のうち、９個のボタンに対してそれぞれに平音字母と、平音字母に対応する濃音字母、激音字母を割り当てている。図７Ａは、入力部２２の各ボタン２４に割り当てた平音字母、濃音字母、激音字母の一例を示す図である。また、本実施例では、入力部２２の１２個のボタン２４のうち、１０個のボタンに対してそれぞれ半母音なし字母と半母音なし字母に対応する半母音ｙ付き字母、半母音ｗ付き字母を割り当てている。図７Ｂは、入力部２２の各ボタン２４に割り当てた半母音なし字母、半母音ｙ付き字母、半母音ｗ付き字母の一例を示す図である。 In the present embodiment, among the 12 buttons 24 of the input unit 22, 9 characters are assigned to each of the 9 characters, the hiragana character and the strong tone character corresponding to the hiragana character. FIG. 7A is a diagram illustrating an example of a flat ontograph, a deep onset, and an overtone base assigned to each button 24 of the input unit 22. Further, in the present embodiment, of the twelve buttons 24 of the input unit 22, the ten vowel-less letters and the half-vowel-less letters corresponding to the half-vowel-less letters and the half-vowel w-named letters are assigned to the ten buttons. . FIG. 7B is a diagram illustrating an example of a letter without semi-vowel, a letter with semi-vowel y, and a letter with semi-vowel w assigned to each button 24 of the input unit 22.
　図４の説明に戻り、制御部３１は、ハングル文字の入力に関する各種制御を行う。制御部３１のデバイスの一例としては、ＡＳＩＣやＦＰＧＡなどの集積回路またはＣＰＵやＭＰＵなどの電子回路が挙げられる。図４に示すように、制御部３１は、操作判別部３１ａと、表示制御部３１ｂと、切替制御部３１ｃと、文字種判別部３１ｄ、文字変換部３１ｅと、検索部３１ｆとを有する。 Referring back to the description of FIG. 4, the control unit 31 performs various controls related to the input of Hangul characters. As an example of the device of the control unit 31, an integrated circuit such as an ASIC or FPGA or an electronic circuit such as a CPU or MPU can be cited. As shown in FIG. 4, the control unit 31 includes an operation determination unit 31a, a display control unit 31b, a switching control unit 31c, a character type determination unit 31d, a character conversion unit 31e, and a search unit 31f.
　操作判別部３１ａは、検出部１２による検出結果に基づき、入力部２２の何れかのボタン２４にタッチ操作が行われたかを検出する。また、操作判別部３１ａは、ボタン２４へのタッチ操作が検出された場合、スライド操作の有無を検出する。スライド操作の有無は、例えば、接触開始位置と接触終了位置の距離が所定の閾値以上であるか否かを判定することにより検出される。また、操作判別部３１ａは、スライド操作を検出した場合、スライド方向を検出する。図８は、検出するスライド方向の一例を示す図である。図８に示すように、操作判別部３１ａは、スライド方向が上、左上、左、左下、下、右下、右、右上の８方向の何れかであるかを検出する。スライド方向の検出は、例えば、移動方向が８方向の何れにもっと近いかを判定することにより行う。 The operation determination unit 31 a detects whether a touch operation has been performed on any button 24 of the input unit 22 based on the detection result by the detection unit 12. Further, the operation determination unit 31a detects the presence / absence of a slide operation when a touch operation on the button 24 is detected. The presence / absence of the slide operation is detected, for example, by determining whether the distance between the contact start position and the contact end position is equal to or greater than a predetermined threshold. Moreover, the operation determination part 31a detects a slide direction, when a slide operation is detected. FIG. 8 is a diagram illustrating an example of a slide direction to be detected. As illustrated in FIG. 8, the operation determination unit 31 a detects whether the slide direction is any one of eight directions, that is, upper, upper left, left, lower left, lower, lower right, right, and upper right. The detection of the sliding direction is performed, for example, by determining which of the eight directions the moving direction is closer to.
　表示制御部３１ｂは、子音入力モードにおいて、何れのボタン２４にもタッチ操作が行われていない場合、割当字母情報３０ａに基づき、それぞれに割り当てられた平音字母を各ボタン２４に表示させる。また、表示制御部３１ｂは、母音入力モードにおいて、何れのボタン２４にもタッチ操作が行われていない場合、割当字母情報３０ａに基づき、それぞれに割り当てられた半母音なし字母を各ボタン２４に表示させる。 When the touch operation is not performed on any of the buttons 24 in the consonant input mode, the display control unit 31b causes each button 24 to display the flat character assigned to each button 24 based on the assigned character information 30a. In addition, in the vowel input mode, the display control unit 31b causes each button 24 to display a semi-vowel-less character assigned to each button 24 based on the assigned character information 30a when any button 24 is not touched. .
　また、表示制御部３１ｂは、子音入力モード及び母音入力モードにおいて、何れかのボタン２４がタッチ操作された場合、選択領域２５を新たに表示させる。定義情報３０ｂには、動作モード毎に、選択領域２５にどのような情報を表示するかを定義する情報が含まれている。 In addition, the display control unit 31b newly displays the selection area 25 when any button 24 is touched in the consonant input mode and the vowel input mode. The definition information 30b includes information that defines what information is displayed in the selection area 25 for each operation mode.
　図９Ａは、子音入力モードの定義情報を模式的に示した図である。図９Ａの例では、タッチ操作されたボタン２４を中心に上、左上、左、左下、下、右下、右、右上の８方向に選択領域２５を設けることが定義されている。また、図９Ａの例では、ボタン２４に平音字母を表示し、左右の選択領域２５に濃音字母、激音字母を表示することが定義されている。また、図９Ａの例では、上下方向に、平音字母、濃音字母、激音字母について、頭子音のみ指定する頭子音のみ入力、頭子音の指定後に組み合わせる母音を指定する頭子音標準入力、末子音を指定する末子音入力の何れを行うかが定義されている。 FIG. 9A is a diagram schematically showing the definition information of the consonant input mode. In the example of FIG. 9A, it is defined that selection areas 25 are provided in eight directions, namely, upper, upper left, left, lower left, lower, lower right, right, and upper right, with the button 24 being touch-operated. Further, in the example of FIG. 9A, it is defined that a flat character is displayed on the button 24 and a deep character and a strong character are displayed on the left and right selection areas 25. Further, in the example of FIG. 9A, in the up and down direction, for the consonant standard input for designating the vowels to be combined after the designation of the head consonant, the head consonant only for the head consonant, the head consonant to be designated after the head consonant is designated, It is defined which end consonant input that specifies the end consonant is performed.
　図９Ｂは、母音入力モードの定義情報を模式的に示した図である。図９Ｂの例でも、タッチ操作されたボタン２４を中心に上、左上、左、左下、下、右下、右、右上の８方向に選択領域２５を設けることが定義されている。また、図９Ｂの例では、ボタン２４に半母音なし字母を表示し、左右の選択領域２５に半母音ｙ付き字母、半母音ｗ付き字母を表示することが定義されている。また、図９Ｂの例では、上下の選択領域２５については未定義とされている。図９Ｂの例では、上方向にスライドする場合と下方向にスライドする場合については特に定義を行っていない。このように、選択領域２５にどのような情報を表示するかを定義することにより、利用者が自由に表示を変更できる。また、本実施例では、図９Ａに示すように、上方向のスライドに頭子音のみの入力に割り当て、下方向のスライドを末子音の入力に割り当てているため、ハングル文字や字母の構造などから容易に指定内容を連想できる。 FIG. 9B is a diagram schematically showing the definition information of the vowel input mode. Also in the example of FIG. 9B, it is defined that the selection areas 25 are provided in eight directions of the upper, upper left, left, lower left, lower, lower right, right, and upper right with the touch-operated button 24 as the center. In the example of FIG. 9B, it is defined that the button 24 displays a character without a semi-vowel, and the left and right selection areas 25 display a character with a semi-vowel y and a character with a semi-vowel w. In the example of FIG. 9B, the upper and lower selection areas 25 are not defined. In the example of FIG. 9B, no particular definition is given for the case of sliding upward and the case of sliding downward. In this way, by defining what information is displayed in the selection area 25, the user can freely change the display. Further, in this embodiment, as shown in FIG. 9A, since only the first consonant input is assigned to the upward slide and the downward slide is assigned to the last consonant input, You can easily associate the specified contents.
　表示制御部３１ｂは、子音入力モードにおいて、入力部２２の各ボタン２４にタッチ操作が行われていない場合、選択領域２５を表示させず、各ボタン２４に平音字母を表示させる。図１０Ａは、タッチ操作されていない状態での入力部の表示状態の一例を示す図である。図１０Ａの例では、各ボタン２４に平音字母が表示されている。 When the touch operation is not performed on each button 24 of the input unit 22 in the consonant input mode, the display control unit 31b does not display the selection area 25 but displays the phonetic alphabet on each button 24. FIG. 10A is a diagram illustrating an example of a display state of the input unit when no touch operation is performed. In the example of FIG. 10A, a flat alphabet is displayed on each button 24.
　また、表示制御部３１ｂは、子音入力モードにおいて、入力部２２のボタン２４の何れかがタッチ操作された場合、選択領域２５を表示させ、定義情報３０ｂに従い、表示を行う。図１０Ｂ～１０Ｊには、図９Ａに示す定義情報３０ｂに従い、ボタン２４ａ～２４ｉにタッチ操作が行われた状態での入力部２２の表示状態の一例が示されている。なお、図１０Ｂは、ボタン２４ａがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｃは、ボタン２４ｂがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｄは、ボタン２４ｃがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｅは、ボタン２４ｄがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｆは、ボタン２４ｅがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｇは、ボタン２４ｆがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｈは、ボタン２４ｇがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｉは、ボタン２４ｈがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１０Ｊは、ボタン２４ｉがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。 In addition, when any of the buttons 24 of the input unit 22 is touched in the consonant input mode, the display control unit 31b displays the selection area 25 and performs display according to the definition information 30b. FIGS. 10B to 10J show an example of the display state of the input unit 22 when the buttons 24a to 24i are touched in accordance with the definition information 30b shown in FIG. 9A.

