Description

この発明は、タッチパネル入力機能のついた表示画面を有する情報処理装置における文字入力方法に関するものである。   The present invention relates to a character input method in an information processing apparatus having a display screen with a touch panel input function.

従来、タッチパネル入力機能のついた表示画面を有する情報処理装置における文字入力は、スタイラスペンによるものと、手書入力によるものと、５０音キーによるものと、アルファベットキーによるものとがあった。手書入力による入力方法は、画面の書込枠の中に文字を書き込み、この手書文字をすでに登録されている文字に変換する手書認識による方法と、すでに登録されている文字の中から変換する候補を表示する手書検索による方法とがある。５０音キーによる入力方法は、表示画面に５０音表にもとづいたキーを表示させ、目的の仮名のキーを押すことにより文字を入力する。アルファベットキーによる入力方法は、表示画面にすべてのアルファベットのキーを表示させ、目的のアルファベットのキーを押すことによりアルファベットを入力したり、ローマ字入力により仮名を入力する。入力手段は、情報処理装置が小型の場合そのほとんどがスタイラスペンを使用している。手書入力にはスタイラスペンが必要であり、５０音キーやアルファベットキーによる入力の場合でも、表示画面が狭くてキーが小さい場合はスタイラスペンが必要である。なおＰＤＡやタブレットＰＣのような小型の情報処理装置の場合、スタイラスペンは装置に収納されている。小型の情報処理装置を操作して文字入力するには、左手で情報処理装置を持ち、右手で情報処理装置からスタイラスペンを抜き取り、右手で持ったスタイラスペンで文字入力の操作をおこなう。ＡＴＭなどのように情報処理装置が大型の場合は、画面に５０音のキーボードが表示される。
特公平０７−０３８１４９号公報 Conventionally, character input in an information processing apparatus having a display screen with a touch panel input function has been performed by a stylus pen, by handwriting input, by a 50-sound key, or by an alphabet key. The handwriting input method includes handwriting recognition that writes characters in the writing frame on the screen and converts these handwritten characters to already registered characters, as well as already registered characters. There is a method by handwriting search that displays candidates for conversion. In the input method using the 50-sound key, a key based on the 50-sound table is displayed on the display screen, and a character is input by pressing the target kana key. In the input method using alphabet keys, all alphabet keys are displayed on the display screen, and an alphabet is input by pressing a target alphabet key, or a kana is input by romaji input. When the information processing apparatus is small, most of the input means use a stylus pen. A stylus pen is required for handwriting input. Even when input is performed using a 50 tone key or an alphabet key, a stylus pen is required when the display screen is narrow and the keys are small. In the case of a small information processing apparatus such as a PDA or a tablet PC, the stylus pen is accommodated in the apparatus. To input characters by operating a small information processing device, hold the information processing device with the left hand, pull out the stylus pen from the information processing device with the right hand, and perform character input operations with the stylus pen held with the right hand. When the information processing apparatus is large, such as ATM, a 50-sound keyboard is displayed on the screen.
Japanese Patent Publication No. 07-038149

上記従来のタッチパネル入力機能のついた表示画面を有する情報処理装置における文字入力方法には、次のような問題があった。   The character input method in the information processing apparatus having the display screen with the conventional touch panel input function has the following problems.

５０音キーやアルファベットキーのキーボードを表示して文字を入力する場合、キーの数が多いので押すキーを捜すまでに時間がかかり、一個一個のキーが小さいので見にくく、しかも接近しあっているため間違って別のキーを押してしまいやすく、指の移動距離も長くなる。入力を急げばそれだけ打ち間違いも多くなる。キーボードは、小さな文字が画面に一杯表示されて画面が塞がってしまうため、入力された文字を表示する画面の余裕が少ない。   When entering characters by displaying a keyboard with 50-sound keys or alphabet keys, it takes time to find the key to press because there are many keys, and it is difficult to see because each key is small, and they are close together. It's easy to accidentally press another key, and your finger moves longer. The faster you type, the more mistakes you make. Since the keyboard fills up the screen with small characters displayed on the screen, there is little room on the screen for displaying the input characters.