FIG. 10J is a diagram illustrating an example of a display state of the input unit 22 in a state where the button 24i is touch-operated.
　また、本実施例では、子音入力モードにおいて、子音の字母以外に、子音、母音を任意とすることを指定するため、一部のボタン２４に特殊記号を表示する。図１０ｃの例では、特殊記号として「＊」、「＊＊」、「＃」、「＃＃」を表示している。この特殊記号「＊」は、頭子音の入力を省略して頭子音を任意とし、母音を指定する頭子音任意母音入力を行うことを意味する。特殊記号「＊＊」は、頭子音の入力を複数文字分省略して複数文字分の頭子音を任意とし、母音を指定する頭子音任意母音入力を行うことを意味する。特殊記号「＃」は、頭子音の入力を省略して頭子音を任意とし、次の子音の指定する頭子音省略入力を行うことを意味する。特殊記号「＃＃」は、頭子音の入力を複数文字分省略して複数文字分の頭子音を任意とし、次の子音の指定する頭子音省略入力を行うことを意味する。なお、本実施例では、「＊＊」および「＃＃」は、頭子音の入力を２文字分省略するものとする。 Also, in this embodiment, in the consonant input mode, a special symbol is displayed on some buttons 24 in order to specify that consonants and vowels are arbitrary in addition to the consonant letters. In the example of FIG. 10c, “*”, “**”, “#”, and “##” are displayed as special symbols. The special symbol “*” means that the head consonant is input by omitting the input of the head consonant, and the head consonant arbitrary vowel input for designating the vowel is performed. The special symbol “**” means that an initial vowel input specifying a vowel is performed by omitting a plurality of characters of initial consonant input and making an arbitrary number of initial consonant sounds. The special symbol “#” means that the head consonant input is omitted by omitting the input of the head consonant, and the head consonant skip input designated by the next consonant is performed. The special symbol “##” means that the head consonant input is omitted by a plurality of characters, the head consonant for a plurality of characters is made arbitrary, and the head consonant skip input designated by the next consonant is performed. In this embodiment, “**” and “##” omit the input of the initial consonant by two characters.
　これにより、スライドせずまたは上下にスライド操作された場合は平音字母の入力と判別できる。また、右方向へスライド操作された場合は激音字母の入力と判別できる。左向方向へスライド操作された場合は濃音字母の入力と判別できる。また、上下にスライドせずに左右にスライド操作された場合は頭子音の標準入力と判別できる。上方向へスライド操作された場合は頭子音のみの入力と判別できる。下方向へスライド操作された場合は末子音の入力と判別できる。 This allows you to distinguish it as an input of the flat character when it is not slid or slid up and down. In addition, when a slide operation is performed in the right direction, it can be determined that the input of a gigantic character is input. When the slide operation is performed in the leftward direction, it can be determined that the input of a deep tone character is input. In addition, when a slide operation is performed left and right without sliding up and down, it can be determined as a standard input of a head consonant. When a slide operation is performed upward, it can be determined that only a head consonant is input. When the slide operation is performed downward, it can be determined that the last consonant is input.
　また、表示制御部３１ｂは、母音入力モードにおいて、入力部２２の各ボタン２４にタッチ操作が行われていない場合、選択領域２５を表示させず、各ボタン２４に半母音なし字母を表示させる。図１１Ａは、タッチ操作されていない状態での入力部２２の表示状態の一例を示す図である。図１１Ａの例では、各ボタン２４に半母音なし字母が表示されている。 Also, in the vowel input mode, the display control unit 31b does not display the selection area 25 and displays a semi-vowelless character on each button 24 when no touch operation is performed on each button 24 of the input unit 22. FIG. 11A is a diagram illustrating an example of a display state of the input unit 22 in a state where a touch operation is not performed. In the example of FIG. 11A, each button 24 displays a semi-vowelless character.
　また、表示制御部３１ｂは、子音入力モードにおいて、入力部２２のボタン２４の何れかがタッチ操作された場合、選択領域２５を表示させ、定義情報３０ｂに従い、表示を行う。図１１Ｂ～１１Ｋには、図９Ｂに示す定義情報３０ｂに従い、ボタン２４ａ～２４ｊにタッチ操作が行われた状態での入力部２２の表示状態の一例が示されている。なお、図１１Ｂは、ボタン２４ａがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｃは、ボタン２４ｂがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｄは、ボタン２４ｃがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｅは、ボタン２４ｄがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｆは、ボタン２４ｅがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｇは、ボタン２４ｆがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｈは、ボタン２４ｇがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｉは、ボタン２４ｈがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｊは、ボタン２４ｉがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｋは、ボタン２４ｊがタッチ操作された状態での入力部２２の表示状態の一例を示す図である。図１１Ｂ～１１Ｋの例では、特に定義を行っていない行について選択領域２５を表示していない。 In addition, when any of the buttons 24 of the input unit 22 is touched in the consonant input mode, the display control unit 31b displays the selection area 25 and performs display according to the definition information 30b. FIGS. 11B to 11K show an example of the display state of the input unit 22 when the buttons 24a to 24j are touched in accordance with the definition information 30b shown in FIG. 9B. FIG. 11B is a diagram illustrating an example of a display state of the input unit 22 in a state where the button 24a is touched.

In the examples of FIGS. 11B to 11K, the selection area 25 is not displayed for the lines that are not particularly defined.
　これにより、スライド操作が無い場合は半母音なし字母の入力と判別できる。右方向へスライド操作された場合は半母音ｙ付き字母の入力と判別できる。左方向へスライド操作された場合は半母音ｗ付き字母の入力と判別できる。 This makes it possible to determine that there is no semi-vowel character input when there is no slide operation. When the slide operation is performed in the right direction, it can be determined that the input is a letter with a semi-vowel y. When a leftward sliding operation is performed, it can be determined that the input is a letter with a semi-vowel w.
　図４の説明に戻り、切替制御部３１ｃは、子音入力モードにおいて、操作判別部３１ａにより検出されたスライド方向から、標準入力および頭子音任意母音入力を指定する操作を検出した場合、表示制御部３１ｂに対して母音入力モードへの切り替えを指示する。また、切替制御部３１ｃは、子音入力モードにおいて、「＊」、「＊＊」が入力された場合、表示制御部３１ｂに対して母音入力モードへの切り替えを指示する。また、切替制御部３１ｃは、子音入力モードにおいて、「＃」、「＃＃」が入力された場合、子音入力モードを維持させる。また、切替制御部３１ｃは、母音入力モードにおいて、操作判別部３１ａにより検出された操作から、母音を指定する操作を検出した場合、表示制御部３１ｂに対して子音入力モードへの切り替えを指示する。また、切替制御部３１ｃは、子音入力モードにおいて、頭子音のみ入力および頭子音省略入力を指定する操作を検出した場合、表示制御部３１ｂに対して切り替えを指示せず、子音入力モードを維持させる。 Returning to the description of FIG. 4, when the switching control unit 31 c detects an operation for designating the standard input and the initial consonant vowel input from the slide direction detected by the operation determination unit 31 a in the consonant input mode, 31b is instructed to switch to the vowel input mode. In addition, in the consonant input mode, the switching control unit 31c instructs the display control unit 31b to switch to the vowel input mode when “*” or “**” is input. In addition, when “#” and “##” are input in the consonant input mode, the switching control unit 31c maintains the consonant input mode. In addition, in the vowel input mode, the switching control unit 31c instructs the display control unit 31b to switch to the consonant input mode when an operation for designating a vowel is detected from the operations detected by the operation determination unit 31a. . Further, in the consonant input mode, the switching control unit 31c does not instruct the display control unit 31b to perform switching and maintains the consonant input mode when detecting an operation of designating only a head consonant input and a head consonant skip input. .
　入力文字記号記憶テーブル３０ｃには、子音入力モードについては、各ボタン２４に対してスライド操作なしおよび８方向のスライド方向が行われた場合に指定される字母、および字母を識別する辞書検索コードが記憶されている。また、入力文字記号記憶テーブル３０ｃには、母音入力モードについては、各ボタン２４に対してスライド操作なし、および左右２方向のスライド方向が行われた場合に指定される字母、および当該字母を識別する辞書検索コードが登録されている。なお、本実施例では、入力文字記号記憶テーブル３０ｃを子音入力モード用と母音入力モード用にテーブルを分けている。また、本実施例では、子音入力モード用の入力文字記号記憶テーブル３０ｃをスライド操作なし、および８方向のスライド方向の操作別に、入力文字記号記憶テーブルＣＵＬ、ＣＵＮ、ＣＵＲ、ＣＮＬ、ＣＮＮ、ＣＮＲ、ＣＤＬ、ＣＤＮ、ＣＤＲと９つに分けている。また、本実施例では、母音入力モード用の入力文字記号記憶テーブル３０ｃをスライド操作なし、および左右２方向のスライド方向の操作別に、入力文字記号記憶テーブルＶＮＬ、ＶＮＮ、ＶＮＲと３つに分けている。各入力文字記号記憶テーブルに付した１番目の英字は、「Ｃ」が子音入力モード用、「Ｖ」が母音モード用を意味する。また、２番目の英字は、「Ｕ」が上方向のスライド用、「Ｄ」が下方向のスライド用、「Ｎ」がスライドなし用を意味する。また、３番目の英字は、「Ｌ」が左方向のスライド用、「Ｒ」が右方向のスライド用、「Ｎ」がスライドなし用を意味する。 In the input character / symbol storage table 30c, for the consonant input mode, a dictionary search code for identifying a character and a character specified when no sliding operation is performed on each button 24 and eight sliding directions are performed is provided. It is remembered. Further, in the input character symbol storage table 30c, in the vowel input mode, the character designated when no sliding operation is performed on each button 24 and the left and right sliding directions are performed, and the corresponding character are identified. The dictionary search code to be registered is registered. In this embodiment, the input character / symbol storage table 30c is divided into a table for consonant input mode and a vowel input mode. In this embodiment, the input character / symbol storage table 30c for the consonant input mode is not slid, and the input character / symbol storage table CUL, CUN, CUR, CNL, CNN, CNR, CDL, CDN, CDR are divided into nine. In this embodiment, the input character / symbol storage table 30c for the vowel input mode is divided into three as input character / symbol storage tables VNL, VNN, and VNR according to the operation in the sliding direction in the left and right directions without sliding operation. Yes. The first alphabetic character assigned to each input character symbol storage table means “C” for consonant input mode and “V” for vowel mode. The second alphabetic character means “U” for upward sliding, “D” for downward sliding, and “N” for no sliding. The third alphabetic character means “L” for sliding left, “R” for sliding right, and “N” for no sliding.