スタイラスペンを用いて手書入力をする場合、楷書で正確に書き込まなければならないため時間がかかり、しかも誤認識する頻度が高く、正しい文字を入力するには非常に根気を必要とする。スタイラスペンを使ってキーを押すことにより文字入力する場合、ペン先で目的のキーを押すという意外に面倒な作業に耐えなければならない。スタイラスペンは小型の情報処理装置に収納しなければならない場合が多いので非常に細くて小さいため、ペンとして非常に使いづらい。スタイラスペンは破損したり紛失したりしやすく、スタイラスペンがなければ文字入力ができなくなる。スタイラスペンを用いずに指で手書入力をしても、指先は太いので正確に書き込めないため希望する文字を入力することはできない。指でキーボードを操作すると、指先が太いので複数のキーを同時に押してしまうことが多く、希望した文字とは別の文字が入力されてしまいやすい。スタイラスペンを取って手に持つまでの時間のロスがある。小型の情報処理装置の場合、本体を片手に持ちもう片方の手でスタイラスペンを握って文字入力するので、両手を使用しなければ文字入力ができない。また、小型の情報処理装置にはスタイラスペンを収納するスペースを確保しなければならないため、小型化を制約する要因となっている。   When handwriting is input using a stylus pen, it takes time because it must be written accurately with a handwriting, and the frequency of misrecognition is high, and it takes much patience to input correct characters. When a character is input by pressing a key using a stylus pen, it is necessary to endure an unexpectedly troublesome task of pressing a target key with the pen tip. Since the stylus pen must be housed in a small information processing apparatus, it is very thin and small, so it is very difficult to use as a pen. The stylus pen is easily damaged or lost, and character input cannot be performed without the stylus pen. Even if handwriting is input with a finger without using a stylus pen, the desired tip cannot be input because the fingertip is thick and cannot be written accurately. When the keyboard is operated with a finger, a fingertip is thick, so a plurality of keys are often pressed at the same time, and a character different from the desired character is likely to be input. There is a loss of time to take the stylus pen and hold it in your hand. In the case of a small information processing apparatus, characters are input by holding the main body in one hand and holding the stylus pen with the other hand, so that characters cannot be input unless both hands are used. In addition, a small information processing apparatus has to secure a space for storing the stylus pen, which is a factor that restricts downsizing.

入力モードの切替え作業には、たとえばひらがな→カタカナ→英文字→数字というように、希望する入力モードになるまでボタンを何回も押さなければならないものや、入力モード別のボタンは用意されているが、その度にキーの中から細かいボタンを探し出して押さなければならないものがあり、それらは時間のロスが大きいばかりでなく文字入力に集中している思考を頻繁に中断することになる。   For input mode switching work, for example, hiragana → katakana → English letters → numbers, you have to press the button many times until you enter the desired input mode, and buttons for each input mode are prepared However, there are things that you have to find and press a small button from the key each time, and they not only have a great time loss, but also frequently interrupt thoughts that are concentrated on character input.

タッチパネル入力機能のついた表示画面を有する情報処理装置、殊にはＰＤＡやタブレットＰＣといった小型の情報処理装置の普及を妨げている理由の一つとして、上記したように文字入力方法が非常に面倒であることがあげられる。   As mentioned above, the character input method is very troublesome as one of the reasons for hindering the spread of small information processing devices such as PDAs and tablet PCs, which have a display screen with a touch panel input function. It can be mentioned.

本発明は、上記した従来の問題点を解決し、正確かつスピーディでしかも操作が簡単な文字入力方法を提供することを目的とする。   An object of the present invention is to solve the above-mentioned conventional problems and to provide a character input method that is accurate, speedy and easy to operate.

上記目的を達成するための文字入力方法として、本発明の請求項１では、タッチパネル入力機能を有する情報処理装置の表示画面に、文字入力用キーとして縦３列横４列計１２個のキーからなる１２キーを表示し、キーを押すことによりキーに割り当てられた文字が入力でき、１個のキーに対して複数の文字が割り当てられている場合はそのキーを連続して押す回数に応じて文字を次々に変更でき、希望する文字が現れるまでキーを押すことにより文字が入力できることを特徴とすることを特徴とする。   As a character input method for achieving the above-mentioned object, according to claim 1 of the present invention, a display screen of an information processing apparatus having a touch panel input function can be used from a total of twelve keys in three columns and four columns as character input keys. 12 keys are displayed, and when a key is pressed, a character assigned to the key can be input. When a plurality of characters are assigned to one key, the number of times the key is continuously pressed is displayed. Characters can be changed one after another, and a character can be input by pressing a key until a desired character appears.

また、本発明の請求項２では、タッチパネル入力機能を有する情報処理装置の表示画面に、文字入力用キーとして縦３列横４列計１２個のキーからなる１２キーと別枠とを表示し、キーを押すことによりキーに割り当てられた文字が入力でき、１個のキーに対して複数の文字が割り当てられている場合は、そのキーを押すとそれらの文字が別枠内に文字入力キーとして表示され、この別枠内の文字入力キーは他の１２キーを押すまでは表示されたままであり、別枠内に表示された希望する文字入力キーを押すことにより文字が入力できることを特徴とする。   Further, according to claim 2 of the present invention, 12 keys consisting of a total of 12 keys in 3 columns and 4 columns and a separate frame are displayed on the display screen of the information processing apparatus having a touch panel input function, When a key is pressed, the characters assigned to the key can be entered, and when multiple characters are assigned to one key, pressing that key displays those characters as character input keys in a separate frame. The character input key in this separate frame remains displayed until the other 12 keys are pressed, and a character can be input by pressing the desired character input key displayed in the separate frame.

また、本発明の請求項３では、タッチパネル入力機能を有する情報処理装置の表示画面に、文字入力用キーとして縦３列横４列計１２個のキーからなる１２キーを表示し、キーを押すことによりキーに割り当てられた文字が入力でき、１個のキーに対して複数の文字が割り当てられている場合は、そのキーを押すとそれらの文字は押したキーが属する列と隣接するキーの列との中間上にポップアップ表示された別枠内に一列の文字入力キーとして表示され、別枠の幅は下になっている１２キーに表示されている文字に重ならない程度であり、別枠は他の１２キーを押すまでは開かれたままの状態に保たれており、別枠内に表示された希望する文字入力キーを押すことにより文字が入力できることを特徴とする。   According to claim 3 of the present invention, 12 keys including 12 keys in total of 3 rows and 4 columns are displayed on the display screen of the information processing apparatus having a touch panel input function, and the keys are pressed. If a character assigned to a key can be entered, and multiple characters are assigned to one key, when that key is pressed, those characters will be displayed in the column adjacent to the column to which the pressed key belongs. It is displayed as a character input key in a row in a separate frame popped up in the middle of the column, and the width of the separate frame is such that it does not overlap with the characters displayed in the 12 keys below, It is kept open until the 12 key is pressed, and a character can be input by pressing a desired character input key displayed in another frame.

また、本発明の請求項４では、タッチパネル入力機能を有する情報処理装置の表示画面に、文字入力用キーとして縦３列横４列計１２個のキーからなる１２キーを表示し、左から右へ一番上の横１列目に１〜３を横２列目に４〜６を横３列目に７〜９を横４列目の中央に０の数字を配し、入力できる各文字にあらかじめ２桁の数字が割り当てられており、希望する文字に割り当てられている１桁目と２桁目のキーを押すことにより文字が入力できることを特徴とする。   According to claim 4 of the present invention, 12 keys comprising 12 keys in total of 3 rows and 4 columns are displayed on the display screen of the information processing apparatus having a touch panel input function, and the left to right 1 to 3 in the first horizontal row, 4 to 6 in the second horizontal row, 7 to 9 in the third horizontal row, and 0 in the middle of the fourth horizontal row A two-digit number is assigned in advance, and a character can be input by pressing the first and second digit keys assigned to the desired character.

また、本発明の請求項５では、前記した請求項１、２、３又は４記載の文字入力方法において、１２キーに割り当てられている文字の種類に、ひらがな、カタカナ、英文字、数字を有し、希望する入力モードに切替えることにより、希望する種類の文字が入力できることを特徴とする。   According to claim 5 of the present invention, in the character input method according to claim 1, 2, 3 or 4, the type of characters assigned to the 12 keys includes hiragana, katakana, English letters, and numbers. In addition, a desired type of character can be input by switching to a desired input mode.

また、本発明の請求項６では、前記した請求項１、２、３、４又は５記載の文字入力方法において、表示画面に入力モード切替用のタブを表示し、希望する入力モードが表示されたタブを押して入力モードを切替えることにより、希望する入力モードで文字が入力できることを特徴とする。   According to claim 6 of the present invention, in the character input method according to claim 1, 2, 3, 4 or 5, an input mode switching tab is displayed on the display screen, and a desired input mode is displayed. By switching the input mode by pressing the tab, characters can be input in the desired input mode.

また、本発明の請求項７では、前記した請求項１、２、３、４、５又は７記載の文字入力方法において、表示画面の一部に文字入力用の１２キーを表示し、空いている部分を通常のディスプレイ表示部として用い、入力された文字が通常のディスプレイ表示部に表示されることを特徴とする。   According to claim 7 of the present invention, in the character input method according to claim 1, 2, 3, 4, 5 or 7, the 12 keys for character input are displayed on a part of the display screen, And the input character is displayed on the normal display unit.

また、本発明の請求項８では、前記した請求項１、２、３、４、５、６又は７記載の文字入力方法において、表示画面の下方に文字入力用の１２キーを表示し、空いている部分を通常のディスプレイ表示部として用い、入力された文字が通常のディスプレイ表示部に表示されることを特徴とする。   Further, according to claim 8 of the present invention, in the character input method according to claim 1, 2, 3, 4, 5, 6 or 7, the 12 keys for character input are displayed below the display screen, and are empty. The displayed character is used as a normal display display unit, and the input character is displayed on the normal display display unit.