　図１２Ａ～１２Ｌには、入力文字記号記憶テーブル３０ｃのデータ構造の一例が示されている。図１２Ａの例では、入力文字記号記憶テーブルＣＵＬの一例が示されている。図１２Ｂの例では、入力文字記号記憶テーブルＣＵＮの一例が示されている。図１２Ｃの例では、入力文字記号記憶テーブルＣＵＲの一例が示されている。図１２Ｄの例では、入力文字記号記憶テーブルＣＮＬの一例が示されている。図１２Ｅの例では、入力文字記号記憶テーブルＣＮＮの一例が示されている。図１２Ｆの例では、入力文字記号記憶テーブルＣＮＲの一例が示されている。図１２Ｇの例では、入力文字記号記憶テーブルＣＤＬの一例が示されている。図１２Ｈの例では、入力文字記号記憶テーブルＣＤＮの一例が示されている。図１２Ｉの例では、入力文字記号記憶テーブルＣＤＲの一例が示されている。図１２Ｊの例では、入力文字記号記憶テーブルＶＮＬの一例が示されている。図１２Ｋの例では、入力文字記号記憶テーブルＶＮＮの一例が示されている。図１２Ｌの例では、入力文字記号記憶テーブルＶＮＲの一例が示されている。 12A to 12L show an example of the data structure of the input character symbol storage table 30c.

　文字種判別部３１ｄは、動作モードおよび操作判別部３１ａにより検出されたスライド操作の有無、スライド方向に基づいて、参照対象とする入力文字記号記憶テーブルを特定する。そして、文字種判別部３１ｄは、特定した入力文字記号記憶テーブルの、操作判別部３１ａにより検出されたタッチ操作されたボタン２４の番号に対応するレコードを参照して、指定された字母、および字母の辞書検索コードを特定する。 The character type determination unit 31d specifies the input character symbol storage table to be referred to based on the operation mode, the presence / absence of the slide operation detected by the operation determination unit 31a, and the slide direction. Then, the character type determination unit 31d refers to the record corresponding to the number of the touch-operated button 24 detected by the operation determination unit 31a in the specified input character symbol storage table, and the designated character and the character Identify dictionary search codes.
　文字変換部３１ｅは、特定された字母がハングル文字に変換できる場合はハングル文字に変換する。例えば、文字変換部３１ｅは、頭子音の指定後に組み合わせる母音を指定する頭子音標準入力や頭子音のみ入力が行われた場合、標準入力の直前に入力された子音字母と母音字母または子音字母と母音字母と子音字母の組み合わせをハングル文字に変換する。また、文字変換部３１ｅは、末子音を指定する末子音入力が行われた場合、末子音入力で入力された字母を末子音の字母として、子音字母と母音字母と子音字母の組み合わせをハングル文字に変換する。 The character conversion unit 31e converts the specified character into a Korean character if it can be converted into a Korean character. For example, when a consonant standard input that specifies a vowel to be combined after a head consonant is specified or only a head consonant is input, the character conversion unit 31e receives a consonant character and a vowel character or a consonant character that are input immediately before the standard input. Convert the combination of vowel and consonant mothers to Hangul script. In addition, when a consonant input specifying a consonant is performed, the character conversion unit 31e sets the consonant character, the vowel character, and the consonant character combination to be a Hangul character with the character input in the consonant input as the character of the consonant. Convert to
　辞書３０ｄには、ハングルの複数の言葉が記憶されている。例えば、辞書３０ｄには、使用頻度の高い言葉や、慣用句、単語などが記憶される。また、辞書３０ｄには、言葉の構成するハングル文字毎に、ハングル文字の各字母の辞書検索コードが記憶されている。なお、本実施例では、図１２Ａ～１２Ｌに示すように、頭子音の辞書検索コードと末子音の辞書検索コードを異なるコードにしている。 A plurality of Korean words are stored in the dictionary 30d. For example, the dictionary 30d stores frequently used words, idiomatic phrases, words, and the like. The dictionary 30d stores a dictionary search code for each letter of the Hangul character for each Hangul character constituting the word. In this embodiment, as shown in FIGS. 12A to 12L, the dictionary search code for the head consonant and the dictionary search code for the last consonant are different codes.
　検索部３１ｆは、文字変換部３１ｅにより変換されたハングル文字および未変換の字母の辞書検索コードについて、同じ位置に同じ辞書検索コードを含んだ言葉を辞書３０ｄから検索する。そして、検索部３１ｆは、検索の結果、辞書３０ｄから言葉が検索された場合、検索された言葉を表示制御部３１ｂへ出力する。表示制御部３１ｂは、検索部３１ｆにより検索された言葉を入力候補表示部２６に入力候補として表示させる。 The search unit 31f searches the dictionary 30d for a word including the same dictionary search code at the same position with respect to the dictionary search code of the Hangul character converted by the character conversion unit 31e and the unconverted character. Then, when a word is searched from the dictionary 30d as a result of the search, the search unit 31f outputs the searched word to the display control unit 31b. The display control unit 31b causes the input candidate display unit 26 to display the words searched by the search unit 31f as input candidates.
　次に、携帯端末２０によりハングル文字を入力する流れを説明する。図１３Ａ、１３Ｂには、省略を行わずにハングル文字の入力を行う場合の入力手順が示されている。なお、図１３Ａは、終音なしハングル文字を入力する場合を示す図である。図１３Ｂは、終音ありハングル文字を入力する場合を示す図である。図１３Ａ、１３Ｂでは、字母の指定を行った部分に網点のパターンを付している。図１３Ａの例では、子音入力モードで第１のタッチ操作を行って頭子音の標準入力を行う。携帯端末２０は、子音入力モードで標準入力が行われると、入力モードが母音入力モードに切り替わる。そして、図１３Ａの例では、第２のタッチ操作で母音の入力を行う。このように、頭子音を入力した際に、入力モードが母音入力モードに切り替わることにより、母音を効率良く入力できる。 Next, the flow of inputting Korean characters using the mobile terminal 20 will be described. 13A and 13B show an input procedure when inputting Korean characters without omission. FIG. 13A is a diagram illustrating a case where a Korean character without end sound is input. FIG. 13B is a diagram illustrating a case where a Hangul character with an end sound is input. In FIGS. 13A and 13B, a halftone dot pattern is attached to a portion for which a character is designated. In the example of FIG. 13A, the standard input of the head consonant is performed by performing the first touch operation in the consonant input mode. When the standard input is performed in the consonant input mode, the input mode is switched to the vowel input mode. In the example of FIG. 13A, a vowel is input by the second touch operation. Thus, when the head consonant is input, the input mode is switched to the vowel input mode, so that the vowel can be input efficiently.
　また、図１３Ｂの例では、子音入力モードで第１のタッチ操作を行って頭子音の標準入力を行う。携帯端末２０は、子音入力モードで標準入力が行われると、入力モードが母音入力モードに切り替わる。そして、図１３Ｂの例では、第２のタッチ操作で母音の入力を行う。携帯端末２０は、母音入力モードで母音の入力が行われると、入力モードが子音入力モードに切り替わる。そして、図１３Ｂの例では、第３のタッチ操作で末子音を指定した入力を行う。携帯端末２０は、末子音を指定した入力が行われると、入力された子音字母と母音字母と子音字母の組み合わせをハングル文字に変換する。また、携帯端末２０は、入力モードが子音入力モードのまま維持される。このように、頭子音を入力した際に、入力モードが母音入力モードに切り替わり、母音を入力した際に、入力モードが子音入力モードに切り替わることにより、ハングル文字を効率良く入力できる。 In the example of FIG. 13B, the standard input of the head consonant is performed by performing the first touch operation in the consonant input mode. When the standard input is performed in the consonant input mode, the input mode is switched to the vowel input mode. In the example of FIG. 13B, a vowel is input by the second touch operation. When the vowel input is performed in the vowel input mode, the portable terminal 20 switches the input mode to the consonant input mode. And in the example of FIG. 13B, the input which designated the last consonant by 3rd touch operation is performed. When an input designating the last consonant is performed, the portable terminal 20 converts the input consonant character, vowel character, and consonant character combination into Hangul characters. Moreover, the portable terminal 20 is maintained in the consonant input mode as the input mode. As described above, when a head consonant is input, the input mode is switched to the vowel input mode, and when the vowel is input, the input mode is switched to the consonant input mode, so that the Hangul characters can be input efficiently.
　一方、図１４Ａ～１４Ｆには、一部の字母の入力を省略してハングル文字の入力を行う場合の入力手順が示されている。なお、図１４Ａは、ハングル文字を２文字入力する際に１文字目と２文字目の頭子音のみを入力する場合を示す図である。図１４Ｂは、ハングル文字を２文字入力する際に１文字目の頭子音と２文字目の母音のみを入力する場合を示す図である。図１４Ｃは、ハングル文字を２文字入力する際に１文字目の頭子音と２文字目の末子音のみを入力する場合を示す図である。図１４Ｄは、ハングル文字を４文字入力する際に１文字目の頭子音と４文字目の頭子音のみを入力する場合を示す図である。図１４Ｅは、ハングル文字を４文字入力する際に１文字目の頭子音と４文字目の母音のみを入力する場合を示す図である。図１４Ｆは、ハングル文字を４文字入力する際に１文字目の頭子音と４文字目の末子音のみを入力する場合を示す図である。図１４Ａ～１４Ｆでは、字母の指定を行った部分に網点のパターンを付している。 On the other hand, FIGS. 14A to 14F show an input procedure for inputting Korean characters while omitting the input of some characters. FIG. 14A is a diagram illustrating a case where only the first consonant of the first character and the second character are input when inputting two Korean characters. FIG. 14B is a diagram illustrating a case where only the first consonant and the second vowel are input when inputting two Korean characters.