本発明の情報処理装置の文字入力方法は、１２キー方式なのでキーの数が少なく、非常に見やすく、キーを探す時間がほとんど不要で、指で正確に押しやすいため、入力が正確かつスピーディーでしかも操作が簡単である。また、１２キーの配置が携帯電話と同じなので、多くの人が操作方法になじみやすい。また、１２キーは縦３列横４列と縦も横も少ないため、１２キーを表示できる表示画面の縦幅や横幅が比較的狭い場合であっても、携帯電話のボタン部程度の面積があれば十分表示することができる。また、ＰＤＡやタブレットＰＣなど小型の情報処理装置で表示画面が小さい場合でも、キーの数が少なくキー１個あたりの面積を十分にとることができるので、非常に文字入力操作がしやすくなる。また、タッチパネル入力機能のついた表示画面を有する情報処理装置であれば（たとえば、ＰＤＡやタブレットＰＣやＡＴＭ等。）、従来のハードをそのまま利用することができる。携帯電話と同じ１２キーを利用して文字入力できるようになるため、これまで足踏み状態であったＰＤＡやタブレットＰＣを広く普及させることができる。指でキーを押すだけで文字入力ができるので、スタイラスペンは必要なくなる。スタイラスペンを収納するスペースが不要となるので、情報処理装置をさらに小型化できる。スタイラスペンによる余分な作業がいらないので、その分の時間のロスがなくなる。小型の情報処理装置の場合、携帯電話のように片手で持ちながらその手の親指だけでキーを操作して文字入力することができる。その場合もう一方の手はまったく使わなくてよくなる。また、１個のキーに１文字しか割り当てられていない状態であれば、そのキーを１回押すだけで割り当てられた文字を入力することができる。   The character input method of the information processing apparatus according to the present invention is a 12-key system, which has a small number of keys, is very easy to see, requires almost no time to search for keys, and is easy to press accurately with a finger, so that input is accurate and speedy. Easy to operate. In addition, since the 12-key arrangement is the same as that of a mobile phone, many people are familiar with the operation method. In addition, since the 12 keys are 3 rows by 4 rows and are small in both length and width, even if the display screen capable of displaying the 12 keys has a relatively narrow vertical width or horizontal width, the area of the button portion of a mobile phone is about the same. If there is enough, it can be displayed. Further, even when a small information processing apparatus such as a PDA or a tablet PC has a small display screen, the number of keys is small and a sufficient area per key can be obtained, which makes it very easy to perform character input operations. In addition, if the information processing apparatus has a display screen with a touch panel input function (for example, PDA, tablet PC, ATM, etc.), conventional hardware can be used as it is. Since characters can be input using the same 12 keys as mobile phones, PDAs and tablet PCs that have been in a stepped state can be widely used. A stylus pen is no longer necessary because characters can be input by simply pressing a key with a finger. Since a space for storing the stylus pen is not required, the information processing apparatus can be further downsized. No extra work with the stylus pen is required, so there is no loss of time. In the case of a small information processing apparatus, characters can be input by operating a key only with the thumb of the hand while holding it with one hand like a mobile phone. In that case, the other hand does not have to be used at all. If only one character is assigned to one key, the assigned character can be input by pressing the key once.

特に上記した請求項１記載の発明によれば、１２キーだけの操作で文字入力ができる。たとえばキーに５０音の行の文字を割り当てた場合、あ行のキーを押すたびに「あ」→「い」→「う」→「え」→「お」と入力される文字の表示が変わり、希望する文字が出たところでキーの連続操作をやめる方法である。この方法によれば、携帯電話の文字入力と同じ方式となるため、戸惑うことなくすぐに正確かつスピーディーでしかも簡単に小型情報処理装置の文字入力を行うことができるようになる。   In particular, according to the first aspect of the present invention, characters can be input by operating only 12 keys. For example, if a 50-line character is assigned to a key, each time you press the key on that line, the display of the characters that are entered “A” → “I” → “U” → “E” → “O” changes. This is a method to stop the continuous operation of the key when the desired character appears. According to this method, since it is the same method as the character input of the mobile phone, the character input of the small information processing apparatus can be performed quickly, accurately and quickly without confusion.

特に上記した請求項２記載の発明によれば、１２キーと別枠が表示され、１２キーと別枠内に表示された文字入力キーの操作によって文字入力ができる。たとえばキーに５０音の行の文字を割り当てた場合、あ行のキーを押せば別枠内に「あいうえお」の５個の文字入力キーが表示され、希望する文字入力キーを押す方法である。この方法によれば、１２キーへの５０音の行の配置は携帯電話の文字入力と同じ方式であるため、戸惑うことなくすぐに正確かつスピーディーでしかも簡単に小型情報処理装置の文字入力を行うことができるようになる。しかも、別枠内に文字入力キーが表示され、かつ、同じ別枠内の文字入力であれば１２キーの操作は不要なので、携帯電話よりもキーを押す回数が平均すると少なくてすみ、また、携帯電話では希望する文字を通過した場合は一周するまで押し続けなければならないのに対して希望する文字へストレートにアクセスでき、その結果として携帯電話よりも正確かつスピーディーにしかも簡単な操作で文字入力できる。携帯電話の方法では文字入力するのにキーを何回押す必要があるかというと、一つのキーに付属した文字が５文字として計算すれば、平均２．５回であるが、この発明の方法による文字入力によればキーと文字入力キーを押した合計であるから２回であり、携帯電話よりも０．５回押す回数が少なくてすむ。別枠内の文字を入力している間はキーを押す必要がないので、一文字の入力に要する押す回数の平均はさらに低くなる。別枠は一定の位置に固定的に表示されるので、押すべき文字入力キーの位置に迷わないですむ。   In particular, according to the second aspect of the present invention, the 12 keys and the separate frame are displayed, and characters can be input by operating the character input keys displayed in the 12 keys and the separate frame. For example, when a 50-line character is assigned to a key, if the key of that line is pressed, five character input keys “Aiueo” are displayed in another frame, and the desired character input key is pressed. According to this method, since the arrangement of 50 sound lines on the 12 keys is the same as the character input of the mobile phone, the character input of the small information processing apparatus can be performed accurately, speedily and easily without confusion. Will be able to. Moreover, if a character input key is displayed in a separate frame and the character input is in the same separate frame, the operation of the 12 keys is unnecessary, so the number of times of pressing the key is smaller than that of the mobile phone on average. Then, if the desired character is passed, it must be kept pressed until it goes around, but the desired character can be accessed straight, and as a result, the character can be input more accurately, speedily and with simple operation than a mobile phone. According to the method of the cellular phone, the number of times the key needs to be pressed to input the character is 2.5 times on average if the character attached to one key is calculated as 5 characters. According to the character input by, it is twice because it is the sum of pressing the key and the character input key, and the number of times of pressing 0.5 times is less than that of the mobile phone. Since it is not necessary to press a key while a character in another frame is being input, the average number of presses required to input a single character is even lower. Since the separate frame is fixedly displayed at a certain position, it is not necessary to be confused about the position of the character input key to be pressed.