FIG. 14E is a diagram illustrating a case where only the first consonant and the fourth vowel are input when four Hangul characters are input. FIG. 14F is a diagram illustrating a case where only the first consonant and the last consonant of the fourth character are input when four Hangul characters are input. In FIGS. 14A to 14F, a halftone dot pattern is attached to a portion where a character is designated.
　図１４Ａの例では、子音入力モードで第１のタッチ操作を行って頭子音のみを指定した入力を行う。携帯端末２０は、頭子音のみを指定した入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ａの例では、第２のタッチ操作でも頭子音のみを指定した入力を行う。携帯端末２０は、辞書３０ｄから１文字目と２文字目の頭子音が指定された字母の言葉を検索し、検索された言葉を入力候補表示部２６に入力候補として表示させる。 In the example of FIG. 14A, the first touch operation is performed in the consonant input mode to input only the head consonant. When an input designating only a head consonant is performed, the input mode is maintained in the consonant input mode. In the example of FIG. 14A, an input specifying only a head consonant is performed even in the second touch operation. The mobile terminal 20 searches the dictionary 30d for the word of the character in which the first and second initial consonants are designated, and displays the searched word on the input candidate display unit 26 as an input candidate.
　また、図１４Ｂの例では、子音入力モードで第１のタッチ操作を行って頭子音のみを指定した入力を行う。携帯端末２０は、頭子音のみを指定した入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ｂの例では、第２のタッチ操作で「＊」を指定した入力を行う。携帯端末２０は、「＊」の入力が行われると、入力モードが母音入力モードに切り替わる。そして、図１４Ｂの例では、第３のタッチ操作で母音の入力を行う。携帯端末２０は、辞書３０ｄから１文字目の頭子音と２文字目の母音が指定された字母の言葉を検索し、検索された言葉を入力候補表示部２６に入力候補として表示させる。 Further, in the example of FIG. 14B, the first touch operation is performed in the consonant input mode, and the input specifying only the head consonant is performed. When an input designating only a head consonant is performed, the input mode is maintained in the consonant input mode. In the example of FIG. 14B, an input specifying “*” is performed by the second touch operation. When the input of “*” is performed, the mobile terminal 20 switches the input mode to the vowel input mode. And in the example of FIG. 14B, a vowel is input by 3rd touch operation. The portable terminal 20 searches the dictionary 30d for words of the first character specified by the first character consonant and the second character vowel, and causes the input candidate display unit 26 to display the searched words as input candidates.

When an input designating only a head consonant is performed, the input mode is maintained in the consonant input mode. In the example of FIG. 14C, an input specifying “#” is performed by the second touch operation. When “#” is input, the portable terminal 20 is maintained in the consonant input mode. In the example of FIG. 14C, the last consonant is input by the third touch operation. The portable terminal 20 searches the dictionary 30d for words of the first character in which the first character's first consonant and the second character's last consonant are designated, and displays the searched words as input candidates on the input candidate display unit 26.
　また、図１４Ｄの例では、子音入力モードで第１のタッチ操作を行って頭子音のみを指定した入力を行う。携帯端末２０は、頭子音のみを指定した入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ｄの例では、第２のタッチ操作で「＃＃」を指定した入力を行う。携帯端末２０は、「＃＃」の入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ｄの例では、第３のタッチ操作で頭子音のみの入力を行う。携帯端末２０は、辞書３０ｄから１文字目の頭子音と３文字目以降の頭子音が指定された字母の言葉を検索し、検索された言葉を入力候補表示部２６に入力候補として表示させる。 Further, in the example of FIG. 14D, the first touch operation is performed in the consonant input mode to perform input specifying only the head consonant. When an input designating only a head consonant is performed, the input mode is maintained in the consonant input mode. In the example of FIG. 14D, an input designating “##” is performed by the second touch operation. When the input of “##” is performed, the portable terminal 20 is maintained in the consonant input mode. In the example of FIG. 14D, only the head consonant is input by the third touch operation. The mobile terminal 20 searches the dictionary 30d for words of the first character specified by the first character consonant and the third and subsequent character consonants, and causes the input candidate display unit 26 to display the searched words as input candidates.
　また、図１４Ｅの例では、子音入力モードで第１のタッチ操作を行って頭子音のみを指定した入力を行う。携帯端末２０は、頭子音のみを指定した入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ｅの例では、第２のタッチ操作で「＊＊」を指定した入力を行う。携帯端末２０は、「＊＊」の入力が行われると、入力モードが母音入力モードに切り替わる。そして、図１４Ｅの例では、第３のタッチ操作で母音の入力を行う。携帯端末２０は、辞書３０ｄから１文字目の頭子音と３文字目以降の母音が指定された字母の言葉を検索し、検索された言葉を入力候補表示部２６に入力候補として表示させる。 Further, in the example of FIG. 14E, the first touch operation is performed in the consonant input mode to input only the head consonant. When an input designating only a head consonant is performed, the input mode is maintained in the consonant input mode. In the example of FIG. 14E, an input specifying “**” is performed by the second touch operation. When the input of “**” is performed, the mobile terminal 20 switches the input mode to the vowel input mode. And in the example of FIG. 14E, a vowel is input by 3rd touch operation. The mobile terminal 20 searches the dictionary 30d for words of the first character specified by the first consonant and the third and subsequent vowels, and displays the searched words on the input candidate display unit 26 as input candidates.
　また、図１４Ｆの例では、子音入力モードで第１のタッチ操作を行って頭子音のみを指定した入力を行う。携帯端末２０は、頭子音のみを指定した入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ｆの例では、第２のタッチ操作で「＃＃」を指定した入力を行う。携帯端末２０は、「＃＃」の入力が行われると、入力モードが子音入力モードのまま維持される。そして、図１４Ｆの例では、第３のタッチ操作で末子音の入力を行う。携帯端末２０は、辞書３０ｄから１文字目の頭子音と３文字目以降の末子音が指定された字母の言葉を検索し、検索された言葉を入力候補表示部２６に入力候補として表示させる。 Further, in the example of FIG. 14F, the first touch operation is performed in the consonant input mode to input only the head consonant. When an input designating only a head consonant is performed, the input mode is maintained in the consonant input mode. In the example of FIG. 14F, input specifying “##” is performed by the second touch operation. When the input of “##” is performed, the portable terminal 20 is maintained in the consonant input mode. In the example of FIG. 14F, the last consonant is input by the third touch operation. The mobile terminal 20 searches the dictionary 30d for words of the first character that specifies the first consonant and the third and subsequent consonants, and causes the input candidate display unit 26 to display the searched words as input candidates.
　利用者は、図１４Ａ～１４Ｆの何れの場合でも、入力候補表示部２６に表示された入力候補の選択することにより、全ての文字の字母を入力しなくてもハングル文字の入力を行うことができる。 In any of the cases shown in FIGS. 14A to 14F, the user can input Korean characters without inputting all the characters by selecting the input candidates displayed on the input candidate display unit 26. it can.
　次に、携帯端末２０によりハングル文字を入力する具体例を説明する。図１５～図１７を参照して、「韓国語」を表すハングル文字の入力する流れを示した図である。図１５～図１７のＰ０１～Ｐ８、Ｐ１１～Ｐ１３、Ｐ２１～Ｐ２３には、いずれも入力部２２が模式的に示されている。説明を簡単にするため、Ｐ０１～Ｐ２３のボタン２４上には数字表示をしている。実機上ではボタン２４上の数字表示は不要である。また、説明を簡単にするために、説明文中では、「韓国語」のハングル字母を以下のローマ字で表す。
　「韓」：　頭子音＝ｈ、母音＝ａ、末子音＝ｎ
　「国」：　頭子音＝ｋ、母音＝ｕ、末子音＝ｋ
　「語」：　頭子音＝－、母音＝ｅｏ、末子音＝なし Next, a specific example of inputting Korean characters using the mobile terminal 20 will be described. FIG. 18 is a diagram showing a flow of inputting Korean characters representing “Korean” with reference to FIGS. 15 to 17. The input unit 22 is schematically shown in P01 to P8, P11 to P13, and P21 to P23 of FIGS. In order to simplify the explanation, numbers are displayed on the buttons 24 of P01 to P23. On the actual machine, the numerical display on the button 24 is not necessary. In order to simplify the explanation, the Korean character of “Korean” is expressed in the following Roman letters in the explanation.
“Korean”: initial consonant = h, vowel = a, last consonant = n
“Country”: initial consonant = k, vowel = u, last consonant = k
"Word": Initial consonant =-, vowel = eo, end consonant = none
　図１５は、字母を省略せずに入力する流れを示した図である。Ｐ０１では、子音入力モードの状態において、「８」のボタン２４をタッチするとボタン２４を中心に選択領域２５が表示されて入力選択範囲が８方向に広がる。ここでは「８」のボタン２４に右向きにスライド操作を行って頭子音「ｈ」の入力をする。これは頭子音の標準入力であるため、入力直後に母音入力モードへの切替が行われ、各ボタン２４に母音が表示される。 FIG. 15 is a diagram showing a flow of inputting without omitting the letter. In P01, when the “8” button 24 is touched in the consonant input mode, the selection area 25 is displayed around the button 24 and the input selection range is expanded in eight directions. Here, the head consonant “h” is input by performing a slide operation to the right of the “8” button 24. Since this is a standard input of head consonant, switching to the vowel input mode is performed immediately after the input, and the vowel is displayed on each button 24.