特に上記した請求項３記載の発明によれば、１２キーとそのキーを押すことによりポップアップした別枠内に割り当てられた複数の文字の文字入力キーが表示され、１２キーと別枠内に表示された文字入力キーの操作によって文字入力ができる。たとえばキーに５０音の行の文字を割り当てた場合、あ行のキーを押せばポップアップ表示された別枠内に「あいうえお」の５個の文字入力キーが表示され、希望する文字入力キーを押す方法である。別枠は隣り合った列と列の間の上に重なって表示され、１２キーの表面に表示されている文字は見える状態となるため１２キーの操作に支障を生じることはなく、また、１２キーの上にポップアップするので別枠で１２キー以外の表示画面のエリアを使用せずにすむ。この方法によれば、１２キーへの５０音の行の配置は携帯電話の文字入力と同じ方式であるため、戸惑うことなくすぐに正確かつスピーディーでしかも簡単に小型情報処理装置の文字入力を行うことができるようになる。しかも、別枠内に文字入力キーが表示され、かつ、同じ別枠内の文字入力であれば１２キーの操作は不要なので、携帯電話よりもキーを押す回数が平均すると少なくてすみ、また、携帯電話では希望する文字を通過した場合は一周するまで押し続けなければならないのに対して希望する文字へストレートにアクセスでき、その結果として携帯電話よりも正確かつスピーディーにしかも簡単な操作で文字入力できる。携帯電話の方法では文字入力するのにキーを何回押す必要があるかというと、一つのキーに付属した文字が５文字として計算すれば、平均２．５回であるが、この発明の方法による文字入力によればキーと文字入力キーを押した合計であるから２回であり、携帯電話よりも０．５回押す回数が少なくてすむ。別枠内の文字を入力している間はキーを押す必要がないので、一文字の入力に要する押す回数の平均はさらに低くなる。押したキーの近くに別枠を表示することにより、指の移動距離を短くし、効率よく文字を入力することができる。   In particular, according to the third aspect of the present invention, the 12 keys and the character input keys of a plurality of characters assigned in the separate frame popped up by pressing the key are displayed and displayed in the separate frame from the 12 keys. Characters can be input by operating the character input keys. For example, when a 50-line character is assigned to a key, if you press the key on that line, the five character input keys “Aiueo” will be displayed in the pop-up window, and you can press the desired character input key. It is. The separate frame is displayed so as to overlap between adjacent rows, and the characters displayed on the surface of the 12 keys can be seen, so there is no trouble in the operation of the 12 keys. Since it pops up on top of the screen, it is not necessary to use a display screen area other than 12 keys in a separate frame. According to this method, since the arrangement of 50 sound lines on the 12 keys is the same as the character input of the mobile phone, the character input of the small information processing apparatus can be performed accurately, speedily and easily without confusion. Will be able to. Moreover, if a character input key is displayed in a separate frame and the character input is in the same separate frame, the operation of the 12 keys is unnecessary, so the number of times of pressing the key is smaller than that of the mobile phone on average. Then, if the desired character is passed, it must be kept pressed until it goes around, but the desired character can be accessed straight, and as a result, the character can be input more accurately, speedily and with simple operation than a mobile phone. According to the method of the cellular phone, the number of times the key needs to be pressed to input characters is 2.5 times on average if the number of characters attached to one key is calculated as 5 characters. According to the character input, the total of the key and the character input key is pressed twice, so that the number of times of pressing is 0.5 times less than that of the mobile phone. Since it is not necessary to press a key while a character in another frame is being input, the average number of presses required to input a single character is even lower. By displaying another frame near the pressed key, the distance of finger movement can be shortened and characters can be input efficiently.