　Ｐ０２では、母音入力モードの状態において、「１」のボタン２４をタッチするとボタン２４を中心に選択領域２５が表示されて入力選択範囲が左右方向に広がる。ここでは「１」のボタン２４をスライド操作せずに「ａ」の入力をする。これは母音入力であるため、入力直後に子音入力モードへの切替が行われ、各ボタン２４に子音が表示される。 In P02, when the “1” button 24 is touched in the state of the vowel input mode, the selection area 25 is displayed around the button 24 and the input selection range expands in the left-right direction. Here, “a” is input without sliding the “1” button 24. Since this is a vowel input, switching to the consonant input mode is performed immediately after the input, and the consonant is displayed on each button 24.
　Ｐ０３では、子音入力モードの状態において、「２」のボタン２４にタッチするとボタン２４を中心に選択領域２５が表示されて入力選択範囲が８方向に広がる。ここでは「２」のボタン２４に下向きにスライド操作を行って末子音「ｎ」の入力をする。これは末子音の入力であるため、入力後に入力モードの切替は行われず、各ボタン２４の表示は子音のままである。 In P03, when the “2” button 24 is touched in the consonant input mode, the selection area 25 is displayed around the button 24 and the input selection range is expanded in eight directions. Here, a slide operation is performed downward on the button 24 of “2” to input the last consonant “n”. Since this is an input of the last consonant, the input mode is not switched after the input, and the display of each button 24 remains a consonant.
　Ｐ０４では、子音入力モードの状態において、「１」のボタン２４をタッチするとボタン２４を中心に選択領域２５が表示されて入力選択範囲が８方向に広がる。ここでは「１」のボタン２４をスライド操作せずに頭子音「ｋ」の入力をする。これは頭子音の標準入力であるため、入力直後に母音入力モードへの切替が行われ、各ボタン２４に母音が表示される。 In P04, when the “1” button 24 is touched in the consonant input mode, the selection area 25 is displayed around the button 24 and the input selection range is expanded in eight directions. Here, the head consonant “k” is input without sliding the “1” button 24. Since this is a standard input of head consonant, switching to the vowel input mode is performed immediately after the input, and the vowel is displayed on each button 24.
　Ｐ０５では、母音入力モードの状態において、「４」のボタン２４をタッチするとボタン２４を中心に選択領域２５が表示されて入力選択範囲が左右方向に広がる。ここでは「４」のボタン２４をスライド操作せずに「ｕ」の入力をする。これは母音入力であるため、入力直後に子音入力モードへの切替が行われ、各ボタン２４に子音が表示される。 In P05, when the “24” button 24 is touched in the state of the vowel input mode, the selection area 25 is displayed around the button 24 and the input selection range expands in the left-right direction. Here, “u” is input without sliding the “4” button 24. Since this is a vowel input, switching to the consonant input mode is performed immediately after the input, and the consonant is displayed on each button 24.
　Ｐ０６では、子音入力モードの状態において、「１」のボタン２４をタッチするとボタン２４を中心に選択領域２５が表示されて入力選択範囲が８方向に広がる。ここでは「１」のボタン２４に下向きにスライド操作を行って末子音「ｋ」の入力をする。これは末子音の入力であるため、入力後に入力モードの切替は行われず、各ボタン２４の表示は子音のままである。 In P06, when the “1” button 24 is touched in the consonant input mode, the selection area 25 is displayed around the button 24 and the input selection range is expanded in eight directions. Here, a slide operation is performed downward on the button 24 of “1” to input the last consonant “k”. Since this is an input of the last consonant, the input mode is not switched after the input, and the display of each button 24 remains a consonant.
　Ｐ０７では、子音入力モードの状態において、「８」のボタン２４をスライド操作せずに頭子音「－」の入力をする。これは頭子音の標準入力であるため、入力直後に母音入力モードへの切替が行われ、各ボタン２４に母音が表示される。 In P07, in the consonant input mode, the head consonant “-” is input without sliding the “8” button 24. Since this is a standard input of head consonant, switching to the vowel input mode is performed immediately after the input, and the vowel is displayed on each button 24.
　Ｐ０８では、母音入力モードの状態において、「２」のボタン２４をスライド操作せずに「ｅｏ」の入力をする。これは母音入力であるため、入力直後に子音入力モードへの切替が行われ、各ボタン２４に子音が表示される。 In P08, “eo” is input without sliding the “2” button 24 in the vowel input mode. Since this is a vowel input, switching to the consonant input mode is performed immediately after the input, and the consonant is displayed on each button 24.
　以上のように、「韓国語」を表すハングル文字を省略せずに入力する場合、Ｐ０１～Ｐ０８の８回のタッチ操作で入力できる。 As described above, if you enter the Korean characters representing “Korean” without omitting them, you can enter them with eight touch operations from P01 to P08.
　図１６は、字母を省略して入力する流れを示した図である。省略の方法としては、各ハングル文字の頭子音のみを入力する例を示す。 FIG. 16 is a diagram showing a flow of input with the letter omitted. As an omission method, an example in which only the initial consonant of each Hangul character is input is shown.
　Ｐ１１～Ｐ１３はすべて子音入力モードの状態で入力し、頭子音のみの入力であるため、入力後の入力モード切替えはなく、子音入力モードが保持される。 P11 to P13 are all input in the state of consonant input mode and are input of only the head consonant. Therefore, there is no input mode switching after input, and the consonant input mode is maintained.
　Ｐ１１では、「８」のボタン２４に右上向きのスライド操作を行って頭子音「ｈ」のみの入力をする。Ｐ１２では、「１」のボタン２４に上向きのスライド操作を行って頭子音「ｋ」のみの入力をする。Ｐ１３では、「８」のボタン２４に上向きのスライド操作を行って頭子音「－」のみの入力をする。 In P11, the slide operation of the upper right direction is performed on the button 24 of “8”, and only the initial consonant “h” is input. In P12, an upward slide operation is performed on the button 24 of “1”, and only the head consonant “k” is input. In P13, an upward slide operation is performed on the button 24 of “8”, and only the head consonant “−” is input.
　以上のように、「韓国語」を表すハングル文字の頭文字のみを入力する場合、Ｐ１１～Ｐ１３の３回のタッチ操作で入力でき、同じ頭文字を持つ単語が入力候補表示部２６に表示され、その中から「韓国語」を表す単語を選択することができる。 As described above, when inputting only the initials of Hangul characters representing “Korean”, the input can be performed by three touch operations from P11 to P13, and the words having the same initials are displayed on the input candidate display unit 26. A word representing “Korean” can be selected from the list.
　図１７は、字母を省略して入力する流れを示した図である。省略の方法としては、１文字目の頭子音と単語の最終文字（この場合は３文字目）の母音のみを入力する例を示す。 FIG. 17 is a diagram showing a flow of input with the letter omitted. As an omission method, an example in which only the first consonant of the first character and the vowel of the last character of the word (in this case, the third character) are input is shown.
　Ｐ２１では、子音入力モードの状態において、「８」のボタン２４に右上向きのスライド操作を行って頭子音「ｈ」のみの入力をする。これは頭子音のみの入力であるため、入力直後に入力モードの切替はなく、各ボタン２４の表示が子音のままである。 In P21, in the state of the consonant input mode, a slide operation of the upper right direction is performed on the button 24 of “8” to input only the head consonant “h”. Since this is an input of only a head consonant, the input mode is not switched immediately after the input, and the display of each button 24 remains a consonant.
　Ｐ２２では、子音入力モードの状態において、「２」のボタン２４に左向きのスライド操作を行って複数文字分の頭子音の入力を省略することを意味する記号「＊＊」の入力をする。これは左右並行のスライド操作で頭子音の標準入力に属すため、入力直後に母音入力モードへの切替が行われ、各ボタン２４に母音が表示される。 In P22, in the state of the consonant input mode, the symbol “**”, which means that the input of a plurality of characters of the consonant is omitted by performing a leftward slide operation on the “2” button 24, is input. Since this belongs to the standard input of the head consonant by the left and right parallel slide operation, the vowel input mode is switched immediately after the input, and the vowel is displayed on each button 24.
　Ｐ２３では、母音入力モードの状態において、「２」のボタン２４をスライド操作せずに「ｅｏ」の入力をする。これは母音入力であるため、入力直後に子音入力モードへの切替が行われ、各ボタン２４に子音が表示される。 In P23, in the state of the vowel input mode, “eo” is input without sliding the “2” button 24. Since this is a vowel input, switching to the consonant input mode is performed immediately after the input, and the consonant is displayed on each button 24.
　以上のように、「韓国語」を表すハングル文字の１文字目の頭子音と単語の最終文字の母音のみを入力する場合、Ｐ２１～Ｐ２３の３回のタッチ操作で入力でき、同じ字母を持つ単語が入力候補表示部２６に表示され、その中から「韓国語」を表す単語を選択することができる。 As described above, when only the first consonant of the Hangul character representing “Korean” and the vowel of the last character of the word are input, they can be input by three touch operations from P21 to P23 and have the same character. A word is displayed on the input candidate display unit 26, and a word representing "Korean" can be selected from the word candidate display unit 26.
　次に、本実施例に係る携帯端末２０でハングル文字の入力を行う際の処理の流れを説明する。図１８は、ハングル文字入力処理の手順を示すフローチャートである。このハングル文字入力処理は、ハングル文字の入力開始が指定された場合に実行される。 Next, the flow of processing when inputting Korean characters on the mobile terminal 20 according to the present embodiment will be described. FIG. 18 is a flowchart showing the procedure of the Korean character input process. This Korean character input process is executed when the start of inputting Korean characters is designated.