特に上記した請求項４記載の発明によれば、１２キーの１０個のキーに０から９の数字を配置し、２桁の数字を押すことにより文字入力できる。たとえば、最初の数字に５０音の行を割り当て、２番目の数字にその行の何番目の文字であるかによって該当する２桁の数字に割り当てられた文字を入力する方法である。この場合、１０の位の数字の１にあ行が割り当てられているとすると、１と１を押せば「あ」が、１と２を押せば「い」が、１と３を押せば「う」が、１と４を押せば「え」が、１と５を押せば「お」が入力できる。ポケベル方式の文字入力が可能となる。この方法によれば、１２キーの数字の配置が携帯電話と同じであると同時に、入力方式がポケベルと同じであるため、すでにポケベル方式の文字入力に慣れている人は戸惑うことなくすぐに正確かつスピーディーでしかも簡単に小型情報処理装置の文字入力を行うことができるようになる。携帯電話の方法では文字入力するのにキーを何回押す必要があるかというと、一つのキーに付属した文字が５文字として計算すれば、平均２．５回であるが、この発明の方法による文字入力によればキーと文字入力キーを押した合計であるから２回であり、携帯電話よりも０．５回押す回数が少なくてすむ。   In particular, according to the invention described in claim 4, it is possible to input characters by placing numbers 0 to 9 on 10 keys of 12 keys and pressing a 2-digit number. For example, a line of 50 sounds is assigned to the first number, and the character assigned to the corresponding two-digit number is input to the second number depending on the number of the character in the line. In this case, if a line is assigned to the number 1 of the tenth place, “A” is pressed if 1 and 1 are pressed, “I” is pressed if 1 and 2 are pressed, and “1” is pressed if 1 and 3 are pressed. If you press 1 and 4, you can enter “e”, and if you press 1 and 5, you can enter “o”. Pager type character input is possible. According to this method, the 12-key number layout is the same as that of a mobile phone, and at the same time, the input method is the same as that of a pager. In addition, it is possible to input characters in a small information processing apparatus quickly and easily. According to the method of the cellular phone, the number of times the key needs to be pressed to input characters is 2.5 times on average if the number of characters attached to one key is calculated as 5 characters. According to the character input by, it is twice because it is the sum of pressing the key and the character input key, and the number of times of pressing 0.5 times is less than that of the mobile phone.

特に上記した請求項５記載の発明によれば、ひらがな、カタカナ、英文字、数字の中から、希望する文字の種類を選んで文字入力できる。   In particular, according to the invention described in claim 5, it is possible to input characters by selecting a desired character type from hiragana, katakana, English characters, and numbers.

特に上記した請求項６記載の発明によれば、希望する文字入力モードのタブを指で押すだけで、文字入力モードを切替えることができる。タブであるから、指で押しやすい大きさにすることができる。指でタブを押すだけなので、文字入力の流れを邪魔することなく、簡単に切り替えることができる。   In particular, according to the invention described in claim 6, the character input mode can be switched by simply pressing the tab of the desired character input mode with a finger. Since it is a tab, it can be made easy to press with a finger. Since the user only needs to press the tab, it can be switched easily without disturbing the flow of character input.

特に上記した請求項７記載の発明によれば、表示画面の一部に１２キーを表示して、空いている部分を通常のディスプレイ表示部として用い、通常のディスプレイ表示部に入力された文字を表示することができる。１２キーだけで表示画面を塞ぐことはない。文字入力の結果を確認しながら文字入力をすることができる。   In particular, according to the invention described in claim 7, the 12 keys are displayed on a part of the display screen, the vacant part is used as a normal display display part, and characters input to the normal display display part are displayed. Can be displayed. The display screen is not blocked with only 12 keys. Character input can be performed while checking the result of character input.

特に上記した請求項８記載の発明によれば、表示画面の下方に１２キーを表示して、空いている部分を通常のディスプレイ表示部として用い、通常のディスプレイ表示部に入力された文字を表示することができる。１２キーだけで表示画面を塞ぐことはない。表示画面の下方に１２キーを表示することにより文字入力がしやすくなって操作性が向上し、上方にある通常のディスプレイ表示部の表示画面を大きくとって入力された文字を表示するエリアを広くとることができ、しかも、文字入力の最中に手が邪魔をして通常のディスプレイ表示部が見えにくくなることはない。文字入力の結果を確認しながら文字入力をすることができる。   In particular, according to the invention described in claim 8, the 12 keys are displayed at the bottom of the display screen, the vacant part is used as the normal display display unit, and the characters input to the normal display display unit are displayed. can do. The display screen is not blocked with only 12 keys. Displaying 12 keys at the bottom of the display screen makes it easier to input characters and improves operability, and the display screen of the normal display section at the top is enlarged to widen the area for displaying input characters. In addition, the hand does not get in the way of character input, and the normal display unit is not difficult to see. Character input can be performed while checking the result of character input.

５０音やアルファベットのキーボードや、スタイラスペンによる文字入力の煩わしさを解決し、正確かつスピーディーでしかも操作が簡単な文字入力方法を目的とし、タッチパネル入力機能を有する情報処理装置の表示画面に、文字入力用キーとして縦３列横４列計１２個のキーからなる１２キーを表示し、この１２キーを利用することにより実現した。   A character input method that solves the hassle of inputting characters using a 50-sound or alphabet keyboard and a stylus pen, and that is accurate, speedy, and easy to operate. This is realized by displaying 12 keys consisting of 12 keys in total of 3 rows and 4 columns as input keys and using these 12 keys.

以下、添付図面に基づき本発明に係わる文字入力方法について説明するが、本発明は以下の実施例にのみ限定されるべきものではないことはいうまでもない。   Hereinafter, although the character input method concerning this invention is demonstrated based on an accompanying drawing, it cannot be overemphasized that this invention should not be limited only to the following Examples.

図中１は、情報処理装置である。図１〜図１２は小型の情報処理装置１の一種のＰＤＡであり、図１２は情報処理装置１を片手で持ちながら本発明の文字入力方法によりその手の親指だけで文字入力をしている状態を表している。図１３は大型の情報処理装置１の一種のＡＴＭであり、本発明の文字入力方法により人差し指だけで文字入力をしている状態を表している。タッチパネル式の表示画面２であれば、既成のＰＤＡなどの情報処理装置１をそのまま使用することができる。図中２は、情報処理装置１のタッチパネル入力機能を有する表示画面２である。図中３は、横３列縦４列の１２個のキー４から構成された１２キーである。図１の１２キー３は、キー４の枠のみを示しているが、実際にはこのキー４の上にはキー４によって入力することのできる割り当てられた文字や、複数ある文字の代表する文字などが表示される。本実施例のキー４は四角い形をしていて隣接するキー４同士が密着しているが、キー４の形はこれに限らないし、隣のキー４との間が開いていてもよい。１２キー３の全体の大きさは、表示画面２の大きさの許す範囲であればある程度大きくて構わないし、最低でも携帯電話の文字入力ボタン程度の大きさであればよい。１２キー３を表示画面２に表示する位置は、基本的に自由であるが、表示画面２の上下に余裕がある場合は下方の方が操作性がよく、表示画面２の左右に余裕がある場合は入力に用いる手の側の方が操作性がよい。図１〜図１３のすべての１２キー３は表示画面２の下方に表示されており、図１３における１２キー３は表示画面２の右側に表示されている。１２キー３を文字入力など必要なときだけ表示画面２に表示して必要ないときは表示しないといった工夫がありえたとしても、文字入力方法に１２キー３が用いられる以上は、本発明の文字入力方法に含まれるものである。また、１２キー３の表示画面２への表示場所を必要に応じて変更移動できる工夫がありえたとしても、文字入力方法に１２キー３が用いられる以上は、本発明の文字入力方法に含まれるものである。また、１２キー３の大きさやキー４のデザインを変更する工夫がありえたとしても、文字入力方法に１２キー３が用いられる以上は、本発明の文字入力方法に含まれるものである。１２キー３への文字の割り当てとしては、携帯電話の方式に準じるのが現実的であるし、利用者もそのほうが混乱なく文字入力することができる。しかし、文字入力の目的によっては必要でない文字があるので、場合によっては最初から割り当てからはずしてもよい（たとえば、「アドレス表示」「＊」「♯」など。）。入力モードは、１種類しかない固定式と何種類もある切替え式のどちらの場合もありえるし、ひらがな入力モードにおいては無変換のみの場合と漢字変換できる場合のどちらもありえるし、半角入力モードを備えている場合もありえるし、絵文字入力モードを備えている場合もありえる。入力モードがひらがなの場合、たとえば、１２キー３のキー４の上に図２〜図７に示すような文字を表示し、１２キー３の左から右へ、一番上の横１列目のキー４に「あ行」「か行」「さ行」を、横２列目のキー４に「た行」「な行」「は行」を、横３列目のキー４に「ま行」「や行」「ら行」を、横４列目のキー４に「濁点化→半濁点化→無濁点化」「わをんー、。」「記号」を割り当てる。入力モードがカタカナの場合、たとえば、１２キー３のキー４の上に図８に示すような文字を表示し、１２キー３の左から右へ、一番上の横１列目のキー４に「ア行」「カ行」「サ行」を、横２列目のキー４に「タ行」「ナ行」「ハ行」を、横３列目のキー４に「マ行」「ヤ行」「ラ行」を、横４列目のキー４に「濁点化→半濁点化→無濁点化」「ワヲンー、。」「記号」を割り当てる。入力モードが英文字の場合、たとえば、１２キー３のキー４の上に図９に示すような文字を表示し、１２キー３の左から右へ、一番上の横１列目のキー４に「＠．／＿１スペース」「ＡＢＣａｂｃ２」「ＤＥＦｄｅｆ３」を、横２列目のキー４に「ＧＨＩｇｈｉ４」「ＪＫＬｊｋｌ５」「ＭＮＯｍｎｏ６」を、横３列目のキー４に「ＰＱＲＳｐｑｒｓ７」「ＴＵＶｔｕｖ８」「ＷＸＹＺｗｘｙｚ９」を、横４列目のキー４に「アドレス表示」「，．０」「記号」を割り当てる。入力モードが数字やポケベル入力の場合、たとえば、１２キー３のキー４の上に図１０図１１に示すような文字を表示し、１２キー３の左から右へ、一番上の横１列目のキー４に「１」「２」「３」を、横２列目のキー４に「４」「５」「６」を、横３列目のキー４に「７」「８」「９」を、横４列目のキー４に「＊」「０」「♯」を割り当てる。１２キー３のキー４の上に表示する文字は、上記したように入力モードによって変えてもよいし、携帯電話のボタンのように、１２キー３の左から右へ、一番上の横１列目のキー４に「あ＠１」「かＡＢＣ２」「さＤＥＦ３」を、横２列目のキー４に「たＧＨＩ４」「なＪＫＬ５」「はＭＮＯ６」を、横３列目のキー４に「まＰＱＲＳ７」「やＴＵＶ８」「らＷＸＹＺ９」を、横４列目のキー４に「゛゜＊」「わをん、。０」「記号♯」と表示したまま変えなくてもよい。   In the figure, reference numeral 1 denotes an information processing apparatus. 1 to 12 show a kind of PDA of a small information processing apparatus 1. FIG. 12 shows a character input with only the thumb of the hand by the character input method of the present invention while holding the information processing apparatus 1 with one hand. Represents a state. FIG. 13 is a kind of ATM of the large-scale information processing apparatus 1, and shows a state where characters are input only with the index finger by the character input method of the present invention. If the display screen 2 is a touch panel type, the information processing apparatus 1 such as an existing PDA can be used as it is. In the figure, reference numeral 2 denotes a display screen 2 having a touch panel input function of the information processing apparatus 1. In the figure, 3 is a 12 key composed of 12 keys 4 in 3 horizontal rows and 4 vertical columns. The 12 key 3 in FIG. 1 shows only the frame of the key 4, but in actuality, an assigned character that can be input by the key 4 or a representative character of a plurality of characters is placed on the key 4. Etc. are displayed. The key 4 of this embodiment has a square shape and the adjacent keys 4 are in close contact with each other. However, the shape of the key 4 is not limited to this, and the space between the adjacent keys 4 may be open. The total size of the 12 keys 3 may be large to some extent as long as the size of the display screen 2 allows, and may be at least as large as a character input button of a mobile phone. The position where the 12 key 3 is displayed on the display screen 2 is basically free. However, when there is a margin at the top and bottom of the display screen 2, the operability is better at the bottom and there is a margin at the left and right of the display screen 2. In this case, the operability is