　図１８に示すように、切替制御部３１ｃは、初期の動作モードとして子音入力モードへの切り替えを指示し、動作モードを子音入力モードに設定する（ステップＳ１）。表示制御部３１ｂは、動作モードを設定に子音入力モードされると、入力部２２の各ボタン２４に子音を表す字母を表示した子音入力画面をタッチパネル２１に表示させる（ステップＳ２）。操作判別部３１ａは、検出部１２による検出結果に基づき、入力部２２の何れかのボタン２４にタッチ操作が行われたか判定する（ステップＳ３）。操作判別部３１ａは、タッチ操作が検出されない場合（ステップＳ３否定）、処理終了が指示されたか否かを判定する（ステップＳ１６）。操作判別部３１ａは、処理終了が指示された場合（ステップＳ１６肯定）、処理を終了する。一方、操作判別部３１ａは、処理終了が指示されていない場合（ステップＳ１６否定）、ステップ３へ移行する。タッチ操作が検出された場合（ステップＳ３肯定）、文字種判別部３１ｄは、タッチ操作による入力がハングル文字に関連するものであるかを判別する（ステップＳ４）。ここでいうハングル文字記号に関連するものとは、ハングル文字記号自身以外に、前述した「＊」、「＊＊」、「＃」、「＃＃」のような、文字変換部３１ｅに渡す辞書検索コードを有する記号を指す。入力がハングル文字に関連するものでない場合（ステップＳ４否定）、入力されたボタン２４に応じた処理を行ない（ステップＳ５）その後、ステップＳ３へ移行する。入力がハングル文字に関連するものである場合（ステップＳ４肯定）、切替制御部３１ｃは、現在の動作モードが子音入力モードであるか否か判定する（ステップＳ６）。現在の動作モードが子音入力モードである場合（ステップＳ６肯定）、切替制御部３１ｃは、指定された入力が標準入力または頭子音任意母音入力であるか否かを判定する（ステップＳ７）。指定された入力が標準入力または頭子音任意母音入力である場合（ステップＳ７肯定）、切替制御部３１ｃは、子音入力モードへの切り替えを指示する（ステップＳ８）。表示制御部３１ｂは、子音入力モードへの切り替えが指示されると、入力部２２の各ボタン２４に子音を表す字母を表示した子音入力画面をタッチパネル２１に表示させ（ステップＳ９）、後述するステップＳ１２へ移行する。また、指定された入力が標準入力または頭子音任意母音入力でない場合（ステップＳ７否定）後述するステップＳ１２へ移行する。 As shown in FIG. 18, the switching control unit 31c instructs switching to the consonant input mode as an initial operation mode, and sets the operation mode to the consonant input mode (step S1). When the operation mode is set and the consonant input mode is set, the display control unit 31b causes the touch panel 21 to display a consonant input screen displaying characters representing consonants on the buttons 24 of the input unit 22 (step S2). The operation determination unit 31a determines whether a touch operation has been performed on any button 24 of the input unit 22 based on the detection result of the detection unit 12 (step S3). When the touch operation is not detected (No at Step S3), the operation determining unit 31a determines whether or not an instruction to end the process is given (Step S16). The operation determination part 31a complete | finishes a process, when the process completion is instruct | indicated (step S16 affirmation). On the other hand, the operation determination unit 31a proceeds to Step 3 when the process end is not instructed (No at Step S16). When the touch operation is detected (Yes at Step S3), the character type determination unit 31d determines whether the input by the touch operation is related to the Hangul character (Step S4). What is related to the Hangul character symbol here is a dictionary that is passed to the character conversion unit 31e, such as “*”, “**”, “#”, “##” described above, in addition to the Hangul character symbol itself. Refers to a symbol having a search code. If the input is not related to the Hangul character (No at Step S4), the process corresponding to the input button 24 is performed (Step S5), and then the process proceeds to Step S3. When the input is related to the Hangul character (Yes at Step S4), the switching control unit 31c determines whether or not the current operation mode is the consonant input mode (Step S6). When the current operation mode is the consonant input mode (Yes at Step S6), the switching control unit 31c determines whether the designated input is a standard input or a head consonant arbitrary vowel input (Step S7). When the designated input is a standard input or a head consonant arbitrary vowel input (Yes at Step S7), the switching control unit 31c instructs to switch to the consonant input mode (Step S8). When instructed to switch to the consonant input mode, the display control unit 31b causes the touch panel 21 to display a consonant input screen on which letters representing consonants are displayed on the buttons 24 of the input unit 22 (step S9). The process proceeds to S12. If the designated input is not the standard input or the initial consonant arbitrary vowel input (No at Step S7), the process proceeds to Step S12 described later.
　一方、現在の動作モードが子音入力モードでない場合（ステップＳ６否定）、切替制御部３１ｃは、現在が母音入力モードであるため、次に子音を入力させるために、子音入力モードへの切り替えを指示する（ステップＳ１０）。表示制御部３１ｂは、子音入力モードへの切り替えが指示されると、入力部２２の各ボタン２４に子音を表す字母を表示した子音入力画面をタッチパネル２１に表示させ（ステップＳ１１）、後述するステップＳ１２へ移行する。 On the other hand, when the current operation mode is not the consonant input mode (No at Step S6), the switching control unit 31c instructs the switch to the consonant input mode in order to input the consonant next because the current is the vowel input mode. (Step S10). When instructed to switch to the consonant input mode, the display control unit 31b causes the touch panel 21 to display a consonant input screen on which letters representing consonants are displayed on the buttons 24 of the input unit 22 (step S11). The process proceeds to S12.
　ステップＳ１２では、後述する文字記号判別処理を行って入力された字母、および字母の辞書検索コードを判別する。文字変換部３１ｅは、特定された字母がハングル文字に変換できる場合はハングル文字に変換する（ステップＳ１３）。表示制御部３１ｂは、文字変換部３１ｅによる変換結果をタッチパネル２１に表示させる（ステップＳ１４）。検索部３１ｆは、入力された位置に入力された字母を含んだ言葉を辞書３０ｄから検索し（ステップＳ１５）、検索終了後、ステップＳ３へ移行する。検索部３１ｆにより検索された言葉は入力候補表示部２６に入力候補として表示される。 In step S12, a character / symbol discrimination process described later is performed to determine the input character and the dictionary search code of the character. The character conversion unit 31e converts the identified alphabet into a Hangul character if it can be converted into a Hangul character (step S13). The display control unit 31b displays the conversion result by the character conversion unit 31e on the touch panel 21 (step S14). The search unit 31f searches the dictionary 30d for a word including the input letter at the input position (step S15), and after the search ends, proceeds to step S3. The words searched by the search unit 31 f are displayed as input candidates on the input candidate display unit 26.
　図１９は、文字記号判別処理の手順を示すフローチャートである。この文字記号判別処は、ハングル文字入力処理のステップＳ１２から実行される。 FIG. 19 is a flowchart showing the procedure of character / symbol discrimination processing. This character symbol discrimination processing is executed from step S12 of the Korean character input processing.
　図１９に示すように、文字種判別部３１ｄは、現在の動作モードが子音入力モードか、または母音入力モードかを判定する（ステップＳ２０）。文字種判別部３１ｄは、動作モードが子音入力モードの場合、ステップＳ２１へ移行し、タッチ操作において上下のスライドがあったか否かを判定する（ステップＳ２１）。文字種判別部３１ｄは、タッチ操作において上方向へのスライドがあった場合、左右のスライドがあったか否かを判定する（ステップＳ２２）。文字種判別部３１ｄは、タッチ操作において左方向へのスライドがあった場合、入力文字記号記憶テーブルＣＵＬを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ２３）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作においてスライドがない場合、入力文字記号記憶テーブルＣＵＮを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ２４）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作において右方向にスライドがあった場合、入力文字記号記憶テーブルＣＵＲを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ２５）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。 As shown in FIG. 19, the character type determination unit 31d determines whether the current operation mode is a consonant input mode or a vowel input mode (step S20). When the operation mode is the consonant input mode, the character type determination unit 31d proceeds to step S21 and determines whether or not there has been a vertical slide in the touch operation (step S21). When there is a slide upward in the touch operation, the character type determination unit 31d determines whether there is a left / right slide (step S22). When there is a leftward slide in the touch operation, the character type determination unit 31d reads the letter and dictionary search code corresponding to the touched button 24 with reference to the input character symbol storage table CUL (step S23). The input character and dictionary search code are specified (step S44). In addition, when there is no slide in the touch operation, the character type determination unit 31d reads the letter and the dictionary search code corresponding to the button 24 operated by referring to the input character symbol storage table CUN (step S24) and input A character and a dictionary search code are specified (step S44). In addition, when there is a slide in the right direction in the touch operation, the character type determination unit 31d reads the letter and dictionary search code corresponding to the button 24 touched by referring to the input character symbol storage table CUR (step S25). The entered letter and dictionary search code are specified (step S44).
　一方、文字種判別部３１ｄは、タッチ操作において上下へのスライドがない場合、左右のスライドがあったか否かを判定する（ステップＳ２６）。文字種判別部３１ｄは、タッチ操作において左方向へのスライドがあった場合、入力文字記号記憶テーブルＣＮＬを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ２７）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作においてスライドがない場合、入力文字記号記憶テーブルＣＮＮを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ２８）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作において右方向にスライドがあった場合、入力文字記号記憶テーブルＣＮＲを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ２９）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。 On the other hand, if there is no up / down slide in the touch operation, the character type determination unit 31d determines whether there is a left / right slide (step S26). When there is a leftward slide in the touch operation, the character type determination unit 31d reads the letter and dictionary search code corresponding to the touched button 24 with reference to the input character symbol storage table CNL (step S27). The input character and dictionary search code are specified (step S44). In addition, when there is no slide in the touch operation, the character type determination unit 31d reads the letter and the dictionary search code corresponding to the button 24 touched with reference to the input character symbol storage table CNN (step S28). A character and a dictionary search code are specified (step S44). In addition, when there is a slide in the right direction in the touch operation, the character type determination unit 31d reads the alphabet and the dictionary search code corresponding to the button 24 touched by referring to the input character symbol storage table CNR (step S29). The entered letter and dictionary search code are specified (step S44).