better on the hand side used for input. All the 12 keys 3 in FIGS. 1 to 13 are displayed below the display screen 2, and the 12 keys 3 in FIG. 13 are displayed on the right side of the display screen 2. Even if there is a contrivance that the 12 key 3 is displayed on the display screen 2 only when necessary, such as character input, and is not displayed when it is not necessary, the character input of the present invention will be performed as long as the 12 key 3 is used for the character input method It is included in the method. Further, even if there is a device that can change and move the display location of the 12 key 3 on the display screen 2 as necessary, the character input method of the present invention includes that the 12 key 3 is used as the character input method. Is. Even if the size of the 12 key 3 or the design of the key 4 can be changed, the character input method of the present invention is included as long as the 12 key 3 is used for the character input method. It is realistic to assign a character to the 12-key 3 in accordance with the method of the mobile phone, and the user can input characters without confusion. However, since there are characters that are not necessary depending on the purpose of character input, the assignment may be removed from the beginning (for example, “address display”, “*”, “#”, etc.). The input mode can be either a fixed type with only one type or a switching type with many types. In the hiragana input mode, there can be either no conversion or kanji conversion, and half-width input mode. It may be provided, or it may be provided with an emoji input mode. When the input mode is hiragana, for example, characters as shown in FIG. 2 to FIG. 7 are displayed on the key 4 of the 12 key 3, and the top row in the first horizontal row from the left to the right of the 12 key 3. Key 4 is “A”, “K”, “Sa”, the second column is “Ta”, “N”, “Ha”, and the third column is “4” "Ya row" and "Ra row" are assigned to the key 4 in the horizontal fourth column as "turbidation-> half-turbidization-> non-turbidization", "waon, ...", "symbol". When the input mode is Katakana, for example, characters as shown in FIG. 8 are displayed on the key 4 of the 12 key 3, and from the left to the right of the 12 key 3, the key 4 in the top horizontal row is displayed. “A”, “K”, “S”, “Ta”, “N”, “C” in key 4 in the second column, “Ma”, “Y” in key 4 in the third column. Rows and “La Rows” are assigned to the key 4 in the fourth horizontal row as “turbidization → half-turbidization → non-turbidization”, “Wow, ...”, “symbol”. When the input mode is an English character, for example, characters as shown in FIG. 9 are displayed on the key 4 of the 12 key 3, and the key 4 in the top horizontal row from the left to the right of the 12 key 3. “@. / _ 1 space”, “ABCabc2”, “DEFdef3”, “GHIghi4”, “JKLjkl5”, “MNOmno6” to key 4 in the second row, and “PQRSpqrs7”, “TUVtuv8”, “4” to key 4 in the third row. “WXYZwxyz9” and “address display” “, .0”, “symbol” are assigned to the key 4 in the fourth horizontal row. When the input mode is numeric or pager input, for example, characters as shown in FIG. 10 and FIG. 11 are displayed on the key 4 of the 12 key 3, and the top horizontal row from the left to the right of the 12 key 3 “1”, “2”, “3” for the key 4 in the second row, “4”, “5”, “6” for the key 4 in the second row, and “7”, “8”, “6” in the key 4 in the third row. “9” and “*”, “0”, and “#” are assigned to the key 4 in the fourth horizontal row. The character displayed on the key 4 of the 12 key 3 may be changed depending on the input mode as described above, or from the left to the right of the 12 key 3 like the button of the mobile phone, the top horizontal 1 “A @ 1”, “ABC2”, “SADEF3” is set to the key 4 in the row, “TaGHI4”, “NaJKL5”, “MNO6” is set to the key 4 in the horizontal row, and the key 4 in the horizontal row In addition, “MA PQRS7”, “TUV8”, and “WXYZ9” need not be changed while “4 ° *”, “Waon, .0”, “Symbol #” are displayed on the key 4 in the fourth horizontal row.