　一方、文字種判別部３１ｄは、タッチ操作において下方向へのスライドがあった場合、左右のスライドがあったか否かを判定する（ステップＳ３０）。文字種判別部３１ｄは、タッチ操作において左方向へのスライドがあった場合、入力文字記号記憶テーブルＣＤＬを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ３１）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作においてスライドがない場合、入力文字記号記憶テーブルＣＤＮを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ３２）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作において右方向にスライドがあった場合、入力文字記号記憶テーブルＣＤＲを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ３３）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。 On the other hand, when there is a downward slide in the touch operation, the character type determination unit 31d determines whether there is a left / right slide (step S30). When there is a leftward slide in the touch operation, the character type determination unit 31d reads the letter and dictionary search code corresponding to the touched button 24 with reference to the input character symbol storage table CDL (step S31). The input character and dictionary search code are specified (step S44). In addition, when there is no slide in the touch operation, the character type determination unit 31d reads the letter and dictionary search code corresponding to the button 24 operated by referring to the input character symbol storage table CDN (step S32) and input. A character and a dictionary search code are specified (step S44). In addition, when the touch operation has been slid in the right direction, the character type determination unit 31d reads the alphabet and dictionary search code corresponding to the button 24 that has been touched with reference to the input character symbol storage table CDR (step S33). The entered letter and dictionary search code are specified (step S44).
　一方、動作モードが母音入力モードの場合、文字種判別部３１ｄは、左右のスライドがあったか否かを判定する（ステップＳ４０）。文字種判別部３１ｄは、タッチ操作において左方向へのスライドがあった場合、入力文字記号記憶テーブルＶＮＬを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ４１）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作においてスライドがない場合、入力文字記号記憶テーブルＶＮＮを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ４２）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。また、文字種判別部３１ｄは、タッチ操作において右方向にスライドがあった場合、入力文字記号記憶テーブルＶＮＲを参照してタッチ操作されたボタン２４に対応する字母および辞書検索コードを読み出し（ステップＳ４３）、入力された字母および辞書検索コードを特定する（ステップＳ４４）。 On the other hand, when the operation mode is the vowel input mode, the character type determination unit 31d determines whether or not there is a left / right slide (step S40). When there is a leftward slide in the touch operation, the character type determination unit 31d reads the letter and the dictionary search code corresponding to the touched button 24 with reference to the input character symbol storage table VNL (step S41). The input character and dictionary search code are specified (step S44). In addition, when there is no slide in the touch operation, the character type determination unit 31d reads the letter and the dictionary search code corresponding to the button 24 that has been touched with reference to the input character symbol storage table VNN (step S42). A character and a dictionary search code are specified (step S44). In addition, when there is a slide in the right direction in the touch operation, the character type determination unit 31d reads the letter and dictionary search code corresponding to the button 24 touched by referring to the input character symbol storage table VNR (step S43). The entered letter and dictionary search code are specified (step S44).
　上述してきたように、本実施例に係る携帯端末２０は、タッチパネル２１の表示領域に対する操作を検出する。また、本実施例に係る携帯端末２０は、ハングル文字の入力を行う際に、子音入力画面、および母音入力画面の何れかをタッチパネル２１に表示させる制御を行う。子音入力画面は、タッチパネル２１の表示領域を区分した各ボタン２４にハングル文字の子音を表す字母をそれぞれ表示し、ボタン２４に対するスライド操作の有無、スライド方向の違いの何れかにより頭子音または末子音を指定した入力を受け付ける。母音入力画面は、各ボタン２４にハングル文字の母音を表す字母をそれぞれ表示し、母音を表す字母の入力を受け付ける。そして、本実施例に係る携帯端末２０は、子音入力画面の何れかのボタン２４に対して頭子音を指定する操作を検出した場合、タッチパネル２１に表示される画面を母音入力画面に切り替える。これにより、母音を入力するためにモードを切り替える操作が不要となるため、ハングル文字を効率良く入力でき、ハングル文字の入力における操作回数を抑制できる。 As described above, the mobile terminal 20 according to the present embodiment detects an operation on the display area of the touch panel 21. Moreover, the portable terminal 20 which concerns on a present Example performs control which displays either a consonant input screen and a vowel input screen on the touch panel 21, when inputting a Korean character. The consonant input screen displays a letter representing a consonant of a Hangul character on each button 24 that divides the display area of the touch panel 21, and a head consonant or a final consonant depending on whether a slide operation is performed on the button 24 or a difference in slide direction. Accepts input specifying. The vowel input screen displays a letter representing the vowel of the Hangul character on each button 24 and accepts an input of the letter representing the vowel. And the portable terminal 20 which concerns on a present Example switches the screen displayed on the touch panel 21 to a vowel input screen, when operation which designates a head consonant with respect to any button 24 of a consonant input screen is detected. This eliminates the need to switch modes to input vowels, so that Korean characters can be input efficiently and the number of operations in inputting Korean characters can be suppressed.
　ここで、ハングル文字は、子音を表す字母が頭子音の字母なのか末子音の字母なのかを字母のみから判別できない。このため、例えば、単純に子音の字母が入力された段階で、子音字母＋母音字母＋子音字母の組み合わせをハングル文字に変換を行うものとする。この場合、後続する字母が母音を表す字母であれば、一旦、子音字母＋母音字母＋子音字母の組み合わせでハングル文字に変換した末子音の字母を次ハングル文字の頭子音の字母として訂正処理を行うことなる。この訂正処理は、利用者から見れば、入力したいハングル文字が一旦誤処理されるため、ユーザインターフェース上の欠陥があると言える。 Here, the Hangul character cannot determine whether the character representing the consonant is the first consonant or the last consonant. For this reason, for example, when a consonant character is simply input, the combination of consonant character + vowel character + consonant character is converted into a Hangul character. In this case, if the subsequent letter is a letter representing a vowel, the correct consonant letter + vowel letter + consonant letter combination is converted to the Hangul character as the final consonant letter of the next Hangul letter. Will do. From the user's point of view, this correction process can be said to have a defect on the user interface because a Korean character to be input is erroneously processed once.
　一方、本実施例に係る携帯端末２０は、子音の指定の際にスライド操作で標準入力や頭子音のみ入力、末子音入力が指定されることで、頭子音または末子音を指定した入力が行われるため、誤変換の発生を抑制できる。 On the other hand, in the portable terminal 20 according to the present embodiment, when a consonant is specified, a standard input or only a head consonant is input by a slide operation, and an end consonant input is specified. Therefore, occurrence of erroneous conversion can be suppressed.
　また、本実施例に係る携帯端末２０は、ボタン２４に対するスライド操作の有無、スライド方向の違いの何れかにより、頭子音の指定後に組み合わせる母音を指定する標準入力、頭子音を任意として母音を指定する頭子音任意母音入力をさらに受け付ける。そして、本実施例に係る携帯端末２０は、標準入力および頭子音任意母音入力を指定する操作を検出した場合、タッチパネル２１に表示される画面を母音入力画面に切り替える。また、本実施例に係る携帯端末２０は、ボタン２４に対するスライド操作の有無、スライド方向の違いの何れかにより、頭子音のみ指定する頭子音のみ入力、頭子音を任意として次の子音の指定する頭子音省略入力をさらに受け付ける。そして、本実施例に係る携帯端末２０は、頭子音のみ入力および頭子音省略入力を指定する操作を検出した場合、タッチパネル２１に表示される画面を子音入力画面に維持する。これにより、次に母音を入力する場合、母音入力画面が表示され、次に子音を入力する場合、子音入力画面が表示されるため、
字母の入力が行ないやすくなる。 In addition, the mobile terminal 20 according to the present embodiment designates a vowel as a standard input for specifying a vowel to be combined after a head consonant is specified, depending on any of the presence / absence of a slide operation on the button 24 and a difference in the slide direction. To accept an initial vowel input. And the portable terminal 20 which concerns on a present Example switches the screen displayed on the touch panel 21 to a vowel input screen, when operation which designates standard input and a head consonant arbitrary vowel input is detected. In addition, the portable terminal 20 according to the present embodiment inputs only a head consonant that designates only a head consonant, and designates the next consonant as an arbitrary head consonant, depending on whether or not the button 24 is slid and whether the sliding direction is different. Further accepts initial consonant omission input. And the portable terminal 20 which concerns on a present Example maintains the screen displayed on the touch panel 21 in a consonant input screen, when operation which designates only a head consonant input and a head consonant omission input is detected. As a result, the next time you input a vowel, the vowel input screen will be displayed, and the next time you input the consonant, the consonant input screen will be displayed.
It becomes easier to input characters.
　また、本実施例に係る携帯端末２０は、ハングルの複数の言葉を辞書として記憶する。また、本実施例に係る携帯端末２０は、子音入力画面および母音入力画面で指定された位置に指定された字母を含んだ言葉を辞書から検索する。そして、本実施例に係る携帯端末２０は、検索された言葉を入力候補としてタッチパネル２１に表示させる。これにより、言葉を全て指定しなくても、指定された位置に指定された字母を含んだ言葉が入力候補として表示されるため、文字の入力が行ないやすくなる。 Also, the mobile terminal 20 according to the present embodiment stores a plurality of Korean words as a dictionary. Moreover, the portable terminal 20 according to the present embodiment searches the dictionary for words including the designated letter at the position designated on the consonant input screen and the vowel input screen. And the portable terminal 20 which concerns on a present Example displays the searched word on the touch panel 21 as an input candidate. Thus, even if not all words are designated, words including the designated letter at the designated position are displayed as input candidates, so that it is easy to input characters.
　また、本実施例に係る携帯端末２０は、子音入力画面の各ボタン２４に平音字母を表示する。そして、本実施例に係る携帯端末２０は、平音字母を表示した何れか区分領域が指定された場合、当該平音字母に対応する濃音字母、激音字母を当該平音字母に隣接する区分領域に並べて表示する。また、本実施例に係る携帯端末２０は、母音入力画面の各ボタン２４に半母音なしの字母を表示する。そして、本実施例に係る携帯端末２０は、半母音なしの字母を表示した何れか区分領域が指定された場合、当該半母音なしの字母に対応する半母音ｙ付きの字母、半母音ｗ付きの字母を当該半母音なしの字母に隣接する区分領域に並べて表示する。これにより、子音入力画面および母音入力画面を１０個のボタン２４で構成できるため、１０個のボタン２４でハングル文字の入力を実現できる。 In addition, the mobile terminal 20 according to the present embodiment displays a flat character on each button 24 of the consonant input screen. Then, in the mobile terminal 20 according to the present embodiment, when any of the divided areas displaying the diacritic character is specified, the strong diacritical character and the intense diacritic character corresponding to the diabolic character are adjacent to the diacritical character. Display side-by-side in the segmented area. In addition, the mobile terminal 20 according to the present embodiment displays a letter without a semi-vowel on each button 24 of the vowel input screen. Then, in the mobile terminal 20 according to the present embodiment, when any divided region that displays a character without a semi-vowel is specified, the character with a semi-vowel y corresponding to the character without the semi-vowel, the character with a semi-vowel w Displayed side-by-side in a segmented area adjacent to a semi-vowelless character. Thereby, since the consonant input screen and the vowel input screen can be configured by the ten buttons 24, the input of Korean characters can be realized by the ten buttons 24.
　本実施例に係る携帯端末２０は、利用者が１０個のボタン２４を用いて、省略入力をしない標準入力で、常用単語の５１．８％のハングル文字が２回のタッチ、３８．９％のハングル文字が３回のタッチ、９．３％のハングル文字が４回のタッチで入力できる。このように少ないタッチ回数でハングル文字を入力できるため、入力効率を向上させることができる。また、本実施例に係る携帯端末２０は、字母の省略入力も提供しているため、常用単語等を入力するためのタッチ回数をさらに減らすことができる。 The mobile terminal 20 according to the present embodiment is a standard input in which the user uses ten buttons 24 and does not omit input, and 51.8% of Korean words in common words are touched twice, 38.9% Can be input with 3 touches and 9.3% Hangul characters with 4 touches. Since the Korean character can be input with such a small number of touches, the input efficiency can be improved. In addition, since the mobile terminal 20 according to the present embodiment also provides an input for omitting a character, the number of touches for inputting a common word or the like can be further reduced.
　さて、これまで開示の装置に関する実施例について説明したが、開示の技術は上述した実施例以外にも、種々の異なる形態にて実施されてよいものである。そこで、以下では、本発明に含まれる他の実施例を説明する。 Now, although the embodiments related to the disclosed apparatus have been described so far, the disclosed technology may be implemented in various different forms other than the above-described embodiments. Therefore, another embodiment included in the present invention will be described below.
　例えば、上記の実施例では、入力文字記号記憶テーブル３０ｃを入力文字記号記憶テーブルＣＵＬ、ＣＵＮ、ＣＵＲ、ＣＮＬ、ＣＮＮ、ＣＮＲ、ＣＤＬ、ＣＤＮ、ＣＤＲと９つに分けた場合について説明したが、開示の装置はこれに限定されない。例えば、処理対象とするスライド操作の有無、スライド方向のフィールドを設けて１つのテーブルをして構成してもよい。 For example, in the above embodiment, the case where the input character symbol storage table 30c is divided into nine as the input character symbol storage table CUL, CUN, CUR, CNL, CNN, CNR, CDL, CDN, CDR has been described. However, the apparatus is not limited to this. For example, a single table may be configured by providing the presence / absence of a slide operation to be processed and a field for the slide direction.
　また、上記の実施例では、子音を表す各字母を平音字母、濃音字母、激音字母に分類し、母音を表す各字母を半母音なし字母、半母音ｙ付き字母、半母音ｗ付き字母に分類した場合について説明したが、母音の分類方式はこれに限定されない。 Further, in the above embodiment, each letter representing a consonant is classified into a flat letter letter, a deep letter letter, and an intense letter letter, and each letter representing a vowel letter is classified into a letter without a half vowel, a letter with a half vowel y, and a letter with a half vowel w. However, the vowel classification method is not limited to this.
　また、各種の負荷や使用状況などに応じて、実施例２において説明した各処理の各ステップでの処理を任意に細かくわけたり、あるいはまとめたりすることができる。また、ステップを省略することもできる。 Also, the processing at each step of each processing described in the second embodiment can be arbitrarily finely divided or combined according to various loads and usage conditions. Also, the steps can be omitted.
　また、図示した各装置の各構成要素は機能概念的なものであり、必ずしも物理的に図示の如く構成されていることを要しない。すなわち、各装置の分散・統合の具体的状態は図示のものに限られず、その全部または一部を、各種の負荷や使用状況などに応じて、任意の単位で機能的または物理的に分散・統合して構成することができる。例えば、図１に示す表示制御部１３と、切替制御部１４とが統合されてもよい。また、図４に示す、操作判別部３１ａと、表示制御部３１ｂと切替制御部３１ｃや、文字種判別部３１ｄと文字変換部３１ｅとなどが統合されてもよい。 Also, each component of each illustrated apparatus is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific state of distribution / integration of each device is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, the display control unit 13 and the switching control unit 14 illustrated in FIG. 1 may be integrated. Moreover, the operation determination part 31a, the display control part 31b, the switching control part 31c, the character type determination part 31d, the character conversion part 31e, etc. which are shown in FIG. 4 may be integrated.
［ハングル文字入力プログラム］
　また、上記の実施例で説明したハングル文字入力装置の各種の処理は、あらかじめ用意されたプログラムをパーソナルコンピュータやワークステーションなどのコンピュータシステムで実行することによって実現することもできる。そこで、以下では、図２０を用いて、上記の実施例で説明したハングル文字入力装置と同様の機能を有するハングル文字入力プログラムを実行するコンピュータの一例を説明する。図２０は、ハングル文字入力プログラムを実行するコンピュータを示す図である。 [Hangul character input program]
The various processes of the Hangul character input device described in the above embodiment can also be realized by executing a program prepared in advance on a computer system such as a personal computer or a workstation. In the following, an example of a computer that executes a Hangul character input program having the same function as the Hangul character input device described in the above embodiment will be described with reference to FIG. FIG. 20 is a diagram illustrating a computer that executes a Korean character input program.
　図２０に示すように、コンピュータ３００は、ＣＰＵ（Central　Processing　Unit）３１０、ＲＯＭ（Read　Only　Memory）３２０、ＨＤＤ（Hard　Disk　Drive）３３０、ＲＡＭ（Random　Access　Memory）３４０を有する。これら３００～３４０の各部は、バス４００を介して接続される。 As shown in FIG. 20, the computer 300 includes a CPU (Central Processing Unit) 310, a ROM (Read Only Memory) 320, an HDD (Hard Disk Drive) 330, and a RAM (Random Access Memory) 340. These units 300 to 340 are connected via a bus 400.
　ＲＯＭ３２０には、上記の実施例１に示す表示制御部１３と、切替制御部１４と同様の機能、または上記の実施例２に示す表示制御部３１ｂと、切替制御部３１ｃと同様の機能を発揮するハングル文字入力プログラム３２０ａが予め記憶される。なお、ハングル文字入力プログラム３２０ａについては、適宜分離しても良い。 The ROM 320 exhibits the same functions as the display control unit 13 and the switching control unit 14 shown in the first embodiment, or the same functions as the display control unit 31b and the switching control unit 31c shown in the second embodiment. The Korean character input program 320a to be stored is stored in advance. The Korean character input program 320a may be separated as appropriate.
　そして、ＣＰＵ３１０が、ハングル文字入力プログラム３２０ａをＲＯＭ３２０から読み出して実行する。 Then, the CPU 310 reads the Hangul character input program 320a from the ROM 320 and executes it.
　そして、ＨＤＤ３３０には、割当字母情報、定義情報、入力文字記号記憶テーブル、辞書が設けられる。割当字母情報、定義情報、入力文字記号記憶テーブル、辞書のそれぞれは、図４に示した割当字母情報３０ａ、定義情報３０ｂ、入力文字記号記憶テーブル３０ｃ、辞書３０ｄに対応する。 The HDD 330 is provided with assigned character information, definition information, an input character symbol storage table, and a dictionary. The assigned character information, definition information, input character symbol storage table, and dictionary correspond to the assigned character information 30a, definition information 30b, input character symbol storage table 30c, and dictionary 30d shown in FIG.
　そして、ＣＰＵ３１０は、割当字母情報、定義情報、入力文字記号記憶テーブル、辞書を読み出してＲＡＭ３４０に格納する。ＣＰＵ３１０は、ＲＡＭ３４０に格納された割当字母情報、定義情報、入力文字記号記憶テーブル、辞書を用いて、ハングル文字入力プログラム３２０ａを実行する。なお、ＲＡＭ３４０に格納される各データは、常に全てのデータがＲＡＭ３４０に格納される必要はなく、処理に必要なデータのみがＲＡＭ３４０に格納されれば良い。 Then, the CPU 310 reads the assigned character information, definition information, input character symbol storage table, and dictionary and stores them in the RAM 340. The CPU 310 executes the Hangul character input program 320a using the assigned character information, definition information, input character symbol storage table, and dictionary stored in the RAM 340. Each data stored in the RAM 340 does not always need to be stored in the RAM 340, and only the data necessary for the process may be stored in the RAM 340.
　なお、上記したハングル文字入力プログラム３２０ａについては、必ずしも最初からＨＤＤ３３０に記憶させておく必要はない。 Note that the Hangul character input program 320a is not necessarily stored in the HDD 330 from the beginning.
　例えば、コンピュータ３００に挿入されるフレキシブルディスク（ＦＤ）、ＣＤ－ＲＯＭ、ＤＶＤディスク、光磁気ディスク、ＩＣカードなどの「可搬用の物理媒体」にプログラムを記憶させておく。そして、コンピュータ３００がこれらからプログラムを読み出して実行するようにしてもよい。 For example, the program is stored in a “portable physical medium” such as a flexible disk (FD), a CD-ROM, a DVD disk, a magneto-optical disk, or an IC card inserted into the computer 300. Then, the computer 300 may read and execute the program from these.
　さらには、公衆回線、インターネット、ＬＡＮ、ＷＡＮなどを介してコンピュータ３００に接続される「他のコンピュータ（またはサーバ）」などにプログラムを記憶させておく。そして、コンピュータ３００がこれらからプログラムを読み出して実行するようにしてもよい。 Furthermore, the program is stored in “another computer (or server)” connected to the computer 300 via a public line, the Internet, a LAN, a WAN, or the like. Then, the computer 300 may read and execute the program from these.
